Answer:

the answers are A B AND D

Step-by-step explanation:

To find perpendicular lines you take the slope and change the sign and find the reciprocal. after doing that you set it up as a new equation that you will use to find b using the point.

in this case

y= - 2/5x +b

plug in the x and y values of the point (5, -4) to find b

b= -2

you put that together to get the equation

Wich number is the principal square root of 49
myrzilka [38]
A principle square root of a real number that's not negative, such as 49, is the square root of that number that is not negative.

If you take the square root of 49, you get either -7 or 7, since both 7^{2} and (-7)^{2} equal 49. However, the principle square root would be A) 7, since it's not negative.

A bacterial culture grows exponentially according to the function n(t)=n(e^n), where n(t) is the quantity after t hours and n is
mart [117]

Answer:

n(t=2) = 2 e^{1.386294361(2)}=32 grams

So then after 2 hours we will have 32 grams.

Step-by-step explanation:

For this case we have the followin exponential model:

n(t) = n e^{rt}

n(t) is the quantity after t hours, n is the original quantityand t represent the hours and r the rate constant.

For this case we know that n(0) = 2 grams and n(3) = 128 grams and we want to find n(2)=?

From the initial condition we know that n = 2, and we have the model like this:

n(t) = 2 e^{rt}

Now if we apply the other conditionn(3) = 128 we got:

128 = 2 e^{3r}

If we divide both sides by 2 we got:

64= e^{3r}

If we apply natural log for both sides we got:

ln(64) = 3r

r = \frac{ln(64)}{3}=1.386294361

And our model is this one:

n(t) = 2 e^{1.386294361t}

And if we replace t = 2 hours we got:

n(t=2) = 2 e^{1.386294361(2)}=32 grams

So then after 2 hours we will have 32 grams.

A circle with radius 16 centimeters is inscribed in a square.Which is the area of the shaded region? A. 804.25 square feet B. 10
Dmitrij [34]

<u><em>Answer:</em></u>

Area of shaded region = 220.16 ft²

<u><em>Explanation:</em></u>

The diagram associated with this question is shown in the attached image

Unit in diagram is ft, so I'll use this unit in the answer

We are given that a circle with radius 16 ft is inscribed in a square

We know that the radius of an inscribed circle in a square is equivalent to half the length of the side of the square

<u>This means that:</u>

side length of the square = 2 × radius = 2 × 16 = 32 ft

<u>From the diagram, we can note that:</u>

area of shaded region = area of square - area of circle .............> equation I

<u>1- getting area of square:</u>

Area of a square is the square of its side length

<u>This means that:</u>

Area of square = (32)² = 1024 ft²

<u>2- getting the area of the circle:</u>

Area of circle = πr² = 3.14 × (16)² = 803.84 ft²

<u>3- getting area of shaded region:</u>

<u>Use equation I</u>

area of shaded region = area of square - area of circle

area of shaded region = 1024 - 803.84 = 220.16 ft²

Hope this helps :)
