1. Jim is tracking the progress of his plant’s growth. Today the plant is 8cm high. The plant grows 3.5cm per day. What will the height of the plant be on day 28? (Hint: “today” is day 0).
"The plant grows 3.5 cm per day" means that the function grows by 3.5 cm each day. We can make a function like this:
y = 8 + 3.5x
Day 0 -> Day 28 is +28 days, so plug-in x with 28 to find out how much it would have grown in 28 days PLUS the original height of the plant, 8 cm.
y = 8 + 3.5(28) <-- see how I replaced x with 28
Simplify
y = 8 + 98 = 106 cm at day 28
2. The average inflation rate of the U.S. dollar over the last six years is 2.8% per year. If a new car cost $29,000 six years ago, how much would it cost today?
2015, 2016, 2017, 2018, 2019, 2020, 2021
Just to help you imagine the years, we need to find the car's value from $29,000 in 2015 to 2021 using the idea that the car's value increases by 2.8 percent. What does 2.8 percent mean and how do we use this information to find out how much it increases? We need to convert this to a decimal so we can multiply it by 29,000 easily. First, convert 2.8% to a decimal = 0.028. Then we have to add 1 to 0.028. Why? Because we need to make sure that we still have the original 100% of the 29,000. If we forget the 1 then we're just finding 2.8% of 29,000! So, now we know that our multiplier by each year is 1.028. Now we have to multiply.
29,000 x (1.028)^6 (we have a power of 6 because remember, we are multiplying the 1.028 every year, and there are 6 years!)
Simplify: 34,226.0425 that rounds to 34,226.0425 dollars
3. The population of Mickey Village is 48,000 today. Every other year the population increases by 1,550 people. In approximately how many years will the population exceed 70,000 people?

Answer:
(4,0)
Step-by-step explanation:
The x intercept is where the line in the function crosses the x axis or the horizontal line
in here we can see that the line crosses the x intercept 4 "lines" from the origin so we can say the origin is (4,0)
Remember when doing points ( #,#) the first number is the x position which in this scenario is 4 and the second number is the y position and in this case it's 0

If P = (3, 1) and Q = (-3, -7), find The distance PO
Answer:
10 units
Step-by-step explanation:
Given data
P = (3, 1) and Q = (-3, -7)
x1=3
y1=1
x2= -3
y2= -7
The expression for the distance between two coordinate is
d=√((x_2-x_1)²+(y_2-y_1)²)
Substitute
d=√((-3-3)²+(-7-1)²)
d=√((-6)²+(-8)²)
d=√36+64
d=√100
d=10 units
Hence the distance is 10 units

a clock chimes every 20mins
a light flashes every 8 mins
the clock chimes and the light flashes together at 8:00
how many times between 8:01 and 12:30 will the clock chime and the light flash together?
show your working (5marks)
Answer: 6 times
Step-by-step explanation:
it is a lowest common multiple question. So we list the multiples
20 8
40 16
60 24
80 32
40
40 is our lowest common multiple. Which means every 40 minutes they flash and chime together.
so if we add 40 minutes onto 08:00 we get 08:40 and if we add it again we get 09:20 and again we get 10:00 and again we get 10:40 and again we get 11:20 and again we get 12:00. We have to stop here as if we add 40 minutes again we will go over the given time of 12:30. If we count how many times it was added. this adds to 6. therefore the answer is 6.
hope this helped.

For males in a certain town, the systolic blood pressure is normally distributed with a
mean of 120 and a standard deviation of 8. What is the probability that a randomly
selected male's systolic blood pressure will be less than 108, to the nearest
thousandth?
Answer:
0.89
Step-by-step explanation:
The probability that a randomly selected male's systolic blood pressure will be less than 108 is 0.25.
What is Probability?
Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
Here, mean = 110, standard deviation = 8
P = [tex]\frac{x_{mean}-x }{SD}[/tex]
P = (110 - 108)/8
P = 2/8 = 0.25
P(Z<0.25) = 0.5 - 0.25 = 0.25
Thus, The probability that a randomly selected male's systolic blood pressure will be less than 108 is 0.25.

Step-by-step explanation:
Complete question
Choose the equation below that represents the line passing through the point (2, -4) with a slope of 3
The standard equation of a line in point-slope form is y-y0 = m(x-x0)
Given
x0 = 2
y0 = -4
alope m = 3
Substitute
y - (-4) = 3(x - 2)
y + 4 = 3(x - 2)
y + 4 = 3x - 6
y - 3x = -6 - 4
y - 3x = -10
Hence the required equation is y - 3x = -10

Answer:
Median: 9
Range: 4
mode: 9, 8, 11 (each appeared 2 times)
mean: 9.125 (average)
Step-by-step explanation:
solve y=f(x) for x then find the input when the output is 6
f(x)= 6x^2
x = 1
So to figure this out we can readjust the equation to make it easier to solve
[tex]f(x) = 6x^2[/tex] is equal to [tex]6x^2 = 6[/tex]
From here we can simplify to get our answer!
[tex](6 / 6)x^2 = (6 / 6)\\x^2 = 1\\x = \sqrt{1}\\x = 1[/tex]
