Answer:

4pie

Step-by-step explanation:

period = time/number of oscillation

time=4pie

number of oscillation = 1

then

period = 4p/1= 4p

Given the equation y − 4 = three fourths(x + 8) in point-slope form, identify the equation of the same line in standard form.
IRINA_888 [86]

Answer:

3x-4y=-40

Step-by-step explanation:

The standard form of a linear equation is  ax+by=c.

The given line has equation:

y-4=\frac{3}{4}(x+8)

This is the point-slope form of the given line.

To find the standard form, we clear the fraction

4y-16=3(x+8)

We expand the parenthesis now to get:

4y-16=3x+24

We group the variables on the LHS and the constants on the RHS.

4y-3x=24+16

-3x+4y=40

Multiply through by -1

3x-4y=-40

This is of the form: ax+by=c.

13. What is the value of x?
Scilla [17]

9514 1404 393

Answer:

  B.  50

Step-by-step explanation:

The alternate interior angles at transversal t across parallel lines AB and CD will be congruent.

  2x +40 = x +90

  x = 50 . . . . . . . . . . . subtract x+40

The value of x is 50.

_____

<em>Check</em>

2x+40 = 2×50 +40 = 140

x+90 = 50 +90 = 140 . . . . so the obtuse angles are congruent, as they should be

___

<em>Additional comment</em>

The lines AB and CD are not shown as being parallel. We have to assume they are, or we cannot work the problem.

20 Points + Brainliest for the answer and Explanation!!!
Vlad1618 [11]

Answer:

P+Q=5x^2+4

Q-P=-x^2-4x+16

Step-by-step explanation:

We are given

P=3x^2+2x-6

Q=2x^2-2x+10

Calculation of P+Q:

P+Q=3x^2+2x-6+2x^2-2x+10

now, we can combine like terms

P+Q=3x^2+2x^2+2x-2x+10-6

P+Q=5x^2+0+4

P+Q=5x^2+4

Calculation of Q-P:

Q-P=2x^2-2x+10-(3x^2+2x-6)

Firstly, we will distribute negative sign

Q-P=2x^2-2x+10-3x^2-2x+6

now, we can combine like terms

Q-P=2x^2-3x^2-2x-2x+6+10

Q-P=-x^2-4x+16

PLEASE HELP ME<br> Use the function below to find f(2).<br><br> f(x) = 1/3 x 4^x
Anna71 [15]

f(2) This means that x is 2, so you plug in 2 for x in the equation

f(x)=\frac{1}{3} (4^x)

f(2)=\frac{1}{3}(4^2)

f(2)=\frac{1}{3} (16)

f(2)=\frac{16}{3}


Your answer is D
