Answer:

a) 24/36 = 2/3 = w/6, so w = 4 inches

The maximum length of this postcard is 6 inches since the width is 4 inches.

b) 24/36 = 2/3 = w/11.5, so w = 7.67 inches

(won't work)

24/36 = 2/3 = 6.125/l, so

l = 9.1875 inches

The maximum width of this postcard is 6.125 inches since the length is 9.1875 inches.

Step-by-step explanation:

The mean is 78

   87 is 9 points above the mean

      this is   9 / 6.5  = + 1.39  standard deviations above the mean

                     z -score =+ 1.39 which represents .9177 ( from table )

or    91.77% scored LESS than this

           the remaining 8.23% scored HIGHER than this

                     8.23% * 25 students = .0823 * 25 = ~ 2 students

The sides of the right triangle are

hypotenuse = 8.6 km

the other leg = 3.1 km

the other angle = 21°25'

The sides of the right triangle are solved using the given details

The third angle say A is solved by

third angle = 180 - 90 - 68°35'

third angle = 21°25'

The sides, a

tan 21°25' = a / 8

a = 8 * tan 21°25'

a = 3.13

a = 3.1

The hypotenuse (say c) is solved by

c = √(a² + b²)

c = √(3.1² + 8²)

c = √(73.61)

c = 8.58

c = 8.6

The form of the general solution depends on the nature of the equations and the techniques used to solve them.

Here we have

dx/dt = 7x + y and dy/dt = -2x + 5y

To find the general solution of the given system of differential equations:

=> dx/dt = 7x + y  __ (1)

=> dy/dt = -2x + 5y  __(2)

Solve it using the method of simultaneous equations.

Solve Equation (1) for y:

y = dx/dt - 7x

Substitute the value of y in Equation (2):

dy/dt = -2x + 5(dx/dt - 7x)

Simplify the equation:

dy/dt = 5dx/dt - 2x - 35x

dy/dt = 5dx/dt - 37x

By constructing these arcs and connecting the appropriate points, we ensure that the newly drawn line passing through point C is parallel to line AB. Remember to use a straightedge to draw the lines accurately and ensure that the arcs intersect correctly.

To construct a line that passes through point C and is parallel to line AB, the best next step is to use a compass to mark an arc centered at point C that intersects line AB at two distinct points.

Here are the steps:

1) Take a compass and set its width to a convenient distance.

2) Place the compass point on point C and draw an arc that intersects line AB at two different points, let's call them D and E.

3) With the compass width still set, place the compass point on point D and draw an arc that intersects the previously drawn arc.

4) Without changing the compass width, place the compass point on point E and draw another arc that intersects the previous arc.

The width of a rectangular frame with a total area of 140 square inches, we set up an equation using the expressions for the length and width, simplify it, solve for x, and substitute the value of x into the expression for the width.

To solve for the width of a rectangular frame with a total area of 140 square inches, we first need to set up an equation using the given expressions for the length and width.
The formula for the area of a rectangle is length x width. Therefore, we can write:
(2x + 10)(2x + 6) = 140
We can then simplify this equation by expanding the expressions in the parentheses:
4x^2 + 32x + 60 = 140
Next, we can move all the terms to one side and simplify further:
4x^2 + 32x - 80 = 0
Now, we can solve for x by factoring or using the quadratic formula. After finding the value of x, we can substitute it into the expression for the width (2x + 6) to get the final answer.

To find half of the time that Arnold skied without falling, we first need to know how much time he spent skiing in total and how many times he fell. Let's assume that Arnold skied for a total of T minutes and fell F times. Then the time that Arnold skied without falling is (T - F * f), where f is the average time it takes Arnold to get up and start skiing again after a fall.

To find half of the time that Arnold skied without falling, we can simply divide (T - F * f) by 2. Let's call this value H. Then we have:

H = (T - F * f) / 2

To compare Arnold's skiing time with that of other family members who did not fall, we need to make some assumptions. Let's assume that each family member skied for a total of T minutes, and that some of them did not fall at all. Let's call the time that each family member skied without falling Ti.

Then we can write the following inequalities to compare Arnold's skiing time with that of others:

Arnold's skiing time without falling (H) is greater than or equal to the skiing time without falling of any family member Ti who fell at least once:

H >= Ti

Answer: The word "symbolism" contains 9 letters. To find the number of distinguishable ways to rearrange these letters, we can use the formula for the number of permutations of n objects, which is n! (n factorial).

However, in this case, there are repeated letters, specifically "s" and "m". To account for this, we need to divide the total number of permutations by the factorials of the number of times each repeated letter appears.

The letter "s" appears twice, so we divide by 2!. Similarly, the letter "m" also appears twice, so we divide by 2!.

Therefore, the number of distinguishable ways to rearrange the letters in the word "symbolism" is:

9! / (2! × 2!) = 362,880 / 4 = 90,720

So there are 90,720 distinguishable ways to rearrange the letters in the word "symbolism".

The solution is: the approximate surface area of the cone is 103.6 in², which is closest to option (B).

To find the exact surface area of the cone, we need to know the slant height of the cone. Since we are not given the slant height, we can use the Pythagorean theorem to find it:

Slant height² = h² + r²

Slant height² = 4² + 3²

Slant height² = 16 + 9

Slant height² = 25

Slant height = 5

Now that we know the slant height, we can use the formula for the surface area of a cone:

Surface area = πr² + πr×s

where s is the slant height

Surface area = π(3²) + π(3)(5)

Surface area = 9π + 15π

Surface area = 24π

Therefore, the exact surface area of the cone is 24π square units.

The surface area of a cone is given by:

Surface area = πr² + πr×s

where r is the radius of the circular base and s is the slant height.

We are given that the diameter of the circular base is 6 inches, so the radius is 3 inches. We are also given that the slant height is 8 inches. Using these values, we can calculate the surface area of the cone:

Surface area = π(3²) + π(3)(8)

Surface area = 9π + 24π

Surface area = 33π

We can approximate π as 3.14, so:

Surface area ≈ 33(3.14)

Surface area ≈ 103.62

Therefore, the approximate surface area of the cone is 103.6 in², which is closest to option (B).

To prove the identity sinh(2x) = 2 sinh(x) cosh(x), we can use the definitions of sinh(x) and cosh(x) and apply trigonometric identities for exponential functions.

We start with the left-hand side of the identity, sinh(2x). Using the definition of the hyperbolic sine function, sinh(x) = (e^x - e^(-x))/2, we can substitute 2x for x in this expression, giving us sinh(2x) = (e^(2x) - e^(-2x))/2.

Next, we focus on the right-hand side of the identity, 2 sinh(x) cosh(x). Again using the definitions of sinh(x) and cosh(x), we have 2 sinh(x) cosh(x) = 2((e^x - e^(-x))/2)((e^x + e^(-x))/2).

Expanding this expression, we get 2 sinh(x) cosh(x) = (e^x - e^(-x))(e^x + e^(-x))/2.

By simplifying the right-hand side, we have (e^x * e^x - e^x * e^(-x) - e^(-x) * e^x + e^(-x) * e^(-x))/2.

This simplifies further to (e^(2x) - 1 + e^(-2x))/2, which is equal to the expression we derived for the left-hand side.

Hence, we have proved the identity sinh(2x) = 2 sinh(x) cosh(x) by showing that the left-hand side is equal to the right-hand side through the manipulation of the exponential functions.

The degrees of freedom in this case are three, which means that the data has been divided into four categories. The exact interpretation of the chi-square value depends on the significance level. If the significance level is 0.05, which is commonly used, then the calculated chi-square value is greater than the critical value of 7.815.

This means that the null hypothesis of no difference between the observed and expected frequencies can be rejected at the 0.05 level of significance.

When the depth reaches 8 inches, the rate at which the grain level is rising is approximately (15 / (2 * sqrt(3))) ft/min.

To find the rate at which the grain level is rising when the depth reaches 8 inches, we can consider the volume of the grain in the trough and its rate of change with respect to time.

The trough is in the shape of an equilateral triangle, so the cross-sectional area of the trough at any depth can be calculated using the formula: A = (sqrt(3)/4) * s^2, where s is the length of the side of the equilateral triangle.

In this case, the length of the side of the equilateral triangle is 2 feet, so the cross-sectional area of the trough is A = (sqrt(3)/4) * 2^2 = sqrt(3) square feet.

Given that the trough is 8 feet long, the volume V of the grain in the trough at any depth h can be calculated as V = A * h.

Now, let's differentiate both sides of the equation with respect to time t to find the rate at which the volume is changing: dV/dt = d(Ah)/dt.

Since the length of the trough remains constant, dh/dt represents the rate at which the depth is changing.

Therefore, dV/dt = A * (dh/dt).

We are given that the grain is poured into the trough at a rate of 5 cubic feet per minute, so dV/dt = 5 ft^3/min.

At the depth of 8 inches (or 8/12 = 2/3 feet), we want to find the rate at which the grain level is rising, which is dh/dt.

Plugging in the known values, we have: 5 = (sqrt(3) * h) * (dh/dt).

Simplifying the equation, we find: dh/dt = 5 / (sqrt(3) * h).

Substituting h = 2/3 (depth in feet), we can calculate the rate at which the grain level is rising.

dh/dt = 5 / (sqrt(3) * (2/3)) = 5 / (sqrt(3) * 2/3) = 5 / (2 * sqrt(3) / 3) = 5 * 3 / (2 * sqrt(3)) = (15 / (2 * sqrt(3))) ft/min.
