Answer:

24m and 25m.

Step-by-step explanation:

By Pythagoras Theorem:

h^2 = x^2 + 7 ^2 where h is the hypotenuse and x is the other leg.

But x and h are consecutive integers

so h = x + 1 and:

(x + 1)^2 = x^2 + 49

x^2 + 2x + 1 - x^2 = 49

2x + 1 = 49

2x = 48

x = 24

So the 2 lengths are 24 and 25.

Explain how to graph a piecewise function

tester [92]

<span>Just graph the function up to and/or including the points indicated.

- if you have a piecewise function defined as y=x when x < 0
y=-x when x >=1

You would graph y=x from the negative direction up to 0 (but leaving an open circle on 0 because the function is not defined there

Then start at point 1 (this time with a closed circle because y=-x is defined at 1, and graph y=-x.</span>

Lori buys a $586 certificate of deposit (CD) that earns 6.6% interest that compounds monthly. How much will the CD be worth in 1

Alex777 [14]

Answer:

Step-by-step explanation:

This problem can be solved using the compound interest formula

$A= P(1+r)^t$

Given data

A, final amount =?

P, principal = $586

rate, r= 6.6% = 0.066

Time, t= 13 years

Substituting our values into the expression we have

$A= 586(1+0.066)^1^3\\\ A= 586*(1.066)^13\\\ A= 586*2.295\\\ A= 1344.87$

To the nearest cent the in 13 years the CD will be worth $1344.9
