The function h represents the height of the bridge, in feet, and x represents the distance along the base of the model from the
Tanya [424]
H(x)=-0.5(x-4)^2+2

h(x)=0→-0.5(x-4)^2+2=0
Solving for x:
-0.5(x-4)^2+2-2=0-2
-0.5(x-4)^2=-2
-0.5(x-4)^2/(-0.5)=-2/(-0.5)
(x-4)^2=4
sqrt [(x-4)^2]=+-sqrt(4)
x-4=+-2
x-4+4=+-2+4
x=4+-2
x1=4-2→x1=2
x2=4+2→x2=6

Answer: Second option. The brigde touches the base of the model at 2 feet and 6 feet from the leftmost edge of the model

Which inequality is true when the value of d is 14?
shutvik [7]

Answer:

-d - 9 < 1.5

Step-by-step explanation:

In this problem, my reasoning is shown below for each individual inequality. We can test each one to see if it is true or not.

-(14)-9>1.5?\\-14-9>1.5?\\-23>1.5?\\

-23 is not greater than 1.5, so it can't be the first one. Let's try the next one.

-(14)-9

Yes! -23 is smaller than 1.5. So we can say that the second option is correct. But just for good measure, we can try the other two.

-(14)-9>1.5?\\-14-9>1.5?\\-23>1.5?

Nope! -23 is not greater than 1.5. Let's try the last one.

14-9

And again... nope. 5 is not smaller than -1.5. So our reigning option is -d - 9 < 1.5. Hopefully this was helpful! If you have any more questions, let me know.
