the time, t, in seconds, is required for an object accelerating at a constant rate of a meters/second to travel a distance of d meters is given this equation
Answers
Answer:
C. [tex] d = \frac{at^2}{2} [/tex]
Step-by-step explanation:
Given:
[tex] t = \sqrt{\frac{2d}{a}} [/tex]
Required:
Make d the subject of the formula.
SOLUTION:
[tex] t = \sqrt{\frac{2d}{a}} [/tex]
Square both sides
[tex] t^2 = (\sqrt{\frac{2d}{a}})^2 [/tex]
[tex] t^2 = \frac{2d}{a} [/tex]
Multiply both sides by a
[tex] a*t^2 = \frac{2d}{a}*a [/tex]
[tex] at^2 = 2d [/tex]
Divide both sides by 2
[tex] \frac{at^2}{2} = \frac{2d}{2} [/tex]
[tex] \frac{at^2}{2} = d [/tex]
[tex] d = \frac{at^2}{2} [/tex]

1.) The Remainder Theorem states that if a polynomial is divided by (x – a), the remainder is the value of the function at a. So, if (x – a) is a factor of P(x), then P(a) = 0. Determine whether the given binomial is a factor of the polynomial P(x).
2.) if there is a remainder then it is not a factor
3.) x-2 divided by x^3+5x^2-2x+9
across you have

Jack bought a new boat for $36,000. The value of the boat continuously
depreciates at a rate of 15%. Find the value of the boat after 5 years.
a. $17,005
b. $7,621
c. $7,240
d. $4,140
Answers
Answer:
$15973.4
Step-by-step explanation:
The formula for depreciation is:
a(1 - r)^t
a = Initial value =$36,000
r = depreciation rate = 15% = 0.15
t = time in years = 5 years
The depreciation value = $36000 × (1 - 0.15)⁵
= 36000(0.85)⁵
= $15973.39125
Approximately = $15973.4
The value of the boat is $15,973 after 5 years.
Given that,
New boat cost is (A) $36,000.Depreciation rate is (r) 15%.We need to find the value of boat after (t) 5 years.According to the scenario, computation of the given data are as follows,
Value of boat = [tex]A (1 - r )^{t}[/tex]
By putting the value, we get
Value = [tex]36,000(1 - 0.15)^{5}[/tex]
= [tex]36,000(0.85)^{5}[/tex]
= 36,000 [tex]\times[/tex] 0.4437053125
= $15,973.4 or $15,973

A student babysits and charges a flat fee of $4.00 just for travel to the residence and then $6.00 per hour for the evening. a. Write an equation for the relationship between d, the amount of dollars the student can earn in an evening and h, the amount of hours the student babysits.
Answers
Answer:
d = 4 + 6h
Step-by-step explanation:
Given that :
Travel charge = $4 flat fee
Hourly charge = $6 per hour
Amount of dollar student can earn in an evening = d
Amount of hours spent babysitting = h
d = travel charge + (hourly charge * amount of hours)
d = $4 + ($6 * h)
d = 4 + 6h

How to convert 1 euro to php peso?
And can you explain. Advance Thank you
Answers
Answer with Explanation:
Euro is the currency of some countries in the European Union like Germany, France, Greece, Estonia, etc.
Php refers to Philippine peso. This is the currency used in the Philippines.
In order to convert Euro to Php, you have to check the value of 1 Euro in comparison to Php. The value is not stable and it fluctuates depending on the economic situation of the country.
The value of 1 Euro (€1) as of today is ₱57.03 (you can check this online or on the newspaper).
Let's say you want to convert €5 to ₱ . You can do this:
€5 x [tex]\frac{57.03 pesos}{1 Euro}[/tex] = ₱285.15 (therefore, 5 Euros is equivalent to ₱285.15)
Always remember to check the value of one currency to another currency in order to arrive at a correct equivalent.
