Answer:You can use the concept of conservation of total mechanical energy (neglecting the air resistance).

So, initially total mechanical energy = gravitational potential energy (kinetic energy is zero because initially there is no velocity).

Final total mechanical energy = kinetic energy (gravitational potential energy is zero because height has become zero).

So, initial mechanical energy = Final mechanical energy

Answer: Sometimes, two angles are a part of each other or are connected to each other. These angles are called angle pairs.

Let's look at two special types of angle pairs, supplementary angles or complementary angles.

Supplementary angles are two angles whose sum is equal to 180∘. In other words when you add the measure of one angle in the pair with the other angle in the pair, they equal 180 degrees.

These two angles are supplementary because together they form a straight line. You can also tell that they are supplementary because when you add their angle measures the sum is equal to 180 degrees.

120+60=180∘

Complementary angles are a pair of angles whose sum is 90∘. Here is an example of complementary angles.

If you add up the two angle measures, the sum is equal to 90 degrees. Therefore, the two angles are complementary.

You can find missing angle measures by using information about supplementary and complementary angles.

Let's look at an example.

Find the measure of x.

First, identify that these two angles are supplementary. They form a straight line. The total number of degrees in a straight line is 180. Therefore, you can write the following equation to solve.

130+xx=180=50∘

The missing angle is equal to 50∘.

Here the two angles are complementary. Therefore the sum of the two angles is equal to 90 degrees. Write an equation and solve for the missing angle measure.

75+xx=90=15∘

The missing angle measure is equal to 50∘.

Examples

Example 1

Earlier, you were given a problem about Paul and the house.

He has an angle pair that is formed by two 90 degree angles. What type of angle pair is formed when two 90 degree angles are combined?

First,add the two angles to calculate their sum.

90 + 90 = 180

Then, identify which angle pair adds up to 90 degrees.

Supplementary angles

The answer is that the pair are supplementary angles.

Example 2

Identify the angle pair as complementary or supplementary.

First, add the two angles to calculate their sum.

75 + 105 = 180

Then, identify which angle pair adds up to 180 degrees.

Supplementary angles

The answer is supplementary angles.

Write whether each pair is complementary or supplementary.

Example 3

Identify the angle pair as complementary or supplementary.

If the sum of the angles is equal to 180 degrees.

First, identify which angle pair adds up to 180 degrees.

Supplementary angles

The answer is supplementary angles.

Example 4

Identify the angle pair as complementary or supplementary.

If one angle is 60 degrees and the other angle is 120 degrees.

First, add the two angles together to find the sum.

60 + 120 = 180

Then, identify which angle pair adds up to 180 degrees.

Supplementary angles

The answer is supplementary angles.

Example 5

Identify the angle pair as complementary or supplementary.

First, add the two angles to calculate their sum.

30 + 60 = 90

Then, identify which angle pair adds up to 90 degrees.

Complementary angles

The answer is that the pair are complementary angles.

Calculate the area of the parallelogram, giving your answer correct to 3 significant figures.

Answers

Answer:

114 units²

Step-by-step explanation:

The opposite sides of a parallelogram are congruent, so

AB = CD , that is

13x - 7 = 5x + 9 ( subtract 5x from both sides )

8x - 7 = 9 ( add 7 to both sides )

8x = 16 ( divide both sides by 8 )

x = 2

Then

5x + 9 = 5(2) + 9 = 10 + 9 = 19

3x = 3(2) = 6

The area (A) of a parallelogram is calculated as

A = bh ( b is the base and h the perpendicular height ), thus

A = 19 × 6 = 114 units²

The value of y varies jointly with the values of x and z When x = 4 and z = 10, the value of y is 360.
What is the value of y when x 5 and z = 12?
A. 540
B. 9
C. 153
D. 450

Answers

Answer:

A

Step-by-step explanation:

Joint variation is given by:

[tex]y=kxz[/tex]

Where k is some constant.

We are given that y = 360 when x = 4 and z = 10. Therefore:

[tex]360=k(4)(10)[/tex]

Solving for k:

[tex]40k=360\Rightarrow k=9[/tex]

Therefore, our equation is:

[tex]y=9xz[/tex]

Then when x = 5 and z = 12:

[tex]y=9(5)(12)=540[/tex]

B. $30,170.36
C. $17.250.00
ОО
D. $26,250.45

Answers

Answer:

p=$15000

R=15%

t=5years

compound amount CI=?

Step-by-step explanation:

we have

CI=p(1+R/100)^t=$15000(1+15/100)^5=$15000×1/15^5=$30170.35

The total amount of $15,000 at 15% compounded annually for 5 years will be $30,170.36 so option (B) is correct.

What is compound interest?

Compound interest is applicable when there will be a change in principle amount after the given time period.

The rate at which compound interest accrues depends on the frequency of compounding.

For instance, if you offer someone $500 at a rate of 10% annually, $500 will be considered your principal sum. After a year, the interest will be $50, making the principle amount $550. Moving forward, the interest will be $550 rather than $500.

Given

Principle amount = $15000

Rate of interest = 15%

The time period T = 5 years.

Compound interest formula

A = P  [tex][ 1 + R/100 ]^{T}[/tex]

A = 15000 [tex][ 1 + 15/100 ]^{5}[/tex]

A = $30,170.36 hence, the total amount after 5 year will be $30,170.36.

Perimeter of a triangle

The perimeter of a triangle is the sum of all the sides of the triangle.

According to the figure shown, the perimeter of the shape is given as:

P = 2x²+1 + 4x+4 + x²+12x
P =3x² + 16x + 5

Factorize

P =3x² + 15x + x+ 5

P = 3x(x + 5) + 1(x+5)

P = (3x + 1)(x+5)

Hence the perimeter of the triangle as a simplified polynomial is (3x + 1)(x+5)
