Option B) The cat weighs 4 kilograms when it is 7 months old.  is the correct answer.

A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Each function has a range, codomain, and domain.

Given, w gives the weight of the cat, in kgs, when it is "m" months old.

Since w gives weight in kilograms. It outputs weight when we tell the age in months,

thus,

w(7) means weight when the cat is 7 months old.

and w(7) = 4 represents that the cat weighs 4 kilograms when the age of the cat is 7 months.

Therefore, Option B) At 7 months old, the cat weighs 4 kg. is the right response.

Answer:

218.57

Step-by-step explanation:

Since it is an isoceles triangle, the sides are 32, 32, and 14.

Using Heron's Formula, which is Area = sqrt(s(s-a)(s-b)(s-c)) when s = a+b+c/2,  we can calculate the area.

(A+B+C)/2  = (32+32+14)/2=39.

A = sqrt(39(39-32)(39-32)(39-14) = sqrt(39(7)(7)(25)) =sqrt(47775)= 218.57.

Hope this helps have a great day :)

Check the picture below.

so let's find the height "h" of the triangle with base of 14.

\(\begin{array}{llll} \textit{using the pythagorean theorem} \\\\ a^2+o^2=c^2\implies o=\sqrt{c^2 - a^2} \end{array} \qquad \begin{cases} c=\stackrel{hypotenuse}{32}\\ a=\stackrel{adjacent}{7}\\ o=\stackrel{opposite}{h} \end{cases} \\\\\\ h=\sqrt{ 32^2 - 7^2}\implies h=\sqrt{ 1024 - 49 } \implies h=\sqrt{ 975 }\implies h=5\sqrt{39} \\\\[-0.35em] ~\dotfill\)

(a) When performing an ANOVA with the data the alternative hypothesis is at least two of the restaurants have different mean delivery times.

(b)75.8

Analysis of variance. or ANOVA, is a statistical method that separate observed variance data into different components to use for additional tests. A one way ANOVA is used for three or more groups of data, to gain information about the relationship between the dependent and independent variables.

The ANOVA table shows how the sum of squares are distributed according to source of variation, and hence the mean sum of squares.

It is given that a pizza lover wants to compare the average delivery times.

Therefore the null hypothesis and alternate hypothesis implies that,

H₀ =  all restaurants have equal mean delivery time

Hₐ = at least two restaurants have different two deliveries

Hence the alternate hypothesis for performing an ANOVA with the data is at least two of the restaurants have different mean delivery times.

The alternate hypothesis (Hₐ) defines that there is a statistically important relationship between two variables. Whereas null hypothesis states that is no statistical relationship between the two variables.

Therefore, the 300th term of the sequence is 2748. The correct choice is option A: 2748.

To find the 300th term of the sequence using the explicit formula, we need to identify the first term (a1) and the common difference (d).

Looking at the given sequence:

57, 66, 75, 84, 93, ...

We can see that the first term (a1) is 57, and the common difference (d) is 66 - 57 = 9.

Now, we can use the explicit formula to find the 300th term (a300):

an = a1 + (n - 1) * d

Substituting the values:

a300 = 57 + (300 - 1) * 9

a300 = 57 + 299 * 9

a300 = 57 + 2691

a300 = 2748

Answer:

18 values for n are possible.

Step-by-step explanation:

Given the quadratic polynomial:

\($x^2 - mx + n$\)

such that:

Roots are positive prime integers and

\($m < 20$\)

To find:

How many possible values of \(n\) are there ?

Solution:

First of all, let us have a look at the sum and product of a quadratic equation.

If the quadratic equation is:

\(Ax^{2} +Bx+C\)

and the roots are: \(\alpha\) and \(\beta\)

Then sum of roots, \(\alpha+\beta = -\frac{B}{A}\)

Product of roots, \(\alpha \beta = \frac{C}{A}\)

Comparing the given equation with standard equation, we get:

A = 1, B = -m and C = n

Sum of roots,  \(\alpha+\beta = -\frac{-m}{1} = m\)

Product of roots, \(\alpha \beta = \frac{n}{1} = n\)

We are given that \(m<20\)  

\(\alpha\) and \(\beta\) are positive prime integers such that their sum is less than 20.

Let us have a look at some of the positive prime integers:

2, 3, 5, 7, 11, 13, 17, 23, 29, .....

Now, we have to choose two such prime integers from above list such that their sum is less than 20 and the roots can be repetitive as well.

So, possible combinations and possible value of \(n (= \alpha \times \beta)\) are:

\(1.\ 2, 2\Rightarrow n = 2\times 2 = 4\\2.\ 2, 3 \Rightarrow n = 6\\3.\ 2, 5 \Rightarrow n = 10\\4.\ 2, 7\Rightarrow n = 14\\5.\ 2, 11 \Rightarrow n = 22\\6.\ 2, 13 \Rightarrow n = 26\\7.\ 2, 17 \Rightarrow n = 34\\8.\ 3, 3\Rightarrow n = 3\times 3 = 9\\9.\ 3, 5 \Rightarrow n = 15\\10.\ 3, 7 \Rightarrow n = 21\\\)

\(11.\ 3, 11\Rightarrow n = 33\\12.\ 3, 13 \Rightarrow n = 39\\13.\ 5, 5 \Rightarrow n = 25\\14.\ 5, 7 \Rightarrow n = 35\\15.\ 5, 11 \Rightarrow n = 55\\16.\ 5, 13 \Rightarrow n = 65\\17.\ 7, 7 \Rightarrow n = 49\\18.\ 7, 11 \Rightarrow n = 77\)

So,as shown above 18 values for n are possible.

The equation of the line which is passing to a point and slope 2/3 will be y = 2/3x + 5.

It is possible to determine a line's direction and steepness by looking at its slope. Finding the slope between lines inside a coordinate plane can aid in anticipating if the lines are perpendicular, parallel, or none at all without physically using a compass.

As per the given information in the question,

The equation for the line in the slop form is,

y = mx + b

Slope, m = 2/3

y = 2/3x + b, it is representing a partial equation.

Substitute the given point (3, 7) in the above equation,

7 = (2 ×3)/3 + b

b = 7 - 2

b = 5

So, the equation of the line will be,

y = 2/3x + 5.

Answer:

The answer is d

The ordered pair lie on the inverse of the function is (62,−3).

Option A is the correct answer.

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

f(x) = -(x - 1)³ - 2

The inverse of f(x).

y = -(x - 1)³ - 2

interchange x and y and solve for y.

x = -(y - 1)3 - 2

(y - 1)³ = -2 - x

(y - 1)³ = -(2 + x)

Cuberoot on both sides.

y - 1 = ∛-(2 + x)

y = ∛-(2 + x) + 1

Now,

Substitute in the inverse of g(x).

(62, -3) = (x, y)

(−4, 123) = (x, y)

(3, 1) = (x, y)

(3,−6) = (x, y)

So,

y = ∛-(2 + x) + 1

y = ∛-(2 + 62) + 1

∛-1 = -1

y = -1∛64 + 1

y = -1 x 4 + 1

y = -4 + 1

y = -3

So,

(62, -3) ______(1)

And,

y = ∛-(2 + x) + 1

y = ∛-(2 - 4) + 1

∛-1 = -1

y = ∛(-2 + 4) + 1

y = ∛2 + 1

y =  1.26 + 1

y = 2.26

So,

(-4, 2.26) _______(2)

And,

y = ∛-(2 + x) + 1

y = ∛-(2 + 3) + 1

∛-1 = -1

y = -1∛5 + 1

y = -1 x 1.71 + 1

y = -1.71 + 1

y = -0.71

So,

(3, -0.71) _______(3)

And,

y = ∛-(2 + x) + 1

y = ∛-(2 + 3) + 1

∛-1 = -1

y = -1∛5 + 1

y = -1 x 1.71 + 1

y = -1.71 + 1

y = -0.71

So,

(3, -0.71) ______(4)

Thus,

From (1), (2), (3), (4) we see that,

(62, -3) is the solution to the inverse of g(x).

Answer: B

Answer:

its a c and d

Step-by-step explanation:

The rate constant for the first-order reaction is approximately 0.035 s⁻¹. The correct answer is B

To find the rate constant in units of s⁻¹ for a first-order reaction, we can use the relationship between the half-life (t1/2) and the rate constant (k).

The half-life for a first-order reaction is given by the formula:

t1/2 = (ln(2)) / k

Given that the half-life is 20 minutes, we can substitute this value into the equation:

20 = (ln(2)) / k

To solve for the rate constant (k), we can rearrange the equation:

k = (ln(2)) / 20

Using the natural logarithm of 2 (ln(2)) as approximately 0.693, we can calculate the rate constant:

k ≈ 0.693 / 20

k ≈ 0.03465 s⁻¹

Therefore, the rate constant for the first-order reaction is approximately 0.0345 s⁻¹. The correct answer is B
