Answer:
Step-by-step explanation:
-12 = 12 ....this is incorrect...meaning no solutions
**
if it ended in :
x = a number, or y = a number...means there is 1 solution
if it ended in :
-12 = 12....incorrect answer, means there is no solutions
if it ended in :
2 = 2 or -4 = -4....correct answer, but not variable...means infinite solutions
Answer:
442554 square miles
Step-by-step explanation:
The area of a triangle is given by :
0.5*A*B*Sin(∅) where A and B are two sides and ∅ is the angle between them.
We will find ∅ by applying cosine rule:
c^2 = a^2 + b^2 − 2ab cos(∅)
Where ∅ is angle between sides a and b.
In this example:
a=1028, b=1046, c= 965
Plugging in the values, we get ∅=55.4°
Applying the formula for Area:
0.5*A*B*Sin(∅)
0.5*1028*1046*Sin(55.4)= 442554 square miles
Commision equals percentage times the amount of money bought for the car. It will be 1.5% (0.015) * 22500. The answer is $337.50.
The answer to this is 7/16 * 8= 7/2= 3.5
The linear function in slope-intercept form for the cost of a visit of x hours is given as follows:
C(x) = 9x + 31.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
In this problem, the rate means that the slope is of m = 9. When x = 3, C(x) = 58, hence the y-intercept is found as follows:
C(x) = 9x + b
58 = 9(3) + b
b = 31.
Hence the equation is:
C(x) = 9x + 31.
