Using linear functions, it is found that the number of electronics that you need to sell for a larger income in option A is x > 200,000.
What is a linear function?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.Considering the base salaries as the intercept and the commissions as the slope, the functions are given by:
A(x) = 10000 + 0.09x.B(x) = 20000 + 0.04x.To produce a larger income in option A, it is needed that:
A(x) > B(x).
Hence:
10000 + 0.09x > 20000 + 0.04x
0.05x > 10000
x > 10000/0.05
x > 200,000

Given that 5 cos (x+8.5)° - 1 = 0
0° ≤x≤ 90, calculate correct to the nearest degree, the value of x.
Answer:
x = 70
Step-by-step explanation:
To solve for x, use inverse operations to undo the operations performed on x.
__
5cos(x +8.5)° -1 = 0 . . . . given
5cos(x +8.5)° = 1 . . . . . . add 1
cos(x +8.5)° = 1/5 . . . . . divide by 5
x° +8.5° = arccos(1/5) . . . . take the inverse cosine
x° = arccos(1/5) -8.5° ≈ 70° . . . . evaluate the expression
The value of x is 70.
"solve for the following trig ratios using the unit circle":
1. tan(1755 degrees)
i have no idea how to do this. like do i use estimation orrrr.???
=========================================================
Explanation:
The goal is to get that 1755 degree angle between 0 and 360, so we can refer to the unit circle later.
Subtract off 360 from this until we get to that target
1755 - 360 = 13951395 - 360 = 10351035 - 360 = 675675 - 360 = 315Or a shortcut could be
1755 - 4*360 = 315The angles of 1755 degrees and 315 degrees are coterminal. They point in the same exact direction which is directly southeast in quadrant IV.
Now use the unit circle (see below) to find that
sin(315) = -sqrt(2)/2cos(315) = sqrt(2)/2Dividing those two items and simplifying gets us
tan(315) = sin(315)/cos(315) = -1
Then we go from tan(315) = -1 to tan(1755) = -1

what is the positive solution of x²-36=5×
Answer:
I'm assuming the x at the end is a variable
9, -4
Step-by-step explanation:
If we replace x with 9, we get 81-36=45 which is 45=45 so 9 is one solution.
If we replace x with -4, we get 16-36=-20 which is -20=20 so -4 is the other solution
So, the solutions are 9 and -4.

a regular number cube is rolled. What is the probability that a 3 will not be rolled?
•1/6
•1/2
•4/5
•5/6
Answer:
5/6
Step-by-step explanation:
Answer:
5/6
Step-by-step explanation:
probability(event) = (number of desired outcomes)/(total number of outcomes)
The total number of outcomes is 6 since there are 6 different sides on the cube.
The number of desired outcomes is 6 minus 1 for rolling a 3, so it is 5.
p(not 3) = 5/6

According to the fundamental theorem of algebra.
The polynomial function has only exactly 6 roots.
The roots are the value of the variables in the polynomial at which the value of the polynomial is zero.
If the degree of the variable is n then the number of the roots will be n or less than n.
If the number of the roots are 6, then the degree of the variable will be 6 in the polynomial.

Flying with the wind, a plane flew 1,200 mi in 4 h. Against the wind, the plane required 6 h to fly the same distance. Find the rate of the plane in calm air and the rate of the wind.
Answer:
Rate of plane = 250 mph
Rate of wind = 50 mph
Step-by-step explanation:
Let the speed of the plane in calm air be x mph& speed of the wind be y mphSpeed of plane with wind = (x + y) mphSpeed of plane against wind = (x - y) mphFormula relating speed, time and distance is given as: speed*time = distanceAccording to the first condition: (x+y)*4 = 1200-> x + y = 300 (1)According to the second condition: (x-y)*6= 1200-> x - y = 200 (2)Adding equations (1) & (2), we find:2x = 500-> x = 250 (Dividing 500 by 2)-> y = 50 (Plugging x = 250 in eq 1)Rate of plane = 250 mphRate of wind = 50 mphWrite the equation of the line that passes through the point
(1,−5) and with the slope of −3. Write the in slope-intercept form.
Answer:
y = -3x -2
Step-by-step explanation:
Hi there!!
We're given that a line has a slope of -3 and it contains the point (1, -5)
We want to write the equation of this line in slope-intercept form
Slope-intercept form is given as y=mx+b, where m is the slope and b is the y intercept
As we are already given the slope, we can immediately plug it into the equation.
Replace m with -3 in y=mx+b.
y = -3x + b
Now we need to find b
As the equation passes through the point (1, -5), we can use its values to help solve for b.
Substitute 1 as x and -5 as y:
-5 = -3(1) + b
Multiply
-5 = -3 + b
Add 3 to both sides
-2 = b
Substitute -2 as b into the equation
y = -3x - 2
Hope this helps!
