Answer: 1.875 as a decimal, and 1 7/8 as a mixed number
Step-by-step explanation:
First find Y
using the Pythagorean theorem
y = sqrt (3^2 -1^2)
y = sqrt(8)
y = 2sqrt(2)
now you can use Y to find Z
Z= sqrt( y^2 + 8^2)
z = 6sqrt(2)
the answer is D
A function cannot have the same value of x associated with different values of y.
Think about the straight line test!
The answer is a.
The model says a=.25t+29
a) since 1995 is 25 years after 1970 we have
a=.25*25+29=6.25+29=35.25 yrs old
b) since 2015 is 45 yrs since 1960 we have
a=.25*45+29=11.25+29=40.25, or 40.3 rounded to the nearest tenth
