The amount of time his teammate have to catch the ball is equal to 1.774 seconds.
<u>Given the following function:</u>
<h3>How to calculate the amount of time?</h3>
In order to determine the amount of time his teammate have to catch the ball, we would evaluate the given position-time function as follows:
f(t) = -16t² + 25t + 6.
In Mathematics, the standard form of a quadratic equation is given by;
ax² + bx + c =0
Where:
a = -16.
b = 25.
c = 6.
Solving the function by using the quadratic formula, we have:
t = [-b ± √(b² - 4ac)]/2a
t = [-25 ± √[(25² - 4(-16)(6))]/2(-16)
t = [25/32 ± (-1/32)√1009]
t = 25/32 ± (-0.993)
t = 0.781 ± 0.993
t = 0.781 + 0.993
Time, t = 1.774 seconds.
Note: We ignored the negative value because time cannot be negative.

Very easy
just add up all the meadals
japan is 38
so total=104+88+82+x+44+38=356+x
total of all medals is 421 so to find brittan or x you just subtrac the total from the big total so
356+x=421
subtract 356 from both sides
x=65
brittan won 65 medals
let 2nd angle = x
then 1st angle = 2x-15
then you have 90 = x + 2x-15
2x +x = 3x
so now 90 = 3x-15
add 15 to each side
105=3x
x = 105/3 = 35
1st angle = 35 degrees
2nd angle = 2(35) - 15 = 70-15 = 65
Answer:
365
Step-by-step explanation:
February 29 is a date that usually occurs every four years, and is called the leap day. This day is added to the calendar in leap years as a corrective measure, because the Earth does not orbit the sun in precisely 365 days.
Answer:
a8 = 0.004
Step-by-step explanation:
Q is abt a geometric series given by the eqn: an = a1*r^(n-1)
given a1 = 40000, r = 0.1
an = 40000*(0.1)^(n-1)
a8 = 40000*(0.1)^(8-1)
= 40000*(0.1)^7
= 0.004
