The car's speed after the given amout of time is 19.8 m/s²

<h3>How would you define acceleration?</h3>

The rate at which an object's velocity with respect to time changes is referred to as acceleration in mechanics. They are vector quantities, accelerations. The direction of the net force acting on an object determines the direction of its acceleration. A point or object going straight ahead is accelerated when it accelerates or decelerates. Any alteration in an object's velocity could take the form of a change in direction of motion or a speed increase or reduction. The moon orbiting the earth, an apple falling to the ground, and a car stopped at a stop sign are a few instances of acceleration.

Average Acceleration =Change in Velocity/ Time Taken

So Change in Velocity is 10-x m/s

Time taken is 7.25 s

Given accelaration 4.11 m/s²

Putting the values we get,

4.11 = (10-x)/7.25

⇒29.8 = 10-x

⇒x=19.8 m/s²

Circle P is tangent to the x-axis and the y-axis. If the coordinates of the center are (r, r), find the equation of the line con
almond37 [142]

Answer:

y=-x+r

Step-by-step explanation:

we know that

The tangency point on the x-axis is  (r,0)

The tangency point on the y-axis is  (0,r)

Find the slope of the line containing the points of tangency

m=\frac{0-r}{r-0}=-1

Remember that the equation of the line into slope intercept form is equal to

y=mx+b

where

m is the slope

b is the y-coordinate of the y-intercept

In this problem we have

m=-1

b=r

substitute

y=-x+r

For which problem do you need to regroup 1 ten as 10 ones? Fill in the bubble next to the correct answer. Subtract 16 from 38, s
Kaylis [27]

Answer:

subtract 27 from 85

Step-by-step explanation:

85

-27

———

58

7 cannot be subtracted from 5 so borrow a 10 to make it 7 subtracted from 15 and then the 8 tens becomes 7 tens so 7-2=5

58+27=85 to check your work

How do you factor 1/4(-16x+8)?​
Nikitich [7]
We know that we can take 4 out of (-16x + 8) [ we know this because we can divide 16 by 4 ( to get 4 ) and we can divide 8 by 4 ( to get 2 ) ]

we can factor out a 4 then from the parentheses to get 4(-4x + 2), but since we are multiplying by 1/4 we get

1/4(4)(-4x + 2), and since 1/4 * 4 = 1, our final answer is

-4x + 2
