Find the equation of the parabola with its focus shown below. GRAPH ATTACHED, 15 POINTS! Due in 2 hours, will give BRAINLIEST!
Answers
Answer:
Solution : Option A
Step-by-step explanation:
Let' go through all the options we have here.
• x + 2 = - 1 / 8y² converted into standard form will be 4(- 2)(x - (- 2)) = (y - 0)². The parabola properties will be similar to the ones of this parabola, vertex = (- 2,0) and focal length = - 2. It hence is most likely to be the parabola provided to us.
• y = 1 / 8(x + 2)² is an up - down facing parabola, and hence is not at all similar to the given parabola
• x - 2 = 1 / 8y² will be a graph reflected over the y - axis with respect to the graph x + 2 = - 1 / 8y². It hence does not match the given parabola
• y = 1 / 8(x + 2)² will be a graph reflected over the x - axis with respect to the graph of y = 1 / 8(x + 2)². It will hence be a down - up facing parabola, which does not match the given parabola

s 72°
t 119°
Answer:
d = 64°
c = 180° - 64° = 116°
a = 64°
b = 180° - 64° = 116°
m = 180° - 75° = 105°
t = 180° - 61° = 119°
f = 180° - 108° = 72°
g = 108° = e
h = 180° - 108° = 72°
i = j = g = 108°
k = i = 108°
s = 180° - 108° = 72°
n = 79°
p + n + 75° + q = 360° (their vertices form a quadrilateral)
--> q = 360° - 90° - 79° - 75° = 116°
(i see that n,p,q don't have any special relationships at all but i'm not sure about that, sorry)
You hungrily remove frozen meat from the fridge. Its temperature is 28
degrees Fahrenheit. Its temperature is increasing by 3 degrees Fahrenheit
every five minutes. What will its temperature be after 30 minutes?
Answers
You know it increased every five minutes so 30 divided by 5 is 6. That’s 6 times it has increased. 6 multiplied by 3 which is how many degree it’s increased each increment gives you 18. That’s the told it’s increased by 30 minutes. Then add the original temperature which was 28 to 18 which gives you 46.

Consider the equation 3p – 7 + p = 13. What is the resulting equation after the first step in the solution?
p – 7 = 13 – 3p
2p – 7 = 13
3p – 7 = 13 – p
4p – 7 = 13
Answers
Answer:
4p - 7 = 13
Step-by-step explanation:
The first step of the solution should be to simplify the left side by combining like terms. In this case, 3p and p are the like terms and 3p + p = 4p so the answer is 4p - 7 = 13.
Answer:
4p - 7 = 13

Over a period of a week, the 4 people in Group C ran a total of 27 miles, while the
6 people in Group D ran a total of 39 miles. On average, who ran more miles-an
individual in Group C or an individual in Group D?
Answers
Explanation: To find the number of miles per individual, you must subtract the total number of miles by the total number of people who ran those miles. Which ever answer is larger, tells us which group ran more miles an individual.
Here are the calculations-
Group C: 27/4=6.75
Group D: 39/6=6.5
As you can see, Group C ran more miles an individual than Group D.

Answer:
y = 4
Step-by-step explanation:
If two triangles are similar then,
i) Corresponding angles will be equal
ii) Corresponding sides will be in the same ratio.
[tex]\frac{AC}{EF}=\frac{CB}{FD}\\\\\\\frac{12}{y}=\frac{15}{5}\\\\[/tex]
Cross multiply,
12*5 = y*15
y*15 = 12*5
[tex]y=\frac{12*5}{15}\\[/tex]
y = 4
Answer:
∠DEF = 60
x = 11.4
y = 4
Step-by-step explanation:
Step 1: State what is known
The question tells us that Triangle ABC is similar to Triangle EFD, We know similar angles share the same angles and the sides are similar to the corresponding side
Step 2: Find the unknown angle
Because we know the triangles are similar we need to find ∠BAC to solve for 'z'
z = 180 - 55 - 65
z = 60
Step 3: Find the unknown side with the ratio
We know 1 pair of sides BC and DF and it gives us a ratio of BC : DF or 3 : 1
We can set the ratios equal to an unknown side to solve:
3 : 1 = 12 : y
We can multiple 3 : 1 by 4 to get the 'y'
12 : 4
y = 4
3 : 1 = x : 3.8
We can multiple 3 : 1 by 3.8 to get 'x'
11.4 : 3.8
x = 11.4
Therefore ∠DEF = 60, side x = 11.4 and side y = 4
A marathon race is 26.2 miles. While running the marathon, Maxwell stops every 3.25 miles for water. If he has already stopped for water 5 times, how many more miles does Maxwell have to run? PLEASE HELP I WILL MARK YOU BRAINLIEST AND PLEASE EXPLAIN
Answers
Answer:
Hey there!
If he has already stopped five times for water, he has run 5(3.25), or 16.25 miles.
He has 26.2-16.25, or 9.95 more miles to run.
Let me know if this helps :)
Answer:
9.95 miles
Step-by-step explanation:
How many times he stopped × number of miles before break = total miles that has been run.
3.25 × 5 = 16.25
26.2 - 16.25 = 9.95 miles.

Answer:
[tex]T_n = \frac{2^na}{2}[/tex]
Step-by-step explanation:
Given
Bacteria splits to 2 at every 20 minutes
Required
Explain how to get the resulting number of bacteria
To do this we simply make use of geometric progression formula;
[tex]T_n = ar^{n-1}[/tex]
In this case; r = 2 (rate at which they split);
[tex]T_n = a * 2^{n-1}[/tex]
a represents the initial number of bacteria in the dish
Apply law of indices
[tex]T_n = a * \frac{2^n}{2^1}[/tex]
[tex]T_n = a * \frac{2^n}{2}[/tex]
[tex]T_n = \frac{2^na}{2}[/tex]
Assume, we want to determine the number of bacteria at the 10th 20 minutes (in other words, 200 minutes), the value of n will be 10

The local humane society is restocking on cat food to prepare for kitten season. Very young kittens need kitten formula which costs 3.99 per bottle. Older kittens need wet cat food which costs 1.5 per can.
Answers
Answer:
Step-by-step explanation:
A.) Let z be the variable denoted for the total cost of all kitten supplies. Then, let x be the number of bottles and let y be the number of cans. The equation would be:
z = 3.99x + 1.50y
The coefficients are 1 for z, 3.99 for x and 1.50 for y.
There are no constants.
The variables are z, x and y.
Part B.) Substitute x=30 and y=120 to the equation in part A to determine z.
z = 3.99(30) + 1.50(120)
z = $299.7
Part C.
Sales tax would be 7% of the total cost. This would be added as a constant. The expression would be:
z = (3.99x + 1.50y)(1+0.07)
Substituting x=30 and y=120,
z = (3.99*30 + 1.50*120)(1+0.07)
z = $320.679
Goat on a Rope
Farmer Smith has a goat named Mel. He hasn’t had time to put up a fence to contain Mel, so he has Mel tied to a rope in his field. The rope is attached to a pole, allowing Mel to wander within a circular area. The rope is 10 feet long. Farmer Smith remembers that the formula for the area of a circle is A = r2 , and that “r” means the radius of the circle. He wants to know how much grass Mel can eat, so he uses 3.14 for , and calculates the area of the circle. How many square feet of grass can Mel reach while still on his rope? (It might help to draw a picture.)
Answers
Answer:
the area of grass is 314 square feet
Step-by-step explanation:
The radius of the circle the goat can reach is given by the length of the rope that ties the goat to the post (10 ft)
Then the area of the circle is: [tex]Area=\pi\,R^2=3.14\,(10\,\,ft)^2=3.14 * (100)\,ft^2=314 \,\,ft^2[/tex]
So the area of grass is 314 square feet

The parallelogram shown below has an area of 15 squared. Find the missing height. h=? units
Answers
Answer:
5 units
Step-by-step explanation:
The area of a parallelogram is given by the formula:
[tex]A=bh[/tex]
Where b is the base and h is the height.
So we know that the area is 15. We can also see that the base is 3. Thus:
[tex]15=3h[/tex]
Divide both sides by 3:
[tex]h=5[/tex]
So, the height is 5 units.
Answer:
h=3 units
Step-by-step explanation:
Equation for finding the area of a parallelogram:
b·h=area
Equation for this answer:
3·h=15
So divide 15 by 3 and you will get your answer.
15÷3=5
So the answer is:
