<h3>Answer:  approximately 6.3 miles</h3>

=================================================

Explanation:

See the diagram below. The two given angles B = 105 and C = 20 are used to help find angle A

A+B+C = 180

A+105+20 = 180

A+125 = 180

A = 180-125

A = 55

Then we use the law of sines to find the side length c

sin(A)/a = sin(C)/c

sin(55)/15 = sin(20)/c

c*sin(55) = 15*sin(20) ... cross multiply

c = 15*sin(20)/sin(55)  .... divided both sides by sin(55)

c = 6.26294249724791 .... value is approximate

c = 6.3 ....... rounding to one decimal place

The table of values represents a function ​f(x).
NeX [460]

Answer:

The average rate of change over the interval [9,10] is greater than that over the interval [5,8] by 6490.

Step-by-step explanation:

The value of f(x) = 4052 for x = 9 and f(x) = 11014 for x = 10.

Therefore, the average rate of change of f(x) with respect to x over the interval [9,10] is given by  

= \frac{\textrm {Total change in value of f(x)}}{\textrm {Total change in value of x}}

= \frac{11014 - 4052}{10 - 9} = 6962

Now, the value of f(x) = 75 for x = 5 and f(x) = 1491 for x = 8.

Therefore, the average rate of change of f(x) with respect to x over the interval [5,8] is given by

= \frac{\textrm {Total change in value of f(x)}}{\textrm {Total change in value of x}}

= \frac{1491 - 75}{8 - 5} = 472

Therefore, the average rate of change over the interval [9,10] is greater than that over the interval [5,8] by (6962 - 472) = 6490. (Answer)

A baker purchased 12 lb of wheat flour and 15 lb of rye flour for a total cost of $18.30. A second purchase at the same prices,
vivado [14]
12w+15r=18.30 /*2
15w+10r=16.75 /*3

24w+30r=36.60, subtract this equation from the other one
45w+30r=50.25

21w=13.65
w=13.65/21
w=0.65 is a cost per pound for wheat flour

From the first equation we have
r=(18.30-12w)/15
r=(18.30-12*0.65)/15
r=0.70 is a cost per pound for rye flour

Which of the following best describes how muckrakers brought about reform in the Progressive Era?
lora16 [44]

Answer:

B

Step-by-step explanation:

Both A and B are similar but the difference is that muckrakers did not present facts to encourage more investigation, they presented facts to make a change. There are many examples but one major one is Upton Sinclair and his book "The Jungle". It exposed the meat industry and how corrupted it was. This led to many changes such as new food safety laws.
