Answer:A≈11.46
Step-by-step explanation:
9514 1404 393
Answer:
280 miles
Step-by-step explanation:
"Initial" usually refers to the value at x=0. Here, the dot is on 280 miles when x=0 days.
The initial amount of miles the car can travel is 280 miles.
Answer:
x=7/3
Step-by-step explanation:
8 ^ (x - 1 ) = 16
We need to rewrite 8 as 2^3 and 16 as 2^4
2^3 ^ (x - 1 ) = 2^4
We know that a^b^c = a^(b*c)
2^(3(x-1)) = 2^4
The bases are the same so the exponents are the same
3(x-1) = 4
Distribute
3x-3 = 4
Add 3 to each side
3x-3+3 = 4+3
3x = 7
Divide by 3
3x/3 = 7/3
x=7/3
Answer:
x < -3 or 2 < x < 7
Step-by-step explanation:
We are given that the zeroes are at
{-5, 0 , 3i}.
By the conjugate pair theorem, -3i, the conjugate of 3i, is automatically a zero for polynomials with real coefficients.
The factors of the polynomial are:
(x+5), x, (x+3i) and (x-3i)
The last two factors multiply to give a real quadratic factor of x^2+9.
Therefore the polynomial is of the form
f(x)=ax(x+5)(x^2+9)
where a is any non-zero real constant.
