__,__, 8.16,32,64 what is the arithmetic sequence?
seraphim [82]

Answer:

2,4,8,16,32,64

Step-by-step explanation:

There are a couple of ways one could approach this. The goal is to find out the factor by which the numbers are increasing. Looking at going from 8 -> 16, we have either added 8, or doubled 8. So the factor is either +8 or x2. Going from 16 -> 32, adding 8 no longer holds true, while multiplying by 2 (doubling 16) does. To confirm what we have found, we can further check our math by using the final two numbers, 32 -> 64, to confirm that the sequence pattern is to double the current number to achieve the next number.

Working backwards, we can half each number to find out the first two numbers in the sequence. 64/2 = 32, 32/2 = 16, 16/2 = 8, 8/2 = 4, 4/2 = 2

Find the surface area of the part of the sphere x2+y2+z2=81 that lies above the cone z=x2+y2−−−−−−√
TiliK225 [7]
Parameterize the part of the sphere by

\mathbf s(u,v)=(9\cos u\sin v,9\sin u\sin v,9\cos v)

with 0\le u\le2\pi and 0\le v\le\dfrac\pi4. Then

\mathrm dS=\|\mathbf s_u\times\mathbf s_v\|=81\sin v\,\mathrm du\,\mathrm dv

So the area of S (the part of the sphere above the cone) is given by

\displaystyle\iint_S\mathrm dS=81\int_{v=0}^{v=\pi/4}\int_{u=0}^{u=2\pi}\sin v\,\mathrm du\,\mathrm dv=81(2\pi)\left(1-\dfrac1{\sqrt2}\right)=(162-81\sqrt2)\pi

Tess plants flowers every year, and she noticed that her flowers tend to bloom earlier when the spring weather is warmer. She co
OlgaM077 [116]

Answer:

=17

Step-by-step explanation:

We need the slope and the y-intercept to find the equation of the linear model.

This line goes through (0,28) and (1,26), so the slope is

\frac{26 - 28}{1} = -2

1

26−28

​  =−2

The equation that best describes this model is

\widehat{y} = -2x + 28

y

​  =−2x+28

Plug in x = 5.5 in the above equation to get

​\widehat{y}

y

​   ​=−2x+28

=(−2)(5.5)+28

=−11+28

=17

Based on this equation, the date in April her flowers will bloom if the average temperature in March is
