Answer:
The ratio 
is same for every pair of values.
Step-by-step explanation:
See the given graph.
The graph is a straight line which proves that the Rent in dollars is increasing at a constant rate with respect to time in Days. So, for a fixed change in time in Days, there will be a fixed change in the rent in Dollars.
Therefore, yes the function is proportional and the ratio is same for every pair of values.
Hence, option 1 is correct.
Answer:
A. 13.
Step-by-step explanation:
g(x) = 4x + 1
g(3) = 4 * 3 + 1 = 12 + 1 = 13
A. 13 is your answer.
Hope this helps!
Given:
Confidence level = 90%
mean = 71 beats per minute
standard deviation = 6 beats per minute
margin of error = z * δ / √n
where : δ - population of the standard deviation, n is the sample size ; z is the appropriate z value.
90% confidence level = 1.645 in z-value
margin of error = 1.645 * (6/√80) = 1.645 * (6/8.94) = 1.645 * 0.671 = 1.104
The margin of error is 1.10

The height of the kite above the ground is 58.68 ft
Let x be the height of the kite above Chee's hand.
The height of the kite above Chee's hand, the string and the horizontal distance between Chee and the kite form a right angled triangle with hypotenuse side, the length of the string and opposite side the height of the kite above Chee's hand.
Since we have the angle of elevation from her hand to the kite is 29°, and the length of the string is 100 ft.
From trigonometric ratios, we have
tan29° = x/100
So, x = 100tan29°
x = 100 × 0.5543
x = 55.43 ft.
Since Chee's hand is y = 3.25 ft above the ground, the height of the kite above the ground, L = x + y
= 55.43 ft + 3.25 ft
= 58.68 ft to the nearest hundredth of a foot
So, the height of the kite above the ground is 58.68 ft
