Answer:

x=67

Step-by-step explanation:

The correct statement is,

(B) f(x) has a greater maximum value than g(x).

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given that;

Function f (x) is,

f (x) = - 8x² + 7

Now, First, we determine the maximum point of f(x).

f(x) is at maximum at the point of symmetry, i.e. where x = - b/a

Here, a = -8, b = 0

Hence, x = - 0 / - 8 = 0

So, We get;

f (0) = - 8 x 0 + 7 = 7

Thus,

The maximum point of f(x) is (0,7)

And, The maximum point of g(x) is (2,6)

Therefore, f(x) has a greater maximum value than g(x).

Hence3, The correct option is B.

Answer and Step-by-step explanation:

First, we find the area of one area of a face on the cube.

6.5 × 6.5 = 42.25

Now, we times 42.25 by 6, since there are 6 faces on a cube.

42.65 × 6 = 253.5

The answer is 253.5

Answer:

Multiply both sides by -2 and reverse the inequality symbol.

Step-by-step explanation:

To isolate w, multiply both sides by the reverse of -1/2 (because -1/2*2=1 ), which is -2

When multiplying or dividing by negatives, you must reverse the inequality symbol as well.

To isolate the variable,  you multiply both sides by -2 and reverse the inequality symbol.

Isolation of variables means making the variable the subject of the formula from the given expression.

Given the inequality expression -1/2 w  < 12

To make w the subject of the formula, we will have to multiply both sides by -2 to have;

-1/2 w * -2 >  12 * -2
w > -24

Hence to isolate the variable,  you multiply both sides by -2 and reverse the inequality symbol.

Answer:

The number of skateboards of each color is 11 and 4

Step-by-step explanation:

Let x represent blue skateboards and

y represent red skateboards.

From the question, the total number of skateboards is 15, that is,

x + y = 15 ...... (1)

and their product is 44, that is,

xy = 44 ...... (2)

From equation (1),

x + y = 15

We can write that

x = 15 - y ...... (3)

Substitute this into equation (2)

xy = 44

(15-y)y = 44

15y -y² = 44

Then,

y² - 15y + 44 = 0

Solve quadratically

y² -4y -11y + 44 = 0

y(y-4) -11(y-4) = 0

(y-11)(y-4) = 0

y-11 = 0 OR y-4 = 0

y = 11 OR y = 4

Put the values of y into equation (3) for x

x = 15 - y

When y = 11

x = 15 - 11

x = 4

and when y = 4

x = 15 -4

x = 11

(4,11) and (11,4)

It is either 4 blue and 11 red skateboards OR 11 blue and 4 red skateboards.

Hence, the number of skateboards of each color is 11 and 4.

Answer:

The length of the diagonal is x√10

Step-by-step explanation:

Here, we want to find the length of the diagonal

The diagonal will represent the hypotenuse of a triangle formed with the width and length of the triangle being the measure of the other sides

Mathematically, we then apply Pythagoras’ theorem to get this

we have this as that the square of the diagonal equals the sum of the squares of the two other sides

d^2 = x^2 + (3x)^2

d^2 = x^2 + 9x^2

[tex]f(d) = 15 + 3d[/tex]

Step-by-step explanation:

Given

[tex]a = 15[/tex] --- day 1

[tex]Rate = 3[/tex] -- i.e. triples daily

Required

Determine the function f(d)

The number of customers on a particular day is:

Customers = Day 1 + Rate * Number of days

Represent as a function:

[tex]f(d) = a + Rate* d[/tex]

Where d is the number of days.

So, we have:

[tex]f(d) = 15 + 3* d[/tex]

[tex]f(d) = 15 + 3d[/tex]
