Answer: About 14.14 in^3

Step-by-step explanation:

We know that the circumference of a sphere is C=2πr. We are given that the circumference is 9.42 in. We can find the radius to get our volume.

9.42=2\pi r

4.71=\pi r

r=1.5\\

Now that we know radius, we can find our volume.

V=\frac{4}{3} \pi r^3

V=\frac{4}{3} \pi (1.5)^3

V=14.14in^3

A line includes the points (4,1) and (8, 2). What is its equation in slope-intercept form?
Alisiya [41]

Answer:

y = \frac{1}{4} x  

Step-by-step explanation:

1) First, find the slope of the equation. Use the slope formula m= \frac{y_2-y_1}{x_2-x_1}. Substitute the x and y values of the given points into the formula and solve:

m = \frac{(2)-(1)}{(8)-(4)} \\m = \frac{2-1}{8-4}\\m = \frac{1}{4}

Thus, the slope is \frac{1}{4}.

2) Now, use the point-slope formula y-y_1 = m (x-x_1) to write the equation in point-slope form (from there we can convert it to slope-intercept). Substitute values for m, x_1, and y_1.

Since m represents the slope, substitute \frac{1}{4} for it. Since x_1 and y_1 represent the x and y values of one point the line intersects, choose any of the given points (it doesn't matter which one, the end result will be the same) and substitute its x and y values into the formula as well. (I chose (4,1), as seen below.) Then, isolate y to put the equation in slope-intercept form and find the answer.

y-(1) = \frac{1}{4} (x-4)\\y-1 = \frac{1}{4} x-1\\y = \frac{1}{4} x+0\\y=\frac{1}{4}x
