vertex (3,-2) and y-intercept (0,7).
Write your answer in this form: (X₁,Y1), (X2,2).
If necessary, round to the nearest hundredth.
Enter the correct answer.
Answer:
3±√2/3 = x
Step-by-step explanation:
As you already have the vertex, the equation for this is y = a(x – h)^2 + k,
so by plugging all this in using the vertex coordinates, you get y = 3(x - 3)^2-2, so, if you divide everything by three you get 2/3 = (x - 3)^2

By applying definitions of trigonometric reasons, Pythagorean theorem and a trigonometric expression, the value of the sin 2θ is equal to - (5/18) · √11.
How to determine the value of trigonometric reasons
In this question we must take into accounts the definitions of the trigonometric reasons sine and secant and the Pythagorean theorem as well.
If sec θ < 0 and csc θ > 0, then sin θ > 0 and cos θ < 0, the angle is in the second quadrant (0.5π < θ < π, x < 0, y > 0) and we have the following expression:
sec θ = r/x
[tex]\frac{r}{x}= -\frac{6\sqrt{11}}{11}[/tex]
Then x = - 11, r = 6√11 and the value of y is:
[tex]y = \sqrt{r^{2}-x^{2}}[/tex]
y = 5√11
By trigonometric expressions we have this formula for sin 2θ:
sin 2θ = 2 · sin θ · cos θ
sin 2θ = 2 · (y/r) · (x/r) = (2 · x · y)/r²
sin 2θ = [2 · (- 11) · (5√11)]/396
sin 2θ = - (5/18) · √11
By applying definitions of trigonometric reasons, Pythagorean theorem and a trigonometric expression, the value of the sin 2θ is equal to - (5/18) · √11.

Are these numbers rational or irrational? -7 √10 (square root of 10) √16 (square root of 16) 52% 1.235 1. Rational 2. Irrational
Step-by-step explanation:
remember what a rational number is ?
any number that can be expressed by a/b, with a and b being integer numbers, and b different to 0.
so,
-7 = -7/1 rational
sqrt(10) irrational, because there is no rational number that multiplied by itself is 10.
sqrt(16) = sqrt(4×4) = 4 = 4/1 rational
52% = 52/100 rational

Please select the best answer from the choices provided
A
B

D
Answer:
a. y = -1/2x - 2
Step-by-step explanation:
The correct answer choice can be determined by finding the slope of the line. The slope is the ratio of rise to run.
__
slopeThe x-intercept is 4 units left of the y-axis. As the line "runs" those 4 units, it "rises" -2 units to intercept the y-axis at -2. The slope of the line is ...
m = rise/run = -2/4 = -1/2
In the slope-intercept form of the equation of a line, the slope is the coefficient of x. This information is sufficient to let us choose the first answer choice.
__
equationThe slope-intercept equation is ...
y = mx +b . . . . . . . slope m, y-intercept b
We know the slope is -1/2, and the y-intercept is where x=0, at y=-2. Then the equation is ...
y = -1/2x -2 . . . . . matches choice A
_____
Additional comment
When answering multiple-choice questions, you only need to do enough work to tell which answers are not viable.
When we plot the points, we see that the line has negative slope. (eliminates choice C). The slope is shallow, rather than steep (the x-intercept is farther from the origin than the y-intercept), so the magnitude of the slope is less than 1 and choices B and D are eliminated.

What is the return on equity for a firm with 15% return on assets, 10% return on debt, and a .75 debt/equity ratio?
The return on equity for the firm is 18.75%.
Return on equityReturn on equity=Return on assets +[ (Debt/Equity ratio)×(Return on assets-Return on debt)]
Let plug in the formula
Return on equity=.15+ [(.75)× (.15-.10)]
Return on assets=.15+ (.75×0.05)
Return on assets=.15+0.0375
Return on equity=0.1875×100

Chua Chang & Wu Inc. is planning its operations for next year, and the CEO wants you to forecast the firm's additional funds needed (AFN). Data for use in your forecast are shown below. Based on the AFN equation, what is the AFN for the coming year?
Based on the AFN equation, the AFN for the coming year will be -$16000.
How to calculate the AFN?Last year's sales =$200,000
Sales growth rate = g = 40%
Forecasted sales = S0 × (1 + ) = 280,000
∆S = change in sales = S1 − S0 = $80,000
Last year's total assets = A*0 = A*0 since full capacity $135,000
Forecasted total assets = A*1 = A*0 × (1 + g) = $189,000
Last year's accounts payable = $50,000
Last year's accruals= $20,000
L*0 = payables + accruals = $70,000
Profit margin = M = 20.0%
Target payout ratio = 25.0%
Retention ratio = (1 − Payout) = 75.0%
AFN = (A*0/S0)ΔS – (L*0/S0)ΔS – Margin × S1 × (1 − Payout)
AFN = $54,000 – $28,000 – $42,000
= -$16,000
The complete question goes thus:
Chua Chang & Wu Inc. is planning its operations for next year, and the CEO wants you to forecast the firm's additional funds needed (AFN). Data for use in your forecast are shown below.

Last year's accounts payable = $50,000

Which number is equivalent to 16 1/2
Answer:
8
Step-by-step explanation:
Find the absolute mean deviation of this data set:
8, 8, 4, 12
Answer:
2 is the absolute mean deviation
Step-by-step explanation:
absolute mean deviation is
the average of the differences of the data from the average
8, 8, 4, 12
1. take the average
8+8+4+12=32 -> 32/4 = 8
2. subtract each number from this average
8 - 8 = 0
8 - 8 = 0
4 - 8 = 4 (there are no negative answers)
12 - 8 = 4
3. take the average of these subtractions
0+0+4+4=8 -> 8/4 = 2
4. answer: 2 is the absolute mean deviation
