Answer:
Y² = (1-X) / 2
Step-by-step explanation:
According To The Question, We Have
X= Cos2t & Y= Sint
the cartesian equation of the curve is given by Y² = (1-X) / 2 .
Proof, Put The Value of X & Y in Cartesian Equation, We get
Sin²t = {1-(1-2×Sin²t)} / 2 [∴ Cos2t = 1 - 2×Sin²t]
Taking R.H.S
(1-1+2×Sin²t)/22Sin²t/2 ⇔ Sin²t = L.H.S (Hence Proved)Find the surface area of the figure using its net

Step-by-step explanation:
What is the value of the 30th percentile for the data set? 6283 5700 6381 6274 5700 5896 5972 6075 5993 5581 5972 6274 6075 5896
5896
Step-by-step explanation:Given data set:
6283 5700 6381 6274 5700 5896 5972 6075 5993 5581 5972 6274 6075 5896
To calculate the 30th percentile;
i. Rearrange the given data set in ascending order.
5581 5700 5700 5896 5896 5972 5972 5993 6075 6075 6274 6274 6283 6381
ii. Use the following formula to get the index of the value at the 30th percentile.
N = p(n)
Where;
N = the number of data points at or below the intended percentile.
p = the intended percentile.
n = the number of points in the data.
In this case;
p = 30 percent = 0.3
n = 14
Substitute these values into the equation;
N = 0.3(14)
N = 4.2
iii. From the calculated index, find the value of the 30th percentile.
If the index is a whole number x, the desired percentile is the average of the values at index x and x+1.
For example if the index is 4, then the desired percentile is the average of the values at index 4 and 5. In our case, that will be;
[tex]\frac{5896+5896}{2}[/tex] = 5896
If the index is a decimal number, it is rounded up to the nearest integer. The value at the rounded index is the desired percentile.
For example, in our case, the index is 4.2 which when rounded up becomes 4.
Therefore, the data point or value at index 4 is the 30th percentile. From the arrangement in (ii) above, that will be 5896. i.e
5581 5700 5700 5896 5896 5972 5972 5993 6075 6075 6274 6274 6283 6381

Three same-sized cubes are attached to the top of a rectangular prism as shown below.
If a=10 cm, b = 26 cm, and c = 6 cm, what is the surface area of the figure?
ANSWER ASAP PLEASE!!! IT WOULD MEAN ALOT
Answer:
Surface area of the figure = 1672 [tex]cm^{2}[/tex]
Step-by-step explanation:
Surface area of the figure = surface area of the prism + surface area of the 3 cubes
The surface area of the rectangular prism = sum of the area of its individual sides
= 2(26 x 10) + 2(10 x 10) + 2(26 x 10)
= 520 + 200 + 520
The surface area of the rectangular prism = 1240 [tex]cm^{2}[/tex]
Surface area of one of the cubes = 5(6 x 6)
= 180 [tex]cm^{2}[/tex]
The surface area of the 3 cubes = 3 x 180
= 540 [tex]cm^{2}[/tex]
Thus, the surfaces of the cubes on the prism covers a total area of 108 [tex]cm^{2}[/tex].
So that;
The surface area of the figure = (1240 - 108) + 540
= 1132 + 540
= 1672 [tex]cm^{2}[/tex]

A rod 123.75 cm long is sawn into 16 equal lengths. If a wastage takes place of ¼ cm for each saw cut, what is the length of each piece?
Answer:
7.5 cm
Step-by-step explanation:
A rod 123.75 cm long is sawn into 16 equal lengths.
The length of each rod is calculated as:
123.75cm/16 =
= 7.734375cm
If a wastage takes place of ¼ cm for each saw cut,
The length of each piece is calculated as:
7.734375cm - 1/4 cm
7.734375cm − 0.25 cm
7.484375cm
Approximately = 7.5 cm
Therefore, the length of each piece = 7.5 cm

Jameson middle school give bottles of water to teachers and students who are going on a field trio. The school orders 500 bottles of water. They plan to give 35 bottles of water to teacher . They orderd at least 2 bottles of water for each student. How many students could be going on the field trip? Show your work
Answer: Almost 232 students going on the field trip.
Step-by-step explanation:
Let x be the number of students going on the field trip.
As per given,
[tex]2x+35 \leq500[/tex], where [tex]x\geq2[/tex].
To solve the inequality , subtract 35 from both sides
[tex]2x\leq465\\\\x\leq232.5[/tex] [divide both sides by 2]
i.e Almost 232 students going on the field trip.

3 connecting lines are shown. Line D F is horizontal. Line D E is about half the length of line D F. Line F E is about one-third of the length of line D F.
Which inequality explains why these three segments cannot be used to construct a triangle?
EF + FD > DE
ED + EF < DF
ED + EF > DF
EF + FD < DE
Answer:
second option ED + EF < DF
Step-by-step explanation:
in order to build a triangle or of 3 lines, every pair of 2 of these lines must be longer together than the third line.
otherwise you could put them together and place them flat alongside the third line and still cannot connect to the endpoint of the third line => no triangle possible.
ED (or DE) is half of the third line (DF or FD).
FE (or EF) is a third of the third line.
1/2 + 1/3 < 1/1 (because 1/3 < 1/2)
Answer:
ED + EF < DF or b

if h(x)=x-7 and g(x)= x^2, which expression is equivalent to (goh)(5)
Answer:
(goh)(5) = 4
Step-by-step explanation:
(goh)(x) = g(x-7)
g(x-7) = (x-7)^2
g(x-7)= x^2 - 14x + 49
(goh) = x^2 - 14x + 49
(goh)(5) = 5^2 - 14(5) + 49
(goh)(5) = 25 - 70 + 49
(goh)(5) = 4
