Jake bakes and sell apple pies. he sells each pie for $5.75. the materials to make the pies cost $40. the boxes jake puts the pi

dezoksy [38]

Answer:

$18\ pies$

Step-by-step explanation:

Let

x-------> the number of pies

we know that

$5.75x-40-12.50=50$ -----> linear equation that represent the situation

solve for x

$5.75x-52.50=50$

$5.75x=50+52.50$

$5.75x=102.50$

$x=102.50/5.75=17.8$

Round to the nearest whole number

$17.8=18\ pies$

Answer:

$\displaystyle \int {84} \, dx = 84x + C$

General Formulas and Concepts:

Calculus

Integration

Integrals
Definite/Indefinite Integrals
Integration Constant C

Integration Rule [Reverse Power Rule]: $\displaystyle \int {x^n} \, dx = \frac{x^{n + 1}}{n + 1} + C$

Integration Property [Multiplied Constant]: $\displaystyle \int {cf(x)} \, dx = c \int {f(x)} \, dx$

Step-by-step explanation:

Step 1: Define

Identify

$\displaystyle \int {84} \, dx$

Step 2: Integrate

[Integral] Rewrite [Integration Property - Multiplied Constant]: $\displaystyle \int {84} \, dx = 84\int {} \, dx$

Suppose that the weight (in pounds) of an airplane is a linear function of the amount of fuel (in gallons) in its tank. When car

Debora [2.8K]

Step-by-step explanation:

Suppose that the weight (in pounds) of an airplane is a linear function of the amount of fuel (in gallons) in its tank. When carrying 15 gallons of fuel, the airplane weighs 2187 pounds. When carrying 35 gallons of fuel, it weighs 2303 pounds. How much does the airplane weigh if it is carrying 50 gallons of fuel?

----

You have two points relating fuel and weight.

(15,2187) and (35,2303)

------------

slope = (2303-2187)/(35-15) = 5.8

----

intercept = ?

2187 = 5.8*15 + b

b = 2100

-------

Equation:

f(x) = 5.8x + 2100

---

f(50) = 2390 lbs.
