Answer:

199.8 km to the 1 decimal point

Step-by-step explanation:

8:36 to 9:00 is 24 min

9:00 to 10:00 is 60 min

10:00 to 10:57 is 57 min

That's a total of 24 + 60 + 57 = 141 min = 141/60 hr.

d = rt = 141/60(85) = 199.8 km to the 1 decimal point

Danielle bought a house for $215,000. She financed $189,375 of the purchase price with a 15-year-fixed-rate mortgage with a 6.1%

Brilliant_brown [7]

Total cost of the house = $215,000
Amount financed through mortgage = $189,375
Amount paid through other means (such as cash) = 215,000-189,375 = $25,625
Rate = 6.1% = 0.061
Number of years = 15 years

Monthly payment, M = P[i(1+i/12)^12*15]/[(1+i/12)^12*15 -1] = 189,375[0.061/12(1+0.061/12)^12*15]/[(1+0.061/12)^12*15 - 1] = $1,608.30
Total amount paid = $25,625 + (M*12*15) = $25,625 + $289,494.56 = $315,119.56

Which of these functions has a domain of all real numbers except x=4.1?

nika2105 [10]

Answer:

$(A)y=\frac{2.5}{x-4.1} + 2.8$

Step-by-step explanation:

In the expressions, the value at which the domain of the function will be the set of all real numbers except x=4.1 is the value at which 4.1 makes the denominator equal to zero, i.e makes the fraction undefined.

Given the options

$(A)y=\frac{2.5}{x-4.1} + 2.8$

Setting the denominator to zero, x-4.1=0, x=4.1. The fraction is undefined at x=4.1

$(B)y=\frac{2.8}{x+4.1} -2.5$
