Roots: -9,-8
vertex: (-17/12, -1/4)
Answer:
Vertical angles are congruent.
Explanation:
Took geo, did very well.
We know that the lace is also what we would call the circumference of the circle.
And we also know that the circumference of a circle is represented by the equation:
.
We then can use the length of the lace (12.56 ft) to solve for the diameter (d) of the rug. Let us solve for that now:
We now know that the diameter of the rug is
4 ft.
The answer is A) x = 9
We know this because every four sided figure has angles that measure up to 360. So we can subtract all of the angles and then use the remaining angle to solve the problem.
360 - 90 - 90 - 99 = 81.
So with the remaining angle being 81, we can solve for x.
x^2 = 81
x = +/-9
Since +9 is the only answer that makes sense in this case, x = 9.
If giraffes can run 46.93 seconds, it is equivalent to 46.93(1). So, multiply 46.93 by 1.8
You get 46.93(1.8) = <span>84.474 feet per second.</span>
