Answer:
2i
Step-by-step explanation:
Distribute:
(5y + 2)(y - 3)
5y^2-15y+2y-6
Which can be simplified into 5y^2-13y-6
Now the equation now looks like this: 5y^2-13y-6=-13(2+y)
For -13(2+y) multiply -13 with 2+y
Which is -26-13y
5y^2-13y-6=-26-13y
Simplify:
5y^2+20
Which can be simplified into 5(y^2+4)
y^2+4=0
y^2=-4
y=2i

When an object moves in a circle the __________ of the object is continually changing. What is the missing word in this sentence?
Answer:
velocity
Step-by-step explanation:
The velocity of the object is continually changing. This velocity is the slope of the tangent line to the curve at a given point on the curve.
The corrected sentence is: When an object moves in a circle, the velocity of the object is continually changing.
What is a circular motionCircular motion involves not only changes in the object's orientation or direction but also changes in its velocity.
Velocity includes both the speed of the object's movement and its direction. As an object moves around a circle, even if it maintains a constant speed, its velocity is changing because the direction in which it is moving is always changing.
This change in velocity is what allows the object to maintain its circular path rather than moving in a straight line.

2 The salary of 157 employees in an office for a month is 710, 582, what is the annual salary of 1 employee, assuming all are paid equally
Answer: $4526
Step-by-step explanation:
Ratio of employees to cash
157:710528
Divide both sides by 157 to find how much 1 employees is paid
1: 4526
Answer:
710 582 - salary of all employees in a month
157 - number of employees
The monthly salary of each employee is 4526.
The 4526 is obtained by dividing the salary of all employees to their number which is 157.
The question is, "What is the salary of 1 employee assuming all are paid EQUALLY?"
To get it, just multiply 4526 into 12 (annually). So the answer is 54312

What is Pythagoras' Theorem?If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:
|AC|^2 = |AB|^2 + |BC|^2
where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).
You start driving east for 5 miles, turn left, and drive north for another 12 miles. At the end of driving,

A square tile has a side length of 12 cm. What is the area of the tile?
48 square centimeters
72 square centimeters
24 square centimeters
144 square centimeters
Answer:
144 cm²
Step-by-step explanation:
Remember: If you are finding the area of a square and are given a side, you can simply square it and it will be the area. Thus:
12 x 12 cm = Area of tile.
=> 144 cm² = Area of tile.
Therefore, 144 cm² is the area.

Jill lives 3 1/2 miles from school. One morning, her friend was giving her a ride. When they were 2/3 of the way to school, their car broke down and they had to walk the rest of the way. Draw a picture to help you figure out how far they walked.
We want to find the distance that Jill and her friend must walk, we will see that the distance is (1 + 1/6) miles
So the total distance of the travel is:
(3 + 1/2) miles.
2/3 of that distance are made in the car, then the other 1/3 is the distance that they must walk. A rough sketch of the situation is shown at the end.
Then we must solve:
(1/3)*(3 + 1/2) miles = ((1/3)*3 + (1/3)*(1/2)) miles
= (1 + 1/6) miles
So the distance that they must walk is (1 + 1/6) miles

Insert each y value into the equation. If it equals -14, then it is a solution to the equation. The only one of these y values that is a solution is the last one, -2.
8 * (-2) = -16
-16 + 2 = -14
So y = -2 is a solution.
