Answer:
b. y^2 = -12x
Step-by-step explanation:
The general form for the given parabola is y^2 = -4ax where the focus is at (-a, 0). The focal width is 4a which in this case = 12.
Sally can run 5 km in 25 minutes. At the same rat of speed, how far can she run in 2 hours and five minutes?
Answer:
25 km
Step-by-step explanation:
[tex]\frac{5}{25} :\frac{y}{125}[/tex]
y · 25 = 5 · 125
25y = 625
25y ÷ 25 = 625 ÷ 25
y = 25
Sin0=20/29 find tan 0
Answer:
Step-by-step explanation:
here opposite =20, hypotenuse=29
to find adjacent use formula
a^2+b^2=c^2
20^2+b^2=29^2
400+b^2=841
b^2=841-400
b=[tex]\sqrt{441\\}[/tex]
b=21
tan theta=opposite/adjacent
=20/21
therefore tan theta =20/21
Answer:
D. tanθ = 20/21
Step-by-step explanation:
Remember that sinθ = opposite/hypotenuse. In this case, since sinθ = 20/29, we are going to say that opposite = 20 and hypotenuse = 29.
To solve for the adjacent side, use the Pythagorean theorem, a^2 + b^2 = c^2.
When you plug in your values and solve for the other leg, you'll get 21.
Now that we know that the adjacent side/other leg is equal to 21, we can find tanθ, since it's equal to opposite/adjacent.
Opposite = 20
Adjacent = 21
tanθ = 20/21

For the data that are shown on the graph below, which best describes within which range of x-values extrapolation occurs? On a graph, points are at (0, 15), (1, 17), (3, 18), (4, 20) and (6, 22). x greater-than 6 x less-than 0 and x greater-than 6 x less-than 0 and x greater-than 10 x greater-than-or-equal-to 0 and x less-than-or-equal-to 6 Mark this and return
Given:
On a graph, points are at (0, 15), (1, 17), (3, 18), (4, 20) and (6, 22).
To find:
The range of x-values extrapolation occurs.
Solution:
Consider the below figure attached with this question.
From the graph or given points it is clear that the x-values are 0, 1, 3, 4, 6.
It means the x-values are from 0 to 6.
So, the range of the x-values is [tex]x\geq 0[/tex] or [tex]x\leq 6[/tex].
The required compound inequality for the range of x-values is [tex]0\leq x\leq 6[/tex].
Therefore, the correct option is D.

The perimeter of a certain square is 4 yards. Find the area of the square in square feet.
Please someone help
Step-by-step explanation:
Write what you know
A square has 4 sides
the perimeter is the sum of the length of all 4 sides
so 4yards / 4 sides = 1 yard per side
we also know a square has all equal sides
that means our area formula will be 1 x 1

Answer: The slope between these two is 3.5
Answer:
Solpe=4.5
Step-by-step explanation:
Sorry if I’m wrong, but I think I got it.
So the formula for slope is y2-y1/x2-x1
In (-3,-2) )-7,-16), -3 is x1, -2 is y1, -7 is x2, and -16 is y2.
Now, you need to fill in the formula with these numbers.
-16-2/-7- - 3
-16-2 is -18
-7- - 3 is -4 (two negatives make a positive)
This makes -18/-4. Divide this to get 4.5.

Mayra bought a pair of sneakers. They originally cost $75 but were on sale for 15% how much mony did she save
Answer: $11.25
Step-by-step explanation:
Since the sneakers were on sale for 15% less, the amount she bought them will be:
= (100% - 15%) × $75
= 85% × $75
= 0.85 × $75
= $63.75
Therefore, the amount she saved will then be:
= $75 - $63.75
= $11.25
She saved $11.25

Amanda graphed line m and line n on a coordinate plane, as shown below.
Which of the following statements is true?
A. The slope of line m is greater then the slope of line n
B. The slope of line n is greater than the slope of line m
C. The x-intercept of line m is greater then the x -intercept of line n
D. The y-intercept of line n is greater then the y -intercept of line m.
Answer:
B
Step-by-step explanation:
To find the slope of the line, we do y2-y1/x2-x1. In this case, for line n, I used the points (0,0) and (1,2). This means the slope will be 2-0/1-0. Simplify this to get 2/1 or 2. Therefore the slope for line n is 2.
To find the slope of the line, we do y2-y1/x2-x1. In this case, for line m, I used the points (0,7) and (1,8). This means the slope will be 8-7/1-0. This will make the slope 1/1 or 1. Therefore, the slope for m is 1.
Therefore, the slope for line n is greater than the slope of line m.

Step-by-step explanation:
Jim was thinking of a number. Jim doubles it, then adds 19 to get an answer of 70.1. What was the original number?
Answer:
25.55
Step-by-step explanation:
Let us take the number he thinked of be x .
On doubling it :-
→ N = 2x
On adding 19 :-
→ N = 2x + 19
According to Question :-
→ 2x + 19 = 70.1
→ 2x = 70.1 - 19
→ 2x = 51.1
→ x = 51.1/2
→ x = 25.55
Hence the required answer is 25.55How many 2/3 of a foot are in 18,491 feet? pls help!!!!!!!!

Select all expressions equivalent to 8x - 24.
2(2x - 12)
4(2x - 4)
8(x - 3)
2(4x - 12)
Answer:
8(x-3)
2(4x-24)
Step-by-step explanation:
You are using the distributive property. Multiply the number outside of the parentheses by each number within the parentheses.
In 8(x-3) = 8x - (8×3) = 8x-24
In 2(4x-12) = (2 × 4x) - (2 × 12) = 8x-24
