Answer: the golf ball with hit the ground again after 2.75 seconds
Step-by-step explanation:
The movement of the golf ball from the ground follows the equation h(t)=-16t^2+44t,
where t is the time in seconds, and h(t) is the height of the ball at a given time t
By the time the golf ball hit the ground, the height from the ground would be zero. This means that we would equate the quadratic equation to zero. It becomes
-16t^2+44t = 0
Dividing both sides by t
16t^2/t = 44t/t
16t = 44
t = 44/16
t = 2.75
35 : 10 = 7*5 : 2*5 = 7 : 2
Thus 35 : 10 = 7 : 2;
but 35:10 ≠ 7:5
Answer:
The distance between F and A is approximately 6.71 units.
Step-by-step explanation:
To find the distance between any two points, we can consider using the distance formula. Recall that:
Let F(-2, 1) be (<em>x</em>₁, <em>y</em>₁) and A(4, -2) be (<em>x</em>₂, <em>y</em>₂).
Substitute and evaluate:
In conclusion, the distance between <em>F</em> and <em>A</em> is approximately 6.71 units.
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
