Answer:
So in this sequence, we are adding by 9 in each term
So our pattern is: 7 , 7 +9 , 7 + 2(9) , 7 + 3(9) .....
hence, we can write it as: 7 + 
where n is the number of the term you want
Answer:
41.68201 km=25.9 miles
Step-by-step explanation:
Tina should make 31 inch tall model to replicate 155 feet tall monument.
Step-by-step explanation:
This problem can be solved by direct unitary methods easily-
Firstly, Scale is the ratio of the dimension of the original substance to the dimension of a model
Scale= original dimension/ model dimension
Model is the miniaturised representation of a substance.
The monument is 155 feet tall
Tina replicates it with a scale 1inch: 5 feet
Thus, this means that Tina would need 155*1/5 = 31 inch tall model to replicate the complete length of the monument.
Hence Tina needs to make 31-inch tall model.
Answer:
Answer is 729
Step-by-step explanation:
P(x) = -x - 1
q(x) = 2x^2 - 2
(q o p)(-4) = 2(-x - 1)^2 - 2
(q o p)(-4) = 2(-x^2 + x + x + 1) - 2
(q o p)(-4) = 2(-x^2 + 2x + 1) - 2
(q o p)(-4) = -2x^2 + 4x + 2 - 2
(q o p)(-4) = -2x^2 + 4x
