Answer:
Interest earned in two years is approximately $1,837
Step-by-step explanation:
A= P( 1+r/n)^nt
Where,
A= principal + interest
P= principal= $10,000
r= interest rate = 8.5%
t= Time = 2years
n = periods = 4
A= P( 1+r/n)^nt
= 10,000(1+0.085/4)^4*2
= 10,000( 1 + 0.0213)^8
= 10,000(1.0213)^8
= 10,000(1.1837)
=11,837
A= $11,837
The interest earned in two years is
A = p + I
A - P = I
$11,837 - $10,000 = I
$1,837 = I
I= $1,837
Interest earned in two years is approximately $1,837
Determine the standard form of the equation of the line that passes through (-2,0) and (-8,5)
Answer: 5/6x + 1y = -5/3 or 5x + 6y = -10
Step-by-step explanation:
First you need to write an equation in slope intercept form and convert it to Standard form. To write an equation in slope intercept form using the coordinates we need to find the slope and the y-intercept.
The slope is the change in y over the change in x.
0-5 = -5
-2-(-8) = 6
Slope is -5/6
Now find the y intercept using the formula y =mx + b where m is the slope and b is the y-intercept.
5 = -5/6(-8) + b
5 = 40/6 +b
-40/6 -40/6
b= -5/3
So now the equation is y= -5/6x - 5/3
So now write it in standard form as ax+by = c where x is constant.
y = -5/6x -5/3
+5/6x
5/6x + 1y = -5/3 now you can multiply it by 6 to get rid of the fractions.
5/6x(6) + y(6) = -5/3(6)
5x + 6y = -10

if x+y=5,x-y=4,find the value of x²-y²
Answer:
20
Step-by-step explanation:
→ First find the value of x and y
x + y = 5
x - y = 4
→ Add the equations to cancel out the y's
2x = 9
→ Divide both sides by 2 to find the value of x
x = 4.5
→ Substitute x = 4.5 back into x - y = 4 to find the value of y
4.5 - y = 4
→ Minus 4.5 from both sides to isolate -y
-y = -0.5
→ Multiply everything by -1
y = 0.5
→ Substitute x = 4.5 and y = 0.5 into x² - y²
4.5² - 0.5² = 20.25 - 0.25 = 20
A product has a production cost function C(x)x and a revenue function R(x)x. Find and analyze the break-even quantity, then find the profit function.
A product has a production cost function C(x) =165x + 3630 and a revenue function R(x)= 220x. Find and analyze the break-even quantity, then find the profit function.
Answer:
the break-even quantity = 66
the profit function = 55x - 3630
Step-by-step explanation:
Given that:
C(x) = 165x + 3630
R(x) = 220 x
The Break-even quantity is C(x) = R(x)
∴
165x + 3630 = 220x
collecting the like terms, we have:
3630 = 220 x - 165 x
3630 = 55 x
[tex]x = \dfrac{3630}{55}[/tex]
x = 66
Thus, the break-even quantity = 66
The profit function = R(x) - C(x)
The profit function = 220x - 3630 - 165x
By rearrangement
The profit function = 220x - 165x - 3630
The profit function = 55x - 3630

if alpha and beta are zeroes of the quadratic polynomial f(x) = x2-x-2 then find a polynomial whose zeroes are 2alpha + 1 and 2beta + 1
Answer:
Step-by-step explanation:
Hello, as alpha and beta are zeroes of
[tex]x^2-x-2[/tex]
it means that their sum is alpha+beta=1 and their product alpha*beta=-2.
The polynomial whose zeroes are 2 alpha + 1 and 2 beta + 1, means that the sum of its zeroes is 2(alpha+beta)+2=2+2=4
and the product is (2alpha+1)(2beta+1)=4 alpha*beta + 2(alpha+beta) + 1 = 4 * (-2) + 2*(1) +1 = -8 + 2 + 1 = -5. so one of these polynomials is

The figure to the right has its congruent segments marked. Find
the measure of AB.
17 meters
B
5 meters
AB = meters
(Type an integer or a decimal.)
Answer:
AB = 17 meters
Step-by-step explanation:
Given that the triangle, ∆ABC, has 2 congruent sides that are indicated with a single marking on segment AC and segment AB, both segments would be of equal measure.
Therefore, since the measure of segment C is 17 meters, the measure of segment AB = measure of segment AC = 17 meters.
Segment AB = 17 meters. It is congruent to segment AC.

how many phone numbers are possible in the (404) area code if the seven digit number have the form FGH-XXXX where F is restricted to 3-9 and X,G and H can be any digit 0-9?
Answer:
900 phone numbers possible.
Step-by-step explanation:
Given the seven digit numbers are of the form:
FGH-XXXX
Possibilities for F = 3 - 9 and X i.e. 9 possibilities
Possibilities for G = 0 - 9 i.e. 10 digits
Possibilities for H = 0 - 9 i.e. 10 digits
To find:
How many numbers are possible ?
Solution:
This problem is nothing but a problem in which we have to find out how many numbers are possible where each digit has a few options available.
Number of ways to select F = 8 digits from 3 to 9 and 1 alphabet X = 9
Number of ways to select G = 10 digits from 0 to 9
Number of ways to select H = 10 digits from 0 to 9
XXXX part will be same in all the numbers.
So, total phone numbers possible = [tex]9 \times 10 \times 10 = \bold{900}[/tex]
Hence, the answer is:
900 phone numbers possible.

Alice is riding a Ferris wheel, where t is time in seconds. Suppose the Ferris wheel is 22 m tall. Let h(t) = 11cos(12t) represent the height of Alice in m above or below the centre of the Ferris wheel. Relative to the centre of the Ferris wheel, what is the lowest height Alice achieves?
Answer:
Alice reaches 11 metres below the centre as lowest height.
Step-by-step explanation:
Cosine is a bounded function between -1 and 1, so that the lowest height that Alice achieves in Ferris wheel is:
[tex]h(t) = 11\cdot \cos (12\cdot t)[/tex]
Where:
[tex]t[/tex] - Time, measured in seconds.
[tex]h(t)[/tex] - Height with respect to centre, measured in metres.
If [tex]\cos (12\cdot t) = -1[/tex], then:
[tex]h_{min} = 11\cdot (-1)[/tex]
[tex]h_{min} = -11\,m[/tex]
Alice reaches 11 metres below the centre as lowest height.
Answer: 80m got it on edge
In the given diagram, if AP = 15 cm, AQ = 24 cm and PB + QC = 26 cm, find QC – PB, given PQ || BC.
Answer:
QC - PB = 6
Step-by-step explanation:
Given PQ is parallel to BC then it divides the sides proportionally, that is
[tex]\frac{AP}{AQ}[/tex] = [tex]\frac{PB}{QC}[/tex] = [tex]\frac{15}{24}[/tex] = [tex]\frac{5}{8}[/tex] , then
[tex]\frac{PB}{QC}[/tex] = [tex]\frac{5}{8}[/tex] ( cross- multiply )
8PB = 5QC → *
Given PB + QC = 26 , then
PB = 26 - QC
Substitute into *
8(26 - QC) = 5QC ← distribute left side
208 - 8QC = 5QC ( subtract 5QC from both sides )
208 - 13QC = 0 ( subtract 208 from both sides )
- 13QC = - 208 ( divide both sides by - 13 )
QC = 16
Thus PB = 26 - QC = 26 - 16 = 10
QC - PB = 16 - 10 = 6
