Answer:

1. 11x36=396

penjelasan: Cara cepetnya pertama taro 3 di awal 6 diakhir teruskan tengahnya kita gatau isinya berapa jadi caranya 3 plus 6 jadi 9 jadi hasilny 396.

2. 20x30 = 600

3. 35 + 15 = 50

4. 100x (25-12) = 1300

5. 60 + 20 + 30 = 110

6. 100 % + 200 % = 300 %

7. 25/4 x 100 = 625

8. cos 210 = 1/2 akar 2

9. 999 - 99 = 900

10. 24/33 x 11 = 8

Need help with question 11 and 12

qaws [65]

Answer:

11. your choices are correct

12. 132°

Step-by-step explanation:

11. The given equations can be (re)written to slope-intercept form. Only those lines with a slope of 2 will be parallel to the given line.

A: y = 2x -8 . . . . . slope = 2, an answer

B: y = -2x +1 . . . . . slope = -2, not an answer

C: y = -2x +7 . . . . .slope = -2, not an answer

D: y = 2x +2 . . . . . slope = 2, an answer

E: y = -2x -9 . . . . . slope = -2, not an answer

12. The marked angles are supplementary, so ...

(3x -6)° +(x +2)° = 180°

4x -4 = 180 . . . . . . . . . . . divide by °, collect terms

x -1 = 45 . . . . . . . divide by 4

x = 46 . . . . . . . . . add 1

Now, we can find the angle of interest.

∠PQR = (3x -6)° = (3·46 -6)°

∠PQR = 132°

Identify whether the series sigma notation infinity i=1 15(4)^i-1 is a convergent or divergent geometric series and find the sum

const2013 [10]

Answer: The correct option is

(d) This is a divergent geometric series. The sum cannot be found.

Step-by-step explanation: The given infinite geometric series is

$S=\sum_{i=1}^{\infty}15(4)^{i-1}.$

We are to identify whether the given geometric series is convergent or divergent. If convergent, we are to find the sum of the series.

We have the D' Alembert's ratio test, states as follows:

Let, $\sum_{i=1}^{\infty}a_i$ is an infinite series, with complex coefficients $a_i$ and we consider the following limit:

$L=\lim_{i\rightarrow \infty}\dfrac{a_{i+1}}{a_i}.$

Then, the series will be convergent if L < 1 and divergent if L > 1.

For the given series, we have

$a_i=15(4)^{i-1},\\\\a_{i+1}=15(4)^i.$

So, the limit is given by

$L\\\\\\=\lim_{i\rightarrow \infty}\dfrac{a_{i+1}}{a_i}\\\\\\=\lim_{i\rightarrow \infty}\dfrac{15(4)^i}{15(4)^{i-1}}\\\\\\=\lim_{i\rightarrow \infty}\dfrac{15(4)^i}{15(4)^{i}4^{-1}}\\\\\\=\dfrac{1}{4^{-1}}\\\\=4>1.$

Therefore, L >1, and so the given series is divergent and hence we cannot find the sum.

Thuds, (d) is the correct option.
