Answer:

"B".  Domain is all real numbers, and the Range is all positive real numbers

Step-by-step explanation:

It is important to recognize that this function is an exponential function, either by the graph (observe a horizontal asymptote on the x-axis, and increasing exponentially), or more importantly by the equation which is in exponential form \(y=a*b^x\) where "a" is a non-zero real number, and "b" is a positive real number not equal to 1.

Observe that for the given function, a=4 (a real number not equal to zero), and b=2 (a positive real number that is not 1).

The domain for all exponential functions is all real numbers, so this function's domain is all real numbers.

The Range for exponential functions depends on "a", where if "a" is a positive number the Range is positive numbers only, and if "a" is a negative number, the Range is negative numbers only.

Since "a" is positive, the Range is positive numbers only.

Writing the Domain in "set-builder notation" (since all of the choices are given using that notation), the Domain is "all real numbers" put into curly brackets, so {all real numbers}.

Writing the Range in "set-builder notation", recall that the Range is the outputs of the function, so the Range is "y values such that y is greater than zero".  There is some shorthand used, where the phrase "such that" is symbolized using a short vertical line (common in set-builder notation), and the phrase "y is greater than zero" is shortened using inequality symbols "y>0".  So, the Range is written as { y | y>0 }.

Further, the "Domain" and "Range" are abbreviated with "D" and "R" respectively.

Therefore, the final answer would be D = {all real numbers}; R = { y | y>0 }, which is answer "B"

Inverse variation equation:

The equation is:

Answer:

y = -39/x

Step-by-step explanation:

Formula we use,

→ y = k/x

→ k = xy

Now the value of k will be,

→ k = xy

→ k = 13 × (-3)

→ [ k = -39 ]

Then the inverse equation is,

→ y = k/x

→ -3 = -39/13

→ [ y = -39/x ]

Hence, the answer is y = -39/x.

Step-by-step explanation:

The binomial factors of x³- 4x²+x+6​ are (x+2), (x+3), and (x-1).

Using the splitting and grouping the terms:

x³ + 4x² + x - 6

= x³ + 2x² + 2x² + x - 6  [Splitting 4x² = 2x² + 2x²]

= (x³ + 2x²) + (2x² + x - 6)

= x² (x + 2) + (2x² + 4x - 3x - 6)

= x² (x + 2) + [ 2x (x + 2) - 3 (x + 2)]

= x² (x + 2) + (x + 2) (2x - 3)

= (x + 2) ( x² + 2x - 3)

= (x + 2) ( x² + 3x - x - 3)

= (x + 2) [x (x + 3) - 1 (x + 3)]

= (x + 2) (x + 3) (x - 1)

Hence, the binomial factors are (x + 2), (x + 3) and (x - 1)

Answer:

C....

Step-by-step explanation:

Solution :

Let \(p_1\) and \(p_2\)  represents the proportions of the seeds which germinate among the seeds planted in the soil containing \(3\%\) and \(5\%\) mushroom compost by weight respectively.

To test the null hypothesis \(H_0: p_1=p_2\) against the alternate hypothesis  \(H_1:p_1 \neq p_2\) .

Let \(\hat p_1, \hat p_2\) denotes the respective sample proportions and the \(n_1, n_2\) represents the sample size respectively.

\($\hat p_1 = \frac{74}{155} = 0.477419\)

\(n_1=155\)

\($p_2=\frac{86}{155}=0.554839\)

\(n_2=155\)

The test statistic can be written as :

\($z=\frac{(\hat p_1 - \hat p_2)}{\sqrt{\frac{\hat p_1 \times (1-\hat p_1)}{n_1}} + \frac{\hat p_2 \times (1-\hat p_2)}{n_2}}}\)

which under \(H_0\)  follows the standard normal distribution.

We reject \(H_0\) at \(0.05\) level of significance, if the P-value \(<0.05\) or if \(|z_{obs}|>Z_{0.025}\)

Now, the value of the test statistics = -1.368928

The critical value = \(\pm 1.959964\)

P-value = \($P(|z|> z_{obs})= 2 \times P(z< -1.367928)$\)

                                     \($=2 \times 0.085667$\)

                                     = 0.171335

Since the p-value > 0.05 and \($|z_{obs}| \ngtr z_{critical} = 1.959964$\), so we fail to reject \(H_0\) at \(0.05\) level of significance.

Hence we conclude that the two population proportion are not significantly different.

Conclusion :

There is not sufficient evidence to conclude that the \(\text{proportion}\) of the seeds that \(\text{germinate differs}\) with the percent of the \(\text{mushroom compost}\) in the soil.

We know that:Reynold's number (Re) = ρv(d₁ + d₂)/2νWhere, ρ = density of oil = SG × 10³ kg/m³Now,Re = ρv(d₁ + d₂)/2ν= (0.9 × 10³ kg/m³) × (400 × 10⁻³ m/s) × (70 + 70.2)/2 × (1/0.005)≈ 50404.8(As Re > 2000, laminar flow is present)Coefficient of Viscosity (C) = 3/4μ(c/d₁ + d₂)

Answer:

(x - 1) (x^2 + 4x + 53)

Step-by-step explanation:

Common factor: x - 1

(x^3 + 3x^2+ 49x - 53) / (x - 1)

= (x^2 + 4x + 53) (x-1)

Using L'hopital we can see that the limit is equal to 1/22

Here we want to take the limit of x tending to zero for x/sin(22x)

Notice that when x = 0, both numerator and denominator are zero, so we need to take the limit of the first derivatives, for:

y = x

y' = 1

And for:

y = sin(22x)

y' = 22*cos(22x)

Now taking the limit we will get:

\(\lim_{x \to 0} \frac{1}{22cos(22x)} = \frac{1}{22cos(0)} = 1/22\)

That is the value of the limit.

Answer:

I can explain how to complete each of the steps you have provided.

1. Draw a point at (1, -2)

This is a simple step. Just mark a dot on your paper at the coordinates (1, -2).

2.

Draw an 8-unit long radius

Using your compass, set the radius to 8 units. Place the compass on the point you drew in step 1 and draw a circle around it, making sure that the radius is 8 units long.

3. Using a compass

Draw a circle with your point from step one as your center and the point from step two as the side: This step is already completed in step 2.

4. Using a protractor draw a 70 degree arc

Place your protractor on the center of the circle (the point you drew in step 1) and draw a 70 degree arc on the circle.

5. Draw a central angle which intercepts your arc

Use a straight edge to draw a line from the center of the circle to each endpoint of the arc you drew in step 4. This creates a central angle, which is an angle whose vertex is at the center of the circle and whose sides intercept the circle.

6. Draw an inscribed angle which intercepts a 40 degree arc

Use a straight edge to draw a line from one endpoint of the 70 degree arc to the other endpoint. Then, draw a perpendicular bisector of this line, which intersects the center of the circle. This creates a 40 degree arc on the circle. Draw a line from the center of the circle to one endpoint of the 40 degree arc, and draw a line from that endpoint to the other endpoint of the 40 degree arc. This creates an inscribed angle, which is an angle whose vertex is on the circle and whose sides intercept the circle.

7. Draw a tangent line

Choose a point on the circle that is not on the 70 degree arc. Draw a line from that point tangent to the circle.

8. Draw a secant line

Choose two points on the circle that are not on the 70 degree arc. Draw a line through those points, which intersects the circle at two points.

9. Equation of your circle

The equation of a circle with center (a,b) and radius r is (x-a)^2 + (y-b)^2 = r^2. Using the coordinates of the center from step 1 and the radius from step 2, the equation of the circle is (x-1)^2 + (y+2)^2 = 64.

The required length of the third side of the right-angle triangle is 15 units.

In a right-angled triangle, its sides, such as the hypotenuse, are perpendicular and the base is Pythagorean triplets.

Here,
For the right triangle lenght of the two legs to be 9 and 12 units, a measure of the third side is to be determined.

So, Applying the Pythagoras theorem,
h² = p² + b²
h = √9² + 12²
h = √225
h = 15

Thus, the required length of the third side of the right-angle triangle is 15 units.

From the dot plot, the lowest value shown is 0, so statement a is true.

b. The maximum is 12.5.

From the  data, the highest value shown is 12, not 12.5. Hence false statement

c. The midrange is 11.

The midrange would be (0 + 12) / 2 = 6.

Therefore, this statement  is false.
