Answer:

d = |- 5- 9|

Step-by-step explanation:

Given

Initial = 9^\circ F

Final = -5^\circ F

Required

Determine the difference

Represent this with d.

d is calculated using

d = |Final - Initial|

The equation becomes

d = |- 5- 9|

If a=mg-kv2/m,find,correct to the nearest whole number the value of v when a=2.8,m=12,g=9.8 and k=8/3
RUDIKE [14]

Answer:

The value of v is ± 22.729.

Step-by-step explanation:

Let be a=m\cdot g -\frac{k\cdot v^{2}}{m}, the variable v is now cleared:

\frac{k\cdot v^{2}}{m}=m\cdot g -a

k\cdot v^{2} = m^{2}\cdot g- m\cdot a

v^{2} = \frac{m^{2}\cdot g - m\cdot a}{k}

v =\pm \sqrt{\frac{m^{2}\cdot g-m\cdot a}{k} }

If a = 2.8, m=12, g = 9.8 and k = \frac{8}{3}, the value of v is:

v=\pm \sqrt{\frac{(12)^{2}\cdot (9.8)-(12)\cdot (2.8)}{\frac{8}{3} } }

v \approx \pm 22.729

The value of v is ± 22.729.

Multiply and Simplify<br> (x-5)(x^3 - 6x - 4)
Whitepunk [10]

Answer:

x4−5x3−6x2+26x+20

Step-by-step explanation:

(x−5)(x3−6x−4)

=(x+−5)(x3+−6x+−4)

=(x)(x3)+(x)(−6x)+(x)(−4)+(−5)(x3)+(−5)(−6x)+(−5)(−4)

=x4−6x2−4x−5x3+30x+20

=x4−5x3−6x2+26x+20

Write the quadratic equation that has roots -1-rt2/3 and -1+rt2/3 if its coefficient with x^2 is equal to 1
weeeeeb [17]

The equation of the quadratic function is f(x) = x²+ 2/3x - 1/9

<h3>How to determine the quadratic equation?</h3>

From the question, the given parameters are:

Roots = (-1 - √2)/3 and (-1 + √2)/3

The quadratic equation is then calculated as

f(x) = The products of (x - roots)

Substitute the known values in the above equation

So, we have the following equation

f(x) = (x - \frac{-1-\sqrt{2}}{3})(x - \frac{-1+\sqrt{2}}{3})

This gives

f(x) = (x + \frac{1+\sqrt{2}}{3})(x + \frac{1-\sqrt{2}}{3})

Evaluate the products

f(x) = (x^2 + \frac{1+\sqrt{2}}{3}x + \frac{1-\sqrt{2}}{3}x + (\frac{1-\sqrt{2}}{3})(\frac{1+\sqrt{2}}{3})

Evaluate the like terms

f(x) = x^2 + \frac{2}{3}x - \frac{1}{9}

So, we have

f(x) = x²+ 2/3x - 1/9
