Answer:

x=7.12

Step-by-step explanation:

This is a trigonometry problem so you would use sin cos or tan. and in this case we need to use sin.

An acronym I use to help me remember is is sohcahtoa

so sin= opposite / hypotenuse

and that means sin(22)= x/19

we then plug in sin (22) in out calculator and get around .37

then we can use algebra and multiply .37 by 19 to get our x value

.37(19)=x

x=7.12

Find the length of an arc made by a 180-degree central angle in a circle with a 10ft radius

mixas84 [53]

Answer:

the length of an arc = 10π ft.

Step-by-step explanation:

The length of an arc with angle Θ and radius r will be equal r * Θ

note the angle must be in radian

Given: Θ = 180° = π and radius = r = 10 ft.

So, the length of the arc = π * 10 = 10π ft.

Help Pre-Calc

Anna11 [10]

Answer:

Average rate of change = 2

Step-by-step explanation:

We need to find the average rate of change of f(x) over the interval [-4,-1], so first we need to find the end points at x=-4 and x=-1.

From graph we see that y=-3 when x=-4, So the point is (-4,-3)

From graph we see that y=3 when x=-1, So the point is (-1,3)

Now we can plug these points into average rate of change formula:

$Average\ rate=\frac{f\left(b\right)-f\left(a\right)}{b-a}$

where (a,f(a)) and (b,f(b)) are the given points.

$Average\ rate=\frac{-3-3}{-4-\left(-1\right)}$

$Average\ rate=\frac{-3-3}{-4+1}$

$Average\ rate=\frac{-6}{-3}$

$Average\ rate=2$

Hence final answer is 2.
