Find the intersection points of the linear and quadratic functions shown below f(x)=2x-5 g(x)= x2+2x-21
Answer:
[tex](-4,-13)[/tex] and [tex](4,3)[/tex] the intersection points.
Step-by-step explanation:
Intersection point of two functions is a common point which satisfies both the functions.
Given functions are,
[tex]f(x)=2x-5[/tex]
[tex]g(x)=x^2+2x-21[/tex]
For a common point of these functions,
[tex]f(x)=g(x)[/tex]
[tex]2x-5=x^2+2x-21[/tex]
[tex]-5=x^2-21[/tex]
[tex]0=x^2-16[/tex]
[tex]x^2=16[/tex]
[tex]x=-4,4[/tex]
For [tex]x=-4[/tex],
[tex]f(-4)=g(-4)=2(-4)-5[/tex]
[tex]=-13[/tex]
For [tex]x=4[/tex],
[tex]f(4)=g(4)=2(4)-5[/tex]
[tex]=3[/tex]
Therefore, [tex](-4,-13)[/tex] and [tex](4,3)[/tex] the intersection points.

Marissa earned $2,250 this month. She has expenses of rent of $800, car payment is $225, utilities are $75, Insurance is $200, car maintenance of $200, and groceries/household supplies at $300. She needs to purchase a new washer and dryer set this month and the lowest price she could find is $500. Can Marissa afford the washer and dryer set this month? Should she save and purchase the set in the following month?
Answer:
The final answer is she should save and purchase the set next month because she has only 450 this month.
Step-by-step explanation:
2250 - 800 -75 - 225 - 200 - 200 - 300 = 450

Answer:

Step-by-step explanation:
The prism shown is a triangular prism
The volume of a triangular prism can be found by multiplying the area of the base ( which is a triangle ) by the length of the prism ( which is 10 feet )
First let's find the area of the base.
To find the area of a triangle we use this formula [tex]A=\frac{bh}{2}[/tex]
where b = base length and h = height
The base length is 6ft and the height is 4ft.
Using these dimensions we plug in the values into the formula
[tex]\frac{4*6}{2} \\4*6=24\\\frac{24}{2} =12[/tex]
So the area of the base is 12ft²
Finally to find the volume we multiply the area of the base by the length of the prism
12 * 10 = 120
Hence, the volume of the prism is 120ft³
Segment AB is shown on the graph. Which shows how to find the x-coordinate of the point that will divide segment AB into a 2:3 ratio using the formula…
PLEASE HELP!!
Answer:
[tex]x=\dfrac{2}{5}\times (2+3)-3[/tex]
Step-by-step explanation:
The given ratio is 2:3.
x₁ = -3, x₂ = 2
We need to find the x-coordinate of the point that will divide segment AB into a 2:3 ratio. The formula is as follows :
[tex]x=\dfrac{a}{a+b}(x_2-x_1)+x_1[/tex]
Put all the values,
[tex]x=\dfrac{2}{2+3}(2-(-3))+(-3)\\\\=\dfrac{2}{5}\times (2+3)-3[/tex]
Hence, the correct option is (d).

Tonia contributes 5% of her paycheck to her 401(k) plan in order to save for her retirement, and she pays state income tax at a rate of 5% on the rest of her paycheck. If p represents Tonia's paycheck and t represents the amount she pays in state income tax, which of these equations represents this Situation? А t = 0.0025p t = 0.025p С 1 = 0.0475p D 1 = 0.475p
Answer:
t = 0.0475p
Step-by-step explanation:
If
p = paycheck ; t = amount paid in state income tax
Amount contributed towards retirement :
5% of p ; 0.05p
Amount left :
Paycheck - contribution
p - 0.05p = 0.95p
Amount paid in state income tax :
5% of amount left
5% of 0.95p
5/100 * 0.95p
0.05 * 0.95p
= 0.0475p
Hence, state income tax, t = 0.0475p

Answer:
look at the picture i have sent
Answer:
d
Step-by-step explanation:
this shape is made up of a triangular prism and a rectangular prism. the formula for the volume of a prism (any prism, doesn't matter) is base area times height. the base areas of the rectangular prism can be found by multiplying 4*12, as these are the dimensions of the base rectangle. 4*12=48. we now multiply this number by the height of the rectangular prism as shown in the volume of a prism formula. the height of the rectangular prism is 14, so 48*14=672. the volume of the rectangular prism is 672 cm^3.
now for the triangular prism. the bases of the triangular prism are the two triangle shapes on the ends; a prism is named after the shape of its base, so be sure to note that you use the triangles for the formula and not the rectangle on the bottom. to find the area of one of these bases (they are both the same), we use the triangle area formula, 1/2*base*height. the base of the triangle shape is 4 units long, as seen by the measurements of the rectangle this triangle sits on top of. to find the height of this triangle, which isn't given, we must use the pythagorean theorem, a^2+b^2=c^2. c in this case is equal to 4 as that is the hypotenuse, and a and b are interchangeable. since the pythagorean theorem only works for right triangles, we must cut the base length in half to assume that the final side is a vertical line, which will give us the height of the original triangle. (note: halving the base length in order to apply the pythagorean theorem only works in this case because both of the other sides are equal length, as we can see on the far triangle, so make sure this applies before trying it in another context) the halved base length is 2, and this number can be either a or b, doesn't matter because the formula adds them. so: (2)^2+b^2=4^2. 2^2 is 4, and 4^2 is 16. 4+b^2=16. subtract 4 from both sides, leaving you with b^2=12, and to get rid of the square on b you take the square root of both sides. so the height of this triangle is the square root of 12, which doesn't need to be simplified if you have a calculator that can process square root input. so to find the area of this triangle, we convert the equation 1/2*base*height into 1/2*4*square root of 12. this gets you about 6.93. to find the total volume of this prism, you multiply the base area times height. as we just figured out, the base area is 6.93, and the height is 12, because this is the length between the two bases, which are the triangles. so, 6.93*12=83.16 is the volume of the triangular prism. the final step is to add this to the volume of the rectangular prism, which is 672. 672+83.16= 755.16 cm^3.

Alma just turned 15 years old. Her parents started saving $300 each month for her college education when she was born. Her parents want to save at least $150,000 by the time she turns 18 to cover tuition expenses at a 4-year college. How much would they need to save each month for the next 3 years to reach their goal?
Answer:
Its letting me answer now, so $2,666!
Step-by-step explanation:
First, you wanna find out how much money they have saved. So, since they saved $300 a month, and shes 15, to find out how much they have we have to multiply 300 by the amount of months. Shes 15 and there are 12 months in a year, so 15 x 12 = 180. So thats 180 months, so, 180 x 300 = 54,000. That means so far they have saved 54,000. Well, we need to find how much more money they need. So, the total 150,000 - 54,000 = 96,000. They need 96,000 more dollars. So, lets divide that by 3 years, which is 36 months, since they only have that much time to save. 96,000/36 = 2,666 dollars. I hope that helps you understand! I would really appreciate it if I could have brainliest!
