Answer:

  x = 64 m

Step-by-step explanation:

The scale is proportional to the actual:

  (6 m)/(3/4 cm) = x/(8 cm)

Multiplying by 8 cm, we get ...

  x = (8 cm)·(6 m)/(3/4 cm)

  x = 64 m . . . . the width of the actual wall

Answer:

The wall is ninety meters wide.

Step-by-step explanation:

Set up and solve a proportion to find the value of w

Cancel out the like units on both sides of the equation.

Equate the cross-products, and then solve for w.

The actual width of the wall is ninety meters.

Part A:

If (7^2)^x = 1 then the value of x is equal 0

Because when x = 0 the

(7^2)^0 = 1 ; 7^0 = 1

Any number with 0 exponent is always equal 0, except 0.


Part B:

If (7^0)^x = 1, then the value of x is all real number

Because when 0 multiplies any number, it is always equal 0. So then 7^0 is always equal 1.

Example

if x = 1 then (7^0)^1 = 7^0 = 1

if x = -1 then (7^0)^(-1) = 7^0 = 1

if x = 1000 then (7^0)^(1000) = 7^0 = 1

Problem 4

Answer: 47

------------------------

Work Shown:

f(x) = x^2 - 7x + 3
f(x) = (x)^2 - 7(x) + 3
f(-4) = (-4)^2 - 7(-4) + 3 ... replace each x with -4
f(-4) = 16 - 7(-4) + 3
f(-4) = 16 + 28 + 3
f(-4) = 44 + 3
f(-4) = 47

============================================================

Problem 5

Answer: See the attached image for the table

------------------------

Work Shown:

Plug in n = 27 and we get...
C = 26 + 10*n
C = 26 + 10*27
C = 26 + 270
C = 296
The input n = 27 leads to the output C = 296. This means that 27 people will have the cost be $296

Do the same for n = 39
C = 26 + 10*n
C = 26 + 10*39
C = 26 + 390
C = 416
The input n = 39 leads to the output C = 416. This means that 39 people will have the cost be $416

and also n = 43 as well
C = 26 + 10*n
C = 26 + 10*43
C = 26 + 430
C = 456
The input n = 43 leads to the output C = 456. This means that 43 people will have the cost be $456
