HELP<br> what is the value of “ c”
Alex

Answer:

7

Step-by-step explanation:

When you match the form

... ax² + bx + c = 0

to the equation

... 3x² + 5x + 7 = 0

it is reasonable to conclude that ...

... a = 3, b = 5, c = 7.

_____

The question presumes you are familiar with the form

... ax² +bx +c = 0

which is often used as the representation of a general quadratic equation. This lets us use a, b, and c instead of specific numbers, to talk about ways of factoring, graphing, or solving equations like this.

If the circumference of the circle above is 31.4 units, what is the area? (Use 3.14 for .) A. 62.8 units B. 78.5 units C. 985.96
jenyasd209 [6]

Answer:

78.5 units

Step-by-step explanation:

To find the area of a circle the formula is πr"2"

First we have to find the diameter the find the radius. We already know that the circumference is 31.4 what we have to do now is work backwards. ( 31.4 / 3.14=10) If the diameter of a circle is 10 the radius is 5. now we just have to follow  πr"2" to find the area of a circle. (5"2"= 25 x 3.14= 78.5 units)

Without using a calculator, match each expression to the correct point.
solniwko [45]

Answer:

The locations of each irrational number are the following:

\sqrt{16} - Point a

\sqrt{27} - Point b

\sqrt{32} - Point c

Step-by-step explanation:

\sqrt{16} is an irrational number that is also rational, since 4^{2} = 16. Then, \sqrt{16} must be point a.

Both \sqrt{27} and \sqrt{32} are greater than \sqrt{25} = 5 and less than \sqrt{36} = 6. Then, both are between 5 and 6. Since \sqrt{27} < \sqrt{32}, \sqrt{27} must be point b and \sqrt{32} must be point c.
