Answer:
(3,0), (4,0), (5,0)
on the x-axis at 3, 4 and 5
Step-by-step explanation:
This function is a lovely swoopey cubic curve. If we finish factoring it, it's not to hard to see the x-intercepts. You set it equal to zero and solve it. The solutions are the x-intercepts (are the "zeros")
0=(x-5)(x^2-7x+12)
0=(x-5)(x-3)(x-4)
0=x-5, 0=x-3 & 0=x-4
x=5, x=3, x=4
This is where the graph crosses the x-axis.
Answer:
When added together, the sum of the given functions have a value of -6.
Step-by-step explanation:
When we see f(-2), it means that our value of x for the f(x) function is -2. When we see g(5), it means that our value of x for the g(x) function is 5. So, let's use this information and plug it into our equation.
f(-2) + f(5) = (3(-2) - 1) + (-(5) + 6)
Multiply 3 by -2 and distribute the negative to 5.
f(-2) + f(5) = (-6 - 1) + (-5 + 6)
Subtract 1 from -6 and add 6 to -5.
f(-2) + f(5) = (-7) + (1)
Add 1 to -7.
f(-2) + f(5) = -6
So, when added, the sum of the functions is -6.
Answer:
14 ounce bottle
Step-by-step explanation:
I just got the answer right :)
57 cm^2 is equal to the lateral surface area, or the three sides in this case.
57/3= 19 cm^2 per side. Because the base is equal to the area of the side, this is the base area.
19+57= 76 cm^2 for sides+ base (total surface area)
Final answer: 76 cm^2
