C. 48.9663'
Help!! I don’t know
Answer:
63 = x
Step-by-step explanation:
We know that a triangle's angles always add up to 180º. Since Line DC is a 180º line, we can subtract 128 from 180.
180 - 128 = 52º
The angle next to A is 52º.
Then, we add 52 and 65 to get the sum of the two angles.
52 + 65 = 117
Finally, subtract 117 from 180 to get our x.
180 - 117 = 63
x = 63
To check, add all the angle values together and if they equal to 180, your answer is correct.
63 + 52 + 65 = 180. Correct!
=======================================
Explanation:
Through the remote interior angle theorem, adding the remote interior angles x and 65 results in the exterior angle 128. Note how the exterior angle is not adjacent to any of the interior angles (which is where the "remote" portion comes from).
x+65 = 128
x+65-65 = 128-65
x = 63
------------------
A longer method involves finding interior angle BAC using the given exterior angle
angle BAC = 180-(exterior angle DAB)
angle BAC = 180-128
angle BAC = 52
So far, the triangle BAC has two known interior angles 65 and 52. The missing angle x adds onto the previous two getting us 180
x+65+52 = 180
x+117 = 180
x = 180-117
x = 63
We get to the same x value.
Find the distance between the points (0, 2) and (-9, -10).
Answer:
15
Step-by-step explanation:
OPTION 1:
We can use the distance formula to find the distance between these two points.
[tex]\sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}[/tex]
X2 is -9, X1 is 0, Y2 is -10, and Y1 is 2, so we can substitute inside the equation.
[tex]\sqrt{(-9-0)^2 + (-10-2)^2}\\\\\sqrt{9^2 + -12^2}\\\\\sqrt{81 + 144}\\\\\sqrt{225}\\\\15[/tex]
OPTION 2:
We can look at the change in x and the change in y and use the Pythagorean Theorem to find the missing length of the hypotenuse.
The x changes by 9, and the Y changes by 12.
[tex]a^2+b^2=c^2[/tex] is the Pythagorean Theorem. We know a and b, so we can substitute inside the equation.
[tex]9^2 + 12^2 = c^2\\\\81+144=c^2\\\\225=c^2\\\\c=15[/tex]
Hope this helped!
Answer: The distance is 15 units.
Step-by-step explanation:
Find the difference in the x and y coordinates and square them and add them together.
(0,2) and (-9,-10) The x coordinates are 0 and -9 and the y coordinates are 2 and -10.
0-(-9) = 9
2-(-10) = 12
9^2 + 12^2 = d^2
81 + 144 = d^2
225 = d^2
d = [tex]\sqrt{225}[/tex]
d= 15

The engineers who designed an arch used the function h(x) = -0.005061x^2 + 0.499015x to describe the height of the arch (h) a distance of x from each end. Determine the distance between the ends of the arch, and the height of the arch.
Answer:
1) The distance between the ends of the arch is approximately 98.6
2) The eight of the arc is approximately 12.3
Step-by-step explanation:
1) The function for the height of the arch, h(x) = -0.005061·x² + 0.499015·x
Where;
x = The distance from the ends of the arch = 0, which gives;
0 = -0.005061·x² + 0.499015·x
Factorizing the above equation, we get;
0 = x·(-0.005061·x + 0.499015)
Which gives;
x = 0 or (-0.005061·x + 0.499015) = 0
-0.005061·x + 0.499015 = 0 gives;
-0.005061·x = -0.499015
x = -0.499015/(-0.005061) ≈ 98.6
Therefore, the height of the arch is zero at distance x = 0 and x = 98.6
Which gives the distance between the ends of the arch = 98.6
2) The height of the arc function h(x) = -0.005061·x² + 0.499015·x, whereby the coefficient of x² is negative, shows that it is ∩-shaped, the coordinates height and therefore, the height, is given by equating the derivative of the function to zero as follows;
d(h(x))/dt = d(-0.005061·x² + 0.499015·x)/dt = 2×(-0.005061)×x + 0.499015
d(h(x))/dt = 0 gives;
2×(-0.005061)×x + 0.499015 = 0
x = -0.499015/(2×(-0.005061)) ≈ 49.3
Therefore, the height of the arc, is the height at the point where x = 49.3
Therefore, we find the height of the arc from the height equation as follows;
h(x) = -0.005061×(49.3)² + 0.499015×49.3 ≈ 12.3
The eight of the arc is approximately 12.3.
Square root of 4489 by division method
Consider first two digits and then the next two digits.If there are three digits in the given number then first consider the first digit and then the take two digits together
6 | 4489 | 6x
36
12x | 889 |
Now the number 889 has 9 in units place so take a share number which has 9 at the end (ex.3*3=9 and 7*7=49)
So put 7 in the place of x and multiply the x value with 12x(that is 127) u will get the remainder as 0
Therefore the square root of 4489 is 6x*6x i.e. 67*67=4489

Find the limit of the function by using direct substitution. Limit as x approaches zero of quantity x squared plus ten. Answer Choices: A) -10 B) Does not exist C) 0 D) 10
Answer:
D
Step-by-step explanation:
So we are given the limit:
[tex]\lim_{x \to 0} (x^2+10)[/tex]
To figure out this limit, we can use direct substitution. Simply substitute 0 for x and then simplify. Therefore:
[tex]\lim_{x \to 0} (x^2+10)\\=(0)^2+10\\=0+10\\=10[/tex]
Therefore, the limit equals 10.
find the equation of the line perpendicular to the line x=9 that passes through the point (9,-1)
Answer:
y = -1
Step-by-step explanation:
Notice that the line x = 9 is a vertical line, therefore a line perpendicular to it will be a horizontal line of the form y = constant number.
Since we want it to go through the point (9, -1), then we know that that y value needs to be "-1", and the equation of the line will be given by the expression:
y = -1
Answer:
y =1
Step-by-step explanation:
[tex](9,-1)=(x ,y)\\\\x =m_1 =9\\m_2 = \frac{-1}{m_1} = \frac{-1}{9} = -\frac{1}{9} \\\\Substitute \:the \:values\:into ;\\y =mx+b\\\\-1 =-\frac{1}{9} (9) +b\\-1 = -1+b\\-1+1 = b\\0 =b\\m= 1 \\Substitute\:the\:new\:values\:into ;\\y = mx+b\\y = 1 x +0\\ y= 1[/tex]
The area of a rectangle is 180 square centimeters. If the length of the rectangle is 15 cm, what is its width?
Answer:
[tex]width=12[/tex]
Step-by-step explanation:
The formula for the area of a rectangle:
[tex]Area=length*width[/tex]
Insert the known values:
[tex]180=15w[/tex]
Solve for w. Isolate the variable by dividing both sides by 15:
[tex]\frac{180}{15}=\frac{15w}{15} \\\\12=w[/tex]
w is equal to 12, so the width of the rectangle is 12 cm.

Given the geometric series:
[tex]\{\dfrac{1}2, -1, 2, -4, ..... \}[/tex]
To find:
Sum of series upto 5 terms using the geometric series formula = ?
Solution:
Formula for sum of a n terms of a geometric series is given as:
[tex]S_n=\dfrac{a(1-r^n)}{1-r} \ \{r<1 \}[/tex]
[tex]a[/tex] is the first term of the geometric series
[tex]r[/tex] is the common ratio between each term (2nd term divided by 1st term or 3rd term divided by 2nd term ..... ).
Here:
[tex]a = \dfrac{1}{2}[/tex]
[tex]r = \dfrac{-1}{\dfrac{1}{2}} = -2[/tex]
[tex]n=5[/tex]
So, applying the formula for given values:
[tex]S_5=\dfrac{\dfrac{1}2(1-(-2)^5)}{1-(-2)} \\\Rightarrow S_5=\dfrac{1-(-32)}{2 \times 3} \\\Rightarrow S_5=\dfrac{1+32}{6} \\\Rightarrow S_5=\dfrac{33}{6} \\\Rightarrow \bold{S_5=\dfrac{11}{2}}[/tex]
So, the answer is

The perimeter of a rectangle can be found using the equation P=2L + 2W , where P is the perimeter, L is the length, and W is the width of the rectangle. Can the perimeter of the rectangle be 60 units when its 11 units and its length is 24 units?
Step-by-step explanation:
From the question
Perimeter = 2L + 2W
L = 24 units
W = 11 units
Substitute the values into the above formula
That's
P = 2(24) + 2(11)
P = 48 + 22
P = 70 units
Therefore the perimeter of the rectangle cannot be 60 units since the values when substituted into the above formula will give us 70 units

A shopkeeper gained Rs 8 by selling a pen by allowing 10% discount. Hw would have gained Rs 20, if he had not allowed discount. What was the cost price of the pen?
Answer:
Cost of the pen = Rs.100
Step-by-step explanation:
Let the marked price = x
When the shopkeeper is selling for x, his gain = Rs. 20
Cost price = Marked price - Gain = x - 20 --------(I)
After discount:
Discount = 10%
Marked price after discount = (100 - 10)% of x = 90% of x
= 0.9 * x = 0.9x
When the shopkeeper is selling for 0.9x, his gain = Rs.8
Cost price = Marked price - gain = 0.9x - 8 -------(II)
From (I) and (II)
x - 20 = 0.9x - 8
x = 0.9x - 8 + 20
x = 0.9x + 12
x - 0.9x = 12
0.1x = 12
x = 12/0.1
x = 120
Marked price of pen = Rs.120
Cost price = 120 - 20
Cost price = Rs. 100

Simplify the following expression. (3m/4-2)+8
A. 8m/4
B. 9m/4
C. 3m+24/4
D. 3m+28/4
Answer:
C. 3m+24/4
Step-by-step explanation:
Given that (3m/4 - 2) + 8
Then we solve
= (3m/4 - 8/4) + 8
= (3m - 8)/4 + 32/4
= (3m - 8 + 32)/4
= 3m + 24 /4
Therefore the answer is C
Alternatively, we can simplify the equation by
Given that, the equation is ( 3m/4 - 2 ) + 8
We then remove parenthesis
= 3m/4 - 2 + 8
= 3m/4 + 6
= 3m/4 + 24/4
Then add the numerators and leave the denominator
= 3m + 24 /4
This also equals option C.
Hence, it can be concluded that, the correct answer is Option C: (3m + 24)/4

Please help what is domain of f?
Answer:
In domain: -2.
Not in domain: 2, 4.
Step-by-step explanation:
The domain of a square root function is all real numbers such that the expression under the square root is greater than or equal to 0.
So, set the expression under the square root greater than or equal to 0 and solve for x:
[tex]-2x\geq 0\\[/tex]
Divide both sides by -2. When dividing by a negative, we flip the sign:
[tex]x\leq 0[/tex]
So, the domain of the function is all real numbers such that x is greater than of less than 0.
-2 is less than 0. So, it is in the domain.
2 is not less than 0. So, it is not in the domain.
4 is not less than 0. So, it is also not in the domain.
