What is this in vertex form
Lyrx [107]

Answer:

(x + 1)² + 4

Step-by-step explanation:

the equation of a parabola in vertex form is

y = a (x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

to obtain this form use the method of completing the square

• add/subtract (half the coefficient of the x-term)² to x² + 2x

= x² + 2(1)x + 1 - 1 + 5

= (x + 1)² + 4 ← the second option

A hiker leaves camp and walks 6 miles east. Then he walks 18 miles south. How far from camp is the hiker? Distance in miles: Usi
Mrac [35]

Answer: 19 miles

Step-by-step explanation:

Hi, since the situation forms a right triangle (see attachment) we have to apply the Pythagorean Theorem:  

c^2 = a^2 + b^2  

Where c is the hypotenuse of the triangle (in this case the distance between the hiker and the camp) and a and b are the other sides.  

Replacing with the values given:  

x^2 = 6^2 + 18^2  

x^2 = 36+324

x^2 = 360

x = √360

x = 18.97miles = 19 miles

Feel free to ask for more if needed or if you did not understand something.

Calculate the force of gravity on earth of an object that has a mass of 200 kg. A. 1,962 N B. 123 N C. 20 N D. 326 N
leonid [27]

For this case we have that by definition, the gravity of the earth is given by:

g = 9.807 \frac {m} {s ^ 2}

On the other hand, Newton's second law states:

F = M * g

Where:

F: It's the force

M: It's the mass

g: Acceleration of gravity

F = 200 * 9.807\\F = 1961.4 \ N

Answer:

Option A
