Answer:
True
Step-by-step explanation:
4 times 1 fourth is just one
7+1 =8
8=8
therefore this statement is true

Answer:
Step-by-step explanation:
Ah...right triangle trig. Gotta love this stuff (you better, because it never goes away!). We need to remember SohCahToa which tells us that the sin of an angle is equal to the side opposite the angle over the hypotenuse; the cos of an angle is equal to the side adjacent to the angle over the hypotenuse; the tan of an angle is equal to the side opposite the angle over the side adjacent the angle. x is the side across from our given angle, while 7 is the side adjacent. That means that we will use the tangent ratio to solve.
and filling in:
. Solving for x:
7tan(48) = x. Do this on your calculator in DEGREE mode (NOT radians!) to get that x = 7.77 which rounds nicely to D: 7.8
We have been given that 4 is a zero of the polynomial function . We are asked to find the remaining zeros of function.
Since 4 is a zero of f(x), so will be a factor of f(x).
Let us divide our function f(x) by .
Now we will cancel out from numerator and denominator.
Now we will use quadratic formula to solve for x as:
Now we will use .
Therefore, other two zeros of function are .
