Answer:

looking at this picture i see that the x value is -30 and the y value is 30

and looking at this it looks like the slope is 30°.

Step-by-step explanation:

not sure if this is right because i have a blank memory about things i learned in pre alg.

but if i'm wrong forgive me.

and if i'm right good luck on whatever you are doing.

The volume of the second prism is 576 cubic centimeters. Since both prisms have the same height, I solved for the height using the data given with the first prism (I got 6 centimeters for the height). And then I calculated for the volume of the second prism.

A car traveled 360 miles in 4 hours. If its speed were to be 15 mph slower, how long would it take to travel the same distance?

docker41 [41]

Answer:

4.8 hours

Step-by-step explanation:

First, divide the distance by time to get velocity.

S = D/T

S = 360/4

S = 90 mph

Then, subtract 15 from 90 to get the new speed.

90 - 15 = 75

Lastly divide the distance by the new speed to get time.

T = D/S

T = 360/75

T = 4.8

Therefore, it would take the car 4.8 hours to travel 360 miles at 75 miles per hour.

3. What three numbers are the Pythagorean triple generated by using 4 for x and 1 for y. Remember to use the formulas:

Doss [256]

Given:

Consider the three number are given by:

$a=x^2-y^2$

$b=2xy$

$c=x^2+y^2$

To find:

The three numbers are the Pythagorean triple generated by using 4 for x and 1 for y.

Solution:

We have,

$a=x^2-y^2$

$b=2xy$

$c=x^2+y^2$

Substituting 4 for x and 1 for y, we get

$a=4^2-1^2$

$a=16-1$

$a=15$

Similarly,

$b=2(4)(1)$

$b=8$

And,

$c=4^2+1^2$

$c=16+1$

$c=17$

The three three numbers are the Pythagorean triple are 8,15 and 17.

Therefore, the correct option is C.

number 4 I have absolutely no idea how to do. I generally understand finding distance on the coordinate plane but this has reall

Over [174]

For Part A, in creating the square, you did it correctly.

Now for Part B, you can create a right triangle by adding a point at -4, -3, and we'll call it, say, T.

Then you can use the Pythagorean's Theorem to find the length of one side of the square.

The Pythagorean's Theorem is $a^{2} + b^{2} = c^{2}$

A would be the distance between P and T, and B would be the distance between Q and T. So then, a would be 7, and B would be 2.

To fill it in, it would be $7^{2} + 2^{2} = c^{2}$

or 49 + 4 = $c^{2}$

or 53 = $c^{2}$

or $\sqrt{53}$ = x

Which is equal to about 7.28

Now multiply that by 4 to get the perimeter, or 29.12

So the perimeter would be about 29.12
