Using the graph below, find the value(s) of x for which f(x) = 5.
Answer:
We conclude that:
f(x) = 5 for x = -7, -6, -5, -4, -3, -2, -1, 0 and 2.
Step-by-step explanation:
From the diagram, it is clear that:
There are two parts of the graph:
LEFT GRAPHRIGHT GRAPHLEFT GRAPH
On the left side, the graph of the function indicates that the value of y remains 5 for the values x = -7, -6, -5, -4, -3, -2, -1, and 0.
In other words,
f(x) = 5, for x = -7, -6, -5, -4, -3, -2, -1, and 0.
RIGHT GRAPH
On the right side, the graph of the function indicates that the value of y is 5 at x = 2
In other words,
f(x) = 5, for x = 2.
Therefore, we conclude that:
f(x) = 5 for x = -7, -6, -5, -4, -3, -2, -1, 0 and 2.
At the end of 2005, this price was `\$513.` At the end of 2015, it was `\$1060.` By what percentage did the price per ounce of gold increase?
Answer: The price per ounce of gold increases by 106.63%.
Step-by-step explanation:
Given: Price in 2005 = $ 513
Price in 2015 - $ 1060
Now , [tex]\text{Percentage increase in price}=\dfrac{\text{Change in price}}{\text{ Initial price}}\times100[/tex]
[tex]\Rightarrow\ \text{Percentage increase in price}=\dfrac{1060-513}{513}\times100\\\\=\dfrac{547}{513}\times100\\\\= 1.0663\times100\%=106.63\%[/tex]
hence, the price per ounce of gold increases by 106.63%.

Marilu invested $3,000 in a fund with an interest rate of 2.5% compounded semi-
annually. After 5 years what will the investment be worth?
A = P(1+)
$3,396.81
$9,633.10
$3,380.90
$3,518.18
$4,410.05
Answer:
$ 3,396.81
Step-by-step explanation:
The formula uses to calculate the amount of an investment after t years which is compounded is given as:
A = P(1 + r/n)^nt
Where:
A = Amount of Investment after t years
P = Principal = $3,000
r = Interest rate = 2.5 %
t = Number of years of Investment = 5 years
n = Compounding frequency = semi annually = 2
First, convert R percent to r a decimal
r = R/100
r = 2.5%/100
r = 0.025 per year,
Then, solve our equation for A
A = P(1 + r/n)^nt
A = 3,000.00(1 + 0.0125/2)^(2×5)
A = $ 3,396.81
The total Investment from compound interest on an original principal of $3,000.00 at a rate of 2.5% per year compounded 2 times per year over 5 years is $ 3,396.81.

Tony runs to keep fit. He wants to run a total of 20 km each week. Here are the
distances Tony ran last week.
6.25 km
4 km 750 m
872 km
Did Tony run 20 km last week? You must show how you got your answer.
Answer:
Tony run 19.5 km last week, so he must have run 0.5 km more, to complete 20km run last week.
Step-by-step explanation:
Distance Tony ran last week are
6.25 km
4 km 750 m
872 km (Note: This would be 8 [tex]\frac{1}{2}[/tex] km and not 872 km)
We will add all the distances to check if they sum up to 20km or not.
First we will convert 4 km 750 m into km
We know that 1000 m = 1 km
So, 1 m = 1/1000 km
750 m = 750/1000 = 0.75 km
Now 4km + 0.75 km = 4.75 km
So, 4 km 750 m = 4.75 km
and 8 [tex]\frac{1}{2}[/tex] km = 8.5 km
Now, finding Distance covered by Tony during last week = 6.25 km + 4.75 km + 8.5 km
= 19.5 km
So, Tony run 19.5 km last week, so he must have run 0.5 km more, to complete 20km run last week.

The additive inverse of the polynomial 7x-20 is -7x+20.
The given algebraic expression is 7x-20.
What is additive inverse?The additive inverse of a number is its opposite number. If a number is added to its additive inverse, the sum of both the numbers becomes zero. The simple rule is to change the positive number to a negative number and vice versa.
Here, the additive inverse of given polynomial is
-7x+20
Therefore, the additive inverse of the polynomial 7x-20 is -7x+20.

A florist wants to determine if a new additive would extend the life of cut flowers longer than the original additive. The florist randomly selects 20 carnations from the ones recently delivered by the greenhouse and places the first 10 in water with the new additive and remaining 10 in water with the original additive. After three weeks, 6 carnations placed in the new additive still looked healthy and 2 carnations placed in the original additive still looked healthy. The proportion of healthy carnations with the new additive was significantly greater than the proportion of healthy carnations with the original additive.
Which of the following is a valid conclusion?
Conclusions about cause and effect for the additives can be made, because the florist randomly selected the 20 carnations; additionally, inferences can be made about the population of carnations at the greenhouse.
Conclusions about cause and effect for the additives cannot be made, because the florist did not randomly assign the 20 carnations; however, inferences can be made about the population of carnations at the greenhouse, because the sample was random.
Conclusions about cause and effect for the additives can be made, because the florist took a random sample of 20 carnations; however, inferences cannot be made about the population of carnations at the greenhouse, because the carnations were not randomly assigned to the treatments.

Paige was planting a garden. She planted 1/3 of her garden with roses, 3/6 of her garden with daisies and the rest of the garden with tulips. What fraction of the garden was tulips?
Answer:
1/6
Step-by-step explanation:
Let the total number of flowers planted be 1
Given
Number of roses = 1/3
Fraction of daises = 3/6
Required
Fraction of tullips
Fraction of tullips = 1-(1/3+3/6)
Fraction of tullips = 1-(2+3/6)
Fraction of tullips = 1-5/6
Fraction of tullips = 1/6
Hence the fraction of tulip left is 1/6

Answer:
F. (-4, oo)
Step-by-step explanation:
Start from the left side.
The arrow on the left side shows that the graph continues increasing forever as x decreases. Beginning at the highest value of y you see on the left side at point (-6, 5), as x increases, moving right along the x-axis, the y-values decrease. When you get to x = -4, y is at its lowest value which is 1.
Starting just to the right of x = -4, the y-values begin to increase from the lowest y-value of 1. The arrowhead at the right side top shows that the curve continues increasing forever to infinity.
The values of x for which y increases are all values greater than -4 and all the way to positive infinity.
This function is increasing for x > -4.
Now we need to write x > -4 in interval notation.
In interval notation, use a curved parenthesis to mean a number that is not included. The interval starts at -4, so it starts as
(-4
Then you write a comma to separate from the value where the interval ends.
(-4,
The interval in x of increasing values goes to positive infinity, so now you write the infinity symbol, and you close the interval with a curved parenthesis. By convention, infinity always gets a curved parenthesis. Also, I'll use oo for infinity below.
(-4, oo)
Answer: F. (-4, oo)
