<h3>Solution:-</h3>

To convert temperature readings from celsius scale, formula used is -

$\green{ \underline { \boxed{ \sf{F = \frac{9}{5}C +32 }}}}$

where

F = temperature in Fahrenheit
C = temperature in Celsius

Putting Values -

$\begin{gathered}\\\implies\quad \sf F = \frac{9}{5}\times(-3) + 32 \\\end{gathered}$

$\begin{gathered}\\\implies\quad \sf -\frac{27}{5} + 32 \\\end{gathered}$

$\begin{gathered}\\\implies\quad \sf -5.4 + 32 \\\end{gathered}$

$\begin{gathered}\\\implies\quad \sf 26.6\degree F \\\end{gathered}$

Therefore, 26.6⁰ Fahrenheit is equivalent to -3⁰C.

Answer:

26.6 degrees

Step-by-step explanation:

Formula

(°C × 1.8) + 32 = °F

(-3°C × 9/5) + 32 = 26.6°F

26.6

Substitute $u=x^2+4$ and $du=2x\,dx$ . Then the integral transforms to

$\displaystyle \int \frac{x\,dx}{(x^2+4)^3} = \frac12 \int \frac{du}{u^3}$

Apply the power rule.

$\displaystyle \int \frac{du}{u^3} = -\dfrac1{2u^2} + C$

Now put the result back in terms of $x$ .

$\displaystyle \int \frac{x\,dx}{(x^2+4)^3} = \frac12 \left(-\dfrac1{2u^2} + C\right) = -\dfrac1{4u^2} + C = \boxed{-\dfrac1{4(x^2+4)^2} + C}$

!!Please Help!! Find the value of z to the nearest tenth.

serg [7]

Answer:

x = 14 $\sqrt{2}$

y = 14

z= 14 $\sqrt{3}$

Step-by-step explanation:

Notice that the top triangle is a 45-45-90 triangle and the triangle below is a 30-60-90 triangle.

Using the fact that the top triangle is a 45-45-90 triangle and also an isosceles triangle, we can see that x will be the same as its respective leg, 14 $\sqrt{2}$

Now, we must find a side length of the bottom triangle. We can use the Pythagorean Theorem to find the third side of the top triangle, which is also a side of the bottom triangle. We can find that the third side must be 28. We can now use this to find the other sides of the bottom triangle.

Since y is opposite to the 30 degree angle, it is half of the hypotenuse. The hypotenuse which we found earlier is 28, therefore, y is 14. z is then 14 $\sqrt{3}$ using either Pythagorean Theorem or special right triangle properties for 30-60-90.

Find the following percents. Round to the nearest thousandth when necessary. 6% of 300.

finlep [7]

300/x=100/6

(300/x)*x=(100/6)*x

300=16.6666666667*x

300/16.6666666667=x

x=18

Therefore the answer is "18."

Hope this helps!
