Answer: the answer is (A)
Step-by-step explanation:
Answer:
r=3 where r is the common ratio
Step-by-step explanation:
The sum of geometric progression for n terms is given by:
, where is the
first term of the series and r is the common ratio.
Now, according to the question, there are four terms and they form a geometric progression. So sum of four terms is given as and .
Also according to the above formula:
Using the values as given in the question into the above equation we get:
[ Using formula ]
which is the required answer.
Step-by-step explanation:
8÷2(2+2) = <u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u>8</u><u>. </u><u> </u><u> </u><u> </u><u> </u>
2(2 + 2)
= <u> </u><u> </u><u> </u><u> </u><u> </u><u>8</u><u>. </u><u> </u><u> </u><u> </u>
4 + 4
= <u> </u><u> </u><u>8</u><u>. </u>
8
= 1
4^3 is the same as 4 x 4 x 4 = 64
Maximum height occurs when the velocity, derivative of the height function, is equal to zero...
dy/dx=-0.06x+1.53, dy/dx=0 when 0.06x=1.53, x=25.5 yds
The maximum height is then found using this x in the height equation...
h(25.5)=19.5 (to nearest tenth)
I assume they want to know the maximum distance that the football travels before it hits the ground...when h=0 that will represent total distance traveled when we solve for x...
-0.03x^2+1.53x=0
1.53=0.03x
x=51 yds
