1. The emblem on a college banner consists of the face of a tiger
inside a right triangle. The lengths of two sides of the triangle are
13 centimeters and 14 cm.
What is the length of the longest side of the right triangle?

Answers


1. For a triangle to be a right triangle, it must satisfy the Pythagorean theorem: ; the square of the longest side (hypotenuse) of the triangle is equal to the sum of the squares of its shorter sides.
We know from our problem that the longest side of our triangle is 15 cm long and the shorter sides are 13 cm and 14 cm respectively, so:





We can conclude that the triangle is NOT a right triangle.

2. Just as before, for a triangle to be a right triangle, it must satisfy the Pythagorean theorem: ; the square of the longest side (hypotenuse) of the triangle is equal to the sum of the squares of its shorter sides.
We know from our triangle that its longest side is 8 ft long and its shorter sides are 4,8 ft and 6.4 ft, so lets use the Pythagorean theorem:

The stem-and-leaf plot shows mandy’s math test scores. What is the median of her test score?
A- 88
B- 87
C- 85
D- 84

Answers

Answer: C

Step-by-step explanation:

All the numbers are 78, 80, 83, 84, 84, 86, 89, 91, 95, 100. That’s because for each row, you take the number in the first column, and create each score by putting one of the numbers in the second column next to the first number. The median is the number in the middle if you were to put them out in order. I already listed the numbers in order, and the middle numbers are 84 and 86, so the find the middle of those, you add them together and divide by 2. You get 85, a.k.a. option C.

The topology taxi company charges 2.60 for the first quarter of a mile and 0.36 for each additional fifth of a mile. Find a linear function which models the taxi fare F as a function of the number of miles driven m

Answers

Answer:

The piecewise function for the taxi fare is:

[tex]F(t) = 2.60\cdot \left(\frac {m}{0.25}\right) ,\, 0\,mi\le m \le 0.25\,mi[/tex]

[tex]F(t) = 2.60 + 0.36\cdot \left(\frac{m}{0.2} \right)[/tex], [tex]m > 0.25\,mi[/tex]

Step-by-step explanation:

We must use the following piecewise function:

(i) The Topology Taxi Company charges 2.60 for the first quarter of a mile:

[tex]F(t) = 2.60\cdot \left(\frac {m}{0.25}\right) ,\, 0\,mi\le m \le 0.25\,mi[/tex] (1)

Where:

[tex]F(t)[/tex] - Taxi fare, in monetary units.

[tex]m[/tex] - Number of miles driven, in miles.

(ii) And 0.36 for each additional fifth of a mile:

[tex]F(t) = 2.60 + 0.36\cdot \left(\frac{m}{0.2} \right)[/tex], [tex]m > 0.25\,mi[/tex] (2)

Evaluate f(x) = 2|x – 5| for f(–5) and f(0).

f(–5) = –20, f(0) = –2

f(–5) = 10, f(0) = 0

f(–5) = 20, f(0) = 10

f(–5) = 12, f(0) = 5

Answers

Answer:

f(–5) = 20, f(0) = 10

Step-by-step explanation:

f(-5):

f(-5) = 2|-5 -5|

f(-5) = 2|-10|

f(-5) = 2(10)

f(-5) = 20

f(0):

f(0) = 2|0 - 5|

f(0) = 2|-5|

f(0) = 2(5)

f(0) = 10
