write a degree 3 polynomial with zeros 1, 5i, and -5i
Answer:
x^3 -x^2 + 25x - 25
Step-by-step explanation:
x = 1
x = 5i
x = -5i
(x - 1)(x - 5i)(x + 5i)
Multiply
(x - 1)(x^2 + 5ix - 5ix + 25) *Remember that i multiplied by i equals negative and in this situation, one of the variables was already negative, so negative multiplied by negative is positive*
(x - 1)(x^2 + 25)
Multiply again
x^3 + 25x -1x^2 - 25
x^3 -x^2 + 25x - 25
On the first day of a family road trip, Kai's family travels 365 miles.
On the third day, they travel 20% farther.
How many miles does Kai's family travel on the third day?
The number of miles traveled by Kai's family as required in the task content is; 73 miles.
How many miles was travelled on the third day?It follows from the task content that the number of miles traveled by Kai's family on the third day is to be determined.
On this note, since the family travelled 365 miles on the first day and travelled 20% farther on the third day;
The number of miles traveled on the third day can be modelled as;
= 20% of 365
= (20 / 100) × 365
= 73 miles.
On this note, the number of miles traveled on the third day is; 73 miles.

What is the side length of a square that has an area equal to 49 squared
inches? *
s= 7 inches
s= 6 inches
s= 5 inches
s= 8 inches
Please help me
Answer:
s= 7 inches
Step-by-step explanation:
Let the side length be x
Area of square = side × side OR [tex]side^{2}[/tex] (lets put x in place of side)
[tex]49^{2}[/tex] = x
7 = x
Side length = 7 inches
Answer:
7 inches
Step-by-step explanation:
Area of a square = 49 sq. inches
side *side = 49
side = [tex]\sqrt{49}=\sqrt{7*7} = 7 \ inches[/tex]

A garden store purchased a lawn mower and marked it up 160% from the original cost of
$82.67. A week later, the store placed the lawn mower on sale for 10% off. What was the
discount price?
Answer:
$119.04
Step-by-step explanation:
160% of $82.67
= 160/100 * 82.67
= 16/10 * 82.67
= $132.272
After discount,
90/100 * 132.272
= 119.0448
≈ $119.04
