Answer:
s^2 = r^2 + h^2.
Step-by-step explanation:
You need to know the radius of the base as well.
Then you use the Pythagoras theorem:
s^2 = r^2 + h^2 where r = radius and h = the height.

Answer:
[tex]f^{-1}(x) = x/2 +2[/tex]
Step-by-step explanation:
let [tex]f^{-1} (x)[/tex] = y
then f(y) = x
2y-4 =x
2y =x+4
y= x/2 +2
hence f^{-1} (x) = x/2 +2
Use the Distance Formula to write an equation of the parabola with directrix y=7 and focus (0,−7).
Answer:
Step-by-step explanation:
Find the Parabola with Focus (7,0) and Directrix x=-7 (7,0) x=-7. (7,0) ( 7 , 0 ) x=−7 x = - 7. Since the directrix is horizontal, use the equation of a parabola that opens left or right. ... Find the distance from the focus to the vertex. ... Substitute in the known values for the variables into the equation (y−k)2=4p(x−h) ( y - k ) 2 = 4 p ...
Using the distance formula, the equation of a parabola with directrix y=7 and focus (0,−7) is [tex]x^2 = -28y[/tex]
The focus = (0, -7)
The directrix: y = 7
The distance formula is given as:
[tex](x - a)^2+(y-b)^2= r^2[/tex]
From the focus (0, -7)
a = 0, b = -7
r = y - 7
Substitute a = 0, b = -7 and r = y - 7 into the equation above:
[tex](x - 0)^2 + (y +7)^2 = (y - 7)^2\\\\x^2 + y^2+14y + 49= y^2-14y+49\\\\x^2 = y^2-y^2-14y-14y+49-49\\\\x^2 = -28y[/tex]
Using the distance formula, the equation of a parabola with directrix y=7 and focus (0,−7) is [tex]x^2 = -28y[/tex]

Answer:

23/14
=1.643
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
-11-(7*(1-2*f)+5)=0
-11 - (7 • (1 - 2f) + 5) = 0
14f - 23 = 0
3.1 Solve : 14f-23 = 0
Add 23 to both sides of the equation :
14f = 23
Divide both sides of the equation by 14:
f = 23/14 = 1.643
if a football is thrown upward, its height above the
ground is given by the equation s=-16t^2+Vot+so, where
Vo and so are the initial velocity and intial height of the
Football, respectively, and t is the time in seconds.suppose
the football is thrown from the top of a building that is
192 feet tall, with an initiae speed of 96 feet per second.
a)write the polynomial that gives the height of the Football in terms
of the variable t (time)
b) what is the height of the Football after 2 seconds have
Clapsed? Will the football hit the ground after 2 seconds?
Answer:
a) s = -16[tex]t^{2}[/tex] + 192t + 96
b) Height of the football after 2 seconds is 448 feet.
ii. The football would not hit the ground after 2 seconds.
Step-by-step explanation:
Given:
s = -16[tex]t^{2}[/tex] + [tex]V_{o}[/tex]t + [tex]s_{o}[/tex]
where: s is the height of the football above the ground, t is the time, [tex]V_{o}[/tex] is the initial velocity and [tex]s_{o}[/tex] is the initial height.
The height of the building = [tex]V_{o}[/tex] = 192 feet and the initial speed of the ball = [tex]s_{o}[/tex] = 96 feet per second, then;
s = -16[tex]t^{2}[/tex] + 192t + 96
a) The polynomial is given as:
s = -16[tex]t^{2}[/tex] + 192t + 96
b) The height of the football when t = 2 seconds is;
s = -16(2) + 192(2) + 96
= -32 + 384 + 96
= -32 + 480
s = 448
The height of the football when t = 2 seconds is 448 feet.
ii. The football would not hit the ground after 2 seconds.

66.6%
Guys I need help I’m gonna fail math
Answer:
125% correct
3/5 correct
2/3 correct
Step-by-step explanation:
Here, we want to pick the appropriate conversion from percentage to fraction:
To convert from percentage to fraction, we simply divide by 100
125% = 125/100 = 1.25 correct
30% = 30/100 = 0.3 not 0.03 wrong
1% = 1/100 = 0.01 not 0.001 wrong
60% = 60/100 = 3/5 correct
50% = 50/100 = 1/2 not 1/4 wrong
2/3 = 2/3 * 100 = 200/3 = 66.66667% correct

Is correct that is rounded to 30 BRAINLY PLS HELP ME OUT I FORGIT HOW TO DO THIS ASP !PLS !
Answer:
No, it doesn't.
Step-by-step explanation:
Whenever there's a "th" at the end of a mathematical word, it means decimal place. A tenth is the first number in a decimal. Ex. (Underlined is the tenth) 1.27. If you round them to the tenth, you would get 20 and 30. Therefore 20 does not round to 30 if rounding to the tenths.
Answer:
It would actually be 20.
Step-by-step explanation:
When rounding to the nearest tenth, you need to pay attention to the second-to-last digit in the number. If the number is anything from 0 - 4 it rounds down. If the number is anything from 5 - 9, it rounds up.

Can someone plz help me with this????
Answer:
since we cant see what info is given maybe these tips can help...
the 'b' is also called the y-intercept, the y-int is what you start of with. Example, if your parents give you $20 and you spend $5 every week, your y-int is 20
The m is the slope, so if your parents give you $20 and you spend $5 every week, your slope is -5 because your money is decreasing at a linear rate
the x is the input, so if you want to know how much money you have 2 weeks after you got $20, you would substitute x with 2, and solve to get $10
Students plan to pay back half the debt now though fundraising, and the rest after the harvest. Write an equation to represent the debt they will repay through fundraising. Use a negative integer to show debt. Use "D" to represent the debt that will be repaid by through fundraising.
Answer:
D = [tex]\frac{-d}{-2}[/tex]
Step-by-step explanation:
The students in this question are trying to pay back only half of the current debt (d) with the fundraiser (D). Since debt is money that is owed it would therefore be represented as a negative but in this case the fundraiser needs to be positive since it is money gained. So since we have a negative we would need to divide by -2 in order for the total to be positive.
D = [tex]\frac{-d}{-2}[/tex]
Finally, we are left with this equation which shows the debt that will be repaid through the fundraiser

Answer:
4 2/3 cups of water
Step-by-step explanation:
The original recipe has 3 1/2 cups of potatoes and 3 1/4 cups of water.
4.
If you put 5 cups of potatoes, you can find the amount of water you need using a proportion.
3 1/2 cups of potatoes is to 3 1/4 cups of water as 5 cups of of potatoes is to x cups of water.
(3 1/2) / (3 1/4) = 5/x
(7/2) / (13/4) = 5/x
7/2 * x = 13/4 * 5
2/7 * 7/2 * x = 2/7 * 13/4 * 5
x = 130/28
x = 65/14
x = 4 9/14
4 9/14 as a decimal is 4.64 which is close to 4.6666...
