Answer:

tan

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan23° = $\frac{opposite}{adjacent}$ = $\frac{b}{4.5}$ ( multiply both sides by 4.5 )

4.5 × tan23° = b , then

b ≈ 1.9 ( to 1 dec. place )

Voltage sags and swells. The power quality of a transformer is measured by the quality of the voltage. Two causes of poor power

zysi [14]

Answer:

$z-score = 1.57$

$z-score_s = -3.36$

Step-by-step explanation:

From the question we are told that

The sample size is n = 103

The sample mean of sag is $\= x_1 = 353$

The sample mean of swells is $\= x_2 = 184$

The standard deviation of sag is $s_1 = 30$

The standard deviation of swells is $s_2 = 25$

The number of swell for a randomly selected transformer is k = 100

The number of sag for a randomly selected transformer is c = 400

Generally the z-score for the number of swells is mathematically represented as

$z-score_s = \frac{ k - \= x_2}{s_2}$

=> $z-score_s = \frac{ 100- 184}{25}$

=> $z-score_s = -3.36$

Generally the z-score for the number of sags is mathematically represented as

$z-score = \frac{ c - \= x_1}{s_1}$

$z-score = \frac{ 400 - 353}{30}$

$z-score = 1.57$

The radius r of a circle is increasing at a rate of 7 centimeters per minute. (a) find the rate of change of the area when r = 1

VikaD [51]

Dr /dt = 7

A = pi r^2

dA / dr = 2pir

dA/dt = dA/dr * dr/dt = 2pir * 7 = 14pir

when r = 12 rate of change of the area = 14*pi*12 = 168pi

= 527.79 cm^2 / minute to nearest hundredth
