The option that expresses the age of tree in scientific notation with the lowest level of precision would be A. 3 X 10 to the 3rd power. As it contains the fewest number of significant figures.
Here, Angles under a straight line would be equal to 180
So, 70 + 60 + y = 180
130 + y = 180
y = 180 - 130
y = 50
Now, x = y [ As they are vertically opposite angles ]
In short, Your Answer would be 50
Hope this helps!
Answer:
y = 15
Step-by-step explanation:
We need to solve for k
y = x
21 = 7k Divide both sides by 7 to solve for k
3 = k
y = xk
y = 5(3)
y = 15
68000. The reason this is the answer is because you have to move the decimal point to the right 3 times since it’s x3
Answer:
slope form = y= 3/4x -7
point slope= y-(-3) = 3/4(x-3) or y-(-4)= 3/4(x-4)
Step-by-step explanation:
slope form = y= mx + b
y = 3/4x - 7
point-slope form = y - y1 = m(x - x1)
step 1. Substitute a convenient value of x into your equation and solve for y (You're doing this to get the point x1,y1). Let's choose x=3. Yes, you could choose x=4.
y= 3/4x - 7
if you choose x = 3
y=3/4(3) - 7
y = 4 -7
y = -3
(x1,y1) = (3,-3)
if you choose x = 4l
y= 3/4(4) - 7
y = 3 - 7
y = -4
(x1,y1)= (4, -4)
step 2. Substitute the point you found , (x1, y1) , into the point slope formula.
if you choose x=3
y-y1=m(x-x1)
y-(-3) = 3/4(x- 3)
if you choose x = 4
y- y1 = m(x-x1)
y - (-4) = 3/4(x-4)
