The answer is (C) 2x+1/ 2x+5.

This is just finding like terms.

Like terms are terms that are the same, like 2x and 3x for example, would be like terms. (This is not in the problem by the way.) Just divide the like terms, and that's your answer.

I tried to give a good explanation but I'm super tired. Just trying to help.

If a snowball melts so that its surface area decreases at a rate of 5 cm2/min, find the rate at which the diameter decreases whe

mixas84 [53]

Answer:

The diameter decreases at the rate of 0.0796 cm/min when the diameter is 10 cm.

Step-by-step explanation:

A snowball is spherical, so it's area is given by the following formula:

$A = 4\pi r^{2}$

The radius is half the diameter so:

$A = 4\pi (\frac{d}{2})^{2}$

$A = 4\pi \frac{d^{2}}{4}$

$A = \pi d^{2}$

If a snowball melts so that its surface area decreases at a rate of 5 cm2/min, find the rate at which the diameter decreases when the diameter is 10 cm.

We have to find $\frac{dd}{dt}$ when $\frac{dA}{dt} = -5, d = 10$

$A = \pi d^{2}$

Applying implicit differentiation:

We have to variables(A and d), so:

$\frac{dA}{dt} = 2\pi d \frac{dd}{dt}$

$-5 = 2\pi (10) \frac{dd}{dt}$

$\frac{dd}{dt} = -\frac{5}{20\pi}$

$\frac{dd}{dt} = -0.0796$

The diameter decreases at the rate of 0.0796 cm/min when the diameter is 10 cm.

if (2x minus 1) is exactly divisible by 6 X square + ax - 4 and b x square - 11x + 3, then the value of b square minus a square

alexdok [17]

Step-by-step explanation:

Given that:-

$(2x - 1)$

is exactly divisible by

$6 {x}^{2} + ax - 4$

and

$b {x}^{2} - 11x + 3$

We need to simply, place the value of x.

$2x - 1 = 0$

$2x = 1$

$x = \frac{1}{2}$

Now,

$6 {( \frac{1}{2} )}^{2} + \frac{a}{2} - 4 = 0$

$\frac{3 + a}{2} = 4$

$3 + a = 4 \times 2 = 8$

$a = 8 - 3$

$a = 5$

Now, to find b.

$b {( \frac{1}{2}) }^{2} - \frac{11}{2} + 3 = 0$

$\frac{b}{4} - \frac{11}{2} = - 3$

$\frac{b - 22}{4} = - 3$

$b - 22 = - 12$

$b = 10$

is the answer.

Now, we need

${b}^{2} - {a}^{2} + a - b$

$100 - 25 + 100 + 5$

$= 205 - 25$

$= 180$

is the answer.

Hope it helps :D
