Answer:An exponential function is defined by the formula f(x) = ax, where the input variable x occurs as an exponent. The exponential curve depends on the exponential function and it depends on the value of the x.
Step 1: Take the natural log of both sides:
Step 2: Simplify the left side of the above equation using Logarithmic Rule 3:
Step 3: Simplify the left side of the above equation: Since Ln(e)=1, the equation reads
Ln(80) is the exact answer and x=4.38202663467 is an approximate answer because we have rounded the value of Ln(80)..
Check: Check your answer in the original equation.
Example 2: Solve for x in the equation tex2html_wrap_inline133
Step 1: Isolate the exponential term before you take the common log of both sides. Therefore, add 8 to both sides: tex2html_wrap_inline135
Step 2: Take the common log of both sides:
Step 3: Simplify the left side of the above equation using Logarithmic Rule 3:
Step 4: Simplify the left side of the above equation: Since Log(10) = 1, the above equation can be written
Step 5: Subtract 5 from both sides of the above equation:
is the exact answer. x = -3.16749108729 is an approximate answer..

How do you solve this?
Answer:
C.)
Step-by-step explanation:
The graph is positive this time, so right away you can eliminate A and B.
If y=2x, the graph would be much steeper so the answer is C.) you can also check by graphing it in desmos.
Answer: C: 1/2
Step-by-step explanation:
Rise over run tells us that this graph is going up 1 and right 2. Since it’s going up and right it’s going to be positive and since we do rise over run on our slope fraction, that leaves us with C, 1/2.
A bag of jelly beans contains 20 blue jelly beans, 52 yellow jelly beans, 34 green jelly beans, 71 orange jelly beans, and 23 red jelly beans. What percentage of the jelly beans are yellow?
Answer: 26%
Step-by-step explanation:
20+52+34+71+23= 200
52/200 = 26/100
Answer:
26% of the jelly beans are yellow
Step-by-step explanation:
To find this we add up all the jelly beans which is 200 jelly beans
Then we divide it by the number of yellow jelly beans which is 52/200
which then equals .26. In a percentage that is 26%

Naman is 4 times as old as his sister now.
In 20 years’ time, Naman’s age will be 14
years less than twice his sister’s age. How old is Naman now?
Answer:
Naman is 12 years old
Step-by-step explanation:
This means his sister is 3 which means in 20 years Naman will be 32 and his sister will be 23. Double 23 and you get 46 and 46 - 32 is 14

A) The first dot plot is skewed to the right.
B) The second dot plot has more of a "bell-shaped" curve than the first dot plot.
C) The first dot plot has a unimodal distribution and the second dot plot has a uniform distribution.
D) The second dot plot looks to have a trimodal distribution.
Answer:
C
Step-by-step explanation:
unimodel: A unimodal distribution is a distribution with one clear peak or most frequent value. The values increase at first, rising to a single peak where they then decrease.

What is the cost of one sandwich?
What is the cost of 1 sandwich 1 salad and 1 juice?
Answer:
Below in bold.
Step-by-step explanation:
Let cost of sandwich = s, juice = j and salad = d.
2s + j = 500 (A)
s + d = 510 (B)
d + j = 530 (C)
Equation (C) - (B) ( to eliminate d):
j - s = 20 (D)
(A) - (D) = (to eliminate j):
2s - (-s) = 480
3s = 480
s = 160

A construction company needs to remove 2 1/6 tons of dirt from a construction site. they can remove 7/8 of dirt each hour. what is the total number of hours it will take to remove the dirt each hour? write your answer as a mixed number and simplest form.
Answer: 2.357hrs
Step-by-step explanation:
Rate of dirt removal (rate) = 7/8 tons/hr
Total dirt removed (dirt) = 2 1/16 tons
Each hour, 7/8 tons of dirt will be removed, so if you work for h hours, you will have removed 7/8 * x tons of dirt. You can set up an equation as follows:
7/8 tons/hr * h hr = 2 1/16 tons (see how the units work out to give you tons)
Rearrange and solve for h:
h = (2 1/16) / (7/8) = 33/14 hrs = 2.357hrs

Find equation of parabola with vertex (8,-1) and which passes through point (-5,9)
Answer:
[tex]\displaystyle f(x)=\frac{10}{169}\left(x-8\right)^2-1[/tex]
Step-by-step explanation:
We can use the vertex form of a quadratic, which is given by:
[tex]\displaystyle f(x)=a(x-h)^2+k[/tex]
Where (h, k) is the vertex.
Since we are given that the vertex is (8, -1), h = 8 and k = -1. Substitute:
[tex]f(x)=a(x-8)^2-1[/tex]
Next, we are given that the parabola passes through the point (-5, 9). So, when x = -5, y = 9:
[tex]9=a((-5)-8)^2-1[/tex]
Solve for a:
[tex]9=a(-13)^2-1[/tex]
So:
[tex]\displaystyle a=\frac{10}{169}[/tex]
So, the equation of our parabola is:
[tex]\displaystyle f(x)=\frac{10}{169}\left(x-8\right)^2-1[/tex]
Answer:
The equation of our parabola would be:
f(x) = 10/169(x - 8)[tex]^{2}[/tex] - 1

Select the statement that describes the expression 6 x one third x (12 − 3).
A 6 times one third the quotient of 12 and 3
B 6 times one third the sum of 12 and 3
C 6 times one third the product of 12 and 3
D 6 times one third of the difference of 12 and 3
Answer:
D
Step-by-step explanation:
6 x 1/3 = 2
1/3 x (12-3) = 2 x 9
2 x 9 = 18
A = 2 (12/3) = 2 x 4 = 8
B = 2 x 15 = 30
C = 2 x 36 = 72
D = 2 x 9 = 18

Round to the nearest whole feet.
Answer:
2544 ft
Step-by-step explanation:
First, find the area of the pool.
A= πr²
if we fill in the radius, use 3.14 for pi, and solve for A, that's
A=(3.14)(20.5)²≈1319.585
The area of the pool is roughly 1319.585 ft
Now, we find the area of the triangle
A=(ab)÷2
put in 'a' and 'b' (the triangle legs) and solve
A=(84×92)÷2=3864
Finally, subtract the area of the pool from that of the triangle
3864-1319.585=2544.415 which rounds to 2544 ft
hopefully that helps and you might want to double check but that's what I got :)
