Hello, I need help with this question, please and thank you.
dangina [55]

Step-by-step explanation:

It appears that given geometrical shape is a HEXA-DECAGON or a 16 sided polygon.

Measure of one interior angle of hexa-decagon can be given as:

\frac{(n - 2) \times 180 \degree}{n}  \\  \\  =   \frac{(16 - 2) \times 180 \degree}{16} \\  \\  =   \frac{14 \times 45 \degree}{4} \\  \\ =   \frac{7 \times 45 \degree}{2} \\  \\  = \frac{315 \degree}{2}  \\  \\  = 157.5\degree \\

HELP!!!! Position and label the triangle on the coordinate plane
Darya [45]

Answer:

Option (2).

Step-by-step explanation:

It is given in the question,

ΔLMN is a right triangle with base LM = 3a units

Hypotenuse MN = 5a

By applying Pythagoras theorem in ΔLMN,

MN² = LM² + NM²

(5a)² = (3a)² + MN²

25a² - 9a² = MN²

MN = √16a²

MN = 4a

Therefore, vertices of the triangle will be L(0, 0), M(3a, 0) and N(0, 4a).

Option (2) will be the answer.

Given P(x) = 2x3+ 3x2- x + 4, find P(0) and P(-2).
pshichka [43]

9514 1404 393

Answer:

  P(0) = 4

  P(-2) = 2

Step-by-step explanation:

Put the value where the variable is and do the arithmetic.

  P(0) = 2·0³ +3·0² -0 +4

  P(0) = 4

__

  P(-2) = 2·(-2)³ +3·(-2)² -(-2) +4 = 2(-8) +3(4) +2 +4

  P(-2) = -16 +12 +2 +4

  P(-2) = 2

GalinKa [24]

Answer:

he should buy 128 oz of milk for 6.49

Step-by-step explanation:

2.49 divided by 32 equals 7 cents unless your rounding which would be 8 cents

4.99 divided by 64 is 7 cents too 8 if rounding

6.49 divided buy 128 oz would equal 5 cents so it is the cheapest.

Select the equation of the line that passes through the point (5, 7) and is perpendicular to the line x = 4.
Dmitry_Shevchenko [17]
Yes, I think the answer is y = 7. The line x = 4 runs vertical (because all of the points in that line have an x-value of 4) so any line that is perpendicular to it has to be horizontal. Any line that is horizontal is in the form y = (some number). In order for the new line to run through the point (5,7) it would have to have the same y-value as that point, which is 7. So the new line is y = 7. Hope this helps :) (P.S. try graphing them both if you need a visual.)
