Help me please I would really appreciate it

o-na [289]

Step-by-step explanation:

The coordinates of the points are P1(2, 2) and P2(10, 2). The distance <em>d</em><em> </em> between these two points are given by

$d = \sqrt{ {(x\frac{}{2} - x\frac{}{1} ) }^{2} + ({y\frac{}{2} - y\frac{}{1}) }^{2} } \\ = \sqrt{ ({10 - 2})^{2} +( {2 - 2)}^{2}} \\ = 8$

19. What is the lateral area of the cone to the nearest whole number? The figure is not drawn to scale.

STatiana [176]

Answer:

Lateral area of the cone = 4,712 m (Approx)

Step-by-step explanation:

Given:

Height of cone (h) = 40m

Radius (r) = Diameter / 2 = 60 / 2 = 30m

Find:

Lateral area of the cone = ? ?

Computation:

$Slant\ height(l) =\sqrt{h^2+r^2} \\\\ Slant\ height(l) =\sqrt{40^2+30^2} \\\\ Slant\ height(l) =\sqrt{1,600+9,00} \\\\ Slant\ height(l) = 50m$

$Lateral\ area\ of\ the\ cone =\pi rl\\\\ Lateral\ area\ of\ the\ cone = \frac{22}{7}(30)(50)\\\\Lateral\ area\ of\ the\ cone= 4,712 (Approx)$

Find the equation of a line perpendicular to y - 1= -x that passes through the

Goryan [66]

Answer:

Step-by-step explanation:

firstly you separate y

y=-x-1

which means that the slope is equal to -1

then you flip the slope so -1 over -1 which is equal 1

Suppose that events a and b are mutually exclusive with p(a) = ½ and p(b) = ⅓.

irina1246 [14]

No, a & b are not independent if they're mutually exclusive.

Mutually exclusive means the two events cannot occur simultaneously. So if "a" happens "b" cannot. In contrast, two events are independent if the occurrence of one has no effect on the occurrence of the other.
