Find the value of X, rounded to the nearest tenth. <br> A. 31.8<br> B. 31.4<br> C. 10.3<br> D. 10.7
Alenkinab [10]

Answer:

B. 31.4

Step-by-step explanation:

To find x, the hypotenuse, we need to use sin because we have been given the <u>opposite</u> (the side opposite the angle 35°) and we need to work out the <u>hypotenuse</u> (the longest or <em>slanted</em> side):

SOH, CAH, TOA

sin(θ) = opposite ÷ hypotenuse

Sub in the values (we don't know the hypotenuse so i've called it x):

sin(35) = 18 ÷ x (multiply both sides by x)

x × sin(35) = 18 (divide both sides by sin(35))

x = 18 ÷ sin(35) = 31.38204...

x ≈ 31.4

Hope this helps!

Determine the effects on the graph of the parent function ƒ(x) = x for the g(x) function.
love history [14]

Answer:

We can define a horizontal dilation/contraction of scale factor A, as:

g(x) = f(x*A)

if A > 1, this will be a contraction (it will be steeper)

if  0 < A < 1, this will be a dilation. (it will be less steep)

Then if we have:

g(x) = f(6*x) we have a contraction of scale factor 6, this means that the graph of the parent function will be contracted.

Below, you can see how the graphs change, where:

Blue is f(x)  =x

green is g(x) = f(6*x) = 6*x

Find the ratio of the area of triangle XBY to the area of triangle ABC for the given measurements, if BY = 3, YC = 2
Mazyrski [523]

Answer:

The ratio of the area of triangle XBY to the area of triangle ABC is \frac{9}{25}

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is equal to the scale factor and the ratio of its areas is equal to the scale factor squared

In this problem

Triangles XBY and ABC are similar, because the corresponding internal angles are congruent

see the attached figure to better understand the problem

step 1

Find the scale factor

Let

z-------> the scale factor

z=\frac{BY}{BC}

we have

BY=3\ units

BC=2+3=5\ units

substitute

z=\frac{3}{5}

step 2

Find the ratio of the area of triangle XBY to the area of triangle ABC

Remember that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

we have

z=\frac{3}{5} -----> scale factor

so

z^{2} =(\frac{3}{5})^{2} =\frac{9}{25}
