Average speed = (1/2) (beginning speed + ending speed)
= (1/2) ( 13 m/s + 30 m/s )
= (1/2) ( 43 m/s )
= 21.5 m/s
Answer:
b
Step-by-step explanation:
The volume is B. 1296 because 16 times 9=144.144 times 9=1296.
The factored form of the equation 9x⁴y - 6x³y² + 3x²y³ is 3x²y(3x²-2xy+y²).
<h3>What is factored form?</h3>
The product of a constant and two linear expressions in factored form. The roots of the function are the parameters and the x-intercepts of the graph. Often Factoring is referred to as the process of converting a quadratic function to factored form.
We need to write the given expression
in the factored form, therefore, we will take the common terms out of the given expression,
1. Taking 3 as the common term, we will get,

2. Taking x² as the common term

3. Taking y as the common term,

Hence, the factored form of the equation 9x⁴y - 6x³y² + 3x²y³ is 3x²y(3x²-2xy+y²).

Answer:
A & A
Step-by-step explanation:
18)the graph of the function is stretched by half, thus it compresses toward the x axis. while the +4 in the root is moved 4 to left.
19) set equations equal to each other and solve for x and y one at a time
