So, put your "x's" together first and then your intercepts. That should answer your question :)
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: C) $1951.53
<u>Step-by-step explanation:</u>
- A is amount accrued (final balance)
- P is the Principal (original amount deposited)
- r is the rate (in decimal form)
- t is the number of years
A=1500(1+0.068)⁴
= 1500(1.068)⁴
= 1951.53
