Step-by-step explanation:
Identify the range of the function y=-3x+6 when the domain is {-1,2,4}
A. {-6,0,9}
B. {-9}
C. {3,-12,-18}
D. {-3,12}
E. {-6,9}
Answer:
A. {-6,0,9} but in order of domain it's {9,0,-6}
Step-by-step explanation:
There's two ways of finding the range;
Way #1: The traditional method
In the traditional method you substitute x for all the numbers in the domain When substituting you replace x and solve it like a regular equation (so for example for -3(-1) + 6 = 9 so y=9 when x equals to 2 or f(-1)= 9) to find yAfter substituting your y-values or the range (in order from least to greatest in domain or x-values) is {9,0,-6}Way #2: The graphing calculator method
Using a graphing calculator you use the table function Turn on the calculator press the button "Y=" place the function -3x+6 Hit "2nd" then "Graph" to get the tableLook at your x-functions to find your domain and next to these domains are your y-values those y-values that correlate to your domain are the ranges which are {9,0,-6}Muse synthetic division to find the quotient and remainder when 3x^4 +19x^3+22x^2-6x+4 is divided by x+2

Answer:
10 OR 100. Read the explanation for details.
Step-by-step explanation:
If Martin scored 10%, and this represents 10 points, that means that martin scored 10 points. If he is talking about ALL the points in total then there are 100 points because 10% is 1/10, and if each 1/10th is 10 points, if you multiply that by 10 you get

Find a quadratic function that includes the set of values below
(0,8) (2,10) (3,1)
The quadratic function is defined as follows:
- 2 / 3 x² + 7 / 3 x + 8
How to find quadratic function?The quadratic function has the following sets of values below:
(0,8) (2,10) (3,1).
The quadratic function is represented as follows:
f(x) = ax² + bx + c
using (0,8)
8 = a(0)² + b(0) + c
8 = c
Therefore, using (2, 10)(3 , 1).
f(x) = ax² + bx + c
10 = a(2)² + b(2) + 8
10 - 8 = 4a + 2b
2 = 4a + 2b
1 = 2a + b
1 = a(3)² + b(3) + 8
1 = 9a + 3b
Hence, combine the equations,
2a + b = 1
9a + 3b = 1
multiply equation(i) by 3
6a + 3b = 3
9a + 3b = 1
3a = - 2
a = - 2 / 3
Therefore,
9a + 3b = 1
9(- 2 / 3) + 3b = 1
-6 + 3b = 1
3b = 7
b = 7 / 3
Therefore, the quadratic function is defined as follows:
- 2 / 3 x² + 7 / 3 x + 8

The points G and H, 19m apart are on the same side of a tree. The angles of elevation of the top T, of the tree from G and H on the horizontal ground with the foot of the tree are 430 and 38° respectively. (1). Illustrate the information in a diagram. (i). Find, correct to one decimal place, the height of the tree.
Using relations in a right triangle, it is found that
The height of the tree is of 91.6 meters.
The graph for this problem is given at the end of the answer.
What are the relations in a right triangle?The relations in a right triangle are given as follows:
The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.From the diagram graphed, we can build two relations involving the tangent of the angles, as follows:
From the smaller right triangle:
tan(43º) = h/x
0.9325 = h/x
x = (1/0.9325)h.
x = 1.0724h (we want to find h, hence we write x as a function of h).
From the larger right triangle:
tan(38º) = h/(x + 19).
tan(38º) = h/(1.0724h + 19).
0.7813 = h/(1.0724h + 19).
Applying cross multiplication:
h = 0.7813(1.0724h + 19).
h = 0.8379h + 14.8447.
0.1621h = 14.8447
h = 14.8447/0.1621
h = 91.6 meters.

The world's supply of helium is finite. There are approximately 35 billion cubic meters of helium on Earth, and every year humans consume about 210 million cubic meters of it. Let stand for the volume (in millions of cubic meters) of helium remaining, and stand for the number of years since 2018. Which of the following linear equations could model the decreasing supply of helium
The equation which correctly models the decreasing supply of helium as described in the task content is; y = 35 - 0.21x.
Which equation correct models the decreasing supply of helium?It follows from the task content that the equation which correctly models the decreasing supply of helium according to the description is to be determined.
Let, y = amount of helium remaining.
Let x = no of years since 2018.
First, one must convert 210 million to billion cubic feets as follows;
210 million = (210/1000) billion.
= 0.21 billion cubic meters per year.
The number above represents the rate of change of the linear model, otherwise termed the slope.
On this note, since the starting deposit of helium in 2018 was; 35 billion.
This insinuates that the y-coordinate of the y-intercept of the required model is; 35.
Hence, the required decreasing Linear model for the supply of helium is;
y = 35 - 0.21x.
The equation above follows from the slope-intercept form of a linear equation.

x + 3 = 0
subtract 3 on both sides
x = -3
x +4 = -3
subtract 4 on both sides
x = -7
3x = 0
divide 3 on both sides
x = 0
5x = 2
divide 5 on both sides
x = 2/5
x - 4 = 0
add 4 on both sides
x = 4
5x - 4 = 0
add 4 on both sides then divide both sides by 5
x = 4/5
2x + 4 = 5
subtract both sides by 4 then divide both sides by 2
x = 1/2
2x^2 = 9
square root both sides then divide both sides by 2
x = 3/2
5x - 1 = 2
add both sides by 1 then divide both sides by 5

water are wasted each day?
[3 marks]
Answer: 108 liters
Step-by-step explanation: There are 86,400 seconds in a 24-hour day. If 25 mL leak every 20 seconds, divide 86,400 by 20 (4,320), then multiply by 25 (108,000). There is 1,000 mL for every liter, so divide 108,000 by 1,000, and you will get 108 liters.
