I believe the answer to your question is 11. Once you add the squares that aren't cut from the lines, you get 6.You then ad the bottom squares and you get 7, and then you keep adding the squares on the outside. Eventually you get 11 cubic squares.

Which equation can be used to prove 1 + tan2(x) = sec2(x)?

notsponge [240]

Answer:

fourth option

Step-by-step explanation:

Using the trigonometric identity

cos²x + sin²x = 1

Divide all terms by cos²x

$\frac{cos^2x}{cos^2x}$ + $\frac{sin^2x}{cos^2x}$ = $\frac{1}{cos^2x}$ which gives

1 + tan²x = sec²x

95i is a root of f(x)=x^2 +9025. find the other roots of f(x)

Alex_Xolod [135]

Answer:

Other root is -95i

Step-by-step explanation:

Here, Nature of roots of f(x) is imaginary roots.

Therefore, Roots are conjugate of each other.

Conjugate of x + yi is x - yi.

we get conjugate of 95i as -95i

Verification shows....

(x-95)(x+95i)=0

${x }^{2} - {95}^{2} {i}^{2} = 0 \\ {x }^{2} + {95}^{2} = 0 \\ {x }^{2} + 9025= 0 \\ f(x) = 0$

this, roots are -95i and 95i
