(11-8)x3+7+27-3<br> (18÷3)+6+(14-8)x5<br> (11-7)x6+4+32-4
horsena [70]

The results of the arithmetic evaluations as given in the task content are; 40,42 and 62.

<h3>What are the results of the arithmetic evaluations?</h3>

The arithmetic operations above can be evaluated and simplified as follows;

(11-8)x3+7+27-3 = (3×3)+7+27-3 = 40.

(18÷3)+6+(14-8)x5 = (6)+6+(6)x5 = 42.

(11-7)x6+4+32-4 = (5×6) +4 +32-4 = 62.

Quadratic functions. Linear, exponential, or a new kind of function? E and f?
vovangra [49]

e.

5^0 = 1; 5^1 = 5; 5^2 = 25; 5^(-1) = 1/5; 5^(-2) = 1/25

This is an exponential function since the exponent is a variable.

Function: f(x) = 5^x

Recursive: a_n = 5a_{n-1}

f.

Look at f(x) = x^2 for x = -2, -1, 0, 1, 2

f(-2) = 4

f(-1) = 1

f(0) = 0

f(1) = 1

f(2) = 2

Now look at the y-values in the table. They are the same we have here added to 5.

Your function is a quadratic function.

f(x) = x^2 + 5

The LCD for the fractions 1/3, 3/4, 5/32, and 8/9 is
tresset_1 [31]
What is the smallest number divisible by 3, 4, 32 and 9?
You might want to try factoring these denominators and writing them in their factored form:

3, 2^2, 2^5, 3^2

Your LCD must include the following factors:  3^2 and 2^5, or 9 and 32.  Multiplying these together results in the correct LCD 9*32=288.

Check:  Is 288 divisible by 3?  Yes.  The quotient is 96.
Is 288 divisible by 4?  Yes.  Is 288 divisible by 32?  Yes.  Is 288 divisible by 9?  Yes.
