Use the function to find f(4)
f(x)=1/3•4^x

f(4) = 256/3

Step-by-step explanation:

f(x)=1/3*4^x

f(4) = 1/3 * 4 ^4

4^4=4*4*4*4 = 256

f(4) = 1/3 * 256

f(4) = 256/3

The value of f(4) = 85.33

Step-by-step explanation:

It is given a function f(x),

f(x) = (1/3) * 4^x

To find the value of f(4)

To find the value of f(4) we have to substitute 4 instead of x

f(x) =  (1/3) * 4^x

bstitute x = 4 we get,

f(4) =  (1/3) * 4^4

 = (1/3) *  256

 = 85.33

Therefore the value of f(4) = 85.33

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
