8.) a round patio is 14m in diameter. What is the distance around the patio? A. 153.86m B. 21.98m C. 43.96m D. 615.44m

professor190 [17]

So by having a circle with a diameter of 14 metres it is a sake of calculating the circumference of the patio. This is simply done by (where d = 2r, d is the diameter, and r the radius)

$C = 2\pi r = 2\cdot \pi \cdot \left \frac{14}{2} \text{ m} \approx 43.98 \text{ m}$

What is the remainder when (3x4 + 2x3 − x2 + 2x − 19) ÷ (x + 2)?

mel-nik [20]

Answer: The remainder will be 5 only.

Explanation:

Since we have given that

$f(x)=3x^4+2x^3-x^2+2x-19$

and

$g(x)=x+2$

Now, using the division algorithm, we'll get,

$f(x)=g(x)\times (3x^3-4x^2+7x-12)+5$

When we compare it with division lemma, which says that

$f(x)=g(x)\times q(x)+r(x)$

We get,

$r(x)=5$

Hence, the remainder will be 5 only.
