Answer:

20 weeks

Step-by-step explanation:

The calculation of The number of weeks it will take to save £360 is given below:

Now  $250 should be divided into a ratio of 3:2

He keeps = 150

And, he gives her = 100

As he saves 12% of his share

i.e.

= 12% of 150

= 18

Now the number of weeks is

= 360 ÷ 18

= 20 weeks

Answer:

A

Step-by-step explanation:

its hard to explain but pretty much if you didn't know the ^x+1 is the x intercept except when its graphed its no marked at (1,0) its mark ate (-1,0) because it always takes the inverse

if you go over to the right 3 then your adding 3 to the x intercept or subtracting 3 from ^x+1 so it would be ^x-2

the y intercept part is easy all you have to do is subtract 2 from the y intercept so it would be +2

hope this helps :D

Step-by-step explanation:

Me + The upcoming championship high school football game is a big deal in your little town. The problem is, it is being played in the next biggest town, which is two hours away! To get as many people as you can to attend the game, you decide to come up with a ride-sharing app, but you want to be sure it will be used before you put all the time in to creating it. You determine that if more than three students share a ride, on average, you will create the app.

You conduct simple random sampling of 20 students in a school with a population of 300 students to determine how many students are in each ride-share (carpool) on the way to school every day to get a good idea of who would use the app. The following data are collected:

6 5 5 5 3 2 3 6 2 2

5 4 3 3 4 2 5 3 4 5

You and your partner will construct a 90% confidence interval and 95% confidence interval for the mean number of students who share a ride to school, then you will compare and interpret the results.

Part A: Decide which partner will construct each confidence interval, and then state the parameter and check the conditions.

Part B: Construct the confidence interval. Be sure to show all your work, including the degrees of freedom, critical value, sample statistics, and an explanation of your process.

Part C: Interpret the meaning of the confidence interval, and describe the difference in the width of the interval and the margin of error.

Part D: Use your findings to explain whether you should develop the ride-share app for the football game. = My brain hurts!!!

Step-by-step explanation:

A camera is positioned 5000 ft from the base of a rocket launching pad. the angle of elevation of the camera has to change at the correct rate in order to keep the rocket in sight. also, the mechanism for focusing the camera has to take into account the increasing distance from the camera to the rising rocket. let's assume the rocket rises vertically and its speed is 800 ft/s when it has risen2548 ft. (round your answers to three decimal places.)

Answer: B

Step-by-step explanation:

We are given an angle and a distance, and to solve for the height we need to make a triangle.

First, I'm going to assign sides to the triangle:

Side a: This is going to be the distance from the camera to the launch pad.

Side b: This is going to be the distance from the launch pad to the rocket (the rocket's height)

Side c: This is going to be the distance from the rocket to the camera (this is the hypotenuse of the triangle)

Now that we have sides, we can solve for the height. The height is the distance from the launch pad to the rocket, so it will be side b. We know that the camera is 5000 ft away from the launch pad, so we can say that side a is 5000 ft. It also tells us the camera is angled up at 27 degrees, so we can say angle B is 27 degrees.

We have a known side that length that is adjacent to a known angle inside of a right triangle, and we want to find the length of the opposite side. In this situation we can use the function tangent.

tan(theta) = opposite / adjacent

If we plug values into this equation we get:

tan(B) = b / a

tan(27 degrees) = b / 5000

b = tan(27 degrees) * 5000

b = 2547.627

b rounded to the nearest foot is 2548 ft, which is answer B

The vertical asymptotes are x= 0 and x = -1 option (D) and option (F) are correct.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a function:

F(x) = (x-5)/3x(x+ 1)

To find the vertical asymptotes:

3x = 0

or

x = 0

x + 1 = 0

or

x = -1

Thus, the vertical asymptotes are x= 0 and x = -1 option (D) and option (F) are correct.

Answer:

Surface area of a cube = 384 mm²

Step-by-step explanation:

Surface area of a cube = 6 s²

Where

s = side length of the cube

s = 8 mm

Surface area of a cube = 6 s²

= 6 * 8²

= 6 * 64

= 384 mm²

Surface area of a cube = 384 mm²

Answer:

The answer is "C" 384 mm²

Step-by-step explanation:

First, I decided to determine the vertical asymptote! You can determine the vertical asymptote by taking the denominator and setting it equal to zero.

−4x+4=0

−4x=−4

x=1

There's a vertical asymptote at x=1.

Now for the horizontal asymptote! The horizontal asymptote is determined by looking at the leading coefficients in the numerator and denominator. Here's a helpful visual.

content://com.cryptotab.android.FileProvider/images/screenshot/16159519510813476709092178134526.jp

In our case, the leading coefficient in the numerator (x2) is larger than the leading coefficient in the denominator (−4x). This means there is no horizontal asymptote!

In some cases, a slant asymptote may be present in a graph. These are sometimes present in graphs that have a stronger leading coefficient in the numerator than the denominator. To determine the slant asymptote, we need to divide the numerator by the denominator.

content://com.cryptotab.android.FileProvider/images/screenshot/16159520052041557972364765603410

The slant asymptote is y=−x4−1

Holes are determined by finding numbers that when plugged into x, return undefined. On a graphing calculator these values will give us an error. Luckily for us, there are no holes, so we can move on.

X-intercepts are values that make the numerator equal zero. We can find these by setting the numerator equal to zero and solving.

x2+3x=0

x(x+3)=0

x+3=0

x=−3

Another number that makes the numerator equal zero is, well, zero!

x2+3x=0

(0)2+3(0)=0

0=0

So we know our x-intercepts are 0 and -3.

To find the y-intercepts, set x equal to zero and solve the equation!

y=x2+3x−4x+4

y=(0)2+3(0)−4(0)+4

y=04

y=0

So we have a y-intercept at y=0!

Answer:

angular velocity = 12π Radians per second

Step-by-step explanation:

The angular velocity is a measure of the rotation/revolution speed of an object, relative to another point.

In order to present the answer in radians per second, let us first establish the relationship between radians and rotations/revolution.

one complete revolution = 360° = 2π Radians

∴ 1 roration = 2π Radians

12 rotations = 12 × 2π Radians = 24π Radians

Angular velocity in radians = 24π Radians in 2 seconds

Now let us convert to radians per seconds.

24π Radians = 2 seconds

2 seconds = 24π Radians

∴ 1 second = (24π Radians) ÷ 2

1 second = 12π Radians

∴ angular velocity = 12π Radians per second

Mean of the data is 62.12, median is 60, mode is 53, range is 32, Q3 is 69.

Mean is the sum of numbers divided by the numbers. It is also known as average.

Fow calculating mean we have to find sum of  numbers which is calculated in figure as 1553.

Mean=1553/25=62.12

Mode is basically the number having higher frequency which is 53.

Median is[ (n+1/2)th term,(n/2)th term]/2

=(60+60)/2

= 60.

Range is basically the difference of smallest number and largest number divided by 2=82-49=32

Q3=3(N+1)/2

=3(25+1)/2

=18.5th term which is 69.

Hence mean of the data is 62.12, median is 60, mode is 53, range is 32, Q3 is 69.

Answer:

The correct solution is "x = -5 and x = -8".

Step-by-step explanation:

The given equation is:

⇒ [tex]x^2+13x+40=0[/tex]

On factorizing the above equation, we get

⇒ [tex]x^2+5x+8x+40=0[/tex]

On taking "x" common, we get

⇒ [tex]x(x+5)+8(x+5)=0[/tex]

⇒         [tex](x+5)(x+8)=0[/tex]

Now,

⇒                       [tex]x+5=0[/tex]

On subtracting "5" from both sides, we get

⇒                 [tex]x+5-5=0-5[/tex]  

⇒                             [tex]x=-5[/tex]

Or,

Answer:

a) 84π b) 109.2π

Step-by-step explanation:

The formula to find this is v=πr^2h/3

r=d/2. so the radius (r) is 6 because you have to divide the diameter (12) by 2. and the height is 7. so, 6^2=36 and 36x7=252.

252/3=84

and because the question is asking for the EXACT value, you need to just put the pi symbol next to it. Final answer for a is 84π

B) you need to find 30% of 84, which is 25.2 and add it to 84, and you will get 109.2! Final answer is 109.2π.
