x^2 - 8x + 5 = 0
(a) find the value of the discriminant
(b) state the number and type of the roots (2 real, 2 imaginary/complex or 1 real).
√44
2 Real Roots
Step-by-step explanation:Looking at the image attached, the discriminant is the value under the square root.
In the equation given:
a = 1
b = -8
c = 5
The discriminant is therefore:
√(b²- 4ac) = √(-8²- (4*1*5)) = √(64-20) = √44
√44 is a positive number. Because it is positive, there must be 2 real roots.
If it were negative, there would be 2 imaginary roots.
If it were zero, there would be 1 real root.

Answer:
x = [tex]\sqrt{17}[/tex]
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides , that is
x² = 4² + 1² = 16 + 1 = 17 ( take square root of both sides )
x = [tex]\sqrt{17}[/tex]
Answer:
x = 4.12
Step-by-step explanation:
Remark
Use the Pythagarian Theorem a^ + b^2 = c^2
a = 1
b = 4
c = ?
Solution
1^2 + 4^2 = c^2 Expand
1 + 16 = c^2 Combine
c^2 = 17 Take the square root of both sides
sqrt(c^2) = sqrt(17)
c = 4.12 Answer

Answer:
x = 20Step-by-step explanation:
from how the sides are marked it is an equilateral triangle, to see it does not seem. assuming that it is equilateral it has 3 angles of 60 ° for which 4x - 20 = 60
4x - 20 = 60
4x = 80
x = 80 : 4
x = 20
-------------------
4 * 20 - 20 = 60°

Step-by-step explanation:
Tonis cat weighs 2,240 grams. How many kilograms does her cat weigh? Use 100 grams = 1 kilograms to convert the rates.
Answer: 2.24
Step-by-step explanation:
Firstly, one kilo is 1000 grams, not 100. 2240/1000=2.24
Toni's cat weighs 22.4 kilograms.
To convert grams to kilograms, we divide the weight in grams by the conversion rate of 100 grams per 1 kilogram.
For Toni's cat weighing 2,240 grams, we divide 2,240 by 100 to get the weight in kilograms.
2,240 grams / 100 grams per kilogram = 22.4 kilograms.
Therefore, Toni's cat weighs 22.4 kilograms.
The conversion rate of 100 grams to 1 kilogram allows us to easily convert weights from smaller units (grams) to larger units (kilograms). In this case, dividing the weight in grams by 100 gives us the weight in kilograms, providing a simple way to convert between the two units.

Use your function rule to complete each statement. Type the correct answer in each box. Use numerals instead of words.
After 3.5 days, the height of the plant is ____ centimeters.
The height of the plant is 6.25 centimeters after ____ days.
Hii!
After 3.5 days, the height of the plant is 5.75 centimeters.
h = 0.5(3.5) + 4
h = 1.75 + 4
height = 5.75 cm after 3.5 days.
The height of the plant is 6.25 centimeters after 4.5 days.
6.25 = 0.5d + 4
6.25 - 4 = 0.5d - 4
2.25 = 0.5d
2.25/0.5 = 0.5d/0.5
4.5 = d
days = 4.5
Thus, the height of the plant is 6.25 centimeters after 4.5 days.
After 3.5 days, the height of the plant is 5.75 centimeters and the height of the plant is 6.25 centimeters after 4.5 days.
What is a straight line?A straight line is a combination of endless points joined on both sides of the point.
The slope 'm' of any straight line is given by:
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
The equation of the line is:
h = 0.5d + 4
After rewriting the function:
f(x) = 0.5x + 4
Plug x = 0
f(0) = 4 cm
f(1) = 4.5 cm
f(2) = 5 cm
f(3) = 5.5 cm
f(4) = 6 cm
f(5) = 6.5 cm
Plug x = 3.5 days
f(3.5) = 5.75 cm
Plug f(x) = 6.25
6.25 = 0.5x + 4
2.25 = 0.5x
x = 4.5 days
Thus, after 3.5 days, the height of the plant is 5.75 centimeters and the height of the plant is 6.25 centimeters after 4.5 days.
