Given,
The total distance travelled is 476 miles.
The time taken by the boat for upstream is 14 hours.
The time taken by the boat for downstream is 34 hours.
Consider, The speed of the boat is B miles/hour.
The speed of the current is C miles/hour.
The speed at downstream is B+C miles/hour.
The speed at upstream is B-C miles/hour.
The formula of speed is,
For downstream,
For upstream,
Adding equation (1) and equation (2) then,
Substituting the value of B in equation (2),
Hence, the speed of current is 10 miles/hour and speed of boat is 24 miles/hour.
The given function is:
The statement A is true. Substituting x = 1 in given expression we get 0. So, (1,0) is the x-intercept of the function.
The statement B is false. There is no y-intercept of the function.
The statement C is false. The base of log is less than 1, so it will be a decreasing function.
The statement D is true.
The statement E if true. Range of the log function is set of all Real numbers.
The statement F is true. The given log function is defined for values of x greater than 0.
So the correct options are A, D, E and F

Answer:
HI = 8
TU = 45
Step-by-step explanation:
→ Find the scale factor enlargement
45 ÷ 10 = 4.5
→ Multiply JI by the scale factor to find it
10 × 4.5 = 45
→ Divide UV by the scale factor to find it
36 ÷ 4.5 = 8
Slope is -1/2 hope so that it's corrected
