On Monday you sent x number of text messages. On Tuesday you sent twice as many. On Wednesday you sent 12 more texts than you se

Lady bird [3.3K]

Answer:

Expression representing number of text messages sent on Tuesday = 2x , where x = text messages sent on Monday

Step-by-step explanation:

Let number of messages sent on Monday = x

So, number if messages sent on Tuesday = 2 times x = 2x

Number of texts sent on Wednesday = 12 more than texts sent on Tuesday = 2x + 12

Number of texts sent on Thursday = Half the texts sent on Wednesday = 1/2 (2x + 12) = x + 6

Evaluate the Riemann sum for (x) = x3 − 6x, for 0 ≤ x ≤ 3 with six subintervals, taking the sample points, xi, to be the right e

DENIUS [597]

Hello,

Reminders:
$$\sum_{i=1}^{n} i= \dfrac{n(n+1)}{2}$


$
$$ \sum_{i=1}^{n} i^2= \dfrac{n(n+1)}{2}$

$
$$ \sum_{i=1}^{n} i^3= \dfrac{n^2(n+1)^2}{4} $
$

$n=6\\
x_{0}=0\\
x_{n}=3\\
\Delta= \dfrac{x_n-x_0}{n}=0.5\\

$
$x_{i} =0+\Delta*i= \frac{i}{2}$

$\sum_{i=1}^{n}\ \Delta*f(x_{i})=\sum_{i=1}^{6}\ \dfrac{i^3/8-6i}{2}$
$$= \dfrac{1}{2}\sum_{i=1}^{6} (\frac{i^3}{8} -6i)=\dfrac{1}{16}*\frac{(6*7)^2}{4}- \frac{9*7}{2}= -3.9575$

9, 19, 29, 39, 49
So there are 5 houses with 9s painted
