Step-by-step explanation:

Given:

The vertex of a quadratic function is (-5,-1) and it passes through the point (-2,2).

To find:

The vertex and standard form of the quadratic function.

Solution:

The vertex form of a quadratic function is:

[tex]f(x)=a(x-h)^2+k[/tex]

Where, a is a constant, (h,k) is vertex.

The vertex of a quadratic function is (-5,-1). It means [tex]h=-5,k=-1[/tex].

[tex]f(x)=a(x-(-5))^2+(-1)[/tex]

[tex]f(x)=a(x+5)^2-1[/tex]             ...(i)

The quadratic function passes through the point (-2,2). Putting [tex]x=-2,f(x)=2[/tex] in (i), we get

[tex]2=a(-2+5)^2-1[/tex]

[tex]2+1=a(3)^2[/tex]

[tex]3=9a[/tex]

[tex]\dfrac{1}{3}=a[/tex]

Putting [tex]a=\dfrac{1}{3}[/tex] in (i), we get

[tex]f(x)=\dfrac{1}{3}(x+5)^2-1[/tex]

Therefore, the vertex for of the quadratic function is [tex]f(x)=\dfrac{1}{3}(x+5)^2-1[/tex].

The standard form of a quadratic function is:

[tex]f(x)=Ax^2+Bx+C[/tex]

We have,

[tex]f(x)=\dfrac{1}{3}(x+5)^2-1[/tex]

[tex]f(x)=\dfrac{1}{3}(x^2+10x+25)-1[/tex]

[tex]f(x)=\dfrac{1}{3}x^2+\dfrac{10}{3}x+\dfrac{25}{3}-1[/tex]

[tex]f(x)=\dfrac{1}{3}x^2+\dfrac{10}{3}x+\dfrac{22}{3}[/tex]

Therefore, the standard form of a quadratic function is [tex]f(x)=\dfrac{1}{3}x^2+\dfrac{10}{3}x+\dfrac{22}{3}[/tex].

Answer:

L's coordinates would go from being (x,y) to (-x, -y)

Step-by-step explanation:

So like, if L's coordinates were (5, 7) after rotation it would be (-5, -7)

If you were working backward and with L' being rotated you would do (-5, -7) change the sign and do (5,7) for L

Consenquently if you had a negative to begin with- L (-3, -4) L' would be the opposite sign and be (3,4)

Answer:

Conner's work is correct

Step-by-step explanation:

In exponent multiplication, if base are same, add the exponents.

[tex]a^{m}*a^{n} =a^{m+n}[/tex]

For example,

5² * 5³

5² = 5 * 5

5³ = 5* 5 * 5

5² * 5³ = 5 * 5 * 5 * 5 * 5 = 5⁵ = 5⁽²⁺³⁾

Answer:

Step-by-step explanation:

8/24 are Red

Pick and return 2

So it will be 7/25

Again pick and return 2

Then it is 6/26

Now multiply the results

8/24 × 7/25 × 6/26 = 7/ 325

The probability that all three discs are taken out of red will be 7/ 325.

Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Probability = Number of favourable outcomes / Number of sample

Given that a bag contains 24 discs. 8 are red and 16 are blue. One disc is taken out at random and replaced by two of the other colour. Another disc is then taken out at random and replaced by two of the other colour.

The probability will be calculated as,

Red = 8/24

Pick and return 2 it will be 7/25

Again pick and return 2 then it is 6/26

Now the overall probability will be,

P = 8/24 × 7/25 × 6/26 = 7/ 325

Therefore, the probability that all three discs are taken out of red will be 7/ 325.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Answer:

A. Y = 144/x

Step-by-step explanation:

Inversely means y = 1/x

If y = 48, when x = 3

so 144/3 = 48

Therefore the answer is A

If the  value of y varies inversely with x then the function Y= 144/x represents the relationship between x and y if y = 48 when x = 3

A relation is a function if it has only One y-value for each x-value.

If y varies inversely with x, it means that y is inversely proportional to x, or y=k/x, where k is a constant of proportionality.

To find k, we can use the given values of y and x:

y = k/x

48 = k/3

k = 144

Now that we know k, we can write the function that represents the relationship between x and y:

y = 144/x

Therefore, if the  value of y varies inversely with x then the function Y= 144/x represents the relationship between x and y if y = 48 when x = 3

Answer:

circumference = pi (3.14 or 22/7, whatever your teacher wants or whatever the problem asks) x the diameter

Step-by-step explanation:

Answer:

To calculate the circumference of a circle, multiply the diameter of the circle with π (pi). The circumference can also be calculated by multiplying 2×radius with pi (π=3.14).

Step-by-step explanation:

I hope the images help!!

Answer:

False; True; True

Step-by-step explanation:

If the radius is 4, the area of the circle is

pi*r*r = pi * 4 * 4 = 16pi; The second statement is true.

The entire circle's "angle" is 2pi, so the sector takes (2pi/3) / 2pi of it all, equal to 1/3 of the entire circle - hence the area of the sector is

16pi * 1/3 = 16pi/3; the first statement is false

The length of the entire circle is 2 * pi * r = 2 * pi * 4 = 8pi

The sector is 1/3 of that, so 8pi/3; the third statement is true.

Step-by-step explanation:

no.1 first write the equation

the write the sum and the product

so the sum will be 8x and the product

will be 15.In the product part look for a no

that when you multiply it by another no

it will give you 15 by when you add it will

become 8.The no.is 5 and 3.you now rewrite the equation x^2+3x+5x+15=0

you now simply the equation x(x+3)+5(x+3)

you take (x+3)and (x+5)=0.

your answer will either be -3or-5 respectively

Answer:

b. -6 and 6

Step-by-step explanation:

Answer:

B. -6 and 6.

Step-by-step explanation:

It's shown that -2 and 2 are the inputs on this particular equation. That means they are the x values they want you to find the corresponding y value for. So, you can solve these by just plugging in the numbers. So, replace x in the original equation with -2 and 2 and then evaluate. [tex]f(x)=3 *-2=-6[/tex] and [tex]f(x) = 3*2=6[/tex]. Good luck!

Answer:

Triangle

Step-by-step explanation:

A pyramid is a strong-solid shape that is comprised of triangles, square shapes, squares, and different polygons. Pyramids are arranged depending on the state of their base. For instance, the outline given is a square-based pyramid in light of the state of its base(which is a square). Different sorts incorporate the three-sided based pyramid, three-sided based pyramid, and other polygon-based pyramids.  

In the event that this square pyramid is cut with a plane that is corresponding to the base of the pyramid, the state of its cross-area will be a triangle since the shapes that are corresponding to the base are altogether triangles. So slicing the plane corresponding to the base is like removing one side of the triangle making up the pyramid.

y=(-1/3)x

Step-by-step explanation:

y=mx+b

(x,y)

put in the first point into y=mx+b

2=m(-6)+b

then the second point is (6,-2)

put the point into y=mx+b

-2=6m+b

----------------------------

Put both equations in a system of equations

-2=6m+b

2=m(-6)+b

solve for m and b

-1/3=m and 0=b

so put that back into y=mx+b

y=(-1/3)x+0

so that is the only line that passes through both points
