Answer:

x = 2

Step-by-step explanation:

Step 1 is to Distribute which is basically to multiply:

-20x + 10 = -6 -12x

Next collect like terms

So add 20x to both sides: 10 = -6 + 8x

Next add 6 to both sides: 16 = 8x

Finally divide both sides by 8 to get the value of x:

x = 2

STEP ONE MULTIPLY: -20x+10=-6-12x
STEP TWO BRING TO OTHER SIDE: -8x+10=-6
STEP THREE CONTINUE WITH OTHER SIDE: -8x=-16
STEP FOUR DIVIDE:
x=2

A block of wood has a mass of 120g and a volume of 200cm3. What is the density of the wood?

ozzi

Density=mass/volume
given mass=120g and volume=200cm3
density= $\frac{120g}{200cm^3}=\frac{3}{5} \space\ \frac{g}{cm^3}$ or abot 0.6

the density is $0.6 \space\ \frac{g}{cm^3}$

1. Let a and b be coefficients such that

$\dfrac1{x(2x+3)} = \dfrac ax + \dfrac b{2x+3}$

Combining the fractions on the right gives

$\dfrac1{x(2x+3)} = \dfrac{a(2x+3) + bx}{x(2x+3)}$

$\implies 1 = (2a+b)x + 3a$

$\implies \begin{cases}3a=1 \\ 2a+b=0\end{cases} \implies a=\dfrac13, b = -\dfrac23$

so that

$\dfrac1{x(2x+3)} = \boxed{\dfrac13 \left(\dfrac1x - \dfrac2{2x+3}\right)}$

2. a. The given ODE is separable as

$x(2x+3) \dfrac{dy}dx} = y \implies \dfrac{dy}y = \dfrac{dx}{x(2x+3)}$

Using the result of part (1), integrating both sides gives

$\ln|y| = \dfrac13 \left(\ln|x| - \ln|2x+3|\right) + C$

Given that y = 1 when x = 1, we find

$\ln|1| = \dfrac13 \left(\ln|1| - \ln|5|\right) + C \implies C = \dfrac13\ln(5)$

so the particular solution to the ODE is

$\ln|y| = \dfrac13 \left(\ln|x| - \ln|2x+3|\right) + \dfrac13\ln(5)$

We can solve this explicitly for y :

$\ln|y| = \dfrac13 \left(\ln|x| - \ln|2x+3| + \ln(5)\right)$

$\ln|y| = \dfrac13 \ln\left|\dfrac{5x}{2x+3}\right|$

$\ln|y| = \ln\left|\sqrt[3]{\dfrac{5x}{2x+3}}\right|$

$\boxed{y = \sqrt[3]{\dfrac{5x}{2x+3}}}$

2. b. When x = 9, we get

$y = \sqrt[3]{\dfrac{45}{21}} = \sqrt[3]{\dfrac{15}7} \approx \boxed{1.29}$

Do the results support or contradict the common belief that the mean body temperature is 98.6degreesF? A. The results contradic

nata0808 [166]

Answer:

A. The results contradict the belief that the mean body temperature is 98.6 °F because both the mean and the median are less than 98.6 °F.

Step-by-step explanation:

Assume the temperature data were those in the table below.

You would have calculated that

Mean = 97.9 °F

Median = 97.9 °F

These observations contradict the belief that the mean body temperature is 98.6 °F.

A 2017 study found the mean oral temperature of more than 35 000 British patients was 97.9 °F.
