Answer:
FV=$823.004
Total interest earned=$63.004
Step-by-step explanation:
FV=PV×(1+i/n)^nt
PV=$760
I=4%
t=2 years
n=4
FV=760+(1+0.04/4)^4*2
=760+(1+0.01)^8
=760+(1.01)^8
=760+(1.0829)
=823.004
FV=$823.004
Total interest amount earned
=FV-PV
=$823.004-760
=$63.004

Answer:
7. ∠CBD = 100°
8. ∠CBD = ∠BCE = 100°; ∠CED = ∠BDE = 80°
Step-by-step explanation:
7. We presume the angles at A are congruent, so that each is 180°/9 = 20°.
Then the congruent base angles of isosceles triangle ABC will be ...
∠B = ∠C = (180° -20°)/2 = 80°
The angle of interest, ∠CBD is the supplement of ∠ABC, so is ...
∠CBD = 180° -80°
∠CBD = 100°
__
8. In the isosceles trapezoid, base angles are congruent, and angles on the same end are supplementary:
∠CBD = ∠BCE = 100°
∠CED = ∠BDE = 80°
Peter accumulated $7,500 in credit card debt. If the interest rate is 3.5% per year and he does not make any payments for 10 years, how much will he owe on this debt in 10 years by compounding continuously
Answer:
$10579.49
Step-by-step explanation:
The formula for amount gotten after a period of time (in years) on a principal which is compounded continuously is given as:
[tex]A = P(1 + r)^t[/tex]
where P = principal (amount borrowed)
r = interest rate
t = number of years
Peter accumulated $7,500 in credit card debt with interest rate as 3.5% per year and he does not make any payments for 10 years.
Therefore, his debt is:
[tex]A = 7500(1 + \frac{3.5}{100})^{10}\\ \\A = 7500 (1 + 0.035)^{10}\\\\A = 7500(1.035)^{10}\\[/tex]
A = $10579.49
He will owe $10579.49 after 10 years
Answer:
A= $10,643.01
Step-by-step explanation:
if you are rounded to the nearest cent
Identify the values of each variable in the formula. Remember to express the percent as a decimal.
A=?
P= $7,500
r= 0.035
t= 10 years
For compounding continuously, use the formula A=Pert.
Substitute the values in the formula and compute the amount to find

A circle is centered at D(-1,3). The point G(-10,1) is on the circle.
Where does the point J(-3, 12) lie?
Answer:on the circle
Step-by-step explanation:
Point J(-3, 12) is lying on the circle whose center is located at point D(-1, 3).
What is a circle?It is defined as the combination of points that and every point has an equal distance from a fixed point ( called the center of a circle).
We have a center of the circle at D(-1, 3)
And point G(-10, 1) is on the circle.
We know the standard equation of the circle when a center is given:
[tex]\rm (x-h)^2+(y-k)^2=r^2[/tex]
Where r is the radius of the circle and (h, k) is the center of the circle.
Here (h, k) ⇒ (-1, 3)
The circle equation becomes:
[tex]\rm (x+1)^2+(y-3)^2=r^2[/tex]
Put the point on the circle equation to get the radius of the circle:
[tex]\rm (-10+1)^2+(1-3)^2=r^2[/tex]
[tex]\rm (-9)^2+(-2)^2= r^2\\\\\rm 81+4 = r^2\\\\ \rm r = \sqrt{85} \ units[/tex]
Equation of circle is:
[tex]\rm (x+1)^2+(y-3)^2=85[/tex]
Now put the point J(-3, 12 ) in the circle equation:
[tex]\rm (-3+1)^2+(12-3)^2=85[/tex]
4+ 81 ⇒ 85
It means point J is lying on the circle.
Thus, point J(-3, 12) is lying on the circle whose center is located at point D(-1, 3).

Find the volume of a pyramid with a square base, where the perimeter of the base is
15.8 ft and the height of the pyramid is 20.4 ft. Round your answer to the nearest
tenth of a cubic foot.
(It’s on deltamath)
The volume of the given pyramid is 106.1 cubic foot.
To Find the Volume of a pyramid with a square base
Given:
The perimeter of the base is 15.8 feet
The base of the pyramid is square given of side say L .
Thus, from the formula of perimeter of square,
⇒ 4*L = 15.8 feet
∴ L = 3.95 feet
Now the base area of the pyramid is [tex]L^{2}[/tex] as it is a square .
∴ Base area = 3.95*3.95 square feet
= 15.6025 square foot
Now, formula for volume of the pyramid
= 1/3 * base area * height
⇒ Volume = 1/3 * 15.6025 * 20.4 cubic foot
∴ Volume = 106.097 cubic foot
Thus volume of the given pyramid is 106.1 cubic foot rounded off to nearest tenth.

the tires of a tractor are 5.25 feet tall. what measure would help to find how many feet the tractor will travel in 1 rotation
and how many feet would it travel
Answer:
16.485 feet
Step-by-step explanation:
Given that tire is 5.25 feet tall
any circular shape is as tall as its diameter.
we can say that diameter of tire is 5.25 feet.
in one rotation tire will start from one point of tire and reach it again.
it is like on a circle moving from on one point and then reaching to same point.
and we know that distance covered on moving on the point of circle is equal to circumference.
Thus, measure of circumference would help to find how many feet the tractor will travel in 1 rotation.
circumference of circle is given by [tex]\pi D[/tex]
where D is the diameter of circle.
we will us 3.14 as value of [tex]\pi[/tex]
thus, circumference of circle is[tex]\pi * 5.25 = 3.14*5.25 = 16.485[/tex]
Hence, tractor would travel 16.485 feet in one rotation.

Which graph represents functions f and g?
f: initial value of 200 decreasing at a rate of 4%
g: initial value of 40 increasing at a rate of 8%
Answer:
Choice C
Step-by-step explanation:
f: initial value of 200 decreasing at a rate of 4%

At my apartment I have a closet with 250 ft3 worth of space. If each of my spherical cannonballs have a radius of .75 feet, how many can I fit in my closet?
Answer:
141
Step-by-step explanation:
We need to first find the volume of the cannonballs and then, divide the volume of the closet by the volume of the cannonballs.
The radius of the spherical cannonball is 0.75 feet.
The volume of a sphere is:
[tex]V = \frac{4}{3} \pi r^3[/tex]
where r = radius
Therefore, the volume of the cannonballs is:
[tex]V = \frac{4}{3} * \pi * 0.75^3\\\\V = 1.77 ft^3[/tex]
Therefore, the number of cannonballs that can fit the closet is:
250 / 1.77 = 141.24
Since the number is a maximum and it must be a whole number, the number of cannonballs that can fit the closet is 141.

Answer:
C. 0.9
Step-by-step explanation:
If we take a good look at the scatter plot in the attachment showing numbers if oranges picked in relation to number of lemons harvested, we can infer that there's a strong positive correlation between both variables.
Thus, both variables are moving in the same direction. As one variable increases, the other variable increases. Also, the data points represented on the plot seem clustered close to the line rather than farther away.
This will suggest a positive correlation coefficient that is closer to 1.
From the options given above, the best estimate of the correlation coefficient would be 0.9.

mSPQ = (4x + 90)°, what is the value of x?
22
8.5
14
10
Answer:
x = 8.5
Step-by-step explanation:
In this question, we are to calculate the value of x.
To calculate this, we shall be utilizing one of the important properties of parallelogram.
This property is that opposite angles of a parallelogram are equal.
This means that mQSR = mSPQ = 4x + 90
Now to finally calculate x, we make use of another important parallelogram property which is that angles of parallelogram which faces each other are supplementary.
This means that they add up to be 180
Since mQSR faces mQRS
This means that;
4x + 90 + 9x -20 = 180
13x + 70 = 180
13x = 110
x = 110/13 which is approximately 8.5
make x the subject of the formula a=b(1-x)
Answer:
x = -(a - b)/b
Step-by-step explanation:
Solve for x:
a = b (1 - x)
a = b (1 - x) is equivalent to b (1 - x) = a:
b (1 - x) = a
Divide both sides by b:
1 - x = a/b
Subtract 1 from both sides:
-x = (a - b)/b
Multiply both sides by -1:
Answer: x = -(a - b)/b

Step-by-step explanation:
The given expression is 5s² + 23s + 24
We have to convert the given expression into the factored form.
One factor of the expression has been given as (x + 3)
5s² + 23s + 24 = 5s²+ 15s + 8s + 24
= 5s(s + 3) + 8(s + 3)
= (5s + 8)(s + 3)
So the factors of the expression will be (s + 3) and (5s + 8)
Therefore, the missing factor of the given expression is (5s + 8).

x° = ∠OBR = ∠ABC (base angles of a cyclic isosceles trapezoid)
Step-by-step explanation:
APRB form a cyclic trapezoid
∠APO = x° (Base angle of an isosceles triangle)
∠OPR = ∠ORP (Base angle of an isosceles triangle)
∠ORB = ∠OBR (Base angle of an isosceles triangle)
∠APO + ∠OPR + ∠OBR = 180° (Sum of opposite angles in a cyclic quadrilateral)
Similarly;
∠ORB + ∠ORP + x° = 180°
Since ∠APO = x° ∠ORB = ∠OBR and ∠OPR = ∠ORP we put
We also have;
∠OPR = ∠AOP = ∠BOR (Alternate interior angles of parallel lines)
Hence 2·x° + ∠AOP = 180° (Sum of angles in a triangle) = 2·∠OBR + ∠BOR
Therefore, 2·x° = 2·∠OBR, x° = ∠OBR = ∠ABC.
