Answer:

Option A. 45 miles

Step-by-step explanation:

A student visiting the Sears Tower Skydeck is 1353 feet or 0.25625 miles above the ground.

We have to find the distance the student can see to the horizon.

We can see in the figure attached r is the radius of the earth.

h is the height of the tower and x is the distance to the horizon.

Now we can calculate the distance x by applying Pythagoras theorem in right angle ΔTOH. (Radius of the earth OH ⊥ tangent distance to the horizon TH)

(h + r)² = r² + x²

By putting the values in the formula

h = height of the tower = 0.25625 miles

r = radius of the earth = 3958.8 miles

(3958.8 + 0.25625)²= x² + (3958.8)²

x² = (3959.05)² - (3958.80)²

x² = 15674126.40 - 15672097.40

x² = 2029

x = √2029

x = 45.04 ≈ miles.

Therefore Option A. 45 miles is the answer.

Find the arc length of the semicircle. Either enter an exact answer in terms of π or use 3.14 for π and enter your answer as a d
PSYCHO15rus [73]

Answer:

Step-by-step explanation:

The formula for the length of an arc is s = rФ.

Thus, the arc length of a semicircle is S = rФ/2.

Here the radius is 5 (half the diameter), and so in this case the arc length is

S = (5 units)π/2, or S = (5/2)(3.14) units, or approximately S = 7.85 units

Algebra 2, I need help!!! Solve x^2 + 6x + 7 = 0. If you are going to comment in here please know the answer, this is so serious
docker41 [41]

Answer:

Third option

Step-by-step explanation:

We can't factor this so we need to use the quadratic formula which states that when ax² + bx + c = 0, x = (-b ± √(b² - 4ac)) / 2a. However, we notice that b (which is 6) is even, so we can use the special quadratic formula which states that when ax² + bx + c = 0 and b is even, x = (-b' ± √(b'² - ac)) / a where b' = b / 2. In this case, a = 1, b' = 3 and c = 7 so:

x = (-3 ± √(3² - 1 * 7)) / 1 = -3 ± √2
