A certain natural number is not divisible by 7. Can it be divisible by 14?

Delicious77 [7]

No because 14 is a multiple of 7 so any number that can be divided by 14 can be divided by 7. (2x7=14)

Rico wants to find the distance between the points (-2,-3) and (2,-5) his work is shown.|-3| + |-5| = 3+5 = 8the distance is 8 u

tino4ka555 [31]

Answer:

Riko is wrong

Step-by-step explanation:

To find the distance of two point, we use the following formula:

A (x1, y1)

B (x1, y2)

AB = $\sqrt{(x2-x1)^{2} + (y2-y1)^{2} }$

In this situation, we have:

A (-2,-3)

B (2,-5)

So the distance is: $\sqrt{(2 - (-2))^{2} + (-5 - (-3))^{2} }$ = $\sqrt{4^{2} + 8^{2} }$ = $\sqrt{80} = 4\sqrt{5}$

Hope it will find you well.

write an equation for the line that is perpendicular to the given line and passes through the given point y-3=8/3(x+2);(-2,3)

Stolb23 [73]

Answer:

$y-3=-\frac{3}{8} (x+2)$

Step-by-step explanation:

We can write the equation of a line in 3 different forms including slope intercept, point-slope, and standard depending on the information we have. We have a point (8,1) and a slope from the equation. We will chose point-slope since we have a point and slope.

Point slope: $y-y_1=m(x-x_1)$

$m\neq \frac{8}{3}$ in our new equation because it is perpendicular to it. This means we will need to change it into its negative reciprocal which is $m=-\frac{3}{8}$ .

We will substitute $m=-\frac{3}{8}$ and $x_1=-2\\y_1=3$ .

$y-3=-\frac{3}{8} (x-(-2))$

$y-3=-\frac{3}{8} (x+2)$

This is the equation of the line perpendicular to the equation given that crosses through (-2,3).

A computer can sort x objects in t seconds, as modeled by the function below: t=0.007x^2+0.003x. How long, in seconds, will it t

AlekseyPX

X objects in t seconds.....how long to sort 15 objects....so x = 15

t = 0.007(15^2) + 0.003(15)
t = 0.007(225) + 0.045
t = 1.575 + 0.045
t = 1.62 seconds <===
