To find a perfect square we want the equation to look like (y - 8)(y-8) because
the two numbers that add up to -16 and multiply into 64. are -8, -8. -8^2 is 64.

How do you find the percent change?

antoniya [11.8K]

Hello!!
To calculate the percentage increase<span>: First: work out the </span>difference<span> (</span>increase<span>) between the two numbers you are comparing. Then: divide the </span>increase<span> by the original number and multiply the answer by 100. If your answer is a negative number then this is a </span>percentage<span> decrease.
</span>let me know if u have anymore questions!:)

Suppose two adjacent endpoint of a rotated square are located at (-4, -6) and (5, -1) on the coordinates axes. What is the lengt

Rufina [12.5K]

To find the length of the side of the square, we just need to find the distance between the two endpoints. This problem can quickly be solved by using the distance formula, but for those who are not familiar with it, we can simply solve it by analyzing a triangle.

Take a look at the diagram below. We are interested in x. To find this we have created a right triangle. The horizontal component is just the distance between the x coordinates of the two points while the vertical component is the distance between the y coordinates.

The horizontal component is 9 and the vertical component is 5. We can now get x by using the pythagorean theorem:

$x^{2}= 9^{2} + 5^{2} =81+25=106$
$x= \sqrt{106}$ which is approximately equal to 10.30 units.

ANSWER: The length of the side of the square measures 10.30 units.

Under certain conditions, the number of bacteria present in a colony is approximated by f(t) = Age 0.023t, where t is in minutes

AleksandrR [38]

Answer:

5 min: 3,029,058
10 min: 3,398,220
60 min: 10,732,234

Step-by-step explanation:

The given function is evaluated by substituting the given values of t. This requires using the exponential function of your calculator with a base of 'e'. Many calculators have that value built in, or have an e^x function (often associated with the Ln function).

<h3>5 minutes</h3>

The number of bacteria present after 5 minutes is about ...

f(5) = 2.7×10^6×e^(0.023×5) ≈ 3,029,058

<h3>10 minutes</h3>

The number of bacteria present after 10 minutes is about ...

f(10) = 2.7×10^6×e^(0.023×10) ≈ 3,398,220

<h3>60 minutes</h3>

The number of bacteria present after 60 minutes is about ...

f(60) = 2.7×10^6×e^(0.023×60) ≈ 10,732,234
