Step-by-step explanation:
The angle where the shadow ends is
The distance from the tree to the angle of end shadow equal (60-20)=40ft
So the tall of tree is
Answer:
x=-4
y= 2
z= -4/3
Step-by-step explanation:
x= -4 (directly)
-2y = -4
or, y = -4/-2
y =2
3z= -4
z= -4/3
Answer:
a) yes b) no c) no
Step-by-step explanation:
In order to know this, remember something: to do the division between a number and a rational number like this and with zero to the left, the best way to solve them is converting these number to a natural number.
To do that, you only need to multiply the number by 10, 100, 1000, depending of how many decimals it have.
In case a) 0.05 has two decimals, therefore we multiply by 100:
0.05 * 100 = 5
However, when you do that, you have to do the same thing with the number in the dividend, in this case, 1.4:
1.4 * 100 = 140
So we can conclude that 1.4 you have to add a zero to do the division.
Case b) and c) do not apply, in both cases we multiply by 10 and we get this:
25.2 and 6,
26.1 and 3.
The expression given as x³ + 4x² - 3x + 1 cannot be factored
<h3>How to determine the factor the
expression?</h3>
From the question, we have the following expression that can be used in our computation:
x³ + 4x² - 3x + 1
The above expression is a polynomial expression
The number of terms in the expression is 4
This means that, when the terms are grouped in twos, we should be above to factor the expression
[x³ + 4x²] - [3x - 1]
However, this is not the case because [x³ + 4x²] and [3x - 1] or any other combination do not have common factor
So, it is better to leave the expression without changing its form
Hence. x³ + 4x² - 3x + 1 cannot be further factored
