Mathematics
1 answer:
Vitek1552 [10]2 years ago

Answer:

log9

Step-by-step explanation:

Using the rules of logarithms

logx + logy = log(xy)

logx - logy = log(\frac{x}{y})

logx^{n} ⇔ nlogx

Given

2(log18- log3) + \frac{1}{2}log\frac{1}{16}

= 2(log(\frac{18}{3} ) ) + log(\frac{1}{16}) ^{\frac{1}{2} }

= 2log6 + log\frac{1}{4}

= log6² + log\frac{1}{4}

= log36 + log\frac{1}{4}

= log( 36 × \frac{1}{4} )

= log9

A certain bridge arch is in the shape of half an ellipse 106 feet wide and 33.9 feet high. At what horizontal distance from the
nata0808 [166]

Answer:

The horizontal distance from the center is 49.3883 feet

Step-by-step explanation:

The equation of an ellipse is equal to:

\frac{x^2}{a^{2} } +\frac{y^2}{b^{2} } =1

Where a is the half of the wide, b is the high of the ellipse, x is the horizontal distance from the center and y is the height of the ellipse at that distance.

Then, replacing a by 106/2 and b by 33.9, we get:

\frac{x^2}{53^{2} } +\frac{y^2}{33.9^{2} } =1\\\frac{x^2}{2809} +\frac{y^2}{1149.21} =1

Therefore, the horizontal distances from the center of the arch where the height is equal to 12.3 feet is calculated replacing y by 12.3 and solving for x as:

\frac{x^2}{2809} +\frac{y^2}{1149.21} =1\\\frac{x^2}{2809} +\frac{12.3^2}{1149.21} =1\\\\\frac{x^2}{2809}=1-\frac{12.3^2}{1149.21}\\\\x^{2} =2809(0.8684)\\x=\sqrt{2809(0.8684)}\\x=49.3883

So, the horizontal distance from the center is 49.3883 feet

Identify which of these designs is most appropriate for the given​ experiment: completely randomized​ design, randomized block​
Ksju [112]

Answer:

Completely Randomized Design

Step-by-step explanation:

In a completely randomized design, the samples are randomly assigned to the treatment without creating any blocks or groups.

Like here, in the given scenario, we do not have to divide subjects in two groups as they are all same.

Whereas, in a randomized block design, the participants are divided into subgroups in a way, that the variability within the blocks is less than the variability between blocks.

After dividing, the participants within each block are randomly assigned to treatment conditions.

Hence, the completely randomized design is used here.
