The left side of a solid block is held at a constant temperature of 200°C. The temperature profile within the block is given by

T=200−5x−x2 where x is the distance from the left side of the block in centimeters and T is the temperature in degrees Celsius of the block at location x. At what value of x is T=50°C?

Answer:

with T = 50⁰C, we have:

50 = 200 - 5x - x²

<=> x² + 5x = 150

<=> x² + 5x - 150 = 0

=> x = 10

336 divided by 12 using partial quotients
tensa zangetsu [6.8K]

Answer:

The partial quotients are 20 and 8. The quotient is 28.

Step-by-step explanation:

The dividend is 336 and divisor is 12.

Find the easy factors of 12, which are less than 336.

12\times 10=120

12\times 20=240

12\times 30=360

Since 360>336, therefore 30 cannot be a partial quotient.

So, 20 is a partial quotient. Subtract 240 from 336. Apply this process till the dividend become 0.

The remaining dividend is

336-240=96

Find the easy factors of 12, which are less than 96.

12\times 8=96

The number 8 is a partial quotient.

96-96=0

Now the dividend is zero, so the partial quotients are 20 and 8. The quotient is the sum of partial quotients

20+8=28

The quotient is 28.

These proteins identify and lock on to an antigen (pathogen) and then tell other parts of the body to destroy the germ
tankabanditka [31]

Answer:

Answer is D.

Lymphocytes.

Explanation.

How Does the Immune System Work? When the body senses foreign substances (called antigens), the immune system works to recognize the antigens and get rid of them. B lymphocytes are triggered to make antibodies (also called immunoglobulins). These proteins lock onto specific antigens.

A cone has a radius of 4 units and a height of 6 units. Its volume is (A. 96 / B. 100.48 / C. 301.44 / D. 401.92) cubic units. I
Fed [463]

Answer:

<h2>A cone: B. V = 100.48 cubic units</h2><h2>A cylinder: C. V = 301.44 cubic units</h2>

Step-by-step explanation:

The formula of a volume of a cone:

V=\dfrac{1}{3}\pi r^2H

<em>r</em> - radius

<em>H</em> - height

We have <em>r = 4 u</em> and <em>H = 6 u</em>. Substitute:

V=\dfrac{1}{3}\pi(4^2)(6)=\dfrac{1}{3}\pi(16)(6)=\dfrac{1}{3}\pi(96)=32\pi\ u^3

\pi\approx3.14\to V\approx(32)(3.14)=100.48\ u^3

If the cylinder has the same radius and height as a cone, then the volume of the cylinder is three times larger than the volume of the cone.

Therefore, the volume of acylinder:

V\approx3(100.48)=301.44\ u^3

Why?

The formula of a volume of a cone:

V_{cone}=\dfrac{1}{3}\pi r^2H

The formula of a volume of a cylinder:

V_{cylinder}=\pi r^2H

Therefore

V_{cone}=\dfrac{1}{3}V_{cylinder}\to V_{cylinder}=3V_{cone}

If the radius and height are the same.
