Answer:
f= 5k-2/-k+2
Step-by-step explanation:
The expression will be given as h(8) = -0.3(8-5)²+7.5 the value of the function h(8) will be 6.3 feet.
<h3>What is an expression?</h3>
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Given that:-
- The function is h(x) = -0.3( x - 8)² +7.5
Now from the question when the boy jumped from a certain height he lands 8 feet farther away this condition will be expressed in the expression as follows:-
h(x) = -0.3( x - 8)² +7.5
Put x = 8 feet as
h(8) = -0.3(8-5)²+7.5
h(8) = -0.3 ( 3 )² + 7.5
h(8) = -2.7 + 9
h( 8 ) = 6.3 feet
Therefore expression will be given as h(8) = -0.3(8-5)²+7.5 the value of the function h(8) will be 6.3 feet.
