What is dilation of triangle?Dilation of triangle means each point is stretched outwards or inwards from the center point by multiplying by the scale factor to form a similar triangle.
We have,
Triangle [tex]T V W[/tex] which has points [tex](- 4, 8)[/tex], [tex](0, 4)[/tex], and [tex](4, 4)[/tex] on a coordinate plane.
Scale factor [tex]\frac{3}{4} x, \ \frac{3}{4} y[/tex]
It has to be dilated to create a new triangle [tex]T'V'W'[/tex] .
So,
To create a new triangle [tex]T'V'W'[/tex] we have to multiply the original triangle's coordinate by scale factor, to get new triangle's coordinate .
So, we have to dilate the coordinates by [tex]\frac{3}{4} x, \ \frac{3}{4} y[/tex] ,
[tex]T'=(- 4, 8)=\frac{3}{4} *(-)4, \frac{3}{4} *8= (-3,6)[/tex]
[tex]V'=(0, 4)=\frac{3}{4} *0, \frac{3}{4} *4=(0,1)[/tex]
[tex]W'=(4, 4)=\frac{3}{4} *4,\frac{3}{4} *4=(0,0)[/tex]
So, the coordinates of triangle [tex]T'V'W'[/tex] after dilation are [tex](-3,6), \ (0,1), \ (0,0)[/tex] . Hence we can say that the coordinates of the endpoints of the segment [tex]T'V'[/tex] are [tex](-3,6), \ (0,1).[/tex]

15. Roberto paid $35.75 for dinner at a restaurant, plus an additional $7.15
tip. What percent of the bill did he pay as a tip? Round to the nearest
percent, if necessary.
Answer:
He paid 17% of the bill as a tip.
Step-by-step explanation:
Paid $35.75 for dinner at a restaurant, plus an additional $7.15 tip.
So in all, he paid 35.75 + 7.15 = $42.9
Tip as a percent:
Tip(7.15) multiplied by 100 and divided by the total(42.9). So
7.15*100/42.9 = 16.7%
Rounded to the nearest percent
He paid 17% of the bill as a tip.

Answer:
[tex]h^{l} (s) = \frac{1 }{(\sqrt{s}) (1-\sqrt{s})^{2} }[/tex]
Step-by-step explanation:
Explanation
Given that

Differentiating equation (i) with respective to 'x' ,we get
[tex]h^{l} (s) =\frac{1-\sqrt{s}) \frac{1}{2\sqrt{s} } -(1+\sqrt{s})(\frac{-1}{2\sqrt{s} )} }{(1-\sqrt{s})^{2} }[/tex]

[tex]h^{l} (s) = \frac{\frac{2}{2\sqrt{s} } }{(1-\sqrt{s})^{2} }[/tex]
[tex]h^{l} (s) = \frac{1 }{(\sqrt{s}) (1-\sqrt{s})^{2} }[/tex]

kilometers did they hiked in all?
Asked/ Problem: How many kilometers did
they hiked in all?
Answer:
the number of kilometers hiked in all is [tex]\frac{29}{21}[/tex]
Step-by-step explanation:
The computation of the number of kilometers hiked in all is shown below:
= Erwin + Jericho
[tex]= \frac{5}{7} + \frac{2}{3}\\\\= \frac{15 + 14}{21} \\\\= \frac{29}{21}[/tex]

Answer:
true
Step-by-step explanation:
the line is going down. if it was positive then it would be going from left all to right going up.
Answer:
Yes
Step-by-step explanation:
A slope is "change in y divided by change in x"
If the change in x is +2 then (if you look at the graph) you see that the change in y will be -1.
Since "change in y divided by change in x" is the slope. Change in y is -1 and change in x is +2.
-1 / 2 = -0.5
and there you have it!
The slope is -0.5, which is a negative number. So the slope is negative.

Recall that there are 2π radians in one full rotation and 360 degrees in one full rotation.
Suppose an angle has a measure of 2.1 radians.
This angle (with a measure of 2.1 radians) is what percent of a full rotation?
 %
Use your work in part (i) to determine the measure of the angle in degrees.
 degrees
Answer: (i) This angle is 33.41% of the full rotation.
(ii) 120.38°
Step-by-step explanation:
GIven: Measure of full rotation = 2π radians
Measure of an angle = 2.1 radians.
The percent of this angles of a full rotation = [tex]\dfrac{2.1}{2\pi}\times100\%[/tex]
[tex]=\dfrac{2.1\times7}{2\times22}\times100\% \ \ \ \ [\pi =\dfrac{22}{7}]\\\\=33.41\%[/tex]
i.e. This angle is 33.41% of the full rotation.
In degrees,
[tex]\text{ 2.1 radians}=2.1\times\dfrac{180}{\pi}\\\\=2.1\times\dfrac{180}{3.14}\approx120.38^{\circ}[/tex]
[tex]2.1\text{ radians}[/tex] is [tex]33.4\%[/tex] of a full rotation and is equivalent to [tex]120.2^\circ[/tex]
The relationship between degree and radian measures is
[tex]1\text{ radian}=\dfrac{180}{\pi}^\circ[/tex]
Part 1We want to express [tex]2.1\text{ radians}[/tex] as a percentage of a full rotation.
[tex]\dfrac{2.1}{2\pi}\times100\%=\dfrac{210}{2\pi}\%\\\\\approx33.4\%[/tex]
Part 2How do we determine the measure of an angle (in degrees) given the percentage? Simply multiply the percentage by the complete/full rotation (that is [tex]360^\circ[/tex])
[tex]33.4\%\times360^\circ\\\\=\dfrac{33.4}{100}\times360^\circ\\\\\approx120.2^\circ[/tex]
