Answer:

x = 7/6

Step-by-step explanation:

Solve for x:

35/74 (4/3 + 21/(5 x)) - 4/5 = 23/15

Bring 35/74 (4/3 + 21/(5 x)) - 4/5 together using the common denominator 1110 x:

(2205 - 188 x)/(1110 x) = 23/15

Cross multiply:

15 (2205 - 188 x) = 25530 x

Expand out terms of the left hand side:

33075 - 2820 x = 25530 x

Subtract 25530 x + 33075 from both sides:

-28350 x = -33075

Divide both sides by -28350:

Answer: x = 7/6

Mark the statements that are true.

Answer:

Correct answers:

A. An angle that measures $\frac{\pi}{6}$ radians also measures $30^o$

C. An angle that measures $180^o$ also measures $\pi$ radians

Step-by-step explanation:

Recall the formula to transform radians to degrees and vice-versa:

$\angle\,radians=\frac{\pi}{180^o} \,* \,\angle degrees\\ \\\angle\,degrees=\frac{180^o}{\pi} \,* \,\angle radians$

Therefore we can investigate each of the statements, and find that when we have a $\frac{\pi}{6}$ radians angle, then its degree formula becomes:

$\angle\,degrees=\frac{180^o}{\pi} \,* \,\angle radians\\\angle\,degrees=\frac{180^o}{\pi} \,* \,\frac{\pi}{6} \\\angle\,degrees=\frac{180^o}{6} \\\angle\,degrees=30^o$

also when an angle measures $180^o$ , its radian measure is:

$\angle\,radians=\frac{\pi}{180^o} \,* \,\angle degrees\\\angle\,radians=\frac{\pi}{180^o} \,* \,180^o\\\angle\,radians=\pi$

The other relationships are not true as per the conversion formulas

Question 6

ad-work [718]

Answer:

The input for the method is a continuous function f, an interval [a, b], and the function values f(a) and f(b). The function values are of opposite sign (there is at least one zero crossing within the interval). Each iteration performs these steps: Calculate c, the midpoint of the interval, c = a + b2.
