Because if you are multiplying or dividing, you can regroup numbers to make it easy so exg
80 times 45 might look scary but it is really 2 times 2 times 2 times 2 times 3 times 3 times 5 times 5
regroup to make
(2 times 5) times (2 times 5) times (2 times 2 times 3 times 3)=10 times 10 times (6 times 6)=10 times 10 times 36=3600

dividing
188/132
188=2 times 2 times 47
44=2 times 2 times 3 times 11
so it becomes (2 times 2)/(2 times 2) times (47/(3 times 11))=1 times 47/33=47/33

Simplified radical form of 4800 feet how many seconds was the diver in a free fall? Using functions (t)=16t^2 models the distanc
amm1812

Answer:

The diver will be in free fall for 10\sqrt{3} seconds.

Step-by-step explanation:

The distance in feet, that an object falls in t seconds is given by the function h(t) = 16t^{2}.

Now, given that the height is 4800 feet and we have to calculate the number of seconds the diver was in a free fall.

Therefore, 4800 = 16t^{2}

⇒ t^{2} = \frac{4800}{16} = 300

⇒ t = \sqrt{300} = \sqrt{100 \times 3} = 10\sqrt{3} seconds.

Therefore, the diver will be in free fall for 10\sqrt{3} seconds. (Answer)

Let p=x^2+6
stepan [7]
That's a bit of a nasty. Where ever you see (x^2 + 6) you put in p.
p^2  - 21 = 4(x^2 + 6)
p^2 - 21 = 4p
p^2 - 4p - 21 = 0

Pie

Answer:

(f-g)(4) = 10

Step-by-step explanation:

(f-g)(x) = f(x) - g(x)

= 1/2 x^2 - 1/4 x + 4 - 1/2 x + 1

= 1/2 x^2 - 1/4 x - 1/2 x + 4 + 1

= 1/2 x^2 - 3/4 x + 5

(f-g)(4)

= 1/2 (4)^2 - 3/4 (4) + 5

= 1/2 * 16 - 3 + 5

= 8 - 3 + 5

= 5 + 5

= 10
