Which equation represents an exponential function that passes through the point (2 80)f(x) 4(x)5 f(x) 5(x)4 f(x) 4(5)x f(x) 5(4)x?
To find the exponential function that passes through the point (2, 80), we can test the given options. The equation ( f(x) = 4(5)^x ) fits, as substituting ( x = 2 ) gives ( f(2) = 4(5^2) = 4 \times 25 = 100 ), which does not match. The option ( f(x) = 5(4)^x ) results in ( f(2) = 5(4^2) = 5 \times 16 = 80 ), which is correct. Therefore, the equation is ( f(x) = 5(4)^x ).
If father is three times as old as son 5 years ago he was 4 times age of his son what is son age?
Let F = father's age Let S = son's age F = 3S F - 5 = 4(S-5) F - 5 = 4S -20 F = 4S - 15 F = 3S 3S = 4S-15 S = 15, age of son
How do you play viva la vida on trumpet?
C# 5 times, then D# 5 times, then G# 4 times, and then, depending on which part of the song, it's F on the D string 5 times or F on the C string 5 times. Happy Viva la Viding!! ;-)
If f(x) 2x - 5 then f(4) is .?
To find ( f(4) ) for the function ( f(x) = 2x - 5 ), substitute ( x ) with 4. This gives you ( f(4) = 2(4) - 5 = 8 - 5 = 3 ). Therefore, ( f(4) ) is 3.
Four fifths of the sum of 4 and f?
4/5 (4 + f) = 4(4+f)/5
What does 5 f of f mean?
5 times the function of f
One fourth of f is added to 5?
5 +1/4 f = 5 + f/4
What is the formula of degrees C to degrees F?
If you take the degrees Celsius times 9/5 and add 32 degrees, you will get the degrees Fahrenheit. °C x 9/5 + 32 = °F
What is -100 degrees c converted to Fahrenheit?
C divided by 5 times 9 the add 32.-100 divided by 5 then times 9 then add 32=-148Memorize you benchmarksC F-40= -400 = 32100= 21237= 98.6
What is f in 7 times 5 times f equals 7070?
f = 202 because 7*5*202 = 7070
Fathers age is 4 times that of his son 5 years back it was 7 times His age now is?
It's not solvable: Proof that it's not solvable: 2 simultaneous equations - let F =father and S=son F = 4S (father is 4 times son's age) and F-5=7S (father minus 5 years equals 7 times son's age). Combining both gives 4S=7S+5 which is 3S=-5. Clearly you cannot have a negative age, which makes the question nonsensical.
What is f0 equals 3x-4 over 5?
f(x) = (3x - 4)/5 f(0) = [3(0) - 4]/5 = -4/5
