Answer:
$13.14
Step-by-step explanation:
Suppose you want to accumulate $120,000 for your retirement in 30 years.
Consider these two plans:
Plan A: make a single deposit into an account with an annual compounding and an APR of 5%.
Plan B: Make a single deposit into an account with continuous compounding and an APR of 4.8% 
1.) how much do you need to deposit in each amount in order to reach the goal?
2.) calculate the current APR the compounding period, and the claimed APY for your personal savings account. (Or pick a rate from a nearby bank)
3.) calculate the APY on your account (or someone u know)
4.) Does your calculation agree with the APY claimed by the bank?
The amount that would be needed to be deposited in order to reach the goal is:
Plan A: $27,765.29.Plan B: $28,431.33Calculations and Parameters:Since Plan A compounds annually at an apr of 5%.
and plan B compounds continuously at an apr of 4.8%
PART AUsing the formula for annual compounding
[tex]f = p * (1+r)^n[/tex]
Where
f is the future value which is equal to 120,000p is the present value.r is the interest rate per time period.n is the number of time periods.Because the compounding is done annually, then the APR/100= 0.05
Also, because the time periods are annual, hence, the time periods would be equal to the number of years = 30.
Putting the values together:
120,000 = p * (1.05)^30.
divide both sides of this formula [tex](1.05)^3^0[/tex] to get:
[tex]120,000 / (1.05)^3^0[/tex] = p which makes p equal to $27,765.29.
PART BTo solve for the PART B answer
the formula for continuous compounding is:
[tex]f = p * e^(r*n)[/tex]
Where
r is the interest rate per time period which is in years.n is the number of time periods which is in years.The formula becomes:
[tex]120,000 = p * e^(.048 * 30).[/tex]
divide both sides of this equation by [tex]3^(.048 * 30)[/tex] to get:
[tex]120,000 / (e^(.048*30))[/tex] = p which makes p equal to $28,431.33.

Anybody know the slope of the line is … Help
Answer: The slope is -1
Step-by-step explanation:
When you are given a line on a graph all you need to do is pick two points on the line and calculate the change over both the x and y-axis.
Pick both points to be at a position on the line that is easy to read. IE the intersection between two grid lines. For this problem lets go with the first point at (0,1) and the second point at (1,0).
Now we want to calculate the change in rise (the y-component) and divide by the change in the run (the x-component). Point 1 has a y-component of 1 and point 2 has a y-component of 0.
1 - 0 = 1 = rise
Point 1 has an x-component of 0 and point 2 has an x-component of 1.
0 - 1 = -1 = run
rise/run = 1/-1
Slope = -1

3.2] I can rearrange formulas to solve for a specified variable.
Solve for r.
h=r-m
Answer:
r = h + m
Step-by-step explanation:
h = r - m
Switch sides.
r - m = h
Add m to both sides.
r - m + m = h + m
Simplify the left side. -m + m = 0
r = h + m

solve these quetions......
Step-by-step explanation:
a.) 9
When you divide with a fraction you do the reciprocal of the fraction (basically flipping numerator and denominator) then multiplying (since the opposite of division is multiplication.
So if you flip
[tex]\frac{1}{9} [/tex]
It would be:
[tex] \frac{9}{1} [/tex]
9/1 is the same as 9 so:
1 times 9 = 9
b.) 15
Same thing like we did above, just do the reciprocal the multiply.
[tex] \frac{1}{5} [/tex]
Becomes
[tex] \frac{5}{1} [/tex]
5/1 is the same as 5.
3 times 5 = 15

Using the standard format of a perfect-square quadratic sum, it is found that the value that completes the expression is 169.
What is the standard format of a perfect-square binomial sum?It is represented by:
(a + b)² = a² + 2ab + b².
In this problem, we have that the expression is:
a² + 2ab + b² = h² + 26 + b².
Hence a = 1, 2ab = 26 -> b = 13, thus the value that completes the expression is:
b² = 13² = 169.

Answer:
Q=9
Step-by-step explanation:
if we get the bottom lengths of both triangles and divide them by eachother we can find the scale factor. so 12/4=3 meaning the scale factor is 3 meaning the bigger triangle is 3 times bigger so if we have the smaller version of the length of Q we just have to multiply 3 by 3 to get the enlarged version so Q=9inch

Need Answer Please And thank you
Answer:
157.78
Step-by-step explanation:
Area of a trapezoid = ( sum of base lengths / 2 ) × height
the base lengths of the trapezoid shown are 8.7m and 16.3 + 7.2 = 23.5m
the height is 9.8m
so area = (( 8.7 + 23.5 ) / 2) × 9.8
==> add 8.7 and 23.5
area = (32.2 / 2) × 9.8
==> divide 32.2 by 2
area = 16.1 × 9.8
==> multiply 16.1 and 9.8
area = 157.78
find the volume of number ten pls i know the answer is 449.57 the figure is to the left
Answer:
see below ( I do not think 449.57 m^2 is correct for surface area)
Surface area = 374.65 m^2 Volume = 448.83 = ~~ 449 m^3
Step-by-step explanation:
Find the SURFACE AREA (NOT the volume)
Height of cone = sqrt ( 13^2 - 4.5^2) = 12.1963 m
surface area equation for cone = pi * r * (r+ sqrt (h^2+r^2) ) = 247.4 m^2
Sphere surface area = 4 pi r^2 = 254.5 m^2
HEMIsphere is 1/2 of this = 127.235 m^2
Add the two surface areas = 374.65 m^2
For VOLUME: cone 1/3 pi r^2 h = 257.979 m^3
HEMIsphere = 1/2 4/3 pi r^3 = 190.851 m^3
Total VOLUME is then 448.83 m^3

Pedro bought 13 and 5
so 13+5 = 18 (x)
so rearrange the equation to be x-5=13
so imagine x=18 and it would work:
18-5=13
Answer: B. x - 5 = 13
Step-by-step explanation:
Since Pedro bought the picture frames for his mother, we will see what she does with them. 5 go to her sister and 13 are kept for herself. Let x be the number of picture frames Pedro buys.
5 + 13 = x
This is not one of the answer choice, but x - 5 = 13 is. If we subtract 5 from both sides of the equation we created above, this proves to be our answer.
B. x - 5 = 13

Solve the system using elimination.
4X +5Y = 22
X +3Y =0
Answer:
x = 3
y = -2
--------------------------------------------------------------------------------------------------------
4x + 5y = 2........i
2x + 3y = 0........ii
---------------------------------------------------------------------------------------------------------
Let's start by eliminating x, so we multiply i by 2 and ii by 4
2|4x + 5y = 2
4|2x + 3y = 0
So that we have
8x + 10y = 4..........iii
8x + 12y = 0..........iv
---------------------------------------------------------------------------------------------------
Subtracting iv from III, we have
-2y = 4
y = 4/-2
y = -2
---------------------------------------------------------------------------------------------------
Going ahead and substituting this value of y in eqn i, we have
4x + 5(-2) = 2
4x - 10 = 2
4x = 2 + 10
4x = 12
x = 12/4
x = 3

From a hot-air balloon, Enola measures a 22 degrees angle of depression to a landmark that’s 310 feet away, measuring horizontally. What’s the balloon’s vertical distance above the ground? Round your answer to the nearest hundredth of a foot if necessary.
Answer:
125.25 ft
Step-by-step explanation:
The geometry of the problem can be modeled by a right trianlge in which the side adjacent to the angle is 310 ft, and the side opposite the angle is the one we want to find. The relevant trig relation is ...
Tan = Opposite/Adjacent
__
Solving for the Opposite side (the height of the balloon), we find ...
Opposite = Adjacent · Tan
height = (310 ft)·tan(22°) ≈ 125.25 ft
Enola's balloon is about 125.25 ft above the ground.
_____
Additional comment
If we assume Enola's angle measurement can have a possible error of ±0.5°, then the corresponding error in the balloon height is more than ±3 ft. It is a bit of nonsense to report the height to the nearest 0.12 inches, (0.01 ft).

-10x19=2x2 please do explanation
Answer:
x=0 or x=−95
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−190x=2x²
Step 2: Subtract 2x² from both sides.
−190x−2x²=2x²−2x²
−2x²−190x=0
Step 3: Factor left side of equation.
(−2x)(x+95)=0
Step 4: Set factors equal to 0.
−2x=0 or x+95=0
x=0 or x=−95
[tex]~~~~2x^2 =-10 \times 19\\\\\implies 2x^2 = -190\\\\\implies x^2 = -\dfrac{190}2\\\\\implies x^2 = -95\\\\\implies x = \pm\sqrt{-95}\\\\\implies x = \pm \sqrt{-1}\sqrt{95}\\\\\implies x = \pm i\sqrt{95}[/tex]
