1 answer:

4 0

Answer: If there is no real solution, enter NO REAL SOLUTION.) Find all solutions of the equation and express them in the form x^3 − 2x^2 − 7x + 14 = 0. -separate the problem into factoring: x^3 and 2x^2 will be the outside numbers √(x + 42)=x ... Use f(x) = 4x − 3 and g(x) = 5 − x^2 to evaluate the expression. (f o g) (-2)

A kite with a string 80 feet long makes an angle of elevation of 40° with the ground, assuming the string is straight, how high

defon

The diagram of the kite is shown below

To find the perpendicular height of the kite from the ground, we use the trigonometry ratio for sin(x).

The reason for using the sine ratio is because we have the hypotenuse, 80 feet, and the angle, 40° and we are looking for the length of the side opposite the angle.

$sin(x)= \frac{opp}{hyp}$
$sin(40)= \frac{x}{80}$
$80sin(40)=x$
$x=51.42$ rounded to two decimal place

Perpendicular height of the kite from the ground is 51.42 feet

Solve for x.<br> -3 (x-1) + 8 (x-3) = 6x + 7 - 5x<br> Pls help as soon as possible thanks! :D

Answer:

x = 7

Step-by-step explanation:

-3 (x - 1) + 8 (x - 3) = 6x + 7 - 5x

-3 (x - 1) + 8 (x - 3) = 6x - 5x + 7

-3 (x - 1) + 8 (x - 3) = x + 7

-3x + 3 + 8x - 24 = x + 7

-3x + 8x + 3 - 24 = x + 7

5x - 21 = x + 7

+21 +21

--------------------------------------------------

5x = x + 28

-x -x

---------------------------------------------------

4x = 28
