Answer:
The answer is below
Step-by-step explanation:
A linear function graph can be represented by:
y = mx + b; where m is the slope and b is the y intercept, x is the independent variable and y is the dependent variable.
a) From the graph we can see the graph passes through the point (0, 100) and (20, 400). Hence we can use the following formula to find the equation:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-100=\frac{400-100}{20-0}(x-0)\\\\y-100=15x\\\\y=15x + 100[/tex]
b) An example of real life linear function is the energy consumed per day in kWh. Let us assume 5 kWh is consumed each day by the person. Since the independent variable is the days, it would be on the x axis, while the dependent variable (energy consumed) would be on the y axis.

In the evening, the temperature is 28 degrees. By midnight it has dropped 31 degrees lower. Between midnight and 4 am it goes down 6 more degrees. Then, by 9 am, the temperature goes up 30 degrees. What is the temperature at 9 am?
Answers
Answer: 21 degrees
Step-by-step explanation:
In the evening, the temperature is 28 degrees and by midnight it has dropped 31 degrees lower, the temperature by midnight will be:
= 28° - 31°
= -3°
Between midnight and 4 am it goes down 6 more degrees. The temperature by 4am will be:
= -3° - 6°
= -9°
Then, by 9 am, the temperature goes up 30 degrees, the temperature at 9 am will then be:
= -9° + 30°
= 21°

Martha was making apple tarts. She added 1/2 cup of sugar in the beginning. Later, she added another 1/4 cup of sugar. Martha estimated that she added about 1/6 cup of sugar in all. Is Martha's estimate reasonable?
Answers
Answer: her answer is NOT reasonable because 1/2 is bigger that 1/6. The real addition to 1/2 and 1/4 is 3/4.
Step-by-step explanation:
1/2 is 2/4 and 1/4 stays the same because it is the common denominator

Item 19 The staircase has three parallelogram-shaped panels that are the same size. The horizontal distance between each panel is 4.25 inches. What is the area of one panel?
Answers
Answer:
[tex]Area = 287\ in^2[/tex]
Step-by-step explanation:
Given
[tex]Length = 20.5[/tex]
[tex]Space = 4.25[/tex]
[tex]Panels = 3[/tex]
See attachment
Required
The area of one panel
From the attachment, the total width is 50.5in.
i.e.
[tex]Total\ Width = 50.5[/tex]
Given that there are 2 spaces between the 3 panels and each space has a length of 4.25 in.
The reduced width is:
[tex]Reduced\ Width = 50.5 - 2 * 4.25[/tex]
[tex]Reduced\ Width = 42[/tex]
At this point, we can calculate the width of one panel by dividing the reduced width by the number of panels (3).
[tex]Width = \frac{42}{3}[/tex]
[tex]Width = 14[/tex]
The area of one is:
[tex]Area = Length * Width[/tex]
[tex]Area = 20.5 * 14[/tex]
[tex]Area = 287\ in^2[/tex]

I = 48
Answer:
the simple interest earned was £48.

the appropriate simple interest formula is i = prt, where r is the annual interest rate as a decimal fraction. Here, with prt = (£800)(0.02)(3 yr), we find that the simple interest earned was £48.
If angle DCA measures 40 degrees, what does angle ACB measure?
Answers
*see attachement for the diagram that is being referred to
Answer:
m<ACB = 50°
Step-by-step explanation:
From the diagram, <DCB is a right angle = 90°
Therefore:
m<DCA + m<ACB = 90° (complementary angles)
m<DCA = 40° (given)
Thus:
40° + m<ACB = 90° (Substitution)
m<ACB = 90° - 40° (Subtraction property of equality)
m<ACB = 50°

5. A cook needs 10 pounds of flour. He wants to spend the least amount of money. A 2-
pound bag costs $1.59 and a 5-pound bag costs $2.89, which should he buy in order to spend
less money? *
Answers
Answer:
He should buy two of the 5-pound bag.
Step-by-step explanation:
The cook needs 10 pounds of flour.
He wants to spend the least amount of money.
First option is a 5-pound bag for $2.89 each.
He can get 2 of the 5-pound bag which equals 10 pounds of flour for 2 x $2.89 = $5.78
Second option is a 2-pound bag for $1.59 each.
He can get 5 of the 2-pound bag which equals 10 pounds of flour for 5 x $1.59 = $7.95.
Second option is $2.17 costlier than the first option.
So, he should go for 2 of the 5-pound bag in order to spend the least amount of money while shopping for 10 pounds of flour.
