You equation will be
2550 + (2550 X 8%)
2550 + (2550 X 0.08)
2550 + 204
= 2754
Answer:
Part 1) In the procedure
Part 2) In the procedure
Step-by-step explanation:
Part 1) Observing the graph
The roots are x=-1/2 and x=4
Remember that, the roots are the x-values when the value of y is equal to zero (the x-intercepts)
That's why Sheldon immediately realizes Howard's solution is incorrect
Part 2) we have

The formula to solve a quadratic equation of the form
is equal to
in this problem we have
equate the equation to zero
so
substitute
Howard's error is in this step, is wrong with the sign of the number 7, is positive instead of negative
Answer:
see below
Step-by-step explanation:
We can write the length as w + 8 and since area is length * width our answer is w * (w + 8) = w² + 8w.
Answer:
A, because the cat is only 15 feet in the air and the TREE is 50 feet
Answer:
k = -10
Explanation:
f(x) = 4x³ - 3kx² + 44x - 30
The divisor is:
Set divisor to zero:
Insert this into equation.
⇒ 4(2)³ - 3k(2)² + 44(2) - 30 = 210
⇒ 32 - 12k + 88 - 30 = 210
⇒ -12k + 90 = 210
⇒ -12k = 210 - 90
⇒ -12k = 120
⇒ k = 120/-12
⇒ k = -10
