Answer:
yes (6,7) is a solution.
Step-by-step explanation:
(6,7) is an ordered pair, see it like (x,y). so
x=6
y=7
substitute the variable with the values.
x+y=13
6+7=13
13=13
this is a true statement.
When it is plugged in, the battery line increases
we notice it starts to go up first at t=8
it then goes down, then at t=16, it goes up again
so anywhere where it increases or stays constant
from t=8 to t=12 then t=16 to t=20
8+6=14, or 2pm
12+6=18, or 6pm
16+6=22, 4am
20+6=26, 2 days and 2 hours, 8am
so from 2pm to 6pm and from 4am to 8am
3pm
5pm are the answers
Answer:
A = 660.72 in^2 - A = 98 in^2 = 562.7 in^2
Step-by-step explanation:
Formula for a seven sided polygon/heptagon is:
A = (1/4)na^2 cot(π/n) = nr^2 tan(π/n
n n = 7 sides
side length a = 13.4841 in
inradius r = 14 in
circumradius R = 15.5388 in
area A = 660.72 in^2
perimeter P = 94.3886 in
interior angle x = 128.571 °
exterior angle y = 51.4286 °
To calculate the square from a diameter use this formula: q = √(2a^2) = a√2
side length a = 9.8994949366117 in
diagonal q = 14 in
perimeter P = 39.597979746447 in
area A = 98 in^2
Answer:
In trigonometry, the value of tan 0 is 0. The word 'Trigonometry' is derived from the Greek word and the subject is developed to solve geometric problems involving triangles. It is used to measure the sides of a triangle.
