love history [14]3 years ago
6 0

Answer:

20°

Step-by-step explanation:

\because \: l =  \frac{ \theta}{360 \degree}  \times c \\  \\  \therefore \:  \frac{1}{3}  =  \frac{ \theta}{360 \degree}  \times 6 \\  \\  \therefore \:  \theta =  \frac{360 \degree}{3 \times 6}  \\  \\  \therefore \:  \theta =  \frac{360 \degree}{18}  \\  \\ \therefore \:  \huge \red{ \boxed{ \theta = 20 \degree}} \\

F(x) = sqrt(- 2x) Determine for each value whether it is in the domain of f or not.
Gnoma [55]

Answer:

only -2 is in the domain

Step-by-step explanation:

For negative values under the sqrt, there is no real answer, hence

-2x ≥ 0

only for x=-2 this is the case.

The domain represents all the valid input values for x.

Jerome spent $20 on supplies to make 50 cookies for a bake sale. Write and solve an inequality to find the price that Jerome sho
Semenov [28]

Answer:

Each cookie will have to be sold for at least $0.90 if the profit is to be made is more than $25.

Step-by-step explanation:

The amount spent on supplies is $20.

The number of cookies baked is = 50.

If the profit to be made is more than $25.00 .

Then we can safely say that all the cookies have to be sold for

= $20.00 + $25.00

= $45.00

Therefor the required inequality can be written as

50 x ≥ $45.00            ⇒       x   ≥   \frac{45.00}{50}            ⇒      x   ≥  $0.90.

Therefore we can say that each cookie will have to be sold for at least $0.90 if the profit is to be made is more than $25.
