Answer:
9.17 ft
Step-by-step explanation:
Put x=12 in the equation and evaluate. (The sine argument is in degrees.)
y = 1.5·sin(25.72(12 +1.5)) +9.5 = 1.5·sin(347.22) +9.5
y = -0.33 +9.5 = 9.17
The water will be 9.17 feet deep at noon.
Answer: 40%
Step-by-step explanation: The total number of pizzas is 12 + 18 = 30. Mitchel bought 12 of those 30 pizzas. To find the percentage you do the portion/total. Thus 12/30 = 0.4, as a proportion. To turn a proportion into a percentage simply multiply by 100. 0.4 * 100 = 40%
Answer:

Step-by-step explanation:
Let
we know that
The perpendicular bisector pass through the midpoint of AB
step 1
Find the midpoint AB


step 2
Find the slope of the given line AB
The formula to calculate the slope between two points is equal to
substitute
step 3
Find the slope of the perpendicular bisector
we know that
If two lines are perpendicular, then the product of their slopes is equal to -1

we have
----> slope of the given line
substitute in the formula


step 4
Find the equation of the perpendicular bisector
we know that
The equation of the line into point slope form is equal to

we have


substitute
