Answer:
f(2) = 9
Step-by-step explanation:
It's give in the question,
Two different functions are,
f(x) = 4x + 1
g(x) = -2x
Then we have to find the output value of function 'f' for the input value x = 2.
By substituting the value of x in the function 'f',
f(2) = 4(2) + 1
= 9
f(2) = 9

I need just the answer, no step to step
just divide the price by the amount of oz. I don't have a calculator but that's what you do. Just round according to money.
Answer:
1) [tex]\huge\boxed{\sf 5.7}[/tex]
2) [tex]\huge\boxed{6.4}[/tex]
Step-by-step explanation:
74 oz = $ 4.24
74 oz = 4.25 * 100 cents
74 oz = 425 cents
Divide bot sides by 74
1 oz = 425 / 74 ¢ / oz
1 oz = 5.7 ¢ / oz
[tex]\rule[225]{225}{2}[/tex]
42 oz. = $2.69
42 oz = 2.69 * 100 cents
42 oz = 269 cents
1 oz = 269 / 42 cents
1 oz = 6.4 ¢ / oz
[tex]\rule[225]{225}{2}[/tex]

Step-by-step explanation:
This is finding exact values of sin theta/2 and tan theta/2. I’m really confused and now don’t have a clue on how to do this, please help
First,
tan(θ) = sin(θ) / cos(θ)
and given that 90° < θ < 180°, meaning θ lies in the second quadrant, we know that cos(θ) < 0. (We also then know the sign of sin(θ), but that won't be important.)
Dividing each part of the inequality by 2 tells us that 45° < θ/2 < 90°, so the half-angle falls in the first quadrant, which means both cos(θ/2) > 0 and sin(θ/2) > 0.
Now recall the half-angle identities,
cos²(θ/2) = (1 + cos(θ)) / 2
sin²(θ/2) = (1 - cos(θ)) / 2
and taking the positive square roots, we have
cos(θ/2) = √[(1 + cos(θ)) / 2]
sin(θ/2) = √[(1 - cos(θ)) / 2]
Then
tan(θ/2) = sin(θ/2) / cos(θ/2) = √[(1 - cos(θ)) / (1 + cos(θ))]
Notice how we don't need sin(θ) ?
Now, recall the Pythagorean identity:
cos²(θ) + sin²(θ) = 1
Dividing both sides by cos²(θ) gives
1 + tan²(θ) = 1/cos²(θ)
We know cos(θ) is negative, so solve for cos²(θ) and take the negative square root.
cos²(θ) = 1/(1 + tan²(θ))
cos(θ) = - 1/√[1 + tan²(θ)]
Plug in tan(θ) = - 12/5 and solve for cos(θ) :
cos(θ) = - 1/√[1 + (-12/5)²] = - 5/13
Finally, solve for sin(θ/2) and tan(θ/2) :
sin(θ/2) = √[(1 - (- 5/13)) / 2] = 3/√(13)
tan(θ/2) = √[(1 - (- 5/13)) / (1 + (- 5/13))] = 3/2

Classify ACD by its angle measures.
Answer:
Right triangle
Step-by-step explanation:
Angle ACD is a right angle. Thus, angle ACD = 90°.
Any triangle that has one of its angles measuring 90° is said to be a right triangle.
Thus, triangle ACD has one of its angles measuring 90°. Therefore, ∆ACD is a right triangle.

what is the inverse function of f(x) = 4x - 1
Answer:
[tex]f(x) = \frac{x + 1}{4}[/tex]
Step-by-step explanation:
To inverse the function switch the places of x and y like this:
x = 4y - 1
Now, solve for y:
[tex]x + 1 = 4y\\\frac{x + 1}{4} = y[/tex]
It's that easy!

Ford Motor Company decided against building a new plant in California because of the high cost of taxes. The state of California proposed an assessment rate of 52% of the estimated market value of the plant. The tax rate proposal was $233.00 per $1,000 of assessed value. What would Ford Motor pay in property taxes per year if it decided to build a $25 million plant?
Answer:
$5825000
Step-by-step explanation:
You just take 23.3% of the 25 million dollars silly.
Joe sells used cars. He recorded the age (in years) of each car on his lot along with the number of kilometers it
had been driven. After plotting his results, Joe noticed that the relationship between the two variables was fairly linear, so he used the data to calculate the following least squares regression equation for predicting distance
driven from the age of the car:
y = 11,000 + 18,000x
What is the residual of a car that is 2 years old and has been driven 50,000 km?
Answer:3000 km
Step-by-step explanation:
The car will be 2 years old if it has been driven 50000km
Regression equationsGive the equation for predicting the distance driven from the age of the car expressed as:
y = 11,000 + 18,000xwhere:
x is the age (in years) of each cary is the number of kilometers it had been drivenIf the car is 2 years old, the residual of the car is given as:
y = 11,000 + 18,000x
y=11000 + 18000(2)
y = 11000 + 36000
y= 47000km
If the car has driven 57,000km, the age of the car will be expressed as:
50000 = 11000 + 18000x
50000 - 11000 = 18000x
39000 = 18000x
x = 39/18
y = 2 years
Hence the car will be 2 years old if it has been driven 50000km
