Answer:

I don't know what it means by "models the sequence" yet, but here is an equation describing the sequence if it helps any: x2 + (x.5)

Answer:

The first term is 80 and the common ratio is 2.5 because every term is being multiplied by 2.5. to figure this out when it is not obvious, divide the 2nd term by the first term. the equation is y = 80(2.5)^x

Need answer for this ratios question

Answer: 4:1

Step-by-step explanation: I think the answer is 4:1. I think this because 20% of 2500, would be 500. So 2500-500=2000. So the ratio would be 2000:500. Then we simplify 2000:500, by dividing 2000 by 500, and dividing 500 by 500. 500 / 500 = 1. 2000 / 500 = 4, so the answer is 4:1. (I am sorry if I am incorrect)

Match the mean, median, mode, and range for the data set below. 2, 7, 8, 4, 8, 2, 5, 5, 7, 2

dusya [7]

Answer:

Mean - 5

Median - 5

Mode - 2

Range - 6

Step-by-step explanation:

Mean-

If you add 2 + 7 + 8 + 4 + 8 + 2+ 5+ 5+ 7 +2= 50

50 divided by 10 (the amount of numbers in the equation) = 5 for the mean

Median-

Put the numbers in order which is

2,2,2,4,5,5,7,7,8,8 and the number is the middle is 5

Mode-

The number that repeats the most is 2

Range-

The largest number is 8 and the smallest number is 2 so 8-2=6

Let f = (ax + by + 4z) i + (x + cz) j + (9y + mx) k where a, b,c, and m are constants.

Tom [10]

Let $\mathcal R$ be an arbitrary closed region with boundary the surface $\mathcal S$ . By the divergence theorem,

$\displaysytle\iint_{\mathcal S}\mathbf f(x,y,z)\cdot\mathrm d\mathbf S=\iiint_{\mathcal R}\nabla\cdot\mathbf f(x,y,z)\,\mathrm dV$

We have

$\nabla\cdot\mathbf f(x,y,z)=\dfrac{\partial(ax+by+4z)}{\partial x}+\dfrac{\partial(x+cz)}{\partial y}+\dfrac{\partial(9y+mx)}{\partial z}=a$

so that the flux satisfies

$\displaystyle a\iiint_{\mathcal R}\mathrm dV=0$

We're assuming $\mathcal R$ is a closed region, and the integral above is its volume, which must be positive. This means we must have $a=0$ .
