Over what interval does this function remain constant? Do not use any spaces in your interval.
Answer:
We conclude that the function remains constant over the interval [0, 2].
Step-by-step explanation:
We know that if x increases from left to right and y remains constant, the function remains constant over a certain interval.
From the given graph below, it is clear that from x = 0 to x = 2 the value of y does not change.
In other words, the value of y remains constant from x = 0 to x = 2.
i.e.
at x = 0, y = 5
at x = 1, y = 5
at x = 2, y = 5
Therefore, we conclude that the function remains constant over the interval [0, 2].

The difference is
.
Answer:
The answer to the first question is 7.15
The answer to the second question is 1.73
Answer:
7.15; 1.73
Step-by-step explanation:
6.2 is the same as 6.20, so:
6.20
+ 0.95
= 7.15
0.8 is the same as 0.80, so:
2.53
- 0.80
= 1.73

A photographer is 6 feet tall and cast a shadow that is 2 feet long. He is photographing a palm tree with a shadow that is 7 feet long. What is the height of the tree
Answer: The height of the tree is 21 feet.
Step-by-step explanation:
Here we can assume that the angle at which the sun impacts the photographer and the tree to be the same angle.
Then we can think in both cases as triangles rectangles, where the height is a cathetus, and the shadow is the other cathetus.
Then we will have a relationship like:
Tg(angle) = shadow/height
height = shadow/Tg(angle)
Now, because for both triangles we have the same angle, then Tg(angle) will be the same number for both cases, and we can just think of it as constant K
Tg(angle) = K
Then we have the equation:
Height = Shadow/K
We know that the photographer is 6ft tall, and his shadow is 2 ft long, we can replace those two things in the above equation and find the value of k:
6ft = 2ft/K
K = 2ft/6ft = (1/3)
Now we know that the shadow of the tree is 7ft long, then the height will be:
height = 7ft/(1/3) = 7ft*3 = 21ft
The tree is 21 ft tall.
5.) A graph showing a proportional relationship will...
Answer:
C. A straight line that goes through the origin.
Step-by-step explanation:
A graph representing a proportional relationship between variable x and variable y will have a straight line. This straight line must also cut across or pass through the point of origin (0, 0).
Therefore, the answer is: "A straight line that goes through the origin."

A delivery company has 18 vehicles in its fleet.
It has 8 vans and 10 trucks.
All 18 vehicles are on the road every working day.
The company is reviewing its fuel expenses and therefore
gathers some information about each type of vehicle.

same type of fuel at
£1.29 per litre.
Truck

6.2
Use this information to work out the total fuel bill for 1 working day.
You must show all your working.
Answer: £1517.04
Step-by-step explanation:
The fuel expenses for the vans will be calculated as:
Vans:
Since the average distance travelled per day is 198km and the average distance travelled per litre is 9km, the van would use:
= 198/9
= 22 litres
Since there are 8 vans, they'll use:
= 22 × 8 = 176 liters
Trucks:
Since the average distance travelled per day is 620km and the average distance travelled per litre is 6.2km, the truck would use:
= 620/6.2
= 100
Since there are 10 trucks, they'll use:
= 100 × 10 = 1000 liters
The amount of liters for both the van and the truck will be:
= 176 liters + 1000 liters
= 1176 liters
The fuel cost will then be:
= 1176 × 1£1.29
= £1517.04

A bake sale committee wants to raise $175 for a donation to a local charity. They set aside $14 of their profit at the end of each day. How many days will it take them to raise enough money for the whole donation?
Answer:
Number of days= 12.5
Step-by-step explanation:
Giving the following information:
A bake sale committee wants to raise $175 for a donation to a local charity. They set aside $14 of their profit at the end of each day.
To calculate the number of days required to raise $175, we need to use the following formula:
Number of days= total amount / profit per day
Number of days= 175/14
Number of days= 12.5

Grayson is playing a game in which the object is to obtain a 0 by adding the points scored during each round.
Round 1 Round 2 Round 3 Round 4 Round 5
4
7
1
-12
Based on the points he scored during the first 4 rounds, what score does Grayson need on the 5th round?
-24
-11
12
Answer:
0. See explanation below.
Step-by-step explanation:
Grayson is playing a game in which the objective is to obtain a zero, by adding together the points scored in each round.
For rounds 1 to 4,
4 + 7 + 1 + -12 = 12 - 12 = 0
The summation of points in the first four rounds already results to a zero.
Let us see if the addition of any of the three options for round 5 will still result in a zero!
0 + -24 = -24
0 + -11 = -11
0 + 12 = 12
So all the options here are wrong. The only option that would have been correct is 0.
Since 4 + 7 + 1 + -12 + 0 = 0
Maybe the complete question has 0 as the fourth option. Use that.
