Explanation:

Always start with what is given. The last statement is the thing we want to prove.

Complementary angles add to 90 degrees. They form a right angle.

When "definition of congruence" is mentioned, we go from two angles being congruent to having them be of the same measure. It's a slight change of notation.

Vertical angles form whenever we cross two lines to form an X shape. The vertical angles are opposite one another, and always congruent.

The substitution property is the idea of replacing one thing with something it is equivalent to. In other words, we plug in the item.

Notice on line 2, if we replace "angle 1" with "angle 4" (valid because the two angles are congruent), and then replace "angle 2" with "angle 3", then we get the result on line 7.

Answer:

1. Given.

2. Definition of complementary angles.

3. Given.

4. Definition of congruent angles.

5. Vertical Angles Theorem.

6. Definition of congruent angles.

7. Substitution Property of Equality.

8. Definition of complementary angles.

Step-by-step explanation:

Statement 1

∠1 and ∠2 are complementary.

Reason:  Given.

Statement 2

m∠1 + m∠2 = 90°

Reason:  Definition of complementary angles.

Complementary angles are two angles that sum to 90°.  Therefore, if ∠1 and ∠2 are complementary, then their measures must sum to 90°.

Statement 3

∠1 ≅ ∠4

Reason:  Given.

Statement 4

m∠1 = m∠4

Reason:  Definition of congruent angles.

Congruent angles are angles with exactly the same measure.  As angle 1 is congruent to angle 4, then their measures are equal.

Statement 5

∠2 ≅ ∠3

Reason:  Vertical Angles Theorem.

Vertical angles are always congruent.  

Statement 6

m∠2 = m∠3

Reason:  Definition of congruent angles.

Congruent angles are angles with exactly the same measure.  As angle 2 is congruent to angle 3, then their measures are equal.

Statement 7

m∠4 + m∠3 = 90°

Reason:  Substitution Property of Equality.

For all numbers a and b, if a=b, then a may be replaced by b in any equation or expression.

As m∠2 = m∠3 and m∠1 = m∠4, replacing them in m∠1 + m∠2 = 90° gives m∠4 + m∠3 = 90°.

Statement 1

∠3 and ∠4 are complementary.

Reason:  Definition of complementary angles.

Complementary angles are two angles whose sum is 90°.  Therefore, if the sum of m∠4 and m∠3 is 90°, this means that ∠4 and ∠3 must be complementary.

There are 420 arrangements for seven-digit numbers that can be formed with the digits of 2201213 by permutation.

The term permutation is simply the process of arrangement or selection of objects. It involves each of several possible ways in which a set or number of things can be ordered or arranged.

We can apply the formula for permutation;

[tex]p(n,r) = \frac{n!}{(n - r)!}[/tex]

where n = total number of object and r = number of objects selected.

Total number of digits = 7

number of the digit 2 = 3

number of the digit 1 = 2

number of the digit 0 = 1

number of the digit 3 = 1

so the permutation for the digits 2201213 is calculated as;

7!/(3! × 2! × 1! × 1!)

(7 × 6 × 5 × 4 × 3!)/(2 × 3!) {cancel out 3! with 3! and 4 with 2}

In order to get the total amount $91,000 at the end of the 7 year, the interest rate is 2.2% on compound interest basis.

Compound Interest:

The general form to calculate the compound interest is written as,

A = P(1 + r/n)ⁿˣ

where

A = Accrued amount (principal + interest)

P = Principal amount

r = Annual nominal interest rate as a decimal

n = number of compounding periods per unit of time

x = time in decimal years

Given,

Naomi is going to invest $78,000 and leave it in an account for 7 years. Assuming the interest is compounded daily.

Here we need to find the  nearest hundredth of a percent, would be required in order for Naomi to end up with $91,000.

Here we have to solve for rate r as a decimal

[tex]r = n[(A/P)^{1/nt} - 1][/tex]

r = 365 × [(91,000.00/78,000.00)1/(365)(7) - 1]

r = 0.022022202

Then convert r to R as a percentage

R = r * 100

R = 0.022022202 * 100

R = 2.202%/year

Therefore, the interest rate required to get a total amount of $91,000.00 from compound interest on a principal of $78,000.00 compounded 365 times per year over 7 years is 2.202% per year.

The average rate of change of the height as a function of time from 1 to 2 is 96

Rate of change

Rate of change defines the ratio that compares the change in values of the y variables to the change in values of the x variables.

Given,

The height (in feet) of a falling object with an initial velocity of 48 feet per second launched straight upward from the ground is given by h(t) = 16t² + 48t where is time (in seconds).

Here we need to find the average rate of change of the height as a function of time from 1 to 2.

In order to find the average rate of change we need to find the value for the time 1 and time 2.

For, that we have to apply the value on the function,

First, we have to apply the value of t as 1, then we get the value of the function as,

h(1) = 16(1)² + 48(1)

h(1) = 16 + 48

h(1) = 64

Now, we have to apply the value of t as 2, then we get,

h(2) = 16(2)² + 48(2)

h(2) = (16 x 4) + 96

h(2) = 64 + 96

h(2) = 160

Therefore, the average rate of change is,

=> rate of change = (160 -64) / 2 - 1

=> rate of change = 96

Therefore, the average rate of change from 1 to 2 is 96.

The area between the curve y = x^2 - 3x for x between 1 and 8 is 1343 / 3 square units.

First, let us understand the area under the curve:

A definite integral between two points is used to calculate the area under a curve between them. Integrate y = f(x) between the limits of a and b to determine the area under the curve y = f(x) between x = a and x = b. This area can be estimated by integrating with specified limitations.

We are given:

y = x^2 - 3x

We need to find the area between the curve y = x^2 - 3x for x between 1 and 8.

Now,

Integrate the given function:

Integration y = Integration  x^2 - Integration 3x

y = [x^(2 + 1) / (2 + 1)] ^ 8 _1 - [3x^(1 + 1) / (1 + 1)] ^ 8 _1

y = [x^3 / 3] ^ 8 _1 - [3x^2 / 2] ^ 8 _1

y = [8^3 / 3 - 1^3 / 3] - [3 * 8^2 / 2 - 1 * 8^2 / 2]

y = [512 / 3 - 1 / 3] - [96 - 32]

y = 1535 / 3 - 64

y = 1535 - 192 / 3

y =  1343 / 3 square units.

So, the area is 1343 / 3 square units.

y = mx + b

Where:

In order to determine Cassidy’s profit, we would have to calculate the cost of the containers of popcorn by using this mathematical expression:

Note: the price tag for a container of popcorn is one dollar and fifty cents.

Cost of containers = revenue - total profit

Cost of containers = 1.50(15) - 5.50

Cost of containers = 22.5 - 5.50

Cost of containers = $17.00

Therefore, the linear function which models Cassidy’s profit is given by:

y = 1.50x - 17

If Cassidy sells all of the popcorn, his profit is given by:

Cassidy’s profit, y = 1.50x - 17

GIven that we require the limit given as  [tex]\lim_{x \to 1} \frac{sinx - sin1}{x - 1}[/tex]

So, substituting the value of x = 1 into the given equation, we have that

[tex]\lim_{x \to 1} \frac{sinx - sin1}{x - 1} = \frac{sin1 - sin1}{1 - 1} \\= \frac{0}{0}[/tex]

Since 0/0 is one of the inderterminate forms, we use the L'hopital's rule to find the limit of the given function.
