For $f(x+h) - \dfrac{f(x)}{h}$ reading the fraction like f(x)/h only (f(x+h) start fraction f(x) / h end fraction), the answer is $-x^2/y + x^2 + 2x + y + y^2 - 1/y + 1$

Round 4806 to the nearest 1000?

grandymaker [24]

If you want to round to the nearest thousand, you cannot look at the thousands place to round. You will have to look at the number in the hundreds place. The rules of rounding are
<em>5 and above-round up. Example-2743. 7 is greater than 5, so 2743 rounded to the nearest thousand is 3000.
</em>
<em>4 and below-round down. Example-4390. Three is less than 5, so 4390 rounded to the nearest thousand is 4000.
</em>
Apply these rules to your problem. 8 is greater than 5. So we will round up. You get 5000.<em>

Bob is driving along a straight and level road toward a mountain. At some point on his trip, he measures the angle of elevation

DerKrebs [107]

Answer:

Option A.

Step-by-step explanation:

Distance between Bob and the center of the mountain at the base = 19,427.5 ft.

Angle of elevation to the top of the mountain = 25°11'

We know that

1 degree = 60 minutes

1/60 degree = 1 minute

$25^{\circ}11'=25^{\circ}+\frac{11}{60}{\circ}\Rightarrow 25^{\circ}+0.183^{\circ}=25.183^{\circ}$

Let the height of the mountain be h.

In a right angled triangle

$\tan\theta = \frac{opposite}{adjacent}$

$\tan(25.183^{\circ}) = \frac{h}{19427.5}$

$\tan(25.183^{\circ})\times 19427.5 = h$

$h=0.4702\times 19427.5$

$h=9134.8105$

$h\approx 9135$

Therefore, the height of the mountain to the nearest foot 9135. Option A is correct.
