Answer:16.56 cm
Step-by-step explanation:
5.8*1.2=6.96
6.4*.8=5.12
1.2+.8=2
5.6-2-3.6
5.6*.8=4.48
4.48+5.12+6.96=16.56
Answer:
+4.245
Step-by-step explanation:
Before you can find the square root of x^2, you have to EVALUATE
64+49-2(8)(7)cos32, and THEN take the square root of the result:
64+49-2(8)(7)cos32 = 64 + 49 - 112(0.848) = 113 - 94.981 = 18.019
Then x^2 = 18.019.
Find the square root of 18.019: It is +4.245. A negative result here would make no sense.
It’s just 5x^3.
Just omit the absolute value symbol :)
