That means f(x)=kx²
so
f(5)=75=5²k
solve for k
75=5²k
75=25k
divide by 25
3=k
f(x)=3x² is da equation
so
f(4)=3(4)²
f(4)=3(16)
f(4)=48

Step-by-step explanation:
The area of the city park will be equal to 3952 square units.
<h3>What is the area?</h3>
The Area is defined as the space occupied by the two-dimensional geometry in a plane.
We have the following information:-
In City Park, the playground takes up 3/8 of the area:-
The soccer field area is 1/3 of the playground area.
The product 13×38 can be used to find the area of the soccer field
SF= 13 x 38=494 square units
Noe the PGA will be:-
PGA =3 x SF
PGA= 3 x494=1482 square unit
Now the area of the city park will be calculated as:-
CP=3952 square unit
Hence the area of the city park will be equal to 3952 square units.

Answer:
a = 3/2 b
When we simplify 3/2, we get 1.5
a = 1.5b
Step-by-step explanation:
The given equation 7a - 2b = 5a + b
Isolate the variables.
Subtract 5a from both sides, we get
7a - 5a - 2b = 5a - 5a + b
2a - 2b = b
Now add 2b from both sides, we get
2a - 2b + 2b = b + 2b
2a = 3b
Dividing both sides by 2, we get
a = 3/2 b
Hope this will helpful.
