The formula for quadratic equation is given by:

 x² - (sum)x + (product) = 0

so if we have real roots of 3 and 5 

<span> x² - (3 + 5)x + (3*5) = 0
</span> x² - 8<span>x + 15 = 0
</span>
so if we have real roots of -3 and -6  

<span> x² - (-3 - 6)x + (-2*-6) = 0
</span> x² - (-9<span>x) + 12 = 0
</span> x² + 9<span>x + 12 = 0</span>

Find the area of the circle. Round your answer to the nearest hundredth with 3in i really need help
REY [17]

Answer:

The area of the circle with a 3-inch diameter is 7.07 square inches.

Step-by-step explanation:

The formula for the area of a circle is

A = πr²

If you are given diameter, take half of that to get the radius:  3 ÷ 2 = 1.5

Then take the radius, 1.5 and square it  (multiply by itself)  1.5 × 1.5 = 2.25

Then multiply r² times pi. You can use 3.14. (sometimes you will need 3.14159)

2.25 × 3.14 = 7.065

Your instructions are to "round to the nearest hundredth" so you look to the thousandth place and see a 5. Rules fro rounding: "If the number is 5 or higher, add 1 to the place you are rounding to. If 4 or less, leave the place as it is."

You see a 6 in the hundredths place. Add 1. so the rounded answer is 7.07.

Then you put in the units measure. Inches are given, so the Area will be square inches

7.07 in²

Circle K has a diameter of 24 inches. Find the exact length of semicircle HJI. In your final answer, include all of your calcula
Svet_ta [14]
A semicircle's perimeter is half the perimeter of the complete circle.

The perimeter of the complete circle is its circumference which is found by the equation: πD.

Then the equation of the perimeter of the semicircle is πD/2

In this case D = 24 in, then the perimeteir is π (24in/2) = 12π in ≈ 37.7 in

Answer: The exact length is 12π inches and the approximate length is 37.7 inches

The sum of two numbers is 5. The difference of two numbers is -1. Find the numbers
Drupady [299]

Answer:

The numbers are 2 and 3.

Step-by-step explanation:

The smaller number would have been 1 less than the bigger number so that if for example the smaller number is 1 and the bigger number is 2, their difference would have been 1-2 = -1

5 is an odd number so if it were to be divided into two integers, one would be more than the other, namely 2 and 3.

If you double-check their difference:

2-3 = -1

Thus, the two numbers are 2 and 3.
