Ryan wants to describe the translation shown on the grid below.
On a coordinate plane, triangle X Y Z is shifted 1 unit to the left and 3 units up to form triangle X prime Y prime Z prime.
Ryan uses the following steps to describe the translation.
Step 1 Identify the pre-image and the image:
The pre-image is triangle XYZ, and the image is X prime Y prime Z prime.
Step 2
Identify the number of units that each point moves horizontally:
Each point moves one unit left.
Step 3
Identify the number of units that each point moves vertically:
Each point moves three units down.
Step 4
The translation is one unit left and three units down.

An object is launched from the roof of a building 192
feet above the ground. The object's height (in feet)
after t seconds is given by the function
h(t) = -1672 +64t + 192
B) How many seconds does it take the object to hit the
ground?
Answer:
Unsure, sorry
Step-by-step explanation:
Answer:
t=6
Step-by-step explanation:
h(t) = -16t^2 +64t + 192
We want h(t) =0
0 = -16t^2 +64t + 192
Factor out -16
0 = -16 (t^2 -4t -12)
Factor. What terms multiply to -12 and add to -4 -6*2 = -12 -6+2 = -4
0 = -16(t-6)(t+2)
Using the zero product property
0=t+2 0=t-6
t = -2 t=6
But t=-2 happens before the event occurs so the solution is t=6

Answer:
B
Step-by-step explanation:
Find m∠1 and m∠2. Tell which theorem can be used.
Answer:
angle one=122 because it is using the alternate interior angle theorem
angle 2=58 because it is using the consecutive interior angle theorem
hope this helps
have a good day :)
Step-by-step explanation:
remember consecutive=same sine 122 is on the same side of angle 2 just substract 180-122=58
since 122 is on the opposite side of angle 1 it's going to be alternate something so since it's on the inside its going to be alternate interior angle
Aubrey filled her pool 0.9 of the way with water. Water evaporated from the pool at a rate of 7.5ft ^ 3 per day.
Answer: hello your question lacks vital data hence I will provide you with a general equation within the scope of your question
answer :
General equation = ( Stiver and Mackay or EPA ) evaporation equations
E = [tex]\frac{PAW}{T +459.67}[/tex] or E = [tex]\frac{7.4PA(0.447W)^{0.8} }{T + 459.67}[/tex]
Step-by-step explanation:
Given data
volume of water in pool = 0.9 i.e. 90% full
rate of evaporation = 7.5ft^3 per day = 56.1039 gallons / day
Assumption :
Volume of pool = 16,000 gallons
In order to resolve the missing part of the problem apply the equation below
E = [tex]\frac{PAW}{T +459.67}[/tex] or E = [tex]\frac{7.4PA(0.447W)^{0.8} }{T + 459.67}[/tex]
where : E = Evaporation rate , P = water's vapor pressure , A = pool surface Area , W = wind speed , T = Temperature in Fahrenheit
what does n)-2 mean ??
The letter “n” notates “number” and refers to any number, similar to “x.” The little carat means they the number following, in this case a 2, is an exponent. So this can really be understood as “x squared.” Most likely, this term appeared in an equation.
factor the polynomial below completely.
z^2 + 9z + 20
Answer:
Step-by-step explanation:
z^2+9z+20
=z^2+(5+4)z+20
=z^2+5z+4z+20
=z(z+5)+4(z+5)
=(z+5)(z+4)

Answer:
m∠6 = 110°
Step-by-step explanation:
∠6 and ∠8 are known as corresponding angles meaning they are equal to each other. Since m∠8 = 110°, m∠6 also equals 110°.
Answer:
11o degree
Step-by-step explanation:
angle 6 is 110 degree because the relation between angle 6 and angle 8 is that they are corresponding angles and corresponding angles are always equal.

Answer:
Choice C
Step-by-step explanation:
$80 to 5 hours
Divide both numbers by 5 to find the unit rate:
$16 to 1 hour, or 16 to 1
For x hours, the pay, y, is y = 16x.
Choice A is true.
Look at choice B.
When x = 5, y = 80.
This is correct because we are given that information.
The process is to multiply the hours by 16.
For x hours, y = 16x (from choice A)
For x = 7, y = 7 * 16
Choice B works.
Look at choice C.
We need a proportion. The left side is the ratio 80/5, meaning $80 for 5 hours of work. Notice that the first number in the ratio is dollars, and the second number is hours. Now we need another ratio written in the same order to set up a proportion. x dollars is to 7 hours. This is the ratio x/7. The correct proportion is
80/5 = x/7
Choice C is 80/5 = 7/x
Choice C is incorrect.
Look at choice D.
The graph shows that for 5 hours, the pay is $80, so by looking up x = 7, you can find the correct amount of pay.
Choice D works.
Answer: Choice C

I NEED HELP!!!! Solving quadratics
Answer:
y = ax2 + bx + c
Step-by-step explanation:
1) Standard form: y = ax2 + bx + c where the a,b, and c are just numbers.
2) Factored form: y = (ax + c)(bx + d) again the a,b,c, and d are just numbers.
3) Vertex form: y = a(x + b)2 + c again the a, b, and c are just numbers.
Tommy was solving the triangle below. Which of the following is TRUE about his solution? Help ASAP !!!!
Answer:
The value of x is incorrect he should be using 28/21 instead of 21/28
Step-by-step explanation:
tan = opp/adj
tanx = 28/21
The value of x is incorrect he should be using 28/21 instead of 21/28
Answer:
A) The value of x is incorrect. He should be using 28/21 instead of 21/28.
Step-by-step explanation:
Recall that [tex]tan\theta=\frac{opposite}{adjacent}[/tex]. This means that the correct setup would be [tex]tan\theta=\frac{28}{21}[/tex] since 28 is opposite of x° and 21 is adjacent to x°. Thus, your solution would be [tex]x^{o}=tan^{-1}(\frac{28}{21})=53.13010235^o\approx53.1^o[/tex]
A right triangle's hypotenuse has length 5. If one leg has length 3, what is the length of the other leg?
Answer:
The length of the other leg will be = 4
Step-by-step explanation:
You have to use your Pythagoras theorem to determine the length of the other leg.
Hypotenuse^2=a^2+b^2
since you are given the length of the hypotenuse and one leg you can change the formula to:
b^2 = h^2 - a^2
b = √h^2-a^2
b=√5^2-3^2
b=√25-9
b=√16
b=4

Please help guys!!!!!!!!!!!!!!
Answer:
a) x = -10
b) x = 7
Step-by-step explanation:
a)
2(x + 3) = x - 4
2x + 6 = x - 4
2x - x = -4 - 6
x = -10
b)
4(5x - 2) = 2(9x + 3)
20x - 8 = 18x + 6
20x - 18x = 6 + 8
2x = 14
x = 7
