In a certain colony of bacteria each divides into two every hour. How many will be produced from a single bacillus if the rate of division continues for 4 hours

Answer: Option B, C = 3.

Step-by-step explanation:

Here we have the function:

f(x) = A*cos(x - C)

A is the amplitude, and we can easily see that the amplitude is 2.

Then:

f(x) = 2*cos(x - C)

We also can see that when x = 0, f(x) ≈ -2

This means that:

cos(0 - C) ≈ -1

Cos(C) ≈ -1

Now we can just evaluate in the different options and see which one is the correct option.

Cos(1) = 0.54

Cos(2) = -0.42

Cos(3) = -0.99

Cos(4) = -0.65

The closer option to -1 is when C = 3, then the correct option is option B.

B

Answer: See explanation

Step-by-step explanation:

From the question, we are informed that six friends share a 15 ounce bag of candy. The number of ounce gotten by each friend will be:

= 15/6

= 2 1/2 ounces

We can then deduce that 2 1/2 is between 2 ounces and 3 ounces

Answer:

54

Step-by-step explanation:

deltamath gave me the answer

The length of w is 54 cm.

One of the six mathematical functions used to express the side ratios of right triangles, the trigonometric function includes the sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc). The figure shows these six trigonometric functions in respect to a right triangle. Surveying, engineering, and navigation issues where one of a right triangle's acute angles and the length of a side are known but the lengths of the other sides need to be determined can be solved with ease using trigonometry.

As per the given data:

x = 41 cm

v = 17 cm

∠W = 134°

To find the length of w:

From the cosine law:  [tex]cos(W) = \frac{x^2 + v^2 - w^2}{2xv}[/tex]

[tex]w = \sqrt{x^2 + v^2 - 2xvcos(W)}\\w = \sqrt{(41)^2 + (17)^2 - 2(41)(17)cos(W)}\\w = \sqrt{1681 + 289 + 968.35} = \sqrt{2938.35}\\w = 54 \:cm[/tex]

Hence, the length of w is 54 cm.

Answer:

d. None of the above

Step-by-step explanation:

✔️Area of triangle 1 = ½*b*h

b = 11 in.

h = 3 in.

Area of triangle 1 = ½*11*3 = 16.5 in.²

✔️Area of triangle 2 = ½*b*h

b = 8

h = 9

Area of triangle 2 = ½*8*9 = 36 in²

✔️Area of parallelogram 1 = b*h

b = 11 in.

h = 9 in.

Area of parallelogram 1 = 11*9 = 99 in.²

✔️Area of parallelogram 1 = b*h

b = 9 in.

h = 11 in.

Area of parallelogram 2 = 9*11 = 99 in.²

✅Total area = 16.5 + 36 + 99 + 99 = 250.5 in.²

That's the answer to the equation that was what you were asking for right?

Answer:

14x + 42y

Step-by-step explanation:

7x2=14

7x6=42

14x + 42y

Answer:

x = 11

Step-by-step explanation:

6x + 7 = 73   {Alternate interior angles}

    6x  = 73 - 7

    6x = 66

      x = 66/6

     x = 11

26 letters in the alphabet.

1-20 = 20 numbers.

The probability of getting w = 1/26

The probability of getting 17 = 1/20

The probability of both: 1/26 x 1/20 = 1/520

Answer:

Your change is $2.20

Step-by-step explanation:

4 x $1.50 = $6

2 x $.90 = $1.80

$6 + $1.80 = $7.80

$10 - $7.80 = $2.20

So it's $2.20. Have a nice day :D

Answer:

$2.20

Step-by-step explanation:

4 bags of cotton candy

$1.50 x 4 = $6.00

2 soft drinks

$0.90 x 2 = $1.80

$6.00 + $1.80 = $7.80

$10.00 - $7.80 = $2.20

Answer: 11

Step-by-step explanation:

When you do square root, you're just finding the number that can be multiplied by itself to get what's inside the √ .

So, when you do √121 , you'll get 11. You can check your answer by going backwards: multiply 11 by itself.

Answer:

Step-by-step explanation:

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.

Answer:

y = 8.49

Step-by-step explanation:

cos 45 = 6/y

0.7071 = 6/y

y = 8.49

Answer:

It is a perfect square expression.

It factors to (x+2)^2

===========================================================

Explanation:

The general format for a perfect square is

(a+b)^2 = a^2 + 2ab + b^2

Which can be seen through the use of the FOIL rule.

Compare x^2+4x+4 with a^2+2ab+b^2, and we have these three equivalences:

Since x^2 = a^2, we can apply the square root to both sides to get a = x. Similarly, 4 = b^2 leads to b = 2. We could get b = -2, but that would mean 2ab = 2x*(-2) = -4x instead of 4x. So we'll stick with b = 2 instead.

Because a = x and b = 2, we then can say:

(a+b)^2 = a^2 + 2ab + b^2

(x+2)^2 = x^2 + 2*x*2 + 2^2

(x+2)^2 = x^2 + 4x + 4

Showing that x^2+4x+4 factors to (x+2)^2.
