Approximate the area under the
taurus [48]

Split up the interval [0, 3] into 3 equally spaced subintervals of length \Delta x = \frac{3-0}3 = 1. So we have the partition

[0, 1] U [1, 2] U [2, 3]

The left endpoint of the i-th subinterval is

\ell_i = i - 1

where i\in\{1,2,3\}.

Then the area is given by the definite integral and approximated by the left-hand Riemann sum

\displaystyle \int_0^3 f(x) \, dx \approx \sum_{i=1}^3 f(\ell_i) \Delta x \\\\ ~~~~~~~~~~ = \sum_{i=1}^3 (i-1)^3 \\\\ ~~~~~~~~~~ = \sum_{i=0}^2 i^3 \\\\ ~~~~~~~~~~ = 0^3 + 1^3 + 2^3 = \boxed{9}

(a+200)÷400=2 тендеу ​
Oksana_A [137]

Answer: a=600

Step-by-step explanation:

(a+200)/400=2

a+200=2×400=800 so

a+200=800

a=600 because 800-200=600

Hope this helps. Stay healthy and safe and have a blessed and wonderful day and I hope you had a good Easter!

4x - 3y = 12<br> 4x - 5y = -4<br> Solve using Elimination
mr_godi [17]

Answer:

{ \rm{4x - 3y = 12 -  -  -  \{eqn(a) \}}} \\ { \rm{4x - 5y =  - 4 -  -  -  \{eqn(b) \}}}

• subtract eqn(b) from eqn(a);

{ \underline{ \rm{  - \binom{4x - 3y = 12}{4x - 5y =  - 4} }}} \\ { \rm{0x + 2y = 16}} \\  \\ { \rm{2y = 16}} \\  \\ { \boxed{ \tt{ \:  \: y = 8 \:  \:   }}} \\

• find x :

{ \rm{4x - 3y = 12}} \\ { \rm{4x - 3(8) = 12}} \\ { \rm{4x = 36}} \\  \\ { \boxed{ \tt{ \:  \: x = 9 \:  \: }}}
