Hello from MrBillDoesMath!
Answer:
Rule: Y = 5x - 3
Table Line 4: Y (output) = 37
Table Line 5: X (input) = 10
Discussion:
This one had MrBill going for a while! The rule appears to be
Y = 5 * x - 3
Check it out! Substitute some table values (input) and check the (output) values.
Table line 4: Y(8) = 5 * 8 - 3 = 40 - 3 = 37 (Output)
Table line 5: If Y = 47 = 5*x -3 => add 3 to both sides
47 + 3= 5x => as 47 +3 = 50
50 = 5x => divide both sides by 5
x = 50/5 = 10 (input)
Thank you,
MrB
Answer:
here
A= 50
B = 62
Step-by-step explanation:
we know that
area of the regular Pentagon is 5/2*A*B
=5/2*50*62
=7750
Answer:
A. -41/15.
Step-by-step explanation:
15x^2 + 23x - 41 = 0
Product of the roots of ax^2 + bx + c = c/a.
Thus the product of the roots of this equation = -41/15.

Answer:
AC is about 41. 095 miles long.
Step-by-step explanation:
You can use the Law of Cosines to solve this: c^2 = a^2 + b^2 – 2ab cos(C)
Substitute in your values, and you're good to go!
c^2=16^2+28^2-2(16)(28)(cos(117))
c^2 = 256 + 784 - 896(cos(117))
c = sqrt(1040 - 896(cos(117)))
c is about 41. 095 miles long.
