A quadratic equation for the large cables is [tex]f(x) = \dfrac{87 }{512072} \cdot x^2 + 1.5[/tex]

Step-by-step explanation:

The shape of the quadratic equation representing the large cables is a parabola

Taking the point of the smallest vertical cables as the vertex, (h, k) with coordinates, (0, 1.5), we have;

h = -b/(2·a)

∴ 0 = -b/(2·a), from which we have, b = 2·a × 0 = 0

k = 1.5 = c - (b²/(4·a) = c - (0/(4·a)) = c

∴ c = 1.5

The standard form of the quadratic equation, a·(x - h)² + k is therefore, given as follows;

f(x) = a·(x - 0)² + 1.5 = a·x² + 1.5

At the towers which are on either side of the bridge, when x = 1012/2 = 506, f(x) = y = 45

Therefore, we have;

45 = a·506² + 1.5

a = (45 - 1.5)/506² = 87/512072 ≈ 1.699 × 10⁻⁴

The quadratic equation for the large cables, f(x), can therefore be presented as follows;

[tex]f(x) = \dfrac{87 }{512072} \cdot x^2 + 1.5[/tex]

Answer:

1868 is the answer your looking for

Step-by-step explanation:

Answer:

1868

In 1868, the position of county commissioner was added to the elected officials of a county.

Answer:

They are the same line.

Step-by-step explanation:

y = -1/3x - 2

-x - 3y = 6

First, we need both lines to follow the equation of y = mx + b so that we can graph them. We already have one equation in that form (the one from the graph given), so we can ignore that for now.

Next, we need to solve -x - 3y = 6. Let's first move the x to the other side of the equal sign.

-3y = x + 6

Now, since we have a similar equation to what we need, we just need to divide the y by the given number in front (or -3). But that also means that we must divide the other side by the same amount (or each variable).

-3y = x + 6. -> y = -1/3x - 2

So, your final equation for -x - 3y = 6 should be;

y = -1/3x -2

Bringing down the other equation, we get:

y = -1/3x - 2 and y = -1/3x - 2

Making both equal to each other (they cancel each other out).

Hope this helps!

Answer:

ANNUAL Compounding : Total = Principal * (1 + rate)^years

Semi-Annual TOTAL = Principal * (1 +rate/n)^n*years

where "n" is the number of compounding periods per year

So the formula for semi-annual compounding is

TOTAL = Principal * (1 +rate/t)^t*years

What snacks can they buy? if Susan and James don't know that they must be slow, might as well not even buy snacks if they can't figure that out.

Step-by-step explanation:

______________________________

 - We do this because we have to get 2 variables/numbers on each side of the equals, and the only way to do so is to cancels other numbers out by doing the opposite of what we see.

Answer: $200

Step-by-step explanation:

Since there is a deductible here, you deduct it from the total bill first:

= 2,000 - 1,000

= $1,000

With an 80/20% coinsurance plan, you will pay for 20% of this bill and your insurance company will pay 80%.

You will therefore pay:

= 1,000 * 20%

= $200

Answer:

24mph

Step-by-step explanation:

24 mph times 5 hours = 120 miles

24 mph + 36 mph = 60 mph

60 mph × 2 hours = 120 miles

Answer:

n<50

Step-by-step explanation:

7/2*5n + 14<49

7n/2*5+14<49

(7n)+(2*5)14/2*5 <49

7n+10*14/2*5 <49

7n+140/2*5 <49

7n+140/10 <49

7n+140 < 10*49

7n+140 < 490

(7n+140)+(-140)<490+(-140)

7n+140-140<490-140

7n<350

7n/7 < 350/7

n<2*5^2*7/7

n<2*5^2

n<2*25

n<50

B. 20 = 2g

Step-by-step explanation:

What we see here is a diagram showing a bar of 20 at the top, and a pair of g's bars each taking up half of the 20 bar.

Seeing this, that would mean the 2 bars showing g equal 20, so the equation 20 = 2g is the one which the diagram shows.

Step-by-step explanation:

Answer: They would paint 36 props in 3 hours.

Step-by-step explanation:

Given: The squad painted 18 props in 90 minutes.

Time taken to paint each prop = [tex]\dfrac{90\text{ minutes}}{18}[/tex]

= 5 minutes

Now, 1 hour = 60 minutes

3 hours = 3 x 60 minute = 180 minutes

Total props painted in 3 hours = (180 )÷5

= 36

Hence, with same rate , they would paint 36 props in 3 hours.
