Answer:
j= -4,6
Step-by-step explanation:
j^2 -2j -24 =0
Factor
What 2 numbers multiply to -24 and add to -2
-6*4 = -24
-6+4 = -2
(j-6) (j+4) =0
Using the zero product property
j-6 =0 j+4 =0
j =6 j=-4
A=AB*DE=(8+4)*7=12*7=84 m^2
A=84 m^2
First we need to find out the volume of one cylinder. We already know the volume of the block of gold is 360cm3
V = Pie * radius squared* height.
Pie is 3.142
radius is 6.18/2 = 3.09 cm
height is 6cm
V = 3.142 * 3.09 * 3.09 * 6
V = 180cm3
Now we divide the volume of this cylinder with the volume of block of gold.
360/180 = 2
So it will take 2 cylinders to mold one block of gold.
3/4 is greater. you have to change the 3/4 to 12/16 which proves that 3/4 is greater than 11/16
product of 4/5 and 5/7 is 4/7
Answer:
B. (x, y) → (-x,-y)
This rule is given triangle is reflection about origin or
Rotation clockwise or counter clock wise with 180°
Step-by-step explanation:
<u>Explanation:-</u>
A triangle has coordinates at X(3,7),Y(6,7) and Z(4,2)
The Rule ( x, y)→ ( - x, -y)
<em>This rule is given triangle is reflection about origin or Rotation clockwise or counter clock wise with 180°</em>
X( 3,7) → X¹ ( -3,-7)
Y(6,7) → Y¹ (-6,-7)
Z(4,2) → Z¹( -4 ,-2)
