The geometric sequence is given by:
an=ar^(n-1)
where:
a=first term
r=common ratio
n is the nth term
given that a=4, and second term is -12, then
r=-12/4=-3
hence the formula for this case will be:
an=4(-3)^(n-1)
where n≥1
Answer:
f(-5) = 15
Step-by-step explanation:
f(x)=5x+40
plug in x as -5
f(-5) = 5(-5) + 40
multiply 5 by -5
-25+40
add -25 to 40
15
Answer:
Hence the correct answer is option (A) 4.708.
Step-by-step explanation:
Solution:-
Now, we need to find the angle of the sector by using sector formula,
We now convert the angle to radian
Now we calculate the length of arc by arc formula
So, The length of steel that must be replaced is 4.708 ft.
Answer:
F(x) = 5x + 7
F(5) = 5*5 + 7 = 25 + 7 = 32
