Answer + brainliest ! the arch of the bridge is modeled by the equation y = -0.00092x^3 + 434, where y is the height above the water’s surface, in feet, and x is the distance from the middle of the bridge, in feet. what is represented by an x-intercept in this situation? a. the middle of the arch b. the maximum height of the arch c. the point where the arch of the bridge touches the ground d. the maximum height of a sailboat that passes under the bridge

c

Step-by-step explanation:

step 1  look at the graph and find all three points of the bridge

step 2combine both x-intercepts

690+(-690)=o

step 3 plug points in for the varibles  y=-0.00092 x 0^3 +434

step 4 do the pemdas rule to simplafi the equation  y=-0.00092 x 0 + 434

step 5 solve for y y=434

step 6 check your answer by pluging the answer for y. (attachment below has the steps you take to check your answer)

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
