MULTIPLE CHOICE QUESTION A car travels 120 miles in 2 hours. It goes an average of South East direction. What is its velocity? 60 mph south east 45 mph 45 mph south east 60 mph
Answer:
60 miles per hour southeast.
Step-by-step explanation:
We are told that the car is moving southeasternly, so that answers the question right off the bat. The car is moving 120 miles per 2 hours. We need to know how much it moves in one hour though, so we must divide hours and miles by 2. We ger 60 miles per hour.
Velocity will be 60 mph southeast.
What is the difference between velocity and speed?The distance that an item travels in a unit of time is referred to as its speed. It merely takes into account the size of the item and ignores its orientation. Speed is referred to as a scalar quantity in this way. When referring to velocity, however, it is said that velocity is the rate at which displacement changes. A vector quantity, that is.
Given distance traveled by car is 120 miles in 2 hours. Since speed is distance divided by time.
Speed = 60 mph
Also, there is a given direction which is southeast.
Therefore, the velocity of the car will be 60 mph southeast.

Functions:
In image 1: Evaluate the functions
In image 2: Given the functions, find their inverse, if possible and if not possible, redefine Domain or Range
Answer:
Image 11. x = 4
f(4) = (- 3*4 + 1) / 6 = -11/62. x = -2/3
f(-2/3) = -3*(-2/3) + 10 = 2 + 10 = 123. x = -5
f(-5) = [tex]\sqrt{-(-5)/20}[/tex] = [tex]\sqrt{5/20}[/tex] = [tex]\sqrt{1/4}[/tex] = 1/2Image 2To work out the inverse, substitute f(x) with x and x with y, then solve for y. The new function is the inverse of the given.1. f(x) = 5x + 3
x = 5y + 3 ⇒ 5y = x - 3 ⇒ y = (x - 3)/5f⁻¹(x) = (x - 3)/52. f(x) = 4/5x
x = 4/5y ⇒ y = 5/4xf⁻¹(x) = 5/4x3. f(x) = (2x + 7)/4
x = (2y + 7)/4 ⇒ 2y + 7 = 4x ⇒ 2y = 4x - 7 ⇒ y = 2x - 3.5f⁻¹(x) = 2x - 3.54. f(x) = (2x + 7) /(x + 3) = 2 + 1/(x + 3)
x = 2 + 1/(y + 3) ⇒ x - 2 = 1/(y + 3) ⇒ y + 3 = 1/(x - 2) ⇒ y = (1 - 3x + 6)/(x - 2) ⇒ y = (7 - 3x)/(x - 2)f⁻¹(x) = (7 - 3x)/(x - 2)5. f(x) = [tex]\sqrt{x - 4}[/tex]
x = [tex]\sqrt{y - 4}[/tex] ⇒ x² = y - 4 ⇒ y = x² + 4f⁻¹(x) = x² + 4(ignore this) question is below.
Given: binom(119, 0.57)
What is the Expected Value?
Answer:
The expected value, or mean, of a binomial distribution, is calculated by multiplying the number of trials by the probability of successes. For example, the expected value of the number of heads in 100 trials of head and tales is 50, or (100 * 0.5)

having trouble with this problem, pls help :/ I know the answer, just not how to get there. (ap calc ab, integrals)
Answer: D) 101
Step-by-step explanation:
By linearity, we can break it up into 2 integrals. The integral and derivative of f easily cancel out
[tex]\int\limits^{10}_{-1} {(2x+0.5f'(x))} \, dx =\int\limits^{10}_{-1} {2x} \, dx +0.5\int\limits^{10}_{-1} {f'(x)} \, dx =x^2|^{^{10}}_{_{-1}}+0.5f(x)|^{^{10}}_{_{-1}}\\=(100-1)+0.5(f(10)-f(-1))=99+0.5(8-4))=101[/tex]
I used the table for values of f(x) at 10 and -1. Wouldn't be surprised if this was part of a series of questions about f because I really can't see how you could use the hypothesis that f is twice differentiable on R. Same for the other table values. I'm curious about how you found the answer. Was it a different way?

Let g(x)= - x^2 + 5x + 2, find and simplify g(-3)
Answer:
g(-3) = -4
Step-by-step explanation:
We are given the following function:
[tex]g(x) = -x^2 + 5x + 2[/tex]
Find and simplify g(-3)
We want to find the value of g when [tex]x = -3[/tex]. So
[tex]g(-3) = (-3)^2 + 5(-3) + 2 = 9 - 15 + 2 = -4[/tex]
g(-3) = -4
