Answer:

The mass number of the other isotope is 10.01613 amu.

Step-by-step explanation:

Let the percentage abundance of the first isotope be: 10B5 = 19.80%

Then, the percentage abundance of the second isotope will be xB5 = 80.20%

Mass of one isotope = 10.012938 amu

(10*19.80 + x*80.20)/100 = 10.012938 

198 + x*80.20 = 1001.2938 

x*80.20 = 1001.2938 - 198

x*80.20 = 803.2938

x = 803.2938 / 80.20

x = 10.01613

The trigonometric identities equivalent to cos(2·x)/cos(x) are;

cos(x) - (sin(x))/(tan (x))

2·cos(x) - sec(x)

Trigonometric identities are equations of trigonometric functions that are correct for the values of the input and output variables in the equations.

The trigonometric identity for cos(2·x) is specified as follows;

cos(2·x) = cos²x - sin²x

Therefore;

cos(2·x)/(cos(x)) = (cos²x - sin²x)/(cos(x))

(cos²x)/(cos(x)) = cos(x)

sin²(x)/(cos(x) = sin(x) × sin(x)/(cos(x)) = sin(x)·tan(x)

(cos²x - sin²x)/(cos(x)) = (cos²x)/(cos(x)) - sin²(x)/(cos(x)

(cos²x)/(cos(x)) - sin²(x)/(cos(x) = cos(x) - sin(x)·tan(x)

cos(2·x) = 2·cos²x - 1

Therefore; cos(2·x)/cos(x) = (2·cos²x - 1)/cos(x)

(2·cos²x - 1)/cos(x) = 2·cos(x) - 1/cos(x)

2·cos(x) - 1/cos(x) = 2·cos(x) - sec(x)

cos(2·x) = 1 - 2·sin²x

cos(2·x)/cos(x) = (1 - 2·sin²x)/cos(x)

(1 - 2·sin²x)/cos(x) = sec(x) - 2·sin(x)

The expressions equivalent to cos(2·x)/cos(x) are therefore;

cos x - (sin x)·(tan x) and 2·cos x - sec x, which are I and III

The approximate area of the shaded region of the circle is 191 metres squared.

The radius of the circle below is given as 9 metres. The approximate area of the shaded region of the circle can be found as follows:

area of the shaded region = area of the circle - area of the sector uncoloured

Therefore,

area of the circle = πr²

where

Therefore,

area of the circle = π × 9²

area of the circle = 81π m²

Hence,

area of the sector uncoloured = ∅ / 360 × πr²

where

Therefore,

area of the sector uncoloured = 90 / 360 × π × 9²

area of the sector uncoloured = 1 / 4 × π × 81

area of the sector uncoloured = 81 / 4 π

Hence,

area of the shaded region = 81π  - 20.25π

Answer:

m∠14 = 80°

Step-by-step explanation:

Angles m∠13 and m∠14 lies on a straight line. Angles on a straight line sums up to 180°.

Hence we can say that,

m∠13 + m∠14 = 180

100 + m∠14 = 180

m∠14 = 180 - 100

m∠14 = 80

We can use the equation:

amount of a given nutrient / % of recommended daily amount = recommended daily amount

Here, we know that 69 grams of carbohydrates is 22% of the recommended daily amount, so we can plug in the given values and solve for the recommended daily amount:

69 / 0.22 = Recommended Daily Amount

Recommended Daily Amount = 69 / 0.22 = 313.64 grams (rounded to one decimal place)

Step-by-step explanation:

You want the solution to √(2x+4) -√x = 2.

We eliminate the radicals by squaring until there aren't any. After the first squaring, we have to separate the radical term from the others.

  [tex]\sqrt{2x+4}-\sqrt{x}=2\\\\(2x+4)-2\sqrt{(2x+4)(x)}+(x)=4\qquad\text{square both sides}\\\\3x=2\sqrt{x(2x+4)}\qquad\text{add $\sqrt{x(2x+4)}-4$}\\\\9x^2=4(2x^2+4x)\qquad\text{square both sides}\\\\x^2-16x=0\qquad\text{subtract the right side from both sides}\\\\x(x -16) = 0\qquad\text{factor}[/tex]

The solutions to this are the values of x that make the factors zero. Those values are x=0 and x=16. Trying these in the original equation, we have ...

Step-by-step explanation:

The slope intercept form of a linear equation is expressed as: [tex]y=mx+b\text{ where }m\ne0[/tex]

The slope described how the y value changes as x changes. If it's positive then that means as x increases, y increases and if it's negative then that means as x increases, y decreases.

Knowing this information, there is only one reasonable option in this case. Given the equation: [tex]y=x+6[/tex], we know that it has a slope of positive one, meaning it's increasing. Given the equation: [tex]y=-\frac{3}{4}x+4[/tex], we know that it has a slope of negative three fourths, meaning it's decreasing.

The graph shown is increasing so option A is the only reasonable option in this case.

Step-by-step explanation:

To prove that OHAP is a square, we need to show that all four sides are congruent and all four angles are right angles.

Since AOB is a right isosceles triangle, we know that angle OAB and angle OBA are both congruent to 90 degrees, which means that they are both right angles. Since [OH] is the altitude relative to [AB], it bisects angle OAB, which means that angle AOH and angle HOA are both congruent to 45 degrees. Since P is the symmetric of H with respect to OA, we know that OA is congruent to OP, and we also know that OH is congruent to OP. Therefore, all four sides of OHAP are congruent, which means that OHAP is a square.

To solve for x in the equation A = 6x + 5, we can first subtract 5 from both sides, giving us A - 5 = 6x. This simplifies to A = 6x + 5. Dividing both sides by 6 gives us x = (A-5)/6.

Similarly, we can solve for x in the equation B = 4x + 45. Subtracting 45 from both sides gives us B - 45 = 4x, and dividing by 4 gives us x = (B-45)/4.

To find the measure of A, we can substitute the value of x that we found into the equation for A.

A = 6x + 5

A = (6 * (B-45)/4) + 5

A = (3/2) * B - 45/2 + 5

A = (3/2) * B + 5/2

So the measure of A is (3/2) * B + 5/2.

What is specialty fee in a project?

Specialty fee of a project is associated with the cost or money that is given for some special task for e.g. hiring a architect or other specialist.

To calculate the amount of money that will be spent on specialty fees, we need to multiply the total amount of money raised (35,000,000) by the specialty fee percentage (0.5%).

specialty fees = 35,000,000 * 0.005 = 175,000

So, $175,000 will be spent on specialty fees.

Also, To calculate the amount of money that will be spent on service commission, we need to multiply the total amount of money raised (35,000,000) by the service commission percentage (2%).

the circle standard form is

(x - h)² + (y - k)² = r²

r being the radius, (h, k) being the coordinates of the center.

fully multiplied that is

x² - 2hx + h² + y² - 2ky + k² = r²

we have here

4x² + 12x + 4y² - 40y - B = 0

our first step is to bring this back to an excision in x² and y². so, we divide everything by 4.

x² + 3x + y² - 10y - B/4 = 0

by comparing this to the general equation we see

3 = -2h

h = -3/2 = -1.5

-10 = - 2k

The subject matter of the math discipline of algebra is symbols and the arithmetic operations performed on them. Variable describes these symbols because they don't have any fixed values. We frequently notice values that are in constant flux in our day-to-day problems.

To represent these shifting values, however, is always necessary. These values are frequently represented in algebra with symbols like x, y, z, p, or q; these symbols are referred to as variables.

The gate code at your apartment complex is three numerical digits followed by # sign.



There are 10 digits (0 to 9).

Compute the number of possible gate codes if each code contains non-repeating digits as follows.

The first 3 place in the code must be filled by three non-repeating digits.

So, there are 10 possibilities for the first digit, 9 possibilities for the second digit and 8 possibilities for the third digit.

Hence, the three non-repeating digits can occur in 10×9×8 ways.

The three non-repeating digits are followed by "#" sign. The sign # can occur in only one way.
