Answer:
A: f(x)=10cos(2π/5 x)+10
Step-by-step explanation:
The coefficient of x in the cosine argument of the function will be 2π/period. Since the period is 5, the coefficient is 2π/5. This observation eliminates choices B and C.
The description "not a reflection of the parent function over the x-axis" means the multiplier of the cosine function is not negative, eliminating choice D.
The remaining choice A matches the description.
Answer:
60
Step-by-step explanation:
We can easily solve this by finding out how many 60 seconds are in 10 minutes, and then dividing by 10.
To do that, multiply 60 seconds by 10, since there are 60 seconds in each minute.
60*10=600. There are 600 seconds in ten minutes.
Now, divide by 10.
600/10=60
There are 60 intervals of 10 seconds in 10 minutes.
Hope this helps!
Answer:
The slope is .
Step-by-step explanation:
The equation is conveniently in slope-intercept form.
m - slope
b - y-intercept
-2/3 is in m's spot, so it is the slope of the equation.
Hope this helps.
Surface area will consist of:
2 triangles, 3 rectangles:
Solving for triangles:
A=1/2bh
A=1/2(120)
A=60
60*2 gives us the surface area of both triangular sides.
Solve for rectangles:
(17*20)+(8*20)+(15*20)
(340)+(160)+(300)
(800)
800+120=920
The surface area of the prism is 920 square feet
