Given f(x) = x ^ 2 - (3x + 8) Find f(1)

1 answer:

3 0

Answer:this problem requires one to plug in the value given to the equation given. to find f(-1) the x in one side of the equation is replaced by a -1 therefore the x in the other side of the equation must also be replaced by (-1) so the answer is -3(-1) -8 = f(-1) = -5. -5 is the correct answer.

An artist is creating a sculpture where a globe with a diameter of 48 inches sits in a cone like a scoop of ice cream. She wants

brilliants [131]

Answer:

115.2 inches

Step-by-step explanation:

What we must do is calculate the ratio between the real version and the version to be imitated, in this case the ice cream cone.

To calculate the ratio, we will do it through the diameter:

48 / 2.5 = 19.2

So the ratio is 19.2: 1

Which means that one inch of the ice cream cone represents 19.2 inches in the real version.

Therefore, in the case of height it would be:

6 * 19.2 = 115.2

Therefore, the height should be 115.2 inches.

How do you find magnitude of a vector

Otrada [13]

Draw a vector triangle. When you draw the horizontal and vertical components, you end up with a right triangle. The magnitude of the vector is equal to the hypotenuse of the triangle so you can use the Pythagorean theorem to calculate it. Rearrange the Pythagorean theorem to calculate the magnitude
