Answer:
x = 2/3 , -2
Hope this helps!
Answer:
x= 2/3
or
x= -2
Step-by-step explanation:
x(3x+4)=4
3x^2 +4x -4 = 0
(3x - 2)(x + 2)=0
3x - 2=0 or x + 2=0
x=2/3 or x=-2

If a fair 5-sided die is rolled 5 times, what is the probability that each possible outcome (1, 2, 3, 4, and 5) will occur exactly once
Answer:
0.0384
Step-by-step explanation:
Given a fair 5 sided die rolled 5 times.
Numbers on it are 1, 2, 3, 4, 5.
To find:
The probability that each number will occur exactly once.
Solution:
Formula for probability of an event E:
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]
At the first roll of die, any number can occur.
So number of possible outcomes = 5
Total number of possible outcomes = 5
[tex]P(1^{st}\ roll) = \dfrac{5}{5} = 1[/tex]
At the second roll of die, any number can occur other than that occurred in first roll.
So number of possible outcomes = 4
Total number of possible outcomes = 5
[tex]P(2^{nd}\ roll) = \dfrac{4}{5}[/tex]
At the third roll of die, any number can occur other than that occurred in first and second roll.
So number of possible outcomes = 3
Total number of possible outcomes = 5
[tex]P(3^{rd}\ roll) = \dfrac{3}{5}[/tex]
At the fourth roll of die, any number can occur other than that occurred in first, second and third roll.
So number of possible outcomes = 2
Total number of possible outcomes = 5
[tex]P(4^{th}\ roll) = \dfrac{2}{5}[/tex]
At the fifth roll of die, any number can occur other than that occurred in first, second, third and fourth roll.
So number of possible outcomes = 1
Total number of possible outcomes = 5
[tex]P(5^{th}\ roll) = \dfrac{1}{5}[/tex]
The required probability will be multiplication of all the five probabilities.
[tex]1 \times 0.8 \times 0.6 \times 0.4 \times 0.2 = \bold{0.0384}[/tex]

a long steel beam has a length of twenty-five meters on a cold day when the temperature is 0*c. what is the length of the beam on a hot day when t
Complete question is;
A long steel beam has a length of twenty-five meters on a coldday when the temperature is 0°C. What is the length of the beam on a hot day when T = 40°C. (α_steel = 1.1 × 10^(-5) °/C)
a. 25.00044 m
b. 25.0044 m
c. 25.011 m
d. 25.044m
e. 25.11 m
Answer:
Option C: 25.011 m
Step-by-step explanation:
We are given;
Initial Temperature; T1 = 0°C
Final Temperature; T2 = 40°C
Coefficient of linear expansion of steel; α_steel = 1.1 × 10^(-5) °/C
Initial length; L_o = 25 m
We know that formula for change in length is;
ΔL = LαΔT
Plugging in the relevant values, we have;
ΔL = 25 × 1.1 × 10^(-5) × (40 - 0)
ΔL = 0.011 m
Thus, new length is;
L1 = L_o + ΔL
L1 = 25 + 0.011
L1 = 25.011
rename fraction to similar fraction 6/8 and2/12=
Answer:
6/8=18/24
2/12 = 4/24
Step-by-step explanation:
If you want to make the fractions the same, look at the denominator.
6/8 and 2/12
what number can both 8 and 12 go into?
It goes into 24
so 6/8 would be 6*3 and 8*3 because whatever you do to the bottom, you do to the top and 8*3 is 24 so 6*3 is 18 and for 2/12 you multiply both by 2 since 12*2=24 and 2*2=4
I will do 6/8 only. You do the other fraction.
Pick a number, any number. How about 2?
Multiply the top and bottom number by 2.
6 x 2 = 12
8 x 2 = 16
We get 12/16.
Reducing 12/16 to the lowest terms we get 3/4.
Another fraction similar to 6/8 is 3/4. In fact, they are equivalent fractions.
Do the other fraction in like fashion.
Note: Each fraction given has more than one similar fraction.

The area of a circular wave expands across a still pond such that its radius increases by 8cm each second. Write a formula for the area A of the circle as a function of time t since the wave begins:
A=
Answer:
A(t) = π(8t)²
Step-by-step explanation:
Radius of a circular wave increases by 8 cm each second.
Every second radius of circular wave so the sequence of increase in radius will be,
8, 16, 24, 32.........(8t)
Here 't' = time
Since, area of a circle = πr²
Therefore, area of the circular wave after 't' seconds since the wave begins,
A(t) = π(8t)²

Express -2x+3y=6 in the form of ax+by+ca and indicate the values of a, b , c
Please answer
Answer:
-2x + 3y = 6
Rearrange
-2x + 3y - 6 = 0
ax + by + ca = 0
a = -2
b = 3
If ca was a typo, and you meant c, then c = -6.
However, if ca wasn't a typo, then:
ca = -6
-2c = -6
c = -6 / -2
c = 3
A product is marked down 15%; the sale price is $127.46. What
was the original price?
Answer: $ 149.95.
Step-by-step explanation:A product is marked down 15%; the sale price is $127.46. What was the original price? Substitute 127.46 for S.P and 15 for m in (1). So, the original price is $ 149.95.
The original price of the product will be $149.95.
What is the percentage?The quantity of anything is stated as though it were a fraction of a hundred.
A product is marked down 15%.
The sale price is $127.46.
Then the original price of the product will be
Let x be the original price.
(1 – 0.15)x = $127.46
0.85x = $127.46
x = $149.95

What is the difference between intersecting, perpendicular, and parallel?
Answer:
Parallel lines are lines in a plane that are always the same distance apart. Parallel lines never intersect. Perpendicular lines are lines that intersect at a right (90 degrees) angle.
Step-by-step explanation:
Answer:
Perpendicular lines are when two lines intersect each other at 90 degrees, parallel are when the two lines never touch, and also have the same slope, and then intersecting is when two or more lines cross each other in a plane.

Answer: 6
Step-by-step explanation: To evaluate this problem, the first thing
we want to do is plug in the appropriate values for a, b, and c.
When we do that, we get [tex]\frac{3(4)}{4(3) - (10)}[/tex].
A good rule of thumb for problems that involve division bars is to simplify what's above the division bar as much as you can and what's below the division bar as much as you can before you do your dividing.
So up top, we simplify 3(4) to get 12.
Down below, we want to multiply before we subtract.
So 4(3) is 12 and we have 12 - 10 which is 2.
So we have 12 / 2 which simplifies to 6.

Step-by-step explanation:
It appears to be just a slope problem in disguise. Where if you find the slope, you find the density of nickel. In this case, it would be copper. The slope appears to be closer to 9, and if you take some of the points and divide it, like where it seems to cross 4 and 35, you would get an answer close to 9. Same with 40 and 4.5, you get 8.89. The only answer closest to that would be H
