What should n be if f (x) = x^n defines a polynomial function?
9514 1404 393
Answer:
a non-negative integer
Step-by-step explanation:
Powers of variables in a polynomial are whole numbers, that is, non-negative integers.
For f(x) to be a polynomial function, the value of n must be a whole number.
As a volunteer for the Boys and Girls Club, you and your fellow volunteers have been asked to help the students complete a model rocket project. Your plan is to fire the model rockets from the top of the building (175 ft tall) so that the rockets will clear the nearby trees. Neglecting air resistance, each rocket's height s (in feet) can be modeled with the equation s=−16t2+670t+175 where t is time (in seconds). Determine at what time the rockets will land so that your fellow volunteers can collect them and return them to the kids. Round to the nearest hundredth.

Step-by-step explanation:
In the diagram shown, it is known that RP is perpendicular to QS and RP bisects angle SRQ. If angle SRQ is 104 degrees, then explain why angle S is 38 degrees. pls help
Answer/Step-by-step explanation:
Since RP is perpendicular to QS, the angle formed is a right angle, therefore,
m<SPR = 90°
Since RP bisects <SRQ, which measures 104°, therefore,
m<SRP = ½*104°
m<SRP = 52°
m<S + m<SPR + m<SRP = 180° (sum of ∆)
m<S + 90° + 52° = 180° (substitution)
m<S + 142° = 180°
Subtract 142 from each side
m<S = 180° - 142°
Therefore:
m<S = 38°
Angles in a triangle may or may not be congruent.
[tex]\mathbf{\angle S}[/tex] is 38 degrees because [tex]\mathbf{\angle S}[/tex] is one of the base angles of an isosceles triangle.
From the question, we have:
[tex]\mathbf{\angle SRQ = 104^o}[/tex]
The sum of angles in a triangle is 180.
So, we have:
[tex]\mathbf{\angle SRQ + \angle S + \angle Q = 180}[/tex]
and
[tex]\mathbf{\angle S = \angle Q }[/tex] --- base angles of an isosceles triangle.
So, we have:
[tex]\mathbf{104 + \angle S + \angle S = 180}[/tex]
Subtract 104 from both sides
[tex]\mathbf{2\angle S = 76}[/tex]
Divide both sides by 2
[tex]\mathbf{\angle S = 38}[/tex]
Hence, [tex]\mathbf{\angle S}[/tex] is 38 degrees because [tex]\mathbf{\angle S}[/tex] is one of the base angles of an isosceles triangle.

Which answer choice shows 7.68 rounded to the nearest half?
A. 7
B. 7.5
C. 8
D. 8.5
Answer:
B. 7.5
Step-by-step explanation:
The number 7.68 is between 7.5 and 8. Let's find which of those two numbers 7.68 is closer to. We can do this by subtracting 7.68 from each of those numbers:
8 - 7.68 = 0.32
7.5 - 7.68 = -0.18
7.68 is 0.32 away from 8, but it's only 0.18 away from 7.5. So, the nearest half is 7.5.
I hope this helps :)

Hi guys, I need help to solve this. I can’t understand how the percentage is calculated in (a) and (b) and how the rent is calculated in (c) because we have no numbers given.
Answers :
(A) 18.33%(B) 21.65%(C) about 173.33(D) i really have no way of finding the angles for you, you could try to find them yourself; or maybe just leave it blank?OK, so judging from the bar shown :It looks like Rent takes up 1/3 of the space so 33.33..%
It also looks like Loan Repayment + Savings is another 33.33..% but Savings is slightly larger than Loan Repayment so you could just estimate Savings to be 55% and LR to be 45% of the 1/3 space.
55% of 33.33.. = 18.33%45% of 33.33.. = 14.99%LR looks equal to Entertainment making it another 14.99.
It also looks like Entertainment + Electricity + Groceries = the last 33.33..%
And since we know Entertainment = 14.99 / 45% of 33.33..
Making Electricity and Water ABOUT 35% of 33.33... which is 11.66
And Groceries is somehow 20% of 33.33 = 6.66
Rent = 33.33..%Savings = 18.33%Loan Repayment 14.99%Entertainment 14.99%Electricity and Water 11.66%Groceries = 6.66%All of these added together equal ABOUT 100%
Three local gyms are having membership specials.
Able Bodies is offering memberships for $32.95 per month.
Health Styles is offering an 18-month membership for $359.82.
Crossfit Express is offering a 12-month membership for $299.40.
Which gym is offering the lowest price per month?
Which gym is offering the highest price per month?
Answer:
Lowest: Health Styles
Highest: Able
Able is 32.95$ per month
Health Styles is 20$ per month
Crossfit is 24.95 per month
So, Health is the lowest and Able is the highest.
I figured this out by divided the amount by the amount of months. For example, 359.82 divided by 18 is 19.99 which is also the amount per month.

What is the sum of the measures of the interior angles of an octagon?
A. 2160°
B. 1440
C. 45°
D. 2880°
E. 1080°
F. 360°
Answer:
Answer E is correct
Step-by-step explanation:
An octagon has 8 sides.
So, in the question, they're asking for the sum of measures of the interior angles.
For that, you can use the below formula.
Sum of the measures of the interior angles in a polygon = 180 ( n - 2 )
Here,
n ⇒ number of sides
Let us solve it now.
180 ( n - 2 )
180 ( 8 - 2 )
180 × 6
1080°

Benson purchased a $1,800 certificate of deposit that earns simple annual interest. At the end of 1 year, the certificate was worth $1,857.60.
Answer:
3.2%Step-by-step explanation:
Step one:
given data
principal P= $1800
time t= 1 year
Final amount A=1857.60
rate r=?
Step two:
we are expected to solve for the rate, let assume the investment is a simple interest type.
A=P(1+rt)
solve for r we can substitute our data
1857.60=1800(1+r*1)
1857.60=1800+1800r
1857.60-1800=1800r
57.6=1800r
r=57.6/1800
r=0.032
0.032*100= 3.2%
This shows that the rate is 3.2%

The graph represents in the graph is f(x) = {x +1 for x < 1, 5 for 1 < x < 4, and x - 1 for x ≥ 4} thus option (B) is correct.
What is a graph?The graph is a geometrical representation of a function and can be plotted by taking x's and y's corresponding values within the interval.
For example plot of y = x³ ,y = sinx.
As per the given graph of a piecewise function.
The first line has a range before x = 1 so x < 1 will be the domain.
The second line is f(x) = 5 for the internal 1 < x < 4 (since the hollow dot represents that 1 and 4 are not present).
The third line has a domain of x ≥ 4 (due to the solid dot).
Hence "The graph represents in the graph is f(x) = {x +1 for x < 1, 5 for 1 < x < 4, and x - 1 for x ≥ 4}".

13) m-30=10
Answer:
12. q = -26
13. m = 20
Step-by-step explanation:
12.
q + 11 = -15
q = -15 - 11
-26 - 11 = -15
13.
30 - m = 10
m = 30 - 10

Step-by-step explanation:
I dont really have an explanation i just know this is the answer. I am on this problem too lol
Translated 1 unit right and 2 units up followed by a reflection across x-axis.
Given that, a parallelogram with vertices A(−2, 1), B(−4,−3), C(2,−5), and D(4,−1).
We need to find which sequence of transformations will result in a parallelogram with vertices.
What is a transformation?A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or a geometric figure. The original shape of the object is called the pre-image and the final shape and position of the object is the image under the transformation.
Parallelogram has vertices A(−2, 1), B(−4,−3), C(2,−5), D(4,−1) while parallelogram A'B'C'D' has vertices A'(-1, -3) B'(-3, 1) C'(3, 3) D'(5, -1)
If a point X(x, y) is translated a units right and b unit up, the new point is X'(x + a, y + b).
If a point X(x, y) is reflected across the x-axis, the new point is X'(x, -y)
If parallelogram ABCD is translated 1 unit right and 2 units up (i.e. x + 1, y + 2), the new points is A'(-1, 3), B'(-3, -1), C'(3, -3), D'(5, -1). If a reflection across x-axis is then done, the new point is A'(-1, -3) B'(-3, 1) C'(3, 3) D'(5, -1)
Hence, translated 1 unit right and 2 units up followed by a reflection across x-axis.
