The graph shows the distance, y in miles, of a moving train from a station for a certain period of time, x, in hours: A graph ti

tled Distance Vs Time is shown with Time in hours labeled on x-axis and Distance from Station in miles labeled on y-axis. The scale on the x-axis shows the numbers 1, 2, 3, 4, 5, 6, 7, and the scale on the y-axis shows the numbers 0, 50, 100, 150, 200, 250, 300, 350, 400. The graph shows a straight line joining the ordered pairs 0, 100, and 1, 150, and 2, 200, and 3, 250, and 4, 300. What is the speed (in miles per hour) of the train?

Mr. Rivera pours 2 cups of blue paint into a jar for each art station. How many jars can
Semmy [17]

Given :

Mr. Rivera pours 2 cups of blue paint into a jar for each art station.

1 cup = 8 ounces.

1 gallon = 128 ounces.

To Find :

How many jars can  he fill with 1 gallon of blue paint.

Solution :

Since, a jar is filled with 2 cups.

1 jar = 2 × 8 = 16 ounces.

So, number of jars required to fill 1 gallon of blue paint is :

n=\dfrac{128}{16}\\\\n=8

Therefore, 8 jars are required to fill 1 gallon of blue paint.

Hence, this is the required solution.

What is the answer, and how do I solve that equation in order to get my answer? I really want to get the hang of this.
Mrrafil [7]

Answer:

-x^2+4x+6

Step-by-step explanation:

f(x) = 4x+1

g(x) = x^2 - 5

(f-g) (x) = 4x+1 - ( x^2 - 5)

Distribute the minus sign

            = 4x+1 - x^2 +5

 Combine like terms

         = -x^2+4x+6

How can you find a trigonometric function of an acute angle 0 ?​
Shkiper50 [21]
The characteristics of similar triangles, originally formulated by Euclid, are the building blocks of trigonometry. Euclid's theorems state if two angles of one triangle have the same measure as two angles of another triangle, then the two triangles are similar. Also, in similar triangles, angle measure and ratios of corresponding sides are preserved. Because all right triangles contain a 90° angle, all right triangles that contain another angle of equal measure must be similar. Therefore, the ratio of the corresponding sides of these triangles must be equal in value. These relationships lead to the trigonometric ratios. Lowercase Greek letters are usually used to name angle measures. It doesn't matter which letter is used, but two that are used quite often are alpha (α) and theta (θ).
