A car traveling at 45 ft/sec decelerates at a constant 7 feet per second squared. How many feet does the car travel before coming to a complete stop

Answers

Answer 1

Answer:

s = 144.64 feet

Step-by-step explanation:

Given that,

The initial speed of a car, u = 45 ft/s

Deacceleration of the car, a = -7 m/s²

We need to find the distance covered by the car travel before coming to a complete stop. let it is d.

Final velocity, v = 0

Using the third equation of motion as follows :

[tex]v^2-u^2=2as\\\\s=\dfrac{v^2-u^2}{2a}\\\\s=\dfrac{0^2-45^2}{2\times (-7)}\\\\s=144.64\ \text{feet}[/tex]

So, it will cover a distance of 144.64 feet.

How many boxes with a Length/Width/Height of 1/4, 1/4, and another 1/4 would fit into a box with a Length/Width/Height of 3 1/4, 3, and 3 3/4?

Answers

9514 1404 393

Answer:

  2340 small boxes

Step-by-step explanation:

Each unit of measure used for the large box will contain 4 of the smaller boxes. So, in terms of small boxes, the dimensions of the larger box are ...

  (3 1/4)/(1/4) = (13/4)/(1/4) = 13 . . . length

  3/(1/4) = (12/4)/(1/4) = 12 . . . . . . . width

  (3 3/4)/(1/4) = (15/4)/(1/4) = 15 . . . height

Then the number of small boxes that would fit is ...

  length × width × height = 13×12×15 = 2340

2340 cubes of size 1/4 will fit into the larger box.

Which reason justifies statement 2?

A) Vertical angles are congruent

B) Corresponding angles are congruent

C) Alternate interior angles are congruent

D) Alternate exterior angles are congruent

Answers

Answer:

C. Alternate interior angles are congruent

Step-by-step explanation:

<Y and <4 are two alternate angles within the two parallel lines cut across by the transversal, hence, they are called alternate interior angles.

Alternate interior angles are always congruent to each other. Therefore, the reason that justifies statement two: "<Y ≅ <4", is "Alternate interior angles are congruent".

1. Find the distance from point P to QS
SHOW ALL OF YOUR WORK

S(0,8)
R(-3,5)
Q(-5,3)
P(1, 1)

Answers

Answer:

5.7 units

Step-by-step explanation:

The distance from point P to QS is the distance from point P (1, 1) to the point of interception R(-3, 5).

Use distance formula to calculate distance between P and R:

[tex] PR = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

Let,

[tex] P (1, 1) = (x_1, y_1) [/tex]

[tex] R(-3, 5) = (x_2, y_2) [/tex]

Plug in the values into the formula.

[tex] PR = \sqrt{(-3 - 1)^2 + (5 - 1)^2} [/tex]

[tex] PR = \sqrt{(-4)^2 + (4)^2} [/tex]

[tex] PR = \sqrt{16 + 16} [/tex]

[tex] PR = \sqrt{32} [/tex]

[tex] PR = 5.7 units [/tex] (to nearest tenth)

The point-slope form of the equation of a line that passes through points (8, 4) and (0, 2) is y - 4 = (x – 8). What
is the slope-intercept form of the equation for this line?
O y = 1 x - 12
O y = -x-4
O y=+*+2
O y=x+6

Answers

Answer: y = x/4 + 2

Y equals one fourth x plus two.

Step-by-step explanation:

There seems to be a typo on answer choice c.

Slope intercept form is y= mx + b

m is the slope. b is the y-intercept.

The y-intercept is given here in the coordinate (0,2) It is +2

Slope is rise/run.

Rise: Difference in given y-values is 4-2 = 2.

Run: Difference in x-values is 8-0=8.

So the slope is 2/8 = 1/4

The equation is y = 1/4 x + 2
