Answer:
ndndjxixzosnxbxbxjxjxkkdns dnxnxjx
Answer:
To find the distance between an two points, you can use the distance formula: sq. root of (x2 - x1)^2 + (y2 - y1)^2
Using the points on the graph; (-2,2) and (-4,-3)
sq. root of (-4 + 2)^2 + (-3 - 2)^2 =
sq. root of (2)^2 + (-5)^2 =
sq. root of 4 + 25 =
sq. root of 29 = 5.38516480713, rounded to the nearest hundred- 5.39
You deposit $6000 in an account earning 8% interest compounded monthly. How much will you have in the account in 15 years?
Answer:
13,200
Step-by-step explanation:
6000/100=60
60x8=480
480x15=7,200
6,000+7,200=13,200
If the initial amount is $6000 , rate of interest 8% then after 15 years the amount willbe $19957.218.
What is compound interest?Compound interest is the interest calculated on the principal and the aggregate interest. It may be copounded annually,semi annually, monthly, bimonthly,etc.
How to calculate interest?We have been given that the deposit is $6000,rate is 8% which is compounded monthly.
So effective rate of interest will be 8/1200=0.0067.
n will be 15*12=180
The sum after 15 years=6000[tex](1+0.0067)^{180}[/tex]
S=6000[tex](1+0.0067)^{180}[/tex]
Take log both sides.
log S=log 6000[tex](1+0.0067)^{180}[/tex]
log S=log 6000+log [tex](1+0.0067)^{180}[/tex]
log S=log 6000+180 log (1.0067)
log S=3.7781+180*0.0029
log S=3.7781+0.522
log S=4.3001
S=AL (4.3001)
S=19957.218
Hence if the initial amount is $6000 , rate of interest 8% then after 15 years the amount willbe $19957.218.

Reason for the answer to b:
It is also an alternate angle. So, b = 35° + 31° = 66°.
what is a palindrome,armstrong,mersenne numbers?
Answer:
A numeric palindrome is a number that remains the same when its digits are reversed.
An Armstrong number of three digits is an integer such that the sum of the cubes of its digits is equal to the number itself.
A Mersenne prime is a prime number that is one less than a power of two.
Step-by-step explanation:
An example of a palindromic number is 16461.
371 is an Armstrong number since 3^3 + 7^3 + 1^3 = 371.
A Mersenne is a prime number of the form Mₙ = 2ⁿ − 1 for some integer n.

Step-by-step explanation:
Set notation is straightforward and just includes putting the lesser and greater signs. For the interval notation, square brackets are for less than and equal or greater than or equal, so I put one for -25. Parentheses are the opposite, only for strict greater or lesser than, so I put a parenthesis.

if de = 6x , EF =4x, and df =10 what is DE
Answer: 6
Step-by-step explanation:
Given DE, EF and DF, we know that DE and EF make up DF. We add DE and EF and set it equal to DF.
6x+4x=10 [add]
10x=10 [divide both sides by 10]
x=1
Now that we know x=1, we can plug that into DE.
6(1)=6
Now, we know that DE is 6.

If x2 + 3x + 7 is divided by x + 2, then what is the remainder?
Answer:
ok but thx for the points
Step-by-step explanation:
The remainder when the polynomial x² + 3x + 7 is divided by x + 2 is 5.
A polynomial is an expression consisting of the operations of addition, subtraction, multiplication of variables.
The remainder theorem states that for a polynomial, f(x) divided by a linear polynomial , x - a, the remainder is equal to f(a).
Given the polynomial; f(x) = x² + 3x + 7, since it is divided by x + 2, hence:
x + 2 = 0
x = -2
f(-2) = (-2)² + 3(-2) + 7 = 5
Hence the remainder when the polynomial x² + 3x + 7 is divided by x + 2 is 5.

To get x, simplify both sides of the inequality.

Now we have to minus(subtract) 46 from both sides.
[tex]\frac{1}{4}x+46-46<21-46\\ =\frac{1}{4}x<-25[/tex]
