Answer:
Area of square=
Perimeter of square=a+a+a+a=4a units
Step-by-step explanation:
We have to give the formula for the area and perimeter of square where the side length is the independent variable and the area and perimeter is the dependent variable.
Let the side of square be a units which is independent variable.
As square is also a rectangle whose area is
Area of square=
Perimeter of square=a+a+a+a=4a units
Here, each two area and perimeter depend on the side of square implies area and square are dependent variable and side is independent.
Answer:
2520 ways
Step-by-step explanation:
We can solve this problem with 3 combinations:
First the teacher needs to give 3 fruit snacks to 10 students, so we have a combination of 10 choose 3: C(10,3) = 10! / (3! * 7!) = 120
Then, she needs to give 2 teddy grahams to 7 students (3 already got a snack), so a combination of 7 choose 2: C(7,2) = 7! / (2! * 5!) = 21
The, she gives the 5 granola bars to the other 5 students, so a combination of 5 choose 5: C(5,5) = 1.
Now we just need to multiply the combinations to find the result:
C(10,3) * C(7,2) * C(5,5) = 120 * 21 * 1 = 2520 ways
5x10+15-40(50)+40+10+24
50+15-40(50)+40+10+24
65-40=25+50=75+40=110+10=120+24=144
144 is your answer
Answer:
n = 2
Step-by-step explanation:
Take square,
Answer: f(x) = 64 * (3/4)^x
Step-by-step explanation: f(x)=ab^x
When x=0 f(x) = 64
64 = ab^0
b^0 =1 so
64 =a
f(x)=64 b^x
When x=1 f(x) = 48
48 = 64 *b
Divide by 64
48/64 =b
6/8 =b
3/4 =b
f(x) = 64 * (3/4)^x
