Answer:
4 units.
Step-by-step explanation:
As its a tangent to the y axis the radius is 0 - (-4) = 4 units.
Answer:
The correct answer is:
44% (B.)
Step-by-step explanation:
number of times flipped = 50 times
number of times red landed face-up = 22 times
∴ frequency of chip landing with red side face up = (number of times red landed face-up) ÷ (number of times flipped) × 100
= (22 ÷ 50) × 100 = 44%
Algebra 1 Answer Key. ITEM 98. Find the equation that is equivalent to the quadratic equation shown. x2 – 8x – 8 = 0. A. x(x – 4) = 32. B. (x – 8)2 = 64.
Answer:
70 m
Step-by-step explanation:
AB makes a 30-60-90 triangle with the wall.
AC makes a 45-45-90 triangle with the wall.
In a 30-60-90 triangle, the short leg (opposite of the 30° angle) is half the hypotenuse.
In a 45-45-90 triangle, the legs are the same length.
So the distance between the left wall and the laser is 60/2 = 30 m.
The distance between the right wall and the laser is 40 m.
The total distance is therefore 70 m.
