What's the error and the answer​

Answer:

Step-by-step explanation:

The vertex form of the equation of the parabola with vertex (h, k)  is:

f(x) = a(x - h)² + k

so the equation of parabola with the vertex (3, 6) is

f(x) = a(x - 3)² + 6  

passes through the point (4, 4) means: if x=4 then f(x)=4

4 = a(4 - 3)² + 6  

4 -6 = a(1)² + 6 -6

-2 = a

Therefore the equation of parabla is:

                                  f(x) = -2 (x - 3)² + 6  

The vertex of a parabola is the maximum or the minimum point on the parabola.

The equation of the parabola is: [tex]\mathbf{y = -2(x -3)^2 + 6}[/tex]

The given parameters are:

[tex]\mathbf{Point = (x,y) =(4,4)}[/tex]

[tex]\mathbf{Vertex = (h,k) =(3,6)}[/tex]

The equation of parabola is:

[tex]\mathbf{y = a(x - h)^2 + k}[/tex]

Substitute values for x, y, h and k

[tex]\mathbf{4 = a(4 - 3)^2 + 6}[/tex]

[tex]\mathbf{4 = a(1)^2 + 6}[/tex]

[tex]\mathbf{4 = a + 6}[/tex]

Subtract 6 from both sides

[tex]\mathbf{a = -2}[/tex]

Substitute values for h, k and a in [tex]\mathbf{y = a(x - h)^2 + k}[/tex]

[tex]\mathbf{y = -2(x -3)^2 + 6}[/tex]

Hence, the equation of the parabola is:

[tex]\mathbf{y = -2(x -3)^2 + 6}[/tex]

Step-by-step explanation:

A = Rational numbers

B = Integers

C = Whole numbers

D = Natural numbers

E = Irrational numbers

11.  B

60/15 is a natural number because it equals 4 and is a positive integer

12. B, C, and D

An integer is a whole number meaning that because B. 42/6 = 7, C. 2√100 = 10, and D. 8 are all not fractions or decimals, they are integers.

Let, speed of 1st bicyclist is x.

So, speed of 2nd bicyclist is x-3 .

We know, relative speed when two objects moves towards each other :

[tex]v = x + ( x-3 )\\\\v = 2x - 3[/tex]

Now, distance travelled in 3 hours is (98-2) miles .

So,

[tex]2x-3 = \dfrac{96}{3}\\\\2x - 3 = 32\\\\2x = 35\\\\x = 17.5\ mph[/tex]

Therefore, speed of bikes are 17.5 mph and 14.5 mph.

Hence, this is the required solution.

Answer:

H

Step-by-step explanation:

H is the answer because in the simplest and easy way I can explain this is that it does have the same x in the table. If you look at F the x 0 repeats twice in the third and forth point. If you look at G the x -3 repeats twice in the first and second point. If you look at J the x 2 repeats twice in the first and forth point. The only answer choice does repeats any of the x's is H with the x's of -4, -2, -1, and 3. So with this being said H is the answer.

The y can repeat as a function just not the x.

Answer: = UwU

Step-by-step explanation:

Answer:

5u

Step-by-step explanation:

Simplifying

5u + -1u = u + 15

Combine like terms: 5u + -1u = 4u

4u = u + 15

Solving for variable 'u'.

Move all terms containing u to the left, all other terms to the right.

Add '-1u' to each side of the equation.

4u + -1u = 15 + u + -1u

Combine like terms: 4u + -1u = 3u

3u = 15 + u + -1u

Combine like terms: u + -1u = 0

3u = 15 + 0

3u = 15

Divide each side by '3'.

u = 5

Simplifying

u = 5

Answer:

1) To see whether it is a maximum or a minimum, in this case we can simply look at the graph. f(x) is a parabola, and we can see that the turning point is a minimum. By finding the value of x where the derivative is 0, then, we have discovered that the vertex of the parabola is at (3, −4).

[tex]\frac{65+83+93+x}{4}=85\\\\\\\frac{241+x}{4} = 85[/tex]

241 + x  = 85*4

241 + x = 340

       x = 340 - 241

x = 99

Notice that the denominator is a multiplied by 2 for each fraction.

1/1•2 = 1/2

1 /2•2 = 1/4

1/4•2 = 1/8

A bisector splits an angle into two equal angles.

The answer is the last one: it splits the angle into two congruent angles.

Answer: -4,-3

Step-by-step explanation:

You start at the point (1,4) on the coordinate plane. The first number is on the x-axis, which moves horizontally and is divided down the middle by the y-axis. The left side of the x-axis is negative, while the right side of the x-axis is positive. The second number is on the y-axis, which moves vertically and is divided in half by the x-axis. The upper half of the y-axis is positive, while the lower side of the y-axis is negative.

If you start at the point (1,4) then the x coordinate would be 1 and the y coordinate would be 4. So moving left by 5 units you would be subtracting 5 from the x coordinate. Similarly, by moving down seven units you would be subtracting 7 from the y coordinate.

Solve:

1 - 5 = -4

-4 is your x coordinate

4 - 7 = -3

-3 is your y coordinate

The coordinate (-4,-3) is your answer

Answer:

21/8

Step-by-step explanation:

3/8 x 7/1 = 21/8

Answer:

(21/8) (no parenthesis required)

or

2 and 5/8 (no "and" required)

Step-by-step explanation:

When you divide fractions, multiply the first number by the reciprocal of the second (2/3's reciprocal is 3/2 and 5/8's reciprocal is 8/5)

3/8 ÷1/7

= (3/8)*(7/1)

then multiply the numerators together and put them over the denominator

=21/8

= 2 and 5/8

Answer:

c = 2.4

p = 1.6

Step-by-step explanation:

Given:

5c+4p=18.40

2c+4p=11.20

-1(2c+4p=11.20)    <-- Distribute -1 so that you can cancel out p

-2c-4p=-11.20

    5c+4p=18.40

+  -2c-4p=-11.20      <-- Add/simplify like terms

    3c = 7.2              <-- Isolate c by dividing    

c = 2.4

Now that we have c, we can find p

5c+4p=18.40

5(2.4)+4p=18.40   <-- Sub in 2.4 for c

12+4p=18.40        <-- Combine like terms in one side

4p=6.4                 <-- Isolate p by dividing

p = 1.6
