Answer:
17.41
Step-by-step explanation:
497.50 x 0.035
Jodi's investment will earn $17.41 in interest in one year at an interest rate of 3.5%. Therefore, after one year, her investment will be worth $514.91.
Explanation:To find out how much Jodi's investment is worth in one year, we can use the formula for simple interest, which is Interest = Principal x Rate x Time. In this case, the principal is $497.50, the rate is 3.5% (or 0.035 in decimal form), and the time is 1 year.
So, the interest earned in one year would be $497.50 x 0.035 x 1 = $17.41.
To find the total worth of her investment after one year, we add the interest earned to the initial principal. So, $497.50 (the principal) + $17.41 (the interest) = $514.91. Therefore, her investment is worth $514.91 after one year.

The table below represents a linear function f(x) and the equation represents a function g(x):
x f(x)
−1 −5

g(x)
g(x) = 2x − 7
Part A: Write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x).
Part B: Which function has a greater y-intercept? Justify your answer.
Answer:
Part A:The function f(x) has a greater slope than function g(x).Part B:The function f(x) has a greater y-intercept than function g(x).Step-by-step explanation:
[tex]\text{The slope-intercept form of an equation of a line:}\\\\y=mx+b\\\\m-slope\\b-y-intercept\to(0,\ b)\\\\\text{The formula of a slope:}\\\\m=\dfrac{y_2-y_1}{x_2-x_1}\\\\=============================[/tex]
[tex]f(x):\\\\given:\ (-1,\ -5),\ (0,\ -1),\ (1,\ 3)\\\\m=\dfrac{3-(-5)}{1-(-1)}=\dfrac{8}{2}=4\\\\(0,\ -1)\to b=-1\\\\f(x)=4x-1\\\\---------------------------\\\\g(x)=2x-7\to m=2,\ b=-7[/tex]
Answer:
Part A: The slope of F(x) is greater than the slope of g(x)
Part B: The Y-intercept of f(x) is greater than that of g(x)
Step-by-step explanation:
To calculate the slope on f(x) we just have to take two points from the table and use the formula for slope:
[tex]m=\frac{y^{2} -y^{1} }{x^{2}- x^{1} }[/tex]
Now the points to use will be:
P1:(0,-1)
P2:(1,3)
Now we just put this values into the formula:
[tex]m=\frac{y^{2} -y^{1} }{x^{2}- x^{1} }[/tex]
[tex]m=\frac{3-(-1) }{1- (0)} }[/tex]
[tex]m=\frac{4}{1}\\ m=4[/tex]
Now to know the slope of g(x) we just have to remember that in the function form y=mx+c the "m" represents the slope, so if g(x)=2x-7 the slope would be "2".
Now we know that f(x) has a greater slope.
To know the greater Y intercept we just take the point in the table where x is "0" since it´s where the Y intercepts with the Y axis, and in f(x) that point is (0,-1), now in g(x) we just evaluate the function to x=0.
[tex]g(x)=2x-7\\g(x)=2(0)-7\\g(x)=-7[/tex]
The Y intercept in g(x) would be in (0,-7), since -1 is greater than -7, we can say that f(x) has the greatest Y-intercept.

The population (in millions) of a certain country can be approximated by the
function:
P(x) = (100)1.02^x
where x is the number of years after 2000. Which of the following calculations will tell in what year the population can be expected to reach 300 million?
To calculate the year in which the population of the country is expected to reach 300 million, set up and solve the provided equation involving the population function. By following the steps of solving for x, you can identify the specific year when the population is estimated to reach 300 million.
To find in what year the population can be expected to reach 300 million, we can set up the equation:
P(x) = 100 * 1.02^x = 300
Now, solve for x:
1.02^x = 3x = log1.02(3)Calculate x to get the number of years after 2000, which will give you the year the population is expected to reach 300 million.-2(5x+8)=14+6x complete the statements below with the process used to achieve steps 1-4
Expand -2(5x+8), simplify, isolate x by moving terms, and solve to get x = -15/8.
To solve the equation -2(5x + 8) = 14 + 6x step by step, here's what was done:
Step 1: Expand the left side of the equation by distributing -2 across the terms inside the parentheses:
-2(5x + 8) = -2 * 5x - 2 * 8 = -10x - 16
So, the equation becomes: -10x - 16 = 14 + 6x
Step 2: Group like terms together. Subtract 6x from both sides to get all the x terms on one side of the equation:
-10x - 6x = 14 + 16
This simplifies to: -16x = 30
Step 3: Now, isolate the variable by dividing both sides by -16:
(-16x)/(-16) = 30/(-16)
This simplifies to: x = -30/16 or x = -15/8
So, the solution for x is x = -15/8.

Jonah and his brother want to earn at least $400 this month, so they rented a lawn mower to mow lawns. They plan to charge $25 per lawn. The monthly rental fee for the lawn mower is $85. At this rate, what is the fewest number of lawns Jonah and his brother would have to cut to make their goal? Let m represent the number of lawns mowed. In the box, enter the inequality that models the situation.
Answer: 400<=25m-85
Step-by-step explanation: 400 is how much he wants to AT LEAST make so it’ll be more than or equal to four hundred. Then he gets payed 25 dollars per law. Number of laws are unknown so its m making 25m. Lastly he has to pay 85 dollars for the law mower so that subtracts his from his pay making it 25m-85.
A number is 5 more than 3 times another number. The sum of the two numbers is 33. As an equation, this is written x + 3x + 5 = 33, where x represents the smaller number. Plug in the numbers from the set {3, 5, 7, 9} to find the value of x.
The value of x that holds true for the equation is blank . So, the smaller number is blank and the larger number is blank .
Answer:
x=7
Step-by-step explanation:
Solve for x:
3 x + x + 5 = 33
x + 3 x = 4 x:
4 x + 5 = 33
Subtract 5 from both sides:
4 x + (5 - 5) = 33 - 5
5 - 5 = 0:
4 x = 33 - 5
33 - 5 = 28:
4 x = 28
Divide both sides of 4 x = 28 by 4:
(4 x)/4 = 28/4
4/4 = 1:
x = 28/4
The gcd of 28 and 4 is 4, so 28/4 = (4×7)/(4×1) = 4/4×7 = 7:
Answer: x = 7
The larger number is 26 and the smaller number is 7.
What are the numbers?To determine the solution, take the following steps:
The given equation is x + 3x + 5 = 33
Combine similar terms: x + 3x =33 - 5
Add similar terms: 4x = 28
Divide both sides by 4 : 7
The larger number = 33 - 7 = 26

[tex]AC = 2\pi[/tex]
Step-by-step explanation:
The arc length is calculated as
[tex]L = \theta * R[/tex]
Then
[tex]AC = \theta * R[/tex]
We know that
[tex]BC = 24\ ft[/tex]
If BC is the diameter of the circumference then the radius R is:
[tex]R = \frac{BC}{2}[/tex]
[tex]R = \frac{24}{2}[/tex]
[tex]R = 12\ ft[/tex]
Now we convert the anglo from degrees to radians[tex]\theta= 30\° * \frac{\pi}{180\°}\\\\\theta=\frac{1}{6}\pi[/tex]
Finally
[tex]AC = \frac{1}{6}\pi * 12[/tex]
[tex]AC = 2\pi[/tex]
Answer:
The length of the arc AC is 2π ⇒ answer C
Step-by-step explanation:
* Lets revise some facts in the circle
- The length of the arc is depends on the measure of the arc and the
radius of the circle
- The length of the arc is a part of the length of the circle
- The length of the circle is 2πr
- The rule of the length of the arc = [tex]\frac{\alpha }{360}*2\pi r[/tex],
where α is the measure of the arc
* Now lets solve the problem
- In circle P
∵ BC is a diameter
∵ BC = 24 ft
∵ The length of the radius of the circle is 1/2 the length of the diameter
∴ The length of the radius = 1/2 × 24 = 12 ft
- Ac is an arc in the circle
∵ The measure of the arc = 30°
∵ The length of the arc = [tex]\frac{\alpha }{360}*2\pi r[/tex] ,
where α is the measure of the arc
∴ α = 30°
∵ r = 12 ft
∴ The length of the arc = [tex]\frac{30}{360}*2(12)\pi=\frac{1}{12}*(24)\pi=2\pi[/tex]
∴ The length of the arc AC is 2π

According to the synthetic division below, which of the following statements are true
Answer:
B and D
Step-by-step explanation:
The polynomial x² + 6x - 8 ( from values in first row )
is being evaluated at x = - 5 thus the factor is (x + 5)
If (x + 5) is a factor the remainder = 0
Hence (x + 5) is not a factor since remainder = 12 ≠ 0
When the polynomial is evaluated at x = 5 it's value is 12
The remainder theorem states that f(h) = remainder, hence
f(- 5) = 12 ← remainder

Find the difference.
(-5ab+a+3) - (ab+2)
Enter the correct answer.
Need help ASAP !!!!
Answer:
-6ab+a+1
Step-by-step explanation:
add or subtract like terms.
The difference between (-5ab+a+3) and (ab+2) is calculated by combining like terms and performing the subtraction, resulting in -6ab + a + 1.
To find the difference between the two expressions (-5ab+a+3) and (ab+2), we need to subtract the second expression from the first. Applying the distributive property of subtraction over addition (i.e., a - (b + c) = a - b - c), we get:
-5ab - ab: Combine like terms by subtracting ab from -5ab which gives us -6ab.+ a: There's no like term to combine with a in the second expression, so it remains as is.+ 3 - 2: Subtract 2 from 3 which gives us +1.Putting it all together, the difference of the two expressions is -6ab + a + 1.
