Answer:
8.1
Step-by-step explanation:
ANSWER
C) 5.7 seconds
EXPLANATION
The height of the object is given by:
If the object hit the ground, then the height is zero.
Divide through by -16
Where a=1, b=-4 and c=-10
We substitute into the quadratic formula to obtain,
t=2-√14 or t=2+√14
Time cannot be negative.
Hence, t=5.7 seconds to the nearest tenth.
Answer:
-58
Step-by-step explanation:
We are to find tfhe dot product of u=<-8,9> and v=<5,-2>
u*v = <-8,9>*<5,-2>
u*v = -8(5)+9(-2)
u*v = -40 - 18
u*v = -58
Hence the product of the vectors is -58
2/3=8/12. 10 and 8/12
3/4=9/12. 8 and 9/12
128/12-105/12=23
23/12=1 11/12
No you are incorrect. It is not 2 and 11/12, but 1 and 11/12.
