Answer:

see explanation

Step-by-step explanation:

(a)

Record the number of sticks and look for a pattern

1 → 6 sticks

2 → 10 sticks

3 → 14 sticks

There is a difference of + 4 between each pattern, thus add 4 to the previous pattern , that is

4 → 14 + 4 = 18

5 → 18 + 4 = 22

6 → 22 + 4 = 26

That is there are 26 sticks in pattern number 6

---------------------------------------------------------------------------

(b)

Multiplying the pattern number (n) by the difference 4 gives

4 × 1 = 4 ← require to + 2 for 6

4 × 2 = 8 ← require to + 2 for 10

4 × 3 = 12 ← require to + 2 for 14

Thus pattern number n would have

sticks = 4n + 2

Answer:

9800 cm^2

Step-by-step explanation:

The area of a square is just the length of one of the sides squared. In the first image it's given that one of the sides is 70 cm and the shape is also a square pyramid so the base is going to be a square. So the area the base is (70 cm) ^ 2 = 4,900 cm^2. The area of a triangle is 1/2 bh. The base is given in the first image which is 70 cm and the height is also given which is 140 cm. This gives you the equation 0.5 * 140 cm * 70 cm = 4900 cm^2. Adding these two values gives you 9800 cm^2

Each side of a square is increasing at a rate of 5 cm/s. At what rate is the area of the square increasing when the area of the

icang [17]

Answer:

Step-by-step explanation:

Area of a square with side of length L is expressed as A = L². The rate at which the area is increasing will be expressed as dA/dt.

dA/dt = dA/dL * dL/dt where

dL/dt is the rate at which each side of the square is increasing.

Since dA/dL = 2L, dA/dt = 2L dL/dt

Given dL/dt = 5cm/s and the Area of the square = 49 cm²

49 = L²

L = √49

L = 7cm

dA/dt = 2(7) * 5

dA/dt = 14*5

dA/dt = 70cm/s

The rate at which the area of the square is increasing is 70cm/s
