Someone help me on this question, please. I don't understand!!
The compound inequality for the area written in terms of x is 100 ≤ 20x ≤ 1,000, the solution is 5 ≤ x ≤ 50 and all the solutions are viable
How to select the compound inequality for the area written in terms of x?The given parameters are
Dimensions = 4x and 5
Area: 100 ≤ A ≤ 1,000
The area is calculated as
A = Product of dimensions
So, we have
A = 4x * 5
Evaluate
A =20x
Substitute A =20x in 100 ≤ A ≤ 1,000
100 ≤ 20x ≤ 1,000
So, the compound inequality for the area written in terms of x is 100 ≤ 20x ≤ 1,000
Divide through 100 ≤ 20x ≤ 1,000 by 20
5 ≤ x ≤ 50
Hence, the solution is 5 ≤ x ≤ 50 and all the solutions are viable

3. Consider the leading term of the polynomial function. What is the end behavior of the graph? (1 point)
2x7-8x6-3x5-3
O The leading term is 2x7. Since n is odd and a is positive, the end behavior is up and up.
O The leading term is 2x7.
Since n is odd and a is positive, the end behavior is down and down.
O The leading term is 2x7.
Since n is odd and a is positive, the end behavior is down and up.
O The leading term is 2x7. Since n is odd and a is positive, the end behavior is up and down.
The end behavior of the graph is since the first end drops and the second rises in this case.
The degree and leading coefficient of a particular polynomial's graph will be used to analyze its final behavior.
The right answer is C: "[tex]2x^{7}[/tex] is the leading phrase. As an is positive and n is odd, the final behavior is down and up."
The general principle to remember is:
The polynomial's two arms move in the same direction if the degree is even, and both ends move upward if the leading coefficient is positive.
Both ends fall if the leading coefficient is negative.
Each end points in a separate directions if the degree is odd.
The first end (the one with the negative values) goes down and the other end goes up if the leading coefficient is positive.
The opposite occurs when the leading coefficient is negative.
This is the polynomial:
p(x)= [tex]2x^{7} -8x^{6} -3x^{5} -3[/tex]
The degree is 7, therefore it is odd, and the leading coefficient is positive, as can be seen (is equal to 2).
The correct response is C since the first end drops and the second rises in this case.

find the perimeter of J(-4,2), K(1,2), L(2,-2) and M(-3,-2)
Answer:
Perimeter = 31.12
Step-by-step explanation:
The perimeter of the shape JKLM will be expressed as;
Perimeter = JK + JL + JM + KL + KM + LM
Using the formula for calculating the distance between two points;
D = √(x2-x1)²+(y2-y1)²
For JK where J(-4,2) and K(1,2)
JK = √(1+4)²+(2-2)²
JK = √5²
JK =√25
JK = 5
For JK where J(-4,2) and L(2,-2)
JL = √(2+4)²+(-2-2)²
JL = √6²+(-4)²
JL =√36+16
JL = √52
For JM where J(-4,2) and M(-3,-2)
JM = √(-3+4)²+(-2-2)²
JM = √1²+(-4)²
JM =√1+16
JM = √17
For KL where K(1,2), L(2,-2)
KL = √(2-1)²+(-2-2)²
KL = √1²+(-4)²
KL =√1+16
KL = √17
For KL where K(1,2), M(-3,-2)
KM = √(-3-1)²+(-2-2)²
KM = √4²+(-4)²
KM = √16+16
KM = √32
KM = 4√2
For KL where L(2,-2) and M(-3,-2)
LM = √(-3-2)²+(-2+2)²
LM = √(-5)²+(0)²
LM = √25
LM = 5
Perimeter = 5 + 4√2 + √17 + √17 + 5 + √52
Perimeter = 10 + 4√2 + 2√17 + √52
Perimeter = 10+5.66+8.25+7.21
Perimeter = 31.12

The slope is -10, and the y-intercept is -1.
The slope is -10. and the y-intercept is 1
The slope is -1, and the y-intercept is -10.
The slope is 1, and the y-intercept is -10.
Save and Exit
Answer:
The slope is -10, and the y-intercept is -1.
Step-by-step explanation:
The linear function is [tex]y=-10x-1[/tex].
The general form of a line is [tex]y=mx+c[/tex]
where
m = Slope of the line i.e., change of altitude divided by the change of the horizontal.
c = y intercept of the line i.e., the point where the line intersects the y axis.
Comparing with the given equation we get
[tex]m=-10[/tex] and [tex]c=-1[/tex]
So, the slope is [tex]-10[/tex], and the y-intercept is [tex]-1[/tex].

Answer:
False
Step-by-step explanation:
This graph is not a function because it fails the vertical line test where you draw a vertical line through the graph and if the vertical line touches the graph more than once it fails the vertical line test which means it is not a function.

If each fold doubles every time you fold it and its already fold to 0.04 cm it would be doubled if you fold it again so it would be 0.08 cm.

Why negative ( - ) sign is cannot be pulled out of square root.???
To show the negative of a square root, a negative sign would have to be placed outside the radical.
Answer:
Step-by-step explanation:
Because √-1 is an imaginary number √-1=i
They are imaginary because there are no same real numbers multiplyed that gives you a negative number
√4 = √2*2 ( +2*+2 =+4)
√4 = √-2*-2 (-2*-2 =+4)
√-1 = √? *? ( what same numbers multiplied gives you negative?...an imaginary one)
A manufacturer of fuses claims that with 20% overload, the fuses will blow
in less than 10 minutes on the average. To test this claim, a random sample of 20 of
these fuses was subjected to a 20% overload, and the times it took them to blow had
the mean of 10.4 minutes and a sample standard deviation of 1.6 minutes. It can be
assumed that the data constitute a random sample from a normal population. Do they
tend to support or refute the manufacturer’s claim?
Using the t-distribution, it is found that since the p-value of the test is greater than the standard significance level of 0.05, the data refutes the manufacturer's claim.
What are the hypothesis tested?At the null hypothesis, we test if there is not enough evidence that the mean is less than 10 minutes, that is:
[tex]H_0: \mu \geq 10[/tex]
At the alternative hypothesis, we test is there is enough evidence that the mean is less than 10 minutes, that is:
[tex]H_1: \mu > 10[/tex]
What is the test statistic?The test statistic is given by:
[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]
The parameters are:
[tex]\overline{x}[/tex] is the sample mean.[tex]\mu[/tex] is the value tested at the null hypothesis.s is the standard deviation of the sample.n is the sample size.The values of the parameters are given as follows:
[tex]\overline{x} = 10.4, \mu = 10, s = 1.6, n = 20[/tex]
Hence the test statistic is:
[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]
[tex]t = \frac{10.4 - 10}{\frac{1.6}{\sqrt{20}}}[/tex]
t = 1.12.
What is the p-value?Using a t-distribution calculator, considering a left-tailed test, as we are testing if the mean is less than a value, with t = 1.12 and 20 - 1 = 19 df, the p-value is of 0.8617.
Since the p-value of the test is greater than the standard significance level of 0.05, the data refutes the manufacturer's claim.
