Find the equation of the parabola with focus (5,0) and directrix x =5
Answer:
y²=20x
Step-by-step explanation:
Note: I'm assuming you mean x=-5 for the directrix because what you're asking isn't possible
Since we are given a horizontal directrix, the parabola must also be horizontal.
Horizontal Parabola:
(y-k)² = 4p(x-h)
Vertex: (h, k)
Focus: (h+p, k)
Directrix: x = h - p
Since the focus of the parabola is (5,0), then k=0 and h+p=5. We also know that since the directrix is x=-5, then -5=h-p. If we set these equations equal to each other, we can solve for h and p:
h+p=5
h-p=-5
2p=10
p=5
Since p=5, then h=0. Therefore, we have for our equation of the parabola:
(y-k)² = 4p(x-0)
(y-0)² = 4(5)(x-0)
y²=20x

Answer:
47. C. 30
48. D. 50
49. A. 10
50. A. 10
Step-by-step explanation:
47. The point in the middle of the box is the median, 30
48. The range is the last dot - the first dot outside of the box, 50 - 0 = 50
49. The interquartile range is the range inside the box, the first dot in the box is between 20 and 30, 25. The last dot in the box is between 30 and 40, 35.
35 - 25 = 10
50. Test A's median is 30, Test B's median is 40. 40 - 30 = 10

Find the y-intercept for the parabola defined by
this equation:
y=x^2+ 7x + 6
Separate the values with a comma.
Answer:
(0,6)
Step-by-step explanation:
because a point that lies on y axis has the coordinates of its x = 0.
the therm without the x in the equation of the parabola indicate where it intercepts the y axis
Which expression means the same as "the quotient of 8 less than x and 4"?
Answer:
(x - 8) -4
Step-by-step explanation:
Calculate (0.25) x (0.44). Show your work.
Answer:
0.11
Step-by-step explanation:
0.44/x=100/25
(0.44/x)*x=(100/25)*x
0.44=4*x
0.44/4=x
0.11=x

Its was estimated that 250 people would attend the movie, but 235 people actually attended. What is the percent error, to the nearest percent, of the estimate?
Answer:
the percent error is 6%
Step-by-step explanation:
Given that
The estimated people who attend the movie is 250
And, the people who actually attended is 235
We need to find out the percent error
So
Percent error is
= (250 - 235) ÷ (235)
= 6.38%
= 6%
Hence, the percent error is 6%

u = 6i – 10j
g= -81 – 11j
Find: -3u + 5g
Answer:
[tex]-3u + 5g =-58i -25j[/tex]
Step-by-step explanation:
Given
[tex]u = 6i - 10j[/tex]
[tex]g=-8i - 11j[/tex]
Required
[tex]-3u + 5g[/tex]
We have:
[tex]-3u + 5g[/tex]
This gives:
[tex]-3u + 5g = -3(6i - 10j) + 5(-8i - 11j)[/tex]
Open bracket
[tex]-3u + 5g = -18i + 30j - 40i - 55j[/tex]
Collect like terms
[tex]-3u + 5g = -18i - 40i+ 30j - 55j[/tex]
[tex]-3u + 5g =-58i -25j[/tex]

Let the function [tex]f(x)= 3x + 2[/tex] and [tex]g(x) = \frac{x+3}{2x-10}[/tex] , determine:
Answer:
Given
f(x) = 3x + 2g(x) = (x + 3) / (2x - 10)#1
g · f(x) = g(f(x)) = (3x + 2 + 3)/ (2(3x + 2) - 10) = (3x + 5) / (6x - 6)#2
f · g(x) = f(g(x)) = 3[(3x + 2) / (2x - 10)] + 2 = (9x + 6) / (2x - 10) + 2 = (9x + 6 + 4x - 20)/ (2x - 10) = (13x - 14) / (2x - 10)NEED HELP ASAP OR NOW!!!
1. Which of the following statements best represents the graph?
A. After one month of service, the cost of internet is $45.
B. After 60 months of service, the cost of internet is $1.
C. After one months of service, the cost of internet is $60.
D. After 5 months of service, the cost of internet is $210.
PLEASE ALSO ANSWER THE QUESTION BELOW.
2. Which is the correct equation best reflects to the graph above on question 1?
A. Y = 90x
B. Y = 180x
C. Y = 45x
D. Both B and C

Answer:
A. After one month of service, the cost of internet is $45.
Step-by-step explanation:
If you count on the graph, it goes up 1.5 and over (right) 2. This means to get from 2 months to 1 month, you would go DOWN 1.5 and LEFT 2, which gets you at $45 dollars for the first month.
Which is a reasonable first step that can be used to solve the equation 4 x + 3 (x + 2) = 5 (2 x minus 3)? Distribute the 3 to x + 2, and distribute the 5 to (2x – 3). Combine 4x and x on the left side of the equation. Apply the subtraction property of equality to move the 2 from the left to the right side of the equation. Apply the addition property of equality to move the 3 from the right to the left side of the equation.
Answer:
Distribute the 3 to x + 2, and distribute the 5 to (2x – 3).
Step-by-step explanation:
Given
[tex]4x + 3(x + 2) = 5(2x - 3)[/tex]
Required
Reasonable first step
The reasonable first step is to open the brackets; i.e. distribute 3 to its bracket and 5 to its bracket.
This gives:
[tex]4x + 3(x + 2) = 5(2x - 3)[/tex]
[tex]4x + 3x + 6 = 10x - 15[/tex]
Then the solution can be continued
Answer:
Distribute the 3 to x + 2, and distribute the 5 to (2x – 3).

The third column is labeled g (x) with entries one-half, 2, 8, 32, 128. A 3-column table has 5 rows. The first column is labeled x with entries negative 2, negative 1, 0, 1, 2. The second column is labeled f (x) with entires 128, 32, 0, 2, one-half. The third column is labeled g (x) with entries one-half, 2, 0, 32, 128. A 3-column table has 5 rows.

9514 1404 393
Answer:
2 times
Step-by-step explanation:
Other things remaining the same, the volume of any prism is proportional to its height. If you double the height, it is like having two prisms of the same size. The volume doubles. The new volume is 2 times the original volume.

PLEASE HELP ME: a tea infuser is a right pyramid 7.9 cm tall. it's base is a rectangle 3.0 cm long and 15 cm wide. to make 1 cup of tea, the infuser must be 80% filled with tea. how many cups of tea can you make with a 100 ml tea container if you use this?
Answer:
Full volume is:
V = 1/3lwh V = 1/3*30*15*7.9 = 1185 cm³80% of the volume of the infuser:
1185*0.8 = 948 cm³We know 100 ml = 100 cm³
Number of cups:
948/100 ≈ 9.5 cupsIf you need a whole number then the answer is 9 cups
Note: The length of 3.0 cm doesn't make sense so changed it to 30 cm
