Answer:
the rate of change is 5
Step-by-step explanation:
$90 / 18 cars = $5 per car
$45 / 9 cars = $5 per car
$60 / 12 cars = $5 per car
That means the rate of change is 5 (5/1)
1 meter is 100 centimeters, therefore Alana jumped higher by 32 centimeters.
132-100=32
Trigonometry:
We know that csc x = 1 / sin x and π = 180°;
sin 5π/ 6 = sin 150° = 1/2
csc 2π / 3 = 1 / sin 120° = 1 / √3/2 = 2 / √3
Finally:
4 · 1/2 + 7 · ( 2 / √3 )² = 2 + 7 · 4/3 =
= 2 + 28/3 = 2 + 9 1/3 = 11 1/3
4 : 28 is the same as 4/28
4/28 = 1/7
The answer is C
Answer:
6.3 feet
Step-by-step explanation:
use pythagorean theorem
a² + b² = c²
a² + 3² = 7²
a² + 9 = 49
Subtract 9 from both side
a² = 40
Take the square root of both sides
a = 6.324555320336759
Rounded
a = 6.3
