Answer:
The height is 6 feet, and the length of the ramp is the hypotenuse of a right triangle with angle 28 degrees with the ground
Step-by-step explanation:sin
28=6/x
x*sin 28=6
x=6/sin 28=12.78 ft.
By taking <span>logarithmic of base 10
∴ </span><span>
∴ x log 4 = log 64
∴
∴ The correct choice is
</span><span>x = log base 10 of 64, all over log base 10 of 4</span>
Answer:
Step-by-step explanation:
Consider polynomial
If x=-2 is its zero, then you can divide the polynomial by and get
If x=-1, then the polynomial can be rewritten as
The quadratic polynomial has roots
Then the polynomial has zeros
