Answer:
the quotient is keeping batman alive
Answer:
C (-2, 0)
Step-by-step explanation:
y = x+2
intersect the x-axis when y = 0, then
0 = x+2
x = -2
When a line and a curve are tangent to each other, they are joined together by 1 point (x,y). So, you equate both equations either in terms of x or y. For this problem, let's equate in terms of y.
y = k - x
y = x² + 3x + 1
k - x = x² + 3x + 1
k = x² + 3x + x + 1
k = x² + 4x + 1
This would be the value of k. Since we are not given the common point, it can only be expressed in terms of x or y.
The area, to the nearst square inch, of a circle the same size az the bicycle wheel is 531 inches².
<h3>What is the area of the circle?</h3>
A circle is a bounded figure which points from its center to its circumference is equidistant.
Area of a circle = πr²
Where :
π = pi = 22/7
R = radius
The full rotation of the wheel is equal to the circumference of the wheel.
circumference of the wheel = 2 πr
26π = 2 πr
r = 13 inches
Area = 22/7 x 13³ = 531 inches²

Answer:
4a. About 54 times NOT INCLUDING THE FIRST TRIAL
4b. About 60 times NOT INCLUDING THE FIRST TRIAL
Step-by-step explanation:
I say about because we don't know if it's ALWAYS going to be the same results.
4a. Also 12*4 because it's 20 times so 20*4=80 then you add half of it to become 90 and you get 54
4b. 12*5 because 100/5=20 for the 20 trials of them
