Given : Each Dentalia shell is about 1.5 inches long
⇒ Length of Necklace made with 24 Dentalia shells is (1.5 × 24) = 36 inches
⇒ Length of Necklace made with 18 Dentalia shells is (1.5 × 18) = 27 inches
We can notice that 24 Dentalia shells Necklace is Longer than 18 Dentalia shells Necklace
The Difference of Length of 24 Dentalia shells Necklace and 18 Dentalia shells Necklace gives how much longer the 24 Dentalia shells Necklace is than 18 Dentalia shells Necklace.
⇒ Difference = 36 - 27 = 9 inches
⇒ 24 Dentalia shells Necklace is 9 inches longer than 18 Dentalia shells Necklace
Answer:
The length of side b is 179 ft
Step-by-step explanation:
Given triangle ABC in which
∠A = 33°, ∠B = 63°, c=200
we have to find the length of b
In ΔABC, by angle sum property of triangle
∠A+∠B+∠C=180°
33°+63°+∠C=180°
∠C=180°-33°-63°=84°
By sine law,
The length of side b is 179 ft
Option C is correct.
Answer:
I think the relationship is proportional.
Step-by-step explanation:
Answer:
Increasing in x < 7 and decreasing in x > 7.
Step-by-step explanation:
g(x) = 1 -
<u>If a function is increasing in a interval, its first derivative is positive and if a function is decreasing in an intreval, its first derivative is negative.</u>
Using this concept here,
Substitute x > 7,
the first derivative is negative.Hence it is decreasing in this interval.
Substitute x < 7,
The first derivative is positive.Hence it is increasing in this interval.
Hence the answer is increasing in x < 7 and decreasing in x > 7.
