Temperature changes throughout the hours of a day. Early in the morning, temperature increases slowly. At noon, the temperature rises sharply. During the afternoon, the temperature stays the same for several hours. As night falls, the temperature decreases slightly. Choose the graph that best represents this situation,​

Answers

Final answer:

A line graph would best represent the temperature changes throughout the hours of a day, showing a slow increase in the morning, a sharp rise at noon, a plateau in the afternoon, and a slight decrease at night.

Explanation:

The best graph to represent the temperature changes throughout the hours of a day would be a line graph. The graph should show a slow increase in temperature early in the morning, a sharp rise at noon, a plateau during the afternoon, and a slight decrease as night falls. This pattern follows the circadian rhythm, where temperature rises throughout the waking day, peaks in the afternoon, and falls during sleep.

Katrina drinks 0.5 gallons of water per day which expression shows how to find the number of cups of water she drinks in a week or 16 cups in a gallon

Answers

Answer:

its B for Ed

Step-by-step explanation:
well we know that 1/2 a gallon (or 0.5 gallons) is equal to 8 cups. So one gallon is 16 cups. (keep this in the back of your mind)

Now to find how many cups she drinks in a day, find out how many gallons she drinks in a week.

So 0.5 (7) = 3.5

Now compute to see how many cups are in 3.5 gallons.

Write an equation of a line that is parallel to y=-6x+4 and passes through(2,10).write an equation of line which is perpendicular to y=(-2/3)x-5 and passes through point (6,3).
write the equation of three lines so that the y-intercept of each is -3.

Answers

a)y=-6x+4
Slope and intercept a=-6 b=4
equation for new line:
y=cx+d
If new line is parallel c=a=-6 so
y=-6x+d
We substitude point (2,10)
10=-6*2+d /+12
d=22
so y=-6x+22
b) 
y=-(2)/(3)x-5
a=-2/3
b=-5
new line:
y=ex+f
If line is perpendicular e=-(1)/(a)
so e=(3)/(2)
we can write 
y=(3)/(2)x+f
Substituting point (6,3)
3=(3)/(2)*6+f
f=3-9
f=-6
y=(3)/(2)x-6

There are 1,000 fish in a lake. Each year the population declines by 15%, but afterward, the lake is restocked with 500 aditional fish. Write a recursive rule to find the number of fish in the lake for any year

Answers

We begin with 1,000 fish in a lake.
Each year the population declines to 15%
Then they put back 500 fish in the lake.

The equation: (1000 * .85) +500

Which ordered pair is a solution to the equation: y - 3 = x+2?a) (5,10)
b) (0,0)
c) (7,6)
d) (10,5)

Answers

Let's solve for x.y−3=x+2Step 1: Flip the equation.x+2=y−3

Step 2: Add -2 to both sides.x+2+−2=y−3+−2x=y−5

Answer:

x=y−5
Answer:
d) (10,5)

to check:
(5,10)
x=5
y=10

y-3=x+2
10-3=5+2
