Sector area= 0.5 r^2 * theta (in radians)
arc length = r*theta
3=r*(0.7854)
r=3.82
sector area= 0.5 * (3.82)^2 * 0.7854 = 5.73 sq ft
Answer:
2x + y < 7
Step-by-step explanation:
First we find the slope of the line that passes through the given points. The formula for slope is:

Using our points, we have

The y-intercept will be the point where the data crosses the y-axis. All y-intercepts have an x-coordinate of 0; since we already have the point (0, 7), we have the y-intercept at 7. This makes our equation
y = -2x + 7
The inequalities we're given are written in standard form, Ax+By=C. This means we need x and y on the same side of the equals in our equation.
Since the inequality is graphed below the line, we want our inequality to be
y < -2x+7
To move the x-value to the other side of the equation, we will add 2x to each side:
y+2x < -2x+7+2x
y+2x < 7
2x+y < 7

Answer:
887 and 792 km per hour
Step-by-step explanation:
Lets call the first plane A and the second B
we know that: a=b+95
We can say that 3358=2b+(2b+190)<=A
When solved, we get 3168=4b
b=792 km per hour.
Go back to step two. A=b+95, so A=792+95=887 km per hour
The two planes rates are 887 km per hour and 792 km per hour.
