Step-by-step explanation:
use the formula:
v = 30 [final velocity]
u = 10 [initial velocity]
a = 2 [acceleration]
solve for t [time]
By the table, it seems to be that f = 1/2x
Answer:
3xy - xz, or x(3y - z)
Step-by-step explanation:
2x(y-z)+x(y+z) becomes
2xy - 2xz)+ xy + xz)
combining the xy terms, we get 3xy;
combining the xz terms, we get -xz
Thus, the complete simplified expression is 3xy - xz, or x(3y - z)
Answer:
y = 1/3 x + 4
Step-by-step explanation:
The slopes of perpendicular lines are negative reciprocals. The given line is
y = -3x + 7
which is already in the slope-intercept form, y = mx + b, where m is the slope.
The slope of the given line is -3.
The slope of the perpendicular is the negative reciprocal of -3 which is 1/3.
The line we are looking for has an equation of the form
y = 1/3x + b
We need to find b. We use the x- and y-coordinates of the given point as x and y in the equation above, and we solve for b.
y = 1/3x + b
5 = (1/3)(3) + b
5 = 1 + b
4 = b
Now that we know that b = 4, we replace b with 4 in the equation
y = 1/3x + b to get the answer.
Answer: y = 1/3 x + 4
If you would like to know how much time does Elke spend on the weights, you can calculate this using the following steps:
3/4 hour = 3/4 * 60 minutes = 45 minutes on the bikes
1/5 hour = 1/5 * 60 minutes = 12 minutes
12 minutes less than 45 minute: 45 - 12 = 33 minutes on the weights
The correct result would be 33 minutes.
