Answer:

Solution of given quadratic equation is

[tex]$ (\frac{8i}{3}, -\frac{8i}{3} ) $[/tex]

Step-by-step explanation:

The given quadratic equation is

[tex]9x^2 + 64 = 0[/tex]

The general form of the quadratic equation is given by

[tex]ax^2 + bx + c = 0[/tex]

Comparing the general form with the given quadratic equation

[tex]a = 9\\b = 0\\c = 64[/tex]

The solutions of the quadratic equation is given by

[tex]$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$[/tex]

Substitute the values of a, b and c

[tex]$x=\frac{-0\pm\sqrt{0^2-4(9)(64)}}{2(9)}$[/tex]

[tex]$x=\frac{\pm\sqrt{-2304}}{18}$[/tex]

[tex]$x=\frac{\pm48i}{18}$[/tex]

[tex]$x=\frac{\pm8i}{3}$[/tex]

[tex]$x=\frac{8i}{3}$[/tex]

and

[tex]$x=-\frac{8i}{3}$[/tex]

Where i represents iota which means that the given quadratic equation has complex roots.

So the solution of given quadratic equation is

[tex]$ (\frac{8i}{3}, -\frac{8i}{3} ) $[/tex]

The factored form of the given quadratic equation is

[tex]$ (x+ \frac{8i}{3}) (x- \frac{8i}{3}) = 0 $[/tex]

Answer:

There is a local maximum at the point (-1,6), therefore, for x = -1

Step-by-step explanation:

Notice that the function adopts values smaller than 6 to the left of x = -1, and to the right of it:

(-3, -2), (-2, 0) to the left of x = -1 where the function's value is 6

and (0, 0), and (1, -2) to the right of x = -1

therefore, it looks like (-1, 6) is a maximum, that is for x = -1, where the function renders a value of 6.

Answer:

D is the correct answer

Answer:

C. x+2

Step-by-step explanation:

a factor of polynomial is where polynomial = 0

in this case it's -2 so (x+2)

Answer:

Step-by-step explanation:

In circle C, RT= 6, RS = 10, and QT= 3. What is the length of line segment PQ?

In circle C, RT= 6,

RS = 10, and

QT= 3.

What is the length of line segment PQ?

[tex](RT) (RS) = (QT) (PQ)[/tex]

so plug that in

[tex](6)(10)=(PQ)(3)[/tex]

[tex](6)(10)=(PQ)(3) \\\\60=(PQ)(3)\\\\PT=\frac{60}{3} \\\\PQ=20[/tex],

Answer: always

Step-by-step explanation:

A right triangle is a kind of triangle with one right angle.

A theorem of right triangle says that :-

Hence, the statement "The altitude to the hypotenuse of a right triangle is the geometric mean between the segments on the hypotenuse."  is always true.

Thus , the correct answer is "always".

Your answer should be always :)

(I know this has already been answered, but it can be reassuring to some people that the answer is correct ^-^)

Answer:

84ft

Step-by-step explanation:

6 * 14 = 84

Answer:

14%

Step-by-step explanation:

first, you would have to find how many skittles there are in total. You would add the red, blue, green, and purple skittles together and get 72. Next you would take the number of red skittles (10) and put it over the number of total skittles (72) and get the fraction 10/72. Lastly divide 10 by 72 and get the decimal .13888889 which would round up to .14 move the decimal over 2 places and get 14%

hope this helped :)

Answer: B

Step-by-step explanation:

If there is a change in something it normal means you subtract 1 number from another.

In this case the two values were 5 and -11.

At midday for answer b, it was 5  and at midnight it -11. It then wants to know the change in temperature which would result in an expression of 5-(-11).

Answer:

Measure of the side, x = 5.25 units

Step-by-step explanation:

Figure B is a scale image of figure A.

That means figure B is an image and figure A is a pre-image.

Scale factor for the dilation from figure A to figure B = 1.75

Scale factor = [tex]\frac{\text{Side of image B}}{\text{Side of pre-image A}}[/tex]

             1.75 = [tex]\frac{x}{3}[/tex]

                  x = 1.75 × 3

                  x = 5.25 units

Therefore, measure of the side figure B is 5.25 units.

Answer:

(x – 1)(x^2 + x + 1) = x^3 - 1.

(x + 4)(x^2 - 4x + 16) = x^3 + 64.

Step-by-step explanation:

The identities are:

(a - b)(a^2 + ab + b^2) = a^3 - b^3   and

(a + b)(a^2 - ab + b^2) = a^3 + b^3

Answer:

x = 0 or x = 4

Step-by-step explanation:

x² + y² = 25 and y = -2x + 5

Here,

x² + y² = 25 ...(1)

Now,

Put the value of y = -2x + 5 in equation (1)

we get,

x² + (-2x + 5)² = 25

x² + {(-2x)² + 2(-2x) (5) + (5)²} = 25

x² + {4x² - 20x + 25} = 25

x² + 4x² - 20x + 25 = 25

5x² - 20x = 25 - 25

5x² - 20x = 0

5x(x - 4) = 0

5x = 0 or x - 4 = 0

x = 0/5 or x = 4

x = 0 or x = 4

Answer:

x = 0, x = 4

Step-by-step explanation:

the total is 5

the red and orange equals to 2

2/5 times 120

240/5

Answer:

First parentheses

7-3=4

4^3 / 4 x 2

Next exponents

do 4^3

4 x 4 x 4 = 64 x 4 = 256

256 / 4 x 2 is left

256 / 4 = 64

64 x 2 = 128

128

Answer:

x = 7.5

Step-by-step explanation:

5/6 = 10/2x-3

Solve using cross products

5 ( 2x-3) = 6*10

Divide each side by 5

2x-3 = 6*10/5

2x-3 =12

Add 3 to each side

2x-3+3 = 12+3

2x =15

Divide each side by 2

2x/2 = 15/2

x = 7.5

Answer:

the answer will be x=-9

Step-by-step explanation:

-5(x+6)=15

-5x-30=15

-5x=15+30

-5x=45

×=-9

Answer:

[tex]x=-9[/tex]

Step-by-step explanation:

[tex]-5(x+6)=15[/tex]

Use the distributive property.

[tex]-5x-30=15[/tex]

Add [tex]+30[/tex] on both sides of the equation.

[tex]-5x=15+30[/tex]

[tex]-5x=45[/tex]

Divide [tex]-5[/tex] on both sides of the equation.

[tex]x=45/-5[/tex]

[tex]x=-9[/tex]

Answer:

1 not rectangle

2 not rectangle

3 rectangle

Answer: 12 inches

Step-by-step explanation:

Vol = 1/3 x b x h

240 = 1/3 x b x 15

b = 240/5 = 48 in = area of triangle base

Area = 1/2 x b x h

48 = 1/2 x 8 x h

h = 48/4 = 12 inches
