This means an initial fee of $45 have to be paid to the provider and a charge of $35 per month.
<h3>
Linear equation</h3>
A linear equation is in the form:
y = mx + b
Where y, x are variables, m is the rate of change and b is the initial value of y.
Let S represent the total cost of service for x months. Given:
y = 35x + 45
This means an initial fee of $45 have to be paid to the provider and a charge of $35 per month.

26.34 I believe is the correct answer
Answer:
18 seconds
Step-by-step explanation:
according to the question
-16t²+5184=0 (0 because when the height is 0 the ball will hit the ground)
-16t²=-5184
t²=-5184/-16
t²=324
t=√324
t=18
Answer:
a) The maximum amount of water the aquarium can hold is 1728 in³.
b) The cover has to be 624 in² big.
Step-by-step explanation:
a) The maximum volume of water that the aquarium can have is the same as the volume of the aquarium:
V=L×W×H=18 in × 8 in × 12 in= 1728 in³
b) The protective covering is used on the four walls of the aquarium. We have to find the areas of the four walls:
One of them is given by the multiplication of the width and the height:
A₁= W×H= 8 in × 12 in=96 in²
The other area is given by the multiplication of the length and the height:
A₂= L×H= 18 in × 12 in= 216 in²
As the fish aquarium is rectangular the area of the walls is given by:
=2×96 in²+2×216 in²=624 in²
