Complete Question

In ΔVWX, w = 780 cm, ∠X =21° and ∠W=146°. Find the length of x, to the nearest 10th of a centimeter.

Answer:

499.9cm

Step-by-step explanation:

We solve for length x using the Sine rule

w/ sin W = x /sin X

Cross Multiply

x × sin W = w × sin X

x = w × sin X/ sin W

x = 780 × sin 21°/ sin 146°

x = 499.88 cm

Approximately to nearest tenth = 499.9cm

A baseball player swings and hits a pop fly straight up in air to the catcher. the height of the baseball in meters t seconds af

Ludmilka [50]

$h(t)=-4.9t^{2}+34.3t+1
\\h'(t)=(-4.9t^{2}+34.3t+1)'=-9.8t+34.3
\\h'(t)=0
\\-9.8t+34.3=0
\\
\\t= \frac{34.3}{9.8} =3.5
\\
\\h_{max}=h(3.5)=-4.9\times3.5^{2}+34.3\times3.5+1=61.025$

The ball reaches its maximum height after 3.5 seconds, and the maximum height is 61.025 meters.

Burka [1]

Find fog

fog(x)
f(g(x))
f(√x-5)
2√(x-5)+3

For real range the domain

x-5≥0
x≥5

Domain is [5,oo)

Rufina [12.5K]

Answer:

x = $\frac{31}{3}$

Step-by-step explanation:

Given

3(x - 6) = 6 + 7, that is

3(x - 6) = 13 ← distribute parenthesis on the left side by 3

3x - 18 = 13 ( add 18 to both sides )

3x = 31 ( divide both sides by 3 )

x = $\frac{31}{3}$
