The required error in Caroline's quadratic equation in vertex form by completing the square is -2(x² - 6x + 9) - 9 - 15 is should be -18 in place of -9.

Given that,
To figure out the error made by Caroline in the calculation of a quadratic equation in vertex form by completing the square.

His calculation,
= -2x² + 12x - 15

= -2(x² - 6x) — 15

= -2(x² - 6x + 9) - 9 - 15-2(x - 3)²9 - 15
= -2(x - 3)² - 24

Correct calculation,
= -2x² + 12x - 15
= -2(x² - 6x) - 15

= -2(x² - 6x + 9) - 18 - 15
= -2(x - 3)² - 18 - 15
= -2(x - 3)² - 33

Thus, the required error in Caroline's quadratic equation in vertex form by completing the square is -2(x² - 6x + 9) - 9 - 15 is should be -18 in place of -9.

The expression for h in the information illustrated will be h = 2r.

It should be noted that the expression is given as:

2πr³ = πr²h

In this situation, the information is that we should make h the subject of the formula.

This will be:

2πr³ = πr²h

Divide both side by πr²

2πr³/πr² = πr²h/πr²

2r = h

Therefore h = 2r

Answer:

x = 5

Step-by-step explanation:

Change "minus a negative" to "plus a positive"

x - (-3) = 8

x + 3 = 8

Next, subtract 3 from both sides.

x + 3 - 3 = 8 - 3

x = 5

Check it!

x - (-3) = 8

5 - (-3) = 8

5 + 3 = 8

8 = 8 Check!

We can conclude that in the question, angle m∠ABC = 58°.

So,

∠EBD is 29° and line EB bisects ∠CBD.

Similarly, ∠CBD = 58° and line CB bisects ∠ABD

Hence, ∠ABC = 58° as ∠CBD is also 58° because common line BC bisects the angle ∠ABD.

Therefore, angle m ∠ABD = 58°.

The two numbers whose sum is 52 and the product is maximum are 26 and 26.

Finding the least common multiples of the denominator expressions can help. Then using the similar method as we use in the sum of fractions would give the sum of algebraic fractions.

We need to find the two numbers whose sum is 52 and the product is maximum.

So, the multiples of 52 are

2, 26, 4, 13,

So, here we can see that the sum of 26 to itself would be equal to 52.

26 + 26 = 52

The product is also maximum compared to others.

26 x 26 = 676

The value of QR when points P, Q, R and S are collinear is .13

We are given that:

Points P, Q, R and S are collinear points.

Also,

PS = 23

PR = 18

We need to find the value for QR.

Now, we have that PQ is congruent to RS.

So, This means that PQ = RS

This can also be written as:

PR - QR = RS

18 - QR = RS

Also,

PR + RS = PS

Substituting the values, we get that:

18 + ( 18 - QR ) = 23

18 - QR = 23 - 18

18 - QR = 5

The distance from the center of a circle to a point in the interior of a circle is always less than radius of the circle.

It is given that there is a point inside the circle.

We have to find that whether its distance from center of circle is sometimes, always, or never less than the radius of the circle.

What is the radius of a circle ?

The distance between the center of a circle and any point on the circle is called the radius of circle.

We know that ;

Radius is the distance between the center of a circle and any point on the circle.

Let's assume three points which are A, B, and C, where A is a point inside circle, B is a point on circle, and C is a point outside circle.

Also ;

O is the center of circle.

So ;

OA = the length of the line from center to point inside the circle.

OB = radius of the circle.

OC = the length of the line from center to the point outside the circle.

So ;

We can conclude that ;

OA<OB<OC.

or

The length of the line from the center of a circle to any point inside the circle will be always less than it's radius.

the correct statement is the first one.

The inverse of 6^2 is 6^(1/2), then 6^(1/2) is the square root of 6.

Well, this is just a notation thing.

We know the following property for exponents:

(a^n)^m = a^(n*m)

And we know that the square rooth is the inverse of the square power (exponent equal to 2) such that:

√x^2 = 2

Then if we define the square root as an exponent, let's say that is an exponent "a" we will have:

√x = x^a

Rewritting the above relation again, we can write:

√(x^2) = (x^2)^a = x^(2*a)

And we know that it must be equal to x, so we get:

x^(2*a) = x

This means that 2*a = 1

then a = 1/2

√x = x(1/2)

Then the correct statement is the first one.

The inverse of 6^2 is 6^(1/2), then 6^(1/2) is the square root of 6.

We are given that:

The measures of the rectangular painting are:

Length = 13 inches

Now, the frame is of uniform with around the corner.

So the new dimensions will be:

Length = 13 + x inches

Width = 20 + x inches.

Also, we are given that:

Perimeter = 98 inches

So, we get that:

Substituting the values, we get that:

98 = 2 (13 + x + 20 + x)

98 = 2( 33 + 2 x)

98 = 66 + 4 x
