Answer:

  D.  15(cos(23π/12) +i·sin(23π/12))

Step-by-step explanation:

You want the product 5(cos(π/4 +i·sin(π/4))×3(cos(5π/3) +i·sin(5π/3)).

The product is ...

  A·cis(a) × B·cis(b) = AB·cis(a+b)

where "cis(x)" means (cos(x) +i·sin(x))

  5·cis(π/4) × 3·cis(5π/3) = (5·3)·cis(π(1/4+5/3)) = 15·cis(23π/12)

The product is 15·(cos(23π/12) +i·sin(23π/12)).

Alternatively, if we want to solve for r in terms of h, we can rearrange the equation as follows: r = h - 35

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants.

Let h be the height of the railing from the ground and let r be the height of the ramp from the ground.

We are given that the railing is 35 inches above the ramp, which means that the total height of the railing from the ground is h = r + 35.

So the equation that represents the situation is:

h = r + 35

Answer: We have the equation:

24,816,000 = x / 10^5

To solve for x, we can multiply both sides by 10^5:

24,816,000 * 10^5 = x

Using a calculator or long multiplication, we can simplify this to:

2,481,600,000,000 = x

Therefore, 24,816,000 is equal to 2,481,600,000,000 divided by 10 to the fifth power.

Step-by-step explanation:

Step-by-step explanation:

A trapezoid is a quadrilateral with one pair of parallel sides.

The median of a trapezoid connects the midpoint of the non-parallel sides.

IJ is the median of the trapezoid. I is the midpoint of EH, and J is the midpoint of GF.

Also, the median of a trapezoid is also parallel to the parallel sides. IJ║ HG║ EF.

(The proof of this is extensive and requires drawing additional lines such as HJ and extending EF further until HJ and EF intersect at another point, Y. It is given as the other diagram. You also need prior knowledge of the midsegment of a triangle.)

The measure of the midsegment of a trapezoid, by definition, is also equal to the average of the measure of the parallel segments.

In the figure,

[tex]IJ=\dfrac{(HG+EF)}{2}[/tex]

Substituting the values we have, HG = 8, EF = 12 gives us:

[tex]IJ=\dfrac{(HG+EF)}{2}[/tex]

[tex]IJ=\dfrac{(8+12)}{2}[/tex]

[tex]IJ=\dfrac{20}{2}[/tex]

It can be estimated that approximately 3,042 people in attendance would prefer ketchup on a hot dog.

Thus, the correct answer is 3,042.

To determine how many people in attendance would prefer ketchup on a hot dog based on the data from the sample, we need to calculate the proportion of people who prefer ketchup and apply it to the total attendance.

The sample indicates that out of 150 people surveyed:

54 people prefer ketchup

36 people prefer relish

60 people prefer chili

To find the proportion of people who prefer ketchup, we divide the number of people who prefer ketchup by the total number of people surveyed:

Proportion of people who prefer ketchup = 54 / 150 = 0.36

Now, to estimate the number of people in attendance who would prefer ketchup on a hot dog, we multiply the proportion calculated above by the total attendance:

Estimated number of people who prefer ketchup = 0.36 [tex]\times[/tex] 8,450 = 3,042

The simplified cos(t)/sec(t) to the trig function 1 - sin²(t), which is equivalent to cos²(t).

Recall that the secant function is defined as the reciprocal of the cosine function. In other words, sec(t) = 1/cos(t). Therefore, we can rewrite cos(t)/sec(t) as cos(t)/(1/cos(t)).

To simplify this expression, we can multiply both the numerator and the denominator by cos(t), which gives:

cos(t)/(1/cos(t)) = cos(t) * (cos(t)/1) = cos²(t)

Now, we have simplified cos(t)/sec(t) to cos²(t). Alternatively, we could have used the identity cos²(t) = 1 - sin²(t) to simplify the expression. This identity follows directly from the Pythagorean identity cos²(t) + sin²(t) = 1.

Starting with cos(t)/sec(t), we can substitute sec(t) = 1/cos(t) to get:

cos(t)/sec(t) = cos(t)/(1/cos(t)) = cos²(t)/1

Then, we can use the identity cos²(t) = 1 - sin²(t) to substitute cos²(t) in terms of sin(t):

cos(t)/sec(t) = cos²(t)/1 = (1 - sin²(t))/1 = 1 - sin²(t)

So, we have simplified cos(t)/sec(t) to the trig function 1 - sin²(t), which is equivalent to cos²(t).

Answer: 6.28 cm

Step-by-step explanation:

The equation of ellipse with foci (2, 4) and (2, -8) and co-vertices (10, -2) and (-6, -2) is ((x - 2)^2 / 64) + ((y + 2)^2 / 36) = 1

To find the equation of the ellipse, we first need to determine the center of the ellipse. Since the foci are on the same vertical line, the center of the ellipse is at the midpoint of the segment connecting the foci.

The midpoint of the segment connecting the foci is:

((2+2)/2, (4-8)/2) = (2, -2)

So the center of the ellipse is (2, -2).

Next, we need to determine the lengths of the semi-major and semi-minor axes. The semi-major axis is half the distance between the co-vertices, which is:

a = (10 - (-6))/2 = 8

The semi-minor axis is half the distance between the foci, which is:

c = (4 - (-8))/2 = 6

Now we can use the standard form of the equation of an ellipse centered at (h,k):

((x - h)^2 / a^2) + ((y - k)^2 / b^2) = 1

where a is the length of the semi-major axis and b is the length of the semi-minor axis.

Plugging in the values we have:

((x - 2)^2 / 8^2) + ((y + 2)^2 / 6^2) = 1

Simplifying and rearranging:

((x - 2)^2 / 64) + ((y + 2)^2 / 36) = 1

So the equation of the ellipse is:

((x - 2)^2 / 64) + ((y + 2)^2 / 36) = 1

Step-by-step explanation:

1. In the calculation, only one pound of fish food is shared equally among one aquarium.

2. Each of the aquarium gets one pound of fish food

To solve the first part of the problem, we need to find the value of P when 1/2 ÷ 8 = P. By doing the calculation by hand, we get:

1/2 ÷ 8 = 0.0625. So, the  P = 0.0625.

In the second part of the problem, we know that 1 pound of fish is shared equally among a certain number of aquariums, and we need to find that number.

Since each aquarium gets 1 pound of fish food, and the total amount of fish food is 1 pound, we can set up an equation to solve for the number of aquariums:

1 pound of fish food / X number of aquariums = 1 pound of fish food per aquarium

Simplifying the equation, we get:

X = 1 pound of fish food / 1 pound of fish food per aquarium

X = 1 aquarium

Therefore, the pound of fish food is shared equally among 1 aquarium, and each aquarium gets 1 pound of fish food.

An exponential function is a function in which the independent variable x appears as an exponent.

a is the y-intercept.

b is the rate of change and common ratio.

The function is exponential growth when b > 1.

The function is exponential growth when b < 1.

y-intercept is the initial value of the function when x is equal to 0.

Asymptote is the line that the function approaches but does not cross.

In Mathematics, an exponential function is typically represented by the following mathematical expression:

f(x) = a(b)^x

Where:

Based on the given exponential function y = a(b)^x, we can logically deduce that the y-intercept is represented by a, b is the rate of change, and common ratio.
