Find f '(−4), if f(x) = (5x2 + 6x)(3x2 + 7). Round your answer to the nearest integer.
Rzqust [24]

Use:\\(h(x)\cdot g(x))'=h'(x)g(x)+h(x)g'(x)\\\\h(x)=5x^2+6x\to h'(x)=(5x^2+6x)'=10x+6\\\\g(x)=3x^2+7\to g'(x)=(3x^2+7)'=6x\\\\f(x)=(5x^2+6x)(3x^2+7)\\\\f'(x)=(5x^2+6x)'(3x^2+7)+(5x^2+6x)(3x^2+7)'\\\\=(10x+6)(3x^2+7)+(5x^2+6x)(6x)\\\\\text{use distributive property}\\\\=30x^3+70x+18x^2+42+30x^3+36x^2\\\\=60x^3+54x^2+70x+42

\text{Put -4 instead of x into the expression}\\\\f'(-4)=60(-4)^3+54(-4)^2+70(-4)+42\\\\=60(-64)+54(16)-280+42=-3214

Henry knows that the circumference of a circle is 56.52 inches. What is the area of the circle? (Use 3.14 for x and round to the
olchik [2.2K]

Answer: 254.35ins

Step-by-step explanation:

Circumference of a circle = 2πr or πd.

Given the area of the circle = 56.52ins. To find the area of the circle, we first need to find the radius of the circle first by making r the subject of the formula.

2πr = 56. 52

r = 56.52

----------

2π

where π = 3.14

Now put this in r above and solve

r = 56.52/2 x 3.14

= 56.52/6.28

= 9ins.

Now to find the area of the circle substitute for r in the equation of the area of the circle below

Area of circle = πr²

= 3.14 x 9²

= 3.14 x 81

= 254.35ins
