Move the horizontal and vertical sliders some more to stretch the image of the triangle. As you move thesliders, observe what happens to the interior angles of each triangle. Based on your observations, can you say
that stretches preserve angle measurements?

Answers

Answer 1
Answer:

Answer:

No, stretches do not preserve angle measurements. A stretch in either the horizontal or the vertical direction changes the interior angles.

The distance between -6 and 15 on a number line is 9?

Answers

The distance between -6 and 15 on a number line is 21.

What is number line?

A straight line with numbers placed at equal intervals or segments along its length. Number line is a straight line with a "zero" point in the middle, with positive and negative numbers listed on either side of zero and going on indefinitely.

Given:

The distance between -6 and 15 on a number line is 9 is true or false.

We have to find the the distance between -6 and 15 on a number line.

According to given question we have

15 - (- 6)

= 15 + 6

= 21

The distance between -6 and 15 on a number line is 9 is false.

Therefore, the  distance between -6 and 15 on a number line is 21.

Answer:

21 units. your answer is false.

Step-by-step explanation:

-6 to 0 = 6

0 to 15 = 15

you are counting Units not physical numbers. don't forget that!

correct distance is 21

A world class sprinter ran 200 m in 22.75s. What was her average speed?m/s
Enter a number.

Answers

Answer:

8.8

Step-by-step explanation:

speed=distance/time

speed- ?

distance- 200m

time- 22.75s

?=200/22.75

?= 8.791...

round it so that it becomes 8.8

4(2x + 4) = 10x + 13 - 2x + 3.
Solve for x

Answers

Answer:

x is any Real number

Step-by-step explanation:

We first apply distributive property on the left to get rid of the grouping symbol, and then combining the like terms (linear terms on one side and numerical terms on the other side of the equation):

8x+16=10x+13-2x+3\n16-13-3=10x-2x-8x\n0=0

This equation results on a TRUE equality Zero = Zero, which means that any value we use for "x" in the original expression will always render an equality.

Therefore x is any Real number.

Dy/dx=2xy/x²+y² solve​

Answers

Answer:

y=(-1)/(2) \sqrt[]{4x^2+4c_(1)^2} -c_(1)\ or \ (1)/(2) \sqrt[]{4x^2+4c_(1)^2} -c_(1)

Step-by-step explanation:

As it is first order nonlinear ordinary differential equation

Let y(x) = x v(x)

2xy/(x²+y²)=2v/(v^2+1)

dy=xdv+vdx

dy/dx=d(dv/dx)+v

x(dv/dx)+v=(2v)/(v^2+1)

dv/dx=[(2v)/(v^2+1)-v]/x

(dv)/(dx)=(-(v^2-1)v)/(x(v^2+1))

(v^2+1)/((v^2-1)v)dv=(-1)/(x)dx

∫(v^2+1)/((v^2-1)v)dv = ∫(-1)/(x)dx

u=v^2

du=2vdv

Left hand side:

∫(v^2+1)/(v(v^2-1))dv

=∫(u+1)/(2u(u-1))du

=(1)/(2)∫((2)/(u-1) -(1)/(u) )du

=ln(u-1)-(ln(u))/(2) +c

=ln(v^2-1)-(ln(v^2))/(2)+c

Right hand side:

=-ln(x)

Solve for v:

v=-\frac{-c_(1)+\sqrt{c_(2)+4x^2 } }{2x} \ or \ \frac{-c_(1)+\sqrt{c_(2)+4x^2 } }{2x}\n

y=(-1)/(2) \sqrt[]{4x^2+4c_(1)^2} -c_(1)\ or \ (1)/(2) \sqrt[]{4x^2+4c_(1)^2} -c_(1)
