In △PQR, find the measure of ∡P. (A)30.4° (B)59.6° (C)35.9° (D)54.1°

Kobotan [32]

ANSWER

(D)54.1°

EXPLANATION

The measure of angle P can be calculated using the cosine ratio.

We know the adjacent side to angle P to be 33.8 and the hypotenuse of the right triangle is 57.6 units.

$\cos(P) = \frac{adjacent}{hypotenuse}$

$\cos(P) = \frac{33.8}{57.6}$

Take cosine inverse,

$P= \cos ^{ - 1} (\frac{33.8}{57.6} )$

$P=54.07 \degree$

To the nearest tenth, the measure of <P is 54.1°

Kenyon ran for 8 miles each week while training. Here is his record of the number of miles he ran.

diamong [38]

Step-by-step explanation:

Let x be the miles Kenyon ran on tuesday

Let y be the miles Kenyon ran on thursday

Given,

Mon + Tues + Wed + Thu = 8mi

$1.2 + x + 1.6 + y = 8 \\ 2.8 + x + y = 8 \\ x + y = 8 - 2.8 \\ x + y = 5.2$

also given,

$y = x + 0.4 \\ - x + y = 0.4$

Now we have x + y = 5.2 as equation 1 and -x + y = 0.4 as equation 2

Using equation 1,

$x + y = 5.2 \\ x = 5.2 - y$

Substitute this equation into equation 2.

$- (5.2 - y) + y = 0.4 \\ - 5.2 + y + y = 0.4 \\ - 5.2 + 2y = 0.4 \\ 2y = 0.4 + 5.2 \\ 2y = 5.6 \\ y = 5.6 \div 2 \\ = 2.8mi$

Substitute y = 2.8 into equation 1.

$x + 2.8 = 5.2 \\ x = 5.2 - 2.8 \\ = 2.4mi$

Therefore Kenyon ran 2.4 miles on tuesday, and ran 2.8 miles on thursday.

Let F(x) 3x^2+2

shusha [124]

Answer: g(x)=12x^2+8

Step-by-step explanation:

original function f(x)=3x^2+2

Now to stretch function vertically and rename to g(x) we just multiply the function by 4;

g(x)=4(3x^2+2)=12x^2+8

Any questions feel free to ask. Thanks

Local income tax defention

mamaluj [8]

Answer:

Local governments in several states impose a local income tax. Local taxes are in addition to federal and state income taxes. Local income taxes generally apply to people who live or work in the locality. As an employer, you need to pay attention to local taxes where your employees work.

If the local income tax is a withholding tax, then you are required to withhold it from employee wages. Or if the local income tax is an employer tax, you must pay it.

Local income taxes are typically used to fund local programs, such as education, parks, and community improvement.
