A. The slope is 3.75 because that’s how much the total cost is increasing by when a drink is being added
B. The y-intercept is 6.25 because that is the total cost when the number of drinks(x) is zero.
C. y=3.75x+6.25

Artyom0805 [142]

Answer:

The trigonometric ratio that I would use to find the distance from the base of the tower to the keys is the tangent; tan (86°) = height / distance.

Step-by-step explanation:

You can draw a right triangle with angle 86°, opposite leg equal to the height (50 meter) and adjacent leg equal to the distance from the base of the tower to the keys: tan (86°) = 50 m / x

=> x = 50 m / tan(86°)

x = 50 m / 14.30 = 0.98 m

What is the number whose 4/5 is 144?​
anyanavicka [17]

Answer:

180

Step-by-step explanation:

Multiply 144 by the reciprocal of \frac{4}{5}, that is

The reciprocal of \frac{4}{5} is \frac{1}{\frac{4}{5} } = \frac{5}{4}, then

\frac{5}{4} × 144 = \frac{5(144)}{4} = 180

What is the magnitude of the resultant vector a and b shown below?
denpristay [2]

Answer: SECOND OPTION.

Step-by-step explanation:

It is important to remember that, by definition, the "Resultant vector " is the vector obtained by adding two or more vectors.

 For this exercise you need to use the formula for calculate the magnitude of the resultant vector obtained by adding the vectors "a" and "b" shown in the picture attached:

c=\sqrt{a^2+b^2}

Where "c" is the magnitude of the resultant vector asked in the exercise.

You need to analyze the graph given in the exercise.

You can identify that:

a=4\\\\b=3

Then the next step, knowing which are "a" and "b", is to substitute values into the formula given at the beginning of this explanation, as following:

c=\sqrt{4^2+3^2}

Finally, evaluating, you get that "c" is:

c=\sqrt{16+9}\\\\c=5
