To solve this, you need to plug in the numbers for <em>h</em>.

-4(-12) ≥ 8 48 ≥ 8 yes

-4(-7) ≥ 8 28 ≥ 8 yes

-4(-5) ≥ 8 20 ≥ 8 yes

-4(-3) ≥ 8 12 ≥ 8 yes

-4(-2) ≥ 8 8 ≥ 8 yes

-4(-1) ≥ 8 4 ≥ 8 no

-4(1) ≥ 8 -4 ≥ 8 no

-4(3) ≥ 8 -12 ≥ 8 no

-4(8) ≥ 8 -32 ≥ 8 no

Hope this helped!

If disposable income is $20 trillion, taxes are $6 trillion, and transfers are $4 trillion, then income is $_____ trillion. Plea

Serjik [45]

Answer:

c) $22 trillion.

Step-by-step explanation:

We have been given that disposable income is $20 trillion, taxes are $6 trillion, and transfers are $4 trillion. We are asked to find income in trillions.

$\text{Disposable income}=\text{Income}+\text{Transfers}-\text{Taxes}$

$\$20=\text{Income}+\$4-\$6$ , where each amount is in trillions.

$\$20=\text{Income}-\$2$

$\$20+\$2=\text{Income}-\$2+\$2$

$\$22=\text{Income}$

Therefore, the income is $22 trillion.

SOMEONE HELP ASAPPPPPPP!!! PLEASE

(1) See below for a diagram. Basically, the distance on the ground from the person to the building (34 ft) is adjacent to the angle of elevation (74 degrees) and the height of the building (labeled h in the diagram) is the side opposite the angle. Since we are dealing with opposite and adjacent we use the tangent of the angle and tan = opp/adj

Specifically, $tan74= \frac{h}{34}$
$h=(34)(tan74)$ <span class="_wysihtml5-temp-placeholder"></span>
$h=118.6$ feet.

Please be sure your calculator is set to degrees (not radians) when you do this problem.

(2) Here since P & Q are complimentary it means that their sum is 90 degrees. Since this is a right triangle that means that the remaining angle (R) must be the right angle. See below for a diagram.

sin = opp/hyp. As the sin Q = 9/41 this means that 9 is the length of the side opposite Q (the side PR) and 41 is the length of the hypotenuse. This makes the remaining side (QR) 40 in length.

cos = adj/hyp. If we focus on angle P the side adjacent (next to) is 9 and the hypotenuse is 41. Thus the cos of P = 9/41.

You could have also realized that if P & Q are complimentary the sin P = cos Q and the cos P = sin Q. We were not asked about tangent but it is also the case that tan P = cot Q and cot P = tan Q.
