Shouldn’t there be a picture?
Answer:
450 feet at ground level
Step-by-step explanation:
The width of the bridge at ground level will be where the function intercepts the x-axis also known as the roots or zeros of the function. They are found using the zero product property to set each factor equal to 0.
This means (x-225) = 0 and (x + 225) = 0. So x = -225, 225.
This means the width is the absolute value of |-225| + 225 since distance cannot be negative. This makes it 450 feet.
Answer:
cos(71)
Step-by-step explanation:
Since 19° is less than 90, we can express this in terms of confunction.
sin(θ) = cos(90-θ)
sin(19) = cos(90-19)
sin(19) = cos(71)
They are each .20 cents because you always divide the cost over the amount so 4.80 divided by 24 and it’s .20 cents! Hope this helps!
Answer:
(AD)=SQRT(20n^2+34-4n)
Step-by-step explanation:
let the point of intersection between AC and DB be O. Then the length of OA is the same as that of OC which is=2n+5
Similarly the length of DO is the same as that of OB which is=4n-3
Now from Pathagoras theorem we get
(AD)=SQRT((DO)^2+(OA)^2)
(AD)=SQRT((4N-3)^2+(2N+5)^2)
(AD)=SQRT((16n^2+9-24n)+(4n^2+25+20n))
(AD)=SQRT(20n^2+34-4n)
