Answer:

No. It is an obtuse triangle.

Step-by-step explanation:

If c^2>a^2+b^2, then the triangle is obtuse. Since 24^2 + 7^2 is 625, and the square root of 625 is 25, that means 26>25. This proves that the triangle is obtuse.

wolverine [178]

Answer:

$S = P(1.08)^{t}$

Step-by-step explanation:

A $10,000 deposit at the bank will double in value in 9 years.

If the interest is r% and it is compounded each year, then we can write from the formula of compound interest that

$20000 = 10000(1 + \frac{r}{100})^{9}$

⇒ $2 = (1 + \frac{r}{100})^{9}$

⇒ $1 + \frac{r}{100} = 1.08$

⇒ r = 8%

Therefore, the formula for the accumulated amount t years after the investment is made will be

$S = P(1 + \frac{8}{100})^{t} = P(1.08)^{t}$

where, P is the invested principal and S is the accumulated sum. (Answer)

Stels [109]

Answer:

Sean can dive 275 feet after he takes 13 lessons.

Step-by-step explanation:

Since L means the number of lessons taken, we will have:

D = 20*13 + 15

D = 260 +15

D = 275
