Step-by-step explanation:
Third angle = 180° - (70° + 55°)= 180° - 125° =55°
Since, all the angles of triangle are acute angles, hence it is a acute angled triangle or scalene triangle.
(10c² +49cd+49d²) ÷ (5c+7d)
(5c+7d)(2c+7d) ÷ (5c+7d)
Delete (5c+7d)
= (2c+7d)
The answer is x1= 0, x2= 6
<span>This intersection produces a line. However, if the angle of the plane is less than the cone's angle, then the intersection produces a point. If the angle of the plane is greater than the angle of the cone, then the intersection is two lines intersecting at the vertex. If the plane intersects at some point other than the vertex, then the intersection is a circle if the plane is perpendicular to the cone's axis. It is an ellipse when the plane's angle is less than the cone's angle. It's a parabola when the planes's angle equals the cone's angle.</span>
Answer:
y = -2·(1/2)^x
Step-by-step explanation:
The ratio of one table entry to the one before is ...
(-2)/(-4) = 1/2
so this is the <em>growth factor</em>.
The <em>multiplier</em> is the value of y when x=0, which is -2. So, the equation is ...
y = (multiplier)·(growth factor)^x
y = -2·(1/2)^x
_____
This can also be written using a negative exponent:
y = -2·2^(-x)
