A plant is already 13.50 meters tall, and it will grow 25 centimeters every month. the plants height H ( in meters), after x months is given H(x)=0.25x+13.50

what is the plants height after 30 months?

Step-by-step explanation:

Given the height of a plant that is already 13.50 meters tall and grows 25 centimeters every month modeled by  the equation  H(x)=0.25x+13.50,where x is the number of months. To find the plants height after 30 months, we will substitute x = 30 into the modeled equation as shown;

H(x)=0.25x+13.50

H(30)=0.25(30)+13.50

H(x)= 21.0

Hence the plants height after 30 months is 21.0metres

H(x)=7.5+13.50

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
