Answer:
The answer to your question is a) 588.6 N b) 132.3 N
Step-by-step explanation:
Data
mass = 60 kg
weight = ?
Process
1.- Write the formula of weight
Weight = mass x gravity
gravity = 9.81 m/s²
2.- Substitution
Weight = 60 x 9.81
3.- Result
Weight = 588.6 kg m/s² = 588.6 N
4.- Convert Newtons to Pounds
1 pound ----------- 4.45 N
x ----------- 588.6 N
x = (588.6 x 1) / 4.45
x = 132.3 pounds
Answer:
Statement 1 and 2
Step-by-step explanation:
If you take t^2 - 16t + 55 and find some of its graphical values, you will get:
Turning point: (8,-9)
Roots: (5,0) and (11,0)
When this graph is plotted and you imagine the x axis to be time (as stated in the question), each of the roots (x - intercept) must be when the swimmer goes under and when they come back up.
This means that the swimmer dived under the water at 5 seconds and came back up at 9, making the first 2 statements correct.
Now the fourth statement is ruled out.
The fifth statement is not plausible as the graph would have to have more than 2 roots for the swimmer to enter the water twice.
That leaves the third statement. If you imagine the depth of the swimmer to be the y axis of our imaginary graph, and we know that the y axis of the turning point is -9, that means that the swimmer's deepest dive was 9 feet under the water, ruling out the third statement too.
Hope this helps :D
<span>For a system of equations to have infinitely many solutions, the equations have to be lineary dependent, (i.e. one of the equations is a multiple of the other equation). For the given equation to have infinitely many solutions, the second equation have to be a multiple of the first equation.
The first equation can be rewritten as y - 2x = -5
The second equation is the first equation multiplied by 2, i.e. 2(y - 2x= -5) = 2y - 4x = -10
Therefore, the correct answer is -10 (option a).</span>
Answer:
(4,7)
Step-by-step explanation:
28°
Since KL and FG are perpendicular they create a 90° angle. 180-90-62=28
