Answer:
- plane: 850 mph
- jet stream: 150 mph
Step-by-step explanation:
The speed of the plane is the average of the two speeds. The speed of the jet stream is half their difference.
against: (5600 mi)/(8 h) = 700 mi/h
with: (4000 mi)/(4 h) = 1000 mi/h
Plane's speed = (700 + 1000)/2 mi/h = 850 mi/h
jetstream speed = (1000 -700)/2 mi/h = 150 mi/h
The rate of the jet in still air is 850 mi/h; the rate of the jetstream is 150 mi/h.
Answer:
The correct option is <u>(C) Exponential growth</u>.
Step-by-step explanation:
The simplest exponential function is: f(x) = , a>0, a≠1
If the x is positive then graph of exponential is increasing and if the x is negative then graph of exponential is decreasing.
In given function
x is positive so, it is graph of exponential growth.
Hence, the correct option is <u>(C) Exponential growth</u>.
Answer:
x = -24
Step-by-step explanation:
First, distribute 2 to all terms within the parenthesis:
2(x + 11) =
2 * x = 2x
2 * 11 = 22
2x + 22 = -26
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operations, and stands for:
Parenthesis
Exponents (& Roots)
Multiplications
Divisions
Additions
Subtractions
~
First, subtract 22 from both sides of the equation:
2x + 22 (-22) = -26 (-22)
2x = -26 - 22
2x = -48
Next, divide 2 from both sides of the equation:
(2x)/2 = (-48)/2
x = -48/2
x = -24
x = -24 is your answer.

The answer ur looking for is 1,448
Answer:
3x + 7 + 5
Step-by-step explanation:
I could be wrong... there are 3 x's so that would be 3x, and then the 7 and 5. sorry if i'm wrong
