Classify the number -3 into as many categories as it belongs: Natural number, whole number, integer, or rational number.

1 answer:

3 0

-3 is an integer and a rational number.

Natural numbers and while numbers refer to positive numbers, so -3 cannot be either of those.

We know that QRP and ARC are similar.
Therefore:
x : 3.7 = 4.9 : 5.6
5.6 x = 3.7 * 4.9
5.6 x = 18.13
x = 18.13 : 5.6
x = 3.2375

Terry is skiing down a steep hill. Terry's elevation E(t)

in feet after t seconds is given by E(t) = 2000 − 90t.

Write a complete sentence describing Terry's starting elevation and how it is changing over time.

Terry starts at an elevation of 2000 feet and descends at 90 feet per second.

If the graphs of two linear functions are perpendicular, describe the relationship between the slopes and the y-intercepts.

slope: negative reciprocals of one another.

y-intercept: There is no relationship.

Which are the solutions of the quadratic equation x^2=-5x-3

frutty [35]

The correct answer would be $\frac{-5 +/- \sqrt{13} }{2}$

In order to solve for this you must first get the equation equal to 0.

<span>x^2=-5x-3 ----> add 5x to both sides.
x^2 + 5x = -3 ----> add 3 to both sides.
x^2 + 5x + 3 = 0

Now knowing this we can use the coefficients of each one in descending order of power as a, b and c.

a = 1 (because it is the coefficient to x^2)
b = 5</span> (because it is the coefficient to x)
c = 3 (because it is the end number)

Now we can plug these values into the quadratic equation.

$\frac{-b +/- \sqrt{b^{2} - 4ac } }{2a}$

$\frac{-5 +/- \sqrt{5^{2} - 4(3)(1) } }{2(1)}$

$\frac{-5 +/- \sqrt{13} }{2}$

And those would be your two answers.
