Explain why x=4 is not in the domain of the function f(x)=√x-5 ?

lianna [129]

Since we are dealing with a radical then x - 5 ≥ 0, for real values

x = 4 is less than 5 , hence is not in the domain

A rectangular soccer field is 120 ft long by 64 ft wide. What dimensions would a scale drawing of the soccer field be if the fie

timofeeve [1]

Answer:

Hence dimension on drawing= 12 in by 6.4 in

Step-by-step explanation:

Actual dimension of the soccer field is 120 ft by 64 ft

Scale during drawing = 1in to 10 ft

Hence dimension on drawing = 120/10 by 64/10 = 12 in by 6.4 in

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 $y = 9.4 * 0.75^x$

the cost of state college tuition is currently at $22,500 per year and is rising at a rate of 4% each year. What will the same c

kvv77 [185]

Answer:

27000

Step-by-step explanation:

22,500 x .04=900

So it rises $900 each year

900 x 5=4500

It will increase by $4500 in 5 years

Add 22500+4500=27000
