Answers
Answer:
This is a simple multiplication problem.
Here is my steps:
(14x^3 + 35x^2 + 4x + 10x + 8x + 20)
Combine like terms:
(14x^3 + 35x^2 + 22x + 20)
And that is your answer^^
Answer:
14x3+ 39x2 +8x +20
Step-by-step explanation:
Use the distributive property and/or the FOIL (front, outer, inner, last) method.
First:
Multiply (7x2)(2x)
=14x3
Then (7x) (5)
=35x2
Second:
Multiply (2x)(2x)
=4x2
Then (2x)(5)
=10
Third:
Multiply 4(2x)
=8x
Then (4)(5)
=20
You should get:
14x3 +35x2 +4x2 +10 +8x +10
Add all common numbers.
You should get:
14x3+ 39x2 +8x +20

x/5 = 13
Multiply each side by
x/5 *5 = 13*5
x = 65
Answer:
x=65
Step-by-step explanation:
x/5+4=17
solve for x by simplifying for both sides of the equation, then isolate the variable. x=65

Round 8,503 to nearest thousand
Answers
Answer:
9,000
Step-by-step explanation:
If x < 5, we round down.
If x ≥ 5, we round up.
Since 8,503, 500 is ≥ 5, we round up to 9. So,
8,503 ≈ 9,000
Answer:
9,000
Step-by-step explanation:
Look to the hundreds place. If the number is 4 or below we round down. If the number is 5 or above we round up.The number is 5, so we round up. The 8 in the thousands place becomes a 9, and the other places become 0s. Write out the newly rounded number: 9,000You're done! I hope this helps!
State how many imaginary and real zeros the function has.
f(x) = x4 - 15x2 - 16
Answers
Answer:
2 real roots
2 imaginary roots
Step-by-step explanation:
So we have the function:
[tex]f(x)=x^4-15x^2-16[/tex]
And we want to find its zeros.
First, let u equal x². So:
[tex]0=u^2-15u-16[/tex]
Factor:
[tex]0=(u-16)(u+1)[/tex]
Zero Product Property:
[tex]u-16=0\text{ or }u+1=0[/tex]
Add 16; Subtract 1. Replace u:
[tex]x^2=16\text{ or }x^2=-1[/tex]
Take the square root:
[tex]x=\pm 4\text{ or }x=\pm i[/tex]
So, our solutions are 2 real roots and 2 imaginary roots.

Answers
Answer: x=52/3
Step-by-step explanation:
x+2/3=18
x=18-2/3 ⇔ subtraction property of equality
x=54/3-2/3 ⇔ convert integer into fraction
x=52/3
Hope this helps!! :)
Answer:
see below
Step-by-step explanation:
( x+2)/3=18
Multiply each side by 3
(x+2)/3 *3 = 18*3
x+2 = 54
Subtract 2
x+2-2 =54-2
x = 52
or if
x+2/3=18
Subtract 2/3
x+2/3 -2/3 = 18-2/3
x = 17 +1 -2/3
x = 17 1/3

Segment bisector: JK
MN= 52
Step-by-step explanation:
The segment bisector basically means the point where the line is cut in half. If you study the figure, you can see the two small red lines intersecting The longer line. This means that the two small black segments are equal to each other. With this in mind, we now know that the segment bisector is line JK.
To find the length of MN, study the figure again. You can see that we are given the value of one line segment that is half the length of MN. So all we need to do is multiply that value by 2:
[tex]26*2=52[/tex]
The length of line segment MN is 52.
:Done
Answer:
MN = 52
Step-by-step explanation:
bisector is just a half of its length
looking through the graph
MN = 26 * 2 (just multiply ot by 2)
MN = 52

The average natural gas bill for a random sample of 26 homes in the 19808 zip code during the month of March was $305.30 with a sample standard deviation of $46.50. The critical value for a 95% confidence interval around this sample mean is ________.
Answers
Answer:
2.06
Step-by-step explanation:
The formula for critical value = Margin of Error / Standard Error
Margin of Error = z × Standard deviation/√n
Mean for the month of March = $305.30
Standard deviation = $46.50
n = number of samples = 26 homes
z score for 95% confidence interval = 1.96
= 1.96 × $46.50/√26
= 17.874024556
Standard error = standard deviation/√n
= $46.50/√26
= 9.1194002839
Critical value = Margin of Error/Standard Error
= 17.874024556/9.1194002839

The question is incomplete.
The complete question is:
Determine if the function is a polynomial function. If the function is a polynomial function, state the degree and the leading coefficient. If the function is not a
polynomial, state why.
F(x) = 1,050
A. This is a polynomial function of degree zero with a leading coefficient of 1,050.B. This is not a polynomial. Horizontal lines can not be polynomials as there are no turning points.C. This is not a polynomial. Only vertical lines of the form x = b can be classified as a polynomial.D. This is not a polynomial because there are no variables.We have a function:
f(x) = 1050
We can write it as:
f(x) = 1050x⁰
x⁰ = 1
As we know from the definition of the polynomial:
The polynomial is a combination of the variable and constant with powers of x that are non-negative.
f(x) = 1050 is a polynomial function of degree zero with a leading coefficient of 1,050.
Thus, the function f(x) = 1050 is a polynomial with degree zero option (A) this is a polynomial function of degree zero with a leading coefficient of 1,050 is correct.

Find the area of a circle with diameter 15cm
Answers
Answer:
177 cm²
Step-by-step explanation:
Area of circle = [tex]\pi[/tex]r²
Radius = diameter/2 = 15/2 = 7.5
Therefore,
Area = 22/7 × 7.5 × 7.5
= 176.7 = 177 cm²
Answer:
The answer is
176.71 cm²Step-by-step explanation:
Area of a circle is given by πr²
where
r is the radius
From the question we were given the diameter
To find the radius using the diameter we use the relation
[tex]radius = \frac{diameter}{2} [/tex]
diameter = 15 cm
[tex]radius = \frac{15}{2} [/tex]
radius = 7.5 cm
Substitute the value into the above formula and solve for the area
Area = (7.5)²π
= 56.25π
= 176.714586
We have the final answer as
176.71 cm² to 2 decimal places

the midpoint of a horizontal line segment is at x=1 if the length of the line segment is 10.5. what absolute value equation could be used to find the x value of the endpoints
Answers
Answer: -4.25 ≤ x ≤ 6.25
Step-by-step explanation:
The midpoint of a segment is located at the same distance of each of the endpoints of the segment.
The midpoint is at x = 1.
The length of the segment is 10.5, if we divide it by two we have:
10.5/2 = 5.25
Now, if we want the endpoints to be at the same distance of the midpoint, then the endpoints will be:
Xmax = midpoint + 5.25
Xmin = midpoint - 5.25
Then the extremes are:
Xmax = 1 + 5.25 = 6.25
Xmin = 1 - 5.25 = -4.25
Then this segment can be written as:
Xmin ≤ x ≤ Xmax
-4.25 ≤ x ≤ 6.25
