Write an expression without exponent that is equivalent to 2 to 3rd power nd 4 to the 3rd power

attashe74 [19]

Answer:

2 to the 3rd power,

2*2*2

4 to the 3rd power,

4*4*4

Step-by-step explanation:

The "3rd power" means how many times the number given to it would be multiplied. Aka, 2 to the 4th power would mean 2 times 2 times 2 times 2, (2 four times).

I need the answer plz

Answer:

I can't solve and show it but only tell a method to do it!

So find the zero of the given factor:

i.e.

$(x + 1) \\ x = - 1$

Now put its value (-1) in the polynomial

${x}^{3} - 13 {x}^{2} + 32x - 20$

Now if the answer comes zero it is a factor.

You'll get your answer!

Last week at a festival, a man sold 4 times as many tie-dyed T-shirts as silk screened shirts. He sold 180 shirts altogether. Ho

lyudmila [28]

Let the number of tie-dyed T-shirts = x

The man sold 4 times as many tie-dyed T-shirts as silk-screened shirts.

So, the number of silk-screened shirts = 4x

He sold 180 shirts altogether

So,

$\begin{gathered} x+4x=180 \\ 5x=180 \\ \\ x=\frac{180}{5}=36 \end{gathered}$

So, the number of tie-dyed shirts = 36

The range of the function y = 2cos x is -2 ≤ y ≤ 2.

Vadim26 [7]

Answer:

The range of the function y = 2cos x is -2 <y < 2 .

Step-by-step explanation:

We know that cos (0) = 1 and cos (π) = - 1 are the two extreme values which cos x assume when x ∈ R and it is also that cos (x) is a continuous periodic function with period 2π when x ∈ R ,

since ,

cos (x + 2π) = cos x

So, the range of the function y = 2cos x is -2 <y < 2 .
