Answer:
the answer should be -4
Step-by-step explanation:
-4 squared would be 8. 3 multiplied by -4 would be -12. 8 + -12 = -4. -4 + 4 = 0
Do parenthesis first (4)
Then, do the division 8/2 = 4
Then multiply 4 and 4 which will be 16
Add 6 to 16 and you get 22
Answer:
The fifth term is 620
Step-by-step explanation:
y=40×(-2)^(n-1)
The 5th terms means n=5
y = 40 * (-2) ^ (5-1)
= 40 * (-2) ^4
= 40 * (16)
= 640
Answer:
4 1/2
Step-by-step explanation:
2/3 of 6 3/4 = 4 1/2
because "of" in math means multiply
so 2/3 x 6 3/4 = 4 1/2
First you have to write down the formula on how to get the circumference of the circle (C = 2pi * Radius) and the Area of the circle which is (A=Pi*Radius^2). In getting the radius you need to transform the formula of the circumference by making the radius to be the unknown variable so it would become(R=C/2pi), after that you need to replace the radius in the formula of the area by the transformed formula of the circumference and you will come up of the formula of (A=Pi(C/2pi)^2).
