The vertex can be found at x=0, i.e, h=290. The vertex tells us that the bridge is 290 ft. high at its' midpoint. The max width is when y=0, or, in other words:
0.0159x²=290
x²=290/.0159= 18239
x=±135.05
The distance between the feet of the arch is 2x135.05, or 270.10

adelina 88 [10]
The degree of the polynomial is 2.

to find the degree, put the polynomial in descending order with the highest exponents in front.  the highest exponent is the degree.

3x^6 - 4    (highest exponent here is 6, degree would be 6)

If BY = 6, YC = 10, AX = 18, then XC = <br> a: 10.8 <br> b:5 <br> c:30 <br> d:48
vampirchik [111]
To answer this item, we assume that the topic is in similar polygons such that the ratio of the corresponding sides should be equal. In this item,

    BY/YC = AX/XC

Substituting the known values,

    6/10 = 18/XC

The value of XC from the equation is 30. The answer is letter C.

If 10% of x is 30, what is 23% of x <br> A. 33<br> B. 46<br> C. 200<br> D. 230
aliina [53]

Answer:

69

Step-by-step explanation:

I'm mathematics, the word 'of' transfers into becoming 'times or Multiply'

Therefore, the expression can be rewritten as:

10/100 of x = 30

10x / 100 = 30

Cross Multiply the equation to solve for x

10x = 100 * 30

10x = 3000

x = 3000 / 10

x = 300

(Since we gotten the value of x as 300) let's find 23% of it.

Therefore,

23% of x, ( when x is 300)

= 23/100 * 300

= 23 * 3

= 69

(Well, although that's the workable solution, the option doesn't seen to tally)

Maybe you check the source, but am certain about the Solution.

Let's keep learning, maths is fun !
