A,b&c from a triangle where < bac= 90° Ab= 13.9 mm and ca= 8.8mm find the length of bc ?

Answers

Answer:

BC = 1 6.45

Step-by-step explanation:

The way it is written, BC is the  hypotenuse

BC^2 = AB^2 + CA^2             Substitute the numbers for AB and CA

BC^2 = 13.9^2 + 8.8^2           Perform the squares

BC^2 = 193.21 + 77.44           Add the right side

BC^2 = 270.65                      Take the square root of both sides

BC = 16.45

Compare positive and negative slope for linear relationships. How are they the same? How are they different?

Answers

Answer:

Please check explanations

Step-by-step explanation:

Slopes are generally the ratio of rise(vertical difference) to fall (horizontal difference) for set of points lying on a straight line

Positive slopes show a positive relationship between the two things we are considering while a negative one shows otherwise

They are the same in the sense that they actually represent a constant change between the coordinates of the points in the relationship we are considering.

They are different in the sense that while one represents a positive change, whereby both axes move in the same direction ( rise at same rate, fall at same rate) , the second represent a relationship in which they move in opposite directions. While one falls, the other rises and while the other rises, the second one falls which indicates an opposing movement type between the two

I think it's the first last one because proportional means it increases by the same each time so the last one fits in that category

Answer:

Number 1 is proportional, 2 is non proportional, 3 non proportional, 4 non proportional.

Step-by-step explanation:

You divide . 4÷1=4 , 8÷2=4, 12÷3=4, the unit rate MUST be the same !!!! And if there's 0 0, that doesn't count so like if your other 2 have the same unit rate it would still be proportional.

Hal is asked to write an exponential function to represent the value of a $10,000 investment decreasing at 2% annually. What multiplicative rate of change should Hal use in his function?

0.02
0.98
1.02
1.98

Answers

Answer

The multiplicative rate of change that should be in Hal’s function = 49/50=0.98

                                                                                                                  =9.8×10⁻¹

Explanation

The investment of $10,000 decreases by 2% every year. So the following year is usually (100 - 2)=98% of the previous year. This is a geometric progression.

In this case the first term = 10000

The second term = 98% × 10000 = 9800.

The common ratio = 9800/10000=49/50

The multiplicative rate of change that should be in Hal’s function = 49/50=0.98.

The equation of the exponential rate would be;

10,000ₓ0.98ⁿ.

where n is the number years.

Hope his helps! ;)

A chair normally priced at $75, is marked down to $41.25. What is the percentage decreased for the chair?

Answers

Answer:

The answer is B. I think.

Step-by-step explanation:

$75 divided by 10 is 7.5

7.5 = 10%

$41.25 divided by 7.5 or 10% = 5.5

5.5 x 10 = 55%

Sorry if this is not helpful.

The percentage decrease of the chair will be 55%.

What is the percentage?

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that the chair normally priced at $75, is marked down to $41.25. The percentage decrease will be calculated below,

Percentage decrease = [ Final price / Normal price ] x 100

Percentage decrease = ( 41.25 / 75 ) x 100

Percentage decrease = 0.55 x 100

Percentage decrease = 55%

PLS HELP LOL!!! Isabella and Alice are standing some distance apart on the same side of a building 50 meters tall. From where Isabella stands, the angle of elevation of the top of the building is 30. From where Alice stands, the angle is 60. What is the distance between Isabella and Alice to the nearest tenth of a meter?

Answers

Answer:

57.7 m

Step-by-step explanation:

Since the distance between Isabella, the building and the angle form a right angled triangle with the height of the building = h = 50 m as the opposite side and x = distance between Isabella and the building = adjacent side and Ф = angle of elevation of the top of the building from Isabella = 30°.

So, from trigonometric ratios,

tanФ = h/x

and x = h/tanФ

= 50 m/tan30°

= 50/0.5774

= 86.6 m

Also, the distance between Alice, the building and the angle form a right angled triangle with the height of the building = h = 50 m as the opposite side and x' = distance between Alice and the building = adjacent side and Ф' = angle of elevation of the top of the building from Alice = 60°.

So, from trigonometric ratios,

tanФ' = h/x'

and x' = h/tanФ'

= 50 m/tan60°

= 50/1.7321

= 28.87 m

So, the distance between Isabella and Alice, x" = x - x'

= 86.6 m - 28.87 m

= 57.73 m

≅ 57.7 m
