Answer:
A, B and D
Step-by-step explanation:
The zeros of f(x) are the points located on the x- axis, that is where y = 0
We can check which ones are the solutions by finding the zeros of f(x)
To find the zeros let f(x) = 0 , that is
(x² + 2x - 8)(x - 6) = 0 ← factorise the quadratic
(x + 4)(x - 2)(x - 6) = 0
Equate each factor to zero and solve for x
x + 4 = 0 ⇒ x = - 4
x - 2 = 0 ⇒ x = 2
x - 6 = 0 ⇒ x = 6
There are 3 zeros at x = - 4, x = 2, x = 6
These are located at A, B and D
Answer:
A, D, B
Step-by-step explanation:
The roots (zeroes) are the x values where the graph intersects the x-axis. To find the roots(zeroes), replace y with 0 and solve for x.

find the curved surface area of a cylindrical tank of base radius 30 cm and height 2m
Answers
Answer:
37 700m² (rounded off to 3 s.f.)
Step-by-step explanation:
When the curved surface area of a cylindrical tank is laid out, it will be like a rectangular piece of sheet with the circumference of the base circle as its length and the height as its breadth.
Circumference of base circle with radius 30cm = pi × 30 × 2
= 60pi
2m = 200cm
Curved surface are = 60pi × 200
= 12 000pi
= 37 700m² (rounded off to 3 s.f.)
[tex]{\pink{\underline{\textsf{\textbf{Answer : }}}}}[/tex]
➡️ 37,680m² will be the curved surface area of the cylindrical tank.
[tex]{\purple{\underline{\textsf{\textbf{Explanation : }}}}}[/tex]
Given that, A cylindrical tank of base radius is 30cm and it's height is 2m or, 200cm
We need to find the curved surface area
We know that,
➩ Curves surface area of a cylinder = 2πrh
r (radius) = 30cm.
h (height) = 200cm.
Therefore,
➩ Curves surface area of a cylinder:
➩ 2 × 3.14 × 30 × 200
➩ 2 × 18,840
➩ 37,680 m² ans.

Answers
Complete question :
Ann, Brian and Carol share the cost of a car. Ann pays 2/5 of the cost, Brian pays 1/3 and Carol pays the rest.
a) What fraction of the cost does Carol pay?
b) Ann pays $1600 more than Brian. Find the total cost of the car.
Answer:
4/ 15
8000
Step-by-step explanation:
A)
Fraction carol paid :
Total fraction = 1/1
Fraction paid by Ann and Brian = (2/5 +1/3)
(2/5 + 1/3) = (6 + 5) / 15 = 11/15
1 - 11/ 15 = 4/ 15
Ann = 2/5 ; Brian pays 1/3
Ann pay 1600 more than Brian
2/5 - 1/3 = (6 - 5) = 1/5
1/5 of amount = 1600
If :
1/5 = 1600
1 = x
1/5x = 1600
x = 1600 ÷1/5
Total amount = 8000

hcf and lcm of 120 and 180, shown your work
Answers
The HCM and LCM of 120 and 180 are 360.
What is HCF and LCM?The Highest Common Factor (HCF) of two or more given numbers is the largest number that divides each of the given numbers without leaving any remainder. The Least Common Multiple (LCM) of two or more numbers is the smallest of the common multiples of those numbers.
Given are two numbers as -
120 and 180
We can write 120 and 180 as -
120 = 2 x 2 x 2 x 3 x 5
180 = 2 x 2 x 3 x 3 x 5
HCF of 120 and 180 will be equal to = 2 x 2 x 3 x 5 = 60
Now, we can find LCM using the formula -
LCM(a, b) = (a x b)/HCF(a, b)
LCM(a, b) = (120 x 180)/60
LCM(a, b) = 2 x 180 = 360
Therefore, the HCM and LCM of 120 and 180 are 360.
