NoThe equation is not quadratic in form.The variable part of the first term is not the square of the variable part of the
second term.The result of squaring x cubed is x to the 6thpower, not the 9th power.x9 (x3)2

The given equation, x9 - 5x3 + 6 = 0, is not a quadratic equation because the exponent of the first term is 9 while that of the second term is 3. The square of 3. If we are to square x3, we should only be getting x6 instead of x9. Therefore, the answer is NO.

Answer:

Her share is $3500

Step-by-step explanation:

As a general rule, if they did not make any specifications on how they would share the profit, then they should share it according on how percentage of capital they contributed. Since Elisa only contributed 10%, then she should get only 10% of profit, as a result, her share is 35000*0.1 = $3500.

The radius of a circle is 13miles. what is the area of a sector bounded by a 20 degree arc

Stolb23 [73]

Answer:

Area of the sector = 29.48 square miles.

Step-by-step explanation:

Given:

Radius of a circle = 13 miles

Angle bounded by the arc = 20 deg

To find

Area of the sector bounded by 20 degrees.

Note: Area of a sector = $\frac{(\theta)}{360}\times \pi\times r^2$

Plugging the values in the equation.

⇒ $\frac{(\theta)}{360}\times \pi\times r^2$

⇒ $(\frac{20}{360})\times 3.14\times 13^2$

⇒ $29.48$ square-miles

So the area of the sector bounded by 20 degree arc is 29.48 square miles.

Answer:

$44.49

Step-by-step explanation:

The total cost before tax will be ...

$49.96 +49.96 + 0.50(49.96) = $124.90

With tax added, the cost is ...

$124.90 × 1.071 = $133.77

Then the average cost per shirt for the 3 shirts is ...

$133.77/3 = $44.59

The mean cost of a shirt is $44.59.
