There are
ways of building a subset of
elements from
, so the total number of subsets you can build is

Recalling the binomial theorem, the above sum is equal to

as required.
7/8 = 14*(1/16)
Maybe you're expecting
7/8 = 7*(1/8)
Answer:
See below
Step-by-step explanation:
Q7
- g(s) = 2s + 3,
- g(-2) = 2(-2) + 3 = -4 + 3 = -1
Q8
- h(x) = x² - x + 7
- h(4) = 4² - 4 + 7 = 16 + 3 = 19
Q9
Basic channels = $32.50, each premium channel = $4.95
a) <u>Equation:</u>
b) <u>Table:</u>
- p = 0 ⇒ c = 32.50
- p = 1 ⇒ c = 4.95 + 32.50 = 37.45
- p = 2 ⇒ c = 2*4.95 + 32.50 = 42.40
- p = 3 ⇒ c = 3*4.95 + 32.50 = 47.35
- p = 4 ⇒ c = 4*4.95 + 32.50 = 52.30

Answer:
80 units
Step-by-step explanation:
When a figure is dilated by 2, its side measurements are halved. The figure you're seeing shows the quadrilateral <em>after </em>dilation (we can tell by the apostrophes); if U'R' is 40, UR will have to be 80.
Answer: 169.2cm
Step-by-step explanation:
From the question, we are informed that three equal-sized cardboard boxes are stacked on top of each other and that each box is 56.4 cm in height.
To get the combined height of the 3 stacked boxes, we multiply 56.4cm by 3. This will be:
= 56.4cm × 3
= 169.2cm
