Answer:
y -10 = 1/8(x +8)
Step-by-step explanation:
The point-slope form of the equation of a line with slope m through point (h, k) is ...
y -k = m(x -h)
You have m = 1/8, and (h, k) = (-8, 10).
Putting those numbers in the form gives ...
y -10 = 1/8(x -(-8))
You can simplify the double minus sign so you have ...
y -10 = 1/8(x +8)

A lot of math is about matching patterns and making substitutions. This is a good example of that.
I have no clue. i’m only here bc i need to ask a question but ic gl
You need 12 square roots of 1764 ?
Why not find the square root of 1764 first (it's 42) and then take 12 of those ?
5 x 10⁻³ is a scientific notation.
5 is the coefficient
10 is the base
3 is the exponent. The sign of the exponent signifies which direction the decimal point moved.
negative sign means that the decimal point moved from left to right in writing the scientific notation.
positive sign means that the decimal point moved from right to left in writing the scientific notation.
5 x 10⁻³ is 0.005 in standard form.
had the exponent been positive.
5 x 10³ is 5000 in standard form
Ok so the formula for the volume of a sphere is
r is the radius, which is half the diameter. Since the diameter of the whole sphere is 18 the radius would be half of that, which is 9. If you plug 9 into the formula you get 3052.08in.cubed. Now you must find the volume of the smaller core, the diameter of the core is 3, so the radius is 1.5 and if you plug that into the formula you get 14.13in.cubed. Since you're finding only the volume of the outside layer, you would subtract the volume of the core from the whole sphere, so 3052.08-14.13=3037.95
Your answer is 3037.95in.cubed
