The answer to the work shown is x = 8.

The law of indices are laws that has to be applied to expressions involving powers or fractions. These laws have individual application.

Considering the given question, we have;

16^(3x - 6) = 64^(x + 4)

It can be deduced that, the factors of;

16 = 4 x 4

   = 4^2

and

64 = 4 x 4 x 4

    = 4^3

So that;

4^2(3x - 6) = 4^3(x + 4)

Divide through by 4 to have;

2(3x - 6) = 3(x + 4)

6x - 12 = 3x + 12

collect like terms,

6x - 3x = 12 + 12

6x = 24

x = 24/6

  = 8

The answer to the work shown in the question is: x = 8

Options B and D is the correct answer.

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The inputs of the function are 1 and 2.

We have,

A function can have many-to-one but not one-to-many.

A

The graph shows a circle intercepting the x-axis at 5 and -5 and the y-axis also at 5 and -5.

This means,

If the center of the circle is (h, k).

The coordinates of the circle are:

(5, k), (-5, k), (h, 5), and (h, -5)

(h, 5) and (h, -5) indicate one-to-many.

This is not a function.

B.

If 30+6t=11t then the value of  t is: 6

This is a simple algebraic equation. To solve for t, we can start by isolating t on one side of the equation.

The equation is 30 + 6t = 11t

First we can subtract 11t from both sides:

30 + 6t - 11t = 11t - 11t

This gives:

30 - 5t = 0

Next, we can add 5t to both sides:

30 - 5t + 5t = 0 + 5t

This gives:

30 = 5t

Finally, we can divide both sides by 5:

30 / 5 = 5t / 5

This gives:

t = 6

Answer: Paula spent $2 for each song.

Step-by-step explanation: For this question, we have to find the unit rate that Paula paid per song. As we're already given the amount of songs downloaded and the total cost, all that we really have to do is divide!

Because we want to know the amount of money spent on one song, we divide the amount of money spent by the amount of songs purchased. This gives us 32/16 = 2.

Paula spent $2 (don't forget the units!) for each song. This is out unit rate. Hope this helps!

Answer: There are multiple ways that a function, g, could satisfy the given domain, range, and values of g(0) and g(-9). ✅

PLEASEEEE GIVE BRANLIEST

Step-by-step explanation:

There are multiple ways that a function, g, could satisfy the given domain, range, and values of g(0) and g(-9). One statement that could be true for g is:

g(x) = 2x + 8

This function has a domain of -20 ≤ x ≤ 5 and a range of -5 ≤ g(x) ≤ 45. It also satisfies the values of g(0) = -2 and g(-9) = 6.

It's important to note that this is only one possible function that satisfies the given information and there are many other functions that could also work such as:

g(x) = 3x -2

g(x) = -2x +10

g(x) = x+5

So the statement that could be true for g is that "There are multiple ways that a function, g, could satisfy the given domain, range, and values of g(0) and g(-9)."

The function f'(x) is decreasing on the interval (-√5, 0) and (0, √5)

A function is a mathematical equation that shows the relationship between two variables.

Givenj the function f'(x) = x⁵ - 5x³, to find the points at which the function is increasing, we find its critical points by equating it to zero.

So, f'(x) = x⁵ - 5x³

x⁵ - 5x³ = 0

x³(x² - 5) = 0

⇒ x³ = 0 and x² - 5 = 0

⇒ x = 0 and x² = 5

⇒ x = 0 and x = ±√5

To determine the points at which f'(x) is decreasing, we differentiate f'(x) with respect to x and substitute the values of x into it.

So, we have

f'(x) = x⁵ - 5x³

df'(x)/dx = d(x⁵ - 5x³)/dx

f"(x) = 5x⁴ - 15x²

So, f'(x) is decreasing when f"(x) > 0.

So, substituting x = 0 into the equation, we have that

f"(x) = 5x⁴ - 15x²

f"(x) = 0⁴ - 15(0)²

= 0 - 0

= 0

Since f"(x) = 0. This is a point of inflection

Substituting x = √5 into the equation, we have that

f"(x) = 5x⁴ - 15x²

f"(x) = 5(√5)⁴ - 15(√5)²

= 5 (25) - 15 (5)

= 125 - 75

= 50

Since f"(x) = 50 > 0, f'(x) is decreasing

Substituting x = -√5 into the equation, we have that

f"(x) = 5x⁴ - 15x²

f"(x) = 5(-√5)⁴ - 15(-√5)²

= 5 (25) - 15 (5)

= 125 - 75

= 50

Since f"(x) = 50 > 0, f'(x) is decreasing

So, f'(x) is decreasing on the interval (-√5, 0) and (0, √5)

a. The y-intercept of the graph is 35,000, which represents the original purchase price of the car. Therefore, the car was purchased for $35,000.

b. We can see from the graph that the car's value becomes 0 after 9 years. Therefore, the car totally depreciates after 9 years.

c. The equation of a straight line can be written as y = mx + b, where m is the slope and b is the y-intercept. The slope of the graph is the rate of depreciation, which is -4000. The y-intercept is the original price of the car, 35000.

So the equation of the straight line depreciation graph is: y = -4000x + 35000

This equation represents the value of the car, where y is the value of the car (in dollars) x is the number of years since the car was purchased and -4000 is the rate of depreciation and 35000 is the original price of the car.

Answer:

the having of the record is that

To the nearest whole percent, the percentage Yvette paid over the price of the sandwiches is 27%.

The percentage represents a proportion of a whole value.

The percentage is determined as the quotient of the difference (increase or decrease) and the initial value, multiplied by 100.

The purchase price of restaurant sandwiches = $22

Sales tax = 8.5%

= $1.87 ($22 x 8.5%)

Additional tip for delivery = 18%

= $3.96 ($22 x 18%)

Total bill = $27.83 ($22 + $1.87 + $3.96)

Difference between the total bill and the purchase price = $5.83 ($27.83 - $22)

Percent difference = 26.5% ($5.83/$22 x 100)

= 27%

Thus, Yvette paid 27% above the price of the sandwiches in form of sales tax and tips.

A parabola is a plane curve which is mirror-symmetrical and is approximately U-shaped. It fits several superficially different mathematical descriptions, which can all be proved to define exactly the same curves.

Given that, The cross-section of the reflector in a flashlight is a parabola, the light bulb is located at the focus of the cross-section, 2.5 cm in front of the vertex.
