Which of these is a prime number?<br> 733<br> 712<br> 702<br> 725

marishachu [46]

Answer:

733

Step-by-step explanation:

712 and 702 end in 2, so they're divisible by 2.

725 ends in 5, so it's divisible by 5.

733 is not divisible by 2.

7 + 3 + 3 = 13, so 733 is not divisible by 3.

It looks like 733 is the prime number.

What is the probability she will roll a number divisible by 3?

Len [333]

Answer: G. 33.3%

Step-by-step explanation:

From 1 to 12, there are four numbers divisible by 3: 3, 6, 9, 12. Since there are 12 numbers in total, that means you have a 4/12 chance of picking a number divisible by 3, which when converted to decimal from 1/3 is 33.3%

Graph h(x)=7 sin x ?

dedylja [7]

Answer:

The graph of h(x) is shown below.

Step-by-step explanation:

The given function is

$h(x)=7\sin x$

The general form of sine function is

$f(x)=a\sin(bx+c)+d$

Where, a is amplitude, b is period, c is phase shift and d is vertical shift.

So, the amplitude of the given function is 7, period is 1, phase shift is 0 and vertical shift is 0.

It means the minimum value of function is -7 and maximum value is 7.

Therefore the points on the function are (0,0), $(-\frac{\pi}{2},-7),(\frac{\pi}{2},7)$ .

The graph of function is shown below.

The lines 2x=ky+2 and (k+1)x=6y-3 have same gradient. Find possible values of k

faust18 [17]

Answer:

k = 3 or k = -4

(Anyone can correct me if I'm wrong)

Step-by-step explanation:

$2x=ky+2\to\ eq1\\(k+1)x=6y-3\to\ eq2\\$Change to this form: $y=mx+c\\ky=2x-2\\y=\frac{2x-2}{k}\\$gradient of eq1: $\frac{2}{k}\\6y=(k+1)x+3\\y=\frac{(k+1)x+3}{6}\\y=\frac{k+1}{6} x+\frac{3}{6}\\y= \frac{k+1}{6} x+\frac{1}{2}\\$gradient of eq1: $\frac{k+1}{6}\\$Since gradient, m, is the same for both lines,$\\\frac{2}{k}=\frac{k+1}{6}\\12=k^{2}+k\\k^{2}+k-12=0\\(k-3)(k+4)=0\\k=3 $ or $ k=-4$
