Answer:
x≤−4 or x≥7
Step-by-step explanation:
They're just after some straightforward algebra starting from the Law of Cosine. We don't have to evaluate any trig functions or anything like that.
We move the c² and the cosine term to their other sides,
That's it for the algebra.
a,b and c are the side lengths opposite A,B and C respectively. So a=4, b=5, c=2.
We substitute:
Answer: A. 37
Answer:
Step-by-step explanation:
Step one:
given data
we are told you earn $1200
the linear function for the cost is expressed as
y=1200x-----------------1
Step two:
We want to bring out the following information
Independent: The number of screens which is x
Dependent: The total revenue which is y
Function: y=1200x

What is a independent variable?
this is a variable that does not rely on other terns
Answer: 1 bulb
Step-by-step explanation:
Using the proportion of flawed bulbs in the first scenario, you can get the number of flawed bulbs in the other bath.
First scenario total bulbs = 2 + 36 = 38
Proportion of flawed bulbs = 2/38 = 1/19
In a batch of 19, the flawed bulbs are;
= 1/19 * 19
= 1 bulb
