Fredrick threw a ball from the top of a building. The height of the ball, in feet, after it is thrown is modeled by the function
h() = -1612 + 641 + 100, where i represents time, in seconds.
Answer:
5.2 secondsStep-by-step explanation:
GivenThe function h(t) = -16t^2 +64t + 100To find: Time the ball to reach the ground (h = 0)? Solutionh(t) = -16t^2 +64t + 100Need to find the value of t, when h(t) = 0
-16t^2 +64t + 100 = 04t^2 - 16t - 25 = 04t^2 - 2*2t*4 + 16 = 41(2t - 4)^2 = 412t - 4 = √412t - 4 = 6.42t = 10.4t = 5.2Answer is 5.2 seconds

In geometry a
is a location. It has no size. It is
represented by a dot.
Points play a crucial role in defining distances, angles, and relationships between different geometric objects, providing a foundation for the study of geometry.
In geometry, a point is a fundamental concept that represents a precise location in space. It is a basic building block from which geometric figures and shapes are constructed. A point has no size, shape, or dimensions. It is often denoted by a dot or a small letter, such as point A (A). Points are used to describe the positions of other geometric elements, such as lines, curves, and polygons. They serve as reference markers and can be connected to form line segments and rays.

Jamine has a half-sheet cake. If she has six friends, how much will each one get?
Answer:
1 12th (1 over 12)
Step-by-step explanation:
If she had a whole cake it would be 1 6th (1 over 6) of the cake. To get the answer for this do fraction for the amount of food then multiply that by 1 as the numerator and the number of people as the denominator (1 over the # of people). Then the fraction you get as your answer from multiplying that is the fraction or answer to your question. Note this only works with these types of questions. I really hope this helps.

Step-by-step explanation:
Use the figure below to find the value of y and each angle shown.
5y - 16 + 3y + 20 = 180 degrees
Combine like terms on the left side
8y + 4 = 180
Subtract 4 from both sides.
8y = 176
Divide both sides by 8
y = 22
Plug 22 into y for each angle.
3y + 20 = 3(22) + 20 = 66 + 20 = 86 degrees
5y - 16 = 5(22) - 16 = 110 - 16 = 94
The angle opposite 5y - 16 also equals 94 because they are vertical angles.
The angle opposite of 3y + 20 also equals 86 because they are vertical angles
Given that f(x) = 5x^2-3x+7 and f(g(x))=(5x^4)/9 + (17x^2)/3 + 21. Find all possible values for the sum of the coefficients in the quadratic function g(x).
steps
(x) = 5x^2-3x+7
refine
x=5x^2-3x+7
Switch sides
5x^2-3x+7-x=x-x
Subtract x from both sides
5x^2-4x+7=0
Solve with the quadratic formula

The scale drawing of a rectangular city park measures 10.0 cm by 5.0 cm. The scale of the drawing is 1.0 cm = 4.5 m. What is the area, in square meters, of the park?
Answer:
2250m^2Step-by-step explanation:
In this exercise, we are going to be converting from cm to m, since we are asked to provide our answers in meters
Given that the scale is 1.0 cm = 4.5 m
let us convert the 10cm to the actual length
1 cm------4.5m
10 cm------x
x= 4.5*10
x= 45m
Also for the 5 cm
1 cm------4.5m
5 cm------x
x= 5*10
x= 50m
Hence the area of the actual rectangular park is
45*50= 2250m^2

Answer:
-450
Step-by-step explanation:
The value of factors of the function are,
⇒ 5 (9x - 2)
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;
The expression is,
⇒ 45x - 10
Now, We can factor the equation as;
⇒ 45x - 10
⇒ 5×9x - 5×2
⇒ 5 (9x - 2)
Thus, The value of factors of the function are,
⇒ 5 (9x - 2)
