Answer:

1100 mm = 1.1 m, and 900 mm = 0.9 m.

So the area is 1.1 x 0.9 = 0.99 m^2

If m1=2x° and m3=3x° what is m1

olga_2 [115]

Answer:

Step-by-step explanation:

Using the angle addition postulate

angle 1+angle 2+angle 3=180

Angle 2 is 90 degrees,

Angle 1 is 2x degrees

Angle 3 is 3x degrees

Plug this into equation

$2x + 90 + 3x = 180$

$5x + 90 = 180$

$5x = 90$

$x = 18$

Plug 18 into 2x

$2(18) = 36$

a bowl contains 24 marbles consisting of 6 whilte, 8 blue 7 black and 3 red. WHat is the probaility of drawing a black marble?

Anit [1.1K]

Probability helps us to know the chances of an event occurring. The probability of choosing a black marble from the bowl is 0.2917.

<h3>What is Probability?</h3>

Probability helps us to know the chances of an event occurring.

Probability=(Desired Outcomes)/(Total Number of possible outcomes)

The total number of marbles in the bowl is 24, while it contains 6 white, 8 blue, 7 black and 3 red. Therefore, the probability of choosing a black marble from the bowl is,

P(Black marble) = Number of black marble/Number of total Marble

P(Black Marble) = 7/24 = 0.2917

Hence, the probability of choosing a black marble from the bowl is 0.2917.

The curve with equation y=e^2x/4+3e^x has one stationary point.find the exact value of the coordinates of this point

Softa [21]

$y=\dfrac{e^{2x}}{4+3e^x}$
$\implies y'=\dfrac{2e^{2x}(4+3e^x)-3e^xe^{2x}}{(4+3e^x)^2}$
$\implies y'=\dfrac{8e^{2x}+3e^{3x}}{(4+3e^x)^2}$

Stationary points occur where the derivative is zero. The denominator is positive for all $x$ , so we only need to worry about the numerator.

$8e^{2x}+3e^{3x}=e^{2x}(8+3e^x)=0$

$e^{2x}>0$ for all $x$ , so we can divide through:

$8+3e^x=0\implies e^x=-\dfrac83$

But $e^x>0$ for all $x\in\mathbb R$ , so this function has no stationary points...

I suspect there may be a typo in the question.
