Answer:

Divide 28 by 2

Step-by-step explanation:

When the variable of interest is multiplied by something, you undo that multiplication by dividing the equation by that something.

Here, l is multiplied by 2, so the solution is found by dividing ...

... 28 = l·2

by 2 to get ...

... 28/2 = l

That is, you divide 28 by 2 to find l.

Alina [70]

$390 is the interest will Charlie’s initial investment earn over the 15-year period. The money does Charlie have after the 15 years is $715.

<u>Step-by-step explanation:</u>

Harlie invests $325 in an account.

  • Principal, P = $325
  • Interest rate, r = 8% ⇒ 0.08
  • Number of years, t = 15

<u>The formula to find the interest will Charlie’s initial investment earn over the 15-year period :</u>

⇒ I = Prt<u></u>

⇒ 325\times 0.08\times15

⇒ 390

Therefore, $390 is the interest will Charlie’s initial investment earn over the 15-year period.

<u>Money Charlie has after 15 years :</u>

It is given by the formula,

⇒ Amount = Principal + Interest.

⇒ 325 + 390

⇒ 715 dollars.

∴ The money does Charlie have after the 15 years is $715.

Answer: 15

Step-by-step explanation:

Lets name the missing point as "x"

8^2 + x^2 = 17^2

=> 64 + x^2 = 289

=> x^2 = 289 - 64

=> x^2 = 225

=> x = 15

Radda [10]

For f(t) = 3 sin(t), the minimum is -3, the maximum is 3.

For additional information:

The  period T of the function y=3sin(4t) is;

The period of y = 3 sin (4t) is (2pi) / 4 = pi / 2

The sine function with amplitude A = 0.75 and period T = 10, is

y = 0.75 sin( (2pi / 10) x )

= 0.75 sin( (pi/5) t)

y(4) = 0.75 sin( (pi/5) (4) )

= 0.75 sin ( (4/5) pi ) = .4408

Drawing the sine and cosine function on the same plot shows

that they are identical except for a horizontal shift.

The cosine

function leads the sine function by a shift of (2pi/4) = pi/2.

For the last part, y(4) = 0.75 cos( (2pi/10) (4) ) = - 0.6067
