Answer:
A. The height of the ball is the same after 1 second and 3 seconds.
Step-by-step explanation:
The quadratic equation function modeling is used to analyze the relationship between variables in the equation. If the ball is at height and t is time then the ball is on symmetric line which will move for initial 1 second then stabilizes at 3 seconds.
Sherry is paid an annual salary of $26,000 biweekly. Her friend Donna makes the same salary but is paid quarterly. How much more money does one of Donna's checks have than Sherry's.
Answer:
5000
Step-by-step explanation:
Assuming they both work 365days
roughly 52 weeks
number of time sherry is paid per year = [tex]\frac{52}{2} = 26[/tex]
because she is paid every two weeks
number of time donna is paid per year = [tex]4[/tex]
because she is paid 4 times a year (quarterly)
let s = amount sherry is paid biweekly
let d = amount donna is paid quarterly
[tex]s = \frac{26000}{26} = 1000\\\\d = \frac{26000}{4} = 6500\\\\difference = 65000 - 1000 = 5000\\[/tex]

-6K – 3 = 39. Please solve this equation for K. Type your work in.
Answer:
k = -7
Step-by-step explanation:
-6k-3 = 39
Add 3 to each side
-6k-3+3 = 39+3
-6k = 42
Divide each side by -6
-6k/-6 = 42/-6
k = -7

How would you graph y = -4/9x + 6
9514 1404 393
Answer:
graph the y-interceptfind another point (down 4, right 9)draw the line through the 2 pointsStep-by-step explanation:
When the equation of a line is given in slope-intercept form, as this one is, it is usually convenient to make use of those values (intercept and slope).
Here, the y-intercept is 6. The slope is -4/9, which means the line goes down 4 units for each 9 units to the right.
The y-intercept is graphed at (0, 6). An additional point can be graphed at (9, 2). Then the line can be drawn through these points.

Answer:
$609.50
Step-by-step explanation:
A = P(1 + r/n)^nt
= 500(1 + [tex]\frac{.04}{2}[/tex])^2(5)

Use the product rule to answer each of the questions below. Throughout, be sure to carefully label any derivative you find by name. It is not necessary to algebraically simplify any of the derivatives you compute.
a. Let m (w) = 3 w^17 4^w. Find m ′(w) .
b. Let h (t) = ( sin (t) + cos (t)) t 4. Find h ′(t).
c. Determine the slope of the tangent line to the curve y = f (x) at the point where a = 1 if f is given by the rule f(x) = e^x sin (x).
d. Find the tangent line approximation L(x) to the function y = g (x) at the point where a = − 1 if g is given by the rule g (x) = ( x^2 + x ) 2^x .
Answer:
A) M'(w) = w^16 * 4^w [ 51 + 3w In4 ]
B) h'(t) = [ cos (t) - sin (t) ] t^4 + [ sin(t) + cos (t) ] 4t^3
C) f'(1) = e' [sin(1) + cos(1) ]
D) g'(a) = 0 - 1/2
L(x) = - 1/2 ( x + 1 )
Step-by-step explanation:
Attached below is the detailed solution of the problem
A) m(w) = 3w^17 * 4^w
M'(w) = w^16 * 4^w [ 51 + 3w In4 ]
B) h(t) = [sin(t) + cos(t) ] t^4
h'(t) = [ cos (t) - sin (t) ] t^4 + [ sin(t) + cos (t) ] 4t^3
C) f(x) = e^x sin (x). at a = -1
f'(1) = e' [sin(1) + cos(1) ]
D) g (x) = ( x^2 + x ) 2^x .
g'(a) = 0 - 1/2
L(x) = - 1/2 ( x + 1 )

Area =
44 ft?
(x - 12) ft
(x - 5) ft
length:
width:
ft
Answer:
x= 16 ft
length = 4 ft
width = 11 ft
Step-by-step explanation:
The area is length* width
so the length is ( x - 12 )
and the width is ( x - 5 )
the area is 44ft
so now set up an equation and solve for x
( x - 12 ) ( x - 5 ) = 44
distribute
x^(2) - 17x + 60 = 44
inverse operations
x^(2) - 17x + 60 = 44
- 60 - 60
x^(2) - 17x = -16
factor
x^(2) - 17x = -16
x ( x - 17 ) = -16
now it is pretty clear that the answer is:
x = 16
just substitute it into the equation and check
( x - 12 ) ( x - 5 ) = 44
( 16 - 12 ) ( 16 - 5 ) = 44
( 4 ) ( 11 ) = 44
44 = 44
this also shows that
the length is 4
because:
( x - 12 )
= ( 16 - 12 )
= 4
and the width is 11
because:
( x - 5 )
= ( 16 - 5 )
= 11

Write an equation of the line passing through the point (8, -5) that is parallel to the line 2x -6y = -3
Answer:
y=1/3x+10.5
Step-by-step explanation:
y=mx+b, the equation of the parallel line is y=1/3x+1/2. So we know the slope is 1/3 and all we need is the Y intercept (b). We can find that manually with arithmetic because we know the slope. It turns out to be 10.5
find a function r(t) that describess the curve where the following surfaces intersect. answere are not unique x^2 y^2
Complete Question
find a vector function that represents the curve of intersection of the two surfaces. The cylinder [tex]x^2+y^2= 36[/tex] an the surface [tex]z=xy[/tex]
Answer:
The function is [tex]r(t) = 6cos(t) \ i + 6sin (t) \ j + 36costsint \ k[/tex]
Step-by-step explanation:
From the question we are told that
The equation of the cylinder is [tex]x^2+y^2= 36[/tex]
The equation of the surface is z = xy
Generally the general form of this function is
[tex]r(t) = x(t)i + y(t)j + z(t) k[/tex]
Generally to confirm the RHS and the LHS of the equation for the cylinder
Let take x (t) = 6cos(t)
and y(t) = 6sin (t)
So
[tex]x^2 + y^2 = [ 6cos(t)]^2 + [6 sin (t)]^2[/tex]
=> [tex]x^2 + y^2 = 6^2 cos^2t + 6^2 sin ^2t[/tex]
=> [tex]x^2 + y^2 = 6^2 [cos^2t + sin ^2t] [/tex]
Generally [tex]cos^2t + sin ^2t = 1[/tex]
So
[tex]x^2 + y^2 = 36[/tex]
So at x (t) = 6cos(t) and y(t) = 6sin (t) the RHS is equal to LHS
So
[tex]z(t) = x(t) * y(t)[/tex]
[tex]z(t) = (6 cos(t)) * (6 sin(t))[/tex]
=> [tex]z(t) =36costsint[/tex]
So the function is
[tex]r(t) = 6cos(t) i + 6sin (t) j + 36costsint k[/tex]
