Answer:
560x^3
Step-by-step explanation:
The formula is
(r + 1)th term of (a + x)^n = nCr a^(n-r)x^r
So 5th term = (4 + 1)th term
= 7C4 x^(7-4) (-2)^4
= 35x^3*16
= 560x^3
It’s (a) 104
You’ll just replace the letters for the values given (10 and 2) next solve the exponents add your results together and you to 104
Answer:
7(45)=7(40)+7(5)
Step-by-step explanation:
We need to represent 7(45) using the distributive property to simplify.
We can write 45 as 40+5
So it becomes,
7(45) = 7(40+5)
Distributive property is : a(b+c)=ab+ac
a=7, b = 40 and c = 5
7(40+5)=7(40)+7(5)
So, the correct option is (4).
Answer:
254.5 Inches Cubed
Step-by-step explanation:
Formula for Finding the Volume of a Cylinder:
The radius is 3 inches.
The height is three times the radius.
Multiply the radius by three to get the height.
The height is 9 inches.
Use the formula to find the volume.
The exact volume is 81 inches cubed.
≈ 254.47
254.47 ≈ 254.5
The volume of the cylinder should be about 254.5 inches cubed.
