Answer:
The graph of g(x) has a lesser y intercept
Step-by-step explanation:
Given
f(x) = 100(-x + 4)
Required
Determine the relationship between f(x) and g(x)
First, we need to get the equation of g(x).
From the question, we have that:
Initial Value = 360
Rate = -90 yearly
[It is negative because the rate shows decrement]
Hence, the equation of g(x) is:
g(x) = Initial Value + Rate * x
Where x represents number of years
g(x) = 360 + (-90 * x)
g(x) = 360 - 90x
g(x) = -90x + 360
Recall that
f(x) = 100(-x + 4)
f(x) = -100x + 400
To solve y intercept, we set x = 0.
f(0) = -100 * 0 + 400 = 0 + 400 = 400
g(0) = -90 * 0 + 360 = 0 + 360 = 360
By comparison, the graph of g(x) has a lesser y intercept
To solve x intercept, we set y = 0
For f(x)
0 = -100x + 400
100x = 400
x = 4
For g(x)
0 = -90x + 360
90x = 360
x = 4
By comparison, they have the same x intercepts.

The points that lie on the given line are the solution of the line.
What is an equation of a line?The equation y = mx + c is the general equation of any straight line where m is the gradient of the line and c is the y -intercept.
Given is an equation of a line 2x+9y = 11, we need to find its solution,
Since, the line is an infinite object it carries an infinite solution too.
When we plot the graph of this line, all the points lying on it will be the solution of the line.
Let say x = 0,
2(0)+9y = 11
9y = 11
y = 11/9
Therefore, (0, 11/9) is the solution of the equation,
Let say x = 1
2(1) + 9y = 11
y = 1
Therefore, (1, 1) is the solution of the equation,
Please check the graph attached.
Hence, the points that lie on the given line are the solution of the line.

Answer:
y = 12.5
Step-by-step explanation:
Notice these are similar triangles since they have angles of the same measure (congruent angles), then there must be a proportion among their sides such that:
[tex]\frac{y+5}{5} =\frac{14}{4}[/tex]
therefore by cross-multiplying, we get:
4(y + 5) = 14 * 5
4 y + 20 = 70
4 y = 70 - 20
4 y = 50
y = 12.5

What is the circumference
Answer:
In geometry, the circumference is the perimeter of a circle or ellipse. That is, the circumference would be the arc length of the circle, as if it were opened up and straightened out to a line segment. More generally, the perimeter is the curve length around any closed figure.
Step-by-step explanation:
Answer:
1. Circumference = 87.92
2.Circumference = 43.96
Step-by-step explanation:
The first problem it had a radius. So in order to find the circumference you will have to use the formula 2πr. When you plug in the 14 yd in the radius spot it will look like 2π(14) when you solve it the answer will be 87.92
The second one has a diameter so the equation you will have to use is πd. Now you will have to plug the 14 cm where the diameter is which will look like π(14) when you solve it the answer will come out as 43.96

how do you find the area of a circle with only the height
Answer:
in geometry, a circle is the curve that forms the boundary of a disc. Curves, like lines, have zero width and thus zero area.
For some reason, this very simple thing doesn’t seem to be taught much - I certainly recall my maths teachers referring to the area of a circle instead of the area of a disc!
As you haven’t mentioned the radius of the circle, let us consider a generic circle of radius r, thus we want to find the height of a triangle whose area is πr².
Step-by-step explanation:
How is making a table of equivalent ratios to find the unit rate similar to finding the unit rate by calculating with fractions? Use a specific example to explain your reasoning.
Using specific examples, the unit rate can be obtained using equivalent ratio tables and fraction thus :
Table of equivalent ratios :
No of workers : ____ 2 ____ 4 ____ 6 ____ 8
Logs of wood cut: __ 4 ____ 8 ____12 ____16
To obtain the unit rate from the table :
Take the ratio of any pair of values ;
16/8 = 2 logs of wood
Hence, the unit rate is 2 logs of wood per worker.
Using the fractions :
2 worker = 4 logs of wood
1 worker = x
Cross multiply
2x = 4
x = 4/2
x = 2 logs of wood.
Hence, the unit rate is 2 logs of wood per worker.

In a survey, of the voters support a particular referendum. If 40 voters are chosen at random, find the mean and variance for the number of voters who support the referendum.
This question is incomplete, the complete question is;
In a survey, 55% of the voters support a particular referendum. If 40 voters are chosen at random,
find the mean and variance for the number of voters who support the referendum.
Answer:
a) The Mean is 22
b) Variance is 9.9
Step-by-step explanation:
Given that;
55% of the voters support a particular referendum p = 0.55
q = 1 - p = 1 - 0.55 = 0.45
sample size n = 40
a)
Mean = sample size n × p
Mean = 40 × 0.55
Mean = 22
Therefore the Mean is 22
b)
Variance = n × p × q
so we substitute
Variance = 40 × 0.55 × 0.45
Variance = 9.9
Therefore the Variance is 9.9
you should solve the answer for z not m pls
Step-by-step explanation:
we can factor out z
so that'll be
z((1/m)-(1/n))=1
divide by the value in parentheses on both sides
z=1/((1/m)-(1/n))
I can't tell if there's more the problem wants you to do. I could rewrite the equation on paper more easily, but I don't have one on hand
