Answer:
4 light years
Step-by-step explanation:
(2.4·10¹³ miles)/(6·10¹² miles/ly) = 0.4·10¹ ly = 4 light years

The applicable rule of exponents is ...
(a^b)/(a^c) = a^(b-c)
Answer:
y = 8x + 15
Step-by-step explanation:
Step 1: Find slope of perpendicular line
<em>Take the negative reciprocal of the 1st equation</em>
m = 8
y = 8x + b
Step 2: Find <em>b</em>
7 = 8(-1) + b
7 = -8 + b
b = 15
Step 3: Rewrite perpendicular equation
y = 8x + 15
Answer:
27.3 yards
Step-by-step explanation:
Since this triangle is a right triangle, this can be solved using the equation:
a^2 + b^2 = c^2
c^2 is the side opposite to the right angle (37)
So, you need to change the equation to where it is set equal to b^2.
Subtract a^2 on both sides.
b^2 = c^2 - a^2
Now, plug in the numbers you have.
b^2 = 37^2 - 25^2
Simplify.
b^2 = 1369 - 625
b^2 = 744
Now, to find b, take the square root of 744.
√744 = 27.3
