hi <3

standard form is written in the form a x 10^n

where a is a number between 1 and 10

in this case, you would get 4.25 x 10^12

hope this helps :)

Step-by-step explanation:

This question is incorrect.

Answer:

x = 3/2

Step-by-step explanation:

5x-(x+4)=2

5x - x - 4 = 2

4x = 6

x = 6/4

x = 3/2

We have that the amount of people that makes between $39,000 and $57,000

[tex]X=28 People[/tex]

For normal distribution, P(X < A) = P(Z < (A - mean)/standard deviation)  

Mean = $48,000  

Standard deviation = $9000  

P(Person will have salary less than

[tex]P(39,000 < X < 57,000) = P(X < 35,000)-P(Z < (57,000 )[/tex]  

[tex]=P(Z < (57,000 - 48,000)/9,000) - P(Z < (35,000 - 48,000)/9,000)[/tex]  

[tex]= P(Z < 1) - P(Z < -2)\\\=0.1587-0.0228[/tex]

Option B. Here Adam Ct. is perpendicular to Betha Dr. and Charles. So, St. Bertha Dr. || Charles St. Since they are parallel to each other

Answer: Bertha Dr. || Charles St.

Step-by-step explanation:

Parallel lines are lines in a plane that do not meet; that is, two straight lines in a plane that do not intersect at any point are said to be parallel.

A line is said to be perpendicular to another line if the two lines intersect at a right angle.

Adam Court is perpendicular to Edward Road.

Bertha Drive is parallel to Charles St.

Dana Lane is perpendicular to Edward Road.

Matrix operations includes the addition, multiplication and subtraction of matrices

The correct option for the matrix that can be used to represent B is option D)

[tex]D) = \left[\begin{array}{rrr}6&-3&-6\\5&9&5\end{array}\right][/tex]

The reason the above option is correct is as follows:

From the graph, we have that the coordinates of the preimage are;

(-6, 5), (-3, 9), and (6, 5)

The coordinates of the preimage in matrix form is given as follows;

[tex]\left[\begin{array}{rrr}6&-3&-6\\5&9&5\end{array}\right][/tex]

The coordinates of the image are;

(-6, -5), (-3, -9), and (6, -5)

The coordinates of the image in matrix form is given as follows;

[tex]\left[\begin{array}{rrr}6&-3&-6\\-5&-9&-5\end{array}\right][/tex]

The above image matrix can be obtained from the primage matrix as follows:

[tex]\left[\begin{array}{rrr}1&0\\0&-1\end{array}\right]\left[\begin{array}{rrr}6&-3&-6\\5&9&5\end{array}\right] = \left[\begin{array}{rrr}6&-3&-6\\-5&-9&-5\end{array}\right][/tex]

Which is of the form AB = C

Where;

[tex]A = \left[\begin{array}{rrr}1&0\\0&-1\end{array}\right][/tex]

[tex]B = \left[\begin{array}{rrr}6&-3&-6\\5&9&5\end{array}\right][/tex]

[tex]C = \left[\begin{array}{rrr}6&-3&-6\\-5&-9&-5\end{array}\right][/tex]

Therefore, the matrix that could represent B is [tex]\left[\begin{array}{rrr}6&-3&-6\\5&9&5\end{array}\right][/tex] which is option D)

Step-by-step explanation:

The angle = less that 90 degrees so it has to be 80

Answer:

80 degrees

Step-by-step explanation:

because it has not yet made it to 90 degrees yet so it is 80 degrees

Write 97 as 90 + 7

then, 5 x 97 ---> 5 (90 + 7 )

5 (90 + 7 ) = ( 5 x 90 ) + ( 5 × 7 )

i took the test 1.13 Quiz: Distance on a Number Line

The length of points joining points 234 and -413 will be 647 in the number line.

In mathematics, a number line is a straight line containing numbers arranged at equal segments or periods throughout its duration.

In another word, a number line is basically a line in which infinite numbers have been written in ascending order or increasing order.

A horizontal number line is the most common representation and can be extended infinitely in any direction.

The point -413 will mark 413 distance from 0

So,

Distance from -413 to 234 = Distance from -413 to 0 + 0 to 234

Distance from -413 to 234 = 413 + 234 = 647

Hence "The length of points joining points 234 and -413 will be 647 in the number line".

A line can be divided in proportions using ratios. The point at which a line is divided in ratios is calculated using: [tex][\frac{mx_2+ nx_1}{m+n},\frac{my_2+ ny_1}{m+n}][/tex]

Given that:

[tex]RS : ST = 5 : 1[/tex]

The coordinates of RT are not given. So, I will solve using a general explanation.

When a line is divided into ratios, the point (S) at which the line is divided is calculated using the following line ratio formula:

[tex]S = [\frac{mx_2+ nx_1}{m+n},\frac{my_2+ ny_1}{m+n}][/tex]

Assume the coordinate of R and T is:

[tex]R = (1,6)\\T = (7,2)[/tex]

[tex]RS : ST = 5 : 1[/tex] means:

[tex]m:n = 5:1[/tex]

So, point S is:

[tex]S = [\frac{5\times 7+ 1 \times 1}{5+1},\frac{5 \times 2+ 1 \times 6}{5+1}][/tex]

[tex]S = [\frac{36}{6},\frac{16}{6}][/tex]

[tex]S = [6,\frac{8}{3}][/tex]

Hence, if the coordinates of R and T are:

[tex]R = (1,6)\\T = (7,2)[/tex]

And the line ratio is:

[tex]m:n = 5:1[/tex]

The coordinate of S is:

[tex]S = [6,\frac{8}{3}][/tex]

Semi-monthly means you get paid twice a week. We will find out the net pay in 2 weeks to see how much pays better.

Explanation:

Job A pays $15 an hour and whoever is working works 40 hours a week. We can multiply to find how much he/she earns in 2 weeks.

15 * 40 * 2 = $1,200

Job B pays $1,375 semi monthly which means that he/she got paid that much money in 2 weeks.

Answer:

Job B pays better.
