An object moves around x + y = 25 (which represents a
circle whose radius is 5 meters) at a constant speed. At time
t = 0 seconds, the object is at (5,0). When t = 1, it is at (4,3). Where is the object when t = 2? When t = 3? when t = n?
What is the object’s speed? At what times does the object return to (5, 0)? To arrive at your answers, what assumptions did you make?
Answer:
Step-by-step explanation:
There is an error in the question.
x + y = 25 is NOT the equation of a circle.
It should be x^2 + y^2 = 5^2.
Parametric equations for the circle:
x = 5cosθ
y = 5sinθ
After 1 second, the object is at (4,3), so θ=arctan(3/4).
At 2 seconds, θ=2arctan(3/4). The object is at (5cosθ,5sinθ) = (1.4, 4.8).
At 3 seconds, θ=3arctan(3/4). The object is at (-1.76, 4.68).
360°/arctan(3/4) ≈ 9.764
The object returns to (5,0) after 9.764 seconds.
Jennie is 5 years younger than Sammie. Five years ago, Sammie was four times older that Jennie. How old are they now?
Answer:
Jennie is 6 2/3
Sammie is 11 2/3
Step-by-step explanation:
Let s represent Sammie's age now. Then Jennie's age now is s-5. Their ages 5 years ago had the relation ...
(s) -5 = 4((s-5) -5)
s -5 = 4s -40
35 = 3s . . . . . . . add 40-s to both sides
35/3 = s = 11 2/3 . . . . divide by 3
si -5 = 11 2/3 -5 = 6 2/3
Sammie is 11 2/3, and Jennie is 6 2/3 now.
_____
Check:
Five years ago, their ages were 6 2/3 and 1 2/3 = 20/3 and 5/3. Sammie was 20/5 = 4 times as old as Jennie then, as required.
_____
Alternate solution
The difference in ages remains constant, so it was the same 5 years ago. Sammie was 4 times Jennie's age at that time, so the difference in their ages was 3 times Jennie's age. That is, 5 years was 3 times Jennie's age at that time, so Jennie was 5/3. At present, Jennie is 5/3 +5 = 20/3 = 6 2/3, and Sammie is 5 years older, so 11 2/3.
find the value of the variables. x and y
Answer:
x = 29.4
y = 17
Step-by-step explanation:
sin 90° / 34 = sin 60° / x
x = 34·sin 60°
x = 29.4
sin 90° / 34 = sin 30° / y
y = 34·sin 30°
y = 17

. Which of the following is a zero of the polynomial f(x)= x5+2x4+x+2?
A. I
B.-1
C.-2
D. 2
Answer:
x = -2 is a function
Step-by-step explanation:
To get which is a zero, we have to look at one value of x which when substituted into the polynomial will give -1
we have this as:
Let us try the value x = -2
-2^5 + 2(-2)^4 - 2 + 2
= -32 + 32 - 2 + 2 = 0
This means that the term x = -2 is a root of the equation

A tree grows 2 inches per year. It was 14 inches tall when it was planted. what would be this function discrete continuous or neither? whould it be a linear an exponential or neither? what would be the domain?
please help greatly appreciated
Answer:
This function is a continuous linear function that's domain is all positive real numbers.
Step-by-step explanation:
This function is continuous because every linear function is continuous and this function is the linear function y = 2x+14 where x is the years it has been planted and y is the height.
It is a linear function, it's hard to explain, but it has a dependent variable, the height of the tree that changes at a constant rate with the independent variable which is time in years.
The domain is all positive real numbers since time/years can not be negative.

Substitute the coordinate values in.
[tex]m = \frac{11 - 3}{2 - 0} \\ m = \frac{8}{ - 2} \longrightarrow \frac{4}{ - 1} \\ m = - 4[/tex]

Answer:
z is 95 degrees.
Step-by-step explanation:
Linear angle pairs make 180 degrees. Since ∠ABC is a straight line, it is 180 degrees. And since ∠ABD and ∠DBC are on that line, they are a linear angle pair. You just need to find out what number + 85 degrees would = 180 degrees, which in this case, is 95.
Also in the first question P = 30, because 2(30) + 30 = 90
please help!
Remember what we know about vertical angles and solve for x.

a ladder is leaning against a building. the top of the ladder is 21 feet up the wall. the bottom of the ladder is 20 feet away from the base of the building. how long is the ladder
Answer:
29
Step-by-step explanation:
We can use the pythagorean theorem to find the length of the ladder
[tex] {20}^{2} + {21}^{2} = c {}^{2} [/tex]
[tex]400 + 441 = {c}^{2} [/tex]
[tex]841 = {c}^{2} [/tex]

he following section is a statement from the rental agreement Tim signed when he rented his car this past weekend.
"Upon checkout, the fuel level of the vehicle will be determined by turning the vehicle on and visually inspecting the fuel gauge. The approximate fuel level will be recorded on the Check-Out sheet and verified with initials by the vehicle Renter. One copy of the Check-Out sheet will be given to the customer. Another copy will be kept with the on-site records of the vehicle.
"The rented vehicle must be returned with a minimum fuel level the same as that indicated on the Check-Out sheet. A vehicle returned with a fuel level less than the approximate level indicated on the Check-Out sheet will be completely refueled with on-site pumps. The price of the fuel used to refuel the vehicle will be added to the Renter's total charge at a cost of $4.50 per gallon plus a $5.00 refueling charge."
Tim is running extremely late and has just 5 minutes to return his rental car to the agency. The fuel tank in the car is half empty. It was full when he picked it up. (The car has a 12-gallon fuel tank.) He doesn't think he can get gas and get to the agency to return the car in time. Returning the car a day late will result in an extra daily rental charge of $32.00 and refueling the car on his own will cost $2.59 per gallon at the local gas station. Which of the following statements is true?
a.
It would be cheaper to refuel the car and return it a day late.
b.
It would be cheaper to return the car on time and pay the refueling costs.
c.
It would cost about the same to return the car on time without gas or one day late with gas.
d.
Tim is not responsible for refueling the car when he returns it.
Answer:
B
Step-by-step explanation:
Although this problem is quite long and exhausting, it is deceptively simple.
We know that his 12-gallon fuel tank is only half full, so we know that the car needs 6 more gallons of fuel.
If he turns in the car late, he will have to pay y = 2.59x + 32.00, where x is the number of empty gallons (in this case, 6)
In this case, he will pay 2.59(6) + 32.00 = $47.54
If he turns in the car on time, he will have to pay y = 4.50x + 5.00, where x is the number of empty gallons (still 6).
In this case, he will pay 4.50(6) + 5.00 = $32.00
Using these results, we know that B must be true.
