Answer:

Step-by-step explanation:

Right triangle trig. Super fun! We are given the vertex angle of 27 degrees. The side across from that angle is 4, and we are looking for the hypotenuse of the triangle. That is the trig ratio sin. sin of an angle is equal to the side opposite over the hypotenuse:

$sin(27)=\frac{4}{hyp}$ and, solving for hyp:

$hyp=\frac{4}{sin(27)}$ . Do that on your calculator in degree mode to get that the hypotenuse, side BD is 8.8 units.

Really need help on #15 please.

ollegr [7]

Step-by-step explanation:

Let's call L the length and W the width. The length is 10 feet longer than the width, so:

L = W + 10

The area is the length times width, so:

119 = LW

Substituting:

119 = (W + 10) W

119 = W² + 10W

0 = W² + 10W − 119

0 = (W + 17) (W − 7)

W = -17 or 7

Since W must be positive, W = 7.

L = W + 10

L = 17

The length and width are 17 feet and 7 feet, respectively.

Please help! I know its either B or D but im not sure how to tell

DENIUS [597]

Answer:

Step-by-step explanation:

To find the equation of g(x), we can substitute the point into each of the equations.

A. g(x) = (1/4x)^2

1 = (1/4 * 2)^2

1 = (1/2)^2

1 = 1/4

This statement is false, so this is not the equation.

B. g(x) = 1/2 * x^2

1 = 1/2 * (2)^2

1 = 1/2 * 4

1 = 2

This statement is false, so this is not the equation.

C. g(x) = 2x^2

1 = 2 * 2^2

1 = 2 * 4

1 = 8

This statement is false, so this is not the equation.

D. g(x) = (1/2x)^2.

1 = (1/2 * 2)^2

1 = 1^2

1 = 1

This statement is true, so this is your answer.

Hope this helps!

Please help me with this question.

Sav [38]

Answer:

-2; -7

Step-by-step explanation:

Hello, the graph is split in two lines, right?

Go to the first line at the left and move to the right until you reach the end of the line, which is for x = -1,

*** This is the meaning of x tending to

$(-1)^{-}$ ***

which value can you see for the y-axis? $\boxed{-2}$

Now, go to the second line at the right and move to the left until you reach the end of the line, which is for x = -1,

*** This is the meaning of x tending to

$(-1)^{+}$ ***

which value can you see for the y-axis?

$\boxed{-7}$

Thanks
