Answer:
The car is traveling 475200 feet per hour. That means in 2 seconds it will have gone 264 feet.
Step-by-step explanation:
you have to times 90 by 5280 to get the feet per hour. And then divided by 60 twice the first time you get minute and then when you divided by 60 again you get seconds and then you times it by 2 to get 264 feet a second.
Answer:
A = (16π -32) in²
P = (4π +8√2) in
Step-by-step explanation:
The area is that of a quarter-circle of radius 8 inches less half the area of a square with side length 8 inches. Two formulas are useful:
area of a circle = πr² . . . . .r = radius
area of a square = s² . . . . s = side length
Then your area is ...
A = (1/4)π(8 in)² - (1/2)(8 in)² = (64 in²)(π/4 -1/2)
A = (16π -32) in²
____
The applicable formulas for the side lengths of your figure are ...
arc BD = (1/4)(2πr) = π(r/2) = π(8 in)/2 = 4π in
segment BD = (8 in)√2
The perimeter is the sum of these lengths, so is ...
P = (4π +8√2) in
_____
Of course, you are very familiar with the fact that an isosceles right triangle with side lengths 1 has a hypotenuse of length √(1²+1²) = √2. Scaling the triangle by a factor of 8 inches means the segment AB will be 8√2 inches long.
Answer:
Option D.
Step-by-step explanation:
We need to find the solution to the system graphed below.
If a system of equation have 2 linear equation then the intersection point of both lines lines is the solution of the system of equations.
In the given graph two straight lines intersect each other at (-1,-1).
Point of intersection = (-1,-1)
So, by using the given graph we can conclude that the solution of given system of equations is (-1,-1).
Therefore, the correct option is D.
In polar coordinates, the axis determined by theta=0 is called the
positive x-axis or horizontal axis.
To add, in mathematics, the polar coordinate<span> system is
a two-dimensional </span>coordinate<span> <span>system in
which each point on a plane is determined by a distance from a reference point
and an angle from a reference direction.</span></span>
