If f(x) = x2 and g(x) = 3x + 1, then g(f(2))= ?
andreyandreev [35.5K]

Answer:

The value of g[f(2)] = 13

Step-by-step explanation:

Given functions:

f(x) = x²

g(x) = 3x + 1

Find:

The value of g[f(2)]

Computation:

f(x) = x²

By putting x = 2 in f(x)

f(x) = x²

f(2) = 2²

f(2) = 2 × 2

f(2) = 4

So the value of f(2) = 4

Value of  f(2) putting in g(x)

g(x) = 3x + 1

g(x) = 3x + 1

g[f(2)] = 3[f(2)] + 1

We know that f(2) = 4

So,

g[f(2)] = 3[f(2)] + 1

g[f(2)] = 3[4] + 1

g[f(2)] = 12 + 1

g[f(2)] = 13

The value of g[f(2)] = 13

What are the dimensions of the tabletop with the
DIA [1.3K]

Answer:

Dimensions of the tabletop is 2.8 cm × 2.8 cm.

Step-by-step explanation:

From the picture attached,

ABCD is a tabletop with leaves AEG, BEF, CFH and GDH.

Dimensions of the tabletop ABCD,

Length = AB

Width = BC

Coordinates of A → (1, 3)

Coordinates of B → (3, 5)

Coordinates of C → (5, 3)

Coordinates of D → (3, 1)

Length of segment = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

AB = \sqrt{(3-1)^2+(5-3)^2}

     = \sqrt{4+4}

     = 2\sqrt{2}

     ≈ 2.8 units

BC = \sqrt{(5-3)^2+(3-5)^2}

     = \sqrt{4+4}

     = 2\sqrt{2}

     = 2.8 units

Therefore, dimensions of the tabletop is 2.8 cm × 2.8 cm.

A ski resort has 18 inches of snow on the ground. The snow is falling at a rate of 4 inches per hour. Which type of functions be
UNO [17]

Answer:

Option B. Linear

y=4x+18

Step-by-step explanation:

Let

x----> the time in hours

y----> the total inches of snow on the ground

we know that

The function that best model this situation is the linear function

so

y=mx+b

In this problem

m=4\frac{in}{h}

b=18\ in ----> the y-intercept

substitute

y=4x+18
