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.

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]

This satisfies the given volume so it could be the correct answer.

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

The sum of all positive values of x such that x² + 6x - 91 = 0 is 20

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

Using the slope concept, it is found that the base of the mirror will be 1.75 feet from the wall.

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.

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....

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°..

Answer:

(1,1), (2, 1/4), (3, 1/9), (4, 1/16)

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.

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.
