Answer:
220 in2
Step-by-step explanation:
(10 * 5) * 2 = 100
(10 * 4) * 2 = 80
(5 * 4) * 2 = 40
cuz the bottom of the rectangle
100 + 80 + 40 = 220
Answer:
Step-by-step explanation:
the correct answer is 220 in I took the k12 math quiz just now and got 80% but this question was correct
B.) Drawing a 2 from a deck of cards, not replacing it, and then drawing another 2
C.) Rolling a die and getting 6, and then rolling it again and getting 6 again
D.) Drawing a king from a deck of cards, replacing it, and then drawing another king
Answer:
Step-by-step explanation:
If I'm understanding this correctly, your problem is as follows:
The area of a circle is given by the formula
The area of the circle is changing at a rate of . Find the rate of change of the radius, , when r = 8.
Assuming that is what you are asking, we will begin by finding the derivative of the area of a circle using implicit differentiation.
Filling in what we have:
which simplifies a bit to
Divide both sides by 16π to get:
The π's cancel leaving the rate of change of the radius as
inches per second
Let's solve this by using the quadratic formula:
Note that we only use the coefficients so a=12, b=-14, and c=-6.
Plug values in the quadratic equation:
And so by evaluating those values we obtain:
Now we have two answers which are our factors one where we add another where we subtract and so:
First factor:
Second Factor:
And so your factors are
meaning that those are your roots/x-intercepts.

Answer: m=6.2t, 148.8 miles
Step-by-step explanation:
to figure out the equation we do 93/15=6.2 and we make it into a equation which is m=6.2t. since we know the butterfly travels 6.2 per hour we do 6.2 x 24 = 148.8
sorry if it's wrong
