Answer:

18

Step-by-step explanation:

Imagine the points on a coordinate plane

3,0 is 3 units above 0,0 and 0,6 is 6 units right of 0,0

since you know 2 sides, you can find the area, 3*6=18

What is the average rate of change in f(x) over the interval [4,13]?
mestny [16]

we know that

Average Rate of Change. is the change in the y-value divided by the change in the x-value for two distinct points on the graph

So

A=\frac{(f(b)-f(a))}{(b-a)}

in this problem

a=4\\ b=13\\ f(a)=f(4)=8\\ f(b)=f(13)=11

substitute the values in the formula above

A=\frac{(11-8)}{(13-4)} \\ \\ A=\frac{3}{9}

Divide by 3 both numerator and denominator

A=\frac{1}{3}

therefore

the answer is

\frac{1}{3}

What is the area of the sail?
marishachu [46]
Area = 30 meters ^2

Area of a triangle is found by multiplying both sides and then dividing that answer by 2.

So 6 times 10 is 60, and 60 divided by 2 is 30.

Please help with my math
shusha [124]

Answer:

Step-by-step explanation:

These triangles are similar triangles, so there is a number that you can multiply the sides of TUV to find the side lengths of QRS. looking at the triangle, the similar sides are RS being similar to UV and RQ being similar to UT.

If RS~UV, then there is a ratio between them. 54/36=1.5. The ratio is 1.5.

RQ~UT, and by a factor of 1.5, so divide RQ by the scale factor. 24/1.5=16. UT=16=x+5.

x+5=16, subtract 5 from both sides.

x=11

prisoha [69]

Answer:

Part A: x0.50 + 3 = 18.50

Part B: x0.75 + 3 - x0.10 = 21

Part C: The equations from Part A and Part B differ because of the cost of plastic cup.

Step-by-step explanation:

Let x represent the number of cup of lemonade sold. Therefore, we have:

Part A:

This situation can be represented by the following equation:

x0.50 + 3 = 18.50

Part B:

This situation can be represented by the following equation:

x0.75 + 3 - x0.10 = 21

Part C:

The equations from Part A and Part B differ because of the cost of plastic cup.

For equation from Part A, revenue is the same as profit as Sydney does incur any cost to buy plastic cup before selling her lemonade.

For equation from Part B, revenue is different from profit because Daria has to incur the cost of plastic cup which $0.10 per cup of lemonade before selling her lemonade.
