To solve this polynomial equation, we first factor the left side.
To factor x² + 8x + 12 = 0, look for factors of 12 that add to 8.
These factors are 6 and 2 so we have (x + 6)(x + 2) = 0.
So either x + 6 = 0 or x + 2 = 0 and solving for
x in each equation, our answer is {-6, -2}.

X^2-5x-14=0
Answer:
Step-by-step explanation:
Sum = -5
Product = -14
Factors = 2 , (-7) because 2*(-7) = -14 and 2 + (-7) = -5
x² - 5x - 14 = 0
x² + 2x - 7x - 14 = 0
x(x + 2) -7(x + 2) = 0
(x + 2)(x - 7) =0
x + 2 = 0 ; x -7 =0
x = -2 ; x = 7

5.87998 + 3.100 = [?]
The answer after performing mathematical operation is 8.97998 .
What is mathematical operations?
In order to add, subtract, multiply, or divide two or more quantities, one must perform a series of four fundamental operations known as mathematical operations. They involve the study of numbers and the order of operations, which are important in all other areas of mathematics like algebra, data processing, and geometry. Without employing mathematical operation rules, we are unable to solve the issue. The addition, subtraction, multiplication, and division operations all follow the same four fundamental rules.
Here the given ,
=> 5.87998 + 3.100
=> 5.87998
+ 3.10000
--------------------
8.97998
=> 5.87998+3.100=[8.97998]
Hence after performing mathematical operations the answer is 8.97998.

Approximate the solution to the equation f(x) = g(x) using three iterations of successive approximation. Use this graph as a starting point.
Answer:
[tex]x = \frac{ - 13}{16} [/tex]
Step-by-step explanation:
[tex]f(x) = {x}^{3} + 3 \\ g(x) = {x}^{2} + 2[/tex]
At the point of intersection, f(x)=g(x)
[tex] {x}^{3} + 3 = {x}^{2} + 2 \\ collect \: like \: terms \\ {x}^{3} - {x}^{2} + 3 - 2 = 0 \\ {x}^{3} - {x}^{2} + 1 = 0[/tex]
[tex] {x}^{3} - {x}^{2} + 1 = 0[/tex]
The above graph is that of the equation
[tex] {x}^{3} - {x}^{2} + 1 = 0[/tex]

CNNBC recently reported that the mean annual cost of auto insurance is 965 dollars. Assume the standard deviation is 113 dollars. You will use a simple random sample of 57 auto insurance policies.Find the probability that a single randomly selected policy has a mean value between 939.6 and 972.5 dollars.P(939.6 < X < 972.5)
Answer:
P(939.6 < X < 972.5) = 0.6469
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
CNNBC recently reported that the mean annual cost of auto insurance is 965 dollars. Assume the standard deviation is 113 dollars.
This means that [tex]\mu = 965, \sigma = 113[/tex]
Sample of 57:
This means that [tex]n = 57, s = \frac{113}{\sqrt{57}} = 14.97[/tex]
Find the probability that a single randomly selected policy has a mean value between 939.6 and 972.5 dollars.
This is the pvalue of Z when X = 972.5 subtracted by the pvalue of Z when X = 939.6. So
X = 972.5
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{972.5 - 965}{14.97}[/tex]
[tex]Z = 0.5[/tex]
[tex]Z = 0.5[/tex] has a pvalue of 0.6915
X = 939.6
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{939.6 - 965}{14.97}[/tex]
[tex]Z = -1.7[/tex]
[tex]Z = -1.7[/tex] has a pvalue of 0.0446
0.6915 - 0.0446 = 0.6469
So
P(939.6 < X < 972.5) = 0.6469

ABCD is a parallelogram
M is the midpoint of CB
N is the midpoint of AB
DA = a
DC = c
a) find, in terms of a and c, the vector of MN
b) show that CA is parralel to MN
Answer:
Part a)
MN = 0.5a-0.5c
Part b)
MN=0.5a-0.5c
CA=a-c
CA is parallel to MN because 2×MN = CA.
Step-by-step explanation:
Part a = We know that ABCD is a parallelogram (stated), thus opposite sides must be equal. So given that DA = a, CB = a, DC = c, AB = C.
MN = MB+BN, so as M is the midpoint of CB then MB = 1/2 a and as we are going against AB (we are doing BN) then it will be -0.5c as N is the midpoint of AB.
Part B= More of a mathswatch error, where you have to quite literally put the precise answer. CA = CD+DA so -c (as we are going the opposite way to DC) + a.
CA = -c+a
Now CA is a multiple of MN. But Mathswatch prefers if you say that CA is parallel to MN because MN times 2 is equal to CA
In this exercise we have to use the knowledge of parallelogram and vectors to give the values of each one of them, like this:
A) MN = 0.5a-0.5c
B)CA is parallel to MN because 2×MN = CA.
First, we have to remember the definition of parallelogram:
A polygon is any flat closed shape made of straight line segments. A parallelogram is a polygon with 4 sides in which sides that don't touch each other are parallel.A) We know that ABCD is a parallelogram, thus opposite sides must be equal. So given that:
[tex]DA = a,\\CB = a, \\DC = c, \\AB = C.[/tex]
[tex]MN = MB+BN\\MB = 1/2\\BN=-0.5c\\MN = 0.5a-0.5c[/tex]
B)Where you have to quite literally put the precise answer, so we have that:
[tex]CA = CD+DA \\CD=-c\\DA=a\\CA = -c+a\\[/tex]

I am assuming you want me to answer the equation provided in the picture, therefore I will provide you with the answer.
So we have [tex]\frac{3}{5} x[/tex] = 21
When it comes to equations with a variable, our goal is to isolate the variable, so let's start.
[tex]\frac{3}{5} x[/tex] = 21
1. Combine multiplied terms into a single fraction :
[tex]\frac{3x}{5}[/tex] = 21
2. Multiply both sides by the denominator :
5 * 3/5 = 3
5 * 21 = 105
3x = 105
3. Divide both sides by 3 :
[tex]\frac{3x}{3} = \frac{105}{3 }[/tex]
x = 35
