If the polygons are similar, the corresponding sides are proportional.

corresponding sides:

AE - BD

AB - ED

BC - DC

AC - EC

You have proportions:

$\dfrac{AE}{BD}=\dfrac{AC}{BC}=\dfrac{EC}{DC}\\\\\dfrac{AB}{ED}=\dfrac{BC}{DC}=\dfrac{AC}{EC}$

and their modifications

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

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

ira [324]

Answer:(7x3)+(4x24)=117

Step-by-step explanation:

Since he needs 3 feet of wood and it is 7 dollar per foot, you need to multiply 7 by 3. Since he needs 4 pieces of glass and its 24 dollars per glass multiply 4 by 24. Add the products. Ur done!

A polynomial is to be constructed that will touch the x axis at most 8 times. What is the minimum degree of the polynomial?

slamgirl [31]

Every degree is a touching point since each root factor is an x intercept

therefor the answer is 8th degree
