To find the angle, we must subject ourselves to using trigonometric identities.

We know that in the triangle the ladder forms, we have the side opposite the angle and the hypotenuse.

The trigonometric formula that utilizes the information we have to the maximum is the sine function.

$sin(x) = \frac{15}{17} \\x = 61.9$ degrees

Thus the angle of elevation is 61.9 degrees

Hope that helped!

Answer:

$\sf x = 61.9^{\circ \:}$

<u>given</u>:

opposite side = 15

hypotenuse side = 17

<u>using sine rule</u>:

$\sf sin(x) = \dfrac{opposite}{hypotenuse}$

$\sf sin(x) = \dfrac{15}{17}$

$\sf x = sin^{-1}(\dfrac{15}{17} )$

$\sf x = 61.9^{\circ \:}$

Paul bought a 15-year treasury bond for a face amount of $600. The 2.5% interest will be compounded quarterly. What will the fut

Alika [10]

First, we convert the interest such that it is compounded annually. The formula would be:

ieff = (1 + i/m)^m - 1
where m = 4, since there are 4 quarters in a year
ieff = (1 + 0.025/4)^4 - 1
ieff = 0.0252

Then we use this for this equation:
F = P(1 + i)^n, where F is the future worth, P is the present worth and n is the number of years
F = $600(1 + 0.0252)^15
F = $871.53

Find the height of the prism if the length is 9 inches, the width is 5 inches, and the volume of the prism is 315 cubic inches.

trasher [3.6K]

Answer:

Height of prism = 7 inches

Step-by-step explanation:

Let h be the height of prism.

Hence,

$h = \frac{vol \: of \: prism}{l \times w} \\ \\ = \frac{315}{9 \times 5} \\ \\ = \frac{315}{45} \\ \\ h= 7 \: inches$

THIS IS THE COMPLETE QUESTION

basketball player is shooting a basketball toward the net. The height, in feet, of the ball t seconds after the shot is modeled by the equation h = 6 + 30t – 16t2. Two-tenths of a second after the shot is launched, an opposing player leaps up to block the shot. The height of the shot blocker’s outstretched hands t seconds after he leaps is modeled by the equation h = 9 + 25t – 16t2. If the ball reaches the net 1.7 seconds after the shooter launches it, does the leaping player block the shot?

Yes, exactly 0.6 seconds after the shot is launched.

Yes, between 0.64 seconds and 0.65 seconds after the shot is launched

Yes, between 0.84 seconds and 0.85 seconds after the shot is launched.

No, the shot is not blocked.

Answer:

Yes, between 0.84 seconds and 0.85 seconds after the shot is launched.

Given that the

equation for shot block height h = 9 + 25t – 16t2.

equation for ball height h = 6 + 30t – 16t2.

From the question ,it can be deducted that the shot is made before two tenths of a second or 0.2seconds
