Answer:
A. 56
Step-by-step explanation:
If you look at the image, I cut the shape in half.
So the shape on the bottom not can be multiplied as such: 8x2x2
8x2=16 then 16x2=32.
Since the shape cut in half, the sides are now 2 instead of 4.
Now you can multiply the top shape by: 2x6x2
2x6=12 then 12x2=24.
After you have the volume of both shapes, you add the volumes together.
32+24=56 Then your answer should be A. (Hope this helps!)
Answer:
To find the quadratic equation:
Assume any point (x, y) on parabola.
Use the distance formula i.e, 
Distance between (x , y) and focus 
is:
Now, the distance between (x, y) and directrix of y = 
is:
On the parabola these distance are same;
=
or
Simplify:
Simplify:
or
Divide both sides by 16 we get;
or
Simplify:
therefore, the equation of the quadratic is; f(x) =negative one sixteenthsx^2 − one half x + seven-fourths.
Answer:
y = 20 + 0.15x
where x = each minute of talk time
y = total cost
domain [0, ∞)
range [20, ∞)
Step-by-step explanation:
Your equation is like that because you always pay $20 per month, no matter how many minutes you used. Then you have 0.15 per minute so use x as a variable placeholder for the actual number of minutes.
domain is starting from 0 because you can't have negative minutes.
range is at least 20 because you pay $20 to use it even if you don't use any minutes. So it can't be less than $20.
Answer:
<em>26%</em>
Step-by-step explanation:
<em>In home run derby competition there were 32 home rinse hit out of 124 hits approximately</em>
A. Let x represent the number of miles and y represent the total price.
y=3x+15
B. Using the equation we just wrote, replace the x with 45.
y=3(45)+15
Now multiply 45 by 3.
y=135+15
And finally add together 135 and 15.
y=150
The total cost of a 45 mile taxi ride would be $150.00.
