Answer:

0, 5, 7, 11, ...

Step-by-step explanation:

1^2 = 1; 1 - 1 = 0; 0 is divisible by 6

5^2 = 25; 25 - 1 = 24; 24 is divisible by 6

7^2 = 49; 49 - 1 = 48; 48 is divisible by 6

11^2 = 121; 121 - 1 = 120; 120 is divisible by 6

There are 47 students in a class and 35 of these students passed their Geometry test.

Dafna11 [192]

Answer:

74.47%

Step-by-step explanation:

Divide the total number of students by the number who passed

passed/total

35/47

0.74468085

As a percent:

0.74468085*100=74.4680851

Rounded to the nearest hundreth:

74.4680851

74.47%

So, 74.47% passed the geometry test

Hope this helps! :)

An oil tanker breaks apart and starts leaking. As time goes on, the rate at which the oil is leaking out will diminish. Suppose

Alborosie

Answer:

62.77 million gallons

Step-by-step explanation:

Given,

The function that shows rate of leaking oil per minute in after t hours,

$R(t) = \frac{0.7}{1+t^2}$

∵ 1 hour = 60 minutes ⇒ 3 hours = 180 minutes,

Hence, the quantity of oil leaked out in the first 3 hours,

$V(t) = \int_{0}^{180} R(t) dt$

$=\int_{0}^{180} \frac{0.7}{1+t^2} dt$

$=0.7 \int_{0}^{180} \frac{dt}{1+t^2}$

$=0.7[tan^{-1}(t)]_{0}^{180}$

$=0.7(tan^{-1}(180) - tan^{-1} (0))$

$=0.7(89.68)$

= 62.77 million gallons

Answer:

$f^{-1}(x) = 4x-3$ is the right answer.

Step-by-step explanation:

I the function is $f(x) = \frac{x+3}{4}$

$f(x)=\frac{1}{4}(x+3)$

Then we have to find inverse of function f(x).

we will write the equation as $y=\frac{1}{4}(x+3)$

4y = x + 3

x = 4y - 3

Now we will rewrite the function as

$f^{-1}(x) = 4x-3$

So the answer is $f^{-1}(x) = 4x-3$
