Answer:
19
Step-by-step explanation:
3 to the power of 2 is 9
5 times 2 is 10
10 plus 9 is 19
you can easily solve it by equating the fractions 4/13 and x/91
here, we suppose x as the number of people who can bowl.
4/13=x/91
or, 4/13×91=x (divide 91 by 13)
or, x=4×7
therefore, x=28
easy peesy lemon squeezy ;-)
<span>3(7 + 4)2 − 14 ÷ 7
First do the parenthesis
7 + 4 = 11
so the question looks like: 3(11)2 - 14/7
Then multiply 3, 11, and 2 together
3 x 11 x 2 = 66
66 - 14/7
14/7 equals to 2
66 - 2
Then just simplify
66 - 2 = 64
64 is your answer

Answer:
Its 11x + 20 !!
Step-by-step explanation: :)
Answer:
a) Domain: all real values of x
Range: all real values of y
b) Relative maxima: (0,3)
Relative minima: (2,-1)
c) yes, (1,1)
d) x < 0, x > 2
Step-by-step explanation:
a) Domain: all real values of x
Range: all real values of y
b) dy/dx = 3x² - 6x = 0
3x(x - 2) = 0
x = 0, y = 0³ - 3(0)² + 3 = 3
x = 2, y = 2³ - 3(2)² + 3 = -1
d²y/dx² = 6x - 6
x = 0, d²y/dx² = -6 < 0 (max)
x = 2, d²y/dx² = 6 > 0 (min)
c) d²y/dx² = 0 at points of infection
6x - 6 = 0
x = 1
y = 1³ - 3(1)² + 3 = 1
dy/dx at x = 0.9: 3(0.9)² - 6-(0.9)
= -0.298
dy/dx at x = 1.1: 3(1.1²) - 6(1.1)
= -0.297
Decreasing on both sides, therefore (1,1) is a point of inflection
d) increasing when dy/dx > 0
3x² - 6x > 0
Roots: x = 0, 2
x < 0, x > 2
