Answer: 20
Step-by-step explanation:
Factors of 40: 1,2,4,5,8,10,20,40
Factors of 80: 1,2,4,5,8,10,16,20,40,80
Factors of 100: 1,2,4,5,10,20,25,50,100
The greatest common factor is 20
Answer:
It is A.
In function A we see that there are 2 ordered pairs with value 2 in the first position with y values 6 and 2. So this is not a function.
Answer: exponential
its exponential
count the squares in each one
first is 2 squares
second is 4 squares
third is 8 squares
this is going up exponentially because the first one would be 2^1 the second would be 2^2 and the third would be 2^3
Answer: no solution or zero solutions.
x3=y
Equation of the tangent to the curve
y = 240x - 215994
Equation of the normal
y = (-1/240)x + 9.75 = - 0.00417x + 9.75
y = (6 + 4x)² = 36 + 48x + 16x² = 16x² + 48x + 36
dy/dx = 32x + 48
At the point (6,900),
dy/dx = 32(6) + 48 = 240
Equation of the tangent at point (a,b) is
(y - b) = m(x - a)
a = 6, b = 900, m = 240
y - 6 = 240(x - 900)
In the y = mx + b form,
y - 6 = 240x - 216000
The slope of the normal line = -(1/slope of the tangent line) (since they're both perpenducular to each other)
Slope of the normal line = -1/240
Equation of normal
y - 6 = (-1/240)(x - 900)
y - 6 = (-x/240) + 3.75
y = (-1/240)x + 9.75
y = - 0.00417x + 9.75
