The first row represents the input. The second row represents the value that the function f assumes for each input above. The third row represents the value that the function g assumes for each input above.
To compute f(1), we look for 1 in the first row (third column) and we look for the correspondent value for f. In this case, we have f(1)=4
Similarly, we look for 3 in the first row (last column) and we look for the value of g. In this case, we have g(3)=3.
Now we can plug the values in the formula:
Answer: f(5) = 16
Step-by-step explanation:
f(n) = (2n + 3)2 – 2n
f(5) = ((2 x 5) + 3)2 – 2 x 5
f(5) = (10 + 3)2 – 10
f(5) = (13)2 – 10
f(5) = 26 – 10
f(5) = 16
Answer:
500cm or 5 meters
Step-by-step explanation:
The ratio of drawing and field is 1:90.
So we have to make 450 m into cm.
450 -> is 45,000
Now we can make 2 fractions,
Cross multiply
90*x = 90x
1*45000 = 45000
90x = 45000
Divide 90 to both sides
x = 500cm
<em>Thus,</em>
<em>the drawing's field is 500cm or 5m long.</em>

A yard is equal to 3 feet. So knowing this we multiply 5280 which is how many feet are in a mile by 2.5 that is the miles we will take into consideration.
5280 x 2.5= 13,200
Now this value we divide it by 3 which is how long a yard is in terms of ft measurement.
