Answer:

(-1,0) and (2,0)

Step-by-step explanation:

Factor to get (x+1)(x-2)=0

Make at least one of the (x1+x2) equations equal 0.

-1 and -2 make them 0, so they are the x intercept.

Answer:

(-1,0) et (2,0)

Step-by-step explanation:

Facteur: (x + 1) (x-2) = 0

une des équations (x1 + x2) = 0.

-1 et -2 font 0, alors ils sont x

3 An open cone has a vertical angle measuring 40°
belka [17]

Answer:

13.41 cm

Step-by-step explanation:

The radius, height, and HALF of vertical angle makes a triangle.

Where

Radius will be the base of the triangle

Height will be the "height" of the triangle

Top angle will be HALF of vertical angle (40/2 = 20)

From the 20 degree angle, the side "opposite" would be the radius, which is 30. The side "adjacent" would be the height, let it be h.

<em>Which trig ratio relates opposite and adjacent? Yes, that is TAN. Thus we can write:</em>

Tan(20) = opposite/adjacent

Tan(20) = 30/h

h = 30/Tan(20)

h = 13.41

So

The height of the cone would be around 13.41 cm

Please answer asap!!!!!!!!!!!!!!!!!!!!!!!!!
Nitella [24]

Answer:

x = 90

Step-by-step explanation:

The 90-degree angle and "x" form a straight line. The degree measurement of a straight line is 180. That means that if one adds 90 and "x", they will get 180, and therefore, x equals 90.

A circle is centered at the point (3, 2) and the length of the radius is 5. What is the equation of the circle?
VMariaS [17]

\bf \textit{equation of a circle}\\\\ (x- h)^2+(y- k)^2= r^2 \qquad center~~(\stackrel{3}{ h},\stackrel{2}{ k})\qquad \qquad radius=\stackrel{5}{ r} \\\\\\ (x-3)^2+(y-2)=5^2\implies (x-3)^2+(y-2)=25
