Answer:
Let the current speed be "c";
Then the boat speed in still wate is "5c":
-----------------------
Upstream speed:
distance = 12 miles ; rate = 5c-c = 4c mph ; time = 12/4c = 3/c hrs
---------------------------
Downstream speed:
distance = 12 miles ; rate = 5c+c = 6c mph ; time = 12/6c = 2/c hrs
Step-by-step explanation:
Equation:
time + time = 2 1/2 hrs
3/c + 2/c = 5/2
Multiply thru by 2c to get:
6 + 4 = 5c
c = 2 mph (speed of the current)
5c = 10 mph (speed of the boat in still water)
ANSWER
Phase shift: 2 units right.
EXPLANATION
The given sine function is
In mathematics, a horizontal shift may also be referred to as the phase shift.
This function is shifted to the right 2 units.
Answer:
It would be constant.
Step-by-step explanation:
Since there is no x value, the line will have no slope and just be horizontal about y= -2.
<span>The y-intercept of a function is given by the initial value of a function. It is the value of the function when x = 0.
Given the functions
A. Blake is tracking his savings account with an interest rate of 5% and a original deposit of $6.
The y-intercept for this function is the initial deposit which is $6.
B.
x g(x)
0 6
1 2
2 10
The y-intersept for this function is 6 which isthe value of the function g(x) when x = 0.
C. The function h of x equals 4 to the x power, plus 3
When x = 0,
Thus the y-intecept is 4.
D. j(x) = 10(2)^x
when x = 0,
Thus, the y-intercept is 10.
Thereforen the function with the highest y-intercept is
which has a y-intercept of 10.

10 people who build at the same rate can frame a house in 6 days. That means it will take one person days to finish the house.
Which means that it will take 4 people days to finish the house.
So, the fractional part of the house 4 people can frame in 3 days will be
Thus, Option D is the correct answer.
