Answer:
137
Step-by-step explanation:
180-43=137
the 180 comes from when you combine angles 1 and 2 (because they form a straight line). you subtract angle 1 and you will get angle 2. since angle 2 and 4 are across from each other, that means they are the same degree. so the answer would be 137
Answer:
Step-by-step explanation:
So, the function, P(t), represents the number of cells after t hours.
This means that the derivative, P'(t), represents the instantaneous rate of change (in cells per hour) at a certain point t.
C)
So, we are given that the quadratic curve of the trend is the function:
To find the <em>instanteous</em> rate of growth at t=5 hours, we must first differentiate the function. So, differentiate with respect to t:
Expand:
Move the constant to the front using the constant multiple rule. The derivative of a constant is 0. So:
Differentiate. Use the power rule:
Simplify:
So, to find the instantaneous rate of growth at t=5, substitute 5 into our differentiated function:
Multiply:
Subtract:
This tells us that at <em>exactly</em> t=5, the rate of growth is 51.72 cells per hour.
And we're done!
Answer:
x=-7
Step-by-step explanation:
Since they're both equal to y, you can make them equal to each other
Answer:
$7,500
Step-by-step explanation:
2,500 - 1000 = 1500
1500 * 5 = 7,500
