The product of the ages of Sally
and Joey now is 175 more than
the product of their ages 5 years
prior. If Sally is 20 years older
than Joey, what are their current
ages?
The product of the ages of
Current age of Sally is 25
Current age of Joey is 5
Let age of Sally 5 years prior be x
age of Joey 5 years prior be y
Now the age of Sally is x+5
Now the age of Joey is y+5
product of the ages of Sally and Joey now is 175 more than the product of their ages 5 years prior.
(x+5)(y+5)=175+xy
x y + 5x +5y +25 = 175 + x y
5x+5y = 175-25 = 150
x+ y = 30 .. .. ..1
Sally is 20 years older than Joey
x=20+y
Substitute x=20+y in .. . 1
20+y + y = 30
2y=10
y=5
x=20+y=20+5=25
Current age of Sally is 25
Current age of Joey is 5

A cargo truck is traveling 70 miles per hour and plans to travel 840 miles, plus or minus 105 miles, depending on fuel levels. Fnd the minimum and maximum number of hours the truck will travel at that speed.
The minimum is 10.5 hours and the maximum is not 12.2 hours.
The minimum and a maximum number of hours the truck will travel at that speed are 10.5 and 13.5 hours respectively.
What is velocity?Velocity is the rate of distance covered per time. Velocity could be average or instantaneous.
Average velocity = total distance / total time taken
Units of velocity are given by ⇒ meter/second
Speed of truck = 70 miles/hour
Maximum distance = 840 + 105 = 945 miles.
Minimum distance = 840 - 105 = 735 miles.
Now,
Time = distance / velocity
Minimum time = minimum distance / velocity
So,
Minimum time = 735 / 70 = 10.5 hour.
Maximum time = maximum distance / velocity.
Maximum time = 945 / 70 = 13.5 hour.
Hence "The minimum and a maximum number of hours the truck will travel at that speed are 10.5 and 13.5 hours respectively".

Compute the derivatives at the given value of a
1) The derivative of the function g(x) = (3x - 5)/(x - 2) at a = 1 is; g'(1) = -1
2) The derivative of the function f(x) = √(3x - 4) at a = 2 is; 3/(2√2)
What is the Derivative of the Function?1) We want to find the derivative of the function g(x).
g(x) = (3x - 5)/(x - 2)
g'(x) = -1/(x - 2)²
Thus;
g'(1) = -1/(1 - 2)²
g'(1) = -1
2) We want to find the derivative of the function f(x).
f(x) = √(3x - 4)
f'(x) = 3/(2√(3x - 4))
f'(2) = 3/(2√(3(2) - 4))

A bicyclist rides 14 miles in 112 minutes. If she continues at this speed, how long will it take her to travel 35 miles? Answer quick hurry
Answer:
280 minutes
Step-by-step explanation:
The new distance travelled is 2.5 times larger than the previous (35/14 = 2.5), therefore, the new time needed to be travelled would also be 2.5 times larger than the original time taken.
[tex]112 \times 2.5 = 280[/tex]
Answer:
it will take her 280 minutes to travel 35 miles
Step-by-step explanation:
miles per hour = miles / hours
or in this case, miles / minutes
[tex]\frac{14 miles}{112 minutes}[/tex]
divide both the top and bottom by 112
[tex]\frac{0.125 miles}{1 minute}[/tex]
= 0.125 miles per minute

A patient is to receive 0.25 mg of Medication A per kg of body weight per day. If the patient is a 157 lb man, how much medication A will he need?
The patient needs 17.66 mg of medication A .
Unitary method is "A way of finding a single-unit value from a multi-unit value, and then finding a multi-unit value from a single-unit value."For simplicity, always write what you calculate on the right and what you know on the left.In order to do that, we must first find the value of one thing by division and then find the value of more or fewer things by multiplication.It is given that a patient has weight 157 lbs.
We apply division because we need to find the cost of one item given the cost of many items. If you need to find the cost of many items from the cost of one item, apply the multiplication operation.
We need to convert this weight in kilogram using unitary method , we get 1 pound have = 0.45 kilogram
157 pound will have [tex]=157\times0.45[/tex]
[tex]=70.65[/tex] kilogram
A patient receive 0.25 mg of Medication A per kg
Using unitary method , we get

A sequence is defined recursively using the formula f(n+1)=-0.5f(n). If the first term of the sequence is 120, what is f(5)
Answer:
The sequence's fifth term is equal to 7.5.
Step-by-step explanation:
It is given in the question that A sequence is defined recursively using the formula f(n+1)=-0.5f(n) and we need to calculate f(5) if the first term of the sequence is 120.
Firstly,
The definition of a series is given by the formula f (n + 1) = -0.5 f. (n).
Now, what will be f(5) if the sequence's initial term is 120, let's calculate;
Recursively, a series is defined as follows;
=> f(n) = 120 if n = 1, otherwise.
Otherwise,
=> f(n) =-0.5f(n-1) if n > 1.
Now,
=> f(1) = 120
=> f(2) = -0.5f(1) = -0.5(120) = -60
=> f(3) = -0.5f(2) = -0.5(-60) = 30
=> f(4) = -0.5f(3) = -0.5(30) = -15
=> f(5) = -0.5f(4) = -0.5(-15) = 7.5
So, For n > 1, f(n) = (-0.5)(n-1) × 120
Therefore, the sequence's fifth term is equal to 7.5.
