Step-by-step explanation:
x2 + bx +5 = 0,
where a,b and c are rational numbers.
Also it is given that the quadratic has 2 distinct zeros and one of it's zero is irrational.
We know that if it has a one irrational zero, the conjugated couple of the one zero is also a null with the same polynomial balance for a polynomial equation with rational coefficients." Therefore, in this case it is a quadratic equation, one is null and irrational; thus, the other zero is irrational.

What is the degree of 25 = 2.03 + 2.0 4x + 1
Answer:
Fraction: x = 2197/204
Decimal: 10.76960
Step-by-step explanation:
Switch Sides: 2.03 +2.04x + 1=25
Group Like Terms: 2.04x + 2.03 + 1 =25
Add The Numbers 2.03 + 1 = 3.03: 2.04x + 3.03 = 25
Multiply Both Sides By 100: 2.04 * 100 + 3.03 * 100 = 25 * 100
Clarify: 204x+303=2500
Subtract 303 From Both Sides: 204x + 303 - 303= 2500 - 303
Divide Both Sides By 204: 204x/ 204, 2197/204
Simplify: x = 2197/204

Tim played 20 games of draughts.
He won 16 of these games.
a) What fraction of the games did he win?
Give your answer in its simplest form.
Answer:
4/5
Step-by-step explanation:
Played 20 games. Won 16. Both numbers have a 4 in common. divide 16 by 4.. which is 4. Divide 20 by 4... which is 5. That means Tim won 4/5 of the games played.
Answer :4/5
Step-by-step explanation:
Because we write 16/20 and simplify it by 4 and thats the simplest form
Caitlin drew a circle and labeled the circle S. The diameter of Caitlin’s circle is 12 m. Which of the following best represents the area of Caitlin’s circle?
A. 452 m^2
B. 38 m^2
C. 113 m^2
D. 75 m^2
Answer:
C
Step-by-step explanation:
Radius: 12 / 2 = 6 m
Area: 6^2 x pi = 113 m^2
Answer:
c
Step-by-step explanation:
area = π · r²
to change the diameter to radius you just divide by 2
12/2=6 so the radius is 6
then we just plug 6 into r for the circle are formula
6²=36
36x3.14=113.04 so her best answer choice is c
HELP SOMEONE ANWSER PLEASE
Answer:
A = 40 cm²
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂)
where h is the perpendicular height and b₁, b₂ the parallel bases
Here h = 5, b₁ = 10 and b₂ = 6 , then
A = [tex]\frac{1}{2}[/tex] × 5 × (10 + 6) = 0.5 × 5 × 16 = 40 cm²

y=-2(x + 1)2+3
write in standard form
y = -2(x + 1)² + 3
y = -2(x² + 2x + 1) + 3
y = -2x² - 4x - 2 + 3
y = -2x² - 4x + 1
Answer:
4x + y = -1
just simplify then re-write

please help i’ve done a (5x) but i need b) and c)
Answer:
b would be 6xy
c would be 6xy as well
Step-by-step explanation:
Not really sure how to explain it, I just know it
Answer:
b) 6xy
c) 6xy
Step-by-step explanation:
b) 6 × x × y
Since there are no like terms, just straight away remove the multiplication signs. So the answer is:
= 6xy
c) 2 × x × 3 × y
2 and 3 are like terms since they are both natural numbers (positive integers), you can multiply 2 with 3. The answer will be:
= 6xy
Suppose you have 30 CDs. You know that you have 11 more CDs that your friend. Write an equation to find the number of CDs your friend has.

PLEASE HELP WILL GIVE BRAINLIEST!!
Answer:
305.5 sq inches
Step-by-step explanation:
A (trapezoid) = 1/2·h·(sum of bases)
A = 1/2(17)(8 + 23)
A = 8.5(31)
A = 263.5
A(triangle) = 1/2·b·h
A = 1/2·(6)·(17-3)
A = 3(14)
A = 42
Total Area = 263.5 + 42.0 = 305.5 sq in

Solve each equation for y. Use the given values for x to find the values for y. Write answers as ordered pairs.
Answer:
1. x =-4 (-4,27)
x =0 (0,3)
x = 2 (2 , -9)
2. x = -1 (-1 , 3)
x = -2 (-2 , 2)
x = -3 ( -3, 1)
3. x = -3 (-3 , 13)
x = 1 (1 , 1)
x = -2 ( -2, 10)
4. x =2 (2 , 24)
x = 3 (3 , 30)
x = -2 (-2 , 0)
5.x = -3 (-3 , -2)
x = 2 (2 ,-12 )
x =4 (4 , -16)
6. x = -1 (-1 , -2)
x = 0 (0 , 2)
x = 2 (2 , 10)
7. x = -2 (-2 , -10)
x = 0 (0 , -14)
x = 3 (3 , -20)

Answer:
B) 114.511m^3
Step-by-step explanation:
Formula of a cylinder is πr^2 x h
r = radius (half of diameter)
h = height
Since it is 3/4 full you only do 3/4 of the height so- 0.75 x 9.60 which equals 7.2
Half of the diameter is 2.25. 2.25^2 = 5.0625.
The volume of the cylinder = 5.0625π x 7.2
By solving this, you will get approximately 114.511 m^3 as your answer.
