Answer:
(f ￮ g)(8) = - 6
Step-by-step explanation:
Evaluate g(8), then substitute the value obtained into f(n)
g(8) = 8 - 2 = 6 , then
f(6) = - 6
Answer:
-62
Step-by-step explanation:
Two functions are given to us , which are ,
[tex]\bf\implies f(n)= -n \\\\\bf\implies g(n)= n - 2 [/tex]
We need to find , ( f • g )(8) . So ,
⇒ ( f • g) = - n ( n - 2 )
⇒ ( f • g) = -n² + 2
⇒ (f • g) = 2 - n²
==================================
Substituting n = 8 :-
⇒ ( f • g)(n) = 2 - n²
⇒ ( f • g)(8) = 2 - 8²
⇒ (f • g)(8) = 2 - 64
⇒ ( f • g)(8) = -62 .
Hence the required answer is (-62) .Meteorologists recorded a temperature change from 72˚F to 28˚F in one day. Write an equation that represents how many degrees the temperature fell.

On a map, an art gallery is located at (13,-3). A car wash is located at(13,-5) . If each unit on the map is a city block, how many city blocks is the art gallery from the museum?
Answer:
The art gallery is 2 city blocks from the car wash
Step-by-step explanation:
If the x-coordinates of two points on a line equal, then the line is a vertical lineThe length of a vertical segment whose endpoints are (x, y1) and (x, y2) is Iy2 - y1ILet us solve the question
∵ The art gallery is located at the point (13, -3)
∴ x1 = 13 and y1 = -3
∵ A car wash is located at (13, -5)
∴ x2 = 13 and y2 = -5
∵ x1 = x2 = 13
→ That means the gallery and the car wash located vertically over each other
∴ The distance between them = Iy2 - y1I
∵ y1 = -3 and y2 = -5
∴ The distance between them = I-5 - (-3)I
∴ The distance between them = I-5 + 3I
∴ The distance between them = I-2I
→ Remember the absolute value cancel the negative sign
∴ The distance between them = 2 units
∵ Each unit on the map is a city block
∵ The distance between them is 2 units
→ That means the vertical distance between them is 2 city blocks
∴ The art gallery is 2 city blocks from the car wash

2. Atmospheric carbon dioxide (CO 2 ) is believed to be a primary factor in global warming Levels of CO, are increasing because human activities, such as burning fossil fuels, send more CO 2 , into the atmosphere than natural biological processes remove Estimates in 2012 suggested that Earth's atmosphere contained 393 parts per million (ppm) of co 2 with another 2 ppm added each year a) Based on findings of the 2012 study, what function could be used to estimate the atmospheric CO 2 at any time x years after 2012 b) Using your model from part a What level of atmospheric CO 2 can be expected in the year 2025? In what year can we expect atmospheric CO 2 to reach 400 ppm? M o nd c Suppose that omissions from
Answer:
(a)Required relation is 393 + 2x ppm
(b)Amount of [tex]CO_2[/tex] concentration in 2025 is 419 ppm
(c)After 3.5 years concentration of [tex]CO_2[/tex] is 400 ppm
Step-by-step explanation:
From the question it is given that :
Estimated [tex]CO_2[/tex] in atmosphere in 2012 is 393 (parts per million)ppm
[tex]CO_2[/tex] level increasing per year is 2 ppm
(a) Let y be the concentration of [tex]CO_2[/tex] in atmosphere after x years from 2012 then:
y = 393 + 2x ppm
Therefore required relation is 393 + 2x ppm
(b) amount of [tex]CO_2[/tex] in 2025 i.e.,x = 13 years after 2012 is y
y = 393 + 2 x 13 = 393+ 26 = 419 ppm
Therefore, amount of [tex]CO_2[/tex] concentration in 2025 is 419 ppm
(c) give y = 400 ppm and x be the year then
400 = 393 + 2x
2x = 7
⇒ x = 3.5 years
Therefore after 3.5 years concentration of [tex]CO_2[/tex] is 400 ppm
Mara put down 7.5% on the purchase of her new home. If she put down $14.175, find the purchase price of the home
Given:
Mara put down 7.5% on the purchase of her new home.
She put down $14.175.
To find:
The purchase price of the home.
Solution:
Let x be the purchase price of the home.
According to the question,
Put down = 7.5% of the purchase price of the home.
[tex]14.175=\dfrac{7.5}{100}\times x[/tex]
[tex]14.175=0.075x[/tex]
Divide both sides by 0.075.
[tex]\dfrac{14.175}{0.075}=x[/tex]
[tex]189=x[/tex]
Therefore, the purchase price of the home is $189.

Answer:
ASA
Step-by-step explanation:
If 2 angles and the included side of one triangle are congruent to 2 angles and the included side of the other triangle, then the triangles are congruent.
The included side is the side between the vertices of the 2 triangles.
Here
∠ S = ∠ W ( 1 angle )
∠ R = ∠ X ( 2 angles )
RS = XW ( side between the 2 angles )
Thus the 2 triangles are congruent by the ASA postulate
The number of gallons used to wash dishes varies directly with the number of loads. If it takes 65 gallons to wash 5 loads. How many gallons would be needed to wash 3 loads?
Answer:
13 gallons
Step-by-step explanation:
Answer:
39 gallons
Step-by-step explanation:
We would use a simple relation here
65 gallons washes 5 loads, then
65/5 gallons will wash one load
13 gallons washes one load
Now, to find 3 loads will be
13 * 3 gallons = 39 gallons

Answer:
DE = 15 cm, AB = 6 cm
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal.
(a)
[tex]\frac{DE}{BC}[/tex] = [tex]\frac{CE}{AC}[/tex] , substitute values
[tex]\frac{DE}{5}[/tex] = [tex]\frac{24}{8}[/tex] = 3 ( multiply both sides by 5 to clear the fraction )
DE = 15 cm
(b)
[tex]\frac{AB}{CD}[/tex] = [tex]\frac{AC}{CE}[/tex] , substitute values
[tex]\frac{AB}{18}[/tex] = [tex]\frac{8}{24}[/tex] ( cross- multiply )
24AB = 144 ( divide both sides by 24 )
AB = 6 cm

Michael giokas car from 150 minutes at a constant speed of 70 miles per hour and then for another 2 hours at a constant speed of 81 miles per hour how far did Michael drive so explain how you got your answer
Step-by-step explanation:
150 minutes = 2.5 hours.
2.5 hours * (70 miles/hr) = 175 miles.
2 hours * (81 miles/hr) = 162 miles
Total distance = 175 + 162 = 337 miles.
Hence Michael drove 337 miles in total.

Fu Haifeng of China set a badminton world record with a smash of 332 kilometers per hour. A kilometer is about 58 mile.What is the speed in miles per hour, to the closest whole number?
Answer:
206 miles/hour
Step-by-step explanation:
1 kilometre per hour = 0.621 mile per hour
332 km/hr to miles per hour
= 332 km/hr × 0.621 miles per hour
= 206.295 miles per hour
Approximately to the nearest whole number
= 206 miles per hour
Badminton world record smash speed in miles is 260.17 mile per hour.
Convert into mile per hour:Given that;
Badminton world record smash = 332 kilometers per hour
1 kilometer per hour = 0.621 mile per hour
Find:
Badminton world record smash speed in miles
Computation:
Badminton world record smash speed in miles = 332 × 0.621
Badminton world record smash speed in miles = 260.17 mile per hour

Step-by-step explanation:
#11) 5x + 6 ≤ 11
5x ≤ 5
x ≤ 1 to graph this you need a solid dot on 1 and shading to the left
#12) 5p+ 4 > 14
5p > 10
p > 2 to graph this you need an open dot on 2 and shading to the right
Answer:
11. 5x + 6 <= 11.
12. 5p + 4 > 14.
Step-by-step explanation:
11. THE GRAPH shows that x <= 1.
So it is 5x + 6 <= 11 because
5x <= 5
x <= 1.
12. THE GRAPH shows that p > 2.
So it is 5p + 4 > 14.
5p + 4 > 14
5p > 10
p > 2.

scientists give two different treatments to people who have the flu and determine if their health improved. The results for the test are in the two-way table.
What percentage of people receiving treatment 1 had improved health?
What percentage of people receiving treatment 2 had improved health?
Answer:
58
Step-by-step explanation:
thank me later
The percentage of people receiving treatment 1 had improved health is 48%. The percentage of people receiving treatment 2 had improved health will be 52%.
What is the percentage?The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that scientists give two different treatments to people who have the flu and determine if their health improved. The results of the test are in the two-way table.
The percentage of people receiving treatment 1 had improved health is calculated as,
Percentage = 23 / ( 23 + 25 )
Percentage = 0.48 x 100 = 48%
The percentage of people receiving treatment 2 had improved health is calculated as,
Percentage = 25 / ( 23 + 25 )
Percentage = 0.52 x 100 = 52%
Therefore, the percentage of people receiving treatment 1 had improved health is 48%. The percentage of people receiving treatment 2 had improved health will be 52%.
