The second derivative of a function hhh is given by h''(x)=\dfrac{\sqrt[3]{x}}{e^x}+1h ′′ (x)= e x 3 x ​ ​ +1h, start superscript, prime, prime, end superscript, left parenthesis, x, right parenthesis, equals, start fraction, cube root of, x, end cube root, divided by, e, start superscript, x, end superscript, end fraction, plus, 1. Where does the graph of hhh have a point of inflection?

idk

step-by-step explanation:

i don't know

answer: its the third option.

step-by-step explanation:

i just took the test.

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
