Answer:
A. the leading coefficients of f (x) and g (x) are opposites
Step-by-step explanation:
A. the leading coefficients of f (x) and g (x) are opposites
A quadratic function in its generic form is:
f (x) = ax2 + bx + c
g (x) = dx2 + ex + f
The sum of the functions is:
(f + g) (x) = (a + d) x2 + (b + e) x + (c + f)
For the function to be linear necessarily:
a = -d
The odd natural number which is mentioned as X is 175.
<u>Step-by-step explanation:</u>
- By prime Factorization method .
- Step 1 : The prime factor for 40 is = 2×2×2×5.
- Step 2 :The prime factor for 1400 is = 2×2×2×5×5×7.
- Step 3 : the prime factor for the unknown natural odd number is to be find by comparing the factors of 40 and 1400.
- Step 4 : Lcm is known as least common multiple.
- Step 5 : Thus we can see the 5×5×7 in 1400 as different factors from the factors of 40.
- Step 6 : So lets multiply the factors we get number 175 which satisfies the condition of the odd number.
- Step 7 : The prime factors of 175 are 5×5×7.
Mercury is larger because 4,878 km vs 1736.5 x 2 = 3473 km. And since radius is half of the diameter we are multiplying by 2. So in short, Mercury is larger. Hope this helps!!!
