kolezko [41]

Answer:

-7 degrees

Step-by-step explanation:

Dropping 12 degrees means that it will get colder by 12 degrees. The colder it gets, the lower the temperature. 5 degrees - the current temperature, is going to be dropped by 12 degrees. To calculate this: 5-12 = -7 (degrees)

Use the information in the diagram to determine the height of the tree to the nearest foot.
algol13

Answer:

The correct option is A. The height of tree is 60 ft.

Step-by-step explanation:

From the given figure it is noticed that the building is creating a right angle triangle from a point and the tree divides the hypotenuse and base in two equal part.

According to midpoint theorem of triangle: In a triangle, if a line segment connecting the midpoints of two sides, then the line is parallel to third side. The length of line segment is half of the length of third side.

Using midpoint theorem of triangle, we can say that the length of tree is half of the building.

Tree=\frac{1}{2}\times Building

Tree=\frac{1}{2}\times 120

Tree=60

Therefore correct option is A. The height of tree is 60 ft.

Andrew is hiking in a mountainous area of a state park. Use the given key features to sketch a graph.
Molodets [167]

Using the features, a piece-wise function is defined, and the graph is sketched at the end of this answer.

A piece-wise function is a function that has <u>multiple definitions</u>, depending on the value of the input.

He starts at 0 feet, and reaches a maximum elevation of 800 feet in 30 minutes, with a steady(linear) increase thus, for the first 30 minutes, the definition is:

h(t) = \frac{800}{30}t, 0 \leq t < 30

For the next 5 minutes, he stops to rest, at the maximum elevation of 800 feet, thus, the definition is:

h(t) = 800, 30 \leq t < 35

For the final 20 minutes, he descends 800 meters, at a linear rate, thus:

h(t) = 800 -\frac{800(t-35)}{20} = 800 - 40(t - 35), 35 \leq t \leq 55

Using these definitions, the graph is sketched at the end of this answer.
