Answer: Choice D
y = cos(x+pi)
============================================
Explanation:
Make sure your calculator is in radian mode.
If we plug x = 0 into each answer choice, we get the following
Choice A: y = cos(x+pi/2) = cos(0+pi/2) = 0
Choice B: y = cos(x+2pi) = cos(0+2pi) = 1
Choice C: y = cos(x+pi/3) = cos(0+pi/3) = 1/2 = 0.5
Choice D: y = cos(x+pi) = cos(0+pi) = -1
Only choice D has x = 0 lead to y = -1.
Therefore (0,-1) is a point on the equation of choice D. The graph shows this visually through the y intercept, where the graph crosses the y axis.
Answer:
70
Step-by-step explanation:
1+9+40-40+40+10*2
----------------------- 20
10+40-40+40+20
50 (-40+40 cancels out to 0) +20
50+20= 70
(Following PEMDAS)
Multiply, add, subtract.
if you were to instead go through it left to right, you would get 120, which is incorrect.
Hello,
Let's put the 6 houses on side: 6P9=9*8*7*6*5*4/6! = 84
For each choice there are 3! choices pour the other side
84*3!=504
Answer:
question 1 , area= 42.02 sq meter, circumference=22.98 meter
question 2, area=481.609sq meter, lenght of BC=263.3472 meter
for convience i converted yards to meter.
Step-by-step explanation:
in first question to find area of circle by multiplying value of pi (3.14) and square of radius of circle and to find circumference just multiply 2 with value of pi(3.14) and radius of circle.
in the second question to find area of sector use formula 1/2 r^2 x72 and to find lenght of arc bc use formula length= radius x 72
Answer:
huh??
