PLEASE HELP ME thank you<br><br> answer needs to be in simplest radical form <br><br> find d

sweet [91]

Answer:

$d=10$

Step-by-step explanation:

Pythagorean theorem:

$d^2+d^2=10\sqrt{2}^2,\\2d^2=200,\\d^2=100,\\d=\boxed{10}$

Alternative:

$\cos 45^{\circ}=\frac{d}{10\sqrt{2}},\\\frac{\sqrt{2}}{2}=\frac{d}{10\sqrt{2}},\\2d=10\sqrt{2}\cdot \sqrt{2},\\2d=20,\\d=\boxed{10}$

Alternative (derived from the Pythagorean theorem):

All 45-45-90 triangles have side lengths $x-x-x\sqrt{2}$ , where $x\sqrt{2}$ is the hypotenuse. Since this triangle's hypotenuse is $10\sqrt{2}$ , its sides are $10-10-10\sqrt{2}$ .

You and your friend leave your houses at the same time to meet at a restaurant. The distance (in miles) your friend is from the

laila [671]

Answer: y = - 60 x +150

Step-by-step explanation:

Here, the function which represents the distance between my friend and restaurant,

y = - 40x +100

Where, x is the number of hours since my friend left home.

Since, when he covered the whole distance y = 0

Then -40x +100 = 0

⇒ -40x = -100

⇒ x = 2.5

Thus, he is taking 2.5 hours to covered the whole distance.

And, According to question, me and my friend take the same time to covered the distance.

Thus, the time taken by me to covered 150 miles distance = 2.5 hours.

Therefore, my speed = 150/2.5 = 60 miles per hour.

Thus, in x hour the distance between me and restaurant,

y = 150 - 60x

Which is the required equation.

Use each of the five digits $2, 4, 6, 7$ and $9$ only once to form a three-digit integer and a two-digit integer which will be m

VLD [36.1K]

Answer:

The 3 digit number 642 when multiplied 97 gives the greater product.

Step-by-step explanation:

The greatest product will result by multiplying the smaller 3 digit number with the greater two digit number.

The greater three digit number will be 976 and smaller 2 digit number would be 42

Multiplying

976*42 = 40992 ( descending order number)

679 *24= 16,296 ( ascending order number)

If we take the 2 digit number as 97 and 3digit number 642

Then multiplying

642* 97= 62,274 ( descending order number)

246 * 79=19434 ( ascending order number)

The 3 digit number 642 when multiplied 97 gives the greater product.

What is the distance from the point (a, −b, −4) to the origin?

laiz [17]

Answer:

$\sqrt{a^2+b^2+16}$

Step-by-step explanation:

The distance (d) between two points in 3 dimensions is ...

d = √((x2 -x1)² +(y2 -y1)² +(z2 -z1)²)

Then the distance between (a, -b, -4) and (0, 0, 0) is ...

d = √((a -0)² +(-b -0)² +(-4 -0)²)

= √(a² +b² +16)
