This sequence is:
a(n)=-11(-4)^(n-1)
The sum of the sequence is:
s(n)=-11(1--4^n)/(1--4)
s(n)=-11(1--4^n)/5
so for the first seven terms
s(7)=-11(1--4^7)/5
s(7)=-11(1+16384)/5
s(7)=-11(16385)/5
s(7)=-36047 B.
Answer: 10
Step-by-step explanation:
Use Pythagorean theorem!
a^2+b^2=c^2
6^2+8^2=c^2
64+36=c^2
100=c^2
Take the square root of 100 and you get c=10
3 nickles plus 8 pennies
(3x5)+(8x1) = 15 + 8 = 23
= 23¢
Answer:
33.33 square yards
Step-by-step explanation:
Recall that 1 yd = 3ft.
(20 ft)(15 ft) = 300 ft^2
Converting this to square yards, we multiply the above result by
(1 yd)^2
------------
(3 ft)^2
obtaining
(300 ft^2) (1 yd)^2
-------------- * ------------- = 33.33 square yards
1 9 ft^ 2
Answer:
Linear functions are equations where the greatest power of the variable (typically x) is 1;
They are graphed as straight lines;
So, any function that has the following format:
f(x) = ax + b;
Nonlinear functions would be any equation that has a variable to a power greater than 1;
This could be a quadratic equation or an exponential equation
