A bird drops a stick to the ground from a height of 75 ft. The function h= - 16t2 + 75 gives the stick's
approximate height h above the ground, in feet, after t seconds. Graph the function. At about what time does the stick hit the ground?
graph.
Answers
The function h(t) = -16t^2 + 75 is a quadratic function, and the stick hits the ground at about 2.165 seconds
How to determine the time it hits the ground?The function is given as:
h(t) = -16t^2 + 75
Next, we plot the graph of the function h(t)
From the graph of the function h(t) (see attachment), we have the following highlight:
t = -2.165 and t = 2.165 when h(t) = 0
Time cannot be negative.
So, we have:
t = 2.165
This means that the stick hits the ground at about 2.165 seconds

If the population of Alaska in 2000
was 622,000 and 733,000 in 2020,
assuming exponential growth, what
would the population be in 2050?
[ ? ] people
Answers
The number of people by the year 2050 is obtained as 927915 people.
What is the population in 2050?We know that population is an exponential growth problem in this case. We have to apply the formula;
P = Poe^rt
P = population at time t
Po = Initial population
r = population growth rate
t = time taken
Now;
We have to use the relation to find the growth rate as follows;
733,000 = 622,000 e^20r
733,000/622,000 = e^20r
1.178 = e^20r
ln(1.178) = 20r
r = ln(1.178)/20
r = 0.008
Now;
In the year 2050, we would have;
P = 622,000 e^50 * 0.008
P = 927915 people

Now we have to increase the number 88 by 14%, which means we have to add 14% of 88 (12.32) to the given number (88)
88 + (14% of 88)
= 88 + 12.32

Step-by-step explanation:
Using the Pythagorean Theorem, we know that in a right angle triangle to find the longest side we must use the equation a^2 = b^2 + c^2
A is the longest side while b and c are the other two sides
To find one side we must use
b^2 = a^2 - c^2
a squared = 6.9 squared - 3.5 squared
a^2 = 35.36
square root 35.36 to get a

F = 1.8C + 32
F = 1.8(0) + 32 = 32 Fahrenheit
F = 1.8(30) + 32 = 86 Fahrenheit
F = 1.8(100) + 32 = 212 Fahrenheit
Answer:
C) F = 1.8C + 32
Step-by-step explanation:
Hello! The easiest way to do this is to substitute the numbers from your table into your possible answer choices until you find numbers that make a true/correct statement.
For A:
F = 32C + 1.8 <== substitute any number for F and C from your table
32 = 32(0) + 1.8 <== multiply
32 = 0 + 1.8 <== add
32 = 1.8
This statement is false/incorrect
For B:
C = 1.8F + 32 <== substitute any number for F and C from your table
0 = 1.8(32) + 32 <== multiply
0 = 57.6 + 32
0 = 89.6
This statement is false/incorrect
For C:
F = 1.8C + 32 <== substitute any number for F and C from your table
32 = 1.8(0) + 32 <== multiply
32 = 0 + 32 <== add
32 = 32
This statement is true/correct
For D:
C = 32F + 1.8 <== substitute any number for F and C from your table
0 = 32(32) + 1.8 <== multiply
0 = 1024 + 1.8 <== add
0 = 1025.8
This statement is false/incorrect
As we can see, the only equation that makes a true statement is C.
Therefore, the correct answer is C.
