The domain of a function is the set of numbers over which the function is defined, and the range of the function is the set of values that the function can take when being evaluated at the elements of the domain.

On a graph, the domain can be identified as the values over the X-axis where the graph is drawn, and the range can be identifies as the values over the Y-axis where the graph is drawn.

On the graph, notice that all values from 0 to 6, including 0 but not 6, belong to the domain.

Similarly, on the graph, al vallues from 6.3 to 9.5, not including 6.3 but including 9.5, belong to the range.

Then, the domain of the function is the interval:

The range of the function is the interval:

Answer: A. H0: Mean= 5 and Ha: Mean is not equal to 5.

Step-by-step explanation:

Definitions:

Given: The diameter of a spindle in a small motor is supposed to be 5.8 millimeters.

If the spindle is either too small or too large, the motor will not work properly. so, Mean diameter ≠ 5.8 to work correctly.

i.e. \(H_a: \text{Mean}\neq 5.8\)

So, \(H_a: \text{Mean =5.8}\)

The required null and alternative hypotheses:

H0: Mean= 5 and Ha: Mean is not equal to 5.

The mathemematical sum of the three numbers 1+1+1 would give 3

Addition of numbers can involve 2 or more values using the additive sign '+'. For any given sum of values, the result obtained would be greater than any of the individual value in the sum.

Here, 1 + 1 + 1 means that we are adding 1 in three places. The value obtained would be 3.

In the range of 0° x 360°, the trigonometric formula 2.cos(2x) = 7.cos(x) has two solutions: x = 104.5° or 255.5°.

The trigonometric equation 2.cos(2x) = 7.cos(x) is given in the question, and we are asked to get x given that 0° <  x < 360°.

According to trigonometric identities, cos(2θ) = 2.cos²(θ) - 1.

We may solve the following expression as follows by using this identity:

2.cos(2x) = 7.cos(x),

or 2{2.cos²(x) - 1} = 7.cos(x),

or, 4.cos²(x) - 2 - 7.cos(x) = 0.

To create a quadratic equation, we replace cos(x) with k, yielding 4k² - 7k - 2 = 0.

This problem can be solved as follows:

4k² - 7k - 2 = 0,

or, 4k² - 8k + k - 2 = 0,

or, 4k(k - 2) + 1(k - 2) = 0,

or, (4k + 1)(k - 2) = 0.

The zero-product rule allows us to demonstrate that

Either, 4k + 1 = 0, implies that k = -1/4,

Or, k - 2 = 0, implies that k = 2 are true.

Since k stands for cos(x), its value cannot be 2, as we know that -1 <  cos(θ) < 1.

So, cos(x) = k = -1/4 is what we got.

Using this, we can write that

in the range 0° < x < 360°, x = cos⁻¹(-1/4) = 104.5° or 255.5°.

Thus, x = 104.5° or 255.5° is the answer to the trigonometric formula 2.cos(2x) = 7.cos(x) in the range 0° x 360°.

The interest rate required to get a total amount, principal plus interest, of $11,430.00 from simple interest on a principal of $9,000.00 over 3 years is 9% per year.

We can use the simple interest formula to solve this problem:

I = P × r × t

Where I is the interest earned, P is the principal (initial amount), r is the interest rate, and t is the time in years.

We know that Connor had $11,430 in the account after 3 years, and he had initially deposited $9,000. So the interest earned is:

Interest = accrued amount - principal

I = $11,430 - $9,000

I = $2,430

Substituting the values we have into the formula, we get:

I = P × r × t

$2,430 = $9,000 × r × 3

Simplifying, we get:

r = $2,430 / ($9,000 × 3)

r = 9/100

r = 0.09

R = r × 100%

R = 0.09 × 100%

R = 9%

Therefore, the interest rate for Connor's savings account is 9%.

Jessica has the higher score because her z score on the SAT is 1.05, which is greater than Ashley's z score on the ACT, which is 1.02.

Jessica scores 1830 on the SAT.

Ashley scores 27 on the ACT.

Assuming that both tests measure the same thing, then we have to determine who has the higher score.

Consider the z-score for Jessica's SAT score of 1830.

z = (x - μ)/σ

z = (1830 - 1498)/316

z = 332/316

z = 1.05

Consider z for Ashley, who has an ACT score of 27.

z = (27 - 21.5)/5.4

z = 5.5/5.4

z = 1.02

Answer:

Los números son:

6 y 5

Step-by-step explanation:

Planteamiento:

a * b = 30

a + b = 11

Desarrollo:

De la segunda ecuación del planteamiento:

a = 11-b    

Sustituyendo esta última ecuación en la primer ecuación del planteamiento:

(11-b)*b = 30

11*b + b*-b = 30

11b - b² - 30 = 0

-b² + 11b - 30 = 0

b = {-11±√((11²)-(4*-1*-30))} / (2*-1)

b = {-11±√(121-120)} /-2

b = {-11±√1} / -2

b = {-11±1} / -2

b₁ = {-11-1} / -2 = -12/-2 = 6

b₂ = {-11+1} / -2 = -10/-2 = 5

Comprobación:

6*5 = 30

6+5 = 11

Therefore, the equation of the line passing through the point (1,5) with a slope of 7 is y = 7x - 2.

The equation of a line in the point-slope form is given by the following equation:

y-y_1 = m(x-x_1)

where m is the slope of the line and (x1, y1) is any point on the line.

Therefore, we can write the equation of the line passing through the point (1,5) with a slope of 7 as follows:

y-5 = 7(x-1)

Expanding the right-hand side of the equation gives:

y-5 = 7x-7

Adding 5 to both sides of the equation gives:

y = 7x-2

b) The equation of the parabola is y = x² + 4x + 96 with vertex ( -2 , 92 ) and the y intercept is ( 0 , 96 ) and the axis of symmetry is x = -2

What is a Parabola?

A Parabola, open curve, a conic section produced by the intersection of a right circular cone and a plane parallel to an element of the cone. A parabola is a plane curve generated by a point moving so that its distance from a fixed point is equal to its distance from a fixed line

The equation of the parabola is given by

( x - h )² = 4p ( y - k )

where ( h , k ) is the vertex and ( h , k + p ) is the focus

y is the directrix and y = k – p

The equation of the parabola is also given by the equation

y = ax² + bx + c

where a , b , and c are the three coefficients and the parabola is uniquely identified

Given data ,

a)

Let the equation be represented as A

Now , the value of A is

Let the number be = n

A = Two-fifth of the sum of a number and 24 is equal to 5 times the number decreased by 18

Substituting the values in the equation , we get

2/5 ( n + 24 ) = 5n - 18

On simplifying the equation , we get

Multiply by 5 on both sides of the equation , we get

2 ( n + 24 ) = 25n - 90

2n + 48 = 25n - 90

Subtracting 2n on both sides of the equation , we get

23n - 90 = 48

Adding 90 on both sides of the equation , we get

23n = 138

Divide by 23 on both sides of the equation , we get

n = 6

Therefore , the number is 6

b)

The equation of parabola is given as

y = x² + 4x + 96

Now , the equation can be simplified as

y = (x + 2)² + 92

The equation of the parabola is given by

( x - h )² = 4p ( y - k )

where ( h , k ) is the vertex and ( h , k + p ) is the focus

Substituting the values in the equation , we get

The vertex of the parabola is P ( -2 , 92 )

The y intercept of the parabola is ( 0 , 96 )

The axis of symmetry of parabola is x = -2

Hence , the equation of parabola is y = (x + 2)² + 92
