Answer:
The inverse of f is [tex]f^{-1}[/tex] = (x -2)/4
Step-by-step explanation:
To find the inverse of f(x) = 4x + 2 , interchange the variables and solve for y.
Rewrite f(x) = 4x + 2 as x = 4y + 2 then solve for y
x -2 = 4y
(x - 2)/4 = y

1. The Sky Tower in Auckland, New Zealand is the tallest man-made structure in the southern
hemisphere at a height of 328 meters. One of the popular tourist attractions in Auckland is
to jump off the top of the tower or to walk around the outside observation deck. On vacation, Sydney was walking around the outside of the Sky Tower and threw an apple with an initial velocity of 40 mph or 17.882 meters per second.
Part A: How many seconds will it take the apple to hit the ground (ignoring air resistance)? Round your answer to the nearest tenth of a second.

Assume that adults have iq scores that are normally distributed with a mean of u = 105 and a standard deviation =20 find the probability that a randomly selected adult has an iq less than 129
Answer:
P(X<129) ≈ 0.8849
Step-by-step explanation:
I've attached a graph of the normal distribution to help you visualize the problem. To calculate this on a TI-84, we can use the normalcdf function to find the area between the end of the left-tail of the normal distribution to x=129, hence, we are finding P(X<129). We can write this as normalcdf(-1e99,129,105,20) ≈ 0.8849, therefore, the probability that a randomly selected adult has an IQ less than 129 is about 0.8849 or about 88.49% likely to occur.
Help me please. It’s for my geometry class and I don’t understand it.
Answer:
the answer is 29 degrees
Step-by-step explanation:
180 is the total of all the angles added together so if you subtract the 122 from 180 and divide by 2 you can get 29 for both and if you add it all together you should get 180 :)
Answer:
29
Step-by-step explanation:
pretty ez, so like a triangle got 180 degress total. what u gota do my man, is substract 122 from it. And u get 58 and they both are equal so u divide by 2 and u get 29.

Find the Greatest Common Factor of 20, 30 and 55
Answer:
5
is the answer dont over think it and try plz bc its very easy
The Greatest Common Factor of 20, 30, and 55 will be 5.
What is the number?A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.
It is given that, the numbers 20, 30, and 55.
The biggest divide between the two numbers is the greatest common factor. List each number's prime factors before calculating its greatest common factor.
20=5×2×2
30=5×2×3
55=5×11
One 2 and one 3 are the same for 20, 30, and 55. We multiply them to obtain the GCF, so the GCF of 20, 30, and 55 is 5.
Since we frequently work with fractions and they are prevalent in daily life, the greatest common factors (GCF) are very helpful. A fraction or ratio can be successfully simplified by determining the GCF of the denominator and numerator.
Thus, the Greatest Common Factor of 20, 30, and 55 will be 5.

Which equation represents a constant of proportionality of 25? *
12 points
F. x + 25 = y
G. 25x = y
H. x − 25 = y
J. 5x = y
Answer:
G
Step-by-step explanation:
An equation of proportionality has the form
y = kx ← k is the constant of proportionality
y = 25x ← has this form with k = 25
y = 5x ← has this form with k = 5
The required equation is y = 25x with k = 25 → G

Geometry N.6 properties of parallelograms
Answer:
72
Step-by-step explanation:
If you take s + 19 = 8s - 100 , you will get 17, so s = 17. Plus 17 into 4s + 4 and you will get 72. DC = BE, so BE = 72.

Pls say if it’s no solution/infinite/many solutions
Answer:
No solution
Step-by-step explanation:
Answer:
No Solution
Step-by-step explanation:
to solve for 'x' distribute the 2 on the left side and the 5 on the right side:
17 + 16x - 10 = 10 + 25x - 9x
combine 'like terms':
7 + 16x = 10 + 16x
There is no value for 'x' that would ever make the two sides equal ∴
No Solution
