Answer:
The parabola has an absolute minimum and its vertex is located at (1, 7).
Step-by-step explanation:
Since the directrix is below the focus, we infer that parabola has an absolute minimum, where there is a vertex, which is the midpoint of the line segment between (1, 10) and (1, 4). By definition of midpoint, we conclude that vertex is located at (1, 7).
What is the median of the first half of the data? (first quartile)
Answer:
$273
Step-by-step explanation:
1. Find the first half of the list (There are 8 numbers in the list, so the first four)
2. List them from least to greatest ($196, $248, $298, $379)
3. find the middle of the numbers ($248, $298)
4. Since there are 2, we find the mean of the 2 numbers ($273)
5. So the answer is $273

What is the slope for this question?
Answer:
[tex]-1[/tex]
Step-by-step explanation:
This is a really nice line that goes through a lot of grid points (where the lines intersect).
One easy way to find the slope is the phrase "rise over run." "Rise" is the name for vertical motion from point-to-point. "Run" is the name for horizontal motion from point-to-point.
Pick two easy points on the line, say (0, 0) and (1, -1).
If you go from (0, 0) to (1, -1), the rise is -1 -- because you went DOWN 1 unit.
The run is 1 -- because you went RIGHT 1 unit.
[tex]\frac{\text{rise}}{\text{run}} =\frac{-1}{1} =-1[/tex]
The slope is -1.
Cool fact: You'll get the same value if you use any two points on the line.

True or False: The area of a circle with diameter d = 2r = 10 is greater than the area of an ellipse with major axis 2a = 10. Explain your answer. Note: the area of an ellipse is calculated with the formula = (with ‘a’ the length of the semi-major axis and ‘b’ the length of the semiminor axis). Explain why as well.
Answer:
True
Step-by-step explanation:
So the radius would be 5 (as you times it by 2 to get 10)
Therefore
2a=10 is the same as what the circle with diameter d=2r=10

If a tank leaks 10 mL of fluid each hour, how long will it take to fill up a one-litre jar?
10 hours
1,000 hours
1 hour
100 hours
Answer:
100 hours
Step-by-step explanation:
To find the amount of liters in one hour, you divide 10 by 1000, which gives 0.01 liters each hour. From here, the 1 is in the hundredths place, so if you multiply by 100 hours, if will be at 1 liter.
Find the Average
100-90-80-89-75-0
Explain how u got ur answer
Someone help I will give brainlist for whoever explains it
Answer:
72.3
Step-by-step explanation:
So, to find the average you need to add all the numbers together and divide it by the amount of numbers there are, if that makes sense.
so in your question: 100 + 90 + 80 + 89 + 75 + 0= 434
and there are 6 numbers that you had to add together, so you divide 434 by 6, which is 72.3 so that's the answer! It's quite easy once you understand how to do it :)

Put these numbers in order, from least to greatest. If you get stuck, consider using the number line. with a picture
Answer:
Step-by-step explanation:
When we proceed from left to right on a number line, numbers get bigger.
That means (-5) on the given number is the least and 5 is the greatest.
By this rule, order of the numbers will be,
-4.2, -3.5, -2.1, -1.5, -1, -0.5, 0.5, 3.5, 4.8
Now we can place these numbers on the number line as shown.

Write a function for the line with a slope of −14 that passes through the point (4, 5)
Answer:
y = -14x + 61
Step-by-step explanation:
y = mx + b
First, we can find the slope by reading the question and plugging in the slope of -14 into a slope-intercept formula.
y = (-14)x + b
Now, we need to find the "b" value. We can plug anything we want in for x and y here, but we want the equation for the line that passes through the the point (4,5). Plug in 4 into the x value and 5 into the y value, and solve for b.
5 = (-14)(4) + b
(Flip the equation, so we can solve for b.)
b = 5 - (-14) (4)
(Multiply.)
b = 5 - -56
(Substitute the double minus for a plus sign and add.)
b = 5 + 56
b = 61
Now, plug in your "b" value into our original equation.
FINAL ANSWER:
y = -14x + 61
The point (- 3, 6) is on a circle with a center at (2, 3) What is the equation of the circle?
Answer:
[tex](x - 2)^{2} + (y - 3)^{2} = 36[/tex] is the equation of the circle
Step-by-step explanation:
[tex](x - h)^{2} + (y - k)^{2} = r^{2}[/tex] where (h, k) is the center and r is the radius
In this case h = 2 and k = 3 and r = 6 (see below)
r adius =
[tex]\sqrt{(2 + 3)^{2} + (3 - 6)^{2} } \\= \sqrt{5^{2} + (-3)^{2} } \\= \sqrt{25 + 9\\}\\ = \sqrt{36} = 6[/tex]
Therefore, [tex](x - 2)^{2} + (y - 3)^{2} = 36[/tex] is the equation of the circle
The point (- 3, 6) is on a circle with a center at (2, 3) So, the equation of the circle will be (x-2)^{2} +(y-3)^{2}= 6^{2}.
What is the general equation of a circle?The general equation of a circle of radius represents all the points that lie on the circumference of the given circle.
The general equation of a circle is:
[tex]\rm (x-h)^{2} +(y-k)^{2}= r^{2}[/tex]
where (h, k) is the center and r is the radius
The point (- 3, 6) is on a circle with a center at (2, 3).
here, h = 2 and k = 3
[tex]\sqrt{(2+3)^{2} +(3-6)^{2}} \\\\\sqrt{5^2+3^2} \\\\\sqrt{36} \\\\6[/tex]
therefore, the radius is 6 units.
Now, the equation of a circle is:
[tex]\rm (x-h)^{2} +(y-k)^{2}= r^{2}[/tex]
[tex]\rm (x-2)^{2} +(y-3)^{2}= 6^{2}[/tex]

Identify the lateral area and surface area of a right cone with radius 6 cm and slant height 13 cm.
Answer:
The lateral surface area is about = 269.747749 m squared
The surface area is about = 382.787749 m squared
Step-by-step explanation:
Answer:
L = 245 cm2 ; S = 358.1 cm2
Step-by-step explanation:
The lateral area of a right cone with radius r and slant height l is L=πrl.
The figure shows a right cone.
Apply the formula for the lateral area of a right cone L=πrl.
Substitute the known values for the radius r=6 cm and the slant height l=13 cm.
L=π(6)(13)=78π
Use a calculator to approximate. Round your answer to the nearest whole number.
L≈245
The lateral area of the cone is 245 cm2.
The surface area of a right cone with lateral area L and base area B is S=L+B, or S=πrl+πr2.
Substitute the given value for the radius r=6 cm into the formula for the area of a circle, B=πr2.
B=π(6)2=36π
Therefore, the base area is 36π cm2.
To calculate the surface area of the cone, substitute the known values into formula for surface area.
S=78π+36π=114π
Use a calculator to approximate. Round your answer to the nearest tenth.
S≈358.1
Therefore, the surface area of the cone is about 358.1 cm2.
