Step-by-step explanation:
Combine common terms
(3x²+5x²)+(7x-4x)+(-5+11)
8x²+3x+6
Answer:
<u>The function is:</u>
<u>According to data in the table we have:</u>
- f(1) = 3 ⇒ a(1)ⁿ = 3 ⇒ a*1 = 3 ⇒ a = 3
- f(2) = 12 ⇒ 3*2ⁿ = 12 ⇒ 2ⁿ = 4 ⇒ n = 2
<u>Since we found the values of a and n, the function becomes:</u>
<u>The number of infected to the tenth day:</u>
A common tangent is a line that happens to be tangent ("touching but not intersecting a curve or curved surface") to two different coplanar ("in the same plane) circles. I do hope that helped you.
Hello :
the system of equations can be used to find the roots of the equation 12x^3-5x=2x^2+x+6 is : y = 12x^3-5x
y = 2x^2+x+6
Answer:
5
Step-by-step explanation:
f(-4) = sqrt(2(4)^2 -7) (Plug in -4)
f(-4)= sqrt(2(16)-7) (Square 4 which is 16)
f(-4)=sqrt(32-7) (Multiply by 2)
f(-4)=sqrt(25) (Subtract 7)
f(-4)=+/- 5 (take the square root of 25 which is postive/negative 5)
Since this is a function there can only be one y to an x the positive 5 is the only answer
