Answer:

f(x) = x^3 + 4x^2 - 7x - 28

Step-by-step explanation:

If the roots of this cubic function are Square root of seven,  -Square root of seven,  -4, then the factors must be (x^2 - 7)(x + 4).

Multiplying this out, we get f(x) = x^3 + 4x^2 - 7x - 28.

Note:  Please use " ^ " to indicate exponentiation.

Which expressions are equivalent to 4m + 12? Choose ALL that apply.<br>​
riadik2000 [5.3K]

Answer:

Step-by-step explanation:

Option 1:

4(m + 12) = 4m + 48 (not what we want)

Option 2:

6m - 2m + 12 = 4m + 12 (one of the right answers)

Option 3:

4(m + 3) = 4m + 12 (one of the right answers)

Option 4:

3m - m + 12 = 2m + 12 (not what we want)

Therefore the correct answers are Option 2 and Option 3.

What is the sum of (–6) + (–6) + (–6) + (–6) + (–6) + (–6)
nalin [4]

It looks like you've got six numbers lined up there, every one of them is the same number, and you need to have them added up.

Well, you've got (-6) listed six ==> <em>TIMES</em> <== , so the situation is the same as if you just wrote

6 x (-6)

and that's just <em>-36 </em>.

SpyIntel [72]

Answer:

g(f(d)) = -dlog_{10}(0.5 * 10^{-4})

Step-by-step explanation:

Given

f(d) = (0.5 * 10^{-4})^d

g(H+) = -log_{10}(H+)

Required

Find the composite function g(f(d))

We have:

g(H+) = -log_{10}(H+)

Substitute f(d) for H+

g(f(d)) = -log_{10}(f(d))

Substitute f(d) = (0.5 * 10^{-4})^d

g(f(d)) = -log_{10}((0.5 * 10^{-4})^d)

Apply law of logarithm

g(f(d)) = -dlog_{10}(0.5 * 10^{-4})

Hence, the function is:

g(f(d)) = -dlog_{10}(0.5 * 10^{-4})
