Answer:
140
Step-by-step explanation:
so where trying to find the unknown total of coins so where gonna call that x
then we will make an equation 5% * x= 7
then to make it easier to solve we will convert 5% to a decimal .05
and finally to find the answer we will divide both sides by .05
this gives us x= 140 which is the answer
If you don’t have any of the angles, you would use the law of cosines to find an angle.
Answer:
y = -2x + 1
Step-by-step explanation:
Parallel lines are two lines that have the same plane and slope but never intersect.
Answer:
f'(x) = cos(3x^2)(6x)
Step-by-step explanation:
(d/dx)(sin u) = cos(u)·du/dx . . . . . chain rule
For f(x) = sin(3x^2), this means ...
f'(x) = cos(3x^2)(6x)
A relation is a set of inputs and outputs, often written as ordered pairs (input, output). We can also represent a relation as a mapping diagram or a graph. For example, the relation can be represented as:
