Answer:
I would say <u>17.6 miles</u>
Step-by-step explanation:
30 miles in 2 hours but we wanna know how many miles in 1.7 hours, I simply divided 30 by 1.7 and got 17.6 miles.
X-15 is greater than or equal to 4
Answer:
3lny - ln7
Step-by-step explanation:
We need to look at two properties that can determine our answer, first off is the obvious rule of subtraction between two logs, when subtracted, the numbers on the right of the log must be divided together.
The other one is the y^3, which means that we need to look for a logarithm that has 3 in the front of it because when a number in front of a logarithm exists, it must turn into an exponent of the number of the right of the logarithm.
With this, we can cross out the ones without the 3 in front, which would be D. lny - ln7 + 3
Now, we see that y is the one with the exponent, meaning that the equation with the 3 in front of the logarithm of y is correct, cross out the ones without, which is A. 3ln7 - ln7
Now when subtracting, the first logarithm will be the numerator while the second logarithm will be the denominator. Leaving us with our final answer being C. 3lny - ln7
(y^3 [3lny] / 7 [ln7])
The formula for the area of a circle is r² x π.
-Since we know the diameter of the circle, we can divide by 2 to find the radius of the circle.
10/2 = 5
-From here, we can substitute our values in. Since we're using 3.14 for pi, we'll substitute that as well.
(5)² x (3.14)
-And finally, we can solve to find the area of the circle.
(25) x (3.14)
(78.5)
Therefore, the answer is 78.5 meters.
