Consider the function g(x)=5x2−18x+35. find the area under the curve g(x) from x = 0 to x = 13 and then subtract from it the are
Black_prince [1.1K]
We integrate the given equation such that,

    integral of g(x) = (5/3)x³ - 9x² + 35x

Substituting,
   x = 13
    integral of g(x) = (5/3)(13³) - 9(13)² + 35(13) 
                  = 2595.67

and,   x = 0
   integral of g(x) = 0
  
 The area is 2595.67 - 0 = 2595.67

For the second part,
   x = 1
  integral of g(x) = (5/3)(1)³  - 9(1)² + 35(1)  
             = 27.67

Area under the curve between x = 0 and x = 1 is 27.67


The difference between the two areas is,
    2595.67 - 27.67 = 2568.0

Answer: 2568.0 units squared

Find the value of x so that (x, 12) satisfies y = 4x +4.
Elena L [17]
Plug in 12 for y and rewrite the equation.

12 = 4x + 4

Subtract 4 from both sides.

8 = 4x

Divide by 4 on both sides.

2 = x

The ordered pair is (2, 12) and x = 2.

The point (3,0) lies on a circle with the center at the origin. What is the area of the circle to the nearest hundredth?
juin [17]

we know that

the equation of a circle with the center at the origin is equal to

x^{2} +y^{2} =r^{2}


step 1

with the point (3,0) find the value of the radius

substitute the values of

x=3\\ y=0

in the equation of the circle above

so

3^{2} +0^{2} =r^{2}

3^{2} =r^{2}

r =3


step 2

with the radius find the area of the circle

area of the circle is equal to

A=\pi *r^{2}

for r=3

A=\pi *3^{2}

A=28.27units²

therefore


the answer is

the area of the circle to the nearest hundredth is A=28.27units²
