How do I graph the parabola?
scoundrel [369]
First of all, find a program or a calculator that will give you the answer. Then you'll know how to make your table. I recommend Desmos. I have inserted the final graph for you.

Make up a table for this graph. Put the lowest point as the central entry in your graph.

x      y
-4
-3
-2
-1
0
Now fill in the y values. 

x       y
-4      1
-3       -3.5
-2        -5
-1       -3.5
0         1

You can use the outline of the parabola and then mark the outline with the points in the table.

Use inductive reasoning to find the next term in the sequence 0, 1, 1, 2, 3, 5, 8 …<br>Answer is 13
expeople1 [14]

Answer:

13

Step-by-step explanation:

Look carefully:  you'll see that each new term is the sum of the previous two terms.  The 3rd term is 0 + 1, or 1.  The 4th term is 1 + 1, or 2.  The 8th term is the sum of 5 and 8, or 13.

A parallelogram has base (2x - 1) metres and height (4x - 7) metres.
Jobisdone [24]

Answer:

0.4069 ; 1.843

Step-by-step explanation:

Given:

Base of parallelogram, b = (2x - 1)

Height = (4x - 7)

Area = 1

Area of parallelogram = Base * height

Area of parallelogram = (2x - 1) * (4x - 7)

(2x - 1) * (4x - 7) = 1

8x² - 14x - 4x + 7 = 1

8x² - 18x + 7 - 1 = 0

8x² - 18x + 6 = 0

Divide through by 2

4x² - 9x + 3 = 0

Solving the quadratic equation :

Using the formula

-b ± √(b² - 4ac) / 2a

a = 4 ; b = - 9 ; c = 3

Plugging in the values :

-(-9) ± √((-9)² - 4(4)(3)) / 2(4)

9 ± √(81 - 48) / 8

9 ± √33 / 8

(9 ± 5.7445626) / 8

(9 - 5.7445626) / 8) = 0.4069

(9 + 5.7445626) / 8 = 1.843
