Yes, 7 x [tex]10^{-3}[/tex] in standard form is 0.007mm

8 x [tex]10^{-5}[/tex] in standard form is 0.00008 mm.  The mask will catch particles that are much smaller than 0.007 in diameter.

Step-by-step explanation:

The roots of the function f(x) = [tex]x^2+2x-1[/tex] are

x = [tex]-1+\sqrt{2}[/tex]

x = [tex]-1-\sqrt{2}[/tex]

The function is given f(x)=  [tex]x^2+2x-1[/tex]

The roots of given function will be at f(x) = 0

Substitute the value in the equation

[tex]x^2+2x-1[/tex] =0

Here to find the roots of the function, we have to use the quadratic formula in the given function

Roots of the function = [tex]\frac{-b+/-\sqrt{b^2-4ac} }{2a}[/tex]

From the given function the values of

a = 1

b = 2

c = -1

Substitute the values in the quadratic formula and find the roots of the function

= [tex]\frac{-2+/-\sqrt{2^2-4(1)(-1)} }{2(1)}[/tex]

= [tex]\frac{-2+/-\sqrt{4+4} }{2}[/tex]

= [tex]\frac{-2+/-2\sqrt{2} }{2}[/tex]

The roots of the given functions are

x = [tex]-1+\sqrt{2}[/tex]

x = [tex]-1-\sqrt{2}[/tex]
Hence, the roots of the function f(x) = [tex]x^2+2x-1[/tex] are

x = [tex]-1+\sqrt{2}[/tex]

x = [tex]-1-\sqrt{2}[/tex]

The area of the triangle in the image is 10 square units, thus, option C is the correct one.

For a triangle of height H and a base B, the area is given by:

A = H*B/2.

In the image we can see that the base of the triangle goes from (0, 0) to (5, 0), then the length of the base is 5 units.

While the height goes from (0, 0) to (0, 4), so the height is 4 units.

Then the area will be:

A = (4 units)*(5 units)/2 = (20 square units)/2 = 10 square units.

The area is 10 square units.

a. The complete table for the ordered pairs that are solutions to y = x³ - 4 is

x             y

-1            -5

0            -4

1             -3

2            4

b. The graph of the equation is shown below

From the question, we are to complete the given table of ordered pairs that are solutions to the given equation.

The given equation is

y = x³ - 4

Now, we will determine the values of y for the given values of x

When x = -1

y = x³ - 4

y = (-1)³ - 4

y = -1 - 4

y = -5

(-1, -5)

When x = 0

y = x³ - 4

y = (0)³ - 4

y = 0 - 4

y = -4

(0, -4)

When x = 1

y = x³ - 4

y = (1)³ - 4

y = 1 - 4

y = -3

(1, -3)

When x = 2

y = x³ - 4

y = (2)³ - 4

y = 8 - 4

y = 4

(2, 4)

Thus,

The table is

Step-by-step explanation:

Slope of a line is given by:
[tex]\medium \text{$\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}$}[/tex]

where (x₁, y₁) and (x₂, y₂) are two points on the line

This is commonly referred to as rise/run

Given the two points (6, 1) corresponding to (x₁, y₁) and (9, j) corresponding to (x₂, y₂)

[tex]\text{Slope = }\dfrac{\ensuremath{j}-1}{9-6}=\dfrac{j-1}{3}[/tex]

But we are given the slope as 1/3

So we get
[tex]\dfrac{j-1}{3} = \dfrac{1}{3}[/tex]

Multiplying by 2 on both sides gives us:

j - 1 = 1

Adding 1 to both sides gives us

j - 1 + 1 = 1 + 1

j = 2

The inches of ribbon that Anais use to trim the curtains is 12 inches.

From the information, Anais bought 2 1/2 yards of ribbon and then he had 1 feet 6 inches of ribbon left after trimming some curtains.

It should be noted that 12 inches = 1 feet

Therefore, the inches that will be left will be:

= 2 1/2 - 1 6/12

= 2 1/2 - 1 1/2

= 1 feet

The percent increase in her salary resulted from her promotion is 6.67%.

The annual salary of Marisol as an engineer = $75000.

After, the promotion salary of Marisol as an engineer = $80000.

We have to find the increment in her salary after promotion in percentage.

Before finding the increment in percentage we find the total increment in dollar in her salary after promotion.

Total increment in dollar = Salary after Promotion − Salary before Promotion

Total increment in dollar = $80,000 − $75,000

Total increment in dollar = $5000

As we know that we can find the percentage by multiplying the required number by 100 because percentage is the ratio with 100.

So, the increment in salary after promotion in percentage.

% increment = (Total increment/Salary before) * 100

% increment [tex]= (\frac{5000}{75000})*100[/tex]

% increment = 0.0667 * 100

% increment = 6.67%

The number line that correctly compares √24 and 4.256 is number line C.

A number line can be defined as a type of graph with a graduated straight line which contains both positive and negative numbers (numerical values) that are placed at equal intervals along its length.

This ultimately implies that, a number line can be used for the comparison of two or more numbers such as √24 and 4.256. Also, a number line typically decreases in numerical value towards the left and increases in numerical value towards the right.

Taking the square root of √24, we have:

√24 = 4.899

In this context, we can reasonably and logically deduce that 4.899 is greater than 4.256 (4.899 > 4.256) and would be placed at the right hand side of the number line and further from 4.899 as shown in number line C in the image attached below.

In math, addition is the process of adding two or more integers together. Addends are the numbers that are added, while the sum refers to the outcome of the operation.

Given the depth on the first day is 26 ½ feet.

Depth on the second day = 9½ feet more than on the first day i.e. 9½ feet + depth on the first day

This implies, depth on the second day = 9½ + 26 ½

We can see that the ration of the length of the bigger rectangle  to the length of the smaller rectangle is 15/9 = 5/3  

Therefore the ratio of the width of the bigger rectangle  to the width of the smaller rectangle must also be 5/3

Given width of big rectangle = 10 and that of small rectangle is x

We get

10/x = 5/3

Multiply by x both sides:
x ×   10/x   =   x × 5/3

10 = 5x/3

Multiply by 3 both sides

30 = 5x

5x = 30

Dividing by 5 both sides
5x/x = 30/5
x = 6 cm

Answer: No, this is not a function.

Functions exist when there are a unique set of x-values and each can match with a y-value. There cannot be a repeating x-value because this creates a discontinuity in the graph. You can have as many repeating y-values as you’d like as long as they each have a unique x-value and are not duplicate plot points.

Since x = 7 repeats in the domain of x-values, this cannot be a function.

In the coordinate plane shown we can say that the y-coordinate of point A is 3.

Let us now take the statement one by one and try to find out if they are true or false.

A. True. The y-coordinate for A is 3

B. False. Point D has x-coordinate of 5 and E has 6

C. True The x-coordinate for F is 7

D. True The ordered pair for point G is (8,6)

E. False. Point H names the ordered pair (9,10).

F. false point B is √34 units away from origin

G. True.

The coordinate plane is a two-dimensional surface created by combining two number lines. A single horizontal number line makes up the x-axis. The name of the vertical number line, which is the other number line, is the y-axis. The intersection of the two axes is the origin. The graphing of points, lines, and other objects can be done using the coordinate plane.

Step-by-step explanation:

Kevin is making potato casserole for a dinner party. He needs 2½ pounds of potatoes per guest. How many pounds of potatoes will he need for 6 guests?

15 pounds

6.5 pounds  

25 pounds

12.5 pounds

2.5lb × 6 guest = 15 pounds

Answer: 15 pounds of potatoes.

Step-by-step explanation:

Kevin will perform basic multiplication to find how many potatoes he needs for all of the guests. Since each person requires 2 1/2 pound of potatoes and there are a total of 6 guests, multiplying these two values will find the pounds of potatoes that are needed for all of the guests.

2 1/2 * 6 = 15 pounds of potatoes

Therefore, Kevin needs 15 pounds of potatoes to make potato casserole for everyone at the dinner party.
