Answer:

1

Step-by-step explanation:

you simply divide 154 by 9, get around 17.1. 17 is the closest whole number answer, so 17*9 is 153.

do 154-153, you get 1.

not the best explaination but i hope it helps.

Answer:

$946$

Step-by-step explanation:

we know that

The formula to find the sum is equal to

$S=(a1+an)n/2$

where

a1 is the first term

an is the last term

n is the number of terms

In this problem we have

$n=11$

$a1=(98-2(1))=96$

$an=(98-2(11))=76$

substitute the values in the formula

$S=(96+76)(11/2)=946$

If P(x) = P<img src="https://tex.z-dn.net/?f=_%7Bn%7D" id="TexFormula1" title="_{n}" alt="_{n}" align="absmiddle" class="latex-f

seropon [69]

If $P(x) = p_nx^n + p_{n-1}x^{n-1}+\ldots+p_0$ is divided by $(x-a)$ , then $P(x) = (x-a) \cdot Q(x) + R(x)$ for some polynomials $Q,R$ . Moreover, $\deg R < 1$ (because $\deg (x-a) = 1$ ), so there exists $\alpha \in \mathbb{R}$ such that $R(x) = \alpha$ for all $x \in \mathbb{R}$ . But if we calculate $P(a)$ , it turns out that $P(a) = (a-a)\cdot Q(a) + \alpha$ , so $R(x) = \alpha = P(a)$ . $\blacksquare$

S=4\pi r^{2} Solve for r[/tex]

Veronika [31]

S = 4pi r^2

S/4pi = r^2

taking square root on both sides,
r = sqrt (S/4pi)
