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).

What is the slope of у= 3х — 9​

Answers

Answer:

3

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 slope would be 3

When Jack started his job working for an industrial manufacturing company, he contributed $100
at the end of each month into a savings account that earned 1.2 % interest compounded monthly
for 8 years. At the end of the 8

Which describes the correct procedure when converting a number from scientific notation to standard notation if the power of 10 is -10? A .Move the decimal point to the left. B. Move the decimal point to the right. C. Move the decimal point to the right. D. Subtract 20 from the number.

Answers

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.

The difference between six, and a number divided by four is sixteen

Answers

Answer:

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

[tex]\frac{6\:-\:x}{4}=16[/tex]

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]

[tex]6-x[/tex] is obtained by 'subtracting, starting with 6'.

Dividing 6-x by 4 will become:

[tex]\frac{6\:-\:x}{4}[/tex]

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

[tex]\frac{6\:-\:x}{4}=16[/tex]

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

[tex]\frac{6\:-\:x}{4}=16[/tex]

Answers

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.

All 40 turkeys are in a pen. 1/4 are sleeping. 1/8 are eating, and 5/8 of them are hiding from the butcher. How many are sleeping How many are eating How many are hiding

Answers

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]

To make homemade whipped cream the recipe calls for 1 ½ C of heavy cream, 1 ¼ t of vanilla, and 1 t. of sugar. This amount of whipped cream would be enough to cover one pie. If K makes 6 pies and covers them with whipped cream, how many teaspoons of vanilla will he need?

Answers

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

What is trigonometry?

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

One hundred leaves from the same variety of African violet were selected. The leaves were then randomly assigned to 50 pots with type A soil and the remaining leaves were put into the 50 pots with type B soil. All of the pots were given the same amount of water and arranged in 10 rows of 10 pots near a window for light. The 50 pots with type A soil were placed closest to the window. At the end of two months, the pots with type A soil had the greatest number of pots with new growth, so the student concluded that soil type A was more effective that soil type B.Is this a valid conclusion?Yes, because the leaves were randomly assigned, this evenly distributed the variability in the leaves; therefore, type A soil is more effective than type B soil.Yes, because the amount of water and light were controlled, this may have reduced the variability in the response; therefore, type A soil is more effective than type B soil. No, because the pots with type A soil were closest to the window, they received more light, which may have led to the new growth.No, because only African violets were used, replication was not properly implemented; therefore, we cannot conclude that type A soil was more effective.
