In the graphing tool, choose the custom option in the Relationship menu to graph the functions f(x) = x3 + 3 and g(x) = x2 + 2. Adjust the zoom level of the graph so you can see the point where the two graphed functions intersect. Then, left-click on the point where the functions intersect. The values of the point you click on, rounded to the nearest hundredth, will appear for about 2 seconds. Note: If you’re not using a mouse (or a mouse with left-click ability), perform the equivalent zoom-in action on your device to see the intersection point values rounded to the nearest hundredth. Then, approximate (to the nearest hundredth) the solution of f(x) = g(x) from part A of this question.
Answers
Answer:
Final answer is x= -0.76 and y=2.57.
Step-by-step explanation:
We have been given two functions [tex]f(x)=x^3+3[/tex] and
[tex]g(x)=x^2+2[/tex]
Now question says to graph the given functions [tex]f(x)=x^3+3[/tex] and
[tex]g(x)=x^2+2[/tex] using some graphing tool. Then zoom as per requirement so that you can see the intersection point and read that point from graph which should be correct up to hundredth decimal place.
I'm using Desmos graphing calculator. Just type both functions then it will create graph for you. Click on intersection point as you can see in the attached picture. They intersect at point (-0.755,2.57).
Hence final answer is x=-0.76 and y=2.57.
Answer:
(-0.76, 2.57)Step-by-step explanation:
The given functions are
[tex]f(x)=x^{3}+3\\ g(x)=x^{2} +2[/tex]
If we wanna find [tex]f(x)=g(x)[/tex] we can just graph and see such point, or we can do some algebra to find it. This problem, specifically, asks an answer using a graphic method. The graph with both functions is attached.
You can see that the interception point is (-0.755, 2.57), which rounded to the nearest hundred is (-0.76, 2.57). At this point the functions are equal ([tex]f(x)=g(x)[/tex]), that's what an interception means.
We obtained this point by just left-clicking on the interception point, as the problem indicates.

Answers
Answer:
$100
Step-by-step explanation:
if $20 is needed for one bus tip, then $40 is needed for the two buses that the teachers will need
so $240 - $40 = $200 to spend on bus rentals
since there are two buses, the $200 needs to be halved
therefore, each bus rental is $100

In a rectangle, the ratio of the length to the width is 5 : 2. The length of the rectangle is 13.875 feet greater than the width. What are the perimeter and the area of the rectangle?
Answers
Answer:
Perimeter = 64.75 ft
Area = 213.91 ft
Step-by-step explanation:
13.875 ÷ 3 = 4.625
4.625 x 5 = 23.125 ft (This is the length of the rectangle)
4.625 x 2 = 9.25 ft (This is the width of the rectangle)
(23.125 x 2) + (9.25 x 2) = 64.75 ft (Perimeter)
23.125 x 9.25 = 213.90625 ft, or 213.91 ft if rounded to 2 d.p (Area)
The perimeter of the rectangle is approximately 64.75 feet and the area is approximately 213.91 square feet.
How to solve for the area and perimeter[tex]\[L = W + 13.875\][/tex]
We can use these two equations to solve for the values of \(L\) and \(W\).
First, let's use the ratio to set up an equation:
[tex]\[\frac{L}{W} = \frac{5}{2} \implies L = \frac{5}{2}W\][/tex]
Next, substitute this expression for L into the second equation:
[tex]\[\frac{5}{2}W = W + 13.875\][/tex]
Solving for w
[tex]\[\frac{3}{2}W = 13.875\][/tex]
[tex]\[W = \frac{2}{3} \times 13.875\][/tex]
[tex]\[W = 9.25\][/tex]
Now, use this value of \(W\) to find the length \(L\):
[tex]\[L = \frac{5}{2} \times 9.25 = 23.125\][/tex]
Now that we have the dimensions, we can calculate the perimeter and area:
1. perimeter of a rectangle with length \(L\) and width \(W\) is given by:
[tex]\[P = 2(L + W)\][/tex]
Substituting the values:
[tex]\[P = 2(23.125 + 9.25) \approx 64.75 \text{ feet}\][/tex]
2. Area of a rectangle is given by:
[tex]\[A = L \times W\][/tex]
Substituting the values:
[tex]\[A = 23.125 \times 9.25 \approx 213.91 \text{ square feet}\][/tex]
So, the perimeter of the rectangle is approximately 64.75 feet and the area is approximately 213.91 square feet.

Answer:
x = ± [tex]\sqrt{2}[/tex]
Step-by-step explanation:
given the 3 terms of a geometric sequence
[tex]\sqrt{x-1}[/tex], 1, [tex]\sqrt{x+1}[/tex], then the common ratio r
r = [tex]\frac{\sqrt{(x+1)} }{1}[/tex] = [tex]\frac{1}{\sqrt{(x-1)} }[/tex] ( cross- multiply )
[tex]\sqrt{(x+1)(x-1)}[/tex] = 1 ( square both sides )
(x + 1 )(x - 1 ) = 1 ← expand factors on left side )
x² - 1 = 1 ( add 1 to both sides )
x² = 2 ( take the square root of both sides )
x = ± [tex]\sqrt{2}[/tex]
The value of x is ±[tex]\sqrt{2}[/tex].
What is a Geometric Sequence?It is a sequence, where the ratio of two consecutive terms in a sequence are constant.It is a finite or infinite sequence.Geometric Sequence G is given by: G = a, ar², ar³,..... (a = first term; r = constant ratio)Given:
Geometric Sequence with first three terms.
[tex]\sqrt{x-1},1, \sqrt{x+1[/tex]
We have to find the value of x.
Now, if the given sequence is geometric then we can find the common ratio of the sequence.
The common ratio is given by:
r = [tex]\frac{1}{\sqrt{x-1} }[/tex] and r = [tex]\frac{\sqrt{x+1} }{1}[/tex]
Now, we can equate the both the values of r to solve for the value of x.
[tex]\frac{\sqrt{x+1} }{1} = \frac{1}{\sqrt{x-1} }[/tex]
Now, multiplying the numerator on both sides by [tex]\sqrt{x-1}[/tex], we get:
[tex]\sqrt{x+1} \sqrt{x-1} =1[/tex]
[tex]\sqrt{(x-1)(x+1)}=1[/tex]
[tex]\sqrt{x^2-1} =1[/tex]
Now, squaring on both sides of the equation, we get:
⇒ x² - 1 = 1
⇒ x² = 2
Now, taking square root on both the sides, we get:
⇒ x = ±[tex]\sqrt{2}[/tex]
Therefore, for a given geometric sequence the value of x will be ±[tex]\sqrt{2}[/tex].

Medicare 1.45%, federal withoutholding tax $73.25, state withholding tax $22.50, and health insurance $37.47. What is her net pay if she is paid biweekly?
Answers
Answer: $ 753.34
Step-by-step explanation:
Since, here She earns $12 an hour and works 40 hours each week.
Therefore, her earning in two weeks = 2 × 12 × 40 = $ 960
Now, Her biweekly deductions are Social Security 6.2%. Medicare 1.45%, federal with out holding tax $73.25, state withholding tax $22.50, and health insurance $37.47.
Therefore, Her total deduction = (6.2+1.45)% of 960 + (73.25+22.50+37.47)= 73.44+133.22= 206.66
Since, Net pay is the amount of payee after deductions have been taken from the his gross pay.
Therefore, Net pay = total amount - total deduction = 960 - 206.66 = $ 753.34
Her net pay if she is paid biweekly is $ 753.34.
we have given that,
She earns $12 an hour and works 40 hours each week.
Therefore, her earning in two weeks,
= 2 × 12 × 40
= $ 960
Her biweekly deductions are Social Security 6.2%. Medicare 1.45%, federal with out holding tax $73.25, state withholding tax $22.50, and health insurance $37.47.
Therefore,
[tex]Her total deduction = (6.2+1.45)% of 960 + (73.25+22.50+37.47)\\\\\\\\Her total deduction= 73.44+133.22\\ \Her total deduction= 206.66[/tex]
What is the net pay amount formula ?Net pay is the amount of payee after deductions have been taken from the his gross pay.
Net pay = total amount - total deduction

Answer: p(x) = 8.7x - 1940
p(500) = $2410
p(1000) = $6760
p(5000) = $41,560
Step-by-step explanation:
p(x) = r(x) - c(x)
= 9.5x - (0.8x + 1940)
= 9.5x - 0.8x - 1940
= 8.7x - 1940
**********************************************************************
p(500) = 8.7(500) - 1940
= 4350 - 1940
= 2410
p(1000) = 8.7(1000) - 1940
= 8700 - 1940
= 6760
p(5000) = 8.7(5000) - 1940
= 43,500 - 1940
= 41,560
***************************************************************************
p(500) = r(500) - c(500)
= 9.5(500) - [0.8(500) + 1940]
= 4750 - (400 + 1940)
= 4750 - 2340
= 2410
p(1000) = r(1000) - c(1000)
= 9.5(1000) - [0.8(1000) + 1940]
= 9500 - (800 + 1940)
= 9500 - 2740
= 6760
p(5000) = r(5000) - c(5000)
= 9.5(5000) - [0.8(5000) + 1940]
