If a right triangle has side lengths of 3 cm and 7 cm, what is the length of the hypotenuse? brainliest will report if answer is

Neko [114]

Answer:

Solution given:

length[a]=3cm

base(b)=7cm

hypotenuse [c]=?

we have

by using Pythagoras law

a²+b²=c²

3²+7²=c²

c=√58=7.61m

the length of the hypotenuse is 7.61 or 7.6 or8m.

Determine if (3,-4) is a solution to y < 2x – 5.

spin [16.1K]

You would plug in the ordered pair into the equation.

1. Put the y value from the ordered pair in the y spot, and the x value in the x spot.

2. add up the x side

Does it equal the y side?

Im a bit confused as the question says “&lt” at least on my end? I’m not sure if that’s just the way it ended up being written or if it means something. Sorry if my answer doesn’t apply :(. But if it does, I hope it helps!

State the amplitude, period, phase shift, and vertical shift of the function m(t)= 7 cos (t+3)

tiny-mole [99]

Answer:

Step-by-step explanation:

Given a sinusoidal function in the form $f(x)=Acos(Bx+C)+D$ , we can say:

A is the amplitude
$\frac{2\pi}{B}$ is the period
$-\frac{C}{B}$ is the phase shift
D is the vertical shift

From the function given m(t) = 7 Cos (t+3), we see that

A = 7

B = 1

C = 3

D = 0

Thus, from the info, we can say

Amplitude = 7

Period = 2π

Phase Shift = -3

Vertical Shift = 0

Answer choice B is right.
