You can choose between two telephone companies. Company A has a monthly charge of $10 plus 5¢ a minute for each minute of long d

Diano4ka-milaya [45]

Answer: Company A would be a better deal for number of minutes over 200

Step-by-step explanation:

Let x represent the number of minutes that you would use with either company A or company B.

Company A has a monthly charge of $10 plus 5¢ a minute for each minute of long distance calls. It means that the cost of x minutes of long distance call is

10 + 0.05x

Company B has a monthly charge of $8 plus 6¢ a minute for long distance calls. It means that the cost of x minutes of long distance call is 10 + 0.05x

8 + 0.06x

For Company A to be a better deal, it means that

10 + 0.05x < 8 + 0.06x

10 - 8 < 0.06x - 0.05x

2 < 0.01x

0.01x > 2

x > 2/0.01

x > 200

R is the first quadrant region enclosed by the x-axis and the curve y = 2x + b, and the line x = b, where b > 0. Find the val

Elis [28]

The area of $R$ is given by the integral

$\displaystyle\int_0^b(2x+b)\,\mathrm dx=288$

Integrating yields

$(x^2+bx)\bigg|_{x=0}^{x=b}=(b^2+b^2)-(0+0)=2b^2$

So you have

$2b^2=288\implies b^2=144\impiles b=12$

From least to greatest, what are the measures of the next two angles with positive measure that are coterminal with an angle mea

Gennadij [26K]

Answer: The measures of the next two angles with positive measure are,

610°, 970°

Step-by-step explanation:

Co-terminal Angles of an angle are those angles who share the same initial side and terminal sides to that angle.

They are found by adding or subtracting 360° to the angle,

That is, if Ф is an angle,

Then its co-terminal angles are Ф + 360°n

Where, n is an integer ( Positive or negative)

Here, Ф = 250°

For finding next two angles with positive measure,

n = 1 and n = 2

Hence, the measures of the next two angles with positive measure are,

(250° + 1 × 360°), (250° + 2× 360°)

610°, 970°
