Answer:
Circumference of circle = π x Diameter of circle
Step-by-step explanation:
If you know the diameter or radius of a circle, you can work out the circumference. To begin with, remember that pi is an irrational number written with the symbol π. π is roughly equal to 3.14. The formula for working out the circumference of a circle is: Circumference of circle = π x Diameter of circle
Santiago has $6000 spread across his 3 accounts. He has a checking account which pays 2% interest, a savings account that pays 5% interest, and a money market account which pays 7% interest. At the end of 1 year, he earned a total of $355 in interest. If he put $2300 less in his savings accout than his money market account. Find how much money Santiago put into each account
Answer:
Santiago put $700 into a checking account, $1,500 into a savings account and $3,800 into a money market account.
Step-by-step explanation:
From the information given, you can write the following equations:
x+y+z=6000 (1)
0.02x+0.05y+0.07z=355 (2)
y=z-2300 (3)
First, you have to replace (3) in (1) and (2):
x+z-2300+z=6000
x+2z=8300 (4)
0.02x+0.05(z-2300)+0.07z=355
0.02x+0.05z-115+0.07z=355
0.02x+0.12z=470 (5)
Now, you have 2 equations:
x+2z=8300 (4)
0.02x+0.12z=470 (5)
Then, you can solve for x in (4):
x=8300-2z (6)
After this, you have to replace (6) in (5):
0.02(8300-2z)+0.12z=470
166-0.04z+0.12z=470
0.08z=304
z=3800
Now, you can replace z in (6) to find x:
x=8300-2(3800)
x=700
Finally, you can replace z in (3) to find y:
y=3800-2300
y=1500
According to this, the answer is that Santiago put $700 into a checking account, $1,500 into a savings account and $3,800 into a money market account.

two irrational numbers between 0 and 1
Answer:
1/3 and 2/3
Step-by-step explanation:
1/3= 0.33333333 (which is an irrational number)
2/3= 0.666666 (which is also an irrational number)
An irrational number is where the decimal never ends.
So 1/3 and 2/3 are irrational numbers.

Now, what are the five factors of 16?
Type the factors in increasing order.
Given parameters:
The value given is 16
Problem is to find the factors of 16
A factor is any number that divides another number into equal parts without any remainder.
For 16, the factors are:
1 , 2 , 4 , 8 and 16
These numbers will divide 16 into equal parts. A number is a factor of itself.
1 is a factor of any number.
So, the five factors of 16 are 1, 2, 4, 8 and 16

How does scientific notations work?The number is written in the form [tex]a \times 10^b[/tex] where we have [tex]1 \leq a < 10[/tex]
The number b shows the order, which is the most important figure for which scientific notation is used. It tells us how much order large or small a value is in powers of 10. We can for a time, ignore the value of 'a' for two comparable quantities and only compare their orders(this type of comparison is useful when difference is too big, like size of human to size of a star etc sort of comparisons).
When we multiply numbers in scientific notation, then
1.466 x 5.02 =7.56932
Then we add the exponents on the powers of 10 as;
10^(-8+5) = 10^(-3)
The result is 7.56932 x 10^-3
Using a calculator, we get 0.00735932, this is not in scientific notation.
0.00735932 changed to scientific notation
Now Move the decimal until a nonzero digit is to the left of the decimal
7.35932
Which that means our exponent is -3
7.35932 x 10^-3

What is the 96th term of -16,-28,-40 hi
Answer:
Tn = a + (n - 1) d
where a = first term
n = number of the member of the sequence
d = common difference
a = -16
n = 96
d = second term - first term or
third term - second term
= -28 - (-16) = -28 + 16 = -12 or
= -40 - (-28) = -40 + 28 = -12
d = -12
Tn = a + (n - 1) d
= -16 + (96 - 1) -12
= -16 + (95) -12
= -16 + (-1140)
= -16 - 1140 = -1156
A manufacturer produces dice in many different sizes. If the side length of the dice is double, then the volume of the larger dice is how many time the volume of the smaller dice?
Answer:
Here you are...
Step-by-step explanation:
If you double one of the dimensions, say change one side from 2 to 4 it doubles the volume. if you were to do this to any side, say double it, it would double the volume. ... It will make the volume 4 times as much also. the volume would go from 30 to 120.

Fill in the blanks concerning the following quadratic function: f(x)=−x2−4x+5
.
The leading coefficient of f(x)
is
Answer:
Step-by-step explanation:
Given quadratic function is,
f(x) = -x² - 4x + 5
Leading term of the quadratic function is 'x²'
Coefficient of this leading term is (-1).
Now we will convert this standard equation into vertex form,
f(x) = -x² - 4x + 5
= -(x² + 4x) + 5
= -[x² + 2(2x) + 4 - 4] + 5
= -[x² + 2(2x) + 2²] + 4 + 5
= -(x + 2)²+ 9
f(x) = -(x + 2)² + 9
Since, coefficient of the leading term is negative the parabola will open downwards.
Vertex form of the function is given by,
g(x) = -(x - h)² + k
(h, k) is the vertex.
By comparing the equation of the function 'g' with the function 'f',
(-2, 9) will be the vertex of the function which is the maximum point of the function.
