The graph of an exponential function has a y-intercept of 8 and contains the point (3,64). Find the exponential function that describes the graph.
Given:
Y-intercept of exponential function is 8.
It contains the point (3,64).
To find:
The exponential function that describes the graph.
Solution:
The general form of an exponential function is
[tex]y=ab^x[/tex] ...(i)
where, a is initial value or y-intercept and b is growth factor.
Since, y-intercept is 8, therefore, a=8.
Put a=8 in (i).
[tex]y=8b^x[/tex] ...(ii)
It contains the point (3,64). Put x=3 and y=64.
[tex]64=8b^3[/tex]
Divide both sides by 8.
[tex]\dfrac{64}{8}=b^3[/tex]
[tex]8=b^3[/tex]
[tex]2^3=b^3[/tex]
On comparing both sides, we get
[tex]b=2[/tex]
Put b=2 in (ii).
[tex]y=8(2)^x[/tex]
The functions form of this equation is
[tex]f(x)=8(2)^x[/tex]
Therefore, the required function is [tex]f(x)=8(2)^x[/tex].

Answer these two questions I am confused. Number 17 and 18.
Answer:
Step-by-step explanation:
Question 17
y-y1 = m (x-x1 )
so basically you plug in the (x,y) to y1 and x1 place
Remeber always times it by -1
so answer would be
y-2 = -1/3 (x+4)
Question 18
Pretend its 3x+2y =8
you need to find x or y first im going to find y first
so
- 2y = -3x +8
divide by 2 to isolate y
y = -3/2x - 4
plug it back into the equation
3x + 2(-3/2x) - 4
the x will cancel
so y= -4
Then
plug in the -4 in place of y
SO the Answer is YES because y is horizontal there is -4 = there will be (-3, -4)!
Kyle asked a random group of students what their favorite sport was. The results are below. Boys Girls Basketball 10 8 Football 25 7 Soccer 9 19 Baseball 18 22 If Kyle were to randomly select a girl to explain why she likes the sport chosen, what is the probability that he will pick a girl who likes football? A 12.5% B 27.1% C 40.3% D 44.6%
Answer:
The probability that Kyle will pick a girl who likes football is 12.5%.
Step-by-step explanation:
The data provided is as follows:
Boys Girls Total
Basketball 10 8 18
Football 25 7 32
Soccer 9 19 28
Baseball 18 22 40
Total 62 56 118
Compute the probability that Kyle will pick a girl who likes football as follows:
[tex]P(F|G)=\frac{n(G\cap F)}{n(G)}[/tex]
[tex]=\frac{7}{56}\\\\=0.125\\\\=12.5\%[/tex]
Thus, the probability that Kyle will pick a girl who likes football is 12.5%.

A). Interval A and B
B).interval D and F
C).interval C and E
D).interval A,B,C and E
Option A is the correct answer; i.e. interval A and B.
What is Distance?The distance between two points is the length of the path connecting them.
Here, from the given graph, we can conclude that
A and B show the distance Increasing, the line is going up so as time has passed he is getting far to his house. Continuously 1 hour 45 mins he increases hi distance without staying anywhere.

the volume of a cube is 125m find it's side
Answer:
41.6666666667m ( round to nearest whole number if you need to) -> 42m
Step-by-step explanation:
To find the volume
You multiply the length, width, and height. ( V= LxWxH)
So, divide 125 by 3 and you get 41.6666666667.
To check your answer: 41.6666666667 times 3 and you get 125.

((I'LL GIVE BRAINIEST))Write an expression for the perimeter of the triangle shown below: (4 points)
A triangle is shown with side lengths labeled 0.5x plus 9, 3x, and negative 3.4x minus 25.
a
6.9x − 16
b
6.9x + 16
c
0.1x − 16
d
0.1x + 16
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
Perimeter = Sum of the sides
Thus ;
[tex]Perimeter = (0.5x + 9) + ( 3x) + ( - 3.4x - 25) \\ [/tex]
[tex]Perimeter = - 3.4x + 3x + 0.5x - 25 + 9 \\ [/tex]
Collect like terms
[tex]Perimeter = 0.1x - 16[/tex]
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
Thus the correct answer is (( c )) .
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
Answer:
perimeter = A + B + C
perimeter = 0.5x + 9 + 3x + (-3.4x - 25)
perimeter = 0.5x + 3x -3.4x + 9 - 25
perimeter = 3.5x - 3.4x + 9 - 25
perimeter = 0.1x + 9 - 25
perimeter = 0.1x - 16
Simpfly: 9f + 10f - 12f
Answer:
7f
Step-by-step explanation:
Just add them all together keeping the f on
Then subtract keeping the f on
Answer:
7f
Step-by-step explanation:
To simplify you will need to do it the same way as in adding natural numbers the variable doesn't change the number
So it's going to be;
9f+10f-12f
(Nine plus Ten is equal to 19)
•The variable remains the same
19f-12f
•So you subtract 12 from 19 which is going to be;
7f
-2-(x-3)=-4
What does x equal?
Answer:
x = 5
Step-by-step explanation:
-2 -(x-3) = -4
You have to switch the signs into their opposites when you have -(?)
-2 - x + 3 = -4 Add liked terms
-x + 1 = -4
- 1 - 1 Subtract 1 from both sides
-x = -5 Get rid of the negative in the x
/-1 /-1 Divide -1 from each sides
x = 5
