The answer to 14 is 13 as in the number not the question
and 13 I'm not so sure
Answer:
The roots are
, which is given by option C.
Step-by-step explanation:
Solving a quadratic equation:
Given a second order polynomial expressed by the following equation:
.
This polynomial has roots
such that
, given by the following formulas:



In this question, we have that:

Which is a quadratic equation with
. So



So the roots are
, which is given by option C.
See attached picture and check solution below.
We are given with the following values:
A = length of transmission line = 96ft
B = length of shadow = 72 feet
C = distance of ladder to base of transmission line = 66 feet
Solve for angle created between the wire and tip of the shadow:
tan x = opposite/ adjacent
tan x = 96 feet / 72 feet
x = 53.13°
Solving for the height of the ladder:
tan x = Ladder length / (72-66)
tan 53.13° * (72-66) = ladder length
ladder length = 8 feet
The answer is letter "B" which is 8 feet.
Answer:what’s the question
Step-by-step explanation:
Answer:
D). (n + 4)^3/5.
Step-by-step explanation:
The fifth root is equal to exponent 1/5 and the n + 4 is taken to the power 3 so the answer is (n + 4)^3/5.
