What does f(-1) =_<br> and x=_ ?
lubasha [3.4K]

Answer:

F(-1) = 1

x = 3

Step-by-step explanation:

1) Assume that f(-1) = y1

So that point A (x1 = -1; y1) is a point lying in the graph representing the equation y = f(x)

As it can be seen in the figure, the graph representing that equation crosses point (-1; 1)

=> Point A has y1 = 1

=> f (-1) =1

2) Assume that f(x2) = -2

So that point B (x2; y2 = -2) is a point on the graphy representing the equation y = f(x)

As indicated in the figure, the graph crosses point (3; -2)

=> Point B has x2 = 3

=> When f(x) = -2, x = 3

Solve the triangle.<br><br> a = 10, b = 23, C = 95°
gayaneshka [121]
C² = a² + b² - (2ab * cosC) 
<span>c² = 10² + 23² - (2 * 10 * 23 * cos95) </span>
<span>c² = 100 + 529 - (460 * -.08715) </span>
<span>c² = 629 - (-40.1) </span>
<span>c² = 669.1 </span>
<span>c = 25.87 </span>

<span>(Sin C) / C = (Sin A) / A </span>
<span>(Sin 95) / 25.87 = SinA / 10, Remember 0 < A < 85 </span>
<span>(10 * Sin95) / 25.87 = Sin A </span>
<span>A = arcsin ((10 * sin95) / 25.87) </span>
<span>A = 22.65º </span>

<span>B = 180 - A - C </span>
<span>B = 180 - 95 - 22.65 </span>
<span>B = 62.35º </span>

<span>I hope this helps. Have a good day.</span>

Determine if there was a percent increase or decrease in the number of trench coats sold, and by how much. (Round your answer to
nordsb [41]

The percentage of trench coats sold increased by 23. 3%. therefore, option D is correct.

<h3>What is the percentage?</h3>

A percentage is a minimum number or ratio that is measured by a fraction of 100.

First, we need to subtract the final from the initial, then divide the difference by the initial, then multiply your answer by 100 to get the percentage

the final is 127, and the initial is 103

127 - 103 = 24

24/103 = 0.233

0.233 x 100

= 23.3%

Thus, The percentage of trench coats sold increased by 23. 3%.
