What type of conic section is represented by the parametric equations below? X=3cos(t)-1 y=3sin(t)+4
Answer:
Circle
Step-by-step explanation:
Examples of conic sections are the circle, the ellipse, the parabola and the hyperbola. Parametric equations are used to express the x and y variables in terms of a less complicated manner using a third variable (t or θ).
The parametric equation for a circle with an equation [tex](x-h)^2+(y-k)^2=r^2[/tex] is given by:
[tex]x=rcos(t)+h, y=rsin(t)+k[/tex]
where r is the radius of the circle and (h, k) is the center of the circle.
A conic section with a parametric equations X=3cos(t)-1, y=3sin(t)+4 is a circle with center at (-1, 4) and radius of 3. The equation of the circle is:
(x + 1)² + (y - 4)² = 3²
The water tank in your school holds 20 liters of water. One day it was 34 full. That day, 14 liters of tank capacity was used up. How many liters of water remained in the tank at the end of the day
Answer:
20
Step-by-step explanation:
The water tank in the school hold 20 liters of water
One day it was 34 liters full
14 liters of water was used up
Therefore the quantity of water left can be calculated as follows
= 34-14
= 20
Hence 20 liters of water remains in the tank

Determine whether the relationship is a function or not. Explain why or why not!
Answer:
Yes or No: Yes
Explanation: It is a function because each input is paired with only one output, as shown in the table.
Step-by-step explanation:
Without graphing, determine whether the system of linear equations has one solution, infinitely many solutions, or no solution. Explain your reasoning.

[tex]y = 15x + 2[/tex][tex]y - 15x - 2 = 0[/tex]Now, the equations are in the form of
[tex]a_1x {}^{2} + b_1x + c_1 = 0[/tex][tex]a_2x {}^{2} + b_2x + c_2 = 0[/tex]where,
[tex] \dfrac{a_1}{a_2} = \dfrac{b_1}{b_2} \neq \dfrac{c_1}{c_2} [/tex]
therefore the equations would have no solution .

The lateral area of a cylinder is 1872 square cm.The height is 6 cm.What is the radius.
Answer:
9.97 i think
Step-by-step explanation:
Answer:
r = 24.41cm
Step-by-step explanation:
If you're only trying to find the radius, use the equation:
[tex]Area = \pi r^2[/tex]
When rearranged to make r the subject:
[tex]r = \sqrt\frac{Area}{\pi }[/tex]
When the variables are added:
[tex]r = \sqrt\frac{1872}{\pi }[/tex]
[tex]r = 24.41[/tex]

Find the next 3 terms of the following sequence 10,17,24
Answer:
31,38,45
Step-by-step explanation:
Answer:
31, 38, & 45
Step-by-step explanation:
The sequence 10, 17, 24 increases by 7 each term.
10 + 7 = 17
17 + 7 = 24
24 + 7 = 31
31 + 7 = 38
38 + 7 = 45
HELPPPPPP PLEASE Jerrod's mountain bike has a tire diameter of 26 inches, How far will the
bike travel in 100 rotations of its tires?
Answer:
Step-by-step explanation:
The process here is to find out how far the tire travels in one rotation, then multiply that by 100. That means we need to find the circumference of the tire since the circumference tells us how far around the outside of the tire it is in inches.
C = πd where d is the diameter of the tire.
C = 3.1415(26) so
C = 81.679 inches. Multiply that by 100 to get
8167.9 inches, which in miles is a little over 1.5 miles

Given the sequence 70, 49, 34.3, 24.01, ....
a. What is the common multiplier?
b. What is the zeroth term?
c. What is the value of the 25th term t(25)?
Answer: See explanation
Step-by-step explanation:
a. What is the common multiplier?
This will be gotten by dividing the second term by the first term. This will be:
= 49/70 = 0.7
Common multiplier = 7/10 or 0.7
b. What is the zeroth term?.
a = 70
The zeroth term is 70
c. What is the value of the 25th term t(25)?
nth term = ar^n-1
25th term = ar^25-1
= ar^24
= 70 × 0.7^24
= 70 × 0.0001916
= 0.013412

a. 13
b. -7
c. -10.4
d. 3.25
Answer:
x = 13
Step-by-step explanation:
0.6(x + 2) = x - 4
0.6x + 1.2 = x - 4
x - 0.6x = 1.2 + 4
0.4x = 5.2
x = 52/4

a small chocolate sundae costs $3. each topping you add costs $0.50. how much would it cost to get a small sundae with P toppings added?
Answer:
3=0.5p
Step-by-step explanation:
The cost to get a small sundae with P toppings added represented as 3 + 0.5p.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Let's consider the toppings added to the chocolate sundae represented by p.
We will use the unitary method,
The cost of topping added to one chocolate = $0.50
The cost of topping added to p chocolate = $0.5p
So, the cost to get a small sundae with P toppings added is;
3 + 0.5p
Therefore, the cost to get a small sundae with P toppings added represented as 3 + 0.5p

A rectangle has a length of 14 yards less than 9 times its width. If the area of the rectangle is 6183 square yards, find the length of the rectangle.
Answer:
[tex]l=238\ yards[/tex]
Step-by-step explanation:
From the question we are told that:
Area of Rectangle A=6183
Equation of Length
[tex]l=9w-14[/tex]
Where
[tex]w=width\ of\ triangle[/tex]
Generally the equation for Area of Rectangle is mathematically given by
[tex]A=(9w-14)w[/tex]
[tex]A=9w^2-14w[/tex]
[tex]6183=9w^2-14w[/tex]
[tex]9w^2-14w-6183=0[/tex]
[tex]w=28[/tex]
Therefore
[tex]l=9(28)-14[/tex]
[tex]l=238\ yards[/tex]
please help I'll be your best friend
Answer: Check out the diagram below
[tex]1.5 \le x \le 5.5[/tex]
The lengths can be between 4 and 12 units
=======================================================
Explanation:
Let's find an expression that represents the area.
The length is 2x+1 and the width is 3. Multiply those two and we get
3(2x+1) = 6x+3
The area is 6x+3 square units.
In other words, A = 6x+3 represents the area.
------------------
We're then told that [tex]12 \le A \le 36[/tex] saying that the area is between 12 and 36 square units (including both endpoints).
We'll replace the A with 6x+3 and solve for x like so:
[tex]12 \le A \le 36\\\\12 \le 6x+3 \le 36\\\\12-3 \le 6x+3-3 \le 36-3 \ \text{ .... see note1}\\\\9 \le 6x \le 33\\\\\frac{9}{6} \le \frac{6x}{6} \le \frac{33}{6} \ \text{ .... see note2}\\\\\frac{3}{2} \le x \le \frac{11}{2}\\\\1.5 \le x \le 5.5\\\\[/tex]
note1: I subtracted 3 from all sides to undo the "plus 3"
note2: I divided all sides by 6 to undo the multiplication
------------------
We just found that [tex]1.5 \le x \le 5.5\\\\[/tex] so it says that x is between 1.5 and 5.5 including both endpoints.
Plug in the smallest possible x value to find the smallest possible length
length = 2x+1
L = 2(1.5)+1
L = 3+1
L = 4
The smallest possible length is 4 units. Multiply this with the height 3 and we get L*W = 4*3 = 12 which is the smallest possible area.
------------------
Now use x = 5.5 to find the largest value of L possible
L = 2x+1
L = 2(5.5)+1
L = 11+1
L = 12
Then note how L*W = 12*3 = 36 is the max area possible, which matches with that your teacher wrote. So this confirms we have the correct value.
If you're not sure which values go where, check out the diagram below.
What is the equation of a circle with a center located at (4, -1) and a radius of 9?
Answer:
(x-4)^2 + (y+1)^2 = 81
Step-by-step explanation:
you clearly have internet access and could have very quickly searched for the equation of a circle.
(x-h)^2 + (y-k)^2 = r^2
with (h,k) being the center.
=> (x-4)^2 + (y+1)^2 = 81

why is probability limited to numbers between 0 and 1
Answer:
Probability by definition is the extent to which an event is likely to occur, measured by the ratio of the favourable cases to the whole number of cases possible.
Since number of elements in the set of favourable cases is less than or equal to the number of elements in the set of whole number of cases, their ratio would always end up being 1 or less than one.
Probability equals one when favourable number of cases are same as that of the whole number of cases and probability equals zero when there is no favourable case
