Can someone please help me with this

Answer:

5.08 years

Step-by-step explanation:

We are to solve for time using compound interest formulas

For Hailey

Principal = $200

Amount = Double of Principal = $4000

Rate = 2 3/8% = 2.375.

Time = ?

Hence,

First, convert R as a percent to r as a decimal

r = R/100

r = 2.375/100

r = 0.02375 per year,

Then, solve the equation for t

t = ln(A/P) / r

t = ln(4,000.00/2,000.00) / 0.02375

t = 29.185 years

≈ 29.19 years

For Sophie

Principal = $200

Amount = Double of Principal = $4000

Rate = 2 7/8% = 2.875

Time = ?

First, convert R as a percent to r as a decimal

r = R/100

r = 2.875/100

r = 0.02875 per year,

Then, solve the equation for t

t = ln(A/P) / n[ln(1 + r/n)]

t = ln(4,000.00/2,000.00) / ( 365 × [ln(1 + 0.02875/365)] )

t = ln(4,000.00/2,000.00) / ( 365 × [ln(1 + 7.8767E-5)] )

t = 24.11 years

How much longer would it take for Hailey's money to double than for Sophie's money to double?

For Hailey it takes 29.19 years

For Sophie it takes 24.11 years

We find the difference

= 29.19 - 24.11

= 5.08 years

Therefore, it would take 5.08 years for Hailey's money to double than Sophie

Step-by-step explanation:

Answer:

F(x) = x^2+3

Step-by-step explanation:

B. F(x) = x² + 3 is the correct answer.

A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.

Horizontal translation: g(x)=f(x+c).

The graph is translated c units to the left if c>0 and c units to the right if c<0.

Vertical translation: g(x)=f(x)+k.

The graph is translated k units upward if k>0 and k units downward if k<0.

Since F(x) has the same shape as G(x) = x^2, but it is shifted up 3 units, we can write:

F(x) = G(x) + 3

F(x) = x² + 3

Therefore, the correct answer is B. F(x) = x² + 3.

Hello, I Am BrotherEye

Answer:

Multiply total meters by 100 to get total centimeters:

6 meters x 100 = 600 centimeters.

Now divide total centimeters by 2.554 to get total inches:

600 centimeters / 2.54 = 236.22 inches.

Rounded to the nearest inch = 236 inches.

Step-by-step explanation:

*Important!

You multiply the length of the value by 39.37

Meaning that if you have 6 meters you would

      Multiply it by 39.37 and get 236.22 inches. Please remember these rules for they will assists you in the future.

Answer:

Sammy would have 16 friends.

Step-by-step explanation:

Let total number of friends be x, each friend gets 2 balls, this can be denoted as 2x balls.

The final relation can be expressed as:

40 (total number) =2x+8 , here 8 is the remainder after distribution.

Now we can solve for x

40=2x+8

40−8=2x

32=2x

x=16

Answer:

16 friends

Step-by-step explanation:

40 balls - 8 remaining = 32 balls in total

32 b in total / 2 balls each = 16 friends

You don't have to use the equation unless you want to check yourself.

Answer:

y = -1/5x - 2

Step-by-step explanation:

All you need is a perpendicular slope and any y-intercept.

Perpendicular slope is a negative reciprocal so:

5 → -1/5

y-intercept doesn't matter so:

y = -1/5x - 2

Answer:

y= -1/5x +4

Step-by-step explanation:

To find a perpendicular line, you need the negative reciprocal of the slope, in this case it is 5 and -1/5.

Answer:

n = -7

Step-by-step explanation:

n - 7/4 = 35/12 + 5/3n

subtract n from both sides of the equation:

-7/4 = 35/12 + 2/3n

convert -7/4 to -21/12:

-21/12 = 35/12 + 2/3n

add 21/12 to both sides:

0 = 56/12 + 2/3n

convert 2/3n to 8/12n:

0 = 56/12 + 8/12n

subtract 56/12 from each side:

8/12n = -56/12

multiply both side by 12:

8n = -56

divide both sides by 8:

n = -7

Step-by-step explanation:

We can use a proportion to answer this question:

64 represent the 100% of the games

x : 100 = 16 : 64

x = (16*100)/64 = 1600/64 = 25%

Answer:

Option A

Step-by-step explanation:

The unit volume explains it all.

Volumes are measured in units of length cubed. This also is the volume occupied by unit cubes.

By unit cubes, I meant, view the photo above

The volume of an object's says, how many of these cubes will fill that object.

It may not necessarily by a whole number.

So, the answer is Option A

Answer:

A

Step-by-step explanation:

volume of a cylinder:

[tex]V=\pi r^2h[/tex]

where r = radius and h = height

We are given the volume (V) and the height (h) and we need to find the radius (r).

To find the radius we are going to want to plug in the given values into the formula for volume of a cylinder and solve for r

so, * plug in given values *

[tex]400= \pi r^28[/tex]

Now we solve for r

step 1 take the square root of each side

[tex]\sqrt{400} =20\\\sqrt{\pi r^28} =\sqrt{\pi } 4*r\\[/tex]

now we have [tex]20=\sqrt{\pi } 4*r[/tex]

step 2 divide each side by sqrt (π) 4

[tex]\frac{20}{\sqrt{\pi } 4} =3.989 \\\\\frac{\sqrt{\pi } 4*r}{\sqrt{\pi } 4}=r\\[/tex]

we're left with r = 3.989

Finally we round to the nearest whole number and get that the answer is A.4

Step-by-step explanation:

Use the distance formula to calculate XY, then equate to 10

d = [tex]\sqrt{x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = X(a -5, - 2a) and (x₂, y₂ ) = Y(a + 1, 2a)

XY = [tex]\sqrt{(a +1-(a-5))^2+(2a-(2a))^2\\}[/tex]

     = [tex]\sqrt{(a+1-a+5)^2+(4a)^2}[/tex]

     = [tex]\sqrt{6^2+16a^2}[/tex] , then

[tex]\sqrt{36+16a^2}[/tex] = 10 ( square both sides )

36 + 16a² = 100 ( subtract 36 from both sides )

16a² = 64 ( divide both sides by 16 )

a² = 4 ( take the square root of both sides )

a = ± [tex]\sqrt{4}[/tex] = ± 2
