Sherrod deposits $500 each year in a savings account earning 3% interest compounded annually. He makes no withdrawals. How much interest will the account earn after 3 years?

Answers

Answer 1

The formula for annual compound interest, including principal sum, is:
A = P (1 + r/n) (nt)

Where:

A = the future value of the investment/loan, including interest
P = the principal investment amount (500)
r = the annual interest rate (.03)
n = the number of times that interest is compounded per year (1)
t = the number of years the money is invested (3)

A=5000(1+.03/1)^1(3)

A=546.36

Interest (I) gained is A-P

I=546.36-500

I=46.36

Explanation:
To get the inverse of a function, we will follow these steps:
1- replace f(x) with y
2- swap the x and y variables
3- solve for y
replace y with f⁻¹(x)

Applying this to the given as follows:
f(x) = 7x - 6

Step 1: replace f(x) with y:
y = 7x - 6

Step 2: swap the x and y variables:
x = 7y - 6

Step 3: solve for y:
7y = x + 6
y = [tex] \frac{x+6}{7} [/tex]

Step 4: replace y with f⁻¹(x):

Q10 Q2.) Find the standard form of the equation of the parabola satisfying the given conditions.

Answers

To solve this problem you must apply the proccedure shown below:

1. You have that the standard form of the equation of the parabola must satisfy the following conditions given in the exercise above:

Focus: (-1,4) and Directrix: y=2

2. Therefore you have:

√(x0-(-1))²+(y0-4)²=|y0-2|
(x0+1)²+(y0-4)²=(y0-2)²

3. When you simplify the expression above and clear y0, you obtain:

y0=y

y=1/4(x²+2x+13)
y=(x²/4)+(x/2)+(13/4)

Therefore, the answer is: y=(x²/4)+(x/2)+(13/4)

The current size of an image on Samuel's computer is shown below: A rectangle is shown. The length of the rectangle is labeled as length equal to 8 inches and the width is labeled as width equal to 10 inches. What are the dimensions of the image at fraction 1 over 2 times its current size

Answers

Length is equal to 4 and width is equal to 5.

You can just divide each by 2.

Answer:

The length and the width of image is 4 inches and 5 inches respectively

Step-by-step explanation:

Given : Length of rectangle is 8 inches

Width of rectangle is 10 inches

To Find: What are the dimensions of the image at fraction [tex]\frac{1}{2}[/tex] times its current size

Solution:

Length of rectangle is 8 inches

Since we are given that the dimensions of the image at fraction [tex]\frac{1}{2}[/tex] times its current size

So, Length of image = [tex]\frac{1}{2} \times 8 = 4[/tex]

Thus the length of image is 4 inches.

Width of rectangle is 10 inches

Since we are given that the dimensions of the image at fraction [tex]\frac{1}{2}[/tex] times its current size

So, width of image = [tex]\frac{1}{2} \times 10 = 5[/tex]

Thus the width of image is 5 inches.

Hence the length and the width of image is 4 inches and 5 inches respectively.

Final answer:

The midpoint between the complex numbers 5-2i and 7+6i is 6 + 2i.

Explanation:

To find the midpoint between two complex numbers, we can use the formula:

Midpoint = (Re(z1) + Re(z2))/2 + (Im(z1) + Im(z2))/2i

Applying the formula to the given complex numbers 5-2i and 7+6i, we have:

Midpoint = (5 + 7)/2 + (-2 + 6)/2i
Midpoint = 12/2 + 4/2i
Midpoint = 6 + 2i

A video posted on the internet is becoming very popular,and the total number of views is increasing by 40% every hour if the video currently has 38,000 views how many views will it have in 2 hours

Answers

Final answer:

The video with an initial 38,000 views will have approximately 74,480 views in 2 hours when it is increasing by 40% every hour.

Explanation:

To calculate the number of views a video will have in 2 hours if it is increasing by 40% every hour, we will use the formula for percentage growth. Initially, the video has 38,000 views. After one hour, the views will be increased by 40%, and after two hours, this new amount will again be increased by 40%. The formula for calculating the number of views after each hour is:

Views after n hours = Initial views × [tex](1 + growth rate)^n[/tex]

Where:

Initial views = 38,000

Growth rate = 40% = 0.40 (as a decimal)

n = number of hours

After 1 hour:

Views after 1 hour = 38,000 × (1 + 0.40)^1

Views after 1 hour = 38,000 × 1.40 = 53,200

After the second hour, we will use the number of views from the first hour to calculate the increase:

Views after 2 hours = 53,200 × [tex](1 + 0.40)^1[/tex]

Views after 2 hours = 53,200 × 1.40 = 74,480

Therefore, the video will have approximately 74,480 views in 2 hours.

Ben runs around the track at a pace of 1 lap every 80 seconds. Sally runs on the track in the opposite direction. The two meet every 30 seconds. How long does it take Sally to run each lap around the track?

Answers

48 seconds, Consider what happens between one time that Ben and Sally meet and the next. During this period Ben runs 30 (seconds)/80 (seconds/lap) = 3/8 of a lap. So Sally runs 5/8 lap in the same time. Her speed is therefore 5/8 (laps)/ 30(seconds) which amounts to 1 (lap)/ 48 (seconds).

ΔABC and ΔXYZ are similar triangles. If BC = x + 7, AC = x + 6, YZ = 4 − x, and XZ = 3 − x, find the value of x.

Answers

Since these triangles are similar, we have proportional sides. We can write that [tex] \frac{x+7}{4-x} = \frac{x+6}{3-x} [/tex]. Solving it, we find that x=-1.5

Answer:

-3/2 or -1.5

Step-by-step explanation:

-3/2 = -1.5

BC = -1.5 + 7 = 5.5

AC = -1.5 + 6 = 4.5

YZ = 4 - (-1.5) = 5.5

XZ = 3 - (-1.5) = 4.5

a band that will be the opening act for a concert charges a $700.00 flat fee as well as 16% of all ticket profits from ticket sales. if the band earned $1,200, how much was made in total ticket sales for the show?

Answers

The band earned $1,200.

1. Subtract the flat fee 1,200-700 =500
2. 500 is what just the band made. Divide that by .16 (16%) to get the total ticket amount... 500 divided by .16 = 3,125

The total ticket amount was $3,125.

Answers

we know that

in the triangle BCD
cos C=8/14
C=arc cos (8/14)-----> C=55.15°

sin C=BD/14---------> BD=14*sin 55.15------> BD=11.49 ft

in the triangle ABC
180=∡A+∡B+∡C
∡A=180-(90+55.15)-----> ∡A=34.85°

tan A=BD/y-------> y=BD/tan A-----> y=11.49/tan 34.85----> y=16.50 ft

the answer is
y=16.50 ft

To solve the exercise shown in the picture attached, you must apply the following proccedure:

1. First, you must apply the Pythagorean Theorem to calculate the heigth of the triangle, as below:

a^2=b^2+c^2
b=√(a^2-c^2)
b=√(14)^2-(8)^2
b=√132
b=11.48

2. Now, you must calculate the angle ∠BC, as below:

Sin(α)^-1=opposite/hypotenuse
Sin(BC)^-1=8/14
∠BC=34.84°

3. Therefore, the angle ∠BA is:
∠BA=90°-34.84°
∠BA=55.15°

4. Then, you have:

Tan(55.15°)=y/11.48
y=16.48

Suppose that the demand equation for a certain item is 1p+1x2−160=0. evaluate the elasticity at 65:

Answers

Price elasticity is defined as [tex]\frac{\Delta(quantity)}{\Delta(price)}[/tex].

Here, the question has omitted to define variables, so we will ASSUME
p=price
x=variable,
and we're given
p+x^2-160=0

We calculate
[tex]\delta{x}/\delta{p}[/tex] by implicit differentiation with respect to p:
1+2x (dx/dp)=0
=>
E(x)=(dx/dp)=-1/(2x)

Therefore the price elasticity at x=65 is
E(65)=1/(2*65) =-1/130 (approximately -0.00769)

The required value of elasticity at x = 65 is -0.007.

Given that,

The demand equation for a certain item is [tex]1p + 1x^{2} -160 = 0[/tex].

We have to determine,

The value of elasticity at 65.

According to the question,

The price elasticity of demand is calculated as the percentage change in quantity divided by the percentage change in price.

Therefore,

Price of elasticity = [tex]\frac{dp}{dx}[/tex]

Calculate change by differentiation with respect to p:

[tex]\dfrac{d(p+x^{2} -160)}{dx}\\\\1 + 2x\frac{dp}{dx} = 0\\[/tex]

Then,

[tex]E(x) = \frac{dp}{dx} = \frac{-1}{2x}[/tex]

Therefore, The elasticity at x = 65 is ,

[tex]E(65) = \frac{-1}{2(65)} = -0.007[/tex]

Hence, The required value of elasticity at x = 65 is -0.007.
