Factor the polynomial.<br><br> X2+3x-54

Harrizon [31]

Answer:

<h2> $\mathrm{(x + 9)(x - 6)}$ </h2>

Step-by-step explanation:

${x}^{2} + 3x - 54$

Write 3x as a difference

${x}^{2} + 9x - 6x - 54$

Factor out x from the expression

$x(x + 9) - 6x - 54$

Factor out -6 from the expression

$x(x + 9) - 6(x + 9)$

Factor out x+9 from the expression

$(x + 9)(x - 6)$

Hope I helped!

Best regards!

Answer:

-0.0205 < p1 - p2 < 0.6631

Step-by-step explanation:

Here we need to use the formulas for a confidence interval using a difference of 2 given proportions.

Proportion 1 (small cars) = 8/13

Proportion 2 (large cars) = 5/17

A 95% confidence level has a z-score of 1.96 (the method of looking up z-scores doesn't change with using two proportions instead of 1)

See attached photo for formulas and solutions, and the construction of the confidence interval...

Use the product of powers property to simplify the numeric expression.

motikmotik

Answer:

The value of $4^{\dfrac{1}{3}} {\cdot} 4^{\dfrac{1}{5}$ is $4^{\dfrac{8}{15}}$ .

Step-by-step explanation:

We need to simplify the numeric expression using property. The expression is as follows :

$4^{\dfrac{1}{3}} {\cdot} 4^{\dfrac{1}{5}$

The property to be used is : $x^a{\cdot} x^b=x^{a+b}$

This property is valid if the base is same. Here, base is x.

In this given problem, x = 4, a = 1/3 and b = 1/5

So,

$4^{\dfrac{1}{3}} {\cdot} 4^{\dfrac{1}{5}}=4^{\dfrac{1}{3}+\dfrac{1}{5}}\\\\=4^{\dfrac{5+3}{15}}\\\\=4^{\dfrac{8}{15}}$

So, the value of $4^{\dfrac{1}{3}} {\cdot} 4^{\dfrac{1}{5}$ is $4^{\dfrac{8}{15}}$ .

Find the area of the shaded region

Novay_Z [31]

3.14159(pi) times radius squared
pi times 24 squared equals 1809.56
now find the area of the smaller circle
pi times 6 squared equals 113.1
now subtract the smaller circle from the bigger circle
1809.56 minus 113.1
answer is 1696.46
