how do we get the coefficient for the each term? well, the first coefficient is 1, and all subsequents are "the product of the current coefficient and the exponent of the first element divided by the exponent of the second element on the next term", so, that's a mouthful, but for example,

for the 5th term of the expansion, how did we get 210?  well, is just 120 * 7 / 4.

for the 6th term, how did we get 252?  well, is just 210 * 6 / 5.

recall that if the exponent is 10, that means the expansion will be 11 terms, and therefore the middle term will be the 6th one.

so, just combine the 6th term away.

If you know that a full marathon is about (1.4X10^5) feet, then you can just divide that by 2. To get the most accurate answer on a calculator make sure to put that value in parenthesis before dividing it. I got 70,00. Hope this helped!

Answer:

Length of half marathon = 7 x 10⁴ feet

Step-by-step explanation:

Length of marathon is given as 1.4 x 10⁵ feet

            Length of full marathon = 1.4 x 10⁵ feet

Length of half marathon is half the length of full marathon.

[tex]\texttt{Length of half marathon = }\frac{\texttt{Length of full marathon}}{2}\\\\\texttt{Length of half marathon = }\frac{1.4\times 10^5}{2}=0.7\times 10^5\\\\\texttt{Length of half marathon = }7\times 10^4feet[/tex]

Length of half marathon = 7 x 10⁴ feet

Final answer:

To find the probability that the drone will fly less than 4.66 hours, calculate the z-score and look up the corresponding probability in the standard normal distribution. A z-score of -2.5 indicates a probability of about 0.62%.

Explanation:

To calculate the probability that the drone will fly less than 4.66 hours, we need to convert the flight time of 4.66 hours into a z-score. The z-score represents how many standard deviations an element is from the mean.

The formula to calculate the z-score is:

Z = (X - μ) / σ

Where:
X = Value we're interested in (4.66 hours)
μ = Mean (4.76 hours)
σ = Standard deviation (0.04 hours)

Calculating the z-score:

Z = (4.66 - 4.76) / 0.04 = -2.5

Now, we look up the z-score in the standard normal distribution table or use a calculator to find the probability to the left of that z-score, which gives us the probability that the drone will fly less than 4.66 hours. Typically, a z-score of -2.5 corresponds to a probability of approximately 0.0062 or 0.62%.

Therefore, the probability that the drone will fly less than 4.66 hours is about 0.62%.

she will have a total of $180

The answer is:  $ 180 .

General integral for volume using washer method:
[tex]V = \pi \int_a^b (R^2 - r^2) dx[/tex]

First determine limits along x-axis.
region is bounded by x=1 and x=-1, so the limits are also -1 and 1.

Next determine R(x) and r(x)
R is the long radius, which is distance from x-axis to upper bound.
The upper bound of region is y = sec(x).
R = sec(x)

r is the short radius, which is distance from x-axis to lower bound.
The lower bound is y = 1.
r = 1

Sub into integral:
[tex]V = \pi \int_{-1}^1 (sec^2 x - 1) dx[/tex]

Integrate
[tex]V = \pi |_{-1}^1 (tan x - x)[/tex]

Evaluate
[tex]V = \pi[(tan(1) -1) - (tan(-1) +1)] \\ \\ V = 2\pi(tan(1) -1) \\ \\ V = 3.502[/tex]

Final answer:

We are finding the volume of a solid obtained by rotating a region bounded by specific curves about the x-axis. This involves the method of disk washers and the calculation of an integral. However, the calculation is impossible with this exact set of curves due to the undefined values at x = π/2 and x = -π/2.

Explanation:

To answer your question, let's first understand what is happening. We are taking the region between the curves y=sec(x), y=1, x=-1, and x=1 and rotating it about the x-axis. This creates a type of solid shape called a solid of revolution. We can find the volume of such a shape using the method of cylindrical shells or disk washers.

The volume V of the solid obtained by rotating about the x-axis the region confined by the given curves is given by the formula:

V = ∫ (from a to b) π [R(x)² - r(x)²] dx

where R(x) is the distance from the x-axis to the outer curve (y=sec(x)), and r(x) is the distance from the x-axis to the inner curve (y=1).

However, calculating the integral ∫ (from -1 to 1) π [sec(x)² - 1] dx directly can be difficult because the function sec(x) is undefined at x = π/2 and x = -π/2.

A typical way around such difficulties is to use a suitable trigonometric substitution, but in this case, the function sec(x) is periodic with a period of 2π, so we can't avoid these points, both of which lie in the interval from -1 to 1. Hence, it is impossible to find the volume of the solid as stated by rotating about the x-axis the region between the curves y = sec(x), y = 1, x = -1, and x = 1.

Yes the treasury can determine whether the gold bar is really weighing 500 ounces.

We can use the equation:

7 x + 11 y = 500

where x is the amount of the 7 ounce weights while y is the amount of 11 ounce weights.

 

We know that x and y should be whole numbers therefore this is solved through trial and error.

By trial and error I got:

x = 7 and y = 41

So that;

7 * 7 + 11 * 41 = 500

49 + 451 = 500

500 = 500

 

Hence they can use 41 11-ounce weights and 7 7-ounce weights to test

The statement "a sample of n = 9 scores is randomly selected from a population with m = 80 and s = 9 is false.

What is a normal distribution?

It's the probability curve of a continuous distribution that's most likely symmetric around the mean. On the Z curve, at Z=0, the chance is 50-50. A bell-shaped curve is another name for it.

It is given that:

A sample of n = 9 scores is randomly selected from a population with m = 80 and s = 9.

As we know,

Z = (x - u)/s

Z = 3

x = 83

s = 9

3 = (83 - u)/9

27 = 83 - u

u = 83 - 27 = 56

Thus, the statement "a sample of n = 9 scores is randomly selected from a population with m = 80 and s = 9 is false.

33 + 10 + 12 - 15 - 33 = 7°F

Answer:

Fall 7°F

Step-by-step explanation:

A digit is a number in one of the places, so for example the number 54 has two digits; a tens place digit (5) and a ones place digit (4).

Say the mystery number is a two digit number = xy
* that's not x times y but two side by side digits.

Info given:
the sum of the digits of a two-digit number is 6
x + y = 6
if the digits are reversed, yx the difference between the new number and the original number is 18.

**To obtain the number from digits you must multiply by the place and add the digits up. (Example: 54 = 10(5) + 1(4))

Original number = 10x + y
Reversed/New number = 10y + x

Difference:
10y + x - (10x + y) = 18
9y - 9x = 18
9(y - x) = 18
y - x = 18/9
y - x = 2

Now we have two equations in two variables
y - x = 2
x + y = 6

Re-write one in terms of one variable for substitution.
y = 2 + x
sub in to the other equation to combine them.
x + (2 + x) = 6
2x + 2 = 6
2x = 6 - 2
2x = 4
x = 2

That's the tens digit for the original number. Plug this value into either of the equations to obtain y, the ones digit.

2 + y = 6
y = 4

number "xy" = 24

In a proportional relationship, the value of the constant of proportionality is always equal to the ratio of the x and y for a directly proportional relationship and is equal to the product of x and y for an inversely proportional relationship.

Since am wants to write an equation to represent a proportional relationship with a constant of proportionality of 6. Therefore, the equation can be written as,

Slope intercept form & in standard form , passes through (1, 7) , perpendicular to 3x + 7y = 1

Turn 3x + 7y = 1 into slope-intercept form.

Remember, slope-intercept form is : y=mx+b where m=slope & b=y-intercept.

To turn out given equation into slope-intercept form, we must get x & y onto different sides.

So, subtract 3x from both sides.

7y = -3x + 1

Then, divide both sides by 7.

y = -3/7x + 1/7

Remember, when an equation is perpendicular to another equation, both equations have negative reciprocals. 

m₁=-3/7 & m₂=7/3

Our new equation has these things in it :

A slope of 7/3 & it passes through (1, 7)

So, simply plug these into the slope-intercept equation.

y=mx+b

y = 7/3x + 7 → (a)Slope-intercept form 

Now we must put this into (b)standard form.

Standard form is :  Ax+Bx=C

So, we just use our slope-intercept form, but rearrange it :)

y = 7/3x + 7

In standard form, x & y are on the same side, so we simply subtract 7/3x from both sides.

-7/3x + y = 7 → (b)Standard Form

Final answer:

To find the lower sum, divide the interval into subintervals, evaluate the function at the left endpoint of each subinterval, and sum up the areas of the rectangles with those minimum values as heights.

Explanation:

To approximate the area of the region using lower sums, we need to calculate the lower sum by dividing the interval into subintervals of equal width, finding the minimum value of each subinterval, and summing up the areas of the rectangles with those minimum values as heights.

In this case, we have the function y = sqrt(1-x^2). Let's say we divide the interval into n subintervals. The width of each subinterval would be (b-a)/n, where a and b are the lower and upper limits of the interval.

To find the minimum value of each subinterval, we can evaluate the function at the left endpoint of each subinterval. Let's call these points x1, x2, x3,..., xn. Then, the lower sum is given by: Lower Sum = (b-a)/n * (f(x1) + f(x2) + f(x3) + ... + f(xn)).

To check if the lower sums you calculated are correct, make sure you are using the left endpoints of the subintervals and that the calculation is accurate.

and the negative angle is -5pi/18 - 36pi/18  = -41pi/18

The answer is  b

Final answer:

To find the coterminal angles with -5π/18, we have to add or subtract multiples of 2π. By doing so, we find out that the coterminal angles are −23π/18, 13π/18, and -41π/18. So, the correct option is c.

Explanation:

To find angles that are coterminal with a given angle, we have to add or subtract multiples of 2π. This is because a full rotation around the unit circle is 2π radians. Angles that differ by an exact multiple of 2π radians are considered as coterminal.

Therefore, we can get the coterminal angles of −5π/18 by adding and subtracting multiples of 2π. This gives us the angles, −23π/18 and 13π/18 (for positive angles) and −41π/18 (for a negative angle). Thus, the option (c) −23π/18, 13π/18, 31π/18 is correct.
