Solution is : <u>2p</u> .
(11k^4 - 4m) + (-2k^4 - 15m)
Add -2k^4 to 11k^4. This would be the same as subtracting 2k^4 from 11k^4
9k^4 - 4m - 15m
Add -15m to -4m. This would be the same as subtracting 15m from -4m
Final Answer: 9k^4 - 19m
Word Form: Nine times the variable k to the forth power minus nineteen times the variable m.
Answer:
The ratios are as follows for the given angle:
sineX=opposite/hypotenuse
cosineX=adjacent/hypotenuse
tangentX=opposite/adjacent
Insert the appropriate values for each:
7.) sinZ=24/40
8.) sinC=14/50
9.) cosZ=24/30
10.) tanC=27/36
11.) cosZ=12/15
12.) cosC=27/45
Answer:
Ca^(2+) or the charge is 2 plus or just 2
Step-by-step explanation:
Charge on the calcium ion = 20*(+1) + 18*(-1) = 20 - 18 = 2
The charge on the calcium ion is +2
