Which statement best describes the function represented by the graph?
Answer:
Step-by-step explanation:
You read a graph from left to right, just like you would read words on a page in a book. At the left-most "side" of this graph, we are way up at positive infinity. As we move from left to right, the graph begins to drop in y values. A drop in y values indicates a decreasing graph. So it's decreasing, we have that part. As the graph grows up into y values that increase forever, it will also grow in the x direction to negative infinity. As the graph decreases in y values from left to right, the x values increase into positive infinity. So your choice is the second one: The function is decreasing on the interval (-∞, ∞).
Answer:
It's B
Step-by-step explanation:
A train moves at a constant speed of 8 miles every 6 minutes. How far will the train in 3 minutes, 15 minutes, and 60 minutes.
Answer: If the train moves a constant speed of 8 miles for every 6 minutes then if the time where to be 3 minutes you would have to divided 2 and 8 because the time was split in half you would also have to split the 8 as well. Now if the time was 15 minutes you would have to add more since 6 got 9 more you will have to add 9 more to 8.
6 minutes = 8 miles
3 minutes = 4 miles
15 minutes = 17 miles
Hope this helps you :3.
The train will move 4 miles, 20 miles and 80 miles in 3 minutes, 15 minutes and 60 minutes respectively.
What is multiplication?Multiplication is mathematical arithmetic operation. It is also a process of adding same types of expression to some number of times.
Example - 2 × 3 means 2 is added three times or 3 is added 2 times.
Given, a train moves at a constant speed of 8 miles every 6 minutes.
That means in one minute,
= total number of miles / total time taken
= 8 /6
= 4/3 miles
Now, for 3 minutes means 3 times 4/3
= 3 x 4/3
= 4 miles
For 15 minutes,
= 15 x 4/3
= 20 miles
For 60 minute
= 60 x 4/3
= 80 miles.
Therefore, the train will move 4 miles, 20 miles and 80 miles in 3 minutes, 15 minutes and 60 minutes respectively.

Andrea opened a bank account for her daughter Hannah, with a deposit of $ 1,750 . The account will earn 2% simple interest annually. How many months will it take her to earn interest in the amount of $245 on her deposit?
Answer:
84 months
Step-by-step explanation:
I × 100 = P × R × T
I = interest = $245
P = principal = $1750
R = rate = 2%
T = time(in years) = ??
245 × 100 = 1750 × 2 × T
24500 = 3500T
24500/3500 = T
7 = T
To convert the time to month:
7 × 12 = 84 months
Ying Zyiyu covered the first 300 miles of a trip going at 60 mph and the last hundred going at 40 mph. What was his average speed for the entire trip?
NEED IN 5 MINUTES
Answer:
Average speed is (total distance)/(total time).
To find the total time we need to do some division.
Time for 200 miles=200/50=4 hours.
Time for 100=100/40=5/2 hours.
Total time=13/2 hours. Total distance=200+100=300 miles.
Av speed=300/(13/2)=300×2/13=600/13=46.15 mph approx.

3 m
30 m
Please answer fast thank you
Answer:
1)x=21.33
2)Height of tree is 20 m
Step-by-step explanation:
Question 1
ΔABC ≈ΔADE
Property of similar triangles :Corresponding sides of similar triangles are all in the same proportion
So,[tex]\frac{AB}{AD}=\frac{BC}{DE}\\\frac{AB}{AB+BD}=\frac{BC}{DE}\\\frac{12}{12+6}=\frac{x}{32}\\\frac{12}{18}=\frac{x}{32}\\\frac{12}{18} \times 32 =x\\21.33=x[/tex]
Question 2: Find the height of tree
ΔDEF ≈ΔDHI
Property of similar triangles :Corresponding sides of similar triangles are all in the same proportion
So,[tex]\frac{DE}{DH}=\frac{EF}{HI}\\\frac{3}{30}=\frac{2}{HI}\\HI=\frac{2 \times 30}{3}\\HI=20[/tex]
Hence The height of tree is 30 m
A continental breakfast has a choice of toast, muffin, or a bagel AND a choice of coffee, milk or apple juice. How many possible outcomes are there?
There are an unknown number of possible outcomes. To figure this out all we need to do is multiply the amount of options per category to get the number of possible combinations.
In this case, there are 3 choices of food items and 3 choices of drinks.
Therefore, we need to multiply 3 by 3 to get the combinations.
3 times 3 equals 9
In conclusion, there are 9 possible combinations to be made from the choices presented.

A cylindrical rain barrel with a diameter of 3 feet and a height of 4.5 feet is filled to a height of 2.5 feet. How many more gallons of water can the barrel hold? Round your answer to the nearest whole number ( 1 ft ^3 ≈ 7.5 gal)
Answer:
115Gallons
Step-by-step explanation:
1. Calculate the Volume - Volume of a cylinder is done by this formula, V=π*R^2*H.
3.14x1.5^2x4.5=V
V=31.79ft^3
2. Find the amount of Gallons it can hold total - V=31.79 Now per 1ft^3 its roughly 7.5 gallons. 31.79x7.5=238.44gallons
3. Find the amount occupied by the water currently in the barrel - So we need the middle point so we have something to go off of, now 2.5ft isn't half of 4.5, 2.25 is. So 238.44/2=119.22Gallons. Now 2.5 is 53.4% the difference is 3.4. So we need to take 119.22Gallons*.034=4.05 now add that to the 119.22 and you get 123.27 gallons used
4. How much is left over? - Take 238.44-123.27=115.17 more Gallons that the barrel can hold.
Hope this helped :)

PLEASE HELP AGAIN, SORRY I SUCK AT MATH.
Answer:
C. 24 degrees
Step-by-step explanation:
All triangle must be 180 degrees in total. So you have to add all the known degrees together to find the missing degree.
120+36=156
Then subtract the sum of the known angles from 180 to find the degree of the unknown angle
180-156=24
Answer: C
Step-by-step explanation:
I'll explain why.
The sum of the angles in a triangle must be equal to 180º. We already know 2 of the 3 angles, therefore, we can make an equation to find x.
The sum of the angles (x+36+120) must be equal to 180 (=180)
x+36+120=180
Combine like terms
x+156=180
Subtract 156 to isolate x
x=180-156
x=24

Find the area of the shaded regions. Give your answer as a completely simplified exact value in terms of π (no approximations).
Answer:
The area of the shaded area is 27 [tex]\pi[/tex]
Step-by-step explanation:
The formula for the area of a circle is :[tex]\pi *radius^2[/tex]
To work this out you would first have to work out the area of the circle. You can do this by multiplying [tex]\pi[/tex] by the radius of 6 squared, this gives you 36[tex]\pi[/tex]. However the question is asking for that section of the circle.
To work out the area of the shaded section you will first have to look at the missing angle, as it is 90° . A circle has 360° and so if we divide 360 by 90, this gives us 4. This tells us that [tex]\frac{3}{4}[/tex] of the circle is shaded as [tex]\frac{1}{4}[/tex] is not.
To work out the area of the shaded area you would divide the area of the whole circle which is 36[tex]\pi[/tex] by 4, this gives us 9[tex]\pi[/tex]. This tells us the area of 1 quadrant of the circle.
The next strep is to multiply 9[tex]\pi[/tex] by 3, this gives us 27[tex]\pi[/tex]. This is because now that we know the area of one quadrant we can find the area of the shaded area which covers 3 quadrant of the circle.
1) Multiply [tex]\pi[/tex] by 6 squared.
[tex]\pi *6^2=36\pi[/tex]
2) Divide 360 by 90.
[tex]360/90=4[/tex]
3) Divide 36 [tex]\pi[/tex] by 4.
[tex]36\pi/4=9\pi[/tex]
4) Multiply 9 [tex]\pi[/tex] by 3.
[tex]9\pi*3=27\pi[/tex]
Answer:
27 pi

Probability of landing in the white not the red. Please helpppppppppppp!
Fun, geometry disguised as probability.
That's a pentagon, which we can view as 10 right triangles with legs a and s/2 (half of s) and hypotenuse r. So area of the pentagon is
P = 10 × (1/2) a (s/2) = 10 (1/2) (3.2) (4.7/2) = 37.6
The area of the circle is πr² so the circle area is
C = π (4²) = 50.265482
The white area is the difference, C-P, and the probability we seek is the fraction of the circle that's white, so (C-P)/C.
p = (C-P)/C =1-P/C = 1-37.6/50.265482 = 0.251971
Answer: 0.25
