Given that point P partitions AB into a ratio of 3:2, and A is found at (-4, -3) and P is found at (3, 6), find the coordinates for B.
Answer:
The coordinates of B are (7.67,12)
Step-by-step explanation:
Let the coordinates of B are (h,k).
Now, point P(3,6) partitions AB into a ratio of 3 : 2 and A is found at (-4,-3).
We have to find B(h,k).
Now, from the formula of coordinate geometry we have,
[tex]3 = \frac{2(- 4) + 3h}{3 + 2}[/tex]
⇒ 3h - 8 = 15
⇒ 3h = 23
⇒ h = 7.67
And, [tex]6 = \frac{2(- 3) + 3k}{2 + 3}[/tex]
⇒ 3k - 6 = 30
⇒ 3k = 36
⇒ k = 12
Therefore, the coordinates of B are (7.67,12) (Answer)

Allie and Sarah decided that they want to purchase renters insurance for the apartment they share. They made a list of all of the items to be covered by the insurance policy, along with their estimated values. If the items to be covered total more than $3000, the insurance company charges an annual premium of 23% of the total value of the items. If the items to be covered total $3000 or less, the insurance company charges an annual premium of 20% of the total value of the items. Using the list of items Allie and Sarah provided, determine their monthly renters insurance premium. Allie's Stuff Sarah's Stuff TV ($250) Stereo ($75) Stereo ($150) Bicycle ($250) CD's ($225) CD's ($130) DVD's ($385) DVD's ($300) Bicycle ($400) IPOD ($80) Microwave ($30) Computer ($675) Laptop Computer ($950) a. $65.00 b. $74.75 c. $325.00 d. $780.00
Answer:
The answer is b. $ 74.75
Step-by-step explanation:
First, we need to gather the data from the question.Data:
Let x be the value of items to be insured.
1. if the items are more than $ 3 000 it means that x is greater than $ 3000 and the annual premium will be 23 % of the total value.
2. if the items are less or equal to $ 3 000, it means that x ≤ $ 3 000 ( in other words, x is less than or equal to $ 3 000)
Second, we find the total worth of all the items. Adding up all the values gives $ 3900 which is more than $ 3 000. Therefore, rule 1 applies.The annual premium for the goods will be:
annual premium = 23 % × $ 3900
= $ 897
However, the premium is supposed to be paid monthly. Divide the total premium by 12 to get:
$ 897/12 = $ 74.75
This is option c.

David bought 3 dvds and 4 books for $40 at a yard sale. Anna bought 1 dvd and 6 books for $18. How much did each dvd and book cost?
Answer: d=$12, b=$1
d represents DVDs
b represets books
Step-by-step explanation:
Whenever you have 2 examples of 2 different things (such as books and dvds), make a systems of equations.
Step 1: Write a system of equations
3d+4b= 40
d+6b= 18
Step 2: Eliminate any letter. I'll just choose d.
To elimiate d, you have to make them both equal to the biggest d variable. In other words, make both d terms equal to 3d. To do this, miultiply the 2nd equation by 3, and keep the 1st one the same.
3d+4b=40
3d+18b= 54
Now, elimiate d, by doing 3d-3d= 0. Now use subtraction to solve for b since we used this to get 3 and 3 to 0.
4b-18b=40-54
-14b= -14
b= -14÷-14
b= 1
Each book costs 1 dollar.
Step 3: Plug in b=1 to find how much each dvd costs (plug into any equation)
3d+4b=40
3d+4(1)=40
3d+4=40
3d=40-4
3d=36
d=36÷3
d=12
Each dvd is $12
Step 4: Checks--plug d=12 and b=1 into any equation
3d+4b=40
3(12)+4(1)=40
36+4=40
40=40
It's correct ✅

A radio wave has a wavelength of 357 m. What is this wavelength in scientific
notation?
Step-by-step explanation:
[tex]357 \: m = 3.57 \times {10}^{2} \: m[/tex]
The wavelength of the radio wave in scientific notation is 3.57 x 10^2 m.
Explanation:The wavelength of a radio wave is given as 357 m. Since this is already a simple number, converting it to scientific notation would be 3.57 x 102 m. Here, '3.57' is the significant part of the number (the significand) and '2' is the power to which 10 is raised (the exponent). In scientific notation, we aim to express numbers between 1 (inclusive) and 10 (exclusive).
Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10.

Find the value of x in the isoceles triangle shown below.
PLEASE HELPPPPP
Answer:
The measure of 'x' is 6 units.
Step-by-step explanation:
Given:
An isosceles triangle.
The two equal arms length = [tex]\sqrt{13}[/tex]
Measure of the altitude = [tex]2[/tex]
Note:The altitude to the base of an isosceles triangle bisects the base.
The altitude also forms 90 degree at the base.
So, the base length can also be seen as 'x' which we can also be written as [tex]x=\frac{x}{2} +\frac{x}{2}[/tex]
And [tex]\frac{x}{2}[/tex] is a part of the right angled triangle.
Where hypotenuse = [tex]\sqrt{13}[/tex]
Perpendicular length =[tex]2[/tex]
Base length = [tex]\frac{x}{2}[/tex]
Now,
From Pythagoras formula we know that:
[tex](hypotenuse)^2 =(perpendicular)^2+ (base)^2[/tex]
Plugging the values:
⇒ [tex](hypotenuse)^2 - (perpendicular)^2 = (base)^2[/tex]
⇒ [tex]\sqrt{ (hypotenuse)^2 - (perpendicular)^2} = (base)[/tex]
⇒ [tex]\sqrt{(\sqrt{13})^2-(2)^2} =\frac{x}{2}[/tex]
⇒ [tex]\sqrt{13-4}=\frac{x}{2}[/tex]
⇒ [tex]\sqrt{9} =\frac{x}{2}[/tex]
⇒ [tex]3=\frac{x}{2}[/tex]
⇒ [tex]3\times 2=x[/tex]
⇒ [tex]6 = x[/tex]
So the value of base 'x' = 6 units.

67% of U.S. adults have very little confidence in newspapers. You randomly select 10 U.S. adults. Find the probability that the number of U.S. adults who have very little confidence in newspapers is (a) exactly five, (b) at least six, and (c) less than four.
To calculate probabilities in a binomial experiment, use the binomial probability formula. For exactly five successes, use P(X=k) = C(n,k) * p^k * (1-p)^(n-k). For at least six successes, sum the probabilities of getting exactly six to ten successes. For less than four successes, sum the probabilities of getting zero to three successes.
Explanation:To find the probability of selecting a certain number of U.S. adults with very little confidence in newspapers, we can use the binomial probability formula. For (a) exactly five, we can calculate the probability using the formula P(X=k) = C(n,k) * p^k * (1-p)^(n-k), where n is the number of trials (10), k is the desired number of successes (5), p is the probability of success (0.67), and C(n,k) is the number of combinations. Plugging in the values, we find P(X=5) = C(10,5) * (0.67)^5 * (1-0.67)^(10-5).
For (b) at least six, we need to calculate the probability of getting six or more successes. We can find this by summing the probabilities of getting exactly six, seven, eight, nine, and ten successes: P(X>=6) = P(X=6) + P(X=7) + P(X=8) + P(X=9) + P(X=10).
For (c) less than four, we need to calculate the probabilities of getting zero, one, two, or three successes: P(X<4) = P(X=0) + P(X=1) + P(X=2) + P(X=3).

Solve: x + 1.5= 5.7
How do I solve this?
Answer:
4.2
Step-by-step explanation:
5.7-1.5=4.2
Answer: x = 4.2
Explanation: If we're asked to solve for x in the equation x + 1.5 = 7.5, what we're really being asked to do is get x by itself on one side of the equation.
So if we take a look at the left side of our equation, notice that 1.5 is being added to x so in order to get x by itself, we must subtract 1.5 from the left side of the equation. Now remember your first rule of solving equations. If we subtract 1.5 from the left side of the equation, we must also subtract 1.5 from the right side of the equation.
So on the left side our +1.5 and -1.5 cancel out and we're simply left with x. On the right side of the equation,
5.7 - 1.5 simplifies to 4.2 so our answer is x = 4.2.
The nice thing about solving equations is that you can always check your answer by plugging it back in to the original equation.
So here, we're gonna plug a 4.2 back in for x in the original equation and we get (4.2) + 1.5 = 5.7.
Since 4.2 + 1.5 = 5.7 is a true statement, our answer checks and we know that it's right.
What is the domain of the function y = StartRoot x EndRoot + 4
Answer:
third option !!!! 0 less-than-or-equal-to x less-than infinity
Step-by-step explanation:
The domain of the function y = √x + 4 is all real numbers x such that x ≥ 0, because the square root of a negative number is not a real number in the set of real numbers.
Explanation:The given function is y= x +4. The square root function x is defined only for non-negative values of x. This is because the square root of a negative number is not a real number in the real number system.
Therefore, for the given function to be defined, the expression inside the square root (x) must be greater than or equal to zero. Mathematically, this condition is expressed as:x≥0
This inequality ensures that the square root is always defined for any real number x in the domain of the function.
So, the domain of the function y= x +4 is all real numbers x such that x≥0. In interval notation, this can be expressed as [0,∞).

a boat costs $16600 and decreased in value by 14% per year. How much will the boat be worth after 11 years?
The worth of boat after 11 years is $ 3159.3013
Solution:
Given that,
Boat costs $16600 and decreased in value by 14% per year
To find: Worth of boat after 11 years
The formula for decreasing function is given as:
[tex]y = a(1-r)^t[/tex]
Where,
y is the value after "t" years
t is the number of years
a is the initial value
r is decreasing rate in decimal
From given,
a = 16600
t = 11
[tex]r = 14 \% = \frac{14}{100} = 0.14[/tex]
Substituting the values we get,
[tex]y = 16600(1-0.14)^{11}\\\\y = 16600(0.86)^{11}\\\\y = 16600 \times 0.1903\\\\y = 3159.3013[/tex]
Thus the worth of boat after 11 years is $ 3159.3013
solve the system of equations by graphing. x+y=-9 4x+y=-19
For this case we have the following system of equations:
[tex]x + y = -9\\4x + y = -19[/tex]
We multiply the first equation by -4:
[tex]-4x-4y = 36[/tex]
We have the following equivalent system of equations:
[tex]-4x-4y = 36\\4x + y = -19[/tex]
We add the equations:
[tex]-4x + 4x-4y + y = 36-19\\-3y = 17\\y = - \frac {17} {3}[/tex]
We find the value of the variable "x":
[tex]x = -9-yx = -9 - (- \frac {17} {3})\\x = -9 + \frac {17} {3}\\x = \frac {-27 + 17} {3}\\x = - \frac {10} {3}[/tex]
Thus, the solution of the system is:
