The 875 times smaller is 4 x 10−7 than 3.5 x 10−4.

<h3>What is the arithmetic operator?</h3>

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

Summation = addition of two or more numbers or variable

For example = 2 + 8 + 9

Subtraction = Minus of any two or more numbers with each other called subtraction.

For example = 4 - 8

Division = divide any two numbers or variable called division.

For example 4/8

Multiplication = to multiply any two or more numbers or variables called multiplication.

For example 5 × 7.

Given the two quantities 4 x 10−7 and 3.5 x 10−4

Now, if we divide this then

⇒ (3.5 x 10−4)/(4 x 10−7)

⇒ (35/40) × 10³

⇒ 875

Hence "The 875 times smaller is 4 x 10−7 than 3.5 x 10−4".

Which statements correctly describe the association between the variables A and B?
gulaghasi [49]

Since it is not perfectly straight it’s not linear so

*nonlinear association

The line goes down not up so it’s

*negative association

If your teacher wants to count the point outside of the regular line it would be no association

The two that most fit this graph are nonlinear and negative association

Determine the area of each polygon below <br><br> Help me please
julia-pushkina [17]
9) Separate the polygon into 2 shapes (a rectangle and triangle). Then plug in the formula for those 2 shapes separately and add the 2 areas.
First, the triangle's area = bh x 1/2 or bh/2.
b=5 and h=5, so 5x5/2 or 25/2 = 12.5.
Next, solve the area for the rectangle(lw=A). l=5 and 2=8, so 5x8=40.
Add 40 +12.5 = 52.5cm^2 (always include units).

10) It is similar to the last problem. You will separate the polygon into 2 shapes (a circle and a square), but this time you will subtract the area of the sector formed from the circle (draw a dotted line where the circle would be formed in the square).
So, the area of the square is 2x2=4ft^2. 
area of a circle is (pi)r2 or (pi)2^2= 4pi or about 12.5ft^2.
4+12.5 = 16.5 ft^2.
Now, the area of the sector must be subtracted from the combination of the 2 areas found above.
The area of a sector is 2(pi)r x (C/360).
The angle is given as 90°, the radius is 2 ft. Now plug these into the equation.
2(pi)(2)x(90/360) = 3.14ft^2.
16.5-3.14= 13.4 ft^2.

Rewrite the following expression without using absolute value. lz-6l-lz-5l if z&lt;5
MA_775_DIABLO [31]

The expression without using absolute value is 2z - 11

<h3>Absolute value of a function</h3>

Given the expression with absolute value expressed as:

lz-6l-lz-5l

Since absolute function can both be negative or positive, hence;

lz-6l-lz-5l = z - 6 - -(z - 5)

lz-6l-lz-5l = z-6-(-z+5)

lz-6l-lz-5l = z - 6 + z - 5

lz-6l-lz-5l = 2z - 11

Hence the expression without using absolute value is 2z - 11
