The measure of the value of x from the figure is 62

Vertical angles are angles that are equal and meet at a point of intersection X. Given the following measure of angles;

<M1 =. 2x - 8

<M3 = 116 degrees

Since the measure of both angles are the same hence;

2x - 8 = 116

Add 8 to both sides

2x - 8 + 8 = 116 + 8

2x = 116 + 8

2x = 124

Divide both sides by 2

2x/2 = 124/2

x = 124/2

x = 62

Hence the measure of the value of x from the figure is 62

Ludlow's z-score is z = 13.5

Given that the heights of American men are approximately normal.

Mean of the population, μ = 69.3 inches

Standard Deviation of the population, σ = 2.8 inches

Height of Robert Ludlow is 8 feet 11.1 inches = 107.1 inches [since 1 feet = 12 inches and 8 feet = 96 inches. 96 + 11.1 = 107.1 inches]

So [tex]\bar x[/tex] = 107.1 inches.

Since the population is assumed to be normal, we can find the z-score,

z = [tex]\frac{\bar x-\mu}{\sigma}[/tex]

  = (107.1-69.3)/2.8  

  = 37.8 / 2.8

The constraints that are suitable for the situation are x≥4y , 7.50x+4.75y≤125 , x>0 and y>0 .

In the question it is given that

"x" represent the number of yellow rosebushes.

"y" represent the number of red rosebushes.

The word "at least' means "≥".

So "at least 4 times as many yellow rosebushes as red rosebushes" means x≥4y .  (constraint 1)

The number of red or yellow rosebushes cannot be negative .

So , x>0 (constraint 2)

y>0   (constraint 3)

Also ,

the cost of each yellow rosebushes = $7.50

number of yellow rosebushes = x

total cost of yellow rosebushes =7.50x

the cost of each red rosebushes = $4.75

number of yellow rosebushes = y

total cost of yellow rosebushes =4.75y

According to the question ,

she can spend no more than $125  , that means

7.50x+4.75y≤125  ( constraint 4)

Therefore , the constraints that are suitable for the situation are x≥4y , 7.50x+4.75y≤125 , x>0 and y>0 .

IR x ≠ ± [tex]\sqrt{-3}[/tex]

Points of discontinuity - x = ± [tex]\sqrt{-3}[/tex]  ( non removable / asymptote )

x - intercept = ± 1 , y -  intercept = -1/3

Any function that can be expressed as a polynomial divided by a polynomial is said to be rational. The domain of a rational function is the set of all numbers except the zeros of the denominator since polynomials are defined everywhere. First example: f(x) = x/ (x - 3).

y=x²-1/x²+3

Answer:

2 ≤ x ≤ 3 where x represents the number of hours walking

Step-by-step explanation:

The distance to walk in miles can be modeled as the following inequality

Let x represent the number of hours Blake will be walking.

To cover 10 mi at 5 mph, Blake will take 10/5 = 2 hours
To cover 15 mi at 5 mph, Blake will take 15 /5 = 3 hours

The actual number of hours walked must lie within these limits

So

2 ≤ x ≤ 3 where x represents the number of hours walking

The solution for the given equation (log 3 x=1) is and  the nearest ten-thousandth = 3.3333333.

Begin by identifying the base, which is "b" within equation, the exponent, which would be "y," and the exponential expression, which is "x." Then, shift the exponential expression with one side of the equation and apply the exponential to the base by multiplying it by itself a number of times.

Given  log 3 x=1

this can be written as log₁₀(3x) = 1

so,

log₁₀(3x) = 1

Applying the log rule we get:

3x = 10

Using the Pythagorean Theorem, we have that the distance from home plate to second base is about 127 feet.

The Pythagorean Theorem relates the length of the legs [tex]l_1[/tex] and [tex]l_2[/tex] of a right triangle with the length of the hypotenuse h, stating that the hypotenuse squared is the sum of the legs squared of the triangle, according to the following equation:

[tex]h^2 = l_1^2 + l_2^2[/tex]

The distance between each consecutive base is of 90 feet, hence the distance from home plate to 2nd base is the hypotenuse of a right triangle in which the legs are of 90 feet, being the distances from home plate to 1st base and 1st base to 2nd base.

Then:

h² = 90² + 90²

h = sqrt(90² + 90²)

h = 127 feet.

The distance from home plate to second base is about 127 feet.

The steps to express a fraction as a decimal is the reverse of the steps required to write a decimal as a fraction, with the resulting fraction being simplified further as follows;

To write a decimal as a fraction gives a fraction having all the digits of the decimal up to the last nonzero digit in the numerator, and 10 raised to the power, the number of places to the decimal point is moved up to the right of the last non zero digit, and vice versa.

Starting from question 2, we have;

The functions are f(x) = 5x-1 and g(x) = [tex]\frac{x+1}{5}[/tex].

We have to find two functions such that their composition gives the identity function.

That is, we need to find functions f and g such that f(g(x)) = x.

Also f(g(x)) = (f o g)(x)

A function g is said to be the inverse of a function f if, (f o g)(x) = f(g(x)) = x, for all real numbers x.

So  in short if we take f(x) any function then we should find its inverse function.

Let f(x) = 5x - 1.

Then take y = 5x - 1.

⇒ x =  [tex]\frac{y+1}{5}[/tex]

That is if we take g(x) = [tex]\frac{x+1}{5}[/tex], then,

If a scientist has 315 cells in a container and she expects the number of cells to triple in one day then the number of cells the scientist will have after one day is equal to 945.

The number of cells the scientist will have after one day can be figured out using multiplication. Multiplication is one of the four parts of arithmetic. It can be considered as the opposite of division and can be defined as the repeated addition of the same number or groups of equal sizes.

The number of cells the scientist will have after one day can be calculated as follows;

Number of cells = 315

As it is expected to triple, which means that it is expected to increase three times in amount.

Therefore;

3 × number of cells in the container

3 × 315 = 945

Hence, the number of cells the scientist will have after one day is calculated to be 945.
