Answer:
B) 6
Step-by-step explanation: g = x - 9, g = 15 - 9. 15 - 9 = 6.
Answer:
Value of y is 1536.
Step-by-step explanation:
We have given an expression 
We need to find the value of y when x=8
We will substitute the value of x as 8 in the given expression we get
On simplification we get
On further simplification we get:
Hence, the required value that is the value of y is 1536
That is true. 4 and 5 are corresponding angles.
Answer: (B) The price elasticity of demand for good Z = 0.86
Step-by-step explanation:
The formula for determining elasticity of demand by using the midpoint method is
(Q2 - Q1)/[(Q2 + Q1)/2] / (P2 - P1)/[(P2 + P1)/2]
Where
P1 is the initial price of the item.
P2 is the final price of the item.
Q1 is the initial quantity demanded for the item.
Q2 is the final quantity demanded for the item.
From the information given,
P1 = 10
P2 = 15
Q1 = 85
Q2 = 60
The price elasticity of demand for good Z = (60 - 85)/[(60 + 85)/2] / (15 - 10)/[(15 + 10)/2]
= (-25/72.5) / (5/12.5) = -25/72.5 × 12.5/5
= - 312.5/362.5 = - 0.86
I think it would be 315. because 4.5*70..but im not sure
