Step-by-step explanation:
<span>X^2- 4x- 6y- 14=0
6y = x^2 - 4x - 14
Divide through by 6:-
y = (1/6)x^2 - (2/3)x - 7/3</span>
20, 180 - 20, 180 + 20 and 360 - 20
i.e. 20°, 160°, 200° and 340°
Answer:
Option C (f(x) = 
)
Step-by-step explanation:
In this question, the first step is to write the general form of the quadratic equation, which is f(x) = 
, where a, b, and c are the arbitrary constants. There are certain characteristics of the values of a, b, and c which determine the nature of the function. If a is a positive coefficient (i.e. if a>0), then the quadratic function is a minimizing function. On the other hand, a is negative (i.e. if a<0), then the quadratic function is a maximizing function. Since the latter condition is required, therefore, the first option (f(x) = 
) and the last option (f(x) = 
) are incorrect. The features of the values of b are irrelevant in this question, so that will not be discussed here. The value of c is actually the y-intercept of the quadratic equation. Since the y-intercept is 4, the correct choice for this question will be Option C (f(x) = ). In short, Option C fulfills both the criteria of the function which has a maximum and a y-intercept of 4!!!
Answer:
<h2>$2479.5</h2>
Step-by-step explanation:
In this problem we will estimate her monthly earnings
given that she earns $13.05 per hour
and also given that she works for 190 hours in a month
then in a month, her earnings will be
=$13.05*190
=$2479.5
alternatively,
per week she works 47.5hours
in a week she will earn 13.05*47.7= $622.485
4 weeks make a month
then after one month her earning will be
$622.485*4= $2479.5
