Answer:
-2/3
Step-by-step explanation
Use the two points on the graph to calculate the slope. (2, -1) and (-4, 3)
The formula is (y2 - y1)/(x2 - x1) so (3 - (-1))/(-4 - 2) = 4/-6 = -2/3

I don't understand how to prove it's tangent. Help quickly please.
Step-by-step explanation:
by using pythagorean theorem:
XW²+XY²=
(2×6.4)² + 9.6² =
12.8²+9.6²=
163.84 + 92.16= 256
WY²= 16²= 256
so, XW²+XY²=WY²
=> the WXY is a right triangle, and X is a right angle.
so XY is perpendicular to XW as the diameter of circle Z.
and XY is tangent to circle Z
Two angles are supplementary. One angle has a measure of 51 degrees. What is the measure of the second angle?
Answer:
129°
Step-by-step explanation:
Sum of supplementary angles = 180°
One angle = 51°
Other angles = 180° - 51°
= 129°

Find the area of the shaded region.
800
5 cm
A=[?] cm2
Enter a decimal rounded to the nearest tenth.
Enter
If the radius of the circle is 5 cm and central angle is 80° then the area of the shaded region is 61.06.
Given that the radius of the circle is 5 cm and central angle is 80°.
We are required to find the area of the shaded region.
The area of the shaded region is basically the difference between the area of the whole circle and the area of the arc which is not shaded.
Area of circle=π[tex]r^{2}[/tex]
=3.14*25
=78.5 [tex]cm^{2}[/tex]
Area of the arc =([tex]r^{2}[/tex]Θ)/2
=(25*80π)/2*180
=(25*80*3.14)/360
=6280/360
=17.44
Area of the shaded region=78.5-17.444
=61.056
After rounding off to the nearest tenth it will be as under:
=61.06
Hence if the radius of the circle is 5 cm and central angle is 80° then the area of the shaded region is 61.06.

Which inequality is represented by the graph
Triangle ABC with vertices A(4, −6), B(2, −8), and C(−10, 4) is dilated by a scale factor of 2 to obtain triangle A′B′C′. Which statement best describes triangle A′B′C′? (5 points) Group of answer choices
It is congruent to triangle ABC and has coordinates A′(8, −12), B′(4, −16), and C′(−20, 8).
It is congruent to triangle ABC and has coordinates A′(2, −3), B′(1, −4), and C′(−5, 2).
It is similar to triangle ABC and has coordinates A′(8, −12), B′(4, −16), and C′(−20, 8).
It is similar to triangle ABC and has coordinates A′(2, −3), B′(1, −4), and C′(−5, 2).
Answer:
I believe it is A I may be wrong
It is similar to Triangle ABC and has coordinate A'(8, -12), B'(4, -16), and C' (-20, 8).
Since its getting dilated by 2 it will be getting bigger

find the missing sides of the triangle
Answer:
D
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin30° = [tex]\frac{1}{2}[/tex] , then
sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{12}{f}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
f = 24
----------------------------------------------------------------
Using the cosine ratio and the exact value
cos30° = [tex]\frac{\sqrt{3} }{2}[/tex] , then
cos30° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{e}{f}[/tex] = [tex]\frac{e}{24}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )
2e = 24[tex]\sqrt{3}[/tex] ( divide both sides by 2 )
e = 12[tex]\sqrt{3}[/tex]
Answer:
F=24 and e=12[tex]\sqrt{3}[/tex]

Jenny has 3 times as many new toys as she has favorite toys. The total number of toys is 60. How many favorite toys might Jenny have?
Answer:Jenny has 15 favorite toys
Step-by-step explanation:
Jenny has 3 times as many new toys as she has favorite toys means that the ratio of new toys to favorite toys can be written as 3:1
Total Ratio=3+1=4
Since the total number of toys is given as 60
Amount of Favorite toys = ratio of favorite toys / Total ratio x Total number of toys
Amount of Favorite toys = 1/4 x 60=15
Therefore Jenny has 15 favorite toys.
