Hitman42 [59]

Answer:

The height of the arch 50ft from the center is 97ft

Step-by-step explanation:

A bridge over a gorge is supported by an arch in the shape of a semi-ellipse

The length of the bridge is 400 ft. and the maximum height is 100 ft

so, a=200ft

b=100ft

(a)

we can draw picture

(b)

now, we can use equation of ellipse formula

$\frac{x^2}{a^2}+ \frac{y^2}{b^2}=1$

now, we can plug

a=200

b=100

$\frac{x^2}{200^2}+ \frac{y^2}{100^2}=1$

we can plug x=50 and find y

$\frac{50^2}{200^2}+ \frac{y^2}{100^2}=1$

$y=25\sqrt{15}$

$y=97ft$

If f(1) = 1 and f(n + 1) = 5f(n) + 3 then find the value of f(4).

FrozenT [24]

Answer:

218

Step-by-step explanation:

Because we need f(n) to calculate f(n+1), we have to calculate our values one step at a time. Starting with f(1) = 1,

f(2) = 5(f(1)) + 3 = 5(1) + 3 = 5+3 = 8

f(3) = 5(8) + 3 = 40 + 3 = 43

f(4) = 5(43) + 3 = 215 + 3 = 218
