Identify the vertex and axis of symmetry.
f(x) = 3(x+7)²-5
Answer:
haiii i can only solve for the vertex...
Step-by-step explanation:
so to find the vertex you have to make it to
y - h = a(x - k)^2
i think
(you could also just make it y = a(x - k)^2 + h but i like the second one better)
soo
y + 5 = 3(x + 7)^2
the vertex is
(-7, -5)
and ummm i think the axis for the axis of symmetry .ss
x = 2a/b but im not sure

ABC with vertices A(-6, -8), B(0, 4), and C (-6, 10) is dilated so that A’ is
now (-15, -20). What was the
dilation, and where are B’ and C’?
Answer:
scale factor = 2.5 and b` is now (0,10) and c` is (-15, 25)
Step-by-step explanation:
You first want to divide -15 and -6, the x values of a and a`. this will give you the scale factor. then multiply every other number by the scale factor to get the points for b` and c`.

Approximate square root 18 to the nearest hundredth. Be sure to show all of your work.
Answer:
The square root of 18 with one digit decimal accuracy is 4.2.
Step-by-step explanation:
Answer:
4.24 (nearest hundredth)
Step-by-step explanation:
Step 1
Square numbers: 1, 4, 9, 16, 25, 36, ...
Find the perfect squares either side of 18:
16 and 25As [tex]\sf \sqrt{16}=4[/tex] and [tex]\sf \sqrt{25}=5[/tex] then [tex]\sf 4 < \sqrt{18} < 5[/tex]
Step 2
Divide 18 by one of the two square roots in step 1 (4 or 5):
⇒ 18 ÷ 4 = 4.5
Step 3
Find the average of the root (4) and the result (4.5):
[tex]\sf \implies \dfrac{4+4.5}{2}=4.25[/tex]
Repeat steps 2 and 3:
Divide 18 by the solution of step 3. Then find the average of this and the solution of step 3:
⇒ 18 ÷ 4.25 = 72/17
[tex]\sf \implies \dfrac{4.25+\frac{72}{17}}{2}=\dfrac{577}{136}=4.242647059[/tex]
Repeat:
⇒ 18 ÷ 577/136 = 2448/577
[tex]\sf \implies \dfrac{\frac{577}{136}+\frac{2448}{577}}{2}=4.242640687[/tex]
As the approximate square root needs to be to the nearest hundredth, we do not need to keep repeating the steps.
Therefore, √18 ≈ 4.24 (nearest hundredth)

Answer:
17662.5 sq. feet
Step-by-step explanation:
We know that the formula for Area of a Circle is [tex]A = \pi (r)^2[/tex].
r = radius; d = diameter, which is r*2
And so, in the question, it gives you that the diameter is 150, first we divide it by 2 to get the radius.
150/2 = 75
The question said to keep [tex]\pi[/tex] =3.14, so then we plug in the equation-
[tex]A = 3.14 * 75^2[/tex]
Then we use PEMDAS [Parenthesis; Exponents; Multiply & Divide; Add & Subtract] which would get us-
[tex]A = 3.14 * 5625[/tex] (first doing the Exponent)
And we continue-
[tex]A = 17662.5[/tex] (then multiple)
So our answer is-
17662.5 sq. feet
I hope this helps!

At noon, a team bus left City College for their opponent's school. Soon thereafter, City's first-line player Brett Starr arrived at the gym. A loyal day-student parent volunteered to overtake the bus and deliver Brett. The two left at 12:15 pm. The parent drove at 54 mph, while ahead of them the yellow bus poked along at 48 mph. Did the car catch the bus before it reached the game, which is 110 miles from City college? If so, where and when?
Answer:
No, the car didn't catch the bus, as their time and distance traveled doesn't intersect when portrayed on a graph.
Step-by-step explanation:
It would take the car approximately 2.14 hours to catch up to the bus. Since the car left at 12:15 pm, it should have caught up to the bus at 2:29 pm.
What is the average speed?Average speed is calculated by dividing a quantity by the time required to obtain that quantity. Meters per second is the SI unit of speed. The formula S = d/t, where S is the average speed, d is the total distance, and t is the total time, is used to determine average speed.
Yes, the car was able to catch up to the bus before it reached the game. With the car travelling at 54 mph and the bus travelling at 48 mph, the car is travelling 6 mph faster than the bus. In order to calculate how long it would take for the car to catch the bus, we use the formula for average speed:
Average speed = (speed of car + speed of bus) / 2
Average speed = (54 mph + 48 mph) / 2
Average speed = 51 mph
Now, we can use the formula for distance travelled over time to calculate how long it would take the car to travel the 110 miles to the game:
Distance = Rate x Time
110 miles = 51 mph x Time
Time = 110 miles / 51 mph
Time = 2.14 hours
Therefore, it would take the car approximately 2.14 hours to catch up to the bus. Since the car left at 12:15 pm, it should have caught up to the bus at 2:29 pm.

Mona had $20.00. She bought one loaf of bread for $2.25, a gallon of milk for $4.39, and a carton of eggs for $1.19. How much change should she get back?
Answer:
She should get $12.17 in change.
Step-by-step explanation:
20- 2.25 = 17.75
17.75 - 4.39 = 13.46
13.46 - 1.19 = 12.17

-8 1/3 + 3 2/5
lol i need a refresh when you multiply the fraction to get it to be added with the other one do you multiply the whole number too?
Answer:
-81/3+32/5
-81×5+32×3/15
-243+96/15
-147/15
-49/5 Ans
To answer your question ("do you multiply the whole number too?"): Yes, you have to multiply the whole number as well. You can't just separate 1/3 from -8 and multiply it with 2/5, because the whole number is part of the mixed #. Whenever you multiply, add, divide, subtract, or do anything to two mixed numbers, you must include the whole term.
- - - - - - - - - -
Now your question is addition. Like I said, when you add them together, the whole number and the fractions count as one term.
So basically, -8 1/3 + 3 2/5...
- - - - - - - - - -
1) Find the LCM (least common multiple) of the denominators
The LCM of 3 and 5 is 15. To get from 3 to 15, you have to multiply 3 by 5. Now multiply the numbers of the fraction part only by 5.
1/3 --> 5/15 (as you can see, 1x5 = 5, 3x5 = 15)
Now for 2/5: To get from 5 to 15, multiply 5 by 3. Do the same thing to the numbers in the fraction
2/5 --> 6/15 (2x3 = 6, 5x3 = 15)
***TO CLARIFY, DO NOT MULTIPLY THE WHOLE TERM BY THE NUMBER***
Right: 2x3 = 6, 5x3 = 15, 6/15
Wrong: 2/5 x 5 = 2
- - - - - - - - - -
2) So now that we found a common denominator, change the two terms to -8 5/15 + 3 6/15 (because we had to find the LCM to make life a lot easier)
- - - - - - - - - -
3) We just add them together. Even though they are a term together, you can split them apart and add them together separately thanks to the commutative property of addition*.
Time to split it apart to make life a whole lot easier. -8 5/15 can be split apart into the two terms -8 and 5/15. For 3 6/15, it can be split into 3 and 5/15.
Two options from here on:
Set up a single equation: Put all the terms into one equation. -8 + 3 + 5/15 + 6/15. Solve by adding all the terms together in whichever order you prefer (again, thanks to the commutative property of addition)
It would result in the answer -4 4/15
Or...
Set up two separate equations: Set up an equation for whole numbers, and another one for fractions.
Equation 1: -8 + 3 = -5
Equation 2: 5/15 + 6/15 = 11/15
(6 + 5 = 11)
And we add the sums together. -5 + 11/15 = -4 4/15
And that's it!
- - - - - - - - - -
*Commutative Property of Addition: The sum of the numbers will NOT change even if you change the order of the addends

the table shows the results of rolling a number cube labeled 1 through 6 30 times
based on the results, if the cube roles 200 times, how many times is it expected to land on 1
Answer:
40 times
Step-by-step explanation:
To figure this out, divide 6 by 30, then multiply by 200
(6/30)200 = 40
This also works: (200/30)6 = 40
We divide 6 by 30 because we landed on the 1 side 6 times out of 30. We then multiply 6/30 by 200 because it is out of 200 this time, so we will multiply 6 by 200 then divide by 30. 200(6) = 1200. 1200/30 = 40.

how do you find the fist step to solving the system of equations x+y=8 and 3x-2y=-6
Answer:
The first stpe in solving this system of equations is finding either X or Y in terms of the other variable. Ex: x = 8 - y or y = 8 - x
Step-by-step explanation:
When faced with a system of equations problem, you need to find one variable at a time. To do this, you need to eliminate one of the variables from one of the equations. I used x + y = 8 because that was simplier to find one of the variables from. From there, you can substitute that in for the variabel in the secone equation.
3x - 2y = -6
3x - 2(8 - x) = -6
3x - 16 + 2x = -6
5x - 16 = -6
5x = 10
x = 2
Than you can use that and plug it back into one of the original equations to find the other variable.
x + y = 8
2 + y = 8
y = 6

If you roll a fair number cube 30 times, what is the experimental probability of rolling a 2
Answer:
1/6 chance or 16.667% chance
Step-by-step explanation:
a fair number cube has six sides so if you roll that 30 times that's 180 sides and the probability of rolling a 2 out of a single dice is 1/6 and since 180 * 1/6 is equal to 30 that is 30 out of 180 which is 1/6
Given: KLMN is a trapezoid, KL=MN, angle 1 = angle 2, LM/KN = 8/9, Perimeter = 132. Find the length of the legs
Answer:The length of midsegment is 34 units.
Given data:
The trapezoid KLMN, Such that KL = MN.
And , LM/KN = 8/9
Also, perimeter of KLMN = 132 units.
To find:
The length of midsegment (KM).
In the given problem, we can observe that KM is a transversal relative to parallel lines LM and KN. Which means,
Clearly, two base angles are equal. So, the triangles KLM and KMN are isosceles.
Taking the ratios of sides of two triangles as,
= KL : LM : MN : KN
= 8 : 8 : 8 : 9
The sum of ratio units is, 8 + 8 +8 +9 = 33. Then, the value of each ratio is,
Then the length of segment LM is,
And, length of segment KN is,
Then, the length of midsegment KM is obtained by taking the average of LM and KN as,
Thus, the length of midsegment is 34 units
