As m ∠ COD = 90°, then the angle COD is a right angle.

According to geometry, angles are generated by semirrays with a common point. There are different kinds of angles concerning its measure:

Based on all the information given by the protractor, we find that the measure of the angle AOD is:

m ∠ COD = m ∠ AOD - m ∠ AOC

If we know that m ∠ AOD = 115 ° and m ∠ AOC = 25°, then the measure of the angle COD is:

m ∠ COD = 115° - 25°

m ∠ COD = 90°

As m ∠ COD = 90°, then the angle COD is a right angle.

30 = m<1 = m<2

m<1 is equals to m<2 because these two angles are transitive property.

given that m<1 = 30° and m<2 = 30°.

m<1 = 30

m<2 equals to m<1

m<2 = 30 can be obtained by substituting 30 into the second equation.

The proof is now complete.

The Transitive Property of Equality can also be used, which asserts that if X = Y and Y = Z, then X = Y = Z. In other words, if one number is equal to another, and that other number is equal to a third, then all three numbers must be the same.

thus, 30 = m<1 = m<2, m<1 is equals to m<2 because these two angles are transitive property.

She can have 60 reading list to plan to read the 6 novels that she wants to read including the 'in the chest of a woman' in the list.

We are given that:

Number of novels that Julia wants to read = 6

She plans to read = 4

1 novel is fixed that is "in the chest of a woman' by Efo Kodjo"

We need to tell the number of possible reading list that she can have.

We will use permutation for it

By using permutation, we get that:

Number of reading list = 1 × 5 × 4 × 3

Number of reading list = 5 × 12

Number of reading list = 60 lists

Therefore, she can have 60 reading list to plan to read the 6 novels that she wants to read including the 'in the chest of a woman' in the list.

Chebyshev's Theorem

When the distribution is not normal, Chebyshev's Theorem is used. It states that:

          [tex]P = 100(1-\frac{1}{k^2} )[/tex]

Chebyshev's Theorem is used to determine that:

For the 1sr item, we have to find k at P = 56,

          [tex]P = 100(1-\frac{1}{k^2} )[/tex]  

          [tex]56 = 100(1-\frac{1}{k^2} )[/tex]

          0.56 = 1 - [tex]\frac{1}{k^2}[/tex]

            [tex]\frac{1}{k^2} = 0.44[/tex]

            k² = 1/0.44

            k = [tex]\sqrt{\frac{1}{0.44} }[/tex]

Answer:

no

Step-by-step explanation:

The amount saved by repaying the loan early is $831.25

The amount of discount received by purchasing supplies is $3,500

The net amount saved by purchasing supplies rather than repaying loan is $2,668.75

What is ordinary interest?

Ordinary interest is the interest computation that is based on 360-day a  year count rather than 365-day year count, hence, in determining the amount saved by paying $35,000 out of the amount due to Citizens Bank, we time-apportion the interest for 90 days with respect to 360 days not 365 days.

Amount saved in interest=$35,000*9.5%*90/360

Amount saved in interest=$831.25

Using the $35,000 to purchase serving supplies, 10% discount is given off the normal cost of $35,000

Amount saved with discount=10%*$35,000

Amount saved with discount=$3,500

The difference between discount on supplies and interest saved=$3,500-$831.25

The difference between discount on supplies and interest saved=$2,668.75

The other factors to consider before making the final decisions include, the fact the loan is more important than the supplies because the loan relates to the firm's financing rather than operational needs of supplies

Secondly, the amount saved in interest may be more if another loan of $35,000 can be borrowed elsewhere with significant lower interest rates

The total amount saved by the James is: $330.

The relationship between two expressions is expressed by the word equation. It employs many mathematical symbols, including greater-than, less-than, and equal.

The amount James has saved, according to the query, is $15 each week.

It is now time to generate the table that shows how the variable "x" and the number of weeks relate to one another.

The following are the possible possibilities for the necessary parameters "x" and "y":

x = [1 2 3 4]

y = [15 30 45 60]

The last formula may now be written as y = 15x.

Answer: Tane needs to work 8 hours per week while Pete needs to work 5 hours per week

Step-by-step explanation:

T=Tane. P=Pete

5*13=65

T+P=65

15T+16P=1000

T=65-P

15(65-P)+16P=1000

975-15P+16P=1000

975+P=1000

P=25 hours for 5 weeks

T=65-25

Herein we find that the coordinates of the midpoint and part of the coordinates of the ends of the line segment are known. We must determine the values of the missing coordinates by the midpoint formula:

0.5 · (x, 7) + 0.5 · (-1, y) = (3, 5)

Answer: f'(11)=1/6

Step-by-step explanation:

f(x)=sqrt(x-2)

f(x)=(x-2)^1/2

f'(x)=1/2 * (x-2)^(1/2-1)

f'(x)=1/2 * (x-2)^(-1/2)

f'(11)=1/2 * (11-2)^(-1/2)

f'(11)=1/2 * (9)^(-1/2)

f'(11)=1/2 * (9)^(1/2 * (-1))

f'(11)=1/2 * (9^1/2)^(-1)

f'(11)=1/2 * (3)^(-1)

f'(11)=1/2 * 1/3

f'(11)=1*1/(2*3)

f'(11)=1/6

Using the definition of the derivative, we have

[tex]\displaystyle f'(11) = \lim_{x\to11} \frac{\sqrt{x-2} - \sqrt{11-2}}{x - 11} = \lim_{x\to11} \frac{\sqrt{x-2} - 3}{x - 11}[/tex]

Rationalize the numerator.

[tex]\displaystyle \frac{\sqrt{x-2}-3}{x-11} \cdot \frac{\sqrt{x-2}+3}{\sqrt{x-2}+3} = \frac{\left(\sqrt{x-2}\right)^2 - 3^2}{(x-11)\left(\sqrt{x-2}+3\right)} = \frac{x - 11}{(x - 11) \left(\sqrt{x-2} + 3\right)}[/tex]

If [tex]x\neq11[/tex], we can simplify the limit to

[tex]\displaystyle f'(11) = \lim_{x\to11} \frac{x-11}{(x-11)\left(\sqrt{x-2}+3\right)} = \lim_{x\to11} \frac1{\sqrt{x-2} + 3}[/tex]

The function in the remaining limit is continuous at [tex]x=11[/tex], so we end up with

[tex]\displaystyle f'(11) = \frac1{\sqrt{11-2} + 3} = \boxed{\frac16}[/tex]

a) The average rate of change on that interval is 0.1

b) as we increase the speed in the interval [60, 80], the fuel economy increases at a rate of 0.1

For any function f(x), the average rate of change on an interval (a, b) is given by:

(f(b) - f(a))/(b - a)

In this case, the function is:

F(x) = −0.005x^2 + 0.8x + 12

And the interval is [60, 80]

Then we have:

F(60) =  −0.005*60^2 + 0.8*60 + 12 = 42

F(80) = −0.005*80^2 + 0.8*80 + 12 = 44

Then the average rate of change on that interval is:

R = (44 - 42)/(80 - 60) = 0.1

b) What does that rate means?

F(x) relates the fuel economy and x the speed of the vehicle.

Taking into account the definition of Scientific notation,  the correct answer is the first option: the total mass of the paperclips in the box is 4.338×10¹ mg.

Scientific notation is a quick way to represent a number using powers of base 10.

The numbers are written as a product:

a×10ⁿ

where:

Total mass of the paperclips

In this case, you know that:

To know the total mass of the paperclips in the box, you must multiply the number of paperclips in the box by the mass of each paperclip:

7.23×10⁴×6.0×10⁻⁴

To multiply numbers in scientific notation, you multiply the numbers that are not powers of 10 (the numbers previously called "a") and add the exponents of 10.

(7.23×6.0)×10⁴⁻⁴= 43.38×10⁰= 4.338×10¹ mg
