Answer:
(x - 12)² + y² = 100
Step-by-step explanation:
The standard form of the equation of a circle is;
(x - a)² + (y - b)² = r²
where:
a and b are the coordinates of the centre of the circle
r is the radius
We are given the coordinates of the endpoints of the diameter as; (22,0) and (2,0)
Thus, the centre of the circle would be at the mid point of the endpoints of the diameter.
Coordinates of the centre is;
((22 + 2)/2), (0 +0)/2))
This is;
(12, 0)
So, a = 12 and b = 0
Now,to get the radius r, we will use the formula;
r = √[(x2 - x1)² + (y2 - y1)²]
Where;
(x1, y1) and (x2, y2) are 2 points namely (12,0) and (22, 0)
r = √[(12 - 22)² + (0 - 0)²]
r = √(-10)²
r = √100
r = 10
Thus,equation of the circle is;
(x - 12)² + (y - 0)² = 10²
(x - 12)² + y² = 100
b. Is the a discrete random variable, a continuous random variable, or not a random variable? time it takes for a light bulb to burn out A. It is a discrete random variable. B. It is a continuous random variable. C. It is not a random variable
Answer:
The correct answer is:
It is a continuous random variable (C)
Step-by-step explanation:
Continuous Random Variables are variables that do not take on a distinct value. They take on values that are a range of different possibilities to infinity. In continuous random variables, the values cannot be counted. In this example, the time it takes for a light bulb to burn out can be any rational number which is greater than 0, up to infinity; for instance, it can be 24 hours, 24.5 hours, 30.8 hours, 51.2 hours etc. There is an infinite possibility of the time it takes for the bulb to burn out.
Discrete Random Variables are ones in which the variables take on distinct values and nothing in between. Here, the outcomes can be counted. For example if a coin is tossed, there are only two possibilities which can be the outcome and that is either head, or tail. The number of possible outcome is 2, and there is nothing inbetween head or tail.

The number of problems assigned as homework by a savvy math professor is a function of the length of the class on a particular day, which is either 45 minutes, 90 minutes, or 135 minutes. He first multiplies the number of minutes by 4 and then divides that number by 9. Finally, he subtracts 12 from that amount. Which of the following functions best represents the number of math problems the professor assigns depending on the length of the class, t, in minutes?
Answer:f(t)=4/9t — 12
Step-by-step explanation:
1. 4 is being multiplied by t first then divided by 9 not by 4/9 so there shouldn’t be any parentheses.
2. 12 is being subtracted from this so it should be 4/9t—12.
3. Final answer: f(t)= 4/9t — 12
All Parent functions have both x- intercepts and y-intercepts EXCEPT. I. Linear II. Absolute Value III.Quadratic IV. Cubic V.Square root VI. Cube root VII. Reciprocal VIII. Exponential IX. Logarithmic
Answer:
Reciprocal, Exponential and Logarithmic.
Step-by-step explanation:
x intercept is the value of x where y value is 0.
y intercept is the value of y where x value is 0.
Let us have a look at the possibility for each parent function as given.
I. Linear
[tex]y =x[/tex]
When x = 0, y = 0 and
When y = 0, x = 0
Therefore, both x and y intercept exist.
II. Absolute value
[tex]y =|x|[/tex]
When x = 0, y = 0 and
When y = 0, x = 0
Therefore, both x and y intercept exist.
III. Quadratic
[tex]y =x^{2}[/tex]
When x = 0, y = 0 and
When y = 0, x = 0
Therefore, both x and y intercept exist.
IV. Cubic
[tex]y =x^3[/tex]
When x = 0, y = 0 and
When y = 0, x = 0
Therefore, both x and y intercept exist.
V. Square root
[tex]y =\sqrt x[/tex]
When x = 0, y = 0 and
When y = 0, x = 0
Therefore, both x and y intercept exist.
VI. Cube root
[tex]y =\sqrt[3]x[/tex]
When x = 0, y = 0 and
When y = 0, x = 0
Therefore, both x and y intercept exist.
VII. Reciprocal
[tex]y =\dfrac{1}x[/tex]
When [tex]x = 0, y \rightarrow \infty[/tex]
Therefore, both x and y intercept do not exist.
VIII. Exponential
[tex]y =b^x[/tex]
where b is any base:
When [tex]x = 0, y =1[/tex] therefore y intercept exists.
When we put y = 0, which is not possible
Therefore, both x and y intercept do not exist.
IX. Logarithmic
[tex]y =logx[/tex]
When [tex]x = 0, y \rightarrow[/tex] not defined
Therefore, both x and y intercept do not exist.

[tex]\frac{1}{8}[/tex]w = 14
Answer:
w = 112
Step-by-step explanation:
1/8w = 14
Multiply each side by 8
8*1/8w = 14*8
w = 112
Answer: w = 112
Explanation: If w is being multiplied by a fraction, simply multiply both sides of the equation by the reciprocal of that fraction to get w by itself.
So in this problem, since w is being multiplied by 1/8,
we multiply both sides of the equation by 8/1.
On the left, (8/1) (1/8) cancels out and on the right,
if you multiply 14 by 8/1, you get 112.
So w = 112.

Answer:
x = -12, a = 17
Step-by-step explanation:
You can use algebraic techniques to simplify two-step equations. They have a constant on one side of the equation and a variable with a coefficient on the other. However, for algebraic equations, most will require you to add or subtract a constant from the side with the variable.
4x + 7 = -41 can be simplified algebraically. Subtract 7 from both sides and then divide by 4.
4x + 7 = -41
4x = -48
x = -12
-4 - 2a = -38 can also be simplified algebraically. Add 4 to both sides and then divide by -2.
-4 - 2a = -38
-2a = -34
a = 17
Answer:
8 x = -12
12 a = 17
Step-by-step explanation:
8
4x + 7 = -41
4x = -41 - 7
4x = -48
x = -48/4
x = -12
probe:
4*-12 + 7 = -41
-48 + 7 = -41

A mechanic charged $220.28 to repair a car. The price included charges for 3 hours of labor and $126.53 for parts. How much does the mechanic charge per hour for labor?
Answer:
$31.25
Step-by-step explanation:
Let's set up an equation.
$220. 28 - total
$126.53 - cost for parts
3 - # of hours
? - price per hour
3h + $126.53 = $220.28
Subtract $126.53 from both sides.
3h = $93.75
Divide by 3.
h = $31.25
The mechanic charges $31.25 per hour for labor.

Let ABCD be a parallelogram such that AB = 10 , BC = 14, and Angle A = 45. Find the area of the parallelogram.
Will make person brainliest if answered within 15 minutes and is correct.
Answer:
Area of a parallelogram is base times height. Note that CD = AB & AD = BC
to find the height, draw a line from angle B perpendicular to the base b. Lets call the point of intersection at the base E. This constitutes a right triangle with AB as the hypotenuse. Using the law of sine to calculate the height h:
h/sin(A) = AB/sin(90°) ( sin(90°) = 1)
h = AB * sin(45°)
h = 10 * sin(45°)
Area = 14 * 10 * sin(45°) = 140 * sin(45°) ≈ 98.99 QEDexplanation:
Let ABCD be a parallelogram such that AB = 10 , BC = 14, and Angle A = 45. Find the area of the parallelogram. Please do not answer in decimal form. Answer using a square root
Answer:
70√2 units²
Step-by-step explanation:
(see attached for reference notes on parallelograms)
we are given ABCD is a parallelogram where
Short Length, AB = 10 units
Long Length, BC = 14 units
Angle A = 45°
The area of the parallelogram is hence,
= AB x BC sin 45°
= 10 x 14 x sin 45
= 140 sin 45° (recall from special angles, that sin 45° = 1/√2)
= 140/√2 (remove radical from denominator by multiplying by √2/√2)
= (140/√2) x (√2/√2)
=70√2 units²

Lin deposited $300 in a savings account that has a 2% interest rate per year. How much is in her account after 1 year? After 2 years? Diego wants to sell his bicycle. It cost $150 when he bought it but has depreciated by 15%. How much should he sell it for? I will give brainlyies
Answer:
Step-by-step explanation:
Lin after 1 year has 300+2*300/100=300+6=306 $
after 2 years has 306+2*306/100=306+6.12=312.12$
150-15*150/100=150-22.5=127.5 $ the price for the bicycle
The value after 20 years is $ 723.514
Solution:
Formula for Amount compounded annually is as follows:
Where,
"A" is the total amount
"p" is the principal sum
"r" is the rate of interest
"n" is the number of years
From given question,
p = $ 300
r = 4.5 %
n = 20 years
Substituting the values we get,
Thus value after 20 years is $ 723.514
PART 2)
2. Given data
Cost of bicycle = $150
Depreciation = 15%
Firstly let us calculate 15% of $150
(15/100)*150 =0.15*150
= $22.5
Since the value depreciated
We will minus the the depression from the initial amount
New amount = 150-22.5=
$127.5

Anona hires a decorator to redecorate her bedroom. The decorator offers her 2 different plans: the basic plan has
x wall-color options, x + 1 ceiling-color options, and x + 3 flooring options. The gold plan offers all of the basic plan
offerings, plus 3 additional options in each category.
If a layout includes a wall color, ceiling color, and flooring, which option correctly shows the comparison between the
total number of unique layouts offered by the basic and gold plans?
O 3x +4 < 3x +11
Ox3+4x2 + 3x < 6x + 42x2 + 72
Ox+4
Ox3+4x² + 3x < x + 13.x2 + 54x + 72
>
Answer:
The correct option is;
x³ + 4·x² + 3·x < x³ + 13·x² + 54·x + 72.
Step-by-step explanation:
The given parameters are;
The basic plan of the decorator = x wall-color options, x + 1 ceiling-colr options, and x + 3 floor options
The gold plan of the decorator = All of the basic plan options plus 3 additional options in each category
Therefore, the gold plan of the decorator = (x + 3) wall-color options, (x + 1 + 3) ceiling-color options, and (x + 3 + 3) floor options
The total number unique layouts offered by the basic plan = x × (x + 1) × (x + 3) = x³ + 4·x² + 3·x
Also, the total number unique layouts offered by the gold plan = (x + 3) × (x + 1 + 3) × (x + 3 + 3) = (x + 3) × (x + 4) × (x + 6) = x³ + 13·x² + 54·x + 72
Which gives;
The comparison between the total number of unique layouts offered by the basic and gold plans as x³ + 4·x² + 3·x < x³ + 13·x² + 54·x + 72.

The floor of a large ware house is rectangular in shape and its length is twice as long as its width. The area of the floor of the warehouse is 39,200 square feet. What is the length of the floor of the warehouse in feet?
Answer:
The length of the warehouse is 280 feet.
Step-by-step explanation:
Let A be the area of the warehouse floor, W be its width, and L be its length.
A = W * L
We know that the length is twice the width:
L = 2W
Substitute the second equation into the first equation and we get:
A = 2W * W
Solve for W (A = 39200):
39200 = 2W * W
39200 = 2W²
19600 = W²
W = 140
Plug that number into the second equation to get the length:
L = 2 * 140
L = 280
So the length of the warehouse is 280 feet, the width is 140 feet, and the total area is 39200 ft²

Sean runs 5 miles North of his house and then runs 3 miles East of his house. What is his displacement?
Answer: 5.83 milea
Step-by-step explanation:
As displacement is the shortest distance between two points. Now 5 miles north and 3 miles east so it makes a Right angle traingle and the hypotenuse is the displacement so
Displacement is (5^2 +3^2)^0.5 =5.83 miles.
The displacement is 5.83 miles.
What is a Triangle?A triangle in geometry is a three-sided polygon with three edges and three vertices.
As per the given data:
Miles Sean ran to the north of his house = 5 miles
Miles Sean ran to the east of his house = 3 miles
For finding the displacement, we have to find out the length of the line from the initial to the final position of Sean.
As Sean first ran north and then ran east, a right-angled triangle is made.
The displacement of Sean is given by the hypotenuse of this right-angled triangle.
The perpendicular is the distance ran in north.
The base is the distance ran in east.
Now, by using the Pythagoras theorem:
H² = P² + B²
H² = (5)² + (3)²
H² = 25 + 9
H² = 34
H = √34 = 5.83 miles
The displacement is 5.83 miles.
Hence, The displacement is 5.83 miles.

The terminal side of a 130° angle in standard position lies in the
quadrant.
Two angles that are coterminal to 130 are and
Answer:
The answer is below
Step-by-step explanation:
The angle 130° lies in the second quadrant since it is between 90° and 180°. Coterminal angles are angles that share the same initial and terminal side with an angle. For a angle, there are many coterminal angles, to find a coterminal angle all you have to add or subtract 360°.
The positive angle that is coterminal to 130° are:
130 + 360 = 490°
490 + 360 = 850°
The negative angle that is coterminal to 130° are:
130 - 360 = -230°
-230 - 360 = -590°
The terminal side of a 130° angle lies in the second quadrant.
Given angle measures 130°.
The whole graph plane is divided into four quadrants, namely first quadrant, second quadrant, third quadrant and fourth quadrant.
The first quadrant has range of angles from 0 degrees to 90 degrees.
The second quadrant has range of angles from 90 degrees to 180 degrees.
The third quadrant has range of angles from 180 degrees to 270 degrees.
The fourth quadrant has range of angles from 270 degrees to 360 degrees.
Since the given angle measures 130°, thus its plot has initial side on zero degree and terminal side on 130° in the second quadrant, as [tex]90^{\circ}< 360^{\circ} < 180^{\circ}[/tex]
Thus, we have terminal side of a 130° angle lying in the second quadrant.
