Answer:

3^-2=1/9

3^0=1

3^1=3

3^2=9

Answer:

3^-2 = 1/9

3^0 = 1

3^1 = 3

3^2 = 9

Answer:

(9-57i)

Step-by-step explanation:

We need to find the product of the given complex number i.e.

(3-9i)(6-i)

It can be solved as follows :

(3-9i)(6-i) = 3(6) +3(-i) +(-9i)(6) + 9i(i)

= 18-3i-54i+9i²

We know that, i² = -1

So,

= 18-3i-54i+9(-1)

= 18-57i-9

= 9-57i

So, the product of the given complex number is (9-57i).

Step-by-step explanation:

Answer:

The equation for the speed of the train is: 162 = 3x

I think the speed of the train is 54 miles per hour

Step-by-step explanation:

We know that:

y = distance in miles

x = speed of train (miles/hour)

t = time traveled from the departing station (hours)

The equation: y = xt is given, we can therefore substitute the give values:

y = xt or tx

162 = 3x (This would be the equation)

Now we can find x by diving 3 on both sides of "="

162/3 = x

54 = x (This would be the speed of train)

Hope this helps!

Answer:

5.44444442889 or 5 [tex]\frac{4}{9}[/tex]

Step-by-step explanation:

Just multiply the 2 numbers together

Answer:

[tex]2\frac{1}{3}^{2}[/tex] or 49/9 inches squared

Step-by-step explanation:

you have a square if those lengths are correct, and the formula for the area of a square is Bh=A B=base length (side on bottom), h=height (vertical side), and A=area, so 2 1/3 * 2 1/3 or 2 1/3^2

if that doesnt make sense, message me and i will try to help you more

Answer:

C) $160,500

Step-by-step explanation:

52,500×15=787,500

63,200×15=948,000

948,000- 787,500= 160,500

Answer:

the diameter of Britain flag is given = 28mm

so the radius = 14mm

perimeter of the flag occupied = 2πr = (2×22/7×14) mm

= 88mm

area of the flag= πr^2 = (22/7 × 196) mm^2 = 616 mm^2

Answer:

48pq².

Step-by-step explanation:

(4pq+3q)² - (4pq - 3q)²​

This is the difference of 2 squares so we can use the identity

a^2 - b^2 = (a - b)(a + b):

(4pq+3q)² - (4pq - 3q)²​

= (4pq + 3q - (4pq - 3q)(4pq + 3q + (4pq - 3q)

= (4pq + 3q - 4pq + 3q)(4pq + 3q + 4pq - 3q)

= 6q * 8pq

= 48pq².

Answer:

48pq²

Step-by-step explanation:

As we know,

(a + b)² = a² + 2ab + b²

and

(a – b)² = a² – 2ab + b²

So,

(4pq+3q)² - (4pq - 3q)²​

= [(4pq)² + 2 X 4pq² X 3q + (3q)²] – [(4pq)² -  2 X 4pq² X 3q + (3q)²]

= (16p²q² + 24pq²+ 9q²) – (16p²q² – 24pq²+ 9q²)

= 16p²q²+ 24pq²+ 9q² – 16p²q²+ 24pq² – 9q²

= 24pq² + 24pq²

= 48pq²

Answer:

5 apples cost = 150 /-

Step-by-step explanation:

Two apples cost = 60 /-

Then 1 apple cost = 60 ÷ 2

= 30

∴ 1 apple cost = 30 /-

Then 5 apples cost = 30 × 5

= 150

∴ 5 apples cost = 150 /-
