2/9 = x/243

9x = 2 * 243

x = 54

Barbara have after the 30 weeks?
$684

Use a definite integral to find the area under the curve between the given x-values. f(x) = 3 x from x = 1 to x = 8

Answers

Answer: 94.5

Step-by-step explanation:

Given

Function is [tex]f(x)=3x[/tex] and the boundary is [tex]x=1\ \text{to}\ x=8[/tex]

Integrating the function

[tex]\Rightarrow I=\int_{1}^{8}f(x)dx\\\\\Rightarrow I=\int_{1}^{8}3xdx\\\\\Rightarrow I=\left ( \frac{3x^2}{2} \right )_1^8\\\Rightarrow I=1.5(8^2-1^2)=1.5(64-1)\\\Rightarrow I=94.5[/tex]

The value of integral is 94.5
