Answer: x=2 - 1/2 x ㏒(16/2953125)

Step-by-step explanation:

log (28^2) + log(525^-3) + 2x=log(10^4)
log(28^2 x 1/523^3) + 2x=4
log(28^2/525^3) + 2x=4
log (112/75 x 75 x 525) + 2x=4
log(16/2953125) + 2x=4
2x=4-log(16/2953125)
x=2-1/2 x log(16/2953125)

Evaluate the following using powers of ten rules. 104)1.042

Alinara [238K]

Answer:

0.0001042

Step-by-step explanation:

Power of tens rule states that if the denominator of a fraction has the positive power of 10, decimal in the numerator will be shifted to the left by the same number of places as exponent.

10⁴) 1.042 = $\frac{1.042}{10^4}$

In the denominator of the given fraction, exponent of 10 = +4

So the decimal in numerator will be shifted left by 4 places.

$\frac{1.042}{10^4}=0.0001042$

Therefore, answer is 0.0001042

Graph the function rule. Tell whether the graph is continuous or discrete. The height h, in inches, of the juice in a 20-oz b

tangare [24]

The x-axis is the amount of juice because it is the independent equation, while the y-axis is the height. The range of the x-axis starts from 0 to the maximum 20 oz. The graph is shown in the attached picture. As shown, the graph is continuous.

Can someone answer fast.plsss

Anika [276]

Answer:

Step-by-step explanation:

sec (thita) = squrt (5)

squaring on both sides:

sec^2 (thita) = 5 - equation 1

1 + tan^2 (thita) = 5

tan^2 (thita) = 4

tan (thita) = 2.

= tan (thita) - squrt(5)sin(thita)

= 2 - squrt(5) x 2/ squrt(5)

= 0

from eqn - 1

sec(thita) = squrt(5)

cos(thita) = 1/ squrt(5)

sin(thita) = squrt ( 1- 1/(squrt (5))^2)

sin(thita) = 2/ squrt(5) .
