Solve 25x^2-30=0
Round the answer to the nearest hundredth
x=-1.10 and x=1.10
x=-26.15 and x=1.15
x=0
x=-0.83 and x=0.83
Answer:
x = - 1.10 and x = 1.10
Step-by-step explanation:
Given
25x² - 30 = 0 ( add 30 to both sides )
25x² = 30 ( divide both sides by 25 )
x² = [tex]\frac{30}{25}[/tex] ( take the square root of both sides )
x = ± [tex]\sqrt{\frac{30}{25} }[/tex]
x = - 1.10 and x = 1.10 ( to the nearest hundredth )
The correct answer is a. x = -1.10 and x = 1.10 .
To solve the quadratic equation [tex]\( 25x^2 - 30 = 0 \)[/tex], we first add 30 to both sides of the equation to isolate the quadratic term:
[tex]\[ 25x^2 = 30 \][/tex]
Next, we divide both sides by 25 to solve for [tex]\( x^2 \)[/tex]:
[tex]\[ x^2 = \frac{30}{25} \] \[ x^2 = 1.2 \][/tex]
Now, we take the square root of both sides to solve for x. Remember that when taking the square root of a number, we must consider both the positive and negative square roots:
[tex]\[ x = \pm\sqrt{1.2} \][/tex]
Using a calculator, we find the square root of 1.2 and round to the nearest hundredth:
[tex]\[ x = \pm1.095445115... \][/tex]
Rounded to the nearest hundredth, the solutions are:
[tex]\[ x = -1.10 \] \[ x = 1.10 \][/tex]
Therefore, the correct options are x = -1.10 and x = 1.10 . The other options provided [tex](\( x = -26.15 \)[/tex] and x = 1.15 , x = 0 , x = -0.83 and x = 0.83 are incorrect and do not satisfy the original equation.
The complete question is- Solve [tex]25x^2-30=0[/tex]

Classify the expression: 5x + 2x - 3
A. Quadratic expression
B. Linear expression
C. Cubic expression
D. Exponential expression
The expression [tex]\(5x + 2x - 3\)[/tex] is a linear expression.
The expression [tex]\(5x + 2x - 3\)[/tex] represents a linear expression because it consists of terms involving only the variable \(x\) raised to the power of 1. In other words, each term is a linear term.
Linear expressions depict relationships that are straight lines when graphed on a Cartesian plane. In this case, \(5x\) and \(2x\) are both linear terms since they involve the variable \(x\) raised to the first power, while the constant term \(-3\) does not involve \(x\) at all.
The expression simplifies to [tex]\(7x - 3\),[/tex] maintaining its linear form. Linear expressions are fundamental in algebra and represent relationships with constant rates of change.

5.241 divided by 3 please help me
The required, 5.241 divided by 3 equals approximately 1.747.
To divide 5.241 by 3, we can perform the division as follows:
1.747
------------
3 | 5.241
To start, we divide the whole number part, 5, by 3. The result is 1, which becomes the whole number part of the quotient.
Next, we bring down the decimal point and consider the decimal part of the dividend, which is 0.241. We can continue the division process by adding a decimal point to the quotient and placing a 0 to the right of the decimal point.
1.747
3 | 5.241
- 3
-----
24
Now, we divide 24 by 3, which gives us 8. We bring down the next decimal digit, which is 1, and continue the division:
1.747
3 | 5.241
- 3
-----
24
- 24
-----
1
Since there are no more decimal digits to bring down, we have finished the division. The final quotient is 1.747, rounded to three decimal places.
Therefore, 5.241 divided by 3 equals approximately 1.747.

how do you graph a quadratic with (a) in front of the x
Answer:
Remember PEMDAS? That comes into play here. Just multiply your x value with 1/3 and then square. After that just add the 4.
Step-by-step explanation:
Write the equation of a function whose parent function, f(x) = x + 5, is shifted 3 units to the right.
a) g(x) = x + 3
b) g(x) = x + 8
c) g(x) = x − 8
d_ g(x) = x + 2
Answer:
[tex]g(x) = x + 2[/tex]
Step-by-step explanation:
Parent function [tex]f(x) = x + 5[/tex], is shifted 3 units to the right.
If f(x) is shifted 'a' units to the right then f(x) becomes f(x-a)
If f(x) is shifted 'a' units to the left then f(x) becomes f(x+a)
[tex]f(x) = x + 5[/tex], is shifted 3 units to the right.
Then we subtract 3 from x
So , [tex]f(x) = x + 5[/tex] becomes [tex]f(x-3) = x-3 + 5=x+2[/tex]
[tex]g(x) = x + 2[/tex]
The equation of function will be;
g (x) = x + 2
Option d is true.
What is Function?
A relation between a set of inputs having one output each is called a function.
Given that;
Parent function, f(x) = x + 5 is shifted 3 units to the right.
Since, If a function f(x) is shifted 'a' units to the right then function f(x) becomes f(x-a).
So, The equation of function will be calculated as;
The parent function is shifted 3 units to the right.
Then, we subtract 3 as;
g (x) = x + 5 - 3
g (x) = x + 2
Thus, The equation of function will be;

What is the 30th term of the linear sequence below?
-4, -1,2,5,8,...
Answer:
The 30th term is 83
Step-by-step explanation:
we know that
An arithmetic sequence is a sequence of numbers such that the difference of any two successive members of the sequence is a constant called the common difference d
in this problem
[tex]a_1=-4\\a_2=-1\\a_3=2\\a_4=5\\a_5=8[/tex]
so
[tex]a_2-a_1=-1-(-4)=3\\a_3-a_2=-2-(-1)=3\\a_4-a_3=-5-2=3\\a_5-a_4=-8-5=3[/tex]
The common difference d is 3
We can write an Arithmetic Sequence as a rule:
[tex]a_n=a_1+d(n-1)[/tex]
Find out the 30th term
we have
[tex]n=30\\d=3\\a_1=-4[/tex]
substitute
[tex]a_n=-4+(3)(30-1)[/tex]
[tex]a_n=-4+(3)(29)[/tex]
[tex]a_n=83[/tex]
Final answer:
The 30th term of the linear sequence is 83, found using the formula for the nth term of a linear sequence an = a1 + (n - 1)d, with a common difference of 3.
Explanation:
To find the 30th term of the linear sequence given by -4, -1, 2, 5, 8,..., first identify the common difference between consecutive terms. In this sequence, each term increases by 3. So, the common difference (d) is 3.
To find the nth term of a linear sequence, use the formula:
an = a1 + (n - 1)d, where
an is the nth term,
a1 is the first term, and
d is the common difference.
For our sequence:
a1 = -4 (the first term),
d = 3,
n = 30 (since we are finding the 30th term).
Plugging into the formula gives:
a30 = -4 + (30 - 1) × 3
a30 = -4 + 29 × 3
a30 = -4 + 87
a30 = 83
Therefore, the 30th term of the sequence is 83.

A manufacturing company produced 1,800 vehicle.of those 30% were trucks 25% were sports cars, and 10% were vans. How many of the vehicle were not trucks,sports cars, or vans ?
Answer:
630
Step-by-step explanation:
if you add the percentages of the trucks, sport cars and vans you get:
30% + 25% + 10% = 65%. So to find the percentage of vehicles that aren't in this categories you substract this percentage from 100%.
100% - 65% = 35%
This means that 35% of the vehicles aren't in those categories, so to find the amount you just multiply the total of vehicles with the percentage an then divide by 100
(1,800*35)/100 = 630 vehicles
A batch consists of 12 defective coils and 88 good ones. Find the probability of getting two good coils when two coils are randomly selected if the first selection is replaced before the second is made. 0.7744 0.7733 0.0144 0.176
Answer:
The probability of getting two good coils when two coils are randomly selected if the first selection is replaced before the second is made is 0.7744
Solution:
Total number of coils = number of good coils + defective coils = 88 + 12 = 100
p(getting two good coils for two selection) = p( getting 2 good coils for first selection ) [tex]\times[/tex] p(getting 2 good coils for second selection)
p(first selection) = p(second selection) = [tex]\frac{\text { number of good coils }}{\text { total number of coils }}[/tex]
Hence, p(getting 2 good coil for two selection) = [tex]\frac{88}{100} \times \frac{88}{100} =\bold{0.7744}[/tex]
Probability of selecting two good coils with replacement: [tex]\(0.88 \times 0.88 = 0.7744\)[/tex]. Correct answer is D) 0.7744.
To solve this problem, we need to calculate the probability of selecting two good coils when the first selection is replaced before the second is made. This means the selections are independent.
Here are the steps:
1. Calculate the total number of coils:
12 defective +88 good $=100$ total
2. Determine the probability of selecting a good coil on the first draw:
[tex]\[ P(\text{good on first draw}) = \frac{88}{100} = 0.88 \][/tex]
3. Since the first coil is replaced, the probability of selecting a good coil on the second draw is the same:
[tex]\[ P(\text{good on second draw}) = \frac{88}{100} = 0.88 \][/tex]
4. Calculate the probability of both events (selecting two good coils):
[tex]\[ P(\text{two good coils}) = P(\text{good on first draw}) \times P(\text{good on second draw}) \][/tex]
[tex]\[ P(\text{two good coils}) = 0.88 \times 0.88 = 0.7744 \][/tex]
Therefore, the probability of getting two good coils when two coils are randomly selected with replacement is:
[tex]\[\boxed{0.7744}\][/tex]
So the correct answer is:
D) 0.7744
The correct question is:
A batch consists of 12 defective coils and 88 good ones. Find the probability of getting two good coils when two coils are randomly selected if the first selection is replaced before the second is made.

Consider the cubic function f(x) = x^3 + ax^2 + bx + 4 where (a) and (b) are constants. When f(x) is divided by x-3, the remainder is 10. When f (x) is divided by x+1, the remainder is 6.
Show that a = -1 and b = -4
Answer:
see explanation
Step-by-step explanation:
Using the Remainder theorem
If f(x) is divided by (x - h) then f(h) = remainder, thus
f(3) = 3³ + a(3)² + b(3) + 4 = 10, that is
27 + 9a + 3b + 4 = 10
9a + 3b + 31 = 10 ( subtract 31 from both sides )
9a + 3b = - 21 → (1)
f(- 1) = (- 1)³ + a(- 1)² + b(- 1) + 4 = 6, that is
- 1 + a - b + 4 = 6
a - b + 3 = 6 ( subtract 3 from both sides )
a - b = 3 → (2)
Rearrange (2) expressing a in terms of b
a = 3 + b → (3)
Substitute a = 3 + b into (1)
9(3 + b) + 3b = - 21 ← distribute and simplify left side
27 + 9b + 3b = - 21
12b + 27 = - 21 ( subtract 27 from both sides )
12b = - 48 ( divide both sides by 12 )
b = - 4
Substitute b = - 4 into (3)
a = 3 - 4 = - 1
Hence a = - 1 and b = - 4

Step-by-step explanation:
A game's packing cost is $18
A ticket for the game is $33
Your family gave you $200 + minivan
Let's say the number of friends (including yourself) you go with to the game is f.
Equating this expression;
$18 + $33f ≤ $200
$33f ≤ $200 - $18
$33f ≤ $182
f ≤ [tex]\frac{182}{33}[/tex]
f ≤ 5.515151515
Since we cannot have 0.515151515 friends, the number of friends (including yourself attending the game must be 5).

What is the first step in which the student made an error
Final answer:
To identify where an error might have occurred, students should be aware of common mistakes, review personal feedback, and reflect on their thought processes. This helps in understanding and correcting errors, leading to improvement in critical and reflective thinking.
Explanation:
The first step in identifying an error in a student's work is to be cognizant of common mistakes that students make. By reviewing a common errors list and reflecting upon feedback from instructors, a student can pinpoint problem areas in his or her academic practice. Starting with the prediction and diagnosis of one's own learning process is essential. This may include recognizing patterns in mistakes, understanding why an error was made, or consulting with a teacher for further clarification. Once the source of the error is identified, the student can work on corrective measures to avoid similar issues in the future. Frequently, errors in thinking or application are not due to a lack of intelligence, but rather to the way our minds are wired, leading to characteristic mistakes that can be anticipated and mitigated with practice and reflection.
