I PROMISE I GIVE POINTS PLZ PLZ POINTS JUST ANSWER PLZ

1 answer:

2] y= 3x + 20

Divide both sides by 3 to simplify
y-20/3 =x

Switch sides
x= y-20/3.

For the first question, it is very confusing and you have to learn how to use the Quadratic formula.

What are the amplitude, period, and phase shift of the given function? f(t)= -1/2sin (4-2π)

artcher [175]

Answer: A

Step-by-step explanation:

ok, so amplitude is the A term, basically the first thing in the equation (1/2) but can’t be negative. the phase shift is in the parentheses, it’s that pi/2, (or 1/2 pi). the period is 1/2 pi since the formula is 2pi/4. (i think that’s right i’m not 100 percent sure

Which equation represents a line that passes through (2, -1/2) and has a slope of 3?

Anika [276]

Answer:

Step-by-step explanation:

The line passes through the point (2, -1/2) and has a slope of 3.

We can use the point-slope form, given by:

$y-y_1=m(x-x_1)$

Where (x₁, y₁) is a point, and m is the slope.

Let (2, -1/2) be (x₁, y₁). We will substitute 3 for m. Therefore:

$\displaystyle y-\Big(-\frac{1}{2}\Big)=3(x-(2))$

Simplify:

$\displaystyle y+\frac{1}{2}=3(x-2)$

Therefore, our answer is C.

Solve for the indicated variable

anygoal [31]

Answer:

243.911, or rounding to the nearest unit, 244.

Step-by-step explanation:

For this, you need to know a concept in Trigonometry called "Law of Sines". This states that the ratio of any side of a triangle to the sine of the angle opposite is equal for all cases in that triangle.

Knowing this:

$\frac{200}{ \sin(48) } = \frac{x}{ \sin(65) } \\ x \sin(48) = 200 \sin(65) \\ x = \frac{200 \sin(65) }{ \sin(48) } \\ x = 243.911$
