Answer:
D. 36 units
Step-by-step explanation:
Using the distance formula, we find the length of AB to be ...
d = √((x2 -x1)² +(y2 -y1)²)
d = √((7-(-2))² +(-3-9)²) = √(81 +144) = √225 = 15
The line BC is horizontal, so its length is the difference of the x-coordinates:
BC = 7 -(-2) = 9
The line AC is vertical, so its length is the difference of the y-coordinates:
AC = 9 -(-3) = 12
The sum of the lengths of the sides of the triangle is ...
P = 15 + 9 + 12 = 36
The perimeter is 36 units.

Write the final equation using the slope-intercept form perpendicular to 3y = x − 4 and passes through the point (−2, 1)
Answer:
y=-3x-5
Step-by-step explanation:
given equation:
3y=x-4
slope intercept form is y=mx+b
(m is the slope, b is the y intercept)
divide by 3
y=1/3x-4/3
perpendicular lines have slopes that are negative and reciprocal. If you multiply them together, the result is -1.
so to find the slope of the perpendicular line, use this equation:
1/3m=-1
multiply by 3
m=-3
the slope of the new line is -3.
here is our equation so far:
y=-3x+b
now, we need to find b.
Since the equation of the line passes through the point (-2,1) we can substitute that into the equation to find b
1=-3(-2)+b
multiply
1=6+b
subtract 6
-5=b
so the line is y=-3x-5

Dilation scale factor is 2
hope this helps :)
please mark branliest
Step-by-step explanation:
Answer:
2
Step-by-step explanation:
To find the scale factor of a dilation, we first have to find two corresponding sides. For example, the top edge of the black shape corresponds with the top edge of the green shape. The length on the black shape measures 7 units and the length on the green shape measures 14 units.
Now, we divide the length taken from the figure by the length taken from the original shape.
14/7=2
Therefore, the scale factor of the dilation is 2.

What’s the domain and range of this graph?
Given:
The graph of a downward parabola.
To find:
The domain and range of the graph.
Solution:
Domain is the set of x-values or input values and range is the set of y-values or output values.
The graph represents a downward parabola and domain of a downward parabola is always the set of real numbers because they are defined for all real values of x.
Domain = R
Domain = (-∞,∞)
The maximum point of a downward parabola is the vertex. The range of the downward parabola is always the set of all real number which are less than or equal to the y-coordinate of the vertex.
From the graph it is clear that the vertex of the parabola is at point (5,-4). So, value of function cannot be greater than -4.
Range = All real numbers less than or equal to -4.
Range = (-∞,-4]
Therefore, the domain of the graph is (-∞,∞) and the range of the graph is (-∞,-4].

The picture shows us that the shape is a square.
To find the area of a square you would use the formula s^2
s= 8ft
8ft^2 = 64ft^2
with area you would need to use the unit ft^2
I hope this helps!!!
Answer: DDDDDDD
Step-by-step explanation: The formula is width x height, so we can use the expression 8 x 8 assuming this is perfectly square. 8 x 8 is 64 square units
What expression is equivalent to
4/9(2n - 3)
Answer:8/9 n- 12/9
Step-by-step explanation: You do distributive property.Which is 4/9 times 2 n but you make both 4/9 and 2 to a fraction which is 4/9 times 2/1 which gives you 8/9 .Next you do 4/9 times 3 but make to a fraction both which is 4/9 times 3/1 which gives you 12/9 .Next you take the 8/9 n and 12/9 and you subtract it .Which gives you 8/9 n- 12/9 as your expression.

If Y varies directly with X,
find y when X =24 if y =5
when X = 30.
Answer:
We get Y=4 when X =24
Step-by-step explanation:
If Y varies directly with X, find Y when X=24, if Y = 5 when X= 30.
We are given If Y varies directly with X, we can write:
[tex]Y\:\alpha\: X\\Y=kX[/tex]
Where k is constant of proportionality
We need to find Y when X=24, first we need to find k, the constant of proportionality.
Now, we are given: If Y = 5 when X= 30.
We can find value of k
[tex]Y=kX\\5=k(30)\\k=\frac{5}{30}\\k=\frac{1}{6}[/tex]
So, k=1/6
Now, we will find Y when X = 24
and k=1/6
[tex]Y=kX\\Y=\frac{1}{6}(24)\\Y=4[/tex]
So, Y=4 when X =24.

Write the ratio of stars to squares in all 3 forms (remember to simplify).
Answer:
Step-by-step explanation:
From the picture attached,
Number of stars = 3
Number of squares = 5
Ratio of stars to squares can be written in three forms as,
Number of stars to number of square = 3 to 5
Number of stars : Number of squares = 3 : 5
[tex]\frac{\text{Number of stars}}{\text{Number of squares}}=\frac{3}{5}[/tex]
Given sin x = 8/10, 90° <x< 180° and tan y = -12/5, 270° ≤y≤ 360°. Without finding the values for angle x and y, determine cos x cos y + sin x sin y / tan x - tan y.
Answer:[tex]-\frac{189}{208}[/tex]
Step-by-step explanation:
Given
[tex]\sin x=\frac{8}{10}[/tex]
x lies in the second quadrant where sin and cosec is positive and rest trigonometric functions are negative
so, [tex]\cos x=-\sqrt{1-sin ^2 x}\\\cos x=-\sqrt{1-(\frac{8}{10})^2}=-\sqrt{\frac{36}{100}}\\\cos x=-\sqrt{\frac{6}{10}}[/tex]
[tex]\tan x=\frac{\sin x}{\cos x}=-\frac{4}{3}[/tex]
similarly, [tex]\tan y=-\frac{12}{5}[/tex]
Also, y lies in 4 th Quadrant where cos and sec is positive and rest trigonometric functions are negative
[tex]\sec y=\sqrt{1+\tan ^2y}=\sqrt{1+(-\frac{12}{5})^2}\\\sec y=\frac{13}{5}\\\cos y=\frac{5}{13}\\\sin y =\frac{\tan y}{\cos y}=-\frac{12}{13}[/tex]
Now putting the values
=[tex]\dfrac{\cos x \cos y+\sin x\sin y}{\tan x-\tan y}=\dfrac{(\frac{-6}{10})(\frac{5}{13})+(\frac{8}{10})(\frac{-12}{13})}{(\frac{-8}{6})-(\frac{-12}{5})}\\\dfrac{\cos x \cos y+\sin x\sin y}{\tan x-\tan y}=\dfrac{\frac{-126}{130}}{\frac{16}{15}}=-\frac{189}{208}[/tex]

It takes Maria 10 hours to pick forty bushels of apples. Kayla can pick the same
amount in 12 hours. How long will it take if they work together? Round your answer
to the nearest tenths place.
Answer:
5.3
Step-by-step explanation:
It will take a time 0f 5.5 hours to pick 40 bushels of apple if they worked together.
What is Proportion?Proportions are defined as the concept where two or more ratios are set to be equal to each other.
Suppose we have two ratio p : q and r : s.
If both these ratios are proportional, then we can write it as p: q : : r : s.
This is same as p : q = r : s or p/q = r/s
Given that,
Amount of bushels picked by Maria in 10 hours = 40
Amount of bushels picked by Maria in 1 hour = 40/10 = 4
Amount of bushels picked by Kayla in 12 hours = 40
Amount of bushels picked by Maria in 1 hour = 40/12 = 3.333
Amount of apple picked by both Maria and Kayla in 1 hour if they worked together = 4 + 3.333 = 7.333
Let x be the time taken to pick 40 bushels of apple by both.
Using proportional concept,
x / 40 = 1 / 7.333
x = 40 / 7.333
x = 5.4548 ≈ 5.5 hours
Time taken if they both worked together is 5.5 hours.
