If f(x) = x3 + 12x2 +41x + 30 and f(-6) = 0, then find all of the zeros of
f(x) algebraically.
Answers
Answer:
-6, -5, -1
Step-by-step explanation:
Based on the question, (x+6) is a factor of f(x).
With this, you can do the long division method of dividing f(x) with (x+6) {Refer to the image}.
You'll get x²+6x+5 as a result.
Factorise it and you'll get
x²+6x+5 = (x+1)(x+5)
Then let (x+1)(x+5) = 0, x = -1, -5
Zero's of f(x) are -6, -5 -1
[tex]\text{Given that,}\\\\f(x) = x^3 +12x^2 +41x +30~~ \text{and} ~~ f(-6)=0\\\\\text{Since f(x)=0 when x = -6,}~ ~x-6 ~\text{is a factor of f(x).}\\\\x^3+12x^2+41x+30 = 0\\\\\implies x^3+6x^2+6x^2+36x+5x+30=0\\\\\implies x^2(x+6) +6x (x+6) +5(x+6)=0\\\\\implies (x+6)(x^2+6x+5)=0\\\\\implies (x+6)(x^2+5x+x+5)=0\\\\\implies (x+6)\textbf{[}x(x+5)+(x+5)\textbf{]}=0\\\\\implies (x+6)(x+1)(x+5)=0\\\\\text{Hence the roots are,}~ x = -6,~ x=-1~ \text{and}~ x = -5[/tex]

Using an arithmetic sequence, it is found that the clock chimes 132 times in a 24-h period.
What is an arithmetic sequence?In an arithmetic sequence, the difference between consecutive terms is always the same, called common difference d.
The nth term of an arithmetic sequence is given by:
[tex]a_n = a_1 + (n - 1)d[/tex]
In which [tex]a_1[/tex] is the first term.
The sum of the first n terms is given by:
[tex]S_n = \frac{n(a_1 + a_n)}{2}[/tex]
In this problem, as the day is divided in two 12-hours period, the total will be twice the sum of the 12 elements of the following sequence:
{0, 1, 2, 3, ..., 11}
In which [tex]a_1 = 0, a_11 = 11, n = 12[/tex].
Then:
[tex]T = 2\frac{12(0 + 11)}{2} = 12 \times 11 = 132[/tex]

Can y’all help with this? (It’s exponential and decaying factors). Thanks!!
Answers
Answer:
2.37×10^-11 milliliters
Step-by-step explanation:
The exponential model for decay is ...
y = a·b^x
where 'a' is the initial value, 'b' is the decay factor, and x is the number of intervals over which the decay is taking place.
__
Here, you're given an initial value of a=500 mL.
The decay factor is 1 more than the decay rate, so is ...
b = 1 -12% = 0.88
We are asked for the remaining amount after 240 intervals (breaths), so that will be ...
y = 500·0.88^x
y = 500·0.88^240 ≈ 2.37×10^-11 . . . . milliliters

Guiding Statement
You must find x before you can find y. If an altitude is dropped from the right angle to the hypotenuse, then the value of the altitude = the two parts of hypotenuse multiplied together = the altitude squared.
Formula
Perhaps, instead of all that language, it is easier just to show you this in terms of what you have been given.
Solution
x^2 = 72 Factor 72 into prime factors.
x^2 = 8 * 9
x^2 = 2 * 2 * 2 * 3 * 3 Take the square root of both sides.
√x^2 = √(2 * 2 * 2 * 3 * 3)
Rule
For every pair of equal prime factors, take 1 factor outside the root sign and throw the other one away.
√x^2 = √(2 * 2 * 2 * 3 * 3)
x = √(2 * 2 * 2 * 3 * 3) Apply the rule
x = 2 * 3 √2
x = 6√2
Now with y
a = 6√2
b = 12
c = y Use the Pythagorean Theorum
c^2 = a^2 + b^2
c^2 = (6√2)^2 + 12^2
c^2 = 36*2 + 144
c^2 = 72 + 144
c^2 = 216
c = 6 √6
answer
x = 6√2
y = 6√6

here , we've been given a right angled triangle along with the measure of two of its sides.
and , we've to find the measure of its third side.
so , we'll be using Pythagoras Theorem to find the measure of the third side.
but first , let's take a look at what Pythagoras Theorem is-
Pythagoras theorem states that the square of the hypotenuse of the triangle is equal to the sum of squares of the remaining two sides.
according to the figure ,
side AB = hypotenuse = 60 cm
side AC = perpendicular = 48 cm
side BC = base = a
now by using Pythagoras Theorem ,
[tex]H {}^{2} = P {}^{2} + B {}^{2} \\ \\ (60) {}^{2} = (48) {}^{2} + a {}^{2} \\ \\ 3600 = 2304 + a {}^{2} \\ \\ a {}^{2} = 1296 \\ \\ a = \sqrt{1296} \\ \\ a = 36[/tex]
therefore ,
option ( 4 ) 36 is correct.

Answer:
36. (Option 4)[tex] \\ [/tex]
Step-by-step explanation:
Here, A right angled triangle is given with the measure of two sides and we are to find the measure of the third side.
We'll find the measure of third side with the help of the Pythagorean theorem,
[tex] \\ {\longrightarrow \pmb{\sf {\qquad (Base) {}^{2} + (Perpendicular {)}^{2} = (Hypotenuse {)}^{2} }}} \\ \\[/tex]
Here,
The base (BC) is aThe perpendicular (AC) is 48The hypotenuse (AB) is 60.[tex] \\ [/tex]
So, substituting the values in the formula we get :
[tex]\\ {\longrightarrow \pmb{\sf {\qquad (a) {}^{2} + (48 {)}^{2} = ( 60{)}^{2} }}} \\ \\[/tex]
[tex] {\longrightarrow \pmb{\sf {\qquad (a) {}^{2} = ( 60{)}^{2} - (48 {)}^{2}}}} \\ \\[/tex]
[tex] {\longrightarrow \pmb{\sf {\qquad (a) {}^{2} =3600 - 2304}}} \\ \\[/tex]
[tex] {\longrightarrow \pmb{\sf {\qquad (a) {}^{2} =1296}}} \\ \\[/tex]
[tex] {\longrightarrow \pmb{\sf {\qquad a = \sqrt{1296}}}} \\ \\[/tex]
[tex] {\longrightarrow \pmb{\frak {\qquad a = 36 }}} \\ \\[/tex]

The measure of the third side (a) is 36.Val is going to plant b vegetable seeds in one garden and 3b + 10 vegetable seeds in another. How

⇒ -4x + 2 = -14⇒ -4x + 2 - 2 = -14 - 2⇒ -4x = -16Dividing -4 to both sides of the equation (according to step 2):

which is 5,291, written in scientific notation?
Answers
Answer:
5.291 x 10⁶
Step-by-step explanation:
Why is 5,291,000 written as 5.291 x 106 in scientific notation?
The purpose of scientific notation is for scientists to write very large, or very small, numbers with ease.
Calculating scientific notation for a positive integer is simple, as it always follows this notation:
a x 10b
Follow the steps below to see how 5,291,000 is written in scientific notation.
Step 1
To find a, take the number and move a decimal place to the right one position.
Original Number: 5,291,000
New Number: 5.291000
Step 2
Now, to find b, count how many places to the right of the decimal.
New Number: 5 . 2 9 1 0 0 0
Decimal Count: 1 2 3 4 5 6
There are 6 places to the right of the decimal place.
Step 3
Building upon what we know above, we can now reconstruct the number into scientific notation.
Remember, the notation is: a x 10b
a = 5.291 (Please notice any zeroes on the end have been removed)
b = 6
Now the whole thing:
5.291 x 10⁶
Step 4
Check your work:
10⁶ = 1,000,000 x 5.291 = 5,291,000

Answers
Answer:

Step-by-step explanation:
First, we need to plot the center point of the circle. (Shown in image). Once we plotted the center point, we need to count how many units is the radius away from the boundary.
Note: I have marked each unit by a "red point". Simply, count the number of "red points" to determine the radius.
⇒ Radius according to graph: 5 unitsWe can substitute the radius in the "area of circle" formula to determine the area. Keep in mind that pie is represented as 3.14.
⇒ Area of circle = πr²⇒ Area of circle = π(5)²Now, let's evaluate the area by simplifying the expression. Keep in mind that pie is represented as 3.14.
⇒ Area of circle = π × (5)²⇒ Area of circle = π × 5 × 5⇒ Area of circle = π × 25⇒ Area of circle ≈ 3.14 × 25 [π = 3.14]⇒ Area of circle ≈ 78.5 units²Please find x ft, pleeaase help

The null hypothesis in this situation is "There are no differences in the mean completion times among the temperatures compared".
What is a null hypothesis?This is a hypothesis that states the independent variable or factor being studied has not effect on the dependent variable.
This implies the temperature has no effect on the completion times of the paper-folding test.
What is the factor of interest?It is the effect of temperature because this is the factor being manipulated on purpose.
What is the dependent variable?This refers to the factor being studied, in this case, these are the spatial reasoning abilities, which are tested through a specific test.
