since we are dealing with composite figures, we need to find the anwser to each shape.

<h3>Rectangle</h3>

A = 16 x 6 = 96

<h3>Square</h3>

Since we do not have an exact length, we have to find the <em>difference (subtraction). </em>14, bottom length of composite figure, minus 6 (length of rectangle) equals 8.

Now, you can use this process for the width. 16, width of shape, 2 half-width of rectangle, equals 14.

A = 8 x 14 = 112

So, 112 + 96 = 208 is your anwser

What is the correct answer..

solong [7]

Answer:

64 feet

Step-by-step explanation:

To find the height of the kite we use sin trigonometric ratio.

Let the height of the kite from the ground be x feet.

$\therefore \: \sin 40 \degree = \frac{x}{100} \\ \\ \therefore \: 0.6427876097= \frac{x}{100} \\ \\ \therefore \: 0.6427876097 \times 100= x \\ \\ \therefore \:x = 64.29 \\ \\ \therefore \:x = 64 \: feet$

The answer is 8.72.

sqrt(76) = 2sqrt(19)
2sqrt(19) = 8.717797887
Rounded to nearest hundredth ≈ 8.72

Emily and Jasmine had the same number of stamps. After Emily gave 42 stamps to Jasmine, Jasmine had twice as many stamps as Emil

kirza4 [7]

There are 84 because if they have the same amount and when you add 42 it's doubled 42+42=84 84/2=42 so she will end up with 84

Lindsay is creating a bridge out of dried pasta and glue. In her plans, she sketches the graph to determine the lengths of the n

alexgriva [62]

From the graph shown it can be seen that the bridge is represented by a parabola with vertex of (5, 8) and roots of 1 and 9.

Recall that the vertex form of the equation of a parabola with vertex (h, k) is given by
$y=a(x-h)^2+k$

Thus, the equation of the given graph in vertex form is given by
$y=a(x-5)^2+8$

Also, recall that the equation of a parabola with roots, p and q, is given by
$y=a(x-p)(x-q)$

Thus the equation of the given graph can be given by
$y=a(x-1)(x-9)$

To get the value of a, we equate both equations and solve as follows:
$a(x-5)^2+8=a(x-1)(x-9) \\ \\ a(x^2-10x+25)+8=a(x^2-10x+9) \\ \\ ax^2-10ax+25a+8=ax^2-10ax+9a \\ \\ 25a-9a=-8 \\ \\ 16a=-8 \\ \\ a=- \frac{8}{16} =- \frac{1}{2}$

Therefore, the <span>function that Lindsay used to create her design is
$f(x)=-0.5(x-5)^2+8$
</span>
