How to estimate the power of digits?

The power of a numeral stands for how many multiples of the number there exist. The base of the number stands for the number itself and lives in front of the exponent. The exponent stands for the smaller number written above and to the right of the base. Positive exponents result in the base value existing multiplied by itself numerous times.

As the exponent exists as a positive integer, exponentiation signifies repeated multiplication.

9 to the 33rd power [tex]$=9* ........*9*[/tex] 33 times

The exponent of the number 9, 33, even named index or power, indicates how many times to multiply the base (9).

Therefore, we can answer what exists 9 to the 33rd power as 9 to the power of 33 = [tex]9^{33}[/tex] to the power of 30903154382632612361920641803529.

at the end of each year at 5% compounded annually to reach his goal of paying
off $430,000 in 10 years.

Answers

For Rob Herndon to achieve his goal of paying off $430,000 in 10 years, he needs to make $34,186.97 at 5% compounded annually.

What is a future value?

A future value refers to a value on a future date based on an assumed growth rate of interest over some period.

The future value can be determined using the FV formula or table.

We can also compute the future value using an online finance calculator as follows:

Data and Calculations:

N (# of periods) = 10 years

I/Y (Interest per year) = 5%

PV (Present Value) = $0

FV (Future Value) = $430,000

Results:

PMT = $34,186.97

Sum of all periodic payments = $341,869.70

Total Interest= $88,130.30

Thus, for Rob Herndon to achieve his goal of paying off $430,000 in 10 years, he needs to make $34,186.97 at 5% compounded annually.

A quadratic equation is an equation in which the highest power of the variable is two.

Yvonne is solving the quadratic equation, which is,

He is solving the above equation by completing the square.

The first step to solving this quadratic equation by completing the square is, Take the constant value 7 at the opposite side of the equation as,

6x² +24x = -7

Here, the number seven was a positive number, which we have changed to negative because this number brings the other side of the equation.

pls help asap, find the height of the cylinder and round to the nearest tenth

Answers

Answer:

h = 2.4

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h  where r is the radius and h is the height

271.4 = pi ( 6)^2 *h

271.4 = 36* pi* h

Letting 3.14 = pi

271.4 = 113.04 h

Divide each side by 113.04

271.4 /113.04 = 113.04h/113.04

2.424805379 = h

Rounding to the nearest tenth

2.4 = h

OR if we use the pi button

271.4 = 36 * pi *h

Divide each side by 36 pi

271.4/36pi = h

h=2.3997

Directions: construct the bisector of the following figures.

Note: please draw them out each on a piece of paper or laptop. Thank you!

Answers

A bisector is the required line that divides a given line or an angle into two equal parts. The required construction of the bisectors is shown in the attachment to this answer.

Bisection is the process in which a given line or angle is divided into two equal parts by constructing the required bisector. Thus the steps to bisect the given arcs are stated below:

For figure 1:

Open the compass to any radius, using point A as the center draw arcs on the reverse side of the given arc AB.Repeat the same process using point B as the center and the same radius as that used in A.Join the intersections of the arcs on the reverse sides of arc AB by a line. Thus the required bisector.

For figure 2:

Open the compass to any radius, using point M as the center draw arcs on the reverse side of the given arc MN.Repeat the same process using point N as the center and the same radius as that used in M.Join the intersections of the arcs on the reverse sides of arc MN by a line. Thus the required bisector.

For figure 3:

Open the compass to any radius, using point A as the center draw arcs on the reverse side of the given arc AB.Repeat the same process using point B as the center and the same radius as that used in A.Join the intersections of the arcs on the reverse sides of arc AB by a line. Thus the required bisector. The point on arc AB through which the bisector intersects is the required point S. The mid point of arc AB.

For figure 4:

Open the compass to any radius, using point A as the center draw arcs on the reverse side of the given arc AB.Repeat the same process using point B as the center and the same radius as that used in A.Join the intersections of the arcs on the reverse sides of arc AB by a line. Thus the required bisector. Repeat the same procedures using points BC.

NB: The point of intersection of the bisectors in relation to arc AC is the radius of the given arc.

Ali rented a truck for one day. There was a base fee of , and there was an additional charge of cents for each mile driven. Ali had to pay when he returned the truck. For how many miles did he drive the truck?

Answers

Using a linear function, it is found that he drove the truck for 240 miles.

What is a linear function?

A linear function is modeled by:

y = mx + b

In which:

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

Researching the problem on the internet, there was a base fee of $18.99, which is the y-intercept, and there was an additional charge of 75 cents for each mile driven, which is the slope, hence the cost function for m miles driven is given by:

C(m) = 18.99 + 0.75m.

He paid $199, hence the number of miles he drove is found as follows:

C(m) = 18.99 + 0.75m.

199 = 18.99 + 0.75m

m = (199 - 18.99)/0.75

m = 240 miles.

What are the equation of the line of best fit and the absolute value of the correlation coefficient?

Answers

The equation of the line of best fit is y = -4.75X + 88.6 and the absolute value of the correlation coefficient is 0.906

The equation of the line of best fit

The data values of the question are as follows:

(1, 88), (2, 75), (3, 71), (4, 69), (5,66), (6, 68), (7, 50)

To determine the equation of the line of best fit, we make use of a graphing calculator.

From the graphing calculator, we have the following summary:

Sum of X = 28Sum of Y = 487Mean X = 4Mean Y = 69.5714Sum of squares (SSX) = 28Sum of products (SP) = -133The value of R is: -0.906.

The line of best fit equation is

y = bx + a

Where

b = SP/SSX = -133/28 = -4.75

a = MY - bMX = 69.57 - (-4.75*4) = 88.57143

So, we have:

y = -4.75X + 88.57143

Approximate

y = -4.75X + 88.6

Hence, the equation of the line of best fit is y = -4.75X + 88.6

The absolute value of the correlation coefficient

In (a), we have:

The value of R is: -0.906.

This represents the correlation coefficient.

The absolute value is

|R| = 0.906.

Hence, the absolute value of the correlation coefficient is 0.906

The Volume of the composite figure = Volume of the rectangular prism + Volume of the square pyramid = 4,050 ft³.

How to Find the Volume of a Composite Figure?

The composite figure shown is composed of a square pyramid and a rectangular prism. To find the volume of the composite figure, find the volume of the square pyramid and the volume of the rectangular prims respectively.

Volume of the square pyramid = 1/3(B)(h), where:

Base area (B) = (l)(w) = (15)(15)

h = 9 ft

Volume of the square pyramid = 1/3(225)(9)

Volume of the square pyramid = 675 ft³.

Volume of the rectangular prism = (length)(width)(height)

Volume of the rectangular prism = (15)(15)(15)

Volume of the rectangular prism = 3,375 ft³.

Answers

Considering the definition of least common multiple, this means that smallest number of packages of each they can buy is 60.

Least common multiple

A number is a multiple of another when it contains it exactly n times. In other words, the multiples of a number are the ones you get when you multiply one number by another.

The least common multiple allows us to know what is the smallest number that is a multiple of a certain set of numbers.

One procedure for calculating the least common multiple is to break each number into prime factors. Then the common and uncommon factors are raised to the highest exponent, which must be multiplied.

Smallest number of packages

To calculate the smallest number of packages of each they can buy, you calculate the least common multiple.

First, the decomposition of the numbers into prime factors is carried out:

15= 3×5

12= 2×2×3= 2²×3

Then, the least common multiple is calculated as 2²×3×5

Solving, the least common multiple between 12 and 15 is 60.

Finally, this means that smallest number of packages of each they can buy is 60.
