40 is the median.

From median to upper quartile is 25% & form from upper quartile to maximum is 25%

So, 25 + 25 = 50 %

What is the solution to log Subscript 3 Baseline (x 12) = log Subscript 3 Baseline (5 x) x = negative 8 x = negative 3 x = 3 x =

FrozenT [24]

The product rule states that the multiplication of two or more logarithms with common bases is equal to adding the individual logarithms.

The value of x is 3.

Given

The following expression:

$\rm log_3(x+12)=log_3(5x)$

<h3>What properties for Logarithms are used to solve the equation?</h3>

The following properties are used in the logarithms equation given below.

The product rule states that the multiplication of two or more logarithms with common bases is equal to adding the individual logarithms.

The bases are equal, the arguments are also equal;

Therefore,

$\rm log_3(x+12)=log_3(5x)\\\\x+12=5x\\\\5x-x=12\\\\4x=12\\\\x=\dfrac{12}{4}\\\\x=3$

Hence, the value of x is 3.

Determine the slope between the points (5, -5) and (-1, 7)

meriva

Answer:

slope = 3

Step-by-step explanation:

5 - x1 -5 - y1

-1- x2 7 - y2

m= y2 - y1 / x2 - x1

m= 7 - (-5) / -1 -(-5)

m= 12 / 4

m= 3

generate a continuous and differentiable function f(x) with the following properties: f(x) is decreasing at x=−5 f(x) has a loca

garik1379 [7]

Answer:

see details in graph and below

Step-by-step explanation:

There are many ways to generate the function.

We'll generate a function whose first derivative f'(x) satisfies the required conditions, say, a quadratic.

1. f(x) has a local minimum at x = -3, and

2. a local maximum at x = 3

Therefore f'(x) has to cross the x-axis at x = -3 and x=+3.

Furthermore, f'(x) must be increasing at x=-3 and decreasing at x=+3.

f'(x) = -x^2+9

will satisfy the above conditions.

Finally f(x) must be decreasing at x= -5, which implies that f'(-5) must be negative.

Check: f'(-5) = -(-5)^2+9 = -25+9 = -16 < 0 so ok.

f(x) can then be obtained by integrating f'(x) :

f(x) = integral of -x^2+9 = -x^3/3 + 9x = 9x - x^3/3

A graph of f(x) is attached, and is found to satisfy all three conditions.

Ann spent $7.74 on oranges. If each orange costs $0.36 per pound, how many pounds of oranges did Ann buy?

solmaris [256]

Set variables for the quantities we want to find. Let x = number of applesLet y = number of oranges Next, we use these variables to write equations that describes the whole story. Since the total price is $7.75 and each type of fruit has their own price, we can say 0.40x + 0.35y = 7.55 The other equation will represent the total number of fruits bought all together, as Mark mentioned. Once you have those equations, you solve the system using substitution and elimination methods to solve for the variables x and y.
