Number 1= 26.2 i hope this helps
Answer:
Step-by-step explanation:
The given solid is a square based pyramid. The formula for determining the volume of a square based pyramid is
Volume of pyramid = 1/3 × A×H
Where
A represents the area of the square.
H represents the height from the base to the apex of the pyramid.
Area of the square base is expressed as length × length
The length of the square base is 5 ft
Area of the square base is 5×5 = 25ft^2
Volume of the is 1/3 × 25× 7 = 58.33
Approximately 58.3 ft^3
Answer:
Step-by-step explanation:
As we move from the x-intercept (-2, 0) to the y-intercept (0, 4), x increases by 2 (this is the run) and y by 4 (this is the rise). Thus, the slope of this line is
m = rise/run = 4/2 = 2.
Given the y-intercept (0, 4) and the slope (2), the slope-intercept form of the equation of this line is y = 2x + 4.
From this we get the point-slope form:
y = 2x + 4 becomes y - 4 = 2(x - 0), or just y - 4 = 2x.
Answer:
--- equation
--- focus
--- directrix
---- focal width
Step-by-step explanation:
Given
Required
The equation of parabola
The depth represents the y-axis. So:
The diameter represents how the parabola is evenly distributed across the x-axis.
We have:
-2 to 2 is 4 units.
So:
![x = [-2,2]](https://tex.z-dn.net/?f=x%20%3D%20%5B-2%2C2%5D)
So, the coordinates of the parabola is:
The equation of the parabola is calculated using:
Substitute (-2,2) for (x,y)
Divide by 8
So, the equation is:
The defining features
<u>(a) Focus</u>
The focus is located at:
<u>(b) Directrix (y)</u>
<u>(c) Focal width</u>
Answer:
5.5?
Step-by-step explanation:
Honestly, I think it's just because the 4 pack of the 5.5 will equal more than the others tbh. Might be wrong, But I believe it's 5.5.
