Answer:3x^2-5x+2=0
Step-by-step explanation:
Format of a quadratic equation= ax^2 +bx+c
Let x=1 and 2/3
When x=1
x-1=0.......(1)
When x=2/3
x-2/3=0.........(2)
Compare the equations
(x-1)(x-2/3)=0
x^2-2/3x-x+2/3=0
x^2-5/3x+2/3=0
Multiply all terms by 3
3x^2-5x+2=0
Can someone help me please
Answer:
The answer to number one is 11√17
The answer to number two is 4
Step-by-step explanation:
In number one: once you get both radicands to be equal, then you can add them. Like of it like 3x+2x. The x’s are like terms, so you can add them together.
In number two: the √5 on the top and bottom cancel out. This leaves 12/3 which is equal to 4.

Match the Exponential functions to the Y intercept.
Answer:
f(x)= -10^x-1-10= (0,-101/100)
f(x)= -3^x-2-1= (0,-10/9)
f(x)= -3^x+5-9= (-252)
f(x)= -17^x-1+2 = (0,33/17)
The maximum height of a vehicle that can pass under a bridge is 12 feet 5 inches. A truck measures 162 inches in height. Which best explains whether or not the truck can pass safely under the bridge?
Answer:
The truck can not safely pass under the bridge
Step-by-step explanation:
The maximum height in inches is 149in.
12 feet times 12 inches = 144 in
144 +5 = 149in
If the truck is 162 inches than it would not be safe for it to pass under the bridge.

the side of a square is 32/5, what is the area of the square
Answer: 1,024/25 or 40.96
Step-by-step explanation:
The length of one side of a square is 32/5, and all sides of a square have the same length, then all sides of the square have 32/5 as the length.
In order to get the area of the square, you need to multiply one side by another.
32/5 * 32/5 = 1,024/5 (fraction form)
32/5 = 6.4
6.4 * 6.4 = 40.96 (decimal form)

HOW DO I FIND THE AREA OF DEF?
Answer:
169.7
Step-by-step explanation:
first lets find the other side of the small triangle
cos(30 degrees)=(7*sqrt (3))/x
x*cos(30 degrees)=7*sqrt (3)
x=(7*sqrt (3))/cos(30 degrees)
x=14
14/14=1
so proportion is 1/1
thus the bottom the outer part of the triangle is also 7*sqrt(3)
now, for the area
lets find the 2 side length of the triangle we need
DE: 14+14=28
DF: 7*sqrt(3)+7*sqrt(3)=14*sqrt(3)
let's find EF,
sin(30 degrees)=x/28
x/28=sin( 30 degrees)
x=28*sin( 30 degrees)
x=14
A=(14*sqrt(3))*14*0.5
A=(14*sqrt(3))*7
A= around 169.7
Answer:
≈169.7
Step-by-step explanation:
cos30 = (7[tex]\sqrt{3}[/tex])/x
x= (7[tex]\sqrt{3}[/tex])/cos30 = 14
h = 14+14 = 28
sin30 = EF/28
EF = sin30 * 28 = 14
tan30 = 14/DF
DF = 14/tan30 ≈ 24.248
Area = 24.248*14/2 ≈ 169.74 ≈ 169.7

Solve 3^x - 5. What are the exact and approximate solutions?
Answer:
x = log(5) / log(3)
x=1.46497
Step-by-step explanation:
3^x - 5 =0
Add 5 to each side
3^x = 5
Take the log of each side
log 3^x = log 5
We know log a^b = b log (a)
x log (3) = log (5)
Divide side by log (3)
x = log(5) / log(3)
x=1.46497

Step-by-step explanation:
500/500=1
x / x = 1
Answer:
The answer is 1.Step-by-step explanation:
This is because when you divide a number with each other then they cancel out to equal 1. This can happen with the letter x. So, x/x = 1.
Going back to the question 500/500 can cancel out to become 1.

UN RECOLECTOR COMPLETA CUATRO CAJAS DE CAFE CADA CAJA LE CAVE 25/2 DE KILOGRAMOS DE CAFE SI SE RECOJE DIARIAMENTE CUATRO CAJAS¿CUANTOS KILOGRAMOS DE CAFE RECOJE EN TOTAL?
Answer:
El recolector recoge un total diario de 50 kilogramos.
Step-by-step explanation:
(The following problem is written in Spanish and for such reason explanation will be held in the same language)
La masa total diaria recogida es igual al número de cajas recogidas por día y la capacidad de la caja. Entonces:
[tex]m = n \cdot m_{unit}[/tex]
[tex]m = (4\,cajas)\cdot \left(\frac{25}{2}\,\frac{kg}{caja} \right)[/tex]
[tex]m = 50\,kg[/tex]
El recolector recoge un total diario de 50 kilogramos.
The lengths of a lawn mower part are approximately normally distributed with a given mean Mu = 4 in. and standard deviation Sigma = 0.2 in. What percentage of the parts will have lengths between 3.8 in. and 4.2 in.? 34% 68% 95% 99.7%
Answer:
b) 68%
The percentage of the parts will have lengths between 3.8 in. and 4.2 in
P( 3.8 ≤ x ≤ 4.2) = 0.6826 = 68 %
Step-by-step explanation:
Let 'X' be the normally distributed
mean 'μ'= 4 inches
standard deviation 'σ' = 0.2 inches
Case(i):-
when x₁ = 3.8 inches
[tex]Z_{1} = \frac{x_{1}-mean }{S.D} = \frac{3.8-4}{0.2} = -1[/tex]
Case(ii):-
when x₂= 3.8 inches
[tex]Z_{2} = \frac{x_{2}-mean }{S.D} = \frac{4.2-4}{0.2} = 1[/tex]
The probability of the parts will have lengths between 3.8 in and 4.2 in
[tex]P( 3.8\leq x\leq 4.2) = P(-1\leq z\leq 1)[/tex]
= P(Z≤1) - P(Z≤-1)
= 0.5 +A(1) -(0.5-A(1)
= 2 A(1)
= 2×0.3413
= 0.6826
Conclusion:-
The percentage of the parts will have lengths between 3.8 in. and 4.2 in
P( 3.8 ≤ x ≤ 4.2) = 0.6826 = 68 %
