Write and solve an equation of ratios:
5 *10^9 years 100 m
------------------- = --------------
5 * 10^3 yrs x
Reducing the first fraction,
100 m
10^6 = ----------
x
100 m
Solving for x, x = ------------- = 10^(-4) m, or [10^(-1)] * [10^(-3))]
10^6
this comes out to one tenth of 1 millimeter.
Say base1 = 26 and base2 = 12 then your height is 18.
1/2 (18) times ( 26+12)
So that's 9 times 38=342
342 squared is your answer
Answer:
60
Step-by-step explanation:
(2x+15)=135 They're corresponding angles so they equal/congruent
<u> -15 -15</u> Subtract 15 on both sides since you're looking for x
<u>2x</u> = <u> 120</u> Bring down the remains and subtract 135 from 15
2 2 Add 2 on both sides
x= 60 Divide.
Answer:
It is angle 4 because they make 90 degrees together. This is if there are choices for the problem.
It would be ∠4
Answer: The equations of the tangents that pass through
y = -x- 1 and
y = 11x -25
Step-by-step explanation: The gradient of the tangent to a curve at any particular point is given by the derivative of the curve at that point. So for our curve (the parabola) we have
y= x^2 +x
Differentiating wrt x we get:
dy/dx = 2x +1
Let P (a, B) be any generic point on the curve. Then the gradient of the tangent at P is given by:
