The variable d represents the number of days he spends on vacation, and the variable p represents the total number of postcards he buys Cooper will have bought a total of 18 postcards after 2 days of vacation.

If p = 9d represents the total number of postcards Cooper buys in relation to the number of days he spends on vacation, we can substitute d = 2 into the equation to find the total number of postcards he buys after 2 days of vacation:

p = 9d

p = 9(2)  [Substitute d = 2]

p = 18

Therefore, Cooper will have bought a total of 18 postcards after 2 days of vacation.

Therefore , the solution of the given problem of probability comes out to be pizza won't be a cheese pizza is roughly 0.7089, or 70.89%.

Any considerations technique's fundamental objective is to determine the likelihood that a claim is true or that a particular incident will take place. Any number range from one to one, when 0 traditionally signifies a percentage and 1 typically implies the degree of certainty, can be used to represent chance. A probability illustration shows the likelihood that a particular event will occur.

Here,

The total number of pizzas made yesterday can be determined using the information provided as follows:

2121 cheese pizzas total.

Pizzas with vegetables: 1414

2323 pepperoni pizzas total.

1414 sausage pizzas were consumed.

Total pizzas produced were

=>2121 + 1414 + 2323 + 1414 = 7272.

Therefore, there were 2121 cheese pizzas prepared yesterday out of a total of 7272 pizzas.

The likelihood that the following pizza will be a cheese pizza is calculated as follows:

=> 2121 / 7272

The likelihood that the next pizza prepared won't be a cheese pizza is thus:

=> 1 - (2121 / 7272) = 5151 / 7272

Therefore, a conservative estimate of the likelihood that the following pizza won't be a cheese pizza is roughly 0.7089, or 70.89%.

The inflection occurs at x = n*pi, while the absolute extreme points, while the critical points can be found with the expression 5 + 5cos(x) = 0.

To find local extreme points, absolute extreme points, and inflection points, we will first take the first and second derivatives of the function.

y = 5x + 5sin(x)

y' = 5 + 5cos(x)

y'' = -5sin(x)

To find critical points, we set the first derivative equal to zero.

5 + 5cos(x) = 0

cos(x) = -1

x = pi

This is the only critical point, so we only need to evaluate the function at x = pi to find any extreme points.

y(pi) = 5pi - 5

So the absolute minimum occurs at (pi, -5).

To find inflection points, we set the second derivative equal to zero.

-5sin(x) = 0

sin(x) = 0

x = k*pi, where k is an integer.

The area of the shaded region is 88π square inches.

To find the area of the shaded region, we need to subtract the area of the inner circle (with a radius of 9 inches) from the area of the outer circle (with a radius of 13 inches).

The area of a circle is given by the formula A = πr^2, where r is the radius.

Area of outer circle = π * (13²) = 169π square inches

Area of inner circle = π * (9²) = 81π square inches

Area of shaded region = Area of outer circle - Area of inner circle

= 169π - 81π

= 88π square inches

So, the area of the shaded region is 88π square inches.

Boat is 4.195 miles or  6.749755 km far from the lighthouse B.

The boat has moved 4 kilometers from point A to point x. The distance between B and x is what we're looking for.

Trigonometry can be used to overcome this issue. Let's abbreviate the distance "d" from A to x. Then, we can apply the following formula:

tan(65°) = (9 / d)

We can rearrange this formula to solve for d:

d = 9 / tan(65°)

We find that:

tan(65°) = 2.1445

So, d = 9 / 2.1445

= 4.195 miles (rounded to the nearest tenth)

The value after solving mixed fraction is 32/10=3.2

A fraction is a metric unit for describing a piece or component of a whole. It represents the appropriate parts of the totality. A fraction is made up of two parts: the numerator and the denominator. The number at the top is the numerator, and the number at the bottom is the denominator. The numerator indicates the number of equal parts that were actually taken, whereas the denominator shows the total number of equal parts in the whole.

The quotient and remainder of a fraction are used to represent it, making it a mixed fraction. For instance, 2 1/3, where 2 is the quotient and 1 is the remainder, is a mixed fraction. A mixed fraction is a combination of a whole number and a recognised fraction.

The value of 5 1/10 minus 1 9/10 is 16/5 or 3 1/5.

It is a mixed fraction when the remainder and quotient of a fraction are utilised to represent it. A mixed fraction is, for instance, 2 1/3, where 2 is the quotient and 1 is the remainder. A whole number and a recognised fraction are combined to form a mixed fraction.

To subtract mixed numbers like 5 1/10 and 1 9/10, you need to convert them to improper fractions first.

5 1/10 can be converted to an improper fraction as follows:

5 1/10 = (5 x 10 + 1)/10 = 51/10

1 9/10 can be converted to an improper fraction as follows:

1 9/10 = (1 x 10 + 9)/10 = 19/10

Now we can subtract the two fractions:

51/10 - 19/10 = (51 - 19)/10 = 32/10

32/10 can be simplified to 16/5 by dividing both the numerator and denominator by the greatest common factor, which is 2.

Answer:

Step-by-step explanation:

The Unit Circle is a circle with a radius of 1 unit that is centered at the origin of a coordinate plane. It is often used in trigonometry to understand the relationships between angles, coordinates, and trigonometric functions such as sine, cosine, and tangent.

Special angles in trigonometry are angles that have commonly used values for their trigonometric functions. These special angles are 0 degrees, 30 degrees, 45 degrees, 60 degrees, and 90 degrees, and their corresponding angles in radians (which are the preferred units for angles in the Unit Circle). These angles have well-defined coordinates on the Unit Circle, and their sine, cosine, and tangent values can be easily determined.

To find the coordinates of points on the Unit Circle for special angles, we can use the following steps:

Start with the angle in radians. For example, if we are finding the coordinates for the angle of 30 degrees, we convert it to radians by multiplying by the conversion factor pi/180 (since there are pi radians in 180 degrees): 30 degrees * (pi/180) = pi/6 radians.

Identify the coordinates on the Unit Circle that correspond to the angle in radians. For example, for an angle of pi/6 radians, we know that it is located in the first quadrant of the Unit Circle, and the coordinates of the point where the angle intersects the Unit Circle are (cos(pi/6), sin(pi/6)).

Use the values of cosine and sine for the special angle from trigonometric tables or from memory. For example, the cosine of pi/6 radians is sqrt(3)/2, and the sine of pi/6 radians is 1/2.

Substitute the cosine and sine values into the coordinates of the Unit Circle. For example, for the angle of 30 degrees or pi/6 radians, the coordinates on the Unit Circle are (cos(pi/6), sin(pi/6)) = (sqrt(3)/2, 1/2).

Use the tangent function to find the tangent value of the special angle. The tangent function is defined as the ratio of sine to cosine: tan(theta) = sin(theta) / cos(theta). For example, for the angle of pi/6 radians, the tangent value is (sin(pi/6)) / (cos(pi/6)) = (1/2) / (sqrt(3)/2) = 1/sqrt(3).

In summary, special angles in trigonometry are used to determine the coordinates of points on the Unit Circle, and the sine, cosine, and tangent values of these special angles can be found using trigonometric tables or from memory, and then applied to the Unit Circle to determine the coordinates and trigonometric function values for these angles.

Answer:

a) 3/4

b) 21/4  

Step-by-step explanation:

To find the scale factor from A to B take any side of B and divide it by the corresponding side of A

The ratio will be the same for all sides

We have
scale factor = 3/4

We see that the sides 9 and 12 are also in this ratio: 9/12 = 3/4

a) So scale factor from A to B is 3/4

b) w of shape B corresponds to the side with length 7 in shape A

The ratio of w to 7 must be equal to the scale factor

So w/7 = 3/4

w = 7 x 3/4

w = 21/4

The probability of picking a prime number is 2/3 or approximately 0.667.

What is probability?

Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 means the event is impossible and 1 means the event is certain to happen. The probability of an event can be calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

Out of the given options of 2, 3, and 4, only 2 and 3 are prime numbers. Therefore, the probability of picking a prime number is:

P(prime) = number of prime options / total number of options

P(prime) = 2/3

So the probability of picking a prime number is 2/3 or approximately 0.667.
