Answer:
x = -1/5, x = i sqrt(30)/5, x = -i sqrt(30)/5
Step-by-step explanation:
25x^3 + 5x^2 + 30x + 6 = 0
5x^2(5x + 1) + 6(5x + 1) = 0
(5x + 1)(5x^2 + 6) = 0
5x + 1 = 0
5x = -1
x = -1/5
5x^2 + 6 = 0
5x^2 = -6
x^2 = -6/5
x = +/- sqrt(-6/5)
x = +/- i * sqrt(30)/5
x = i sqrt(30)/5 or x = -i sqrt(30)/5
Let f(x) = 5x +1.
Find f(2)
Answer:
f(2) =11
Step-by-step explanation:
Explanation:-
Given the function f(x) = 5x+1
Put x = 2
f(2) = 5(2)+1
⇒ f(2) = 10 +1
⇒ f(2) =11

Write an equation for the nth term of
the arithmetic sequence:
15,28,41 ....
Answer:
The equation for the nth term of the given arithmetic sequence is: [tex]\mathbf{a_n=13n+22}[/tex]
Step-by-step explanation:
We need to write an equation for the nth term of the arithmetic sequence:
15,28,41 ....
The equation for arithmetic sequence is: [tex]a_n=a_1+(n-1)d[/tex]
Where [tex]a_n[/tex] is the nth term, [tex]a_1[/tex] is first term and d is common difference
In the given sequence we have:
a₁ = 15
a₂ = 28
We can find common difference using the formula:
[tex]a_n=a_1+(n-1)d\\Put\: n=2, a_2=28\: and\: a_1=15\\a_2=a_1+(2-1)d\\28=15+d\\d=28-15\\d=13[/tex]
So, the common difference d is 13
Now, equation for nth term will be:
[tex]a_n=a_1+(n-1)d\\Put\:a_1=15, d=13\\a_n=15+(n-1)13\\Solving:\\a_n=15+13n-13\\a_n=13n+2[/tex]
So, the equation for the nth term of the given arithmetic sequence is: [tex]\mathbf{a_n=13n+22}[/tex]
where n=1,2,3..

A debit to the allowance for doubtful accounts is to reduce the allowance balance that was previously established and a credit to the accounts receivable is to remove the amount that will not be collected.
Write an algebraic expression for
the verbal expression:
"5 times the sum of a squared and
b minus 3 times the sum of
a and b".
Answer:
"5 times the sum of a squared and b minus 3 times the sum of
a and b".
5(a²+b) - 5(a+b)which can be simplified such as:
[tex]5\left(a^2+b\right)-5\left(a+b\right)=5a^2-5a[/tex]
Step-by-step explanation:
Given the verbal expression
"5 times the sum of a squared and b minus 3 times the sum of
a and b".
BREAKIN DOWN THE STATEMENT:
The sum of 'a' Squared and 'b' = a²+b
5 times the sum of a squared and b = 5(a²+b)The sum of a and b = a+b
3 times the sum of a and b = 5(a+b)Now, "5 times the sum of a squared and b minus 3 times the sum of
a and b".
5(a²+b) - 5(a+b)Let us simplify the algebraic expression
[tex]5\left(a^2+b\right)-5\left(a+b\right)[/tex]
[tex]=5a^2+5b-5a-5b[/tex]
simplify
[tex]=5a^2-5a[/tex]
Thus,
[tex]5\left(a^2+b\right)-5\left(a+b\right)=5a^2-5a[/tex]

In ΔFGH, f = 83 inches, g = 11 inches and ∠H=60°. Find the length of h, to the nearest inch.
Answer: 78
Step-by-step explanation:
The length of h to the nearest inch is 78 inches.
What is Law of Cosines?Law of cosines of triangle states that for three length of sides of the triangle, a, b and c opposite to the angles A, B and C respectively can be related as,
a² = b² + c² - 2bc cos(A)
Given that, In ΔFGH,
f = 83 inches, g = 11 inches and ∠H = 60°.
Using the law of cosines,
h² = f² + g² - 2fg cos(H)
Substituting,
h² = 83² + 11² - (2 × 83 × 11) cos (60°)
= 7010 - (1826 × 1/2)
= 7010 - 913
= 6097
h = √6097 = 78.083 inches ≈ 78 inches
Hence the length of h is 78 inches.

Of all the students in the school band, 6 play the trumpet. They represent 10% of the
total number of students in the band. How many students are in the band?
Which choice is NOT a correct way to check your answer?
A. The answer should be 10% of 6.
B. The answer multiplied by 10% should be 6.
C. 10% of the answer should be 6.
D. 6 should be 10% of the answer.
Answer:
Option A: The answer should be 10% of 6 is the correct answer.
Step-by-step explanation:
Given that:
6 students play trumpet. As they represent 10% of the total students.
Let,
x represent the number of students in the band.
10% of x = 6
By solving this, we will get the value for number of students in the band.
As x will be our answer,
The choices B, C and D are correct in the given scenario.
However,
10% of 6 cannot be the solution to the problem.

D
25%
Answer:
с ) 20%

Step-by-step explanation:

The attached table
Required
Determine the equation
First: We calculate the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Where:
[tex](x_1,y_1) = (-6,-1)[/tex]
[tex](x_2,y_2) = (0,9)[/tex]
The slope becomes:
[tex]m = \frac{9-(-1)}{0 - (-6)}[/tex]
[tex]m = \frac{9+1}{0+6}[/tex]
[tex]m = \frac{10}{6}[/tex]
[tex]m = \frac{5}{3}[/tex]
The equation is then calculated as:
[tex]y - y_2 = m(x-x_2)[/tex]
So, we have:
[tex]y - 9 = \frac{5}{3}(x - 0)[/tex]
[tex]y - 9 = \frac{5}{3}x[/tex]
Make y the subject
[tex]y = \frac{5}{3}x +9[/tex]

so we divide top and bottom by 1
6 dollars ÷ 1
1 dozen ÷ 1
=
6 dollars
1 dozen
=
6 dollars
dozen
= 6 dollars per dozen
