Here is the graph of a function showing the amount of money remaining on a subway fare card as a function of the number of rides taken.

What is the output of the function when the input is 10? ____

What is the input to the function when the output is 5? _____

Answers

Answer:

10 is 14 (10,14) and 5 is 16 (5,16)

Step-by-step explanation:

the output is the same as the x value or the number of rides taken. The y is the amount on the card, or how much money is left of the card. So to solve this question, you want to follow the x-axis (the bottom numbers) til you reach the output you need then match that with the input by looking directly left on the chart. Hopes this helps!

In triangle ABC, AC = 15 cm and AB = 10 cm . The angle at B is a right angle Calculate the length of BC. Give your answer correct to one decimal place.

Answers

Use the Pythagorean Theorem since triangle ABC is a right triangle.

Pythagorean Theorem: a^2+b^2=c^3.

Substitute the 2 side lengths in and find the 3rd side length:

15^2+10^2=c^2.

225+100=c^2 by exponents.

325=c^2 by addition.

18.027=C by Square Root P.O.E.

C=18.027 by Symmetric P.O.E

The 3rd length is 18.027 or Square root of 36.

Answer:

11.1 cm

Step-by-step explanation:

draw the triangle with a base length as 10cm and mark a 15cm with the compass on the mark A and also draw a straight line forming a right angle at B and connect the two lines with another straight line at which the vertex is C. at last measure the line.

Answer:

First answer is correct

Step-by-step explanation:

Answer:

OK.

Now

The points that Make this triangle are

A(-2, 3)

B(-3, 1)

C(-1, 1)

When we Translate 6units right and 2 units Up...

It means

Say we have point (x,y)

we translate 6 units right(Referring to the x coordinate) and 2 units up(referring to y coordinate)

So after translation

Point (x,y) would be (x+6 , y +2)

So Lets apply this to the points given above

A(-2,3) Would be (-2+6 , 3+2) = (4,5)

B(-3,1) would be ( -3+6 , 1+2) = (3,3)

C(-1,1) would be (-1+6 , 1+2 ) = (5, 3)

So We have It

Our Answer

is

(3,3) (5,3) ( 4,5)

Answer:

the answer is B (x and y have a weak, positive correlation)

Give the person above me brainlyest for helping!

Step-by-step explanation:

The coefficient of correlation for the given data of x and y is 0.78.

x and y have a strong, positive correlation

What is Coefficient of Correlation?

A correlation coefficient is a number between -1 and 1 that tells you the strength and direction of a relationship between variables. In other words, it reflects how similar the measurements of two or more variables are across a dataset.

Here, given values of x and y

x   1    2    3   4   5    6

y   3   4    9   7    2    18

xy  3   8   27  28 10  108

x²   1   4    9    16   25   36

y²   9  16  81  49  4  324

∑x = 21,  ∑y = 43,  ∑xy = 194, ∑x² = 91, ∑y² = 483, n = 6

Now, Correlation between x and y

r = (n∑xy - ∑x.∑y)/ √[{n∑x²- (∑x)²}{n∑y² - (∑y)²}]

r = ( 6 X 194 - 21 X 43 ) / √[ {6 X 91 - (21)²}{ 6 X 483 - (43)²}]

r = ( 1164 - 903) / √( 546 - 441)(2898 - 1849)

r = 261 / √ 105 X 1049

r = 261 / √110145

r = 261 / 331.88

r = 0.78

Thus, The coefficient of correlation for the given data of x and y is 0.78.

x and y have a strong, positive correlation
