The first one (top left) is a function. Use the vertical line test, if a vertical line crosses the line drawn on the graph twice, then it's not a function.
Answer:
60
Step-by-step explanation:
1. Calculate area of front surface:
Area of rectangle + Area of smaller rectangle
6*3 + 2*1 = 20
2. then multiply the area by the depth (3)
20 * 3 = 60 cm^3
I am extremely bad at math and I am trying to help other to ask a question, but I personally think C
Answer:
-2(1.5h + 5) - 4(-0.5 + 3h) = -15h-8
Step-by-step explanation:
-2(1.5h + 5) - 4(-0.5 + 3h)
-2*(1.5h)+(-2*5)-(4*-0.5)-4(3h)
-3h-10-(-2)-12h
-3h-12h-10+2
-15h-8
1. Factor P (x) = x^4 - 4x^3 + 3x^2:
1a. Factor out the GCF or x^2:
P (x) = x^2 (x^2- 4x + 3)
1b. Factor the trinomial. What multiplies to make 3 and adds to make -4?
(-1)+(-3) = -4 and (-1)(-3) = 3
P (x) = x^2 (x-1) (x-3)
2. Find the zeros be setting each factor equal to 0:
x^2 = 0 if x=0, with multiplicity 2
x-1 = 0 if x=1
x-3 = 0 if x=3
Your zeros are 0, 0, 1, and 3.
