Answer:

see beleow

Step-by-step explanation:

Let's solve your equation step-by-step.

5.1+2.3x=23.5

Step 1: Simplify both sides of the equation.

2.3x+5.1=23.5

Step 2: Subtract 5.1 from both sides.

2.3x+5.1−5.1=23.5−5.1

2.3x=18.4

Step 3: Divide both sides by 2.3.

2.3x

2.3

=

18.4

2.3

\textit{using the disc method}
\\\\
V=\int\limits_{0}^{6}\pi \left[ sin\left( \frac{\pi x}{6} \right) \right]^2\cdot dx\implies \pi\int\limits_{0}^{6} \left[ sin\left( \frac{\pi x}{6} \right) \right]^2\cdot dx

\bf \textit{now, let us check the double angle identities}

cos(2\theta)=
\begin{cases}
cos^2(\theta)-sin^2(\theta)\\
\boxed{1-2sin^2(\theta)}\\
2cos^2(\theta)-1
\end{cases}
\\\\\\
thus\implies cos(2\theta)=1-2sin^2(\theta)\implies 2sin^2(\theta)=1-cos(2\theta)
\\\\\\
sin^2(\theta)=\cfrac{1-cos(2\theta)}{2}\qquad thus\\\\
-----------------------------

\bf \pi\int\limits_{0}^{6} \left[ sin\left( \frac{\pi x}{6} \right) \right]^2\cdot dx\implies 
\pi\int\limits_{0}^{6} \cfrac{1-cos\left(2\cdot  \frac{\pi x}{6} \right)}{2}\cdot dx
\\\\\\
\pi\int\limits_{0}^{6}\cfrac{1}{2}dx-\pi \cdot \cfrac{1}{2}\pi\int\limits_{0}^{6}cos\left(\frac{\pi x}{3} \right)dx
\\\\\\
\left[\cfrac{\pi x}{2}-\cfrac{\pi }{2}\cdot \cfrac{sin\left(\frac{\pi x}{3} \right)}{\frac{\pi x}{3} }  \right]\implies \left[ \cfrac{\pi }{2}x-\cfrac{3sin\left(\frac{\pi x}{3} \right)}{2x} \right]_0^6

and surely, you'd know how to get the values for the bounds there

The number of measles cases increased 13.6 % to 57 cases this year, what was the number of cases prior to the increase? (Express
ELEN [110]

Answer:

The number of cases prior to the increase is 50.

Step-by-step explanation:

It is given that the number of measles cases increased by 13.6% and the number of cases after increase is 57.

We need to find the number of cases prior to the increase.

Let x be the number of cases prior to the increase.

x + 13.6% of x = 57

x+x\times \frac{13.6}{100}=57

x+0.136x=57

1.136x=57

Divide both the sides by 1.136.

\frac{1.136x}{1.136}=\frac{57}{1.136}

x=50.176

x\approx 50

Therefore the number of cases prior to the increase is 50.
