8. The exponential function f takes the value 10 when x = 1 and 30 when x = 2.
a.) what is the y-intercept of f? Explain how you know
b.) what is an equation defining f?
Answers
Answer:
x = 2
Step-by-step explanation:
f(x) = x + 8
f(x) = 10
10 = x + 8
minus 8 from the both sides
10 - 8 = x
2 = x
x = 2
Hope this is right correct me if im wrong!!!
Exponential function is a function between the dependent variable and independent variable in which the constant change in the independent variable gives the same proportional change in the dependent variable.
a) y intercept of the function is 10/3. b) Equation defining function is,[tex]y=\dfrac{10}{3} \times 3^x[/tex]
Given information-
The exponential function [tex]f[/tex] takes the value 10 when,
[tex]x=1[/tex]
The exponential function [tex]f[/tex] takes the value 2 when,
[tex]x=2[/tex]
What is exponential function?Exponential function is a function between the dependent variable and independent variable in which the constant change in the independent variable gives the same proportional change in the dependent variable.
The general form of the exponential function,
[tex]y=ab^x[/tex]
Here [tex]a[/tex] is the y intercept of the function and exponent of independent variable [tex]x[/tex].
The exponential function [tex]f[/tex] takes the value 10 when the value of x is 1.
thus,
[tex]10=ab^1\\10=ab\\a=\dfrac{10}{b}[/tex]
Let the above equation as equation number 1.
The exponential function [tex]f[/tex] takes the value 2 when the value of x is 2,
[tex]30=ab^2\\30=ab^2\\a=\dfrac{30}{b^2}[/tex]
Compare the values of a,
[tex]\frac{10}{b} =\frac{30}{b^2}\\ b=\dfrac{30}{10}\\ b=3[/tex]
Put the value of b in equation 1,
[tex]a=\dfrac{10}{3}[/tex]
Thus the y intercept of the function is 10/3.
Put the values to find the equation,
[tex]y=\dfrac{10}{3} \times 3^x[/tex]
Hence,
a) y intercept of the function is 10/3. b) Equation defining function is,[tex]y=\dfrac{10}{3} \times 3^x[/tex]

Answer:
x = [tex]\frac{16}{3}[/tex]
Step-by-step explanation:
Since the triangles are similar then the corresponding sides are congruent.
EF and BC are corresponding sides , then
8x - 3 = 5x + 13 ( subtract 5x from both sides )
3x - 3 = 13 ( add 3 to both sides )
3x = 16 ( divide both sides by 3 )
x = [tex]\frac{16}{3}[/tex]

Geometry geometry geometry
Answers
Answer:
x = 1
Step-by-step explanation:
The proportion in this question is (3z) : (3z)+(z+22) = (2x+1) : (8x-2), since there are two triangles that are similar.
The question said that 3z = z+22
--> 2z = 22
--> z = 11
So our new proportion will be:
--> (3z) : (3z)+(z+22) = (2x+1) : (8x-2)
--> (33):(66) = (2x+1):(8x-2)
--> (66)(2x+1) = (33)(8x-2)
--> 132x + 66 = 264x - 66
--> 132x - 132 = 0
--> 132x = 132
--> x = 1

If the first step in the solution of the equation 2x - 8 = 5x + 3 is "subtract 2x," then what should the next step be?
subtract 5x
add 8
subtract 3
Answers
Answer:
You would not subtract 3...
Step-by-step explanation:
It should be
2x- 8= 5x+3
subtract 5x from both sides,
then add 8 onto both sides, then you would get 0 on one side, and 11 on the other so you would have
-3=11 which equals
3.6
Answer

Kevin drove for 4 hours and then stopped to eat dinner. The total distance he had driven at different time intervals is shown on the graph below.⬇️
• Using the information in the graph, determine Kevin’s average speed during these 4 hours.
• Kevin will drive for an additional 2 hours after dinner. He expects to drive 130 miles during these 2 hours, under the same driving conditions as the trip represented in the graph. Is this a reasonable expectation? Explain your answer and show your work.
Answers
Answer:
If you want a simple average, you can add all the speeds you see and divide them by the number of how many they are.
So firstly you have to calculate the speed of the first point, which is:
20 miles/0.5 hour
That means: 40 miles/hour
That would be your first "speed"
Then you calculate all of them :speed1+speed2+speed3 = something.
As an example: 20miles/hr + 40miles/hr+0miles/hr = 60miles/hr
Then, you divide it by how many "speeds" they are: 60miles/hr divided by 3 if I continue my previous example.
It is my first answer, and I hope I could help you a bit!
