Answer:
[tex]\bold{y=1.5\times 2^x+4}[/tex]
Step-by-step explanation:
Given:
Exponential function with common ratio 2.
Horizontal asymptote at y = 4
Passes through point (2, 10)
To find:
Equation of the exponential function ?
Solution:
Equation for an exponential function may be given as:
[tex]y=ab^x+c[/tex]
Where b is the common ratio and
c is the y value of horizontal asymptote.
[tex](x, y)[/tex] are the points on the function.
We are given that:
b = 2
c = 4
Let us put all the given values and find equation.
[tex]y=a\times 2^x+4[/tex]
Now, let us put [tex]x = 2, y = 10[/tex] to find the value of a.
[tex]10=a\times 2^2+4\\\Rightarrow a\times 2^2=10-4\\\Rightarrow a\times 4=6\\\Rightarrow a =1.5[/tex]
[tex]\therefore[/tex] the equation of exponential function is:
[tex]\bold{y=1.5\times 2^x+4}[/tex]
Find the midpoint of the line segment between the points
(2,5) and (-4, 9).
Answer:
The midpoint is (-1,7)
Step-by-step explanation:
To find the midpoint
Add the x terms together and divide by 2 to get the x coordinate
(2+-4)/2 = -2/2 =-1
Add the y terms together and divide by 2 to get the y coordinate
(5+9)/2 = 14/2 =7
The midpoint is (-1,7)

5x = 20 [÷6] Show the result of applying the given operations to both sides of these equations.
Answer:
x=⅔
Step-by-step explanation:
5x=20/6. multiply both sides by 6 to remove the denominator
5x(×6)= 20×6
6
30x=20
divide both sides by 30 to obtain the value of x
30x=20/30
30
x=20/30
x=⅔
A is directly proportional to x and inversely proportional to y. If A=20 when x=6 and y=9, what is the value of A when x=9 and y=6?
A) 1/20
B) 30
C) 45
D) 60
A=45
A=kx/y
where k is constant
substituting the values for k
k= 20×9/6=30
when x=9, y=6
A= 30×9/6=45

Answer:
It represents a linear function because there is a constant rate of change.
Step-by-step explanation:
A linear function is arranged in or extending along a straight or nearly straight line.
So if the numbers keeps increasing, which it is, it will be rising in an almost complete straight line on a graph. That means it is a linear function because the numbers keep increasing.

Type in the correct answer. What is the slope of line m? On a coordinate plane, a straight line goes through (negative 2, 1), (0, 0), and (2, negative 1).
Answer:
-0.5 or -1/2
Step-by-step explanation:
The equation for slope is y₂-y₁ / x₂-x₁.
It should work with all of the points given. Any of the 2 points you choose will give you the slope -0.5 or -1/2.
The slope the straight line going through (-2,1) , (0,0) and (2,-1) is -1/2.
What is a line segment?A line section that can connect two places is referred to as a segment.
In other words, a line segment is just part of a big line that is straight and going unlimited in both directions.
The line is here! It extends endlessly in both directions and has no beginning or conclusion.
The average slope of a straight line ;
The slope associated with two points (x₁, y₁) and (x₂, y₂) is given by
Slope = (y₂ - y₁)/(x₂ - x₁)
So slope associated with two points (-2,1) , (0,0)
⇒ (0 - 1) / (0 + 2)
⇒ -1/2
Since all three points are in a straight line so slope must be the same.
Hence "The slope the straight line going through (-2,1) , (0,0) and (2,-1) is -1/2".

Given:
3 batches of brownies from 3/2 cups of chocolate left.
Step-by-step explanation:
From the question, we know that:
1/2 cups of chocolate = 1 batch of brownies
3/2 cups of chocolate = x
Cross Multiply
1/2 × x = 3/2
x = 3/2/1/2
x = 3/2 × 2/1
x = 3 batches.
That means she can make 3 more
3+1=4
Therefore, the batches of brownies can Luisa make is 4 batches.

Answer:
The table represents a proportional relationship
Step-by-step explanation:
Given
x ------ y
1 ------- 15
2 --------30
4 ---------60
5 -------- 75
Required
Determine if the table shows a proportional relationship
To check this, we make use of the following formula;
[tex]k = \frac{y}{x}[/tex]
Where k is the proportionality constant
When x = 1, y = 15
[tex]k = \frac{15}{1} = 15[/tex]
When x = 2, y = 30
[tex]k = \frac{30}{2} = 15[/tex]
When x = 4, y = 60
[tex]k = \frac{60}{4} = 15[/tex]
When x = 5, y = 75
[tex]k = \frac{75}{5} = 15[/tex]
Since the value of k for all values of x and y is the same; i.e. 15
Then, the table represents a proportional relationship

The expression 100 + 20m100+20m100, plus, 20, m gives the volume of water in Eduardo's pool (in liters) after Eduardo spends mmm minutes filling his pool. What is the volume of water in Eduardo's pool after he fills it for 5 \dfrac145 4 1 5, start fraction, 1, divided by, 4, end fraction minutes?
Answer:
205 litres
Step-by-step explanation:
Given:
Volume of water is given as:
[tex]V=100+20m[/tex] (in litres)
m is the time in minutes spent filling water in Eduardo's pool.
To find:
Volume of water in the pool after the water is filled for [tex]5\frac{1}{4}[/tex] minutes.
Solution:
Here, volume of water in the Pool (in litres) is given by the equation:
[tex]V=100+20m[/tex] ....... (1)
Where m is the time for which Eduardo fills the pool.
Here, we are also given that
m = [tex]5\frac{1}{4}[/tex] minutes = [tex]\frac{5\times4+1 }{4}=\frac{20+1}{4}=\frac{21}{4}[/tex] minutes
And we have to find the value of V after [tex]\frac{21}{4}[/tex] minutes.
Let us put the value of m as [tex]\frac{21}{4}[/tex] minutes in the equation (1) to find the value of V.
[tex]V=100+20m\\\Rightarrow V = 100 + 20 \times \frac{21}{4}\\\Rightarrow V = 100+105\\\Rightarrow \bold{V = 205\ litres}[/tex]
So, the volume of water in the pool after [tex]\frac{21}{4}[/tex] minutes is 205 litres.

Asia contains both the highest and lowest known points on earth. Mt. Everest is a little over 29,000 feet above sea level, and the shore of the Dead Sea is about 1,370 feet below sea level. What is the approximate difference in elevation between the two points?
27,630 feet
28,370 feet
29,370 feet
30,370 feet
Answer:
30,370 feet
Step-by-step explanation:
The difference in elevations between two points will be 30370 feet.
It is given that Mt. Everest is 29000 feet above sea level and the shore of dead sea is 1370 feet below the sea level.
We have to find out the difference in elevation between the two points.
What is algebra ?
Algebra is the branch that deals with various symbols and the arithmetic operations such as addition , subtraction , etc.
As per the question ;
Height of Mt. Everest from sea level = 29000 ft. above
Height of shore of dead sea from sea level = 1370 feet below
As these both are in opposite directions , i.e., one above sea level and other below sea level , we should add both of these to find the difference in elevations between these two points.
i.e.,
The difference in elevations between two points will be ;
= 29000 + 1370
= 30370 feet
Thus , the difference in elevations between two points will be 30370 feet.
