Answer 1

Answer:

30²-18²=x²

x²=576

x= 24 inches

Answer 2

Answer: a²+b²=c²
30²-18²=b²
576=b²
√576=√b²
b=24
so your answer will be C 24 inches

Brad needs (30.1 + 37.5 + 14.8 + 10.01 + 15.2) = 107.61 cm of wood.

How many lengths does he need in order to have 107.61 cm of wood ?

(107.61 cm) / (35 cm/length) = 3.075 lengths

3 lengths is not quite enough. But it's only sold in whole lengths of 35 cm.
So in order to cover that last little smidgen, he'll need to buy 4 lengths.

another way is: x/$5 =125%/100% and you get 6.25 still.

The ratio of the slopevalues for the given and image triangles are 5/3 and 2.5 respectively.

How to determine the ratio of the slopes from the graph

Using the information on the graph given ;

For the given triangle ;

(2, 3) ; (0, -2)

Rise = change in y

Rise = (-2 - 3) = -5

Run = changein x

Run = 0 - 3 = -3

The ratio;

-5/-3 = 5/3

For the image triangle ;

(4, 8) ; (0, -2)

Rise = change in y

Rise = (-2 - 8) = -10

Run = change in x

Run = 0 - 4 = -4

The ratio ;

-10/-4 = 2.5

Answer:

1) 5/2 or 2.5

2) 5/2 or 2.5

Step-by-step explanation:

1) 5/2 = 2.5

2) 10/4 = 5/2 = 2.5

Because the hypotenuse of both are the segments of the same line and straight lines have the same gradient for all segments

Look at this graph:
Is this relation a function?
yes
no

Answers

Answer: This does not represent a function

Step-by-step explanation: To tell if this relation is a function, we can use the vertical line test. In other words, if we can draw a vertical line that passes through more than one point on the graph, then the relation is not a function. In this situation, it's possible to have a vertical line that passes through more than one point so it's not a function.

Image provided.

This does not represent a function. You can use the vertical line test. If it doesn't go through more than one x value then it is a function.

What are the zeroes of f(x) = x2 − 6x + 8? (1 point) x = −4, 2 x = −4, −2 x = 4, 2 x = 4, −2

Answers

Answer:

x = 4 , 2

Step-by-step explanation:

x² - 6x + 8=0

(x -2)(x + 4)=0

x= 4,2

Therefore the zeros of f(x) are 4 and 2.

Hope this helps.
