~PLEASE HELP ASAP OFFERING 25 POINTS PLEASE ANSWER ALL QUESTIONS~

lidiya [134]

Q1: Rearranging the last of the offered equations, you find

... selling price = overhead/(overhead percent) = $65.34/0.45 = $145.20

Then the net profit is

... net profit = selling price - cost - overhead = $145.20 - 49.32 - 65.34 = $30.54

Q2: Using the same net profit equation, you have

... net profit = selling price - cost - 0.47×selling price = 0.53×selling price - cost

... net profit = 0.53×$3,816,981.10 - 1,723,000.00 = $300,000

Q3: The applicable equation is

... net profit = markup - overhead

This matches selection ...

... B) Net Profit = $30.00 - 0.4 X Selling Price

If an arrow is shot upward on Mars with a speed of 56 m/s, its height in meters t seconds later is given by y = 56t − 1.86t2.

Zina [86]

Answer: (a) (i)50.42 m/s (ii) 51.35 m/s (iii) 52.094 m/s (iv) 52.2614 m/s (v) 52.27814 m/s

(b) 54.14 m/s

Step-by-step explanation:

The average speed over the given time interval [a,b]: = $\frac{y(b)-y(a)}{b-a}$

Given: If an arrow is shot upward on Mars with a speed of 56 m/s, its height in meters t seconds later is given by $y = 56t − 1.86t^2.$

(a)

(i) average speed = $\frac{y(2)-y(1)}{2-1}$

$=\frac{56(2)-1.86(2)^2-(56(1)-1.86(1)^2)}{1}$

$=50.42$ m/s

(ii) average speed = $\frac{y(1.5)-y(1)}{1.5-1}$

$=\frac{56(1.5)-1.86(1.5)^2-(56(1)-1.86(1)^2)}{0.5}$

$=51.35$ m/s

(iii) average speed = $\frac{y(1.1)-y(1)}{1.1-1}$

$=\frac{56(1.1)-1.86(1.1)^2-(56(1)-1.86(1)^2)}{0.1}$

$=52.094$ m/s

(iv) average speed = $\frac{y(1.01)-y(1)}{1.01-01}$

$=\frac{56(1.01)-1.86(1.01)^2-(56(1)-1.86(1)^2)}{0.01}$

$=52.2614
$ m/s

(v) average speed = $\frac{y(1.001)-y(1)}{1.001-01}$

$=\frac{56(1.001)-1.86(1.001)^2-(56(1)-1.86(1)^2)}{0.001}$

$=52.27814
$ m/s

(b) $y(1)=56(1)-1.86(1)^2$

$=56-1.86$

$= 54.14$ m/s

How do I solve for what is sin A for the triangle shown

PtichkaEL [24]

Option a:

sin A for the triangle is $\frac{3}{5}$ .

Solution:

The given triangle is a right triangle.

The adjacent side to angle A is AC.

The opposite side to angle A is BC.

Hypotenuse is AB.

AC = 8, BC = 6 and AB = 10.

Using trigonometric ratio formulas,

$$\sin \theta=\frac{\text { Opposite side }}{\text { Hypotenuse }}$

$$\sin A=\frac{BC}{AB}$

$$\sin A=\frac{6}{10}$

Divide both numerator and denominator by 2, we get

$$\sin A=\frac{6\div2}{10\div 2}$

$$\sin A=\frac{3}{5}$

Hence sin A for the triangle is $\frac{3}{5}$ .

Option a is the correct answer.
