the equation rewritten in exponential form is:
y = 3^x
How to rewrite the given expression?
Here we start with.
Log₃(y) = x
Remember that we can rewrite:
Log₃(y) = ln(y)/ln(3)
Then we can simplify so we get:
ln(y) = ln(3)*x
Now we just apply the exponential function to both sides:
exp(ln(y)) = exp(ln(3)*x)
y = (e^(ln(3))^x = 3^x
y = 3^x

51 is 33 1/3 of what number
Step-by-step explanation:
33 1/3 = (3×33 + 1)/3 = 100/3
51 = 100/3 × x
153 = 100x
x = 153/100 = 1.53
1.53 × 33 1/3 = 51

than metal park benches. There are 24 wooden benches.
How many metal benches are there?
There are 51 metal benches in the park
According to the question we have been given that
Number of wooden benches = 24
We have to calculate number of metal benches.
Let the number metal benches be x.
The according to the question
W = x - 27 where, W = wooden benches
Here , W = 24
Putting the required in the above equation for x we get
24 = x - 27
x = 24 + 27

Given the function f(x) = 4x − 1 and the linear function g(x), which function has a greater slope?
f(x) has a greater slope.

The slopes of f(x) and g(x) are the same.
The slope of g(x) is undefined.
After the solution, we can conclude that (A) the slope of f(x) is higher.
What is the slope?A line's steepness can be determined by looking at its slope. The slope is calculated mathematically as "rise over run" (change in y divided by change in x). The letter M stands for the slope of a function of the form y=Mx+C, so the slope of the function F(x) =4.Now that you have a function but can only evaluate it using a table, you can determine the slope using the following formula:
[tex]m=\frac{y^2-y^1}{x^2-x^1}[/tex]
Simply choose two points from the table to enter into the formula; in this example, we'll use points (4, 7) as our points 1 and our second point is (6,9).
This implies:
x¹ = 4y¹ = 7x² = 6y² = 9You just need to enter it into the formula:
m = 9-7/6-4m = 2/2m = 1Now that we know both slopes, you can see that g(x) has a slope of 1, while f(x) has a slope of 4, indicating that f(x) has a steeper slope than g(x).

Estimate the instantaneous rate of change of the function f(x)=−4x2−3x+1 at x=−3 using the average rate of change over successively smaller intervals.
The instantaneous rate of change of the function f(x) = −4x² − 3x + 1 at the point x = -3 is 21.
What is the instantaneous rate of change of the function at the given point?The instantaneous rate of change is simply the change in the derivative value at a specific point.
Given the data in the question;
f(x) = −4x² − 3x + 1Point x = -3To determine the instantaneous rate of change of the function, first find the derivative of the function.
f(x) = −4x² − 3x + 1
Applying sum rule, with respect to x
d/dx[ -4x² ] + d/dx[ -3x ] + d/dx[ 1 ]
[ 2 × -4x¹ ] + [ 1 × -3x⁰ ] + d/dx[ 1 ]
[ -8x ] + [ -3 ] + d/dx[ 1 ]
-8x - 3 + d/dx[ 1 ]
Differentiate using constant rule
-8x - 3 + [ 0 ]
-8x - 3
f'(x) = -8x - 3
Next, plug x = -3 into the derivative and simplify.
f'(x) = -8x - 3
f'(-3) = -8(-3) - 3
f'(-3) = 24 - 3
f'(-3) = 21

What is the conditional probability of getting an A on the third exam given that they got an A on the first exam, P(A third | A first)?So, according the question,
Let's assume, total no. of students in class is x.
So, we know that
Conditional probability P( A IIIrd | A Ist ) = [tex]\frac{P(III^{rd} \cap I^{st}) }{P(I^{st})}[/tex]
From question,
P( A IIIrd ∩ A Ist) = 12/x. and

plugging in say 5/2 in f(x) will give

So far we have [tex]\frac{(11^8)^2}{11^3} = \frac{11^{16}}{11^3}[/tex]

Find the standard deviation of this data set using the table method that is in the Course Notes, please show your work. You can think of the class of 7 students as a population.
For the given set of data, the value of mean is 83, median is 87 and standard deviation is 11.03
What is standard deviation?Standard deviation is a measurement of how evenly distributed a set of numbers is. Since the variance is the average of the squared deviations from the mean, it is the square root of the variance.
The mean score is - Sum of all scores / total number of scores
= 89 + 72 + 96 + 87 + 64 + 93 + 80 / 7
= 83
So the mean of given scores is 83
Median = central term
= 64, 72, 80, 87, 89, 93, 96
Median = 87
Mode of the data is - no mode as there are no recurring terms given
Standard deviation -
variance = (89 - 83)² +(72 - 83)² + (96 - 83)² + (87 - 83)² + (64 - 83)² + (93 - 83)² + (80 - 83)² / 7
