For the scale factor, use the dimensions from similar sides:

Using 18 from the original image you would use 6 from the scaled image.

18 /6 = 3

This means the scaled image is 3 times smaller than the original. Because the scaled image is smaller divide 1 by the scale factor to get 1/3.

Q2:

The scale factor is 1 inch = 12 miles.

Multiply the total inches by 12:

6.5 x 12 = 78 miles.

If f(x) = 4x - 3 and g(x) = x + 4, find (f - g)(x).
aleksandrvk [35]

Answer:

(f - g)(x) = 3x - 7

Step-by-step explanation:

(f - g)(x) = f(x) - g(x)

             = 4x - 3 - ( x + 4 )

             = 4x - 3 - x - 4

             = 3x -7

Solve using the quadratic formula. Show all work. Write each solution in simplest form. No decimals.
vagabundo [1.1K]

Answer:

A) -2 - i√3 , -2 + i√3

Step-by-step explanation:

Solve using quadratic formula

x² + 4x + 7 = 0

The Almighty Formula

= -b ± √b² - 4ac/2a

Where ax + bx² + c = 0

From the above question

a = 1, b = 4, c= 7

Hence,

-4 ± √4² - 4 × 1 × 7/2 × 1

-4 ± √16 - 28/2

=( -4 ± √-12)/2

Since

b² - 4ac < 0

We have two complex roots

Simplifying

( -4 ± √-12)/2

= -4/2 ± √-12/2

= -2 ± 2√3i/2

= -2 ± √3i

Therefore,

-2 - √3i , -2 + √3i

or

-2 - i√3 , -2 + i√3

Option A , is the correct answer

Write a linear cost function for the situation. Identify all variables used. A parking garage charges 4 dollars plus 65 cents pe
Liono4ka [1.6K]

Answer:

The linear cost function is C(x)=1.3x+4 dollar.

Step-by-step explanation:

Given : A parking garage charges 4 dollars plus 65 cents per half-hour. A linear cost function for the situation is C(x)=L.

To find : Write a linear cost function for the situation ?

Solution :

Cost function is defined as sum of marginal cost and fixed cost.

Let x be the number of hours i.e. time for which parking cost.

A parking garage charges 4 dollars plus 65 cents per half-hour.

The fixed price is $4.

Marginal cost is 65 cents per half-hour.

Converting cents into dollar,

1 cent = 0.01 dollar

65 cent = 0.65 dollar

The cost of \frac{1}{2} hour = $0.65

The cost of x hours = 0.65\times 2x

So, marginal cost is $1.3x.

Cost function is defined as

C(x)=MC+FC

C(x)=1.3x+4

C(x)=1.3x+4 dollar.

Therefore, The linear cost function is C(x)=1.3x+4 dollar where x is the number of hours.
