Consider the function f(x) = 20/√x and its second-degree polynomial P2 (x) = 20 - 10(x-1) + 7.5(x-1)^2 at x=0.8. Compute the val

krok68 [10]

Answer:

$f (0.8) = 22.3607$ and $P_{2} (0.8) = 22.300$ .

Step-by-step explanation:

According to the statement, $f (x) = \frac{20}{\sqrt{x}}$ and $P_{2}(x) = 20 - 10 (x-1) + 7.5 (x-1) ^ 2$ . Based on these definitions, at $x=0.8$ produce:

$f (0.8) = \frac{20}{\sqrt {0.8}} = 22.3607$ . On the other hand, you have to:

$P_{2} (0.8) = 20 - 10 (0.8 -1) +7.5 (0.8 -1)^2$

$P_{2} (0.8) = 20 - 10 (-0.2) +7.5 (-0.2)^2 = 22.300$

Then, it can be affirmed that $f (0.8) = 22.3607$ and $P_{2} (0.8) = 22.300$ .

Look at the figure above: If the measure of <MNL is 43°, find the measures of the following angles. Be sure to justify each m

zimovet [89]

Answer:

NP = 43

LNO = 137

MNP = 137

Step-by-step explanation:

MNL is a vertical angle to PNO, therefore they are equal

MNL = PNO

MNL = 43 = PNO

MNL and LNO are supplementary angles. They add to 180 degrees

MNL + LNO = 180

43+LNO = 180

Subtract 180 from each side

43-43 +LNO = 180-43

LNO = 137

LNO and MNP are vertical angles. Vertical angles are equal

LNO = MNP

137=MNP
