ABC has side lenths 20, 24, and 31. Do the side lenghts form a Pythagorean triple?

No they don't.
Phythagorean triple is when the sum of the squares of two numbers is equal to the square of another number.

20^2 + 24^2 = 400 + 576 = 976
31^2 = 961

20^2 + 24^2 should have been equal to 31^2 but that's not the case. So, the side's length don't form a triple.

Hope it helped!

1) State the amplitude, period, phase shift, vertical shift and graph

bogdanovich [222]

Answer:

See answers and explanations below (along with a visual graph)

Step-by-step explanation:

For the function $y=acos(b(x+c))+d$ :

Amplitude: $|a|$

Period: $\frac{2\pi}{|b|}$

Phase shift: $\frac{-c}{b}$

Vertical shift: $d$

Therefore, for $y=2cos(\frac{2}{3}(\theta+\pi))-1$ :

Amplitude: $|a|=|2|=2$ , which is 2 units above and below the midline (see d)

Period: $\frac{2\pi}{|b|}=\frac{2\pi}{|\frac{2}{3}|}=\frac{2\pi}{\frac{2}{3}}=3\pi$ , so the cycle will repeat every 3π units

Phase shift: $\frac{-c}{b}=\frac{-\frac{2\pi}{3} }{\frac{2}{3} }=-\pi$ , or π units to the left

Vertical shift: $d=-1$ , or 1 unit down

Solve v times w squared+ y= x. Solve for w. Please show me how you got the answer!

faltersainse [42]

$▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪$

let's solve for " w "

$vw {}^{2} + y = x$

$vw {}^{2} = x - y$

${w}^{2} = \dfrac{x - y}{v}$

$w = \sqrt{ \dfrac{x - y}{v} }$

Write an equation in point-slope form of the line that passes through (3, -8) and (7,-2).

sashaice [31]

Answer:

A line that passes through (3, -8) and (7,-2).

Denote equation of that line: y = ax + b

=> Slope a can be directly determined by:

a = (7 - 3)/(-2 - -8) = 4/6 = 2/3

=> y = (2/3)x + b

This line passes (3, -8), then: -8 = (2/3)*3 + b => -8 = 2 + b => b = -10

=> y =(2/3)x - 10

There are other ways to find equation of line.

Hope this helps!
