Answer:

1. -x³

2. m²

3. -1.5t⁷

Step-by-step explanation:

x⁶^½ = +/- x³

Since x is negative, postive square root would be -x³

m⁴^½ = +/- m²

Positive square root is m²

t¹⁷^½ = +/- t⁷

Since t is negative, postive square root would be -t⁷

1.5 × -t⁷ = -1.5t⁷

How do you solve this

blsea [12.9K]

Answer:

x = 8

Step-by-step explanation:

The angles shown are vertical angles

Vertical angles are congruent hence 8x + 36 = 5x + 60

( Notice that we just created an equation that we can use to solve for x )

We now solve for x algebraically

8x + 36 = 5x + 60

Step 1: Subtract 5x from both sides

8x - 5x + 36 = 5x - 5x + 60

Outcome: 3x + 36 = 60

Step 2: Subtract 36 from both sides

3x + 36 - 36 = 60 - 36

Outcome: 3x = 24

Step 3: Divide both sides by 3

3x/3 = 24/3

Outcome: x = 8

What is the general equation of a sine function with an amplitude of 6, a period of pi/4, and a horizontal shift of pi/2?

agasfer [191]

The general equation of the sine function y=f(x) is defined as

$Y=AsinB(x-C)+D$

where A is the Amplitude

B represents the frequency of the function with period equals $2\pi/B$

C represents the Horizontal shift, For Phase shift= -C/B

D represents the Vertical shift.

The data given that the amplitude of the function A=6

$B=\frac{2\pi}{Current\, period}=\frac{2\pi}{\pi/4}=8$

Vertical shift $D= 0$

Horizontal Shift $C= \pi/2$

Now plug in $\neq A=6, B=8\, and \, C=\pi/2$ in the general equation of sine function, we get

$y=6\sin8(x-\pi/2)+0\\y=6\sin 8(x-\pi/2))$

Help I've been stuck on this problem

777dan777 [17]

Answer:

a, b, + d

Step-by-step explanation:

You can start by using the distributive property and factor the equation out.

$-\frac{2}{5} (15-20d+5c)$

becomes

$15(-\frac{2}{5} ) - 20d(-\frac{2}{5} ) +5c(-\frac{2}{5} )$

which simplifies to

$-6+8d-2c$

So that's one answer.

If you multiply that answer times 5 you get

$-30+40d-10c$

and if you factor "-2" out of the original answer you get

$-2(3-4d+c)$

and that is all of the answers given.
