Answer: y = 9
Step-by-step explanation:
x = 8 * 3 = 24
y = 3 * 3 = 9
so when x = 8 and y = 3, y = 9 when x = 24
Answer:
last option at the bottom.
Step-by-step explanation:
we are told that the the equation
y = 0.73x + 1 represents the Length of the spring when a stretch force is applied,
basically y = length of spring and x = force applied.
from the graph, we can see that when stretch force = 0 (i.e x = 0)
the equation becomes y = 1.
That is to say that the spring has a length of 1 inch when stretch force is zero
(which basically is the same as the last option)
f(x) = x^3 + 5x^2 - 4x - 20
The zeros of the polynomial function: x^3 + 5x^2 - 4x - 20 = 0
x^3 + 5x^2 - 4x - 20 = 0
x^2(x + 5) - 4(x + 5) = 0
(x^2 - 4)(x + 5) = 0
(x + 2)(x - 2)(x + 5) = 0
(x + 2) = 0; x = -2
(x - 2) = 0; x = 2
(x + 5) = 0; x = -5
Answer is the first one
x = -5, x = -2, x = 2
I have to assume that the 24, the 72, and the 18 are feet.
If those are the dimensions of a rectangular prism, like a box, a crate,
or a humongous block of ice, then
Volume = (length) x (width) x (height) =
(24-ft) x (72-ft) x (18-ft) = <em>31,104 cubic ft</em>
If those numbers are <u>inches</u>, then here's the easy way to handle it:
24 inches = 2 ft
72 inches = 6 ft
18 inches = 1.5 ft
Volume = (length) x (width) x (height) =
(2ft) x (6ft) x (1.5ft) = <em>18 cubic feet
</em>
