Answer:
13 units
Step-by-step explanation:
d = √(x₂ - x₁)² + (y₂-y₁)²
= √(-8-4)² + (2 - (-3))²
= √(-12)² + (5)²
= √144 + 25
= √169
= 13 units
Area = Base x Height
= (x-4) * ( 2x² +2x -6 )
= 2x³ +2x² -6x -8x² -8x+24
Area = 2x³ -6x²-14x +24 square centimeter
the second answer
Braddock should prepare 6 test tubes.
Given:
cylinder:
height = 40mm
radius = 12 mm
pi = 3.14
volume of test tube = 3014 mm³
We need to get the volume of the cylinder to know how much saline solution it holds.
Volume = π r² h
= 3.14 * (12mm)² * 40mm
= 3.14 * 144mm² * 40mm
Volume = 18,086.40 mm³
To get the number of test tubes used: we need to divide the volume of the cylinder by the volume of the test tube.
18,086.40mm³ / 3014mm³ = 6 test tubes.
It’s just a change of sign. For example y+-1(x+2) or y-x-2 or y-(x+2) all the same thing
Answer:
<em>a = 6 </em>
Step-by-step explanation:
g(x) = 5x - 2
h(x) = √(x + 3)
g(h(x)) = 5 - 2
g(h(a)) = 5 - 2
5 - 2 = 13
5 = 15
= 3
( )² = 3²
a + 3 = 9
<em>a = 6</em>
