Answer:
Let x be her initial distance from the building, then tan 37 = 130/x
x = 130/tan 37 = 130/0.7536 = 172.5 feet
Let y be her distance from the building after moving forward, then
tan 40 = 130/y
y = 130/tan 40 = 130/0.8391 = 154.9
After moving forward, she is 172.5 - 154.9 = 17.6 ft closer.
Answer:
m = - 1/4
Step-by-step explanation:
When two line is perpendicular to each other the product of them is - 1
So let the other line be B
Gradient of B = t
Gradient of A = 4

therefore m = - 1/4
Answer:
the age of daughter is 28yrs
The function is a quadratic function, then the domain will be all real numbers. Then the correct option is D.
<h3>What are domain and range?</h3>
The domain means all the possible values of x and the range means all the possible values of y.
The function is given below.
y = -2x² + 50x + 300
Then the function is a quadratic function, then the domain will be all real numbers.
Then the correct option is D.
More about the domain and range link is given below.
