teh velocity of a partilce in ft/s, moving along the x axis is given the function v(t) e^t te^t when 0
The magnitude of the acceleration of the particle is zero when the velocity of the particle is zero.
What is Acceleration ?
Acceleration is the rate of change of velocity. Usually, acceleration means the speed is changing, but not always. When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing.
Given,
Velocity v= x² − 5x + 4
now, the acceleration
a = dv/dt
a = 2x (dx/dt) - 5x(dx/dt)
given that, v= dx/dt =0
so, a = 2x*0−5*0
a=0 m/sec²
so, the acceleration is zero ,when the velocity is zero.
Hence ,The magnitude of the acceleration of the particle is zero when the velocity of the particle is zero.

a coin is flipped 10 times how many outcomes will have exactly 4 tails and start and end with different faces
There are a total of 2^10 = 1024 possible outcomes for a coin flipped 10 times. Out of these, there are only 10 outcomes that have exactly 4 tails and start and end with different faces.
To count the number of outcomes with 4 tails, we can use the binomial coefficient formula: n choose k = n!/(k! * (n-k)!), where n is the total number of flips (10 in this case) and k is the number of tails (4 in this case). This gives us 10 choose 4 = 10!/ (4! * 6!) = 210 outcomes with 4 tails.
To count the number of outcomes that start and end with different faces, we can consider the first and last flips separately. The first flip can be either heads or tails and the last flip can also be either heads or tails, for a total of 2 * 2 = 4 possibilities.
Thus, there are a total of 210 * 4 = 840 outcomes that have exactly 4 tails and start and end with different faces. However, there are two outcomes (THTHTHTHTHT and TTHTHTHTHTH) that are counted twice in this total, so we need to subtract these from the total to get the correct number of outcomes. This gives us 840 - 2 = 838 outcomes.
Finally, we need to subtract the two outcomes that start and end with the same face (HHHHHHHHTH and THHHHHHHHH). This gives us a total of 838 - 2 = 836 outcomes.
Therefore, there are a total of 836 outcomes that have exactly 4 tails and start and end with different faces out of a total of 1024 possible outcomes.

The midpoint of PR is (-6,9). P=(-15,4)
What are the coordinates of point R?
R=(_,_)
Answer:
R = (3, 14 )
Step-by-step explanation:
given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint M is
( [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] ) ← midpoint formula
calculate the midpoint of PR using this formula and equate x and y coordinates to the coordinates of the given midpoint
let coordinates of R be (x, y ) and P = (- 15, 4 ) , then
[tex]\frac{x-15}{2}[/tex] = - 6 ( multiply both sides by 2 )
x - 15 = - 12 ( add 15 to both sides )
x = 3
and
[tex]\frac{y+4}{2}[/tex] = 9 ( multiply both sides by 2 )
y + 4 = 18 ( subtract 4 from both sides )
y = 14
the coordinates R = (3, 14 )

A food company sells its corn flakes in boxes of two different sizes: the regular box and the family value box. For the family value box, the length, width, and height of the box have all been increased by 20%.
The volume expression for the box is 1.728lwh and it means that the volume increases by 72.8%
How to determine the volume expression for the box?The complete question is added at the end of this solution
From the question, we have the following parameters that can be used in our computation:
Length = l
Width = w
Height = h
The volume of a box can be calculated using
Volume = lwh
Rewrite the volume equation as
v = lwh
When the dimensions of the box are increased by 20%, we have the following expressions
Length = 1.2l
Width = 1.2w
Height = 1.2h
So, the new volume is
V = 1.2l * 1.2w * 1.2h
Evaluate
V = 1.728lwh
Hence, the expression is 1.728lwh

a,b)Find the phasor form of the following E-field, the polarization type, and plot the vector on the X-y axis (z-0) for one period a) E(z,t) = xZcos(wt kz) y4cos(wt kz) b) E(z,t) = R2cos(wt + kz) - 94sin(wt + kz)
a) The phasor form of E-field = xˆ 2cos(wt - kz) - yˆ 4cos(wt - kz) is 2√5 L(-63.43).
Polarization type is linearly polarised.
b) The phasor form of E-field = ?
E(z,t) = xˆ 2cos(wt + kz) - yˆ 4sin(wt + kz) is E(z,t) =2√5 L(-143.43). polarization type is elliptical.
We have given that
E⃗(z,t) =2xˆcos(wt - kz) - 4 yˆcos(wt - kz)
|r⃗ | = √((2cos(wt - kz))² + (- 4cos(wt - kz))²)
= √(4cos²(wt - kz) + 16cos²(wt - kz))
= √(20cos²(wt - kz))
= 2√5 cos(wt - kz)
φ = 4cos(wt - kz)/(2cos(wt - kz))
= tan⁻¹ 1(-2) = -63.43°
So, E(z,t) = 2√5 L(-63.43)
b) E(z,t) = xˆ 2cos(wt + kz) - yˆ 4sin(wt + kz)
= xˆ 2cos(wt + kz) - yˆ 4cos(wt + kz -π/2)
|r| = √((2cos(wt + kz))² + (- 4sin(wt -+kz))²)
= √20
phi = tan⁻¹(- 4cos(wt - kz)/(2cos(wt - kz)) - π/2
= tan⁻¹( -2) + π/2 = - 143.43
so, E(z,t) =2√5 L(-143.43)
E(z,t) = xˆ 2cos(wt - kz) - yˆ 4cos(wt - kz)
if wt = 0°
E(z,t) = xˆ 2cos(0 - kz) - yˆ 4cos(0- kz)
= 2xˆ - 4yˆ
wt = 30° , E(z,t) = xˆ 2cos( - kz) - yˆ 4cos(0- kz)
E(z,t) = √3/2(2) xˆ - √3/2(4) yˆ
= √3xˆ - 2√3yˆ
for wt = 45°
E(z,t) = √2 xˆ - 2√2 yˆ
for wt = 90° =>E(z,t) = 0
for wt = 60° , E(z,t) = xˆ - 2 yˆ as seen in above graph that is linear polarised
For part (b) ,
E(z,t) = 2 xˆcos(wt - kz) - 4yˆ sin(wt + kz)
From graph elliptical polarised,
for wt = 0 , E(0,t) = 2 xˆ
for wt = 90° , E(0,t) = -4yˆ
for wt =180° , E(0,t) = -2 xˆ
for wt = 270° , E(0,t) = -4yˆ
Hence, we get the answer of both parts.

Answer:
For the first one x= 60 degrees
Second one x= 125 degrees
Step-by-step explanation:
a) To figure out this we can see that the total of angles in a 5- angled shape is 540 degrees.
So (2x X 4) + x = 540 degrees
= 9x= 540
= x = 60
b) To figure out this we can see that the total of angles in a 7- angled shape is 900 degrees.
So 60+2x+x+x+x+x+90= 900
= 150 +6x= 900
= 6x= 750
= x= 125

Miguel is mailing packages.Each small package cost him $2.20 to send.Each large package cost him $3.90.How much will it cost him to send 6 small packages and 1 large package?
Answer: $13.50
Step-by-step explanation:
It will cost Miguel $13.50 to send 6 small packages and 1 large package. To find the total cost, we can first calculate the cost of sending the small packages by multiplying the cost per small package by the number of small packages: 2.20 * 6 = $<<2.20*6=13.20>>13.20
We can then add the cost of the large package to find the total cost: 13.20 + 3.90 = $<<13.20+3.90=17.10>>17.10.
Therefore, it will cost Miguel $17.10 to send 6 small packages and 1 large package.

David invests $800 into an account with a 2.3% interest rate that is compounded semiannually.
How much money will he have in this account if he keeps it for 5 years?
Round your answer to the nearest dollar.
To calculate how much money David will have in this account after 5 years, we first need to find out how much interest the account earns each year. To do this, we need to multiply the interest rate by the amount of money in the account. In this case, the interest earned each year would be $800 * 0.023 = $18.40.
Next, we need to calculate how much interest the account earns over the 5-year period. Since the interest is compounded semiannually, this means that the interest is earned twice per year. Therefore, the total amount of interest earned over 5 years would be $18.40 * 2 * 5 = $184.
Finally, we need to add the interest to the original amount of money in the account to find out how much money David will have after 5 years. In this case, the total amount of money David will have after 5 years is $800 + $184 = $984.
Therefore, if David keeps the money in this account for 5 years, he will have $984.
