Answer: The only factor of 13 and 80 is 1.
Step-by-step explanation:
Factors of 13: 1, 13.
Factors of 80: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80.
The only factor they have the same is 1.
Answer:
1
answer is D
Step-by-step explanation:
we must calculate it from this equation :
x³ -9x²+27x-25 then
![{2}^{3} -( 9 \times 4 )+ (27 \times 2) - 25 = 1](https://tex.z-dn.net/?f=%20%7B2%7D%5E%7B3%7D%20%20-%28%209%20%5Ctimes%204%20%29%2B%20%2827%20%5Ctimes%202%29%20-%2025%20%3D%20%201)
Answer with Step-by-step explanation:
We are given that
![f(x)=\mid x-9\mid](https://tex.z-dn.net/?f=f%28x%29%3D%5Cmid%20x-9%5Cmid)
when x<9
when ![x\geq 9](https://tex.z-dn.net/?f=x%5Cgeq%209)
LHD
![\lim_{x\rightarrow 9-}f'(x)](https://tex.z-dn.net/?f=%5Clim_%7Bx%5Crightarrow%209-%7Df%27%28x%29)
=![-\lim_{x\rightarrow 9-}(x-9)=-1](https://tex.z-dn.net/?f=-%5Clim_%7Bx%5Crightarrow%209-%7D%28x-9%29%3D-1)
RHD
![\lim_{x\rightarrow 9+}f'(x)](https://tex.z-dn.net/?f=%5Clim_%7Bx%5Crightarrow%209%2B%7Df%27%28x%29)
![=\lim_{x\rightarrow 9+}(x-9)=1](https://tex.z-dn.net/?f=%3D%5Clim_%7Bx%5Crightarrow%209%2B%7D%28x-9%29%3D1)
![LHD\neq RHD](https://tex.z-dn.net/?f=LHD%5Cneq%20RHD)
Hence, the function is not differentiable at x=9
Answer:
18 white flowers
Step-by-step explanation:
We are given ratio:
Red : White
2 : 3
If Sally used 12 red flowers, how many white flowers will she use?
Let the number of white flowers Sally uses be represented by x
This is calculated as:
2/3 = 12/x
Cross Multiply
2 × x = 3 × 12
x = 3 × 12/2
x = 18 white flowers
Therefore, if Sally used 12 red flowers, the number of white flowers will she use is 18 white flowers.
