What is a curve in a graph?A curve is defined as a smoothly- flowing continuous line that has bent. It does not have any sharp turns. The way to identify the curve is that the line bends and changes its direction at least once. Curve of the graph is a pictorial representation of a particular function.
Given : A object is thrown from the top of the building thus by observing the graph we derive the following information
1) Maximum height = 165 m
2) The object reaches maximum height at t=3 seconds
3) The time it took to reach the ground is 9 seconds
4) The building is 120 m tall
Hence, the answers are 1) 165 m 2)3 seconds 3) 9 seconds 4)120 m

create a situation relating to coins that can be modelled by the linear system and explain the meaning of each variable
x + y = 24
0.25x + 0.05y = 4.60
The situation involving coins that is modeled by the system of equations x + y = 24, 0.25x + 0.05y = 4.60 is given as follows:
You have a combination of 24 quarters and cents, and the total you have is of $4.60. How many coins of each type you have.
What is the system of equations?To obtain the meaning of each of the variables x and y, we look at the second equation, given as follows:
0.25x + 0.05y = 4.60.
This means that:
The variable x represents the total number of quarters, as each quarter coin is worth $0.25.The variable y represents the total number of nickels, as each nickel coin is worth $0.05.The result of this sum means that the total amount of money that you have is of $4.60.
The first equation is given as follows:
x + y = 24.
Which means that the total number of coins that you have is of 24.

Select all of the expressions that are equivalent to 109+ 29m − 49n.
2(5 + m − 2n)
9(10 + 2m + 4n)
29(5 + m − 2n)
2(−2n + m + 5)
9(−4n + 2m + 10)
−29(2n − m − 5)
The equivalent expressions of 10/9 + 2/9m − 4/9n are 2/9(5 + m - 2n) and -2/9(2n − m − 5)
How to determine the equivalent expressionsFrom the question, we have the following parameters that can be used in our computation:
109+ 29m − 49n
Express the expression properly
So, we have the following representation
10/9 + 2/9m − 4/9n
Factor out 2/9
So, we have
2/9(5 + m - 2n)
Factor out -1 from the expression
So, we have the following representation
-2/9(2n − m − 5)
Hence, the equivalent expression is -2/9(2n − m − 5)

A triangle is placed in a semicircle with a radius of 2 yd, as shown below. Find the area of the shaded region. Use the value 3.14 for pie, and do not round your answer. Be sure to include the correct unit in your answer.
Answer:
[tex]A_s=2.28yd^2[/tex]
Step-by-step explanation:
From the question we are told that:
Radius [tex]r=2yd[/tex]
Pie [tex]\pi=3.14[/tex]
Generally the equation for Area of the shaded part [tex](A_s)[/tex] is mathematically given by
[tex]A_s=Area\ of\ semi-circle(A_c)-Area\ of\ triangle(A_t)[/tex]
Generally the equation for Area of semi-circle is mathematically given by
[tex]A_c=\frac{1}{2}\pi r^2[/tex]
[tex]A_c=\frac{1}{2}*(3.14) (2)^2[/tex]
[tex]A_c=6.28yd^2[/tex]
Generally the equation for Area of triangle is mathematically given by
[tex]A_t=\frac{1}{2} base*height[/tex]
[tex]A_t=\frac{1}{2} (2+2)*2[/tex]
[tex]A_t=4yd^2[/tex]
Therefore Area of the shaded part [tex](A_s)[/tex]

What is 24.21 written in expanded form?
Answer:
(2 x 10) + (4 x 1) + (2 x 0.1) + (1 x 0.01)
Step-by-step explanation:
The expanded form of 24.21 = (20 + 4 + 0.2+ 0.01)
The expanded form of an equation requires writing out the place value term of each digit of the number given :
24.21 :
Tens digit = 2 × 10 = 20
Unit digit = 4 × 1 = 4
Tenth digit = 2 × 0.1 = 0.2
Hundredth digit = 1 × 0.01 = 0.01
Hence, the expanded form of the number is :
(20 + 4 + 0.2+ 0.01)

The volume of the pyramid shown is 16√3 cm³.
What is Volume?Volume of a three dimensional shape is the space occupied by the shape.
Given a solid oblique pyramid.
It has an equilateral triangle as a base with an edge length of 4√3 cm and an area of 12√3 cm².
Volume of the pyramid = 1/3 × base area × height
Base area = 12√3 cm²
Height = 4√3 × tan (30°) = 4√3 × 1/√3 = 4
Volume = 1/3 × 12√3 × 4
= 16√3 cm³
Hence the volume is 16√3 cm³.

The scale factor of the blueprint of a garage door to the actual garage door is 0.05. The area of the actual garage door is 220 ft2 . What is the area of the garage door on the blueprint
The area of the garage door on the blueprint is 0.55 ft^2.
The size of a patch on a surface is determined by its area. The area of an open surface or the boundary of a three-dimensional object is referred to as the surface area, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.
Given in question,
Scale factor = 0.05
Since this scale factor is for length.
The scale factor for the area = 0.05*0.05
= 0.0025
Original Area = 220
The area on the blueprint = 0.0025*220
= 0.55
Hence, the area of the garage door on the blueprint is 0.55 ft^2.

The function which has greater slope is Function 2.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
Function 1:
y = -2x + 10
and Function 2:
Slope = (5-10)/( 2-0) = -5/2
So, the Equation of line
(y - 10) = -5/2 (x -0)
y - 10 = -5/2x
y = -5/2x + 10
y= -2.5x +10
So, the slope of Function 1 is greater than slope of function 2.
