[tex]\rm \: \cos \bigg( \dfrac{3\pi}{2} + x \bigg) = sinx[/tex]

[tex]\rm \: {cos \: (2\pi + x) }[/tex]

[tex]\rm \: \cot \bigg( \dfrac{3\pi}{2} - x \bigg) \: = \: tanx[/tex]

Step-by-step explanation:

Answer:

t=6

Step-by-step explanation:

ground height = 0

(are you sure your formula is correct? isn't it - 16t²?)

if h=16t² +64t+192 is true then

16t² +64t+192 = 0

t² + 4t + 12 = 0

t = (-4 ± √(4² - 4*12)) / 2*1 = (-4 ± √-32) / 2 = -2 ± 2√-2

There is no solution of t

if it is h= - 16t² +64t+192

0 =- 16t² + 64t + 192

t² - 4t - 12 = 0

(t + 2) (t -6) = 0

t should be positive

t = 6 sec

Step-by-step explanation:

Problem:

"After breakfast, Samuel had 3/4 of a gallon of juice left in a container. One serving of juice is 1/16 of a gallon. How many servings of juice remained in the container?"

One serving is 1/16 of a gallon.

The amount left is 3/4 gallon.

How many times the amount of 1/16 gallon is in 3/4 gallon?

3/4 ÷ 1/16 = 3/4 × 16/1 = 48/4 = 12

Answer: 12

Step-by-step explanation:

first you find the volume of a bin.

that is multiplication of 3 dimensions given.

4*4*4=64 cubic feet...

now volume of books..

0.75*0.75.0.25=0.14 cubic feet

now the number of books that will fit the bin=volume of bin/volume of books

64/0.14=455

455 books

We want to see how many books can fit in a bin, given that we know the dimensions of the books and the bin. We will see that 457 books can enter in the bin.

Remember that the volume of a rectangular prism of length L, width W, and height H is just given by:

V = L*W*H

Here we know that each book is:

0.75ft by 0.75ft by 0.25ft

Then the volume of a single book is:

V = 0.75ft*0.75ft*0.25ft = 0.14 ft^3)

While the bin is 4ft by 4ft by 4ft, thus its volume is:

V ' = 4ft*4ft*4ft = 64ft^3

The number of books that fit in the bin is given by the quotient between the bin's volume and the book's volume:

N = (64ft^3)/(0.14 ft^3) = 457 books.

4120_7 = 4•7³ + 1•7² + 2•7¹ + 0•7⁰

4120_7 = 4•343 + 1•49 + 2•7 + 0•1

4120_7 = 1372 + 49 + 14

4120_7 = 1435

In base 12, we use the digits 0-9 as well as A for 10 and B for 11. So

A3B_12 = 10•12² + 3•12¹ + 11•12⁰

A3B_12 = 10•144 + 3•12 + 11•1

A3B_12 = 1440 + 36 + 11

A3B_12 = 1487

In base 36, we assign values between 10 and 35 to the letters A-Z, so that

WXYZ_36 = 32•36³ + 33•36² + 34•36¹ + 35•36⁰

WXYZ_36 = 32•46656 + 33•1296 + 34•36 + 35•1

WXYZ_36 = 1492992 + 42768 + 1224 + 35

WXYZ_36 = 1537019

Answer:

A. 2^11

Step-by-step explanation:

(They are basically asking what's 2^4 × 2^7, but with more words.)

I usually do each exponent individually:

2^4 is the same as 2 × 2 × 2 × 2 = 16 (or you could have read the text to figure that out)

2^7 is the same as 2 × 2 × 2 × 2 × 2 × 2 × 2 = 128

Then just multiply 128 and 16 to get 2,048, and see which option also gives you 2,048.

BUT, you can also:

(Combine the exponents together to get your answer. Just remember that if it's multiplication you add them, and if it's division you subtract them.)

2^4 × 2^7

4 + 7 = 11

2^11 (This equals 2,048 btw. You don't even have to check all the options to get the answer).

Hope this helps friend :)

The last part I learned from another user, while answering one of your other questions. I personally find this mind blowing, lol.

Using proportions, it is found that the correct option is:

c. 100 milliliters of the first brine solution, 900 milliliters of the second brine solution

The 1-liter solution, with 23.5% salt,  is composed by:

Hence, the combined equation is:

[tex]0.1x + 0.25(1 - x) = 0.235[/tex]

[tex]0.1x + 0.25 - 0.25x = 0.235[/tex]

[tex]0.15x = 0.015[/tex]

[tex]x = \frac{0.015}{0.15}[/tex]

[tex]x = 0.1[/tex]

Hence, 0.1L = 100 mL of the first solution, 900 mL of the second, and option c is correct.

Answer:

That's not a question silly.

Step-by-step explanation:

Using the z-distribution and the information given, it is found that the 89% confidence interval for the difference in the proportions that get sick with Selttiks vs the placebo is (-0.07, -0.002).

The proportions, and it's respective standard errors, are given by:

[tex]p_s = 0.13, s_s = \sqrt{\frac{0.13(0.87)}{560}} = 0.0142[/tex]

[tex]p_p = 0.166, s_p = \sqrt{\frac{0.166(0.834)}{560}} = 0.0157[/tex]

The distribution of the difference has mean and standard error given by:

[tex]\pi = p_s - p_p = 0.13 - 0.166 = -0.036[/tex]

[tex]s = \sqrt{s_s^2 + s_p^2} = \sqrt{0.0142^2 + 0.0157^2} = 0.021[/tex]

The interval is:

[tex]\pi \pm zs[/tex]

The critical value using the z-distribution, for a 89% confidence interval, is z = 1.598, hence:

[tex]\pi - zs = -0.036 - 1.598(0.021) = -0.07[/tex]

[tex]\pi + zs = -0.036 + 1.598(0.021) = -0.002[/tex]

The 89% confidence interval for the difference in the proportions that get sick with Selttiks vs the placebo is (-0.07, -0.002).
