A truck driver drove 48 miles in 45 minutes.At this rate,how many miles can the truck drive in one hour?

murzikaleks [220]

Answer:

64 miles

Step-by-step explanation:

Number of miles driven in 45 minutes = 48 miles

We need to find how many miles will the truck drive drive in one hour. Since the rate is the same, the distance covered in each minute remains the same.

Number of miles driven in 1 minute = miles

Since, 1 hour = 60 minutes, we can write:

The number of miles driven in 1 hour (60 minutes) = miles

This means the truck driver can drive 64 miles in an hour.

HOPE THIS HELPS! :)

What is the exact value of tangent (negative StartFraction pi Over 3 EndFraction)

ExtremeBDS [4]

Answer:

tan(-π/3) = -1.732050808

Step-by-step explanation:

Given in the question, we have to find the value of tan(-pi/3) or it can be written as:

$x = tan(-\frac{\pi}{3})$

where x is the exact value of the given tangent.

However, in this question, one may get confused and put the value of π = 3.14, which is wrong. The value given is in radians, which is used to measure angles, just like degrees.

To make it easier, lets convert the radians into degrees. We know that

π = 180°

-π/3 = -180/3 = -60°

Find x:

x = tan (-60°)

x = -1.732050808

Prove 2√(x) + 1/√(x + 1) <= 2√(x+1) for all x in [0,inf)

EleoNora [17]

Start by multiplying each side of the inequality by $\sqrt{x + 1}$ and simplifying:

$2 \sqrt x + \frac{1}{\sqrt{x+1}} \leq 2 \sqrt{x + 1}$
$(2 \sqrt x + \frac{1}{\sqrt{x+1}})(\sqrt{x + 1}) \leq (2 \sqrt{x + 1})(\sqrt{x + 1})$
$2 \sqrt{x(x + 1)} + 1 \leq 2(x + 1)$
$2 \sqrt{x^2 + x} + 1 \leq 2x + 2$
$2 \sqrt{x^2 + x} \leq 2x + 1$
$\sqrt{x^2 + x} \leq x + \frac{1}{2}$

From here, we can square both sides to get

$x^2 + x \leq (x + \frac{1}{2})^2$
$x^2 + x \leq x^2 + x + \frac{1}{4}$
$0 \leq \frac{1}{4}$ , which is always true.
