Given :
Length of yarn, l = 225 yards.
Number of bracelets he made, n = 1000 .
To Find :
How long will the yarn be for each bracelet.
Solution :
Let, length of yarn used in each bracelet is x.
So,
Therefore, length of yarn used in each bracelet is 0.225 yard.
Answer:
B
Step-by-step explanation:
the correct answer is B.
sqrt of X
Answer:
Part 16) The marginal revenue is $4,000
Part 17) The marginal average cost function is (70x+41)
Step-by-step explanation:
Part 16) we know that
The marginal revenue function is simply the derivative of the revenue function
we have
Find 
For x=1,000 units
substitute
Remember that the units is in thousands of dollars
therefore
The marginal revenue is $4,000
Part 17) we know that
The marginal average cost function is simply the derivative of the average cost function
we have
Applying the distributive property
Find the derivative
therefore
The marginal average cost function is (70x+41)
Answer:
The Arithmetic progression formed will be: 7, 12, 17, 22...
a = 7, d = 5
The nth term or an = a + (n-1)d
= 7 + (n-1)5
= 7 + 5n - 5
= 5n + 2
The answer is A. 5n + 2
Hope this helps!
In this case or scenario,
the double-angle identity that should be used is the one for cosine. <span>
In totality, we shall need the following three trigonometric
identities to end up with the equality:
<span>1. cos (2a) = cos² (a) - sin² (a)
2. sin² (a) + cos² (a) = 1
<span>3. tan² (a) + 1 = sec²
(a)
<span>Using identities 1 and 2 on the left-hand side of the
equation, we get the following:</span>
1 + cos (2a) = 1 + cos² (a) - sin² (a) = 2 cos² (a) </span></span></span>
<span>
<span>Recalling that cos² (a) = 1 / sec² (a) and applying identity
3, we find the following:</span>
2 cos² (a) = 2 / sec² (a) = 2 / (1 + tan² (a)) </span>
Therefore giving us:
<span>2 cos² (a) = 2 / (1 +
tan² (a))</span>
