Derivative of sin(x+y)
Answer:
[tex] \frac{dy}{dx} = \frac{ \cos(x + y)}{[1 - \cos(x + y)] } [/tex]
Step-by-step explanation:
Let y = sin(x+y)
Differentiating with respect to x on both sides.
[tex] \frac{dy}{dx} = \frac{d}{dx} \sin(x + y) \\ \\ \frac{dy}{dx} = \cos(x + y)\frac{d}{dx} (x + y) \\ \\ \frac{dy}{dx} = \cos(x + y)(1 + \frac{dy}{dx}) \\ \\ \frac{dy}{dx} = \cos(x + y) +\cos(x + y) \frac{dy}{dx} \\ \\ \frac{dy}{dx} - \cos(x + y) \frac{dy}{dx} = \cos(x + y) \\ \\ \frac{dy}{dx} [1 - \cos(x + y)] = \cos(x + y) \\ \\ \purple {\bold {\frac{dy}{dx} = \frac{ \cos(x + y)}{[1 - \cos(x + y)] }}} [/tex]

A rectangular swimming pool is 8 ft deep. One side of the pool is 3.5 times longer than the other. The amount of water needed to fill the swimming pool is 5488 cubic
feet. Find the dimensions of the pool.
Answer:
Dimension of pools are length = 42 ft , width = 12 ft and depth = 8 ft that is 42ft × 12ft × 8 ft
Step-by-step explanation:
given that depth of pool = 8 ft
let say one side of pool that is width = x
so other side of pool that is lenght = 3.5x [ given ]
volume of rectangular swimming pool is same as amount of water required to fill the swimming pool = 4032 cubit ft
Volume of rectangular pool = length × width × depth of swimming pool
⇒ 4032 cubic ft = 3.5x × x × 8
⇒ 4032/(3.5 ×8 ) = x²
⇒x² = 144
⇒x = √144 = 12
⇒3.5x = 12 × 3.5 = 42
hence dimension of pools are length = 42 ft , width = 12 ft and depth = 8 ft that is 42ft × 12ft × 8 ft

Find the surface area of the following figure.
Answer:
[tex]\boxed{\textsf{\pink{ Hence the TSA of the cuboid is $\sf 32x^2$}}}.[/tex]
Step-by-step explanation:
A 3D figure is given to us and we need to find the Total Surface area of the 3D figure . So ,
From the cuboid we can see that there are 5 squares in one row on the front face . And there are two rows. So the number of squares on the front face will be 5*2 = 10 .
We know the area of square as ,
[tex]\qquad\boxed{\sf Area_{(square)}= side^2}[/tex]
Hence the area of 10 squares will be 10x² , where x is the side length of each square. Similarly there are 10 squares at the back . Hence their area will be 10x² .
Also there are in total 12 squares sideways 6 on each sides . So their surface area will be 12x² . Hence the total surface area in terms of side of square will be ,
[tex]\sf\implies TSA_{(cuboid)}= 10x^2+10x^2+12x^2\\\\\sf\implies\boxed{\sf TSA_{(cuboid)}= 32x^2}[/tex]
Now let's find out the TSA in terms of side . So here the lenght of the cuboid is equal to the sum of one of the sides of 5 squares .
[tex]\sf\implies 5x = l \\\\\sf\implies x = \dfrac{l}{5} \\\\\qquad\qquad\underline\red{ \sf Similarly \ breadth }\\\\\sf\implies b = 3x \\\\\sf\implies x = \dfrac{ b}{3}[/tex]
[tex]\rule{200}2[/tex]
Hence the TSA of cuboid in terms of lenght and breadth is :-
[tex]\sf\implies TSA_{(cuboid)}= 10x^2+10x^2+12x^2\\\\\sf\implies TSA_{(cuboid)}= 20\bigg(\dfrac{l}{5}\bigg)^2+12\bigg(\dfrac{b}{3}\bigg) \\\\\sf\implies TSA_{(cuboid)}= 20\times\dfrac{l^2}{25}+12\times \dfrac{b^2}{9}\\\\\sf\implies \boxed{\red{\sf TSA_{(cuboid)}= \dfrac{4}{5}l^2 +\dfrac{4}{3}b^2 }}[/tex]
A solid gold ingot has a volume of 200 cm3 and a mass of 3.9 kg.
What is the density of gold?
Step-by-step explanation:
convert 3.9 kg to grams
3.9×1000=3900 g
density = mass/ volume
= 3900/ 200
=19.5 g/cm3

If you see The abc triangle you can see that triangle DEF is about twice the size of the other triangle so if you would double the size of the small triangle by the same number which was 20 you would do 20 + 20 = 40 and you would multiply 4 x 5 which equals 20 and add 20 + 20 which equals 40 which is the double amount of triangle ABC

an extra comment so the other guy gets brainlist:)
Step-by-step explanation:
Select the functions that are equivalent to P(t) = 76529( 1.21), where t is time in
years.
P(t) = 76529(1.049)4t
P(t) = 76529(1.032) 6t
P(t) = 76529(1.00834) 2t
P(t) = 76529(102.1)
21
P(t) = 76529 1.212
P(t) = 76529(1.016)121
P(t)=75529(1.21 1/2)2t
P(t)=76529(1.016)12t

Answer:
i dont know the exact answer but i can give you the instuctions on how to do do it.
Step-by-step explanation:
1. Cut 4420 in half (4420 divided by 2). Store that for later. This is two hours.
2. Multiply 4420 by 2 (This will give you 8 hours which, in mathematics, when added with two is ten.)
3. Add the answers you got from 1 and 2 to get your answer.
And there you have it.

The measure of one angle of a right triangle is 42∘ more than the measure of the smallest angle. Find the measures of all three angles.
Answer:
Step-by-step explanation:
A ≤ B ≤ C
C = 90°
B = A+42°
A+B = 90°
A+(A+42) = 90°
A = 24°
B = A+42° = 66°
24, 66, 90 are the measure of all three angles of the right angle triangle
What is right-angle triangle?A triangle is said to be right-angled if one of its angles is exactly 90 degrees. The total of the other two angles is 90 degrees. Perpendicular and the triangle's base are the sides that make up the right angle. The longest of the three sides, the third side is known as the hypotenuse.
Given, The measure of one angle of a right triangle is 42∘ more than the measure of the smallest angle.
Let "x" be the smallest angle in a right angle triangle.
So, biggest angle in the triangle will be x +42
Since, sum of the all the angles in a triangle = 180
x + x+ 42 +90 = 180
2x + 42 = 90
2x = 48
x = 24
Measure of the smallest triangle =x = 24
Measure of the biggest angle = 24 + 42
Measure of the biggest angle = 66
therefore, The measure of all three angles of the right angle triangle are 24, 66, 90.
