What is the measure of 3? triangle on right has angles labeled forty-four degrees, sixty-six degrees, and three.?

1 answer:

4 0

[1] First, remember that the sum of the angles in a triangle must add up to 180*.

[2] We are told two of the angles, 44* and 66*, but we are missing the third.

[3] Combining [1] and [2], we know that 44* + 66* + ? = 180*. In other words,
110* + ? = 180*
so,
? = 70*

The missing angle 3 is equal to 70 degrees.

1)The table below represents a linear function f(x) and the equation represents a function g(x):

irga5000 [103]

1)The table below represents a linear function f(x) and the equation represents a function g(x):

x y
-1 -11
0 -1
1 9

g(x) = 5x + 1

Part A: Write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x). (6 points)

slope of the data of the table:

slope = rise / run = Δy / Δx = [ 9 - ( - 1) ] / [1 - 0] = 10/1 = 10

Also Δy / Δx = [-1 - (-11) ] / [ 0 - (-1) ] = 10 / 1 = 10

the slope of the function given in the form f(x) = mx + b is m, so the slope of g(x) = 5x - 1 is 5.

Comparisson: the slope of the function g(x) = 5x - 1 is half the slope of the function f(x) represented by the table.

Part B: Which function has a greater y-intercept? Justify your answer.

The y-intercept is the value of y when x = 0, so it is - 1 for the function represented by the table.

The y-intercept of a function given in the form f(x) = mx + b is b, so the y-intercept of g(x) = 5x - 1 is - 1.

So, both functions have equal y-intercept.

2)The table below shows the values of y for each value of x:

x y
1 0
1 -1
2 1
2 -2

Part A: Does the table represent a relation that is a function? Justify your answer by using the values shown in the table. (4 points)

No, it is not a function, because the relation is ambiguous: the x-coordinate 1 may have two differente values, and the x-coordinate 2 may have two different. So you cannot determine the images of x = 1 and x = 2.

Part B: The function f(x) shown below represents the number of baskets Jess made at different distances, x, in meters, from the hoop:

f(x) = -x + 6

Calculate and interpret the meaning of f(4). (4 points)

f(4) = - 4 + 6 = 2

It means that Jess made 2 baskets at the distant of 4 meters.

Part C: Write an ordered pair to represent the input and output of the function in Part B when Jess is at a distance of p meters from the hoop. (2 points)

input, p output, f(p)

6 -6 + 6 = 0

So the ordered pair is (6,0)

6 0

John has 260 apples. 1/2 of the apples are green and 1/4 of the apples are bad. The rest of the apples are red. How many red app

chubhunter [2.5K]

Answer:

Step-by-step explanation:

1/2 which is half of total is green

1/4 is bad and the remaining apples are red

1/2 of 260 = 130 green apples

1/4 of 260 = 65 bad apples

the remaining is 1/4 which is equal to 65 are red apples
