Answer:

42

Step-by-step explanation:

g(4) = 2x^2+5

= 2(4)^2+5

= 2(16)+5

= 32+5

= 37

f(g(4)) = 21+3sqrt(x+12)

= 21+3sqrt(37+12)

= 21+3sqrt(49)

= 21+3(7)

= 21+21

= 42

The circumference of a circle is 12.56 cm. What is the area? Use 3.14 for PI
tankabanditka [31]
Hola!

Circumference of circle is 12.56 cm
Means,

2 × π × r = 12.56

r = 12.56 × 3.14 × 2

r = 1.999 cm

According to Question,

Area of Circle:

π × r²

3.14 × 1.99 × 1.99

12.547 cm² = 12.56 cm² (approximately.)

Hence,
Area of Circle is 12.56 cm²

hope it helps!

2. State a price at which there would be a surplus of cort and explain why.
Annette [7]

A surplus exists when the price is above equilibrium, which encourages sellers to lower their prices to eliminate the surplus. A shortage will exist at any price below equilibrium, which leads to the price of the good increasing. For example, imagine the price of dragon repellent is currently $6 per can.

The length and width of a rectangle are given by f(x) = 3x2 – 2x and g(x) = 2x – 3, where x > 2. What is f ⋅ g and what does
EleoNora [17]

Answer:

C

Step-by-step explanation:

We are multiplying f(x) and g(x), which are the length and width. The area of a rectangle is a=l*w, so we can eliminate choice B.

Now, we have to find what f(x) * g(x) is

 f(x) * g(x)

f(x) is 3x^2-2x and g(x) is 2x-3, so we can substitute them in

(3x^2-2x)*(2x-3)

Use FOIL to find the answer

F: 3x^2*2x= 6x^3

O: 3x^2* -3 = -9x^2

I: -2x*2x= -4x^2

L: -2x*-3= 6x

6x^3-9x^2-4x^2+6x

Combine like terms

6x^3-13x^2+6x

So, we know that f(x) *g(x) is 6x^3-13x^2+6x, and that it is the area (l*w), so choice C is correct.
