The answer is c no solution
Answer:
vertical angle theorem
Step-by-step explanation:
angles that are opposite of each other and formed by two intersecting straight lines, are congruent.
Answer:
3 * 10^3 in scientific notation.
3,000 in standard notation.
Step-by-step explanation:
We divide:
3.9 *10^5 / 1.3 * 10^2
= ( 3.9/1.3) * (10^5 / 10^2)
= 3 * 10(5-2)
= 3 * 10^3.
This equals 3 * 1,000 = 3000.
Answer:
y = 5cos(πx/4) +11
Step-by-step explanation:
The radius is 5 ft, so that will be the multiplier of the trig function.
The car starts at the top of the wheel, so the appropriate trig function is cosine, which is 1 (its maximum value) when its argument is zero.
The period is 8 seconds, so the argument of the cosine function will be 2π(x/8) = πx/4. This changes by 2π when x changes by 8.
The centerline of the wheel is the sum of the minimum and the radius, so is 6+5 = 11 ft. This is the offset of the scaled cosine function.
Putting that all together, you get
... y = 5cos(π/4x) + 11
_____
The answer selections don't seem to consistently identify the argument of the trig function properly. We assume that π/4(x) means (πx/4), where this product is the argument of the trig function.
