Answer:
y = 2·2^x
Step-by-step explanation:
When the exponential function is of the form ...
y = a(b^x)
The value of 'a' is the value of y when x=0. The table tells us a = 2.
The value of 'b' is the ratio between values of y when their corresponding x-values differ by 1. The table tells us b = (4/2) = 2.
Then the exponential function describing the table is ...
y = 2(2^x)

What is the primary difference between exponential and linear functions?
A: The growth of an exponential function is proportional to the previous growth while the growth of a linear function is constant.
B:The growth of a linear function is proportional to the previous growth while the growth of an exponential
function is constant.
C:The growth of a linear function is proportional to the previous growth while the growth of an exponential
function is proportional to the quadratic growth.
D:The growth of an exponential function is proportional to the quadratic growth while the growth of a linear function is constant.
Answer:
A
Step-by-step explanation:
We know that the growth of a linear function will always be constant. So, that eliminates B and C.
A quadratic function can be a function such as [tex]x^2[/tex], or [tex]5x^2+7x[/tex], etc.
An exponential function wouldn't be [tex]x^2[/tex], it would be [tex]2^x[/tex]! Or [tex]3^x[/tex], or [tex](1.738283)^x[/tex], etc. Therefore, D is eliminated.
So, the answer is [tex]\boxed{A}[/tex] and we're done!
Sam bowled three games with scores of 210, 185, and 190. He needs to have a four-game average of 205 to qualify for an elite bowling league. What score does he have to bowl on the fourth game to have the average of 205 that he needs?
Answer: 235
Step-by-step explanation:
Total score if he average 205 = 205 * 4 = 820
Score needed on 4th game = 820 - 210 -185 - 190 = 235

Hey there,
Before solving the sum you have to know about the BODMAS theorem.
That means you have to solve this sum according to the BODMAS theory.
BODMAS theory is,
B - Brackets
O - Of
D - Division
M - Multiplication
A - Addition
S - Subtraction
Let us solve the sum now.
[tex]3 \times {2}^{3} + {5}^{2} - 18 \div 6 \\ 3 \times 8 + 25 - 18 \div 6 \\ 24 + 25 - 3 \\ 49 - 3 \\ = 46[/tex]

A submarine dives 51 3/5 meters below the surface of the water in 4 minutes. how many meters does the submarine dive each minute? NO LINKS!
A: 12 9/10
B: 12 3/4
C: 206 2/5
D: 47 3/5
Answer:
a
Step-by-step explanation:
51 3/5 = 258/5
258/5 / 4 = 12.9 (meters the submarine dives each min)
now we have to find out what 12.9 is as a fraction!
12.9= 12 9/10 because .9 is equal to 9/10, and 12. equals 12!

What is the value of x?
Enter your answer in the box.
Answer:
x = 50
Step-by-step explanation:
→ Make the equations equal to each other
2 ( x + 10 ) = 3x - 30
→ Expand brackets
2x + 20 = 3x - 30
→ Minus 3x from both sides
-x + 20 = -30
→ Minus 20 from both sides
-x = -50
Opposite angles are equal
[tex]\\ \sf\longmapsto 2(x+10)=3x-30[/tex]
[tex]\\ \sf\longmapsto 2x+20=3x-30[/tex]
[tex]\\ \sf\longmapsto 3x-2x=30+20[/tex]
[tex]\\ \sf\longmapsto x=50[/tex]

Which expression is equivalent to 6f-1+7f-8?
13f+7 5f-1
-f+7 or -9+13f
Answer:
Step-by-step explanation:
6f - 1 + 7f - 8 = 6f + 7f - 1 - 8
= 13f - 9
Combine like terms. Like terms have same variable with same power.
Answer:
-9+13f
Step-by-step explanation:
6f+7f = 13f
-1 + -8= -9
So the sum of them is -9+13f

Answer:
Its 26.2
Step-by-step explanation:

Answer:
The answer is 26.2
Step-by-step explanation:
I took this test, got it wrong, then it explained it so that I could completely understand the question.
Set the mean and standard deviation to 0 and 5 , respectively. Approximately 5% of the area under the normal curve lies to the right of 8.2 . Consider what would happen if you were to change the mean to 50 and keep the standard deviation at 5 . Can you predict the new value for which approximately 5% of the area under the normal curve lies to the right of this value? Enter your answer accurate to one decimal place.
Using z-scores and the normal distribution, it is found that the new value would be of 58.2.
In a normal distribution with mean and standard deviation , the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X, which is the area to the left of Z under the normal curve.The area to the right of Z is 1 subtracted by the p-value of Z.In this problem:
Mean of 50 and standard deviation of 5, thus [tex]\mu = 50, \sigma = 5[/tex].Area to the right of 0.05, thus Z with a p-value of 1 - 0.05 = 0.95, thus [tex]Z = 1.645[/tex].We have to find the value of X, then:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]1.645 = \frac{X - 50}{5}[/tex]
[tex]X - 50 = 1.645(5)[/tex]
[tex]X = 58.2[/tex]
