The supplement of an angle is 3 times the complement of an angle.

Let’s says that x is the measure of the angle. X and it’s supplement are equal to 180. X and it’s complement are equal to 90. The supplement is s and the complement is c. S is times c which is the same as 3c.

3c + x = 180

C+x = 90
X = 90 - c

3c + 90 - c = 180
2c = 90
C = 45

The complement of. 45 degree angle is 45 degrees.

The angle is 45 degrees.

What is the multiple zero and multiplicity of f(x)=x^3-14x^2+49x
Stella [2.4K]
X^3 - 14x^2 + 49x = 0

Factor an x out:

x(x^2 - 14x + 49) = 0

Find two factors of 49 that add to -14 (-7 and -7). Convert the trinomial to two binomials:

x(x - 7)(x - 7) = 0

The zeros are:

x = 0 and x = 7.

7 occurs as a zero twice and therefore has a multiplicity of 2.

​Aki's Bicycle Designs has determined that when x hundred bicycles are​ built, the average cost per bicycle is given by​ C(x)=0.
Semmy [17]

Answer:

<u>maximum of 2 bicycle</u>

Step-by-step explanation:

Given the average cost per bicycle modeled by the equation

C(x) = 0.5x^2-1.5x+4.83

C(x) is in hundreds of dollars

x is number of bicycle

The number of bicycle that will minimize the cost occurs when dC/dx = 0

dC/dx = 2(0.5)x - 1.5

dC/dx = x - 1.5

Since dC/dx = 0

0 = x - 1.5

x = 0+1.5x = 1.5

Hence the shop should  buy <u>maximum of 2 bicycle</u> to minimize the cost
