Answer:
u(x) = –x + 3x2 – 8
Step-by-step explanation:
The functions are;
u(x) = –x + 3x2 – 8
v(x) = 2x2 + 8x3 + 9x
y(x) = x2 + 3x5 + 4
z(x) = 7x2 + 2x3 – 3
A quadratic function is a function that has the form f(x) = ax2 + bx + c where a, band c are numbers with a not equal to zero. The maximum degree must be 2.
Among all the options, the one that matches the form is;
u(x) = –x + 3x2 – 8
Answer:
u(x)=-x+3x2-8

Alonzo charges $150 for 5 hours of tutoring.
What is his rate per hour.
I’m confused
Answer:
C: $30/hr
Step-by-step explanation:
In order to find the rate per hour you must divide: 150 ÷ 5
Which will give you 30
Also if you took away the 0 in "150" then it would be like says "15 ÷ 5" which is 3 but then you have to add the zero back making it 30
Therefore your overall answer is going to be C, $30/hr

find the surface area of a cylinder with a height of 9 inches and a base radius of 4 inches
answer:
104π or 326.56 inches^2
step-by-step explanation:
know the surface area formula for a cylinderonce you know that plug in the numbers givenformula: 2πrh+2πr^2
r stands for radiush stands for heightπ stands for pi- now that you know that, plug in
2πrh+2πr^2
2π(4)(9) + 2π(4)^2
72π + 32π
104π
the answer would be 104π inches^2you can further solve this by multiplying by 3.14 instead of putting πA vendor sells 18 greeting cards in an hour. Some of the cards have photographs on them. Others have
