BRAINLIEST!! If the area of ABC is D, give the expressions that complete the equation for the measure of angle C
The measure of the m and n from the triangle are 2D and ab respectively
How to calculate the area of a triangle?A triangle is a 2-dimensional shape with 3 sides and angles. The area of the given angle is expressed as:
Area = 1/2 ab sin<C
Since the area is D, hence;
D = 1/2absinC
2D = absin C
sinC = 2D/ab
C = arcsin(2D/ab)
Compare
m = 2D
n = ab
Hence the measure of the m and n from the triangle are 2D and ab respectively

Line g is dilated by a scale factor of 2 from the origin to create line g'. Where are points E' and F' located after dilation, and how are lines g and g' related?
coordinate plane with point E at negative 4 comma 0 and point F at 0 comma 2, line g intersects points E and F
The locations of E' and F' are E' (−8, 0) and F' (0, 4), and lines g and g' are parallel.
The locations of E' and F' are E' (−4, 0) and F' (0, 2), and lines g and g' are the same line.
The locations of E' and F' are E' (−2, 0) and F' (0, 1), and lines g and g' intersect at point F.
The locations of E' and F' are E' (−1, 0) and F' (0, 0), and lines g and g' are not related.
Answer:
The points where E' and F' are located after dilation and how the lines g and g' are related are;
The locations E' and F' are E'(-8, 0) and F'(0, 4), and lines g and g' are parallel
Please see attached plot of lines g and g' created with MS Excel
Step-by-step explanation:
When an object is dilated by a scale factor, the length of the sides of the image formed is given as follows;
The length of the image = The length of the figure × The scale factor
The given parameters are;
The center of dilation = (0, 0) Dilated from the origin
The coordinates of the endpoint of the line 'g' = E(-4, 0), F(0, 2)
Therefore, we have;
The 'x', and 'y' coordinates of the point E' on the image from the center of dilation (0, 0) = (-4 × 2, 0 × 2) = (-8, 0)
The 'x', and 'y' coordinates of the point F' on the image from the center of dilation (0, 0) = (0 × 2, 2 × 2) = (0, 4)
Therefore, the coordinates of the point E' and F' on line g' = E'(-8, 0) and F'(0, 4)
Given that the proportion of the distances of E and E' to center of dilation (to the origin) and F and F' center of dilation are equal by the triangle proportionality theorem, EF is parallel to E'F' and the lines g and g' are said to be parallel
Therefore;
The coordinate of point E' = (-8, 0) and The coordinate of point F' = (0, 4)
Ling g is parallel to line g'
Answer:
The locations of E' and F' are E' (−8, 0) and F' (0, 4), and lines g and g' are parallel.

Answer:
The values of x and y are 23.83 and 31.1.
Step-by-step explanation:
Given that,
Perpendicular = 20 units
Angle, [tex]\theta=40^{\circ}[/tex]
We need to find the values of x and y.
Using trigonometry,
[tex]\tan(40)=\dfrac{20}{x}\\\\x=\dfrac{20}{\tan(40)}\\\\x=23.83[/tex]
To find y use Pythagoras theorem,
[tex]y^2=23.83^2+20^2\\\\y=31.1[/tex]
So, the values of x and y are 23.83 and 31.1.

After spending some time looking for his pump, Marlon pumps up an uninflated balloon, pumping air into it at a constant rate. He ties the balloon with a string to prevent the air from escaping.
Which graph could represent this scenario?
Answer:
Graph D
Step-by-step explanation:
Initially, Marlon was looking for his pump. Thus, no air was pumped into the balloon until he got the pump. On getting the pump, he inflated the balloon with air at a constant rate, after which he tied it with a string to prevent the air from escaping.
The analysis is that, at the time he decided to inflate the balloon till he got a pump, the volume of air in the balloon is zero with respect to time. Pumping air at a steady rate into the balloon increases the volume of air flowing into it gradually and steadily.
When the volume got to a definite amount, he stopped pumping air and tied with a string. Thus, the volume of air in the balloon remains constant.

Based on the observed frequencies, which percent represents a reasonable probability of rolling a number less than 3?
14%
o
33%
o
40%
O
49%
Answer:
40%
Step-by-step explanation:
In order to calculate this probability we need to calculate the frequency of all the numbers rolled that were less than three. Since this would be numbers 1 and 2 and 1 was rolled 6 times while 2 was rolled 8 times, therefore, we add these numbers together.
6 + 8 = 14
Since we are tolled that the total number of rolls were 35, we now divide the number of rolls that were less than 3 (14 rolls) by the total number of rolls made (35 rolls). This would give us the probability of rolling a number less than 3
14 / 35 = 0.4 ... multiply by 100 to get percentage
0.4 * 100 = 40%

. Which function's graph has a vertex at (-1, -3) and contains the point (2, 15)?
HELPPP PLEASEE
Answer:
2(x+1)²-3
Step-by-step explanation:
Using the vertex formula we can write the follwoing equation
y=a(x+1)²-3
We need to solve for a
we know that when x= 2 y = 15
So we can write
15=a(2+1)²-3
15=9a-3
18=9a
a=2
Which means our final equation is
2(x+1)²-3
in standard form (just in case)
2x²+4x-1

Y and x have a proportional relationship, and y = 24 when x = 16 What is the value of x when y = 36?
If y is proportional to x, then;
y = kx
24 = 16k
k = 24/16
k = 1.5
Recall that y = kx
36 = 1.5x
x = 36/1.5
x = 24
Hence the required value of x is 24
