Answer:

x^4 and 4

Step-by-step explanation:

The formula for finding the derivative of a function includes the following:

f(a+h) - f(a)

and in this case we have

f(4+h) - f(4) => f(4 + h)^4 - 4^4.

Comparing this to

f(a + h) - f(a), we see that a must be 4 and f(x) must be x^4.

Which equation represents the line that passes through (–6, 7) and (–3, 6)?

ipn [44]

Answer:

$y = \frac{-x}{3} + 5$

Step-by-step explanation:

Given A (x₁, y₁) = ( -6, 7) and B (x₂, y₂) = (-3, 6)

Slope of line passing through points ( -6, 7) and (-3, 6) is:

m = $\frac{y_{2} -y_{1}}{x_{2} -x_{1}} =\frac{6 - 7}{-3 + 6} =\frac{-1}{3}$

Now, the equation of line in point-slope form:

(y - y₁) = m (x - x₁)

Substituting the value of m and (x₁, y₁) = ( -6, 7) in above equation,

$(y - 7) = \frac{-1}{3}(x - (-6))$

$(y - 7) = \frac{-1}{3}(x + 6)$

$3y - 21 = -x - 6$

$3y = -x - 6 + 21$

$3y = -x + 15$

$y = \frac{-x + 15}{3}$

$y = \frac{-x}{3} + 5$

Option B is the correct answer.

25 POINTS I WILL GIVE BRAINLIEST

Nutka1998 [239]

Answer:

$10.01

where x = 4.1/10 x=14.11

Step-by-step explanation:

-7x^2 + 32x + 240

-7x^2 +32x

-49x+32 +240

240/17x = 17/240

240/49x = 4 9/10

x = 14.11 - 4. 10 9/10

x = -4.01

rounded to 2dp

x = 14.11

x = -4.01
