Answer:

a) is correct

b) y = -a(x - 2.5)² + h

(5.5,0)

0 = -a(5.5-2.5)² + h

h = 9a

a = h/9

48 = -a(0-2.5)² + h

h = 48 + 6.25a

h = 48 + 6.25(h/9)

h = 157.0909090681

Range: [0,157]

c) (80-144)/(4.5-3)

= -42⅔ or -42.67

What is the solution to the open sentence 18 = c + 6?

sveticcg [70]

This is very simple, all you have to do is subtract 18 and 6 and that would be 12, and now we have 12 as a POSSIBLE answer, lets check our work to be 100% correct so now try to add 12 and 6 and we get 18, so yay it made the equation true and since its true its right so that's the answer.

Answer: c = 12 so 18 = 12 + 6 is true.

Albert deposits $2785 in an account that earns 3.9% interest compounded monthly. this function models the amount in the account

Step2247 [10]

The amount for the given data is found as, $\rm a = 2825(1+\frac{3.9}{12} )^{12t}$ .The given expression is true.

<h3>What is the amount?</h3>

The complete repayment of money at the end of the period for which it was borrowed is referred to as the amount.

The given data in the problem is;

P is the annual payment=2827

r is the rate of interest = 3.9%

n is the time period=12

The formula for the amount is found as;

$\rm a = p(1+\frac{r}{n} )^{nt}$

Substitute the given value;

$\rm a = 2825(1+\frac{3.9}{12} )^{12t}$

Hence the given expression is true.
