Answer:
for the second questio it is certainly The last choice D
Step-by-step explanation:
Y = 10 units
Explanation:
The two triangles are similar due to Angle-Angle similarity theorem. So, the ratios of their sides are equal
y/14 = 15/(15 + 6)
y/14 = 15/21
y = 10 units
Answer:
12 ÷ 5
Step-by-step explanation:
Answer:
2x - 7y = -34.
Step-by-step explanation:
As the line we want is perpendicular to y= -7/2 x + 9 it's slope will be
-1 /(-7/2) = 2/7.
Now we find the point of intersection ofn the 2 given lines:
x + y = 10
3x - 4y = -12
Multiply the first equation by -3:
-3x - 3y = -30
Now add this last equation to the second one:
-7y = -42
y = 6
Plug y = 6 into the first equation:
x + 6 = 10
x = 4.
So the point of intersection is (4, 6) and the equation we want passes through this, so using the point-slope form of straight line we have:
y - 6 = 2/7(x - 4)
7y - 42 = 2(x - 4)
7y - 42 = 2x - 8
2x - 7y = -42 + 8
2x - 7y = -34
Answer:
$6,283.56
Step-by-step explanation:
The net present value is the present value of after tax cash flows from an investment to the amount invested in a project.
Net present value can be calculated using a financial calculator
Cash flow in year zero = -$290,000
Cash flow each year from year one to three = 0
Cash flow each year from year four to twelve = $64,000.
I = 9%
NPV = $6,283.56
To find the NPV using a financial calacutor:
1. Input the cash flow values by pressing the CF button. After inputting the value, press enter and the arrow facing a downward direction.
2. After inputting all the cash flows, press the NPV button, input the value for I, press enter and the arrow facing a downward direction.
3. Press compute
