100- 10 is 90 if that’s the question
So 90 or ninety
If you mean place value it’s tenths

X=? Y=6 75 degree angle at (0,0) What is X?

choli [55]

Answer:

$X=12-6\sqrt{3}=1.6077$

Step-by-step explanation:

Given that $Y=6$

$\tan(75)=\frac{Y}{X} \\X=\frac{Y}{\tan(75)}=Y\cot75=6\cot75 \\\\Calculate \ \cot(75)\\\tan(75)=\tan(45+30)=\frac{\tan45+\tan30}{1-\tan45 \cdot \tan30} =\frac{1+\frac{1}{\sqrt{3} } }{1-\frac{1}{\sqrt{3} } } \\\tan75=\frac{\sqrt{3}+1 }{\sqrt{3}-1 } =2+\sqrt{3} \\\cot75=\frac{1}{2+\sqrt{3} } =\frac{2-\sqrt{3} }{2^2-3} =2-\sqrt{3} \\\\Hence\\X=6\cot75=6 \cdot(2-\sqrt{3})\\X=12-6\sqrt{3} \approx1.6077$

Part 1:

Given that a store had 235 MP3 players in the month of January and that every month, 30% of the MP3 players were sold and 50 new MP3 players were stocked in the store.

The number of MP3 players in the store after the previous months sale is given by 0.7f(n - 1) and the number of MP3 players in the store after new MP3 were added is 0.7f(n - 1) + 50.

Therefore, the recursive function that best represents the number of MP3 players in the store f(n) after n months is given by f(n) = 0.7 x f(n − 1) + 50, f(0) = 235, n > 0

Part 2:

The average rate of change of a function from a to b is given by

$average \ rate \ of \ change= \frac{f(b)-f(a)}{b-a}$

Given that the equation showing the value of her investment after x years is given by

$f(x)=500(1.05)^x$

Thus, the average rate of change of the value of Sophia's investment from the second year to the fourth year is given by

$Average \ rate \ of \ change= \frac{f(4)-f(2)}{4-2} \\ \\ = \frac{500(1.05)^4-500(1.05)^2}{2} = \frac{607.75-551.25}{2} \\ \\ = \frac{56.5}{2} =28.25$

Therefore, the average rate of change of the value of Sophia's investment from the second year to the fourth year is 28.25 dollars per year.

Use the net to find the surface area of the prism

arsen [322]

Answer

364 i think

Step-by-step explanation:

find the area of triangles + area of rectangles

area of triangles: b x h x 1/2

6 x 4 x 1/2

= 12

but two triangles, so . double it and then you get 24 for the two triangles areA

area of rectangles;

l x w

22 x 6

= 132

but two up and down rectangles, so double it = 264

now back rectangle:

l x w

22 x 4

= 88

Add it all up together and you have the surface area!

Surface Area - The area of the surface of the 3D object, NOT volume

pls mark brainliest unless someone else answered it or im wrong thank you! :D
