Answer:

No, It is not a right triangle

Step-by-step explanation:

For it to be a right triangle, the hypotenuse would be equal to the sum of the legs when squared.

Use the pythagorean theorem-

8^2+12^2=15^2

64+144=225

208=225

Since they aren't equal, it is not a right triangle.

Step-by-step explanation:

Move it it up 4 and then find your x intercepts.

Find the x intercepts.

$-x^2 + 4 = 0$

<u>Move the 4 over to the right</u>

$-x^2 = -4$

<u>Divide out the - </u>

$\frac{-x^2}{-} = \frac{-4}{-}$

$x^2 = 4$

<u>Take the square root of each side</u>

$\sqrt{x^2} = \pm \sqrt{4}$

$x = \pm \sqrt 2$

Our x intercepts are at (-2,0) (2,0)

An account has $26,000 after 15 years. The account received 2.3 percent interest compounded continuously. How much was deposited

Leya [2.2K]

The intital amount deposited was $18485.82.

<h3>How to find the compound interest?</h3>

If n is the number of times the interested is compounded each year, and 'r' is the rate of compound interest annually, then the final amount after 't' years would be:

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

An account has $26,000 after 15 years. The account received 2.3 percent interest compounded continuously.

A = 26000

R = 0.02.3

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

$26000 = p(1 + \dfrac{2.3}{100})^{15}\\\\26000 = p \times 1.4064\\\\\P= 18485.82$

Therefore, the intital amount deposited was $18485.82.
