Answer:
B
Step-by-step explanation:
We want to find the equation of a line with a slope of 3 that includes the point (0, 5).
We can use the slope-intercept form, given by:
Where m is the slope and b is the y-intercept.
Notice that the given point (0, 5) is already the y-intercept. So, b = 5.
By substitution, we acquire:
Hence, our answer is B.
Answer:
D) 19.8 lbs
Explanation:
1kg in household measurement is equal to 35.274 ounces. 35.274*9=317.466 ounces.
1kg is also equal to 2.205 lbs. 9*2.205=19.8416
9 kg is also equal to 9000 grams, but grams are not a part of the household measurement system
a) 9000 grams. b) 9000 ounces. c) 19.8 ounces. d) 19.8 pounds.
This leaves us with 19.8 lbs
Answer:
A. 30 meters
Step-by-step explanation:
Let's find the answer.
The problem established a quadratic relationship between height (h) and time (t), then we can establish:
h(t)=K*t where 'K' is a coefficient.
Because an experiment was done, we can find 'K' as follows:
h(t)=K*t
90meters=K*(3seconds)
90meters/3seconds=K
30m/s=K
Now we can solve the problem, so for 2 seconds:
h(t)=K*t
h(t)=(30m/s)*(2s)
h(t)=60m
But notice that the obtained 60 meters are the distance traveled in 2 seconds from the top the building to the ground. So 'how far from the ground' can be calculated as:
(far from the ground) = (total building height) - (distance traveled in 2s)
(far from the ground) = 90m - 60m = 30m
In conclusion, after 2 seconds, the ball is 30 meters far from the ground. The answer in then A. 30 meters.
