Answer 1

Answer:

A= 2

B= -1

Step-by-step explanation:

Do rise over run but make sure B is negative as it is going downwards

Answer 2

Answer:

A= 2 B= 9/10 (0.9)

Step-by-step explanation:

to find the gradients, we need to use the formula:

rise / run ---> which is basically counting the "boxes" in both of the x and y axis and divide them together (rise=y, run=x)

like that

A:

x axis=5    y=10 ---> then we use the formula (rise/run) 10/5= 2

B

x axis=10    y=9 ---> then we use the formula (rise/run) 9/10= 0.9

but since B is going downhill, it'll be -0.9

Jamar has a large rectangular box that is 6ft x 8ft x 7ft. Will this box fit a pipe that is 12 ft. Long? Determine the length of the longest straight object that can fit in Jamar's box and show how you know whether the pipe will fit or not.

Answers

Answer:

9.21ft

Step-by-step explanation:

Given data

L= 6ft

W= 8ft

H= 7ft

Let us find the diagonal of the side, this represents the longest size of pipe the box can take

z^2= L^2+ H^2

z^2= 6^2+ 7^2

z^2= 36+49

z^2= 85

z= √85

z= 9.21ft

Hence the 12ft cannot fit into the box

the length of pip that can fit is 9.21ft

The velocity of a car increases from 4 m/s at 2 sec. To 32 m/s at 9 sec. What is the car’s average acceleration?

Answers

Answer:

[tex]a=4\ m/s^2[/tex]

Step-by-step explanation:

Given that,

The velocity of a car increases from 4 m/s at 2 sec to 32 m/s at 9 sec.

We need to find the car's average acceleration. It can be given by the change in velocity divided by the change in time. So,

[tex]a=\dfrac{v-u}{t_2-t_1}\\\\a=\dfrac{32-4}{9-2}\\\\a=4\ m/s^2[/tex]

So, the car's average acceleration is equal to [tex]4\ m/s^2[/tex].

what are the x and y intercepts for this equation y=−1/4x+2?
(_,_)

Answers

Answer:

(8, 0) is the x-intercept

(0, 2) is the y-intercept

Step-by-step explanation:

The y-intercept = 2 since the equation is in slope-intercept form.

The x-intercept occurs when y = 0

So,   0 = -1/4x + 2

        0 = -x + 8

         x = 8

(8, 0) is the x-intercept

(0, 2) is the y-intercept

I was wondering how can I find the length of a side from the angles given​

Answers

sorry if this is wrong but you could use a ruler or protractor

Answer:

The Pythagorean Theorem, a2+b2=c2, a 2 + b 2 = c 2 , is used to find the length of any side of a right triangle.

In a right triangle, one of the angles has a value of 90 degrees.

The longest side of a right triangle is called the hypotenuse, and it is the side that is opposite the 90 degree angle.
