Step-by-step explanation:
a quadritilateral always has 4 sides, but it dpesnt HAVE to be a square
a parrellelogram can be any shap as long as its parrelel
a rhombus is always a square, becuase if you turn it around... VIOLA! you get a square.
Answer:
In two years, it will get <em>$57.24</em> interest.
Step-by-step explanation:
For this case, the first thing to do is find the area of the trapezoid.
We have then:
Where,
b1: b2: Trapezoid bases
h: height of the trapezoid
Substituting values we have:
Then, the cost per square foot is given by:
Answer:
The new carpet for the room will cost:
C = 1072.5 $
3.14 x 10⁻³ has the value 0.00314
The exponent tells us the number of times the decimal has to move. The sign of the exponent tells us the direction of the movement of the decimal.
The negative sign of the exponent means that the decimal has to move to the right.
From 0.00314, decimal move to the right 0003.14
If the decimal is positive, it means that the decimal point moved to the left of the number.
3.14 x 10³ in expanded form is 3140
From 3140. decimal move to the left 3.140
To answer this, you need to know the slope point formula:
y - y1 = m (x - x1)
In this case, (1, -4) represent y1 and x1. m is equal to the slope, which is -3.
y - (-4) = -3 (x - 1)
y + 4 = -3x + 3
y = -3x + 3
-4
y = -3x - 1
Answer: y = -3x -1
