60 since this times that equal that’s
Answer:
16
Step-by-step explanation:
1+4+6+5
First: Equations are solved. is an expression, and expressions can be simplified.
Now suppose . Imagine a right triangle with one angle (not the one opposite the hypotenuse, of course) labeled . This relation suggests that
and under the hood, we're assuming that , because otherwise we wouldn't be able to properly alternate from to so seamlessly.
Now,
so the given expression is the same as the tangent of that same angle .
If , then in the triangle, the leg opposite the angle occurs with the length of the hypotenuse in a ratio of to 2. By the Pythagorean theorem, the remaining side - call it - satisifies
and we have
The given expression becomes undefined when y=5 or y = -3. The answer is option D.
Step-by-step explanation:
The value of the given expression becomes undefined when the denominator equals 0.
Hence to find the value of y which makes the expression undefined, we can equate the value of the denominator to zero and solve it .
Step 1
Equate the denominator to 0.
y^{2} - 2y -15 = 0
Step 2
Solve the above equation to get the value of y.
y^{2} - 2y -15 = 0
=> (y-5)(y+3) =0 [ Roots of the quadratic equation]
=> y = 5 or y = -3.
Hence when y = 5 or y = -3 the denominator becomes 0, which makes the expression (2y+7)/0 and hence it is undefined.
Answer:
It would be 12 as well
