Answer:
Step-by-step explanation:
Shown is one-fourth of a circle. Also, according to the picture, the radius is 28 meters.
The area for a whole circle is 
.
Using that information, we can find the area as if the circle was whole instead of just the fourth.
Now that we know the area of the whole circle, we just have to divide it by four to find the area of the fourth of the circle.
That means that the area of the shape shown is .
I hope this helps!
Moving from a to b, the x component of the desired vector is 7-(-9) = 16, and
the y component is 3-9 = -6.
So the vector from a to b is <16,-6>, and the magnitude is
sqrt(16^2 + (-6)^2 ), applying the Pythagorean Theorem.
Answer:
A
Step-by-step explanation:
y=3/4x+4 best represents the line shown below. Because the slope of this graph is 3/4, and the y-intercept is positive 4. Remember that slope=rise/run. You can find the slope very easily by counting, 3 upwards and 4 rightwards.
Answer:
Approximately 11.99 years
Step-by-step explanation:
This is just a type of problem like finding how long it will take for you to get somewhere. Like in finding how fast you need to go to go to a place that is 60 miles in one hour. All you have to do is divide the distance of the star by the speed of light, and you get the amount of time it will take for the star's light to reach the Earth.
