Answer:

Step-by-step explanation:

If by t1/2 you mean \sqrt{t} then since a is in m/s^2,

A is m/s^2

B is m/s^{3/2}

A certain factory produces and sells 8000 cars per month, making a monthly net profit of P dollars. They sell
vredina [299]

Answer:

p= 8000n-8000c

Step-by-step explanation:

8000

p= n - c

or

p= 8000n-8000c

Esentially you need to subtract n, the amount they sell each car for by c, the amount it costs to produce a car, <em>(which should be less because the company has to make money)</em><em> </em>this would give you the total they make a month, P.

Because the amount of cars is constant, 8000, you can always multiply the cost of the car and how much its sold for by 8000. Otherwise, you would have another variable like k, which would be how many cars sold

Eight expressions are given below. Determine whether each expression is equivalent to 5^10 or not equivalent to 5^10.
KengaRu [80]

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete, as the 8 expressions are not given.

The general explanation is as follows

As complex as an expression may seem, you have to simplify each expression until it cannot be further simplified.

Then you categorize each result, depending on if it equals 5^{10} or not

Take for instance:

5^5 * 5^5

Using law of indices:

5^5 * 5^5 = 5^{5+5

5^5 * 5^5 = 5^{10 ---- equivalent

\frac{5^5 + 5^5}{2 * 5^{-5}}

Factorize the numerator

\frac{5^5 + 5^5}{2 * 5^{-5}} = \frac{5^5(1  + 1)}{2 * 5^{-5}}

\frac{5^5 + 5^5}{2 * 5^{-5}} = \frac{5^5 * 2}{2 * 5^{-5}}

Cancel out 2

\frac{5^5 + 5^5}{2 * 5^{-5}} = \frac{5^5}{5^{-5}}

Apply law of indices

\frac{5^5 + 5^5}{2 * 5^{-5}} = 5^{5--5}

\frac{5^5 + 5^5}{2 * 5^{-5}} = 5^{5+5}

\frac{5^5 + 5^5}{2 * 5^{-5}} = 5^{10 ---equivalent

125 * 78125

Express as exponent

125 * 78125  = 5^3 * 5^7

Apply law of indices

125 * 78125  = 5^{3+7

125 * 78125  = 5^{10 ---- equivalent

5^3 + 5^7

Solve exponents

5^3 + 5^7 = 125 + 78125

5^3 + 5^7 = 78250 ---- not equivalent

Use the graph to evaluate the function for the given input value.
Angelina_Jolie [31]

The  evaluation of the function for the given f(-1), f(1)   input value is  mathematically given as

  • f(-1) = -8
  • f(1) = -12

<h3>What is the evaluation of the function for the given f(-1), f(1)   input value?</h3>

In the field of mathematics, an assignment of one element from set Y to each and every element in set X is the definition of a function. This particular set, X, is referred to as the function's domain, and this particular set, Y, is referred to as the function's codomain. Historically, functions have been seen as an idealization of the way in which one variable relies on another variable.

-1 and 1 are both considered to be input when evaluating the function f, which is represented by the graph.

Since the inputs are on the x-axis, the graph demonstrates that the value of the function f at -1 is about -8 when x equals -1.

When x equals 1, the value of the function f is close to -12.

What is 55 1/5 - 32 3/4
garik1379 [7]

Answer:

449/20 or 22 9/20

Step-by-step explanation:

Change them to mixed numbers.

55 x 5 = 275 + 1 = 276

32 x 4 = 128 + 3 = 131

Then, convert them to a common denominator.

276 x 4 = 1104

131 x 5 = 655

1104 - 655 = 449

449/20
