Answer: 1.4142
Step-by-step explanation:
Input Data :Point 1 (xA,yA) = (-5, 3) Point 2(xb,yB) = (-4, 2)
Objective : Find the distance between two given points on a line?
Formula :Distance between two points = √(xB-xA)^2+(yB−yA)^2
Solution :
Distance between two points = √(−4−−5)2+(2−3)2= √12+(−1)2= √1+1= √2 = 1.4142
Distance between points (-5, 3) and (-4, 2) is 1.4142

Answer/Step-by-step explanation:
16. 4(x + 3) - 5 < 5x + 7
4x + 12 - 5 < 5x + 7
4x + 7 < 5x + 7
Collect like terms
4x - 5x < 7 - 7
-x < 0
Divide both sides by -1
x > 0
17. 24 > -3x
Divide both sides by -3
24/-3 < -3x/-3
-8 < x
x > -8
18. -5(2x - 6) + 3x < 2(2x + 1) - 11x
-10x + 30 + 3x < 4x + 2 - 11x
Add like terms
-7x + 30 < -7x + 2
-7x + 7x < -30 + 2
0 < -28
All equilateral triangles are isosceles.
A. True
B. False
Answer:
A. True
Step-by-step explanation:
This statement is true. The definition of an isosceles triangle is a triangle with at least two congruent sides. Since all equilateral triangles have three congruent sides, they fit the definition of an isosceles triangle.

What is the inverse of f(x) = 2x2 -4?
Need answers asap
Answer:
Step-by-step explanation:
The function doesnt have an inverse. In order for a function to actually have an inverse, it has to pass the horizontal line test. The function above has repeating y-values because of the x^2.
With all this said, you can still find the inverse of the function as long as you restrict the domain (x-values) for the function. So, you cant consider the negative x-values.
First, replace f(x) with y and then switch the x and y variables
[tex]x=2y^2-4[/tex]
Then solve for y by adding 4 to both sides, dividing by 2, and finally taking the square root.
[tex]x+4=2y^2[/tex]
[tex]\frac{x+4}{2} =y^2[/tex]
[tex]\sqrt{\frac{x+4}{2} }=y[/tex]

A chain lying on the ground is 10 m long and its mass is 60 kg. How much work (in J) is required to raise one end of the chain to a height of 4 m?
Answer:
Approximately [tex]4.70 \times 10^{2}\; \rm J[/tex], assuming that [tex]g = 9.81\; \rm m \cdot s^{-2}[/tex].
Step-by-step explanation:
When the force [tex]F[/tex] is constant, moving by [tex]\Delta x[/tex] in the direction of the force would do a work of [tex]F \cdot \Delta x[/tex].
However, in this example, as an increasing portion of the chain gets lifted up, the force lifting the chain would increase in size. Hence, apply the integral form of this equation.
Let [tex]F(x)[/tex] denote the force required to lift the chain when the height above the ground is [tex]x[/tex] meters. At that moment, exactly [tex](x / 10)[/tex] of the chain would be above the ground. The mass of that much of the chain would be [tex](x / 10)\![/tex] the mass of the whole chain.
[tex]\begin{aligned}F(x) &= m(x) \cdot g \\ &= 60 \cdot \frac{x}{10} \cdot g = 6\, g\, x\end{aligned}[/tex].
Integrate with respect to [tex]x[/tex]:
[tex]\begin{aligned}\int \limits_{0}^{4} F(x) \cdot {\rm d} x &= \int \limits_{0}^{4} 6\, g\, x \cdot {\rm d} x \\ &= \left[(3\, g)\, x^{2}\right]_{x=0}^{x=4}\\ &= 48\, g \approx 4.7 \times 10^{2} \end{aligned}[/tex].
In other words, it would take approximately [tex]4.7 \times 10^{2}\; \rm J[/tex] of energy to raise one end of the chain to that height of [tex]4\; \rm m[/tex].

Recall that an American Roulette wheel has 38 possible outcomes, 18 black, 18 red and 2 green. The numbers go from 1 to 36, and the green outcomes are numbered 0 and 00. Someone places 10 bets on "1st 12", that is, that person wins if the outcome is any number between 1 and 12, included. 1. (2pts) What is the probability of losing a ’1st 12’ bet on a single spin? 2. (3pts) What is the probability of winning 7 out of the 10 total bets?
Answer:
American Roulette
1. The probability of losing a ’1st 12’ bet on a single spin is:
= 0.67
2. The probability of winning 7 out of the 10 total bets is:
= 0.23
Step-by-step explanation:
Possible outcomes in an American Roulette wheel = 38
Make-up of the outcomes = 18 black, 18 red and 2 green
Green outcomes are numbered 0 and 00
Number of wins for this person = 12
Probability of winning = 0.33 (12/36)
Number of possible losses for this person = 24
Probability of losing = 0.67 (24/36)
1. The probability of losing a '1st 12' bet on a single spin is:
= (36 - 12)/36
= 0.67
2. The probability of winning 7 out of the 10 total bets is:
Probability of winning = 12/36 * 7/10
= 0.23

Answer:
B and C
Step-by-step explanation:
Minimum and Maximum points occur when the gradient of the function is equal to 0. Graphically this looks like a bend such that the function dips from decreasing to increasing (the gradient goes form being negative to positive) and vice versa.
A minimum point occurs where all the nearby values are higher than that of the point in question.
A maximum point occurs where all the nearby points are lower than the point in question.
By looking at the graph, there is a maximum point around (4.5, 1.5) which is consistent with B but not A (since A talks about a minimum point)
By looking at the graph, there is a minimum point around (0.5, 1.5) which is consistent with C.

Answer:
55°
Step-by-step explanation:
A couple of auxiliary lines can be helpful.
We see that 45° is an exterior angle to the bottom triangle, which has remote interior angles that must total 45°. This means the interior angle at bottom left must be 45° -15° = 30°.
The upper right interior angle is alternate to that, so is the same measure. The exterior angle x to the upper triangle is then the sum of the remote interior angles:
x = 25° +30°
x = 55°

The seats are divided into 40 sections. If hats are to be given in only 5 sections, what is the probability of a guest sitting in a winning section? Record your answer as a fraction in simplest form.
Answer:
P=(Probablility of a guest sitting in a section that gets a hat) =number of ways it can happen/total number of outcomes. =5/40= 1/8
Step-by-step explanation:
The probability of a guest sitting in a winning section is 1/8.
What is probability?Probability is the chance of occurrence of a certain event out of the total no. of events that can occur in a given context.
Given, The seats are divided into 40 sections and hats are to be given in only 5 sections.
Here, N(S) = 40 and N(H) = 5.
Therefore, We know, P(H) = N(H)/N(S).
P(H) = 5/40.
P(H) = 1/8.

A term used in probability theory to describe the likelihood that one event will follow another given the occurrence of another event.
