A taxi company charges $4.50 plus $1.00 for every mile driven. This is given by the function y=x+4.5. You hail a cab and travel

frozen [14]

Fix charge for taxi hiring = $4.50

Variable charge = $1.00 per mile driven.

For the given situation the function woild be y = x+4.5.

Where x represents, number of miles travelled and y represents total cost of a ride.

Total number of miles travelled = 12 miles.

So, we need to plug x=12 in the given fuction to find the total cost of the ride.

Plugging x=12 in given function, we get

y=x+4.5 = 12*1+4.5 = 12+4.5 = 16.50.

Therefore, total cost of 12 miles of ride = $16.50.

We are given a linear function y= x+12.

A linear function as domain and range all real numbers, because we can take any real for x and get some different real numbers for y on plugging in a linear function.

But for the given situation, x is taken by number of mile.

Number of miles could be taken as any real number greater than 0.

And we get some value for y, that would be greater than $4.5.

So, domain would be all real numbers greater than 0. In interval notation, we can write (0, ∞).

Similiarly, range would be all real numbers greater than 4.50. In interval notation, we can write (4.50, ∞).

Choose the correct simplification of the expression (b^5)^4

emmainna [20.7K]

Answer: $b^{20}$

Using the power of a power rule, you would multiply both exponents, 5x4, which equals 20, and you keep the base as is. This leaves you with $b^{20}$ .

hope that helps ✨

What is the value of x in this triangle?

alexira [117]

Answer: $x=14.04\°$

Step-by-step explanation:

Given the right triangle of the figure, you can calculate the measure of the angle represented with "x", by using arcotangent (which is the inverse function of the tangent of an angle).

Then:

$\alpha=arctan(\frac{opposite}{adjacent})$

Substitute the opposite side and the adjacent side of the triangle in the figure.

Therefore, the measure of the angle "x" to the nearest hundreth is:

$x=arctan(\frac{5}{20})\\x=14.04\°$

a recipe calls for 3 1/2 teaspoons of mustard seeds, 4 cups of tomato sauce, and 6 3/4 cups of beans, you use 2 2/3 cups of toma

Ksivusya [100]

Answer:

For a recipe call,

Number of teaspoons of mustard seeds =

Number of cups of tomato sauce = 4

Number of cups of beans =

For 4 cups of tomato sauce, the number of teaspoons of mustard seeds needed =

For 1 cup of tomato sauce, the number of teaspoons of mustard seeds needed =

For cups of tomato sauce, the number of teaspoons of mustard seeds needed =

Hence, for cups of tomato sauce, the number of teaspoons of mustard seeds needed is .

For 4 cups of tomato sauce, the number of cups of beans needed =

For 1 cup of tomato sauce, the number of cups of beans needed =

For cups of tomato sauce, the number of cups of beans needed =

Hence, for cups of tomato sauce, the number of cups of beans needed is .
