Answer:
3.712 x 10^8
Step-by-step explanation:
use the commutative property to reorder the terms
(5.8x 6.4) x (10^5 x 10^2)
multiply 5.8 x 6.4 = 37.12
add 5+2=8
37.12 x 10^7
write the number in scientific notation
3.712 x 10^8
that'sur answer
Answer: 5.8 x 10^5 =
6.4 x 10^2 =
Step-by-step explanation:
There is 5 10's because number of exponents are 5
so you multiply 5.8 by 10 10 10 10 10
The other is 6.4
multiply that by 10 10
But you can't multiply by all of that with one constant
So you answer the first one 10 x 10 x 10 x 10 x 10 = 100000
the other is 100
So now you multiply 5.8 by 100000
And multiply 6.4 by 100

C. Two vectors are said to be parallel if they point in the same direction or if they point in
opposite directions.
i. Are the vectors = < 1> and = <--1> parallel? Show your work and explain.
Type your response here:
ii. Are the vectors = <2, 3> and = <-3, -2> parallel? Show your work and explain.
Type your response here:
Answer:
Hey there,
The answer is below!!
Step-by-step explanation:
Knowing that those vectors start at the point (0,0) we can "think" them as lines.
As you may know, two lines are parallel if the slope is the same, then we can find the "slope" of the vectors and see if it is the same.
A) the vectors are: (√3, 1) and (-√3, -1)
You may remember that the way to find the slope of a line that passes through the points (x1, y1) and (x2, y2) is s = (y2 - y1)/(x2 - x1)
Because we know that our vectors also pass through the point (0,0)
then the slopes are:
(√3, 1) -----> s = (1/√3)
(-√3, -1)----> s = (-1/-√3) = (1/√3)
The slope is the same, so the vectors are parallel.
Part B:
The vectors are: (2, 3) and (-3, -2)
the slopes are:
(2, 3) -----> s = 3/2
(-3, -2)----> s = -2/-3 = 2/3
the slopes are different, so the vectors are not parallel.

Solve the equation.
Answer:
log 12-2 gets u 10+3 GET U 13Step-by-step explanation:
Roger gets $40 per day as wages and $4.50 as commission for every pair of shoes ne sells in a day. His daily
earnings goal is $112.
Write an equation to determine how many pairs of shoes, D, Roger must sell in a day to meet his daily earnings
goal
Answer:
Equation : y = 4.50D + 40
Number of pairs = 16
Step-by-step explanation:
It is given that:
Per day wage of Roger = $40
Commission on per pair of shoes = $4.50
Daily goal = $112
Number of pairs of shoes = D
Total earning = y
y = 4.50D + 40
112 = 4.50D + 40
4.50D = 112 - 40
4.50D = 72
Dividing both sides by 4.50
[tex]\frac{4.50D}{4.50}=\frac{72}{4.50}\\D = 16 \\[/tex]
Therefore,
Equation : y = 4.50D + 40
Number of pairs = 16

Answer:
The slope is -2.
Step-by-step explanation:
1) The equation for a slope is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex].
2) Plug in x and y values into the equation. I plugged in (3,0) and (8,-10) into the equation.
3) You end up with: [tex]\frac{-10 -0}{8-3}[/tex], which simplifies down to [tex]\frac{-10}{5}[/tex], which equals -2.
Hope this helps! Feel free to give me Brainliest if you feel this helped. Have a good day, and good luck on your assignment. :)

Answer:
15 degrees
Step-by-step explanation:
So you know that the sum of the two angles is 90 degrees, so you can make an equation:
[tex]3x + 45 =90[/tex]
Then, solve:
subtract 45 from both sides
[tex]3x = 45[/tex]
divide both sides by 3
[tex]x = 15[/tex]
This means that x = 15 degrees
Answer:
The answer is 15 degrees.
Step-by-step explanation:
1) Do you see the little square symbol at the bottom right corner? That represents that the angle is a right angle, or a 90 degree angle, in other words.
2) If you know that the first part of the angle is 45 degrees, as it is already labeled, then subtract 90 degrees - 45 degrees = 45 degrees, which is the angle that is left.
3) Set 3x equal to 45 degrees, and solve.
4) So, the equation is 3x = 45; divide by 3 on both sides to get x = 15 degrees.

What is the value of x?
Enter your answer in the box.
Answer:
x = 111º
Step-by-step explanation:
In a heptagon, (A polygon with 7 sides, and therefore 7 angles), the sum of the interior angles is always 900º (just like the sum of all interior angle in a quadrilateral is always 360º). So you can add up all of the interior angles, and subtract them from 900º.
900º - (158º + 120º + 126º + 125º + 121º + 139º) = 111º
