Answer:

Base X = 10.82

Step-by-step explanation:

Given,

Perpendicular = 59°

Base = x

Hypotenuse = 17

Recall the SOHCAHTOA

Use sincose's formulae

Sin = Opposite/Hypotenuse

Sin59° = x/17

Solving for x,

17*sin59° = <em>x</em>
10.82 = x
x = 10.82

Base = 10.82

What is the area of the kite?

enot [183]

The area of the kite is 2.25 square feet

<h3>How to determine the area of the kite?</h3>

The area of the kite is calculated using:

Area = 0.5 * pq

Where p and q are the diagonals of the kite.

In this figure,

p = 3

q = 0.75 * 2 = 1.5

So, we have:

Area = 0.5 * 3 * 1.5

Evaluate

Area = 2.25

Hence, the area of the kite is 2.25

Find all solutions of the equation algebraically. Use a graphing utility to verify the solutions graphically. (Enter your answer

Anuta_ua [19.1K]

Answer:

The solutions of the equation are 0 and 0.75.

Step-by-step explanation:

Given : Equation $16x^4 - 24x^3 +9x^2 =0$

To find : All solutions of the equation algebraically. Use a graphing utility to verify the solutions graphically ?

Solution :

Equation $16x^4 - 24x^3 +9x^2 =0$

$x^2(16x^2-24x+9)=0$

Either $x^2=0$ or $16x^2-24x+9=0$

When $x^2=0$

$x=0$

When $16x^2-24x+9=0$

Solve by quadratic formula, $x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

$x=\frac{-(-24)\pm\sqrt{(-24)^2-4(16)(9)}}{2(16)}$

$x=\frac{24\pm\sqrt{0}}{32}$

$x=\frac{24}{32}$

$x=\frac{3}{4}$

$x=0.75$

The solutions of the equation are 0 and 0.75.

For verification,

In the graph where the curve cut x-axis is the solution of the equation.

Refer the attached figure below.
