Answer:
Step-by-step explanation:
When you multiply and irrational by a rational, you are doing nothing to change the nature of an irrational number. The two numbers have different kinds of properties and though a multiplication can be indicated, there is no way you can change the properties of an irrational number with a rational.
Their properties just do not mix.
It is like take a solvent and mixing it with something that is not a solvent. You cannot do anything to anything to the insolvent to make it solvent simply by adding more. Their properties remain in tact.
Take 3 * 4√7
The properties of the 3 and 4 remain the same when multiplied and they can be combined. 3*4 = 12
But nothing can be done with √7. The 3 cannot effect it, anymore than what the 4 did.
Answer:
A. because the product is always a non-terminating, non-repeating decimal.

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

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.
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.
Answer:
It’s C

Please solve 5x = 75
Answer:
x=15
Step-by-step explanation:
5x= 75 (divide)
75/5= 15
Answer: There is only one step to solve this equation; we use inverse operations to isolate the x by dividing 5 on both sides. We divide because 5 is being multiplied by x, and the inverse operation for multiplication is division.
5x/5 = x
75/5 = 15
The equation now looks like:
x = 15
x is equal to 15. This is your answer.
What is y=1/2x+4 in standard form?
===========================================
Explanation:
Multiply both sides by 2 to clear out the fraction
y = (1/2)x+4
2y = 2[ (1/2)x + 4 ]
2y = 2*(1/2)x + 2*4
2y = x + 8
Then move the x term over to the left side
2y = x+8
2y-x = 8
-x+2y = 8
Optionally we can multiply both sides by -1
-x+2y = 8
-1*(-x+2y) = -1*8
x-2y = -8
This is in standard form Ax+By = C with A = 1, B = -2, C = -8
The reason why I multiplied both sides by -1 was to make A > 0 which is what some textbooks use as convention. Of course -x+2y = 8 is equally valid too.

Answer:
40°, 95°, 105°, and 160°
Step-by-step explanation:
Let the smallest angle be x.
Measures of the 3 angles can be expressed as:
[tex] x + 55 [/tex]
[tex] x + 65 [/tex]
[tex] x + 120 [/tex]
The sum of all angles in a quadrilateral = 360°.
Therefore, [tex] (x + 55) + (x + 65) + (x + 120) = 360 [/tex]
Solve for x
[tex] x + 55 + x + 65 + x + 120 = 360 [/tex]
[tex] 3x + 240 = 360 [/tex]
[tex] 3x + 240 - 240 = 360 - 240 [/tex]
[tex] 3x = 120 [/tex]
[tex] \frac{3x}{3} = \frac{120}{3} [/tex]
[tex] x = 40 [/tex]
The smallest angle = 40°
Plug in the value of x in the earlier stated expressions to find the measure of the other angles:
[tex] x + 55 = 40 + 55 = 95 [/tex]
[tex] x + 65 = 40 + 65 = 105 [/tex]
[tex] x + 120 = 40 + 120 = 160 [/tex]

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

[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.

Janet wants to calculate the time it takes to earn a certain amount of
interest on a principal amount in an investment with simple interest. What
equation can she use?
Answer:
The time it takes to earn an amount A with a given principal P invested for a time period t is t = (A/P - 1)/r
Step-by-step explanation:
In order to calculate the time it would take to earn a certain amount of interest on a principal amount in an investment with simple interest, we use the simple interest formula as follows;
A = P·(1 + r·t)
A = The final amount after the number of periods of investment
P = The principal or initial amount
r = The interest rate per period
t = The number of the time periods
Therefore, the time it takes to earn a certain amount of interest on a principal amount in an investment with simple interest is fount by making t the subject of the above equation, which is given as follows;
A/P = 1 + rt
rt = A/P - 1
t = (A/P - 1)/r
Therefore, the time it takes to earn an amount A with a given principal P invested for a time period t is given by t = (A/P - 1)/r.
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 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
AC = 22, BC = x + 14, and AB = x + 10.
Find x.
Hi there! :)
Answer:
[tex]\huge\boxed{x = -1}[/tex]
Given:
AC = 22
BC = x + 14
AB + x + 10
AC is equivalent to AB + BC, therefore:
AC = AB + BC
Substitute in the expressions:
22 = (x + 10) + (x + 14)
Combine like terms:
22 = 2x + 24
Subtract 24 from both sides:
-2 = 2x
Divide both sides by 2:
x = -1
