Answer:
What.
Step-by-step explanation:
WHAT.!?
well none of the answer choices match up with all these statements ...
C. it only matches up with the y-intercept given
D. it matches with the y-intercept, and the x- intercept is not quite on the 1
*but i would say C is the closest, because it has an x-intercept of -1 and the maximum point is at (1,4) ... which are the same with the given statements except that they have opposite signs, but yeah i have no clue*
Answer:
4845 combinations
Step-by-step explanation:
Whenever there is a selection of some elements from a certain group, there are several ways to do so. There are different combinations from the group which can be selected. The concept of combination means that there are certain number of elements to be selected from the group and there is no importance given to the order of the selection. The total number of students are 20, and 4 out of them have to be selected. It can be clearly seen that the order of selection does not matter, therefore the formula to be used is:
Combinations = 20C4 = (20*19*18*17)/(4*3*2*1) = 4845.
So the correct answer is 4845 combinations!!!
This is 1 whole because you have to make the equation 1/4+9/12 and then you have to find the Lowest Common Denominator (LCD) then it will look like 3/12+9/12= 12/12=1 whole Hope that helped
To determine the circumference and area of these circles, we must use the proper formulas.
For circumference : 2PiR (or PiD, which Pi = 3.14).
For area: PiR^2
Since we have the radius, let's get to solving!
The first circle (Circle1):
Our radius is 8cm, so let's work for it's circumference. Using our formula, we will multiply 8 by 2 by 3.14.
16 x 3.14 = 50.24.
Circle1's circumference is 50.24cm^2.
Now let's do the area for Circle1.
The radius, 8, squared is (8x8) 64.
64 x 3.14 = 200.96 cm^2.
The area for Circle1 is 200.96cm^2.
Now let's work with Circle2 (second circle).
The radius for that circle is 5cm.
Let's use our circumference formula.
5 x 2 x 3.14 = 10 x 3.14 = 31.4cm^2,
Our circumference for Circle2 is 31.4cm^2.
Now let's do the area for Circle2.
3.14 x 5^2.
25 x 3.14 = 78.5cm^2.
Our area for Circle2 is 78.5.
Let's compare our circumferences and our areas.
Circle1 to Circle 2's Circumference:
50.24:31.4
If we were to divide 50.24 by 31.4 we'd get 1.6.
Circle1 to Circle2's Area: 200.96:78.5.
If we were to divide 200.95 by 78.5 we'd get 2.56.
The circles are NOT similar.
