Answer:
Width of the arch = 105 m
Step-by-step explanation:
Function representing the width of the arch,
f(x) = -0.016(x - 52.5)² + 45
where x = width of the base of the arch or horizontal distance from arch's left end
f(x) = vertical distance of the arch
From the given quadratic function, vertex of the parabola is (52.5, 45).
Coordinates of the vertex represents,
Height of the arch = 45 m
Half of the horizontal distance from the left end = 52.5 m
Therefore, width of the bridge = 2(Half the width of the bridge from left end) = 2×52.5
= 105 m
Therefore, given bridge is 105 m wide.
Answer:
For which list does the total number have meaning? (What to see at the zoo)
For the list of facts it (does not) make sense to add the cost of a past, the area and the employees because these quantities (cannot) be expressed using the same unit. The number of 168 (does not) have meaning for the list
Step-by-step explanation:
Area is usually described in square feet while a population has no unit and a price is described in dollars therefore the list of facts has no meaning ( i got this question correct)
Answer:
4 mechanical pencils
Step-by-step explanation:
Each notebook is worth $2.99
So buying 3 of the notebooks would leave her with $8.97
Then, $15.00 - $8.97= $6.05
The inverse of the function is 
Explanation:
To find the inverse of the equation 
, we need to interchange the variables x and y for the variables y and x.
Thus, the equation becomes
Now, we shall find the value of y.
Now, adding 8 to both sides of the equation, we have,
Interchanging the sides,
Dividing by 2 on both sides,
Taking square root on both sides,
Thus, the inverse of the function is
