Answer:
-120
Step-by-step explanation:
1-121 =
121 - 1 = 120
It becomes a negative because 1 is less than 121
A soccer ball is kicked from the ground with an initial upward velocity of 64 meters per second, and the height of the ball can be represented by the equation h = -16t^2 + 64t. After how many seconds will the ball hit the ground?
Answer:
t = 2 seconds
Step-by-step explanation:
Given that,
h = -16[tex]t^{2}[/tex] + 64 t
where h and t have their usual meaning.
To determine the number of seconds required of the ball to hit the ground, differentiate the given equation with respect to t.
0 = -32 + 64
So that,
32t = 64
t = [tex]\frac{64}{32}[/tex]
t = 2
The ball will hit the ground in 2 seconds.
What is the Volume of the hemisphere ? I will give BRAINLIEST
Answer:
8579 mm^3
Step-by-step explanation:
The formula for the volume of a sphere is V = (4/3)(pi)(r)^3, where r is the radius.
Here the radius is (appears to be) 16 mm.
Thus, the radius of this sphere is V = (4/3)(pi)(16 mm)^3, or 28268 mm^3.
But we want the volume of the hemisphere (half sphere). Thus,
divide the above result by 2:
The volume of this hemisphere is 8579 mm^3
Answer:
8.582
Step-by-step explanation:
volume of hemisphere is 2 / 3 π r^3
2/3 πr^3
π is 22/7
r is 1.6 mm
2/3 × 22/7 × 1.6^3 = 8.582 to 3 decimal places

Essay on how to use math outside of school?
Answer:
Mathematics is everywhere and is used by everyone, even a basic form of it. Some jobs require just simple maths, some require advanced maths. There are many uses of it from business to culinary. Simply counting is doing maths. Retracing back or adding time is doing maths. Mathematics is used to build cars to buildings. It is inevitable that you will be using maths any time now.

A parabola can be drawn given a focus of (1, 10) and a directrix of
y = 4. What can be said about the parabola?
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).

There are 86,400, frames of animation in 1 hour of anime. How many frames are there per second? There are 3,600 seconds in 1 hour.
Answer:
24
Step-by-step explanation:
Since there are 3,600 seconds in 1 hour, there are 3,600 times fewer fracmes in a second than in 1 hour.
86,400/3,600 = 24

Which graph does not represent a function
Answer:
The graph that does not represent a function is;
The first graph of the circle
Step-by-step explanation:
A function is a relationship, rule or law that maps the inputs 'x' the input set 'X' known as the domain, to exactly one output 'y' in the output set 'Y' known as the range
Therefore, a function maps an input to exactly one output
In a graph, the inputs are usually the x-variables, therefore the graph that maps the x-variables (in which an x-variable has) to more than one y-variable is the graph of the circle
In the graph of the circle, we have;
When x = 0 at the origin, y = 0
Similarly
When x = 0 at the maximum point, y = 4
Therefore, the graph of the circle does not represent a function.

Step-by-step explanation:
The hypotenuse is the longest side of a triangle.
You could either add a point at (3,2) or (6,9) to make a right triangle and get the same answer, but for the sake of looking at it right-side-up, I'd use (3,2).
Now, you can use the distance vertically (y coordinate) from the top point to the bottom point ( 9 to 2 ) as your first side length. 9-2= 7, so 7 is that side length.
Then, you can use the distance horizontally (x coordinate) from the bottom left point (3,2) to the bottom right point (6,2). 6-3= 3, so 3 is that side length.
Now for the Pythagorean Theorem (a^2 + b^2 =c^2)
7^2 + 3^2 = c^2
49+9=c^2
58=c^2
c= [tex]\sqrt{58\\\\}[/tex] is the distance between points

Find the value of a from given figure.
Answer:
45°
Step-by-step explanation:
three angles in a triangle sum up to 180
90° + a + a = 180°
90° + 2a = 180°
2a = 180°-90°
2a = 90°
a = 45°

You decide that you want to make a lighter purple paint. You make the new mixture by adding 1/4 cup of white paint for every 1/4 cup of red paint and 1/2 cup of blue paint. How much red paint, blue paint, and white paint do you use to make 1 1/2 gallons of the lighter purple paint?
Answer:
Cups of white paint = 24 * 1/4 = 6 cups
Cups of red paint = 24 * 1/4 = 6 cups
Cups of blue paint = 24 * 1/2 = 12 cups
Step-by-step explanation:
1/4 cup of white paint is added for every :
1/4 cup of red paint and 1/2 cup of blue paint :
1 gallon = 16 cups
1 1/2 gallons = 16 + 8 = 24 cups
To make 1 cup of lighter purple paint ;
1/4 cup of white + 1/4 cup of red + 1/2 cup of blue
Therefore ;
To make 24 cups of lighter purple paint :
Cups of white paint = 24 * 1/4 = 6 cups
Cups of red paint = 24 * 1/4 = 6 cups
Cups of blue paint = 24 * 1/2 = 12 cups
