Answer:
No. They are not equivalent.
Step-by-step explanation:
=>
Therefore, 3/5 and 1/2 are not equivalent.
Hoped this helped.
Answer:
dy/dx = -b/a cot α
Step-by-step explanation:
x² / a² + y² / b² = 1
Take derivative with respect to x.
2x / a² + 2y / b² dy/dx = 0
2y / b² dy/dx = -2x / a²
dy/dx = -b²x / (a²y)
Substitute:
dy/dx = -b²a cos α / (a²b sin α)
dy/dx = -b cos α / (a sin α)
dy/dx = -b/a cot α
Answer:
A. 70 miles per hour B. 620 miles from home
Step-by-step explanation:
This function is a linear equation, following the slope-intercept form of a line. This standard form is y = mx + b, where m is the slope and b is the y-intercept. The slope of a line is the rate at which the steepness of the line is changing. The y-intercept is where the function is "starting".
In our case, the number in the rate of change position is 70. It is being multiplied by t. If t = 1, that means that after 1 hour, we have gone 70 miles. If t = 2, that means after 2 hours we have gone 140 miles. If t = 3, that means that after 3 hours, we have gone 210 miles; etc. That number in the slope position represents the rate at which you are traveling PER HOUR; the slope.
The "starting" position of day 2 is found in the y-intercept. Replacing x with 0, meaning NO time has gone by at all, at the beginning of the second day, we are starting 620 miles from home.
Answer:
y=4x+10
Step-by-step explanation:
It's parallel so it has the same slope of 4.
Then, using slope-point formula
y-y_1=m(x-x_1)
y-6=4(x-(-1))
y-6=4x+4
y=4x+10
