What are the solutions to the equation?
Phantasy [73]

Answer:

x = -2 and 1

Step-by-step explanation:

Given :

f(x) = x+2

g(x) = -x²+4

The solution to the equation f(x) = g(x)

=> x+2 = -x²+4

=> x²+x = 4-2

=> x²+x -2 = 0

By factorisation

=> x²+2x-x -2 = 0

=> x(x+2) -1(x+2)

=> (x+2) (x-1)

x = -2 and 1

What is the volume of a cone that has a height of 7 mm and a radius of 3 mm?
vaieri [72.5K]
<span>So we want to know the volume V of a cone with a height h=7 mm and of radius r=3 mm rounded to the nearest hundreth. We need the formula for the volume of a cone: V=(1/3)*pi*r^2*h. Now we simply input the numbers and get: V=65.94 mm^2 and that is rounded to the first hundreth.</span>

P+45267=87012 evaluate
Rainbow [258]
Answer:

p+45267=87012

We move all terms to the left:

p+45267-(87012)=0

We add all the numbers together, and all the variables

p-41745=0

We move all terms containing p to the left, all other terms to the right

p=41745

The coordinates of point D are (7, 4) and the coordinates of point E are (1, −3) . What is the slope of the line that is perpend
Katarina [22]
The slope of a line is given by the change in y coordinates over the change in x coordinate.
The slope of line DE will be (4 - -3)/ (7-1) = 7/6
If M1 and M2 are slopes of two perpendicular lines at a point then
 M1× M2 = -1
 Thus, the slope of a perpendicular to line DE will be -6/7.
