Answer:
<h3>#1</h3>
- x² - 9 = 0
- x² = 9
- x = ± √9
- x = ± 3
Yes, -3 and 3 are zeroes of this polynomial
<h3>#2</h3>
<em>See attached graphs</em>
Zero's of a polynomial are the intersection of the graph with the x-axis.
They include coordinates as (x, 0), so the x-coordinates are zero's.
The attached shows the zero's.
<h3>#3</h3>
<em>See attached graphs</em>
Zero's of each polynomial are reflected in the graphs.
- () y = x² - x - 6 has zeros x = -2 and x = 3
- (ii) y = 6 - x - x² has zero's x = -3, x = 2
Answer:
No it is not a reasonable scale. She should use 1 inch= 6 inches.
Step-by-step explanation:
The width of the drawing is 48 inches, dividing it by 4 inches gives 48/4=12 inches.
This is exactly the width of her paper. Which means the drawing will get to the edge.
The height of the drawing is 120 inches,divide by 4inches you get: 120/4=30 inches. The height of paper is 24 inches. Which means her paper is too small to accommodate the height of the drawing. The preferred scale would be 1 inch=6inches.
The inequality that is true is 7π > 21
<h3>How to determine the inequality that is true?</h3>
To do this, we simply test the given inequalities (starting from the first)
The first inequality is represented as
7π > 21
Divide both sides of the inequality by 7
So, we have:
7π/7 > 21/7
Evaluate the quotient of 21 and 7
So, we have:
7π/7 > 3
Evaluate the quotient of 7π and 7
So, we have:
π > 3
The above inequality is true.
This is so because π = 3.14 and 3.14 > 3
Hence, the inequality that is true is 7π > 21

Answer:
15
Step-by-step explanation:
Given that a1 = 6
an = 3 + 2(an-1),
Substitute n = 2 into the formula
a2 = 3 + 2(a1)
a2 = 3 + 2(6)
a2 = 3+12
a2 = 15
Hence the second term of the sequence is 15
