What is the diagonal length of a square that has a side length of 10 cm? I DON'T KNOW THIS!!

Answer: 14.142

Explanation: What happens when you cut a square diagnally? You get a triangle. What’s the diagonal value? We don’t know. This is like Pythagorean theorem where we solve using a squared + b squared = c squared. Since it’s a perfect square, you put in 10 values for a and b and solve for c. What you get from finishing the formula is 14.142. Correct me if I’m wrong btw.

Hope this helps!!!

Let u=ln x and v= ln y. Write ln(square root x times y^2)

Alex Ar [27]

0.5u + 2v. This is because u can separate the logs to ln(sqrx) + ln(y^2) and use basic log principles to get 0.5lnx +2lny. Then u substitute

➷ Find the cost per candy:

90/1000 = 0.09

Multiply this by the number of candy pieces you need:

0.09 x 10 = 0.9

They would cost $0.90

The boat shown in the accompanying figure is 3 miles from both lighthouses and the angle between the line of sight is 20 degrees

muminat

Answer: $1.04\ miles$

Step-by-step explanation:

Observe the figure attached.

You can identify that the triangle formed is Isosceles, because it has two equal sides.

Notice that you can divide it into two equal right triangles. Now the angle 20° is divided by 2 and you get two equal angles that measure 10°.

To find "x", apply the Trigonometric Identity $sin\alpha=\frac{opposite}{hypotenuse}$ :

$sin(10\°)=\frac{x}{3}\\\\x=3*sin(10\°)\\\\x=0.52\ miles$

Then, the distance between the lighthouses can be represented with:

$d=2x$

Substituting the value of "x" into this equation, you get:

$d=2(0.52\ miles)\\\\d=1.04\ miles$
