Answer:
Greatest integral value of K = 3.
Step-by-step explanation:
The nature of the roots of a quadratic equation is determined by the sign of the discriminant, b^2 - 4ac. For non-real roots this is negative.
2x^2 - kx + 9 = 0
The discriminant = (-k)^2 - 4*2*2 , so:
k^2 - 16 < 0 for non-real roots.
k^2 < 16
k < √16
k < 4
So the answer is 3.
The greatest integral value is 8.
Answer:
8

Step-by-step explanation:
f(x) + n - move the graph n units up
f(x) - n - move the graph n units down
f(x + n) - move the graph n units to the left
f(x - n) - move the graph n units to the right
====================================================
We have f(x) = 2ˣ.
g(x) = f(x) + 1 - move the graph of f(x) one unit up.

Total cost to cover 2100 square foot of home is $231,000
Step-by-step explanation:
Total area of the home = 2100
Cost per square foot = $110
Cost of complete area of home = Total area of the home x Cost per square foot
Cost of complete area of home = 2100 X 110
Cost of complete area of home = $231,000
So, Total cost to cover 2100 square foot of home is $231,000
