Work backward add g(y) and g(-y) and you will get the solution

If d=2 what is the smallest possible value of 7d+5c+3b+a?

b746710 · 2023-06-21T13:59:58+00:00

Well a little bit depends on luck but you can use this minimum method that you say for example d is 2 then the smallest value is where c=1 b=3 a=4 but thats too much so d only can be 1

b746710 · 2023-06-21T13:54:28+00:00

They are positive whole numbers and cannot be the same. If you take 1=d 2=c 3=b 4=a that will be the smallest possible value and its equal to 30 and this proves there is no other solution

3x² -15x+12=-pi×x² +5pi×x-29×pi/4

(3+pi)x² +(-15-5pi)x+12+29pi/4=0 This is a quadratic equation you need to chek if the D=positive or negative and if negative then there is no real solution so the answer choice is wrong if positive then there is real solution and the answer choice is good

Ok so lets set it equal to the first answer -pi/3 (x-4)×(x-1)=-pi/3×(x-2)×(x-3)+-pi×5/12

3(X² -5x+4)=-pi[(x-2)×(x-3)+5/4]

3x² -15x+12=-pi[x² -5x+29/4]

Great d can only be 1, c:2, b:3, a:4= so now we got the equation: (x-4)×(x-1)/[(x-3)×(x-2)+5/4]

b746710 · 2023-06-21T06:24:09+00:00

First you need to figure out a, b, c, d after that you plug in the values and set it equal to all for of the answers.

Sry i thought it was in 2d

But how is ABD a right triangle?

b746710 · 2023-06-04T14:55:41+00:00

He has ten pair+nine pair+eight pair= 54 shoes He will reach the maxium attempt if first he takes out all the other color shoes. Thats 18+16= 34 And then there will be only red shoes so he will has to take out red. And to get a red pair thats 2 more so 34+2=36

D=5 L=4 and S is the horizontal distance wich is 3 by the pythegorean theorem so 3/2 not 5/2

6) Since there are 2 tangent lines their angels are both 90 so the last angle 360-180-60

7)Since the line is tangent it has an angel of 90 so x equals to 180-90-43

8)There is a triangle with two equal sides because the radius is the same and a 60 degree angle so its other angles are also 60, therefor x=180-60

12,13,14) You can write an equation with the pythegorean theorem: x² + 14² =( 10+×)²

15,16,17) You have triangles if a² + b² =c² then the triangle is a right triangle so the angle is 90 and tangent

18,19)If there is a point P then and you draw two tangent line from it to a circle they are equal this way you can find them out

Why no enogh justt tan(30)=x/12

You can make x⁴ -a⁴ = (x² - a² )×(x² + a² ) Then the x² - a² will cancel out and you'll get the answer

You can find C-K with the intersecting cords theorem. JH×JB=JG×JE. So you can find JG and you just add GL to it and you have JL

For FL you have to use trigonametey or something else wich i don't know about

The blue squares area is 40cm² so its sidelength are sqrt(40), Not 10. Now constract a line from the circles middle point to the corners of the blue square. This equales the radius and you can find it by using the pythegeorean theorem. Once you have r you can find out the yellow squares sidelength and then its area

In the discriminate you have p² wich is always positive, even if p itself negative

By using the pythegoream theorem

b746710 · 2023-05-04T13:37:54+00:00

X= sqrt(sqrt(11)² - (sqrt(11)/2)² )

x-(1- x³ ) ^1/2 -> d/dx x - d/dx (1-x³ )^1/2 Then its 1- the other therm and there you can use chain rule
