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.

Step-by-step explanation:

The above sentence contains 30 letters, including 3 "e"s, so the frequency of e is 3/30 = 0.1 = 10%

Answer:

[tex]A= P( 1 + \frac{r}{n})^{nt}\\[/tex]

P = 1000

r = 4.5% = 0.045

n = semi annually = 2

t = 4

[tex]A= 1000( 1 + \frac{0.045}{2} )^8 =1000(1 +0.0225)^8= \$ 1194.83[/tex]

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.

hope this helps! :)

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).

Step-by-step explanation:

The correct answer would be option (c) such that,

"If a population is The entire school faculty, a sample of the population could be "math teachers"."

We can observe that In options 2 that is subset of  option 1.

In option A, C, D subset clearly can we seen as option 1

and only in option B we can clearly see that 2 is the subset of 1.

Thus, correct answer would be "If a population is The entire school faculty;, a sample of the population could be "math teachers"."

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:

120

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
