Oil leaked from a tank at a rate of r(t) liters per hour. the rate decreased as time passed, and values of the rate at two hour
Galina-37 [17]
The given data is
t, h:            0     2     4     6     8   10
r(t), L/h:   8.6  7.9  6.8  6.4  5.7  5.3

The lower and upper estimates for the total amount that leaked may be computed as the Left and Right Riemann sums.

The shape of the graph of r versus will determine which of the two sums yields an upper or lower sum.
The plot of the graph is shown below.

The Left Riemann sum is
Sl = 2*(8.6+7.9+6.8+6.4+5.7) = 70.8 L

The Right Riemann sum is
Sr = 2*(7.9+6.8+6.4+5.7+5.3) = 64.2 L

Answer:
The lower estimate for oil leakage is 64.2 L
The upper estimate for oil leakage is 70.8 L

Find the ratio of two complement angle is 2:3. Find the angles.​
Aliun [14]

Answer:

The angles are 2x= 2x18°   =36° and  3x=3×18   =54°  

Step-by-step explanation:

It is given that two complementary angles are in the ratio 2:3.

Consider 2x and 3x as the angles.

We know that, if two angles are complementary, then their sum is 90°    .

Then, 2x+3x=90°  

 ⟹ 5x=90°  

⟹ x=  90/5

​  x=18°  

Here, the angles will be 2x=2×18   °=36°  

 and 3x=3×18°   =54  °

Hope this helps.

Viktor [21]

Answer:

Answer is 109/25000

Step-by-step explanation:

By applying formula:

P= 1/100,000

Now putting values accordingly of 1 grand prize and third prize we get:

P= 1+5+30+400/100000

= 436/100000

= 109/25000
