Answer:

1. c = 13

2. a = 20

Step-by-step explanation:

1. 12² + 5² = x²

144 + 25 = x

144 + 25 = 169

√169 = 13

2. 29² - 21² = x²

841 - 441 = x

841 - 441 = 400

√400 = 20

The mean distance of the earth from the sun is 93 million ml The distance varies by 1.6 million ml. What are the maximum and min

drek231 [11]

Answer:

Maximum distance = 94.6 million miles

Minimum distance = 91.4 million miles

Step-by-step explanation:

The mean distance of the Earth from the sun is 93 million miles.

The distance varies by 1.6 million miles.

The maximum distance of the Earth from the sun is 93 + 1.6 = 94.6 million miles

The minimum distance of the Earth from the sun is 93 - 1.6 = 91.4 million miles.

Jerald jumped from a bungee tower. If the equation that models his height, in feet, is h = –16t2 + 729, where t is the time in s

Snezhnost [94]

Answer. First option: t > 6.25

Solution:

Height (in feet): h=-16t^2+729

For which interval of time is h less than 104 feet above the ground?

h < 104

Replacing h for -16t^2+729

-16t^2+729 < 104

Solving for h: Subtracting 729 both sides of the inequality:

-16t^2+729-729 < 104-729

-16t^2 < -625

Multiplying the inequality by -1:

(-1)(-16t^2 < -625)

16t^2 > 625

Dividing both sides of the inequality by 16:

16t^2/16 > 625/16

t^2 > 39.0625

Replacing t^2 by [ Absolute value (t) ]^2:

[ Absolute value (t) ]^2 > 39.0625

Square root both sides of the inequality:

sqrt { [ Absolute value (t) ]^2 } > sqrt (39.0625)

Absolute value (t) > 6.25

t < -6.25 or t > 6.25, but t can not be negative, then the solution is:

t > 6.25
