Answer:
The fastest runner is Brooke
Step-by-step explanation:
In order to determine this, we must first put them all in the same terms. For the purpose of this, we will put them all in feet per second.
Tony
12 feet/1 second = 12 ft per second
Brooke
381 feet/27 seconds = 14.11 ft per second
Emily
1 mile/499 seconds = 5280 feet/499 seconds = 10.58 ft per second
Frank
710 feet/1 minute = 710 feet/60 seconds = 11.83 ft per second
So we know that the fastest is Brooke
Answer: OPTION A
Step-by-step explanation:
Apply the formula for calculate the distance between two points to know the value of the diameter of the circle:
The equation of the circle is standard form is:
Where r is the radius and (h,k) is the point of the center of the circle.
As we know the diameter, we can find the radius:
Substitute it into the equation:
Then, the answer is:
Answer:
an = -6*(1/4)^(n-1)
Step-by-step explanation:
We have that the recursive formula for the given geometric sequence is:
a1 = -6
an = (an-1) * (1/4)
With the above we can assume that:
r = 1/4
following the rule of the explicit formula that is given by:
an = a1 * (r) ^ (n-1)
we substitute and we have:
an = -6 * (1/4) ^ (n-1)
Therefore the explicit formula from the given data would be:
an = -6 * (1/4) ^ (n-1)
Y = (4/9) x for number 9
<span>y = (900/10) x or y = 90x for number 10</span>
<span>These equations are in y = mx + b which is good when graphing.</span>
<span>where m = slope = change in y divided by the change in x. </span>
<span>Time would always be on the x axis. </span>
Answer:
About 2105.98
Step-by-step explanation:
31% of 3354 is 1039.74
3354-1039.74=2314.26
9% of 2314.26 is 208.2834
2314.26-2018.2834=2105.9766
