Answer:
4
Step-by-step explanation:
First things first we will need to solve the square root.
We can check this by squaring 2.
= 2 x 2 = 4
Now that we have solved the square root, we are left with 2(2). 2 x 2.
2(2) = 4
2 = ?
2(2) = ?
4
Answer:
It will take 1.5 hours to paint the room together
Step-by-step explanation:
Martha can paint a room in 2 hours. Jamie can paint the same room in 6 hours.
Work done by Martha in 1 hour =
Work done by Jamie in 1 hour =
Work one together in 1 hour =
Now take common denominator to add both fractions
LCD = 6, Multiply the first fraction by 3
Now add the numerators
To find total hours of painting together, we take reciprocal of 2/3
Time taken to paint together =
It will take 1.5 hours to paint the room together
Answer:
The x intercept is (-5,0)
The y intercept is (0,-3)
Step-by-step explanation:
To find the x intercept we set y=0 and solve for x
3x+5y = -15
3x+0 = -15
3x = -15
Divide by 3
3x/3 = -15/3
x = -5
The x intercept is (-5,0)
To find the x intercept we set x=0 and solve for y
3x+5y = -15
0+5y = -15
5y = -15
Divide by 5
5y/5 = -15/5
y = -3
The y intercept is (0,-3)
... angle 1
k = x²+1
dk/dx = 2x
dk = 2xdx
y = (x²+1)³ = k³
dy/dk = 3k²
dy/2xdx = 3k²
dy/dx = 2x(3k²) = 6x(x²+1)²
... angel 2
dy/dx = d[(x²+1)³]/dx
= { d[(x²+1)³]/dx }(d(x²+1) / d(x²+1))
= { d[(x²+1)³]/d(x²+1) }(d(x²+1) / dx )
= { 3(x²+1)² }(2x) = 6x(x²+1)²
Answer:
y=3x-16
Step-by-step explanation:
-3y=-9x+27
y=3x-9
slope: 3
y-2=3(x-6)
y-2=3x-18
y=3x-16
