Answer:
6 or -6
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
[tex]v^2 = 12^2 + 2(-3)(18)[/tex] [tex]v^2 = 144 + (-6)(18)[/tex] [tex]v^2 = 144- 108[/tex] [tex]v^2 = 36[/tex]Step 2: Take square root of both sides.
[tex]\sqrt{v^2} =[/tex] ± [tex]\sqrt{36}[/tex] [tex]v =[/tex] ± [tex]\sqrt{36}[/tex] [tex]v = 6[/tex] or [tex]-6[/tex]Therefore, the answer is 6 or -6.

Let (x1, y1) = (10, 30)
(x2, y2) = (50, 50)
Use the following slope formula:
m = (y2 - y1)/(x2 - x1)
m = (50 - 30) / (50 - 10)
m = 20/40 or 1/2
Therefore, the slope of the line is 1/2.

Step-by-step explanation:
sin θ = - 0.9419
θ = sin inverse - 0.9419
= sin^-1 ( - 0.9419 )

a submarine is located 358 feet below sea level. it ascends 169 feet. At what depth is the submarine now
Answers
Answer:
189
Step-by-step explanation:
Ascending means to go upwards. So, since it is below the surface heading upwards, you would subtract the amount of feet that it went up by from the depth it was previously at.
358, take away 169, is 189.

Write the equation of the line in fully simplified slope intercept form
Answers
Answer:
y = -x - 8
Step-by-step explanation:
I don't know what it means by "fully symplified", but this is how I would answer.
Hope this helps, and if not, I'm sorry!
Answer:
[tex]y=-x-8[/tex]
Step-by-step explanation:
Slope intercept form is in the general form
[tex]y=mx+b[/tex] such that [tex]m[/tex] is the slope of the line, and that [tex]b[/tex] is the y-intercept of that line.
The equation for slope can be denoted as any of those below
[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex] Where the y and x terms are from two ordered pairs
[tex]m=\frac{rise}{run}[/tex], such that rise is the vertical change in a line, and run the run is the horizontal change
Work!
In this case, since we are given nothing but a line, we should use [tex]m=\frac{rise}{run}[/tex]
Since the graph goes down by 1 for every 1 distance to the right, the change in rise of y (-1) divided by the run of x (1) means that [tex]m=-1[/tex]
We now have [tex]y=-x+b[/tex]
Since b is the y-intercept, according to the graph [tex]b=-8[/tex]
This leaves you with the final answer of [tex]y=-x-8[/tex]
Hope this helps! :)

Mr James gives £500 to his children Ally,
Barry and Cat in the ratio 2:3:5.
How much do they each receive?
Answers
Answers:
Ally gets 100 poundsBarry gets 150 poundsCat gets 250 pounds=====================================================
Work Shown:
x = some positive real number
2x = amount Ally gets
3x = amount Barry gets
5x = amount Cat gets
Note that the ratio 2x:3x:5x reduces to 2:3:5 after dividing all parts by x.
Add up the parts and you should get a sum of 500 pounds. Solve for x.
2x+3x+5x = 500
10x = 500
x = 500/10
x = 50
Based on that x value, we then can say:
2x = 2*50 = 100 pounds is what Ally gets3x = 3*50 = 150 pounds is what Barry gets5x = 5*50 = 250 pounds is what Cat getsAs a check, 100+150+250 = 500.
Also, note that the ratio 100:150:250 fully reduces to 2:3:5 after dividing all parts by the GCF 50.
Those two facts help confirm our answers.
