Which of the following shapes have an area of 48 square feet? Select all that apply.
yKpoI14uk [10]
I think 2,3,4 or B,C,D would be correct.

The area of a triangle is (b•h)/2
And the area of a rectangle and parallelogram would just be b•h

1) 8(6) = 48/2 =24

2) 9(10 2/3) = 96/2 =48

3) 19.2(2.5) = 48

4) 16(3) = 48

Hope this is right and hope it helps. Have a good day

The IQR is 42.5

Step-by-step explanation:

Interquartile range is the difference of third and first quartile.

First of all we have to find the median for that purpose the data has to be arranged in ascending order. The data is already in ascending order.

As the number of values are odd

n=21

The median will be: (\frac{n+1}{2}) th\ term

Putting n=21

(\frac{21+1}{2})th\ term\\=(\frac{22}{2})th\ term\\= 11th\ term

The 11th term is 133

So median = 133

Now the data is divided into two halves

One is: 98, 100, 101, 102, 108, 109, 111,118, 129, 132

2nd is: 135, 135, 145, 146, 146, 156, 170 176, 180, 180

Q1 will be the median of first half and Q3 will be the median of 2nd half.

As now the halves contain even number of values, the medians will be the average of middle two values

<u>For First Half:</u>

98, 100, 101, 102, <u>108, 109</u>, 111,118, 129, 132

Q_1 = \frac{108+109}{2}\\Q_1 = \frac{217}{2}\\Q_1 = 108.5

<u>For Second Half:</u>

135, 135, 145, 146, 146, 156, 170 176, 180, 180

Q_2 = \frac{146+156}{2}\\Q_2 = \frac{302}{2}\\Q_2 = 151

Now

<u>Interquartile Range:</u>

IQR = Q_3-Q_1\\= 151-108.5\\=42.5

Hence,

The IQR is 42.5

Condensing Logarithmic Expressions In Exercise, use the properties of logarithms to rewrite the expression as the logarithm of a
yKpoI14uk [10]

Answer:

4ln [\frac{x^2 (x^3-1)}{x-5}]

Step-by-step explanation:

For this case we have the following expression:

4[ln(x^3-1) +2ln(x) -ln(x-5)]

For this case we can apply the following property:

a log_c (b) = log_c (b^a)

And we can rewrite the following expression like this:

2 ln(x) = ln(x^2)

And we can rewrite like this our expression:

4[ln(x^3-1) +ln(x^2) -ln(x-5)]

Now we can use the following property:

log_c (a) +log_c (b) = log_c (ab)

And we got this:

4[ln(x^3-1)(x^2) -ln(x-5)]

And now we can apply the following property:

log_c (a) -log_c (b) = log_c (\frac{a}{b})

And we got this:

4ln [\frac{x^2 (x^3-1)}{x-5}]

And that would be our final answer on this case.
