Use the quadratic formula to find the solutions to the equation.
3x2 - 10x + 5 = 0
Answers
Answer: A
Step-by-step explanation:
3x² - 10x + 5 = 0
a = 3 b = -10 c = 5
Δ = b²- 4ac = 100 - 4.3.5 = 40 > 0 => have 2 solutions
=> x = [tex]\frac{10+\sqrt{40} }{6}[/tex] or x = [tex]\frac{10-\sqrt{40} }{6}[/tex]
[tex]x= \frac{10\pm \sqrt{40} }{6}[/tex] is the solution to the given quadratic equation.
What is quadratic equation?
Quadratic equations are the polynomial equations of degree 2 in one variable of type f(x) = [tex]ax^{2} +bx+c[/tex] = 0 where a, b, c, ∈ R and a ≠ 0. It is the general form of a quadratic equation where 'a' is called the leading coefficient and 'c' is called the absolute term of f (x).
Quadratic formula = [tex]\frac{-b\pm \sqrt{b^{2} -4ac} }{2a}[/tex]
Given quadratic equation
[tex]3x^{2} -10x+5=0[/tex]
a = 3, b = -10, c = 5
Quadratic formula = [tex]\frac{-b\pm \sqrt{b^{2} -4ac} }{2a}[/tex]
[tex]x= \frac{-(-10)\pm \sqrt{(-10)^{2} -4(3)(5)} }{2\times3}[/tex]
⇒ [tex]x= \frac{10\pm \sqrt{100 -60} }{6}[/tex]
⇒ [tex]x= \frac{10\pm \sqrt{40} }{6}[/tex]
Hence, [tex]x= \frac{10\pm \sqrt{40} }{6}[/tex] is the solution to the given quadratic equation.

The table already give us a hint, which is a set of values that are telling us what is the value of every function f(x) and g(x) for a given value for 'x' variable.
From the table we know that f(x) decreases when x>0 and goes in the other direction when x<0.
g(x) goes on a different direction, when x>0, it gets bigger, and when x<0, the function decreases.
So the two functions do not have too much space for being equal.
So, you can use the points given in the table to start your test.
f(0)= 0,25 ^ 0=1 since a number raised to 0 is always 0.
g(0)=-0.75 * 0 + 1 = 1
f(1)=0.25^1=0.25 since a number raised to 1 is always equals to itself
g(1)=-0.75*1+1=0.25
So f(x)=g(x), when x=1 and when x=0

At first we need to graph the function [tex]y = 3\cdot x[/tex], whose representation is included in the figure attached below. The positive slope and the y-intercept equal to zero means that the inequality only takes any point below the line into account, that is, it covers Quadrants I and III partially and the Quadrant IV completely.

Ans:
ii) How many smaller pieces of wood will he have in total?
Ans:
Answers
Answer:
A. 30 inches
B. 11 pieces
Step-by-step explanation:
Piece 1 = 120 inches
Piece 2 = 210 inches
1. He wants the smallest pieces to be as long as possible without having any leftover, how long should each piece be?
Find the highest common factor of 120 and 210
120: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, and 120.
210: 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210.
The highest common factor of 120 and 210 = 30
Therefore, the smallest and longest pieces should be cut into 30 inches each
B. Total Smaller pieces of wood = piece 1 / 30 + piece 2 / 30
= 120/30 + 210/30
= 4 + 7
= 11 pieces

How many soap cakes can be placed in a box of size 56 cm x 0.4 m 0.26 m, if the size
of a soap cake is 7 cm x 5 cm x 2.5 cm?
Answers
Answer:
length of box = 56cm
breadth = 0.4m = 40cm
height = o.25m = 25cm
Volume of Box = Volume of soap × n
n = number of soaps.
LBH = lbh × n
56 × 40 × 25 = 7 × 5 × 2.5 × n
n = 56×40×25/35×2.5
n = 56000/87.5
n = 640
so, 640 soaps can be placed in the box.
