Answer:
1. 32
2. 4.7
3. 3
Step-by-step explanation:
4*8=32
6.5-1.8= 4.7
18/6=3 or 18 divided by 6 = 3
Answer: It is a composite number since it has more factors than just itself and 1.
Step-by-step explanation:
1x20=20
2x10=20
4x5=20
Answer:
a) 13 m/s
b) (15 + h) m/s
c) 15 m/s
Step-by-step explanation:
if the location is
y=x²+3*x
then the average velocity from 3 to 7 is
Δy/Δx=[y(7)-y(3)]/(7-3)=[7²+3*7- (3²+3*3)]/4= 13 m/s
then the average velocity from x=6 to to x=6+h
Δy/Δx=[y(6+h)-y(6)]/(6+h-6)=[(6+h)²+3*(6+h)- (6²+3*6)]/h= (2*6*h+3*h+h²)/h=2*6+3= (15 + h) m/s
the instantaneous velocity can be found taking the limit of Δy/Δx when h→0. Then
when h→0 , limit Δy/Δx= (15 + h) m/s = 15 m/s
then v= 15 m/s
also can be found taking the derivative of y in x=6
v=dy/dx=2*x+3
for x=6
v=dy/dx=2*6+3 = 12+3=15 m/s
Answer:
Step-by-step explanation:
If they can be rounded to 70 to the nearest 10s. Then they are from 65 to 74.
Their sum is 136.
If we use 136 divided by 2 we get 68.
Since they're distinct, so one can be 67 and one can be 69
Answer:
![\sqrt[5]{25x^{2}y^{4}z^{6} }](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B25x%5E%7B2%7Dy%5E%7B4%7Dz%5E%7B6%7D%20%7D)
Step-by-step explanation:
going to the 2/5 power is the the fifth root of a square. For fraction exponents going into radical form use the denominator as you root of and use the numerator as the exponent of the rest making sure to multiply any other exponents by that number and when there is no exponent treat it as having an exponent of one for the multiplying.
