Answer: 9 pieces of ribbon
Explanation: 4.5 / 0.5 = 9
Answer:
D. 13
Step-by-step explanation:
well since it's a quadratic equation, it can be written in the form of ax²+bx+c=0. So we have a=1, b=b and c= -30. Also the roots are given by the equation-
x= -b±
/2a. So all I did was put the number from the choices which would satisfy the sqrt part and that turned out to be 13 since
=
= 17. So b=13.
Answer:

Let h represent the height of the building.
We have been given that at 3:30 in the afternoon in mid-September the Kimball Tower casts a shadow about 290 feet long when the sun's rays come down at an angle about 35 degrees above the horizontal.
We know that tangent relates opposite side of a right triangle to its adjacent side.

Upon substituting our given values in above formula, we will get:






Therefore, the building is approximately 203 feet high.

Step-by-step explanation:
<u>Recursive sequence
</u>
In a recursive sequence formula, each term
is computed as a function of one or more previous terms. In the formula

n is the number of the term we want to calculate. If n=8, then the formula becomes

We can see
is the previous term. It means we need
to be able to compute
. But we also need
to compute
and so on until some known data is reached. The question provides five terms,
