Answer:
-14
Step-by-step explanation:
Okay first we must simplify the expression.
so this:(3x^2 + x-2)(x - 5)
becomes this:3x^3-14x^2-7x+10
then we look at the coefficient of x^2 and we see that it's -14
Answer: 31.43 cm
Step-by-step explanation:
The length of an arc is calculated using the formula:
X 2
r
where : theta is the angle in degree
r = radius
If the angle is given in Radian , the length can be calculated using the formula:
L = r∅
Since , the angle is given in degree , we will use the first formula.
L = X 2r
L = 
X 2 X π X 15
L = 
X 2 X 
X 15
L = 
L = 31.42857143
L ≈ 31.43 cm
Answer:
<h2> 934boxes</h2><h2> 4 trips</h2>
Step-by-step explanation:
Given the total number of books 42,000
Ok, firstly let us calculate the number of boxes required, given that a box can contain 45 books
number of boxes= 42,000/45
number of boxes=933.3 boxes
approximately 934boxes
Also, given that the truck can carry online 250 boxes in one trip
then it must make 934/250= 3.7 trips
approximately the truck will make 4 trips to carry all the boxes
Answer: The length of minor arc AB = 12.56 units.
Step-by-step explanation: The circle x has its circumference given as 2Pi x r.
A fraction of the circle is given as O/360,
Where O is the angle subtended at the center of the arc AB.
The length of an arc can be calculated by the formula;
Length of arc = O/360 x (2Pi x r)
Length of arc = 60/360 x (2 x 3.14 x 12)
Length of arc = 1/6 x (6.28 x 12)
Length of arc = 12.56 units.
Therefore the length of minor arc AB = 12.56 units
