The solution is the point where the two graphed lines cross each other.
The solution is (0,5)
Answer:
Step-by-step explanation:
We are given the following in the question:
The length of the pen will be 5 feet more than twice as long as the width of the pen.
Let y be the length and x be the width. Thus, we can write:
Fencing = Perimeter of rectangular pen
The cost of the pen will be $7.50 per foot of fencing.
Total Cost of fencing =
is the required cost function.
Answer:
Step-by-step explanation:
P(4,3), Q(4,1), S(-1,3), R(-1,1)
PQRS is a rectangle
Area= length *breadth
= 2 * √29
= 2√29 sq.units
Answer:
Hence, option B) is true.
Step-by-step explanation:
Given
g(t) = t² - 2
h(t) = t + 4
To determine
Using the formula
In order to determine g(h(-4)), first we need to determine h(-4), so
substituting t = -4 in h(t) = t + 4
h(t) = t + 4
h(-4) = -4 + 4
h(-4) = 0
so we can write
now, to determine g(0), substitute t = 0 in g(t) = t² - 2v
g(t) = t² - 2
g(0) = (0)² - 2
g(0) = 0 - 2
g(0) = -2
so, finally we get
Therefore,
Hence, option B) is true.
