Step-by-step explanation:
The Y-Intercept of a line is the point where a line's graph intersects (crosses) the Y-axis. ... A y-intercept of -4 means that the graph of a line crosses the Y-axis at the point (0,-4).
Answer:
-0.391 < x < 0.391
Step-by-step explanation:
The Maclaurin series for cosine is:
cos(x) = ∑ (-1)ⁿ x²ⁿ / (2n)!
So the next term would be -x⁶/6!. When the absolute value of this is less than the error:
│-x⁶/6!│< 0.000005
x⁶ / 720 < 0.000005
x⁶ < 0.0036
-0.391 < x < 0.391
Answer:
Eastbound train: 95 miles per hour
Westbound train: 105 miles per hour
Step-by-step explanation:
Let:
- e = speed of the eastbound train
- w = speed of the westbound train
The eastbound train travels 10 miles per hour slower than the westbound train
So e = w - 10
Every hour, the distance between the two trains is the sum of the values.
(w - 10) + w = distance apart in 1 hour
5(w - 10 + w) = distance after 5 hours
Solve:
- 5(w - 10 + w) = 1000
- 5(2w - 10) = 1000
- 10w - 50 = 1000
- 10w = 1050
- w = 105
The westbound train is 105 miles/ hour.
The eastbound train is 95 miles per hour

Answer:
B
Step-by-step explanation:
Distributive property is when you use the number on the outside of the parenthesis to multiply to the inside. So, 36+9=3(12+3), in order to solve it on the parenthesis side you would take 3 and multiply it by 12, giving you 36. Then, you would take 3 and multiply it to the other 3 which gives you 9.
The answer would be 3.3944867e+29 but seeing how you didn’t give more detailing I’m not sure if it’s specifically the answer you need.
