2 7/9x2/3 please help
Furkat [3]

Answer:

Improper: 2 42/9  proper: 6 6/9

Step-by-step explanation:

2 7/9 x 2/3

find the common denominator which is 9 so now we have,

2 7/9 x 2/9

find the numerator which is,

2 7/9 x 6/9

multiply

2 42/9

This fraction is improper so lets make it proper,

42 goes into 9 four times

so we have,

6/9 + 2 + 4

final answer,

6 6/9

1) Factor the expression and use the fundamental identities to simplify. There is more than one correct form of the answer.
Art [367]

Answer:

Step-by-step explanation:

1) 6 tan2x − 6 tan2x sin2x

=6tan2x(1-sin2x)\\= 6tan2x (sin^2 x + cos^2 x -2sinx cosx)\\= 6tan2x (sinx+cosx)^2\\

2) \frac{3}{1+cos x} +\frac{3}{1-cosx} \\=\frac{3-cosx+3+cosx}{1-cos^2 x} \\=\frac{6}{sin^2 x} \\=6 cosec^2 x

3) \frac{sin^2 y}{1-cosy } =\frac{1-cos^2 y}{1-cosy }\\=1+cosy

4) x=6cos t

So cost =x/6

sint = \frac{\sqrt{36-x^2} }{\{6 } \\

so -3sint

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h where r is the radius and h is the height

V = (3.14) * (7)^2 * 8

V = 3.14 * 49*8

V =1230.88

Which of the statements are true about the function f given by f(x) = 100-e? Select all that apply.
tatiyna

From the above function, it is clear that the value of f is never 0. Hence the statement that is true is (Option E), See explanation of same below.

<h3>What is the explanation for the above function?</h3>

Note that the function is related to Euler's number which is depicted as:
e ≈ 2.7182. The function is given as:

f(x) = 100 * e^{-x}

Assuming x = -2, we'd have:

100 * 2.7182^{-2}

= 271.82^{-2}

= 0.00001353354

Hence, even when x tends < 0 the function f(x) thus, is never 0. See the attached graph for confirmation.
