10 + 12 + 23 ÷ 3 = 15
22 + 23 ÷ 3 =15
45 ÷ 3 = 15
The missing number would be 23 since 22 + 23 is 45 and 45 divided by 3 is 15.
Hope this helped :)
Answer:
c. x > 6
d. λ = 3/100
Step-by-step explanation:
c. You have the idea for the necessary equation:
speed = wavelength·frequency
The inequality is x > 6.
__
d. If λ represents the wavelength in nanometers, the range restriction can be written ...
2/100 < λ < 5/100
A possible value of λ is 3/100.
Hey there!
(-2/5)^2
= (-2/5)(-2/5)
= -2(-2) / 5(5)
= 4/25
Therefore, your answer is l: 4/25
Good luck on your assignment and enjoy your day!
