Answer:

B 1/4

Step-by-step explanation:

f(x) = y = x⁴ + 5

the inverse function is

y - 5 = x⁴

x = 4th root(y - 5)

now we rename y and x to make it a regular function definition :

g(x) = y = ±4th root(x - 5) = ±(x - 5)^(1/4)

because g(6) = 1 (positive), we have

g(x) = (x - 5)^(1/4)

and since we are using the positive branch, it means also that all the tangent slopes (= g'(x)) are positive.

g'(x) = 1/4 × (x - 5)^(-3/4) × 1 = 1/4 × (x - 5)^(-3/4)

because (x - 5)' = 1

g'(6) = 1/4 × (6 - 5)^(-3/4) = 1/4 × (1/1³)^(1/4) =

= 1/4 × 1^(1/4) = 1/4 × 1 = 1/4

please note, we are using only the positive root result in this case to get a positive result as tangent slope for g(x) as enforced by g(6) = 1.

The speed of the output shaft is 182 rpm.

Given:

Gear index i = 0.33

Input speed = 60 rpm.

Let output shaft speed is x.

we know that:

gear index = [tex]\frac{n_{in} }{n_{out} }[/tex]

i = 60/x

0.33 = 60/x

x = 60/0.33

= 60/033/100

= 60*100/33

= 6000/33

= 181.818 ≈ 182 rpm.

Therefore The speed of the output shaft is 182 rpm.

Answer:

u = 2

Step 1: Simplify both sides of the equation.

−7u −u +2u +11u = 10

−7u +−u +2u +11u = 10

(−7u +−u +2u +11u) = 10 (Combine Like Terms)

5u = 10

Step 2: Divide both sides by 5.

5u/5 = 10/5

The measure of the angle that isn't labeled are:

∠B = 100

∠K = 100

∠L = 41

∠M = 86

The angles that are in the same position on two parallel lines intersected by a transversal line on the parallel lines.

Corresponding angles are equal.

We have,

Two congruent figures.

Each figure's total sum of the angles must be 360.

The figures are congruent so the corresponding angles must be equal.

From the first figure we get,

∠A = 133 ( Corresponding angles )

∠A + ∠B + ∠C + ∠D = 360

133 + ∠B + 41 + 86 = 360

∠B = 360 - 260

∠B = 100

Now,

∠k = ∠B = 100

∠L = ∠C = 41

∠M = ∠D = 86

Thus,

The measure of the angle that isn't labeled are:

∠B = 100

Step-by-step explanation:

The probability of a type I error is 0.022.

Given,

It is not always possible to identify rare diseases by screening. A blood test that has been created by researchers is thought to be reasonably dependable. In 97% of those who suffer from a sickness, it produces a favorable response. However, 5% of those tested receive an incorrectly positive response because they do not have the condition.

The null hypothesis is given as "the individual does not have the disease".

We have to find the probability of type l error if the new blood test is used;

Here,

A: The individual does not have the disease

B: The individual does have the disease

We know that,

Type I Error is rejecting the true null hypothesis

Then, probability;

P (Type I Error) = P(Positive reaction to an individual who does not have the disease)  = 0.022

Step-by-step explanation:

(i)

using Pythagoras' identity in the right triangle

the square on the hypotenuse is equal to the sum of the squares on the other 2 sides , that is

(k + x)² = m² + (k - x)² ← expand factors on both sides using FOIL

k² + 2kx + x² = m² + k² - 2kx + x² ( add 2kx to both sides )

k² + 4kx + x² = m² + k² + x² ( subtract k² + x² from both sides )

4kx = m² ( divide both sides by 4k )

x = [tex]\frac{m^2}{4k}[/tex]

----------------------------------------------------------

(ii)

the area A of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

here b = m and h = k - x

A = [tex]\frac{1}{2}[/tex] m (k - x) ← substitute x = [tex]\frac{m^2}{4k}[/tex]

  = [tex]\frac{1}{2}[/tex] m ( k - [tex]\frac{m^2}{4k}[/tex] ) ← distribute parenthesis

  = [tex]\frac{mk}{2}[/tex] - [tex]\frac{m^3}{8k}[/tex]  ← express as a single fraction

  =  [tex]\frac{4mk^2-m^3}{8k}[/tex] ← factor out m from each term in the numerator

As far as I know, all Samsung themselves say is to restart your phone to try your luck. An app crashing or some form of corrupt media may have caused your photos to go missing. There may, however, still be a small chance that the photos are there, somewhere on your phone, you just can't find them.
