Answer:
L = 14/
<u>OR</u> 9.899
Step-by-step explanation:
cos(angle) = adjacent/ hypotenuse
hypotenuse = length of ladder
adjacent = 7 feet
length of ladder = L
1/L = cos(45)/7
L = 7/cos(45)
<u><em>MAKE SURE CALCULATOR IS IN DEGREE MODE</em></u>
L = 7/(
/2)
L = 14/
Using calculator
Answer=57
Answer:
0.448 seconds
Step-by-step explanation:
d = -16t² -4t + 412
find t when d = 407
substituting d = 407 into the equation:
407 = -16t² -4t + 412 (subtract 407 from both sides)
-16t² -4t + 412 - 407 = 0
-16t² -4t + 5 = 0 (multiply both sides by -1)
16t² + 4t - 5 = 0
solving using your method of choice (i.e completing the square or using the quadratic equation), you will end up with
t = (-1/8) (1 + √21)= -0.70 seconds (not possible because time cannot be negative)
or
t = (-1/8) (1 -√21) = 0.448 seconds (answer)

Answer:
lg22/lg6
Step-by-step explanation:
6^u = 22
lg(6^u) = lg22
ulg6 = lg22
u = lg22/lg6
