If m∠C = 90°, side c = 29, and side a = 21, then side b = ___. 20 19 22 17

den301095 [7]

Answer:

b) 20

Step-by-step explanation:

Here m∠C = 90, It is a right triangle.

So we can use the Pythagorean theorem.

b = √(c^2 - a^2)

Given: a =21 and c = 29. Now let's plug in these values in the above formula, we get

b = √(29)^2 - (21)^2

b = √(841 - 441)

b = √400

b = 20

Therefore, the side length b = 20.

Hope this will helpful.

Thank you.

Match each operation involving f(x) and g(x) to its answer.

galben [10]

F(x)=1-x² and g(x)=√(11-4x)

(g+f)(2)=>

1-(2)²+√(11-4(2))

=√3-3

(f/g)(-1)

(1-(-1)²)/(√(11-4(-1))

=0

(g-f)(-1)

√(11-4*-1)-(1-(-1)²

=√15

(g×f)(2)

1-(2)²×√(11-4(2))

Susan, a recent college graduate, makes a base salary of $70,000 per year. Susan has federal income tax withholding of $12,000,

Damm [24]

Answer:

Susan's take-home pay $48,645.

Step-by-step explanation:

Given:

Susan, a recent college graduate, makes a base salary of $70,000 per year. Susan has federal income tax withholding of $12,000, and state tax withholding of $4,000. Employers are required to withhold a 6.2% Social Security tax and a 1.45% Medicare tax.

Now, to find Susan's take-home pay.

Basic salary = $70,000.

Now, her tax withholdings:

Federal income tax = $12,000.

State tax = $4,000.

Social security tax = 6.2% of $70,000.

$=\frac{6.2}{100} \times 70,000\\\\=0.062\times 70,000\\\\=\$4340.$
