Answer:
Step-by-step explanation:
This triangle is a 30°-60°-90° triangle, so you should always remember the rule shown in the picture. Because y is across from the 60° angle, it will be 
. 3 is x because it is across from the 30° angle, so y will be .
Answer:
Solving the expression 
we get: 
Step-by-step explanation:
We need to solve the expression:
This is a quadratic expression and it can be solved using quadratic formula
Solving:
we can write it as:
The quadratic formula is: 
where a = 3, b = -2 and c= 1
Putting values and solving:
So, solving the expression we get:
Answer:
-2
Step-by-step explanation:
The line has a "rise" of -2 units for a 1-unit "run" to the right. (You can see this by counting grid squares.)
The slope is rise/run = -2/1 = -2.
Answer:
546,397 people
Step-by-step explanation:
We solve for the above question, using the formula for Exponential growth
The formula is given as
P(t) = Po (1 + r)^t
Po = Initial population = 310,000
r = Exponential growth rate = 6.5% = 0.065
t = Time in years = 9
P(t) = Population size after time t
Hence:
P(t) = 310,000 × (1 + 0.065)⁹
P(t) = 546,396.82088 people
Approximately =546,397 people
The population will be 546,397 people after 9 years.
Answer:
The percentage increase in Tessa's stock is 40%
Step-by-step explanation:
Given that:
Previous worth = $173
Worth now = $242.20
We have to find percentage increase which can be known by subtracting previous worth from present worth and multiplying it by 100:
Percentage increase = $242.20 - $173 = $69.2
Percentage increase = $69.2/173 *100
Percentage increase = 40%
