What are all the roots of x2-4x+29=0

Answers

Answer 1

Answer:

To solve a quadratic equation in the form $ax^2+bx+c=0$ you can use the quadratic formula:

$x_(1,2) = (-b\pm√(b^2-4ac))/(2a)$

In your case, the equation $x^2-4x+29=0$ is identified by the coefficient choice $a=1,\ b=-4,\ c=29$ , so the solving formula becomes

$x_(1,2) = (4\pm√(16-116))/(2) = (4\pm√(-100))/(2)$

As you can see, we have a negative number under a square root, an operation impossible to perform using real numbers. So, this equation has no real solutions.

How to find a fraction between the fractions 14/20 and 15/20

Answers

You can double the fractions, so instead of 14/20 and 15/20 you have 28/40 and 30/40. The fractions still equal the same amount. Between theses two new fractions is the fraction 29/40.
So, 29/40 is between 14/20 and 15/20.

Give one example of when you would draw a diagram to solve an angle measurement problem

Answers

An example of an angle measurement problem is when trying to calculate for the height of a particular object given the distance of the observer from the object and the angle of elevation or depression. For example, you want to find out the height of a building. All you need to know is the distance of your point of origin to the building and the angle of elevation.

Jodi rents a car for 2 weeks. It costs $210 for each week plus $0.10 per mile.Which equation represents the relationship between the number of miles traveled, m, and the total rental cost, r?
O A r = 2(210+ 0.10m)
B. r= 210 + 2 (0.10m)
C. r = 2 (210) (0.10m)
D. r= 2(210) +0.10m

Answers

The equation represents the relationship between the number of miles traveled, m, and the total rentalcost, r is r = 2(210) + 0.10m.

What is the equation?

An equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.

Jodi rents a car for 2 weeks.

It costs $210 for each week plus $0.10 per mile.

Let, the number of miles traveled, m, and the total rental cost, r.

The rent of the car for 2 weeks is;

$= 2 * 210$

The equation represents the relationship between the number of miles traveled, m, and the total rentalcost, r is;

r = the rent of the car for 2 weeks + the total rental cost

r = 2(210) + 0.10m

Hence, the equation represents the relationship between the number of miles traveled, m, and the total rentalcost, r is r = 2(210) + 0.10m.

Fran cut her sandwich into 6 pieces. If Fran ate 1/3 of her sandwich, how many pieces did he eat?

Answers

2 pieces :)

Not sure if you wanted work but here is my explanation:

there are six pieces that she cut out, and she ate 1/3 of the six pieces,

1/3=2/6

since there are 6 pieces 1/3 would then equal 2 pieces. :)

Hope this helps:)

2 because 1/3 is equal to 2/6
