What is the area of the triangle shown below?

4.41

Step-by-step explanation:

To find the area of a triangle you need the base length and the height of the triangle

I used the Pythagorean theorem to find the height

I used 2.1 because the height will split the base in half

h=2.1

Now that we have the height you plug that into the Area formula

(4.2)(2.1)= 4.41

if you need just tell me and i will come to the rescue.

step-by-step explanation:

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
