Answer:

Third option

Step-by-step explanation:

-3(2x - 5) < 5(2 - x)

-6x + 15 < 10 - 5x <-- Third option

15 < 10 + x

5 < x

x > 5

There only appears to be one option. The solution to the inequality is x>5, not x<5.

1a. Sum of interior angles of a heptagon:

[tex]\displaystyle \sf \text{Sum of interior angles} = (7 - 2) \times 180^\circ = 900^\circ[/tex]

1b. Sum of interior angles of a 13-gon:

[tex]\displaystyle \sf \text{Sum of interior angles} = (13 - 2) \times 180^\circ = 1980^\circ[/tex]

2. Number of sides for a polygon with a sum of interior angles of 1260°:

[tex]\displaystyle \sf (n - 2) \times 180^\circ = 1260^\circ[/tex]

[tex]\displaystyle \sf n - 2 = \frac{1260^\circ}{180^\circ}[/tex]

[tex]\displaystyle \sf n - 2 = 7[/tex]

[tex]\displaystyle \sf n = 7 + 2 = 9[/tex]

Therefore, the sum of the measures of the interior angles of a heptagon is 900°, the sum of the measures of the interior angles of a 13-gon is 1980°, and the polygon with a sum of interior angles of 1260° is a nonagon (9-gon).

Answer:

1. a. 900°       b. 1980°

2. Nonagon

Step-by-step explanation:

In order to find the interior angles of a polygon, use the formula,

Sum of interior angles = (n-2)*180°

For

a. Heptagon

no of side =7

The sum of the interior angles of a heptagon:

(7-2)*180 = 900°

b. 13-gon

no. of side =13

The sum of the interior angles of a 13-gon:
(13-2)*180 = 1980°

2.

The sum of the interior angles of a convex polygon is 1260°,

where n is the number of sides.

In this case, we have

1260 = (n-2)*180

1260/180=n-2

n-2=7

n=7+2

n=9

Therefore, the polygon has 9 sides and is classified as a nonagon.

The exponential decay function that satisfies the given conditions is:

[tex]f(x) = 4 * (1/2)^x[/tex].

In this equation, the y-intercept is 4, which means that when x = 0, the function value is 4. As x increases by 1, the function decreases by a factor of one-half. This behavior is captured by raising 1/2 to the power of x in the equation.

The base of the exponent, 1/2, ensures that the function decreases exponentially. When x = 1, the exponent becomes 1, and[tex]1/2^1[/tex] equals 1/2. This means that the function value decreases to half of its previous value. Similarly, when x = 2, the exponent becomes 2, and[tex]1/2^2[/tex] equals 1/4. The function value decreases to one-fourth of its previous value, and so on.

By multiplying the exponential term by 4, we ensure that the y-intercept is 4. This scaling factor allows us to control the initial value of the function and match the given condition.

The exponential decay function[tex]f(x) = 4 * (1/2)^x[/tex] represents a decaying process where the y-values decrease exponentially as x increases, while starting at a y-intercept of 4.

Triangles A and C are similar, but not congruent to each other. Similar triangles have proportional sides and congruent angles, while congruent triangles have congruent sides and congruent angles.

Therefore, only B is correct

The question is asking for pairs of congruent triangles but lacks key information needed to accurately answer this, such as lengths or angles. Congruent triangles are identified in geometry based on either side-lengths or angles.

The question is about congruent triangles, which in mathematics means triangles that have the same size and shape. But to accurately answer which pairs show two congruent triangles, we need more information. The options provided include 'A', 'B', and 'C' but without knowing more about these elements (for example their lengths or angles), it is impossible to determine which are congruent. Congruent triangles are identified in geometry based on either side lengths (SSS: Side-Side-Side, SAS: Side-Angle-Side, ASA: Angle-Side-Angle) or angles (AAS: Angle-Angle-Side, HL: Hypotenuse-Leg for right triangles).

Step-by-step explanation:

(a) The amount for total expenditures in 2015 was about $63.2 billion.

(b) The first full year in which expenditures exceeded $110 billion was 2027.

(a) To find the amount for total expenditures in 2015, we need to substitute x = 20 into the function h(x) = [tex]23.4(1.08)^{(x-5)[/tex].

h(x) = 23.4(1.0[tex]8)^{(20-5)[/tex]

    = 23.4(1.0[tex]8)^{15[/tex]

    ≈ 23.4(2.717)

Rounding to the nearest tenth, the total expenditures in 2015 were about $63.2 billion.

(b) To determine the first full year in which expenditures exceeded $110 billion, we need to find the value of x when h(x) is greater than $110 billion.

110 = 23.4(1.0[tex]8)^{(x-5)[/tex]

Dividing both sides by 23.4:

4.7008547... = (1.0[tex]8)^{(x-5)[/tex]

Taking the logarithm base 1.08 of both sides:

log₁.₀₈(4.7008547...) = x - 5

Using a logarithm calculator or software, we find:

x - 5 ≈ 11.75

Adding 5 to both sides:

x ≈ 16.75

Rounding to the nearest whole number, the first full year in which expenditures exceeded $110 billion was 2027.

To find the experimental probability of rolling a number greater than 10, we need to determine the frequency of rolling a number greater than 10 and divide it by the total number of rolls.

Looking at the table, we can see that the frequency for rolling a number greater than 10 is the sum of the frequencies for rolling 11 and 12.

Frequency for rolling a number greater than 10 = Frequency of 11 + Frequency of 12

Frequency for rolling a number greater than 10 = 15 + 17 = 32

The total number of rolls is given as 200.

Experimental Probability of rolling a number greater than 10 = Frequency for rolling a number greater than 10 / Total number of rolls

Experimental Probability of rolling a number greater than 10 = 32 / 200

Experimental Probability of rolling a number greater than 10 = 0.16 or 16%

Therefore, the experimental probability of rolling a number greater than 10 is 16%.

The fraction of the container needed to fill up the gas tank of the lawn mower four times is 6/12. Option D.

The shaded part of the circle represents the fraction of gas needed to fill up the gas tank of the lawn mower once. To determine the fraction needed to fill it up four times, we can simply multiply the fraction by 4.

Let's assume that the shaded part of the circle represents x part of the whole container. Therefore, the fraction needed to fill up the gas tank of the lawn mower once is x.

To fill up the gas tank four times, we need to multiply x by 4. Therefore, the fraction needed to fill up the gas tank four times is 4x.

Now, we can compare this to the answer choices given:

8/48: This can be simplified to 1/6, which is not equal to 4x.

8/12: This can be simplified to 2/3, which is not equal to 4x.

6/16: This can be simplified to 3/8, which is not equal to 4x.

6/12: This can be simplified to 1/2, which is equal to 4x.

Step-by-step explanation:

The amount of medication needed for 30 days is approximately 59.84 tablets of carprofen.

To calculate the amount of carprofen medication needed for 30 days, we need to consider the prescribed dosage, the weight of the patient, and the concentration of the tablets.

The prescribed dosage is 2.2 mg/kg BID x 30d. This means that the patient should take 2.2 milligrams of carprofen per kilogram of body weight, twice a day, for 30 days.

The weight of the patient is 34 kilograms. So, we need to calculate the total amount of carprofen needed for the entire treatment period.

First, we calculate the daily dosage by multiplying the weight of the patient (34 kg) by the prescribed dosage (2.2 mg/kg).

Daily dosage = 34 kg * 2.2 mg/kg = 74.8 mg/day.

Since the medication is prescribed twice a day, we multiply the daily dosage by 2 to get the total dosage per day.

Total dosage per day = 74.8 mg/day * 2 = 149.6 mg/day.

Finally, to find the total amount of medication needed for 30 days, we multiply the total dosage per day by the number of days.

Total medication needed = 149.6 mg/day * 30 days = 4488 mg.

Since the concentration of the tablets is 75 mg, we divide the total medication needed by the tablet concentration to find the number of tablets required.

Number of tablets needed = 4488 mg / 75 mg = 59.84.

A "⊂-maximal element" in set theory refers to an element in a set that cannot be strictly contained within any other element of the set, indicating a maximum extent or boundary within that set.

In the context of set theory and Tarski's notion of finiteness, a "⊂-maximal element" refers to an element within a set that cannot be strictly contained within any other element of the set. Let's break down the meaning of this term.

Consider a set S and a partial order relation ⊆ (subset relation) defined on the power set P(S) of S. A "⊂-maximal element" u of a set A ⊆ S is an element that is not strictly contained within any other element of A with respect to the subset relation. In other words, there is no element v in A such that u is a proper subset of v.

Formally, for any u ∈ A, if there is no v ∈ A such that u ⊂ v, then u is a ⊂-maximal element of A. This means that u is as large as possible within A and cannot be extended by including additional elements.

In the context of T-finite sets, the existence of a ⊂-maximal element in every nonempty subset of the set guarantees that the set has a well-defined structure and does not continue indefinitely without boundaries.

It ensures that there is a definitive maximum element within each subset, which is a key characteristic of finiteness.

Consider the following counterexample:

[tex]A = \begin{bmatrix} 1 & 0 \ 0 & 1 \end{bmatrix}\\B = \begin{bmatrix} 1 & 0 \ 0 & 0 \end{bmatrix}[/tex]

Both matrices A and B are invertible, as they are both identity matrices. However, when we multiply them together, we get:

[tex]AB = \begin{bmatrix} 1 & 0 \ 0 & 0 \end{bmatrix}[/tex]

The rank of AB is 1, not n. In this case, n = 2, but rank(AB) = 1. Therefore, the statement "rank(AB) = n" is not always true for all invertible n by n matrices A and B with rank(A) = rank(B) = n.

In general, the rank of the product AB is less than or equal to the minimum of the ranks of A and B. So, in order for rank(AB) to be equal to n, both A and B need to have rank n individually, but that does not guarantee the rank of their product to be n as well.

therefore

x^2 + 10x +23 = 0

c=23

note we use the coefficients only.

Answer:

y = π/3

Step-by-step explanation:

To find the value of y, we can use the trigonometric identity for the sum of angles:

sin(x + y) = sin x * cos y + cos x * sin y

Comparing this with the given equation:

sin(x + y) = 1/2(sin x) + √3/2(cos x)

We can equate the corresponding terms:

sin x * cos y = 1/2(sin x) ----(1)

cos x * sin y = √3/2(cos x) ----(2)

From equation (1), we can see that cos y = 1/2.

From equation (2), we can see that sin y = √3/2.

To determine the values of y, we can use the trigonometric values of cosine and sine in the first quadrant of the unit circle.

In the first quadrant, cos y is positive, so cos y = 1/2 corresponds to y = π/3 (60 degrees).

Similarly, sin y is positive, so sin y = √3/2 corresponds to y = π/3 (60 degrees).

Therefore, the value of y is y = π/3 (or 60 degrees).
