The polynomial p(x)=x^3-7x-6 has a non-factor of (x+1) rewrite p(x) as a product of linear factors.
Answer:
Using synthetic division suffices to answer your question:
Step-by-step explanation:
Synthetic division is the process by one reduces a large polynomial in your case [tex]x^3-7x-6[/tex] by a binomial in your case [tex](x+1)[/tex].
To do so one does the following:
[tex]\begin{array}{cccccc}-1|& 1&0&-7&-6\\ & &-1&1&6 \\& 1&-1&-6&0 \end{array}[/tex]
Since we divided by a linear binomial it reduces the power by one which produces the following quadratic:
[tex](x^2-x-6)[/tex]
Which can be factored in the following, and I will provide the complete factorization as well:

Answer:
Length = 4 units
Step-by-step explanation:
Width = x units
Length = (x + 4) units
Area = 32 square units
length * width = 32
(x +4) *x = 32
x *x + 4 * x = 32
x² + 4x -32 = 0
Sum = 4
Product = -32
Factor = 8 , (-4)
x² + 4x -32 = 0
x² + 8x - 4x - 4 * 8 = 0
x(x + 8) - 4(x +8) = 0
(x + 8) (x - 4) = 0
(x + 8) is ignored because measurements will not have negative sign.
x-4 =0
x = 4
Width = 4 units
Length = x + 4 = 4 + 4 = 8 units
Can someone please explain this?
Answer:
-pi
Step-by-step explanation:
as x equals zero, g(x) = -3.14 = -pi
Your answer would be the second option, -π.
This is because as x approaches 0, cos(x + π) approaches cos(π) = -1. On top, x + π as x approaches 0 will tend to π, so you end up with π/-1. This simplifies to -π.

Rylee shopped at a clothing store, where she spent $36.50 plus 8% tax. Then, she spent $25 to refuel her car at the gas station. Finally, she bought groceries worth $23.50. At the grocery checkout, she handed over a coupon for a 20% discount on her purchase. what is her net change
Rylee's total spending was $39.42 for clothing (including tax), $25 for gas, and $18.80 for groceries (after applying a 20% discount). Summing these up, her total expenditure for all purchases was $83.22.
Explanation:This is a question involving basic arithmetic and percentage operations. In total, Rylee made three different purchases. She shopped for clothing costing $36.50 and paid 8% tax on it, which amounts to $36.50 * 0.08 = $2.92. Therefore, her total expenditure at the clothing store was $36.50 + $2.92 = $39.42. She then spent $25 to refuel her car.
Lastly, she bought groceries worth $23.50, but had a 20% discount coupon so she only paid 80% of the price, which is $23.50 * 0.80 = $18.80. If we add these expenditures together, we can find that Rylee's total spending was $39.42 (clothing) + $25 (gas) + $18.80 (groceries) = $83.22.

Leigh bought a conical candle wax mold. The height of the mold is 18.9 inches and the radius of the inside of the top of the conical
mold is 2.1 inches. She fills the mold completely with candle wax so that it is level with the top of the conical mold.
Answer:
87.28 cubic inches
Step-by-step explanation:
Leigh wants to fill the conical candle wax mold completely with candle wax.
We have to calculate the volume of the cone by the formula :
[tex]V=\pi r^2\frac{h}{3}[/tex]
Here, V = volume
r = radius = 2.1 inches
h = height = 18.9 inches
By substituting these values given, into the formula
[tex]V=\pi (2.1)^2(\frac{18.9}{3})[/tex]
= (27.783)π
= 87.28 inch³
Conical mold can hold 87.28 inch³ candle wax.
use the given information to find the p-value. also use a0.05 significance level and state the conclusion about the null hypothesis (reject the null hypothesis or fail tor rejected the null hypothesis)
With H1 : p < 3/5; the test statistic is z = -1.68
A: 0.093 ; fail to reject the null hypothesis
B: 0.0465 ; fail to reject the null hypothesis
C: 0.0465 ; reject the null hypothesis
D: 0.09535 ; fail to reject the null hypothesis
With H1 : p > 0.383, the test statistic is z = 0.41
A: 0.6591 ; fail to reject the null hypothesis
B: 0.3409 ; fail to reject the null hypothesis
C: 0.3490 ; reject the null hypothesis
D: 0.6818 ; reject the null hypothesis
Answer:
(a) C: 0.0465 ; reject the null hypothesis
(b) B: 0.3409 ; fail to reject the null hypothesis
Step-by-step explanation:
Firstly, the decision rule based on P-value to reject the null hypothesis or fail to reject the null hypothesis is given by;
If the P-value of test statistics is less than the level of significance, then we have sufficient evidence to reject our null hypothesis.If the P-value of test statistics is more than the level of significance, then we have insufficient evidence to reject our null hypothesis due to which we fail to reject our null hypothesis.(a) Now, we are given alternate hypothesis, [tex]H_1[/tex] : p < 3/5
Also, z test statistics is -1.68. Since this is a left tailed test, so P-value is given by;
P-value = P(Z < -1.68) = 1 - P(Z [tex]\leq[/tex] 1.68)
= 1 - 0.95352 = 0.0465
Since, the P-value of test statistics is less than the level of significance as 0.0465 < 0.05, so we have sufficient evidence to reject our null hypothesis due to which we reject the null hypothesis.
(b) Now, we are given alternate hypothesis, [tex]H_1[/tex] : p > 0.383
Also, z test statistics is 0.41. Since this is a right tailed test, so P-value is given by;
P-value = P(Z > 0.41) = 1 - P(Z [tex]\leq[/tex] 0.41)
= 1 - 0.6591 = 0.3409
Since, the P-value of test statistics is more than the level of significance as 0.3409 > 0.05, so we have insufficient evidence to reject our null hypothesis due to which we fail to reject the null hypothesis.
To determine the null hypothesis's fate, compare the p-value to α = 0.05. For the first scenario, H1: p < 3/5 with the test statistic z = -1.68, the conclusion is unclear without the exact p-value. For the second scenario, H1: p > 0.383 with z = 0.41, we fail to reject the null hypothesis as the p-value (0.3409) is higher than α.
Explanation:The task is to compare the p-value to the significance level (alpha, α) to determine if the null hypothesis should be rejected or not. If the p-value is less than or equal to α, reject the null hypothesis; otherwise, fail to reject it. The significance level given is α0.05.
First Scenario:
For H1: p < 3/5, the test statistic z = -1.68. Comparing the test statistic to the critical value for α=0.05 (which is between -1.65 and -1.64), -1.68 falls to the left of -1.65. However, without the exact p-value provided, the answer cannot be definitively chosen from the options. Still, the general rule is that if the test statistic is more extreme than the critical value, the null hypothesis is rejected.
Second Scenario:
For H1: p > 0.383, the test statistic z = 0.41. The p-value corresponding to z = 0.41 on the upper tail of a standard normal distribution is approximately 0.3409 (since the p-value is the area to the right of z). Therefore, the p-value is greater than α0.05, meaning that we fail to reject the null hypothesis.

Step-by-step explanation:
(a -b)² = a² - 2ab + b²
(2n - 5)² = 81
(2n)² - 2*2n*5 + 5² = 81
4n² - 20n + 25 = 81
4n² - 20n + 25 - 81 = 0
4n² - 20n - 56 = 0
4n² - 28n + 8n - 8*7 = 0
4n*(n -7) + 8*(n - 7) = 0
(n -7)(4n + 8) = 0

Answer:
Step-by-step explanation:

Constant : 7
Coefficient of 3d² = 3
Coefficient of d⁴ = 1
Final answer:
The expression 7 + 3d2 + d4 contains terms 7, 3d2, and d4, with coefficients 3 and 1 (implicit), and the constant 7. We identify each part according to algebraic principles and ensure to simplify and check our work.
Explanation:
The expression given is 7 + 3d2 + d4, which is a polynomial in d. The terms in this expression are 7, 3d2, and d4. Each part of a term can be classified as follows:
The coefficients are the numerical factors of the variables, which in this case are 3 for the term 3d2 and 1 for the term d4 (note: the coefficient is implicitly 1 here, since it's not written).
The constants are terms that do not contain variables, which here is only the number 7.
As a part of algebra, it's important to eliminate terms where possible to simplify the algebra and always check the answer to see if it is reasonable.
Scientists researching amphibians put tags on 30 frogs in a wetland area. Later, the scientists captured 520 frogs, of which 12 had tags. To the nearest whole number, what is the best estimate for the frog population?
Final answer:
The best estimate for the frog population, calculated using the mark-recapture method where 30 frogs were initially tagged and later 12 tagged frogs were found in a sample of 520, is approximately 208 frogs.
Explanation:
The question involves estimating the total population of frogs in a wetland area based on a mark-recapture study. The calculation is based on a proportion set up by the initial number of tagged frogs to the total initial tagging, compared with the number of tagged frogs found in a later sample to the size of that sample. This is a classic example of a capture-recapture method used in ecology for estimating population sizes.
The initial number of tagged frogs is 30, and later, from a sample of 520 frogs, 12 are found to be tagged. To estimate the total population (N), we set up the proportion as follows:
30 tagged frogs / N total population = 12 tagged frogs / 520 sample size
Now we cross-multiply and solve for N:
30N = 12 × 520
N = (12 × 520) / 30
N = 6240 / 30
N = 208
Therefore, the best estimate for the total frog population is approximately 208 frogs, rounded to the nearest whole number.

Ali was asked to factorise x^2y^2 + 36 - 4x^2 - 9y^2.He tried some ways of grouping terms as shown below.
x^2y^2 + 36 - 4x ^2 - 9y^2=(x^2y^2 + 36) - (4x ^2 + 9y^2)
x^2y^2 + 36 - 4x^2 - 9y^2=( x^2y^2 + 36 - 4x^2) -9y^2
x^2y^2 + 36 - 4x^2 - 9y^2=x^2y^2 + (36 - 4x^2 - 9y^2)
As he could not carry out factorisation with the above groupings,he concluded that the expression could not be factorised.Do you agree with him? Why or why not?
Answer:
It can be factorised
Step-by-step explanation:
Given
x²y² + 36 - 4x² - 9y² ( rearranging )
x²y² - 4x² - 9y² + 36 ( factor first/second and third/fourth terms )
= x²(y² - 4) - 9(y² - 4) ← factor out (y² - 4) from each term
= (y² - 4)(x² - 9)
Both factors are a difference of squares and factor in general as
a² - b² = (a - b)(a + b)
Thus
y² - 4
= y² - 2² = (y - 2)(y + 2) , and
x² - 9
= x² - 3² = (x - 3)(x + 3)
Hence
x²y² + 36 - 4x² - 9y² = (y - 2)(y + 2)(x - 3)(x + 3)
