Answer:

see below

Step-by-step explanation:

the actual way of writing sin inverse is arcsine, not sin⁻¹

since the output of sin is from -1 to 1, the domain of arsince is from -1 to 1. This is different than 1/sin(x), whose domain is all real numbers. we now write sin⁻¹ to fit it on the tiny buttons on our calculators

Answer:

-1/2, 7

Step-by-step explanation:

Given the expression

(x -7)(-4x -2)=0

This means that;

x - 7 = 0 and -4x - 2 = 0

x = 0+7 snd -4x = 2

x = 7 and x = -2/4

x = 7 and -1/2

Hence the solution from least to greatest is -1/2, 7

You are saving for a spring break cruise for the end of march of the next year thag costs $600. You start at $50 in August. At t

Doss [256]

March is 8 months away from August and the target amount is $600.
August = $50
September = $50 + (0.2*50)=$60
October = $60 + (0.2*60)=$72
November=$72+(0.2*72)=$86.4
December=$86.4 + (0.2*$86.4)=$103.68
January=$103.68+(0.2*103.68)= $124.416
February=$124.416+(0.2*124.416)=$149.3
March=$149.3 +(0.2*149.4)=$179.2

Total amount = $824.6

Which inequality is true?

DiKsa [7]

Answer:

C. 5 $\pi$ > 15

Step-by-step explanation:

In the given series of inequalities, the inequality sign determines the final outcome.

A. 4 $\pi$ - 2 < 10

4 $\pi$ < 12

$\pi$ < 3

Since $\pi$ < 3, then the inequality is false

B. $\pi$ + 9 < 12

$\pi$ < 3

Since $\pi$ < 3, then the inequality is false

c. 5 $\pi$ > 15

$\pi$ > 3

Since $\pi$ > 3, then the inequality is true

D. 6 > 2 $\pi$

3 > $\pi$

Since $\pi$ < 3, then the inequality is false

Thus, the only inequality that is true is option C.
