Answer:

6.3125 m/s

Step-by-step explanation:

When acceleration is uniform, the average velocity over the interval is the average of the starting and ending velocities:

(0 +12.625 m/s)/2 = 6.3125 m/s

mark is going to work for his father’s pool cleaning business during the summer. mark’s father will pay him $5 each pool he help

vfiekz [6]

Answer:

Algebraic Expression: 5<em>n</em>

a. 5(15) = 75$

b. 5(25) = 125$

c. 5(35) = 175$

d. 5(45) = 225$

Step-by-step explanation:

If <em>n</em> represents the amount of pools Mark has cleaned, and he earns $5 for each pool, then 5n will be the algebraic expression. As <em>n</em> represents the number of pools he has cleaned, we need to <u>plug in</u> the given numbers to get the answer, hence [5(15), 5(25), 5(35), 5(45)]. Multiply $5 by the given numbers to get the amount of money Mark would earn if he cleaned the amount of pools.

Which of the following constants can be added to x2 - 3x to form a perfect square trinomail?

serious [3.7K]

The constant that can be added to $x^2$ - 3x to form a perfect square trinomial is $2\frac{1}{4}$

The given expression is

$x^2$ - 3x

To form a perfect square trinomial

$(a-b)^2 =a^2-2ab+b^2$

The given expression is

$x^2$ - 3x

first we have to add a constant term with it

$x^2$ - 3x + z

By comparing the given expression and the perfect square trinomial

$a^2 =x^2$

a = x

Similarly

-2ab = 3x

where know a =x

Then,

-2b = 3

b = -3/2

Similarly

$b^2 = z$

$(\frac{-3}{2})^2$ = z

9/4 = z

Convert the simple fraction to mixed fraction

9/4 = $2\frac{1}{4}$

Hence, the constant that can be added to $x^2$ - 3x to form a perfect square trinomial is $2\frac{1}{4}$

The complete question is :

Which of the following constants can be added to x2 - 3x to form a perfect square trinomial?

$1\frac{1}{2},2\frac{1}{4}$ and $4\frac{1}{2}$
