What is the value of the function at x=-2

Y=-4
Y=0
Y=2
Y=3

Answer:

(x-rooot1)(x-root2)

Step-by-step explanation:

a quadratic ax²+bx+c=0 can be factor as those 2 pharanthesis

(x-rooot1) (x-root2)=0

and you can find the roots by making each parenthesis equal to 0 because of the zero product rule

x-root1 = 0, x=root1

x-root2 =0, x=root2

The correct answer is 9 or option D:)

bro this is eazy if i get it right give me brainliest

Answer: 9

Answer:

Remainder → (76)

Step-by-step explanation:

Given function;

f(x) = x² - 5

f(x) = x² + 0.x - 5

We have to divide this function by expression (x + 9).

x + 9) x² + 0.x - 5 (x - 9

        x² + 9x

             - 9x - 5  

             - 9x - 81

                      76

Therefore, by dividing the function 'f' by (x + 9) remainder is (76).

Answer:

Step-by-step explanation:

7 + (-5)= 2

The value of the expression 17[cos(315°) + isin(315°)] will be (17√2 / 2) – (17√2 / 2)i. Then the correct option is A.

The connection between the lengths and angles of a triangular shape is the subject of trigonometry.

The rectangular form of 17(cos(315°) + isin(315°)).

We know that the value of cos 315° and sin 315°.

[tex]\sin 315^o = \dfrac{-1}{\sqrt2}\\\cos 315^o = \dfrac{1}{\sqrt2}[/tex]

Then the value of the expression will be

⇒ 17[(1/√2) – (1/√2)i]

⇒ (17√2 / 2) – (17√2 / 2)i

Then the correct option is A.

Answer:

'The difference between six, and a number divided by four is sixteen' will be translated into an equation such as:

Step-by-step explanation:

Let 'n' be the number

The difference between six and a number 'n' is written in an algebraic expression such as:

[tex]6 - x[/tex]

Dividing 6-x by 4 will become:

so the sentence the difference between six, and a number divided by four is sixteen will become:

Therefore, 'The difference between six, and a number divided by four is sixteen' will be translated into an equation such as:

Step-by-step explanation:

We can recognize this equation as a linear equation, which is given by the following formula:

[tex]y=mx-b[/tex], where m is the slope and b is the y-intercept.

Thus, we see that 3 is the slope, and 9 is the y-intercept.

The sum would end us as: 2.33333333

Answer:

7 1/2 teaspoons of vanilla

Step-by-step explanation:

From the above question,

The whipped cream for 1 pie contains

1 1/4 teaspoon of vanilla

Hence:

1 pie = 1 1/4 teaspoon of vanilla

6 pies = x

Cross Multiply

x = 6 × 1 1/4

x = 6 × 5/4

x = 30/4

x = 7 2/4

x = 7 1/2 teaspoons of vanilla

Hence: If K makes 6 pies and covers them with whipped cream, he would be needing 7 1/2 teaspoons of vanilla

Answer:

[tex]Sleeping = 10[/tex]

[tex]Eating = 5[/tex]

[tex]Hiding =25[/tex]

Step-by-step explanation:

Given

[tex]Turkey = 40[/tex]

[tex]Sleeping = \frac{1}{4}[/tex]

[tex]Eating = \frac{1}{8}[/tex]

[tex]Hiding = \frac{5}{8}[/tex]

Required

Determine the number in each category

To solve this, we simply multiply each fraction by the total number of turkey:

[tex]Sleeping = \frac{1}{4} * 40[/tex]

[tex]Sleeping = \frac{40}{4}[/tex]

[tex]Sleeping = 10[/tex]

[tex]Eating = \frac{1}{8} * 40[/tex]

[tex]Eating = \frac{40}{8}[/tex]

[tex]Eating = 5[/tex]

[tex]Hiding = \frac{5}{8} * 40[/tex]

[tex]Hiding = \frac{200}{8}[/tex]

[tex]Hiding =25[/tex]

Answer:

C=25n+4300

Step-by-step explanation:

Given that,

Last year, Pinwheel Industries introduced a new toy. It cost $4 ,300 to develop the toy and $25 to manufacture each toy.

We need to write a linear equation in the form C=mn+b that gives the total cost, C, to produce n of these toys.

Here, m will be cost for each toy and b is the cost to develop each toy. So,

C=25n+4300

Hence, this is the required solution.

Answer:

A. Move the decimal point to the left

Step-by-step explanation:

Given that:

The scientific notation = 10⁻¹⁰

Let recall;

That the standard notation usually took the form of an inverse:

For example;

Let say 10⁻¹ will be [tex]\dfrac{1}{10}[/tex] in scientific notation;

SO, [tex]\dfrac{1}{10} = 0.1[/tex]

Now; we are given 10⁻¹⁰ as a scientific notation,

To standard notation, we get:

[tex]10^{-10} = \dfrac{1}{100}[/tex]

= 0.01

Thus, it is true to say that the decimal point will be moved to the left side when converting a number from scientific notation to standard notation if the power of 10 is  -10.
