For
ax^2+bx+c=0
discriminatn is b^2-4ac

a=4
b=12
c=9
discriinat is
12^2-4(4)(9)=
144-144
0

the discrminat is 0

Pete sold 150 shares of stock a at $10.98 per share through his broker. His broker charges $28 per trade. How much money did Pet

Andrews [41]

Answer:

$1619

Step-by-step explanation:

From the first statement, he sold 150 shares at $10.98 per trade, this means the total amount in which the sale cost is 10.98 × 150 =

$1647

Now we are told that the broker charged an amount of $28 per trade. Hence , the amount left after the broker had removed his charges is the total amount minus the broker fee.

That equals, 1647 - 28 which is $1619

A rather flimsy spherical balloon is designed to pop at the instant its radius has reached 3 centimeters. Assuming the balloon i

Anni [7]

Answer:

The radius is growing at the rate of 0.09 centimeter per second at the instant it pops.

Step-by-step explanation:

We are given the following information in the question:

A spherical balloon is designed to pop at the instant its radius has reached 3 centimeters.

The balloon is filled with helium at a rate of 10 cubic centimeters per second .

$\displaystyle\frac{dV}{dt} = 10~cm^3/sec.$

We have to find fast the radius is growing at the instant it pops.

Volume of spherical balloons =

$\displaystyle\frac{4}{3}\pi r^3$

Differentiating, we get,

$\displaystyle\frac{dV}{dt} = \frac{4}{3}\pi 3r^2 \displaystyle\frac{dr}{dt} = 4\pi r^2 \displaystyle\frac{dr}{dt}$

Putting the values, we get,

$10 = 4\times 3.14\times (3)^2\times \displaystyle\frac{dr}{dt}\\\\\frac{dr}{dt} = \frac{10}{4\times 3.14\times (3)^2} = 0.0884 \approx 0.09\\\\\frac{dr}{dt} = 0.09\text{ centimeter per second}$

The radius is growing at the rate of 0.09 centimeter per second at the instant it pops.
