Steve cycled 35 miles in 2 1⁄2 hours. What is the average speed that Steve traveled?

1 answer:

4 0

35 miles divided by 5 is 7 miles. 2.5 divided by 5 is 0.5 hours. But you need 1 hour, so 0.5*2=1 and 7*2=14 so the answer is 14 miles per hour.

Line XY was drawn on a plane. Using a compass and a straightedge the student wanted to construct an equilateral triangle. What w

Andrew [12]

1. Place your compass point on X and measure the distance to point Y. Swing an arc of this size above (or below) the segment.

2. Without changing the span on the compass, place the compass point on Y and swing the same arc, intersecting with the first arc.

3. Label the point of intersection as the third vertex of the equilateral triangle.

4. Use you straight edge and connect the points.

Y=-x^2+20x-64 what is the max height

Inessa [10]

Answer:

Step-by-step explanation:

The maximum height is the y-coordinate of the vertex

given a quadratic in standard form : ax² + bx + c : a ≠ 0

then the x-coordinate of the vertex is

$x_{vertex}$ = - $\frac{b}{2a}$

y = - x² + 20x - 64 is in standard form

with a = - 1, b = 20 and c = - 64, hence

$x_{vertex}$ = - $\frac{20}{-2}$ = 10

substitute x = 10 into the equation for y

y = - (10)² + 20(10) - 64 = 36 ← max height
