Evaluate the expression 6^2 + x-x^2 for x=3

Mathematics
1 answer:
Paha777 [63]3 years ago
8 0

Answer:

30

Step-by-step explanation:

Given the following mathematical expression;

6² + x - x²

When x = 3

Thus, we would substitute the value of "x" into the expression;

36 + 3 - (3)²

Applying BODMAS (Bracket of Division, Multiplication, Addition and Subtraction).

36 + 3 - 9

39 - 9

30.

Answer:

$4785.68

Step-by-step explanation:

Original amount: <u>$</u><u>4</u><u>2</u><u>3</u><u>0</u>

Interest for 1 year: <u>4</u><u>.</u><u>2</u><u>%</u>

<em>First year;</em>

4230 + (4230 \times  \frac{4.2}{100})  \\  = 4230 + 177.66 \\  = 4407.66

<em>S</em><em>e</em><em>c</em><em>o</em><em>n</em><em>d</em><em> </em><em>y</em><em>e</em><em>a</em><em>r</em><em>;</em>

4407.66 + (4407.66 \times  \frac{4.2}{100} ) \\  = 4407.66 + 185.12172 \\  = 4592.78172

<em>T</em><em>h</em><em>i</em><em>r</em><em>d</em><em> </em><em>y</em><em>e</em><em>a</em><em>r</em><em> </em><em>(</em><em>t</em><em>o</em><em>t</em><em>a</em><em>l</em><em> </em><em>b</em><em>a</em><em>l</em><em>a</em><em>n</em><em>c</em><em>e</em><em> </em><em>a</em><em>f</em><em>t</em><em>e</em><em>r</em><em> </em><em>3</em><em> </em><em>y</em><em>e</em><em>a</em><em>r</em><em>s</em><em>)</em><em>;</em>

4592.78172 + (4592.78172 \times  \frac{4.2}{100} ) \\  = 4592.78172 + 192.89683224 \\  =4785.67855224

Round the number;

<em><u>$4785.68</u></em>

WILL MARK BRAINLIEST!!! PLZ HELP! The following graph describes function 1, and the equation below it describes function 2. Dete
Assoli18 [71]

Answer:

C

Step-by-step explanation:

The maximum/minimum values is simply the y-value of the vertex. Since both of the functions have a negative leading coefficient, they will both have maximum values.

For Function 1, we can see that the vertex is at (4,1). Thus, it's maximum value is at y=1.

For Function 2, we need to work out the vertex. To do this we can use:

x=\frac{-b}{2a} ,y=f(-b/2a)

To find the vertex.

Function 2 is defined by:

f(x)=-x^2+4x+1

Therefore:

a=-1, b=4, c=1

x=-(4)/2(-1)=-4/-2=2\\f(2)=-(2)^2+4(2)+1\\=-4+8+1\\=4+1=5

Thus, the vertex of Function 2 is at (2,5). Therefore, the maximum value of Function 2 is y=5.

5 is greater than 1, so the maximum value of Function 2 is greater.

The answer is choice C.
