Answer:
C.
Step-by-step explanation:
The zeros of a polynomial are the x-intercepts of the function. To find them, we factor the polynomial and set each factor equal to 0.
This polynomial is already factored so set each to 0 and solve for x.
This means x=-2, 5. Each zero or root has a multiplicity - the number of times the factor occurs. This is also known as the exponent of the factor expression.
(x+5) occurs once since it has exponent 1.
occurs twoce since it has exponent 2.
x=5 mult. 1, x=-2 mult. 2
The answer is 7 1/2 becasue if you add the whole #s then the fractions you get the answer
im guessing this is what you're asking for
9(1(5))
the answer is 45
1) You know the height of the bird from the observer is the same as the height of the plane to tower. We also know that the angle of depression is same as the angle of elevation.
So we will use the tangent function to find the value of x.
tan 23 = 5000 / x
x = 5000 / tan 23
x = 11779
You're answer will be 11779 feet
2) We will use the sine function.
sin 35 = 17,000 / x
x = 17,000 / sin 35
x = 29638.6
So the answer would be approximately 29639
Answer:
x = 10°
Step-by-step explanation:
If Angles 1 and 2 are complementary, then:
Angle 1 + Angle 2 = 90°
Since Angle 2 = 65°, Angle 1 + 65° = 90° → 3x - 5 + 65° = 90°, or
3x + 60° = 90°
Then 3x = 30, and x = 10
