Answer:

See below

Step-by-step explanation:

(ii) \\  \\  {x}^{3}  + 2 {x}^{2}  + 5x + 10 \\  \\  =  {x}^{2} (x + 2) + 5(x + 2) \\  \\  = (x + 2)( {x}^{2}  + 5) \\  \\ (iii) \\  {a}^{3}  -  {a}^{2}  {b}^{2}  - ab +  {b}^{3}  \\  \\  =  {a}^{2} (a -  {b}^{2} ) - b(a -  {b}^{2} ) \\  \\  = (a -  {b}^{2} )( {a}^{2}  - b)

The graph shows the function f(x)=3^x
tangare [24]
The answer is D.
You have to make the whole numbers equal to then solve for the exponents:
F(x) means y, therefore, y is 9.
9 = 3^x.
3^2 is the same as 9.
Then, 3^2 = 3^x.
Then solve for the exponents,
2 = x
Therefore your answer is 2.

The formula for centripetal acceleration, a, is given below, where v is the velocity of the object and r is the object's distanc
julsineya [31]

Answer:

Step-by-step explanation:

For this case we have the following equation:

a = v ^ 2 / r

From here, we must clear the value of speed.

We have then:

v ^ 2 = a * r

v = root (a * r)

Answer:

the formula for the velocity is:

v = root (a * r)

My brother needs help and I have load of hw plz help
Ilya [14]
The ratio indicates that there are 8 dolls for every 7 teddy bears. That means that if there is 16 dolls, then there is 14 teddy bears. And that if there is 24 dolls, then there is 21 teddy bears. You could continue this pattern, or you could divide and multiply. If you have 160 dolls, then do 160/8 to simplify the ratio. You get 20. So if there is (8x20) dolls, then there is (7x20) teddy bears. 7x20 is 140, so there are 140 teddy bears.
