Answer:
√3/3
Step-by-step explanation:
The circumference of the circle is 144.4 yards
Step-by-step explanation:
The circumference of a circle is C = 2πr, where
- r is the radius of the circle
- π is a constant ratio between the circumference of the circle and its diameter and its value is approximately 3.14
∵ The radius of a circle is 23 yards
- Use the rule above to find its circumference
∵ C = 2πr
∴ C = 2π(23)
∵ π ≅ 3.14
∴ C = 2(3.14)(23)
∴ C = 144.44 yards
- Round it to the nearest tenth
∴ C = 144.4 yards
The circumference of the circle is 144.4 yards

Answer:
I believe the answer is D-100.3 degrees, however, I'm not 100% sure.
Step-by-step explanation:
If x is 1, then 23x is 23, so we have 23-1=22 as the answer.
<span>5.1 </span> Find the Vertex of <span>y = x2-2x-15
</span>Parabolas have a highest or a lowest point called the Vertex . Our parabola opens up and accordingly has a lowest point (AKA absolute minimum) . We know this even before plotting "y" because the coefficient of the first term, 1 , is positive (greater than zero).<span>
</span>Each
parabola has a vertical line of symmetry that passes through its
vertex. Because of this symmetry, the line of symmetry would, for
example, pass through the midpoint of the two x -intercepts (roots or solutions) of the parabola. That is, if the parabola has indeed two real solutions.<span>
</span>Parabolas
can model many real life situations, such as the height above ground,
of an object thrown upward, after some period of time. The vertex of the
parabola can provide us with information, such as the maximum height
that object, thrown upwards, can reach. For this reason we want to be
able to find the coordinates of the vertex.<span>
</span>For any parabola,<span>Ax2+Bx+C,</span>the x -coordinate of the vertex is given by -B/(2A) . In our case the x coordinate is 1.0000 <span>
</span>Plugging into the parabola formula 1.0000 for x we can calculate the y -coordinate :<span>
</span><span> y = 1.0 * 1.00 * 1.00 - 2.0 * 1.00 - 15.0
</span> or <span> y = -16.000</span>
