A.) 7^4x = 10
log base 10 (7^4X) = log base 10 (10)
4x log base 10 (7) = 1
4x (0.8451) = 1
3.3804x = 1
x = 0.2958
b.) ln(2) + ln(4x-1) = 5
ln (2 * 4x-1) = 5
ln (8x-2) = 5
log base (3) (8x-2) = 5
e^5 = 8x-2
e^5+2 = 8x
x = 18.8016
Answer:
he first one and the third one
Step-by-step explanation:
X 25*24*23*22*21*20*19
which gives you
2,422,728,000
Tan θ = 7/8
θ = tan^-1 (7/8) = 41.2 degrees
cos θ = 0.7526
