Answer:

The domain of the function is R i.e. any real value.

Step-by-step explanation:

The given figure is a graph on the coordinate plane of the function y = 10^{x}

Now, the domain of a function means that the values of x (Independent variable) for which the function is valid i.e. the y values are real.

It is clear from the equation given above that for any real value of x there will be a real corresponding value of y.

Therefore, the domain of the function is R i.e. any real value. (Answer)

Which multiplication expression is equivalent to
oee [108]

Answer:

1

Step-by-step explanation:

Correct question:  2x2 - 5x - 3 / 4x2 + 12x + 5 divided by 3x2 - 11x + 6 / 6x2 + 11x - 10.

As given: \frac{(2x^{2}-5x-3) }{(4x^{2}+12x+5 )} \div \frac{(3x^{2} -11x+6)}{(6x^{2}+11x-10) }

Solving it by using quadratic equation.

= \frac{(2x^{2}-6x+1x-3) }{(4x^{2}+10x+2x+5) } \div \frac{(3x^{2}-9x-2x+6 }{(6x^{2}+15x-4x-10) }

= \frac{(2x+1) (x-3)}{(2x+1) (2x+5)} \div \frac{(3x-2) (x-3)}{(2x+5) (3x-2)}

To divide fraction take the reciprocal of divisor and multiply the dividend.

= \frac{(2x+1) (x-3)}{(2x+1) (2x+5)} \times \frac{(2x+5) (3x-2)}{(3x-2) (x-3)}

We solve it to get 1 as it cancel fraction on both side.

Answer is 1.

Height of men on a baseball team have a bell-shaped distribution with a mean of 180 cm and a standard deviation of 8 cm. using t
Lapatulllka [165]

Answer:

a. 99.7%

b. 68%

Step-by-step explanation:

The empirical rule for approximately symmetrical and bell-shaped distributions states that:

68% of the data are among the values  (means - sd) and (means + sd)

95% of the data are among the values  (means - 2*sd) and (means + 2*sd)

99.7% of the data are among the values (means - 3*sd) and (means + 3*sd). So that,

68% of the data are among the values  (180 - 8) = 172 and (180 + 8) = 188

95% of the data are among the values  (180 - 16) = 164 and (180 + 16) = 196

99.7% of the data are among the values (180 - 24) = 156 and (180 + 24) = 204
