Answer:
I can't see the picture
Step-by-step explanation:
Answer:
Part a) The temperature at noon was -3°F
Part b) The temperature at 3:00 pm was +2°F
Part c) The temperature at 11:00 pm was -6°F
Step-by-step explanation:
The complete question is
When Leo woke up he saw that the temperature was -8°F. By noon the temperature has increased 5°F. Part a) What was the temperature at noon?
Part b) By 3:00 pm, the temperature increased by another 5 degrees Fahrenheit was the temperature at 3:00 pm positive or negative?
Part c) By 11:00 pm, the temperature had dropped 8°F. Was the
temperature at 11:00 PM positive or negative? Explain.
Part a) we know that
You can use a number line to adds the numbers
-8+5=-3°F
therefore
The temperature at noon was -3°F
Part b) we know that
the temperature increased by another 5 degrees
You can use a number line to adds the numbers
-3+5=+2°F
therefore
The temperature at 3:00 pm was +2°F
Part c) we know that
the temperature had dropped 8°F
You can use a number line to adds the numbers
2-8=-6°F
therefore
The temperature at 11:00 pm was -6°F
Answer:
90 degrees
Step-by-step explanation:
A circle circumscribed over a right triangle is the same as a circle circumscribed over a rectangle built from the extension of the right triangle.
That tells us that the hypotenuse is the diameter of the circle in that case.
Here, we can see a triangle that has the hypotenuse as the diameter of the circumscribed circle. We can infer that the triangle is a right triangle.
Answer:
(A) The rate of change in the price of a bushel of corn in the current year is $7.
(B) The price of a bushel of corn in the current year is $2 more than the price of a bushel of corn in the previous year.
Step-by-step explanation:
The graph for the prices of different numbers of bushels of corn at a store in the current year is shown below.
Part A:
The rate of change in the price of a bushel of corn in the current year based upon the number of bushels is known as the slope of the line.
The formula to compute the slope is:

Consider the ordered pairs: (4, 28) and (10, 70)
Compute the slope of the line as follows:


Thus, the rate of change in the price of a bushel of corn in the current year is $7.
Part B:
The data for the price of bushels in the previous year is as follows:
Number of Bushels Price
2 10
4 20
6 30
8 40
Compute the rate of change in the price of a bushel of corn in the previous year based upon the number of bushels as follows:
Consider the ordered pairs: (2, 10) and (6, 30)


The rate of change in the price of a bushel of corn in the previous year is $5.
Thus, the price of a bushel of corn in the current year is $2 more than the price of a bushel of corn in the previous year.
