Answer:
3^15/5^16
Step-by-step explanation:
(3^3 x 3^6 x 5^-4) / (3^-6 x 5^12)
= (3^3 x 3^6 x 3^6) / (5^12 x 5^4)
= 3^15 / 5^16
Answer:
10 km/h
228 km/h
Step-by-step explanation:
We are told the speed of one of the buses. Since we know that both buses only travelled 7 hours, we can multiply the speed of the first bus by 7 hours to get its total distance
10 km/h * 7 hours = 70 km
Now we subtract this amount from the total distance that the two buses are seperated initially
1666 / 70 = 1596 km
Finally, we can divide this remaining distance by the 7 hours that the second bus travelled to get the second buses rate of speed.
1596 / 7 = 228 km/h
**The total distance between both buses is probably wrong and may be 166km and not 1666 as the question states**
This is a parabolic function
A negative lead coefficient means that f(x) is increasing from the left and decreasing to the right. It will have a maximum value vertex.
Answer:
y=3, x=65
Step-by-step explanation:
Since there are little half circles on the angles, that means that they are the same value.
A triangle always adds up to 180 degrees.
You know that x + x + 50 = 180
That means that the 2 angles have to equal 130 degrees because 50+130=180.
If you divide 130 by 2 angles, you get 65 degrees per angle.
Finally, if you know that the two angles are equal, that means that the triangle is an isosceles triangle and the two side lengths are equal.
4y-2=10
4y-2+2=10+2
4y=12, y=3
