A customer tells you that they will call at 3PM Eastern Standard Time. If you are located in the Pacific Standard Time Zone (which is 3 hours earlier), when should you expect the call?
Answers
Answer:
At midday. In a 24 hours clock, 12:00, in a midday format 12 PM.
Step-by-step explanation:
In order to calculate this you just have to withdraw the hour difference between both the Eastern Standar Time and the Pacific Standar Time, which normally are 3 hours of difference, since he is in the Eastern Standar Time, that means he is 3 hours ahead of you, so in order to calculate the hour at which you should expect the call, you have to withdraw 3 hours frmo 3 P.M which would make it midday or 12 P.M
Write a polynomial expression for the perimeter of a rectangle whose sides have the following lengths. Length: x2+3x-5 Width: 3x2-2x+6 A. 8x2+8x+2 B.8x2+2x+2 C.4x2+x+1 D. 4x2-5x+1
Answers
Final answer:
The perimeter of the rectangle with given dimensions is represented by the polynomial 8x^2 + 2x + 2, which corresponds to option A.
Explanation:
To determine the perimeter of a rectangle, we need to add up all sides of the rectangle. The formula for the perimeter (P) of a rectangle is P = 2(length) + 2(width). Given the length is x2 + 3x - 5 and the width is 3x2 - 2x + 6, we would calculate the perimeter as follows:
P = 2(x2 + 3x - 5) + 2(3x2 - 2x + 6)
Expanding this expression:
P = 2x2 + 6x - 10 + 6x2 - 4x + 12
Combining like terms gives us:
P = (2x2 + 6x2) + (6x - 4x) + (-10 + 12)P = 8x2 + 2x + 2
So the correct polynomial expression for the perimeter of the rectangle is option A: 8x2 + 2x + 2.
Final answer:
The polynomial expression for the perimeter of the rectangle with given side lengths is 8x^2 + 2x + 2.
Explanation:
The perimeter of a rectangle is given by the formula P = 2l + 2w, where l represents the length and w represents the width. For the lengths provided, the length (l) is x2 + 3x - 5 and the width (w) is 3x2 - 2x + 6. To find the polynomial expression for the perimeter, we will multiply both the length and the width by 2 and then sum them:
Perimeter (P) = 2(x2 + 3x - 5) + 2(3x2 - 2x + 6)
On simplifying:
P = 2x2 + 6x - 10 + 6x2 - 4x + 12
P = (2 + 6)x2 + (6 - 4)x - (10 - 12)
P = 8x2 + 2x + 2
Therefore, the correct polynomial expression for the perimeter is 8x2 + 2x + 2, which corresponds to option B.

It is 76 miles from waterton to middleton. it is 87 miles from middleton to oak hill. driving directly, it is 134 miles from waterton to oak hill. it is 39 miles rom oak hill to jackson. if juan drives from waterton to middleton then from middleton to oak hill, and finally home to waterton, how many miles does he drive?
Answers
Juan drives a total of 297 miles if he travels from Waterton to Middleton, then to Oak Hill, and back to Waterton.
Explanation:The student is asking to calculate the total number of miles driven by Juan starting from Waterton to Middleton, then from Middleton to Oak Hill, and then returning home to Waterton.
To find the total distance traveled by Juan, we simply need to add the individual distances of each leg of his trip.
Waterton to Middleton: 76 milesMiddleton to Oak Hill: 87 milesOak Hill to Waterton (directly): 134 milesBy adding these distances, we get the total miles Juan drives:
Total miles driven = 76 + 87 + 134 = 297 miles
How far does a ball, hit from a height of 3 feet at a speed of 120 feet per second and an angle of 30 degrees, go before it hits the ground? Round your answer to the nearest integer.
Answers
h = h0 + vi*t - 0.5gt^2 = 3 ft + (60 ft/s)(1.875 s) - 0.5(32 ft/s^2)(1.875)^2 = 59.25 ft
So the time of its downward flight is solved by:
59.25 = 0.5(32)t^2
t = 1.924 s
Total time of flight = 1.875 + 1.924 = 3.799 s
The ball's horizontal velocity is constant at (120 ft/s)(cos 30) = 103.923 ft/s.
Multiplying this by the time of flight of 3.799 s gives a total distance of 395 ft.

yes, 10^9+10^8+10^7 is divisible by 555
The proof that 10⁹ + 10⁸ + 10⁷ is divisible by 555; Is true and has been proved below
Divisibility of Numbers
Let the number N be expressed as;
10⁹ + 10⁸ + 10⁷
We can factor out 10⁷ to get;
⇒ 10⁷(100 + 10 + 1)
⇒ 10⁷(111)
⇒ 10 × 10⁶(111)
We can factorize 10 further to get;
5 × 2 × 10⁶(111)
⇒ 555 × 2 × 10⁶
Since the answer contains 555, then we can say that it is divisible by 555.

If the constant c is chosen so that the curve given parametrically by ct, c 2 16 t 2 , 0 ≤ t ≤ 3 , is the arc of the parabola 16y = x 2 from (0, 0) to (8, 4), find the coordinates of the point p on this arc corresponding to t = 2.
Answers
Final answer:
The coordinates of point p corresponding to t = 2 on the specified parametric curve, when matching the arc of the parabola 16y = x^2, are (8, 2).
Explanation:
The student is asking to find the coordinates of the point p corresponding to t = 2 on the curve defined parametrically by ct, [tex]c^2/16[/tex] × [tex]t^2[/tex] where c is chosen such that the curve becomes the arc of the parabola 16y = x² from (0, 0) to (8, 4).
To find c, we match the parametric equations to the standard form 16y = x², which implies c = 4 because for any point (x, y) on the parabola, y must equal [tex]x^2/16[/tex].
Substituting t = 2 into the corrected parametric equations x = 4t and y = 4 · [tex](t^2/16)[/tex], we obtain the coordinates of point p as (8, 2).

at an airport it costs $7 to park for up to one hour and $5 per hour for each additional hour. let x represent the number of hours parked. write the function that modles the cost, C(x), of the parking x hours, where x is an integer greater then 1.
Answers
Answer:
C(X) = 7 + 5(X-1)
Step-by-step explanation:
So, the cost for parking from 0 to 1 hour is $7. Then, for one extra hour, from 1 to 2, you have to pay an additional $5. For another hour, from 2 to 3, an extra $5, and so on. So, lets make a quick table:
Hours Cost
[0-1] $7
(1-2] $7+$5
(2-3] $7+$5+$5
(3-4] $7+$5+$5+$5
So, for 1 hour the cost is $7, for 2 hours $12, 3 hours $17, 4 hours $22, and so on. We can see a pattern here: the cost for X hours is $7 plus $5 for each hour greater than 1. So we can write the cost function as:
C(X) = 7 + 5(X-1)
If X=2, 2 hours, the cost is:
C(2) = 7 + 5(2-1) = 7 + 5 = 12, so the function fits.
Notice that here I used the parenthesis in a (--] form, however, it could also be used in a [--) form. If the last is chosen, 2 hours would cost $17 instead of $12. The function would be C(X) = 7 + 5X.
As the statement does not specifies, any of this ways can be used.

The fountain is made up of two semicircles and a quarter circle. Find the perimeter and the area of the fountain. Round the perimeter to the nearest tenth of a foot and the area to the nearest square foot. Both have the diameter 20
Answers
we know that
[area of a circle]=pi*r²
[length of the circumference]=2*pi*r
Part A)
(2 half circles=1 whoole circle)

[area 2 half circles]=pi*r²----> pi*10²----> 314.16 ft²
