In baseball, the equation E = 9RI gives a pitcher's earned run average, E where R is the number of earned runs the player is all

kondor19780726 [428]

Answer:

I = $\frac{E}{9R}$

Step-by-step explanation:

Given

E = 9RI ( isolate I by dividing both sides by 9R )

$\frac{E}{9R}$ = I

Give an example of a function F(x) that is an antiderivative of f(x) = 9 cos(9x)+ 3x^2

liubo4ka [24]

We are integrating f(x) = 9cos(9x) + 3x²: $\int\ {9cos(9x)+3x^{2} } \, dx$

a) Apply the sum rule

$\int\9cos(9x)} \, dx +\int\ 3x^{2} } \, dx$

b) Calculate each antiderivative

<u>First integral</u>

$\int\ {9cos(9x)} \, dx$

1. Take out the constant

$9\int\ {cos(9x)} \, dx$

2. Apply u-substitution, where u is 9x

$9\int\ {cos(u)\frac{1}{9} } du$

3. Take out the constant (again)

$9*\frac{1}{9} \int{cos(u)} du$

4. Take the common integral of cos, which is sin

$9*\frac{1}{9}sin(u)}$

5. Substitute the original function back in for u and simplify $9*\frac{1}{9} sin(9x) = sin(9x)$

6. Always remember to add an arbitrary constant, C, at the end

$sin(9x) + C$

<u>Second integral</u>

$\int3x^{2} } \, dx$

1. Take out the constant

$3\int{x^{2} } \, dx$

2. Apply the power rule, $\int{x}^{a} \, dx =\frac{x^{a+1} }{a+1}$ , where <em>a</em> is your exponent

⇒ $3*\frac{x^{2+1} }{2+1} = x^{3}$

3. Add the arbitrary constant

$x^{3} + C$

c) Add the integrals

sin(9x) + C + x³ + C = sin(9x) + x³ + C

Notice the two arbitrary constants. Since we do not know what either constant is, we can combine them into one arbitrary constant.

<h3>Answer:</h3>

F(x) = sin(9x) + x³ + C

Jeremy is cutting a board into pieces that are 1 2/3 feet long . The board is 14 1/4 feet long . How many 1 2/3 -feet long piece

Solnce55 [7]

Answer:

Total number of 1 2/3 feet long pieces that will be cut=8 pieces

Step-by-step explanation:

This can be expressed as;

Total length of the board=length per piece×number of pieces

where;

Total length of board=14 1/4 feet

Length per piece=1 2/3 feet

Number of pieces=n

Replacing;

14 1/4=1 2/3×n

(57/4)=(5/3)n

n=(57/4)×(3/5)=8.55

Total number of 1 2/3 feet long pieces that will be cut=8 pieces
