Answer:
A function f:R→R is periodic if there exists some number t>0 such that
f(x)=f(x+t)
A constant function is periodic since you can take t=1,t=2, etc. (Hint: Hover over the tag "periodic-functions". What do you see?)
The fundamental period of f is the smallest of such t's. Since t cannot be 0, you are looking for the minimum of (0,∞), which does not exist.

If you are traveling in your car at an average rate of r miles per hour for T hours, then the distance d in miles that you travel is described by the formula d=rt that is distance equals rate times time. A distance of 60 miles at an average rate of 40 miles per hour is covered in ___ hours?
Answer:
1.5 hr
Step-by-step explanation:
d = rt
re-arrange to
d/r = t
60 miles / 40 miles/hr = 1.5 hr

Marisela wants to create a trophy in the shape of a rectangular
pyramid with volume 0.1875 cubic foot. Complete the descriptions
by writing in the missing measurements. 7.6.6
Design #1: pyramid height = 1.5 ft; base width = 0.75 ft;
Answer:
Volume of a rectangular pyramid:
[tex]V=\dfrac13lwh[/tex]
where:
[tex]V[/tex] = volume[tex]l[/tex] = length of base[tex]w[/tex] = width of base[tex]h[/tex] = heightGiven:
[tex]V[/tex] = 0.1875 ft³[tex]w[/tex] = 0.75 ft[tex]h[/tex] = 1.5 ftSubstitute given values into the formula and solve for [tex]l[/tex]:
[tex]\implies 0.1875=\dfrac13 \cdot l \cdot 0.75 \cdot 1.5[/tex]
[tex]\implies 0.1875=\dfrac{1.125}{3} l[/tex]
[tex]\implies 0.1875=0.375 l[/tex]
[tex]\implies l=\dfrac{0.1875}{0.375}[/tex]
[tex]\implies l=0.5[/tex]
Therefore, the base length is 0.5 ft

Take some points
2x+3y<63y<-2x+6y<-2/3x+2As here < sign present line will be dashed and shading should be done below the line
So
(1,1)(1,0)(2,0)(-1,2)Graph attached
Answer:
Given inequality
[tex]\sf 2x + 3y < 6[/tex]
Rearrange to make y the subject
[tex]\sf \implies 2x + 3y < 6[/tex]
Subtract 2x from both sides:
[tex]\sf \implies 3y < -2x + 6[/tex]
Divide both sides by 3:
[tex]\sf \implies y < -\dfrac23x + 2[/tex]
When graphing inequalities
If the inequality sign is < or > then the line of the graph should be dashed.
If the inequality sign is ≤ or ≥ then the line of the graph should be solid.
If y < (less than) then the shading is below the line.
If y > (more than) then the shading is above the line.
Therefore, as the inequality is y < the line should be dashed and the shading should be below the dashed line.
To plot the line, substitute x = 0 and x = 3 into the equation:
[tex]\sf \implies -\dfrac23(0) + 2=2[/tex]
[tex]\sf \implies -\dfrac23(3) + 2=0[/tex]
Therefore, plot points (0, 2) and (3, 0). Draw a dashed straight line through the points. Shade below the dashed line.

Answer:
B
Step-by-step explanation:
x² - 8x + 97 = 0
the general form to solve such quadratic equations is
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case
a = 1
b = -8
c = 97
so, we get
x = (8 ± sqrt((-8)² - 4×1×97))/(2×1) =
= (8 ± sqrt(64 - 388))/2 = (8 ± sqrt(-324))/2 =
= (8 ± sqrt(324×-1))/2 = (8 ± 18×i)/2 = 4 ± 9i

Solve the following system of equations algebraically:
x + 5y = -19
3x - y=-9
Answer:
x= -4, y=-3
Step-by-step explanation:
solving the two equations simultaneously you'll get x to be-4 and y to be -3
x+ 5y= -19
3x-y=-9
multiplying the second equation by5
15x-5y=-45
adding eqn 1 and eqn 3
16x= -64
x= -4
substituting into eqn 2
3(-4)-y= -9
-y= -9+12
-y= 3
y=-3

Find the length of segment AD. Consider all possibilities.
So far, I've only gotten 7, 5, and 1. But I know there is one left. Can you guys help?
The points A, B, C and D are collinear points
The length of the segment AD is 7 units
How to determine the length AD?The given parameters are:
AB = 1
BC = 2
CD = 4
Because the points are on the same line, then the following is the possible equation
AD = AB + BC + CD
Substitute known values
AD = 1 + 2 + 4
Evaluate the sum
AD = 7
Hence, the length of the segment AD is 7 units

[tex]\frac{9}{10}[/tex]
Step-by-step explanation:
first we write 1 4/5 as an improper fraction:
[tex]1 \frac{4}{5}=\frac{5}{5}+\frac{4}{5}=\frac{5+4}{5}=\frac{9}{5}[/tex]
Now we multiply :
[tex]\begin{aligned}1 \frac{4}{5} \times \frac{1}{2} &=\frac{9}{5} \times \frac{1}{2} \\&=\frac{9 \times 1}{5 \times 2} \\&=\frac{9}{10}\end{aligned}[/tex]
$8400 is deposited at an APR of 5%. How much interest has been accrued after 6 years ?
Answer:
$2,856.80
Step-by-step explanation:
The formula for the balance of an account earning interest compounded annually is ...
A = P(1 +r)^t . . . . where P is the principal invested at annual rate r for t years
__
Using the given values, we find the account balance to be ...
A = $8400(1 +0.05)^6 ≈ $11,256.80
The excess over the initial investment is the interest earned:
$11,256.80 -8,400 = $2,856.80
The account has accrued $2,856.80 in interest after 6 years.
_____
Additional comment
If the account earns simple interest, it is computed using ...
I = Prt = $8400(0.05)(6) = $2,520
