Please give me the correct answer

Less than 20 times faster

Step-by-step explanation:

Ok so first lets simplify this expression.

3 * 10^3

Since its multiplying by 10, you add zeros on. The exponent determines where the zeros go, in front of behind the three. Since its positive, the zeros will go behind because the number will be getting larger.

So 3 * 10^3 = 3 * 1000

3000

Same with 7 * 10^3

7 add 3 zeros to the end because of the exponent on the 10.

7000

[Please note: This only works when its 10]

Now you subtract the hawks speed from the aircraft to see how much faster the jet goes.

7000-3000

4000

That leaves you with 4000 km/h

That's not an answer choice so lets do some more math.

An easy way to get this is to times our result by 20 because that's what the answer choices are.

4000*20

80000

You can clearly see this is greater than 7000 so we can determine that the jet is less than 20 times faster.

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
