Answer:
a = 360 * 0.27^n
Step-by-step explanation:
a = 360 * (1 - .073)^n
a = 360 * 0.27^n
Answer: x = the quantity of 5 plus or minus the square root of 29 all over 2
Step-by-step explanation:
The given quadratic equation is expressed as
x² - 5x - 1 = 0
The equation is already in the standard form of ax² + bx + c
The general formula for solving quadratic equations is expressed as
x = [- b ± √(b² - 4ac)]/2a
From the given quadratic equation,
a = 1
b = - 5
c = - 1
Therefore,
x = [- - 5 ± √(- 5² - 4 × 1 × - 1)]/2 × 1
x = [5 ± √(25- - 4)]/2
x = [5 ± √29]/ 2
x = ( 5 + √29)/- 2 or x = (5 - √29)/2
Answer:
16.7 Units
Step-by-step explanation:
To find the length of r, you set up the equation as sin(45)= 4.9/r. Then you get r by itself changing it to r = 4.9/sin(45). Then you can find that r = 6.9. Since this is an isosceles triangle, n^1 has to be equal to 4.9. Then you add all the side lengths together. 4.9 + 4.9 + 6.9 = 16.7 units
Answer:
It takes 534.54 watts
Step-by-step explanation:
Given :
Mass of the book = 30kg
Distance = 10m
Time = 5.5 sec
To Find:
How much power did it take = ?
Solution:
Step 1: calculate the work done
Work done = 
where
m = mass
a = acceleration due to gravity
d = distance
Substituting the values,
Work done = 
=> 2940 Nm
Step 2: calculate the Power
We know that
Substituting the values,
Power = 534.54 watts
Answer:
A (Elise needs 7 quarts of ice cream)
Step-by-step explanation:
Okay so we know that Elise is serving 42 people, since she's making 42 chocolate ice cream sundaes.
Since it takes 3 quarts to serve 18 people, we know that the amount of people divided by 6 will equal the quarts.
So 42 people divided by 6 equals 7 quarts.
i hope this helps !!
