Answer:

A and B

Step-by-step explanation:

Speed is the change in distance divided by the change in time. That is, it is the slope of the distance vs. time curve. A steeper slope corresponds to a greater speed.

Between A and B, the slope is (30-0)/(1-0) meters/time-unit = 30 m/u.

Between B and C, the slope is (30-10)/(4-1) = 20/3 = 6 2/3 m/u.

Between C and D, the slope is 0.

Between D and F, the slope is (50-10)/(10-6) = 40/4 = 10 m/u.

The greatest slope is between A and B.

The object has the greatest speed between points A and B.

Find the distance between two points ( -1,1) and (2,-4)

sladkih [1.3K]

Answer:

The distance between two points ( -1,1) and (2,-4) is:

$d=\sqrt{34}$ or d = 5.8 units.

Step-by-step explanation:

Given the points

(-1, 1)

(2, -4)

Finding the distance between (-1, 1) and (2, -4) using the formula

$d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}$

substitute (x₁, y₁) = (-1, 1) and (x₂, y₂) = (2, -4)

$=\sqrt{\left(2-\left(-1\right)\right)^2+\left(-4-1\right)^2}$

$=\sqrt{\left(2+1\right)^2+\left(-4-1\right)^2}$

$=\sqrt{3^2+5^2}$

$=\sqrt{9+25}$

$=\sqrt{34}$ units

$d = 5.8$ units

Therefore, the distance between two points ( -1,1) and (2,-4) is:

$d=\sqrt{34}$ or d = 5.8 units.

A total of 24 out of 40 sixth graders buy hot lunch each day. What percent of these students do not buy hot lunch each day?

Goshia [24]

60% of student don't buy a hot lunch.
The simple way of doing it is by taking both numbers and dividing them. 24 divided by 40= 0.6 Since percents are part of a whole, we need to multiply by 100 0.6 times 100 equals 60.
Easy and accurate.
