Step-by-step explanation:

Answer:

x2 =  -0.600000

x3 = -0.521600

Step-by-step explanation:

Given the formula;

xn+1 = (xn)³-5/10

x2 = (x1)³-5/10

Given x1 = -1

x2 = (-1)³-5/10

x2 = (-1-5)/10

x2 = -6/10

x2 = -0.600000

x3 = (x3)³-5/10

Given x3 = -0.6

x3 = (-0.6)³-5/10

x3 = (-0.216-5)/10

x3 = -5.216/10

x3 = -0.521600

Answer:

9 dollars

Step-by-step explanation:

58.5 times .15 = 8.775 which can be rounded up to 9 dollars

If group of college students spent $58.50 for dinner and wanted to leave a 15% tip. Then $9 is the tip.

percentage, a relative value indicating hundredth parts of any quantity.

Given,

A group of college students spent $58.50 for dinner

The students want to leave a tip of 15%.

We need to find how much they has to leave as tip.

Firstly we have to convert 15% to decimal.

We have to divide 15 by 100

15/100

0.15

Now we have to multiply 0.15 with 58.50 to find the 15% of 58.50

0.15×58.50

8.775

9

Hence, $9 is the tip the students has to leave.

Step-by-step explanation:

Answer:

There are many..

One would be y = 4x + 7

The trick is the slope is always the same. The only difference is the y-int. You could make one yourself, just use 4x at the beginning.

Answer:

  y = 4x

Step-by-step explanation:

A parallel line will have the same slope. The given line is written in "slope-intercept form", so the slope is readily identified from the equation.

  y = mx + b . . . . . line with slope m and y-intercept b

  y = 4x -7 . . . . . . line with slope 4 and y-intercept -7

So, the parallel line will be something of the form ...

  y = 4x + b

for any value of b. The simplest is to let b=0. If b=-7, then the lines are coincident, not parallel, so that value must be excluded. Any other value of y-intercept will give a parallel line.

  y = 4x . . . . . parallel line

Answer:

11[tex]\pi[/tex]

Step-by-step explanation:

To find the circumference of a circle, the formula is:

d * [tex]\pi[/tex] = c

We already know the diameter, so we just plug that in:

11 * [tex]\pi[/tex] = c

11[tex]\pi[/tex] = c

Answer:

We are solving for the area so; A=134.16

Step-by-step explanation:

Here is the formula for finding area of a sector:

A = [tex]\pi r^{2}[/tex] × θ° ÷ 360°

where theta is the angle of the sector you wish to find, and r is the radius of the circle.

Substitute the numbers in and you get:

[tex]\frac{25\pi }{2} unit ^{2}[/tex]

You should find 39.26991 as your answer (or any number rounded according to the value of pi)
