Answer:

True Statement are

\sin E =\dfrac{11}{\sqrt{185}}

\sin D =\dfrac{8}{\sqrt{185}}

Step-by-step explanation:

Given:

DF = 11

EF = 8

DE = \sqrt{185}=Hypotenuse

In Right Angle Triangle DEF, the Sine Identity is

\sin D = \dfrac{\textrm{side opposite to angle D}}{Hypotenuse}\\

Substituting the values we get

\sin D = \dfrac{EF}{DE}=\dfrac{8}{\sqrt{185}}

\sin D =\dfrac{8}{\sqrt{185}} ....True

And also,

\sin E = \dfrac{\textrm{side opposite to angle E}}{Hypotenuse}\\

Substituting the values we get

\sin E = \dfrac{DF}{DE}=\dfrac{11}{\sqrt{185}}

\sin E =\dfrac{11}{\sqrt{185}} ....True

How much would $200 invested at 7% interest compounded annually be worth after 5 years? Round your answer to the nearest cent. D
viktelen [127]
The future worth (F) of the investment at present (P) with a compound interest i after n years is calculated through the equation,
                                      F = P x (1 + i)^n
Substituting the known values,
                                      F = ($200) x (1 + 0.07)^5 = $280.51
Thus, the future worth of the investment is approximately $280.51.

What two numbers' sum=-4 and product=-2
n200080 [17]

Let <em>a</em> and <em>b</em> be the two numbers. Then

<em>a</em> + <em>b</em> = -4

<em>a b</em> = -2

Solve the second equation for <em>b</em> :

<em>b</em> = -2/<em>a</em>

Substitute this into the first equation:

<em>a</em> - 2/<em>a</em> = -4

Multiply both sides by <em>a</em> :

<em>a</em>² - 2 = -4<em>a</em>

Move 4<em>a</em> to the left side:

<em>a</em>² + 4<em>a</em> - 2 = 0

Use the quadratic formula to solve for <em>a</em> :

<em>a</em> = (-4 ± √(4² - 4(-2))) / 2

<em>a</em> = -2 ± √6

If <em>a</em> = -2 + √6, then

-2 + √6 + <em>b</em> = -4

<em>b</em> = -2 - √6

In the other case, we end up with the same numbers, but <em>a</em> and <em>b</em> are swapped.

If f(x) = 2x + 1 and g(x) = x2 + 5,<br> what is g(f(2))?
Amiraneli [1.4K]

Answer:

30 if that is an x^{2} in g(x)

Step-by-step explanation:

f(2) = 2x + 1

      = 2(2) + 1

      = 4 + 1

f(2) = 5      

g(5) = x^{2} + 5

      = 5^{2} + 5

      = 25 + 5

g(5) = 30
