Which statement best describes the polynomial 2x + 8?

1 answer:

7 0

There are two (2) terms, "2x" and "8", making it a "binomial" (the "bi" prefix meaning "two"). The only variable is x, and its power is 1, making the "2x" term a first-degree term. Since the highest degree of any term is 1, the polynomial is first degree.

Selection A is appropriate.

A circle with area 9 pie has a sector with a central angle of 17/9 pie radians .

zmey [24]

Answer: 8.5π

Step-by-step explanation:

If I understand the question correctly, the entire circle has an Area of 9π and you are looking for the Area of the shaded region which has a central angle of $\dfrac{17}{9}\pi$

the section of the circle that is shaded is $\dfrac{\dfrac{17}{9}\pi}{2\pi}=\dfrac{17\pi}{18\pi}=\dfrac{17}{18}$

Area of the shaded region is: $9\pi \cdot \dfrac{17}{18}=\dfrac{17}{2}\pi=8.5\pi$

A newborn blue whale weighs 3^7 an adult blue whale weighs 81 times a new way of the newborn how many kilograms does the dog blu

mrs_skeptik [129]

Answer:

3^11 kilogram

Step-by-step explanation:

We were told a newborn blue whale weighs 3^7

But an adult blue whale weighs 81 times a new way of the newborn this can be expressed below as

=81×3^7

This can be expressed in standard form as

3^4 × 3^7

Then we need to determine number of kilograms the adult blue whale weigh.

81=3^4

=3^11

Therefore, number of kilograms the adult blue whale weigh 3^11kg
