Scientific notation The table shows the amount of money raised by each region the four regions used a total of $ (5.38×10^4) How

Serggg [28]

9514 1404 393

Answer:

$8.65×10^3

Step-by-step explanation:

The amount the West raised is the difference between the total and the sum of the other amounts raised. It is convenient to use a multiplier of 10^4 for each of the numbers, so the number for South can be rewritten as 0.675×10^4.

West = 5.38×10^4 -1.46×10^4 -2.38×10^4 -0.675×10^4

= (5.38 -1.46 -2.38 -0.675)×10^4

= 0.865×10^4 = 8.65×10^3

West raised $8.65×10^3.

Tema [17]

Answer:

option A

12m/s

Step-by-step explanation:

Given in the question,

mass of object = 11kg

kinetic energy possess by = 792 joules

To find the velocity we use formula

v = $\sqrt{\frac{2KE}{m} }$

Plug values in the formula

v = $\sqrt{\frac{2(792)}{(11)} }$

v = $\sqrt{\frac{1584}{11} }$

v = $\sqrt{144}$

v= 12 m/s

I can't understand this after "happening is" but let's do it unaided.

The number of ways to draw a boy first is 6.

Given that, the number of ways to draw a girl next is 10.

That's out of a total of 16 x 15 length two permutations of 16 things

$p = \dfrac{6 \times 10}{16(15)} = 1/4$

Answer: 1/4

Use the method of cylindrical shells to find the volume V generated by rotating the region bounded by the given curves about the

m_a_m_a [10]

Answer:

Required volume is $\frac{4864\pi}{3}$ unit.

Step-by-step explanation:

Given equations of curves,

$y=32-x^2$ , $y=x^2$

substitute second in first we will get,

$x^2=36-x^2\implies x^2=16\implies x=\pm 4$

When $x=4, y=16$ and $x=-4, y=16$ . Thus both curves intersect at the points (4,16),(-4,16). And thus $-4$ .

Considering width of the representative rectangle as $\Delta x$ which is parallel to x-axis because of considering cylindrical shell. Therefore volume of the shell is given by,
