Which graph can be used to find the solution of the following system of equations?

Mathematics

STatiana [176]3 years ago

Answer:

A

Step-by-step explanation:

1. Honestly, my course of action, if allowed to, would be to use my graphing calculator. Obviously, you can graph the first equation but the second one requires some rearranging, keeping in mind that we are <u>isolating the y</u>.

2y-2x=10

2y=2x+10

y=x+5

So now we have an equation of the line. Simply enter both of these equations into your graphing calculator and you're all set.

I hope this helps!

Find the exact volume of a waffle ice cream cone with a 9​-in. diameter and a height of 15 inches.
boyakko [2]

The volume of a cone is:

V_{cone}=\dfrac{1}{3}\pi r^2h, where r is base's radius, h is cone's height.

If diameter is 9 in, then radius is 4.5 in and

V_{cone}=\dfrac{1}{3}\pi (4.5)^2\cdot 15=101.25\pi.

Answer: V_{cone}=101.25\pi.

Hi :), im really struggling with this. Just wanted to know if anyone can explain step by step for me please. Id really appreciat
Dvinal [7]

Answer:

314 m²

Step-by-step explanation:

the formula for the surface area of a sphere (As) is

As = 4×pi×r²

the radius r (half of the diameter) is clearly indicated as 5m.

so, As = 4×3.14×5² = 4×3.14×25

I don't even need a calculator for this, as 4×25 = 100

so, As = 100×3.14 = 314

(you know, when multiplying by 10, the decimal point moves right one position. multiply by 100 it moves 2 positions, and so on).
