If the area of a rhombus is 120, and d1 is 4 cm more than twice the length of the shorter one, d2. What are the lengths of the d

melomori [17]

The formula for the diagonal of a rhombus is derived using the area of the rhombus. In other words, if the area and one of the diagonals is given, then the other diagonal can be calculated using the formula, p = (2 × Area)/q, where 'p' and 'q' are the two diagonals of the rhombus.

Celia thinks that because the drop between the first two points is so large, the best model might actually have a y- intercept a

victus00 [196]

The equation of Celia's exponential model is $y = 9.4 * 0.75^x$

<h3>How to estimate the model?</h3>

The table that completes the question is added as an attachment

The y-intercept is given as:

(0,9.4)

The ratios of successive data values are calculated as:

$r_1 = \frac{6.0}{10}= 0.6$

$r_2 = \frac{5.4}{6.0}= 0.9$

$r_3 = \frac{3.9}{5.4}= 0.72$

$r_4 = \frac{3.7}{3.9}= 0.95$

$r_5 = \frac{2.3}{3.7}= 0.62$

$r_6 = \frac{1.4}{2.3}= 0.61$

$r_7 = \frac{1.0}{1.4}= 0.71$

$r_8 = \frac{0.9}{1.0}= 0.9$

$r_9 = \frac{0.8}{0.9}= 0.89$

$r_{10} = \frac{0.5}{0.8}= 0.63$

The average of the above values is

$b = \frac{0.6 + 0.9 + 0.72 + 0.95 + 0.62 + 0.61 + 0.71 + 0.9 + 0.89 + 0.63}{10}$

Evaluate

b = 0.75

An exponential function is represented as:

$y = ab^x$

Where

a = 9.4 as in the y-intercept (0,9.4)

b = 0.75

Substitute these values in $y = ab^x$

$y = 9.4 * 0.75^x$

Hence, the Celia's exponential model is $y = 9.4 * 0.75^x$
