P + 18 = 41
p = 41 - 18
p = 23
answer is C.
p + 18 = 41, p = 23
X + y = 39
xy = -880
x + y = 39
x - x + y = -x + 39
y = -x + 39
xy = -880
x(-x + 39) = -880
x(-x) + x(39) = -880
-x² + 39x = -880
-x² + 39x + 880 = 0
-1(x²) - 1(-39x) - 1(-880) = 0
-1(x² - 39x - 880) = 0
-1 -1
x² - 39x - 880 = 0
x² - 55x + 16x - 880 = 0
x(x) - x(55) + 16(x) - 16(55) = 0
x(x - 55) + 16(x - 55) = 0
(x + 16)(x - 55) = 0
x + 16 = 0 or x - 55 = 0
- 16 - 16 + 55 + 55
x = -16 or x = 55
x + y = 39
-16 + y = 39
+ 16 + 16
y = 55
(x, y) = (-16, 55)
or
x + y = 39
55 + y = 39
- 55 - 55
y = -16
(x, y) = (55, -16)
The two numbers that add up to 39 and multiply to -880 are 55 and -16.
A growth function is of the form
When n = 0, obtain
f(0) = a₀, which is the initial value of the function.
Answer:
f(0) represents the initial value of the growth function f(n).
Answer:
w = -8
Step-by-step explanation:
Distribute: -6 = 2w + 10
Remove the 10: -6 -10 = 2w +10 -10 ---> -16 = 2w
Isolate the variable: -16/2 = 2w/2
Answer: -8 = w
To solve this problem you must apply the proccedure shown below:
1. You must apply the formula for calculate the surface area of a cone, which is:
Where is the radius () and is the slant height () and
2. You need to substitute these values into the formula:
Therefore, the answer is the last option:
