Jason jumped off of a cliff into the ocean in Acapulco while vacationing with some friends. His height above ocean measured in f
lbvjy [14]

Answer:

480 feet.

Step-by-step explanation:

We are told that the function h(t)=-16t^2+16t+480 models Jason's height above ocean measured in feet as a function of time and t is the time in seconds from jumping off.

To find the height of cliff we need to substitute t=0 in our given function as at t=0 we will get Jason's height above ocean which is same as the height of the cliff.

Upon substituting t=0 in our function we will get,

h(0)=-16(0)^2+16*0+480

h(0)=-0+0+480

h(0)=480

Since, the function gives Jason's height above ocean in feet, therefore, the cliff was 480 feet high.

What is the base of the exponetim the function f(x)=3(3/8)^2 when the function f(x)=3
galina1969 [7]

Answer:

Depending on what the equation is (see below for options) answers are:

\frac{log1}{log\frac{3}{8}} = x or -1,1=x

Step-by-step explanation:

Two possibilities are present:

  • The base of an exponential function is the number raised to an exponent of x. f(x) = 3(3/8)^x. The base here is 3/8. To find when f(x) = 3, then substitute and solve. 3=3(\frac{3}{8})^x\\1=(\frac{3}{8})^x\\log 1 = log \frac{3}{8}^x\\\frac{log1}{log\frac{3}{8}} = x
  • If this is a quadratic function then it has a base of x. f(x) = 3(x)^2. To find when f(x) = 3 then substitute and solve. 3=3(x^2)\\1=x^2\\1,-1=x
