The production cost for a t-shirt printing company is a function of the number of t-shirts that are printed, t. The function tha
uranmaximum [27]

Answer:

Therefore the company have to print either 47 or 12 t-shirt for its production cost to be $40 or less.

Step-by-step explanation:

Given that,

The function that models the production cost is

f(t)=0.1 t^2-6t+100

To find the number of t-shirt, we put f(t)=40 in given function.

∴40= 0.1t²-6t+100

⇒ 0.1t²-6t+100-40=0

⇒0.1 t²- 6t +60=0

⇒t²-60t+600=0

Applying quadratic formula x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}, a=1, b= - 60 and c=600

t=\frac{-(-60)\pm\sqrt{(-60)^2-4.1.600}}{2.1}

  = 47.32,12.67

 ≈47, 12

Therefore the company have to print either 47 or 12 t-shirt for its production cost to be $40 or less.

Komok [63]

Answer:

The required length is 37.68 cm

Step-by-step explanation:

We have given the radius of  which is 3 cm and  \thetawhich is \pi\cdot 4

We will use \pi=3.14

We know the formula for length of arc which is:

length of arc=radius x angle

We will substitute the values given we will get:

length=3(3.14)(4)

length=37.68

Hence, the required length is 37.68 cm
