The answer is C.

If Sergio is 'S' years old, and you want to know how old he'll be in 7 years, add 7 years to his age.

So: s + 7

Hope this helps!

The profile of the cables on a suspension bridge may be modeled by a parabola. The central span of a bridge is 1270 ft long and

deff fn [24]

Answer:

Step-by-step explanation:

Given

span of bridge $L=1270\ ft$

height of span $h=157\ ft$

Equation of Parabola

$y=0.00039x^2$

$|x|$ i.e.

$-635$

$\frac{dy}{dx}=2\times 0.00039$

length of Arc $=\int_{a}^{b}\sqrt{1+(\frac{dy}{dx})^2}$

$=\int_{-635}^{635}\sqrt{1+(\frac{dy}{dx})^2}$

$=\int_{-635}^{635}\sqrt{1+(0.00078x)^2}$

$=2\times \int_{0}^{635}\sqrt{1+(0.00078x)^2}$

$=2\times (660.08)$

$=1320.16\ ft$

What is the sum of the first eight terms of the series?

Ray Of Light [21]

Observe that as the series progresses, the term decreases by 1/4. To show this, observe the first four terms of the series below.

-200 = (1/4)(-800)
-50 = (1/4)(-200)
-12.5 = (1/4)(-50)

Since we have a common ratio, r, of 1/4, we can use the properties of a geometric series to find the 8th term of the series.

Recall that to find the sum of the nth term of a geometric series, we have

$S_{n} = a(\frac{1-r^{n}}{1-r})$

where a is the first term of the series and r is the ratio.

So, for the first eight terms, we have

$S_{8} = -800(\frac{1-(\frac{1}{4})^8}{1- \frac{1}{4}})$
$S_{8} \approx -1066.65$

Therefore, the sum of the 8th series is approximately -1066.65.

Answer: -1066.65
