Answer:

\(\mathrm{V=\sqrt[3]{36}}\)

Step-by-step explanation:

Determine if 36 is a cube root

(a-b)•(a^2+ab+b^2) =

           a^3+a^2b+ab^2-ba^2-b^2a-b^3 =

           a^3+(a^2b-ba^2)+(ab^2-b^2a)-b^3 =

           a^3+0+0-b^3 =

           a^3-b^3

→ Using this checker, we can see that 36 is not a cube root because it cannot be factored as the difference between two perfect cubes.

Solve

v^3 - 36 = 0

v^3 = 36

v = ∛36

You have the following information:

- Alonzo drove 380 miles using 14 gallons of gas

In order to determine how many gallons of gas would Alonzo need to drive 418 miles, you consider that each 380 miles are equivalent to 14 gallons of gas.

Then, you can use the following rule of three:

380/14 = 418/x

where x is the unknown amount of gallons of gas Alonzo needs. The rate must be equal because Alonzo drives with constant speed.

Then, you solve the previous equation for x, just as follow:

380/14 = 418/x multiply both sides by x

(380/14)x = 418 multiply by 14 and divide between 380 both sides

x = 418(14/380) simplify

x = 15.4

Hence, Alonzo would need 15.4 gallons of gas to drive 418 miles

The piecewise function graphed below is given as follows:

A piecewise function is a function that has different definitions, depending on the input.

For x between -4 and -2, inclusive, the function is constant at 3, hence the definition is:

\(f(x) = 3, -4 \leq x \leq -2\)

For x greater than -2 until 3, the function is a line with slope 1 and y-intercept 2, hence the definiton is:

\(f(x) = x + 2, -2 < x \leq 3\)

For x greater than 3 until 5, the function is constant at -1, hence the definition is:

\(f(x) = -1, 3 < x \leq 5\)

Answer:

7*36=21*x

252=21x

x=12

Hope it helps!

Answer:

12

Step-by-step explanation:

Let x be the unknown number.

Method 1

\(\implies \sf 7 \times 36 = 21 \times x\)

\(\implies \sf 252 = 21x\)

\(\implies \sf \dfrac{252}{21} = \dfrac{21x}{21}\)

\(\implies \sf 12=x\)

\(\implies \sf x=12\)

Method 2 (using mental arithmetic)

\(\implies \sf 7 \times 36 = 21 \times x\)

As 7 and 21 are both multiples of 7, divide both sides by 7:

\(\implies \sf 36=3x\)

Divide both sides by 3:

\(\implies \sf 12=x\)

\(\implies \sf x=12\)

Mixed Number: 7 And 1/10

Improper Fraction: 71/10

Please give me Brainliest if I'm right ! :)

Answer:

Mixed Number: 7 1/10

Improper Fraction: 71/10

Step-by-step explanation:

A Mixed Number is a Number with a fraction as part of it so 7 is a whole number, so this is the "number" part. .1 isnt a whole number, so you find out what the simplified form of .1 is, and you get 1/10. Put them together and you get 7 1/10. An improper fraction is where the number becomes only a fraction, no whole numbers allowed! you can find out 1 = 10/10 so this means 7 = 70/10. Add the .1 (1/10) to this and you get 71/10.

Monique needs 30 fluid ounces of orange juice to keep the ratio same.

Ratio is the quantity of certain type of amount out of the total amount of all types is quantities.

According to the given question
The fruit punch is made up of 32 fluid ounces of pineapple juice and 48 fluid ounces of orange juice.

∴ The total Mixed juice is

(32 + 48) = 80 fluid ounces of mixed juice.

The ratio of pineapple juice juice to the orange juice is

32:48

= 2x:3x

Now Monique has 20 fluid ounces of pineapple juice

∴2x = 20

    x = 10

So, to keep the ratio of pineapple juice to the orange juice same she needs 3x or 30 fluid ounces of orange juice.

6x+2-1x+5=42

Step-by-step explanation:

Answer:

6x+2-x-5=42

Step-by-step explanation:

If f (x) < g(x) for all real 1; The expression that must be true is I f'(x)sg'(x) for all real x II. f'(x)≤g'(x) for all real x III. f(x)dx ≤ [8(x)dx is option D. I and II only

I. f(x) and g(x) have continuous first and second derivatives everywhere, so by the mean value theorem, there exists a point c in the interval (a, b) such that f'(c) = (f(b) - f(a)) / (b - a) and g'(c) = (g(b) - g(a)) / (b - a). Since f(x) < g(x) for all x, we have f(b) - f(a) < g(b) - g(a), so f'(c) < g'(c), and thus, f'(x) < g'(x) for all x.

II. f(x) and g(x) have continuous first and second derivatives everywhere, so by the mean value theorem, there exists a point c in the interval (a, b) such that f''(c) = (f'(b) - f'(a)) / (b - a) and g''(c) = (g'(b) - g'(a)) / (b - a). Since f'(x) < g'(x) for all x, we have f'(b) - f'(a) < g'(b) - g'(a), so f''(c) < g''(c), and thus, f''(x) < g''(x) for all x.

III. This statement is not necessarily true. The definite integral of f(x)dx is equal to the area between the curve and the x-axis, and the definite integral of g(x)dx is equal to the area between the curve and the x-axis. The definite integral of a function does not depend on the value of the function at each point, but on the overall shape of the curve, so it is not guaranteed that f(x)dx ≤ g(x)dx just because f(x) < g(x) for all x.

The running times of the given expressions can be expressed in big O notation as follows:

43n + 52n^2 + 14n: This expression has the highest degree term as n^2. Therefore, the running time can be expressed as O(n^2), indicating that the running time grows quadratically with the input size n.

54n: This expression has a linear relationship with the input size n. Hence, the running time can be expressed as O(n), indicating that the running time grows linearly with the input size.

66n^2 + 61n: Similar to the first expression, this expression has the highest degree term as n^2. Therefore, the running time can be expressed as O(n^2), indicating a quadratic growth rate.

log(n) + 88n + 31n: The logarithmic term log(n) has a slower growth rate compared to the linear terms 88n and 31n. Hence, the overall running time can be expressed as O(n), indicating a linear growth rate.

(9n*(5n + 7)(8n+9)) / 50: This expression involves multiple terms and factors. However, the highest degree term is n^3. Therefore, the running time can be expressed as O(n^3), indicating a cubic growth rate.

29: This expression represents a constant value. Regardless of the input size, the running time remains constant. Hence, it can be expressed as O(1).

46n log(n) + 52n: The presence of the logarithmic term log(n) indicates a slower growth rate compared to the n term. Therefore, the running time can be expressed as O(n log(n)), indicating a growth rate between linear and quadratic.

11n + 44n^2 + 33n: This expression has the highest degree term as n^2. Therefore, the running time can be expressed as O(n^2), indicating a quadratic growth rate.

In summary, the running times of the given expressions can be summarized as follows: two expressions have a quadratic growth rate (O(n^2)), two have a linear growth rate (O(n)), one has a cubic growth rate (O(n^3)), one is constant (O(1)), and two have a growth rate between linear and quadratic (O(n log(n))).

Answer:

$13,450

Step-by-step explanation:

The fixed costs of production, are the costs incurred that are independent from the production volume, that is, regardless of how many spinners the company produces, those costs will remain the same. If 'x' is the number of spinners produced, interpreting the cost function, we can see that it costs $1.28 to produce each spinner and that there is a cost that does not rely on production of $13,450. Therefore, the fixed cost of production is $13,450.
