Cos3A= Cos (90-2A)

3A= 90-2A

5A= 90

A= 18

from (i)

Cos(3×18) = Sin (2×18)

Cos54= Sin36

0.5877= 0.5877 proved .

Step-by-step explanation:

3 out of 10 is smaller than 3 out of 5

Answer: 3/10 < 3/5

Step-by-step explanation:

Choose one of the fractions to convert to a common denominator, we'll use 3/5 in this case

3/5 to the common denominator of 10, to get to 10 you need to multiply both the numerator and denominator by 2

2 * (3/5) * 2 = 6/10

6/10 is greater than 3/10, which means 3/10 is less than 3/5

Therefore, 3/10 < 3/5

Step-by-step explanation:

it is 5 pounds your welcome

The bigger measurement is 5 lbs.

Measurement is the method of comparing the properties of a quantity or object using a standard quantity.

Measurement is essential to determine the quantity of any object.

Given two measurements.

75 ounces and 5 lbs.

We have the conversion formula,

1 lbs = 16 ounces

5 lbs = 5 × 16 = 80 ounces

80 ounces is greater than 75 ounces

5 lbs is greater than 75 ounces.

Hence the measurement which is bigger is 5 lbs.

1. Distribute:  6x-12 - 6x+12

2. Combine like terms:  0

Answer:

0

Step-by-step explanation:

First you want to do distributive properties, so multiply 2 and -4 by 3. leaving you with 6x-12-6x+12. then we have to combine all the like terms. so you can either add 6x to the negative 6x or take away 6x from the positive 6x. Same with the 12's. so once you've combined all the like terms you should be left with 0. Thus, your answer would be 0.

Answer:

Step-by-step explanation:

Out of the available options on the spinner, only 1 and 5 are factors of 25.

=> Outcomes = 2

=> Total outcomes = 5

P (factor of 25) = 2/5

Hope it helps.

Answer:

[tex]\frac{2}{5}[/tex]

Step-by-step explanation:

Probability is calculated as

P = [tex]\frac{desiredoutcome}{possibleoutcomes}[/tex]

desired outcome is factor of 25

factors of 25 are 1 and 5 , that is 2

possible outcomes are 1, 2, 3, 4, 5 , that is 5

P( factor of 25 ) = [tex]\frac{2}{5}[/tex]

Answer:

see attached diagram

Step-by-step explanation:

If the kite starts on the ground, then the beginning point of your graph will be (0, 0) since when time = 0, height of the kite = 0.

If it ascends slowly into the sky, then as time passes, its height increases.

So you will draw a straight line with a positive gradient from (0, 0).

As it ascends slowly, the gradient needs to be small.

If it flies at the same altitude (height) for about 10 minutes, this means that the height stays the same, so you will draw a horizontal line to show this.

The if it quickly drops to the ground, draw a line with a large, negative gradient to a point on the x-axis (as height = 0)

The graph shifts 7 units right and 2 units down

Step-by-step explanation:

When p<0 it shifts to the left hence it has shifted 7 units to the right.

When q<0 it shifts down so hence it has shifted 2 units down

Step-by-step explanation:

Collision is the type of insurance can be waived (refused) if a driver feels that his/her car is not worth insuring.

Insurance is a means of protection from financial loss in which, in exchange for a fee, a party agrees to compensate another party in the event of a certain loss, damage, or injury.

Collision insurance covers the cost of repairing or replacing a driver's car if it is damaged in an accident.

It is typically optional and not required by law.

If a driver feels that the value of their car is low and that the cost of collision insurance is not worth the potential benefit, they may choose to waive (refuse) this type of coverage.

Comprehensive insurance covers damage to a driver's car from causes other than an accident, such as theft, vandalism, or natural disasters. Liability insurance covers damages and injuries that a driver causes to others in an accident.

Uninsured motorist insurance covers damages and injuries to a driver if they are hit by an uninsured or underinsured driver.

Hence, collision is the type of insurance can be waived (refused) if a driver feels that his/her car is not worth insuring.

Answer:

[tex]y= -\frac{1}{2}x+5[/tex]

Step-by-step explanation:

When lines are perpendicular to each other, the slopes are negative reciprocals.

The slope of line y=2x+11 is 2. The negative reciprocal of that is -1/2.

Next, plug in the x and y values so we can get b (y intercept).

[tex]3= -\frac{1}{2}(4)+b\\ 3=-2+b\\5=b[/tex]

Our equation is [tex]y= -\frac{1}{2}x +5[/tex]

Answer:

  Total Area = 110 m²

Step-by-step explanation:

To find the area of this composite shape, extend the top horizontal line to the right. That divides the figure into a right triangle (above the extended line) and a rectangle (below the extended line).

Name: triangle

Formula: A = 1/2bh

Values: b = 15 m -5 m = 10 m; h = 4 m

Area = 1/2(10 m)(4 m) = 20 m²

__

Name: rectangle

Formula: A = bh

Values: b = 15 m; h = 6 m

Area = (15 m)(6 m) = 90 m²

__

Total area = Shape 1 area + Shape 2 area

Total area = (20 m²) +(90 m²) = 110 m²

Step-by-step explanation:

A line can be translated over to form a line. Since the line has the same slope, the only thing different is y intercept. Since a Translation is a rigid transformation, they perseve distance. So this will be true for all lines.

Key Concept: The distance between two parallel lines and is the difference in y intercepts.

10. The y intercept is 7 and -2

So the distance is

[tex]7 - ( - 2) = 9[/tex]

or

[tex] - 2 - 7 = - 9[/tex]

Rember Distance is a scalar, so it is positve.

So we take absolute value of both answer

[tex] |9| = 9[/tex]

[tex] | - 9| = 9[/tex]

So the answer for 10 is 9.

11. The distance is 3 because |4-1|=3 or |1-4|=3 so the distance is 3.

12. The distance is 2

13.The distance is 8.
