Answer:

Yes,he can go to scuba diving

Step-by-step explanation:

Given the has $118 american dollars

Also given that the relation betweeen the australian and american currency is y = 1.03x where y is the amount in australian currency and x is the amount in the american currency.

Now we have x= 118.

y=1.03\times118=121.54

So the guy has $121.54 Australian dollars and the scuba diving is $120 Australian dollars.Since it cost's less he can afford the scuba diving.

Use Wolframalpha to find the exact volume of the solid obtained by rotating about x = [pi]/2 the region bounded by y = sin^2x, y
Alex777 [14]

Answer:

Step-by-step explanation:

Here the region between two curves is rotated about a vertical line.

The functions are

y = sin^2x, \\y = sin^4x, \\x in [0,[pi]/2].

Intersecting points are x=0 and x =pi/2

Since rotated about x = pi/2 we get

using cylindrical shell method

Volume = 2\pi rh\\=2\pi \int\limits^\frac{\pi}{2} _0 {xy} \, dx \\=2\pi  \int\limits^\frac{\pi}{2} _0 (x+\frac{\pi}{2} )(sin^2 x -sin^4 x) dx\\

From wolfram alpha we find that

Volume= 2\pi (\frac{3\pi^2 }{64)} =\frac{6\pi^3}{64}

Y-1=2/3(x+9) in standard form
UNO [17]
First, distribute 2/3 to the values in the parentheses. This gives you y-1=2/3x+6.

To get y alone, we add 1 to both sides. This gets you y=2/3x+7.

y=mx+b
y=2/3x+7

It matches the standard form, so your final answer would be y=2/3x+7.

9. All the students in the sixth grade either walk home or take the bus home after scho
timurjin [86]

There are 250 students in sixth grade

<em><u>Solution:</u></em>

Given that, All the students in the sixth grade either walk home or take the bus home after school

From given,

Number of students walk home = 170

Let "x" be the total number of students in school

32% of the students take the bus

Thus, 32 % of "x" takes bus

<em><u>To find: total number of students in school</u></em>

Total students = Number of students walk home + number of students takes bus

x = 170 + 32 \% \times x\\\\x = 170 + \frac{32}{100} \times x\\\\x = 170 + 0.32x\\\\x - 0.32x = 170\\\\0.68x = 170\\\\x = 250

Thus there are 250 students in sixth grade
