what is the intersection points of f(x)=2x+7 and g(x)=x^2-1
Answers
2x+7=x²-1
x²-2x-8=0
(x-4)(x+2)=0
x=4, or x=-2
when x=4, f(x)=g(x)=15
when x=-2, f(x)=g(x)=3
so the intersecting points are (4, 15) and (-2, 3)
Dennis can load the car in 28 min. If Andy helps him it takes 21 min to load the car how long will it take Andy alone?
Answers
So,
The rate of Andy to load the car = y/x
And we given that: Dennis load the car in 28 min.
So,
The rate of Dennis to load the car = y/28
If both are loading the car in time = t = 21 min
then:
y = (y/x) t + (y/28) t ⇒ divide all equation by y and substitute with t
∴ 1 = (21/x) + (21/28) ⇒ multiply all equation by 28x
28x = 21*28 + 21x
28x - 21 x = 588
7x = 588
∴ x = 84 min.
Which mean Andy will take 84 min. to load the car alone.

Answers
The cost of each drink if 7 drinks cost $16.38 is $2.34.
What is Division?Division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.
Given that the cost of 7 drinks is $16.38. Therefore, the cost of each of the drink will be:
Cost of each drink = Cost of all the drinks / Number of drinks
= $16.38 / 7
= $2.34
Hence, the cost of each drink is $2.34.

find the slope of the line that passes through each set of points
Answers
If the points are (a,b) and (c,d), the slope would be (d-b)/(c-a).
Slope really means "how much does the y change when the x advances by 1?"
In above two points, the y-difference is d-b. However, the x-difference is not 1, but it is c-a. If we divide by c-a, we get the y difference as if x advanced by 1.
Let (4,5) = (x₁ , y₁) and (-3,-9) = (x₂ , y₂)
Slope = (y₂ - y₁) / (x₂ - x₁)
Slope = (-9 -5) / (-3 -4)
Slope = 14/7
Slope = 2
OR
Let (4,5) = (x₂ , y₂) and (-3,-9) = (x₁ , y₁)
slope = (5 - (-9)) / (4 - (-3))
slope = 14/7
slope = 2

If the circumference of a circle measures 3/2 π cm, what is the area of the circle in terms of π?
Answers
The area of the circle with a circumference of 3/2 π cm is 9/16 π cm².
Explanation:The question is asking about finding the area of a circle when the circumference is given. The formula to find the circumference of a circle is C = 2πr, where C is the circumference and r is the radius of the circle. Given that the circumference is 3/2 π cm, we can use this information to find the radius.
From the circumference equation, r = C/2π = (3/2π)/ 2π = 3/4 cm. Having the radius, we can then use the formula for the area of a circle, which is A = πr². As a result, the area of the given circle is π(3/4)² cm² which simplifies to 9/16 π cm².

456 000 has been rounded to the nearest thousand. What was the smallest possible number this could have been?
Answers
Answer:
The smallest possible number this could have been = 455500
Step-by-step explanation:
456000 has been rounded to the nearest thousand.
If the value is more than 456500 the value rounded to the nearest thousand is 457000.
If the value is less than 455500 the value rounded to the nearest thousand is 455000.
In between 455500 and 456500 the value rounded to the nearest thousand is 456000.
So, The smallest possible number this could have been = 455500

A net is a flat version of a three dimensional shape. Imagine that you have a tissue box. If you cut along the edges and laid out the pieces, you would have the net of the shape. The third choice gives the correct net that would fold back up to a rectangular solid with the given dimensions.
Final answer:
The correct net for a rectangular prism with width 3 cm, height 8 cm, and length 7 cm would consist of three rectangles side by side with a width of 3 cm, where the first and third rectangles have a length of 8 cm and the middle one 7 cm, and three additional rectangles underneath the middle one with widths of 8 cm, 3 cm, and 8 cm respectively.
Explanation:
We are trying to match a net with a solid figure, specifically a rectangular prism with dimensions of width 3 cm, height 8 cm, and length 7 cm. To find the correct net, we need to consider the faces of the rectangular prism and how they would lay out flat.
The correct net for this prism would need three rectangles side by side for the sides with a width of 3 cm. The lengths of these side rectangles should be equal to the height of the prism, which is 8 cm. The middle rectangle represents the base or the top of the prism and should have a length equal to the length of the prism, which is 7 cm. Moreover, attached to this middle rectangle, there should be three flaps representing the remaining faces of the prism; two with widths equal to the height (8 cm) and one width equal to the width of the prism (3 cm).
The only net description that matches our rectangular prism dimensions is: "A net is shown with 3 rectangles attached side by side all with width 3 centimeters. The length of the first and third rectangle is 8 centimeters and the middle is 7 centimeters. Underneath the middle rectangle are 3 more rectangles with the same length but widths of 8 centimeters, 3 centimeters, and 8 centimeters."

How much compound interest is earned on $2050 at 4% interest for 3 years, compounded annually? Give your answer in dollars and cents. Don’t forget to subtract P from A.
Answers
[tex]A = P ( 1 + \frac{r}{n}) ^{nt} [/tex]
Where A = Accrued amount
P = Principal amount
r = rate in decimal
t = number of years
n = compounding periods per unit of time
Your given:
P = $2050
r = 4% or 0.04
t = 3 years
n = 1 per yr
Now we insert that into your formula:
[tex]A = P ( 1 + \frac{r}{n}) ^{nt} [/tex]
[tex]A = 2050 ( 1 + \frac{0.04}{1}) ^{1.3} [/tex]
[tex]A = 2050 ( 1 + 0.04) ^{3} [/tex]
[tex]A = 2050 ( 1.04) ^{3} [/tex]
[tex]A = 2050 (1.124864 ) [/tex]
[tex]A = $2305.97 [/tex]
Now to get the interest just remember that:
I = A - P
I = $2,305.97 - $2,050
I = $255.97
So that is equal to 255 dollars and 97 cents
