Is a triangle with sides of length 6ft., 21ft,. 23ft,. a right traingle? show how you know.

No it is not a right triangle. Because using Pythagorean's Theorem 6 squared, 36, plus 21 squared, 441, is 477. And when you do 32 squared is equals to 529. And therefore 477 is not equal to 529.

Line L has equation y = 4x - 7, and line M is parallel to line L and passes through the point (2, 15). Determine the equation of

Artist 52 [7]

Answer:

A: y = 4x + 7

Step-by-step explanation:

Step 1: Our line is parallel to this line, so it has the same slope, but a different y-intercept, so set up the equation...

y = 4x + b

We are given a point (x, y) of (2, 15), so plug that in and solve for b.

15 = 4(2) + b

15 = 8 + b (simplify)

7 = b (subtract 8 from both sides to isolate b)

So the equation of our line is y = 4x + 7

Which of the following functions gives the length of the base edge, a(v), of a right square pyramid that is 8 inches tall as a f

Reil [10]

Answer:

$\large\boxed{a(V)=\sqrt{\dfrac{3V}{8}}}$

Step-by-step explanation:

The formula of a volume of a square pyramid:

$V=\dfrac{1}{3}a^2h$

a - base edge

h - height of a pyramid

We have H = 8in.

Substitute and solve for a:

$\dfrac{1}{3}a^2(8)=V\\\\\dfrac{8}{3}a^2=V\qquad\text{multiply both sides by}\ \dfrac{3}{8}\\\\\dfrac{3\!\!\!\!\diagup^1}{8\!\!\!\!\diagup_1}\cdot\dfrac{8\!\!\!\!\diagup^1}{3\!\!\!\!\diagup_1}a^2=\dfrac{3}{8}V\\\\a^2=\dfrac{3V}{8}\Rightarrow a=\sqrt{\dfrac{3V}{8}}$

faust18 [17]

Answer:

Step-by-step explanation:

Let the numbers of steps you can take to reach your goal be x

Your goal is to take at least 10,800 steps per day and you have walked 7370 steps already.

x + 7370 >= 10800

x >= 10800 - 7370

x >= 3430
