Answer:
125 - n
Step-by-step explanation:
n is unknown.
Answer:
1). 
= (200 - 
)
2). Inverse function represents the age of the client and 'x' represents the maximum heart rate of the client.
Step-by-step explanation:
Function representing the maximum heart rate is,
f(x) = 0.85(220 - x)
Here x = age of the client
Equation form of the function will be,
y = 0.85(220 - x)
To get the inverse of the given function, replace 'x' by 'y' and 'y' by 'x' and solve for y.
x = 0.85(220 - y)
220 - y =
y = 220 -
Now convert this equation into a function.
= (200 - )
Here inverse function represents the age of the client and 'x' represents the maximum heart rate of the client.
They gave you a set of numbers that you replace the variable x in the equation to see if it gives a correct answer so just do exactly that.
6 + 2x = 24
6 + 2(6) = 24
6 + 12 = 24
18 = 24 so incorrect. both sides are not equal to each other.
6 + 2x = 24
6 + 2(9) = 24
6 + 18 = 24
24 = 24 so correct. both sides are equal to each other.
6 + 2x = 24
6 + 2(15) = 24
6 + 30 = 24
36 = 24 so incorrect. both sides are not equal to each other.
6 + 2x = 24
6 + 2(16) = 24
6 + 32 = 24
38 = 24 so incorrect. both sides are not equal to each other.
so your answer is b) 9
hope this helps, God bless!
Answer: you would expect 6 to qualify for bonus round
Step-by-step explanation: because the 7 out of 14 qualified for the bonus round wich is 1/2 so 1/2 of 12 would be 6
Answer :
<u>A the triangle is not a right </u><u>triangle</u>
<u>D </u><u>costheta</u><u> </u><u><0</u>
The law of cosines says:
a²=b²+c²−2bccos(θ)
Rewriting:
2bccos(θ)=b²+c²−a²<0
So cos(θ)<0cos(θ)<0 since 2bc>02bc>0. Since 0<θ<π0<θ<π in any triangle,
π/2<θ<π
So:
1. θ is not an acute angle.
2 The triangle is not a right triangle. In a right triangle, one of the angles is 90 degrees and the other two are then less than 90 degrees. This triangle has an angle greater than 90 degrees.
3. cos(θ)<0 is true.
4. cos(θ)>0 is false -3 says cos(θ) is negative; a number can't be both positive and negative.
