Answer:
a:90 b:90 c:42 d:48 e:132
Step-by-step explanation:
assuming the picture is accurate^^^
a = 90°
b = 90°
c = 42°
d = 48°
e = 132°
Step-by-step explanation:
Here as you can see c and 132° is vertically opposite to each other so it can be name as vertically opposite angle....
Vertically opposite angle are always equal to each other....e = 132°
Now....
here c and d are supplementary angle...
c + d = 180°
132° + d = 180°
d = 180° - 132°
d = 48°
Now...
b = 90° ( being vertically opposite angle )
Here a and b are supplementary angle ....
a + b = 180°
a = 180° - 90°
a = 90°
Now...
c + 138° = 180° ( supplementary angle )
c = 180° - 138°
c = 42°..

Step-by-step explanation:
(1,1/2)(2, 1/4), (3, 1/9), (4, 1/16) are the ordered pairs which could be generated by an exponential function.
What is a function?A relation is a function if it has only One y-value for each x-value.
An exponential function is a Mathematical function in the form f (x) = aˣ, where “x” is a variable and
a is a constant which is called the base of the function and it should be greater than 0.
We have to find the set of ordered pairs could be generated by an exponential function.
(1,1/2)(2, 1/4), (3, 1/9), (4, 1/16) represents the exponential function.
y=1/2ˣ
y=2⁻ˣ
Hence, (1,1/2)(2, 1/4), (3, 1/9), (4, 1/16) are the ordered pairs which could be generated by an exponential function.

When Adam sights the top of a 10-ft-high statue from 100 ft away, he finds an angle of elevation of 2.3°. When his friend Mark stands in the same location and sights the top of the same statue, he finds an angle of elevation of 2.6°. Assuming both boys measured correctly, which boy is taller? By how much?
Answer:
Adam's height - Mark's height =
[10 - 100tan (2.3)] - [10 - 100tan(2.6) ] =
≈ [5.96ft - 5.46 ft] =

Emergency pls help: tisha is moving into her first apartment and ordered a large mirror for her room from a catalog. the catalog says the mirror is 7 feet tall. if she leans the mirror against the wall at a 76 degree angle, how far away from the wall will its base be, to the nearest hundredth of a foot?
Using the slope concept, it is found that the base of the mirror will be 1.75 feet from the wall.
What is a slope?The slope is given by the vertical change divided by the horizontal change, and it's also the tangent of the angle of depression.
In this problem, the vertical change is of 7 ft, with an angle of 76º, and the distance is the horizontal distance, hence:
tan(76º) = 7/d
d = 7/tan(76º)
d = 1.75.

What is the sum of all positive values of x such that x^2 + 6x - 91 = 0?
Answer:
20
Step-by-step explanation:
x^2 + 6x - 91 = 0
or, x^2 + 13x - 7x -91=0
or, x(x-13) -7(x-13) =0
or, (x-13)(x-7)= 0
either,
x-13=0 ==> X= 13
x-7=0 ==> X = 7
sum of all positive values of x = 13 +7 = 20The sum of all positive values of x such that x² + 6x - 91 = 0 is 20
What is quadratic equation?A quadratic equation is a second-order polynomial equation in a single variable x , ax2+bx+c=0. with a ≠ 0 .
The given equation is x² + 6x - 91 = 0
x² + 13x - 7x -91=0
Take common terms
x(x-13) -7(x-13) =0
(x-13)(x-7)= 0
x-13=0
x= 13 and
x-7=0
x= 7
The two positive numbers are 13 and 7.
The sum of all positive values is 13 +7 = 20
Hence, the sum of all positive values of x such that x² + 6x - 91 = 0 is 20

Use the given values of n and p to find the minimum usual value μ- 20 and the maximum usual value μ+20. Round your answer to the nearest hundredth unless otherwise noted.
n=713, p= 4/5
Answer:
μ - 2σ = 549.04μ + 2σ = 591.76Step-by-step explanation:
Given the parameters of binomial distribution
n = 713, p = 4/5We need to find the mean μ and the standard deviation σ to calculate required values
Follow the steps below1. Find the mean
μ = n·p = 713*(4/5) = 570.42. Find the variance
σ² = np(1 - p) = 713*(4/5)*(1 - 4/5) = 114.083. Find the standard deviation
σ = √114.08 = 10.68 (rounded)Find the minimum usual value
μ - 2σ = 570.4 - 2*10.68 = 549.04Find the maximum usual value
μ + 2σ = 570.4 + 2*10.68 = 591.76Answer:

Carson needs to build a closed container out of sheet metal, but needs to minimize the amount of sheet metal used. The volume of Carson's container needs to be approximately 320 cubic Inches. Carson needs to select one of the following designs that meets his volume requirement, using the least amount of sheet metal. Which design should Carson choose? A. Rectangular prism with dimensions of 8 inches (in.), 8 in., and 5 in. B. Rectangular prism with dimensions of 10 in., 8 in., and 4 in. C. Cylinder with a radius of 5 in. and height of 5 in. D. Square pyramid with a base length of 10 in., height of 10 in, and slant height of approximately 14 in.
Carson needs to select one of the following designs that meet his volume requirement, using the least amount of sheet metal which is the first option. Rectangular prism with dimensions of 8 in, 8 in., and 5 in.
How to find the volume of a right rectangular prism?Suppose that the right rectangular prism in consideration be having its dimensions as 'a' units, 'b' units, and 'c' units, then its volume is given as:
[tex]V = a\times b \times c \: \: unit^3[/tex]
Carson needs to build a closed container out of sheet metal but needs to minimize the amount of sheet metal used.
The volume of Carson's container needs to be approximately 320 cubic Inches.
Carson needs to select one of the following designs that meets his volume requirement, using the least amount of sheet metal.
If we consider the Rectangular prism with dimensions of 8 inches (in.), 8 in., and 5 in.
Then the volume would be
[tex]V = 8 \times 8 \times 5\\\\V = 320[/tex]
