Answer:

a. 12 cups - 2 * n cups b. 2 * (6-n) cups

Step-by-step explanation:

a.

we start with 12 cups of flour

we subtract 2 cups of flour for each baking cycle

thus, cups of flour = 12 cups - 2 cups for each cycle

2 cups for each cycle = 2 cups * number of cycles = 2 cups * n

cups of flour = 12 cups - 2 * n cups

b.

note that 12 is a multiple of 2 -- 2 * 6 = 12

thus, 12 cups = 2* 6 cups

cups of flour = 12 cups - 2 * n cups = 2 * 6 cups - 2 * n cups

factor out the 2

cups of flour = 2 * (6-n) cups

Using function concepts, it is found that the correct option is given by:

a.Yes, this graph represents a polynomial. There are two turning points and the least degree possible is three.

Supposing a polynomial with n turning points, the least possible degree is of n + 1.

In this problem, the polynomial has 2 turning points, hence the least possible degree is of 3 and option a is correct.

Perimeter of ΔA'B'C' is 52 cm.

The perimeter of ΔABC is =13 cm

Length of OB = 5 cm

Length of OB' = 15 + 5 = 20 cm

The Dilation factor can be found out b

ΔOCB and ΔOC'B' are similar as BC|| B'C'

From triangles ΔOCB & ΔOC'B' the dilation factor can be found out

by the formula below

[tex]\frac{BC}{B'C'} =\frac{5}{20}[/tex]

B'C'= 4BC

so the dilation factor = 4

hence the new perimeter of the triangle = 13  4 = 52 cm

Answer: 4

Step-by-step explanation:

The given function :

The average rate of change in a function g(x) from x=a to x=b is given by :-

Then, the average rate of change of the given function from x = 1 to x = 3 will be :-

x = 1 to x = 3 is 4

Answer:

x = 15

Step-by-step explanation:

angle FoH = 360° - 90° - 90° - angle G

= 180° - 75°

= 105°

17x° = 360° - angle FoH

17x° = 360° - 105°

17x° = 255°

x = 255 ÷ 17

x = 15

Answer:

x = 4

Step-by-step explanation:

We know that,

A parallelogram is a quadrilateral whose opposite sides are parallel.

Then the value of x will be,

→ 5x - 16 = 4

→ 5x = 4 + 16

→ 5x = 20

→ x = 20/5

→ [ x = 4 ]

Verification of the value of x,

→ 5x - 16 = 4

→ 5(4) - 16 = 4

→ 20 - 16 = 4

→ 4 = 4

→ [ LHS = RHS ]

Hence, the value of x is 4.

Answer:

Step-by-step explanation:

Not A as cost is always increasing with x.

Yes B as is x squared relationship

Yes C as 15*9 = 135

No D as it is a squared relationship so much more than double

Not E as the the cost increases by a different amount for each increase in x.

The possible dimension of the new box is 16 x 10 x 4 inches

Thomas buys a box that is 8 by 10 by 4 inches. Thomas wants to double the volume of his original box. what could be the new dimensions of the box? recorded in length, width, height.

The dimension of the box is given as:

Dimension: 8 by 10 by 4

So, the volume of the box is:

Volume = 8 * 10 * 4

When the volume is doubled, we have:

Volume = 2 * 8 * 10 * 4

Evaluate the product

Volume = 16 * 10 * 4

This means that the possible dimension of the new box is 16 x 10 x 4 inches
