A soda machine takes 3 seconds to fill a 15-ounce cup. If t represents the time in seconds, which equation can you use to find h
Svet_ta [14]

Information we know:

a 15 ounce cup takes 3 second to fill

determine variables:

x=3

y=15

rate:

y/x=3/15= 0.2

fixture an equation:

y=kx

y=0.2x

plug in 40 for x:

y=0.2(40)

=8

Thus, it should take 8 seconds to fill a 40-ounce cup of soda.

Can someone please help me with this multiple choice question?
iVinArrow [24]
1) the small and large triangles are similar, then we can write:

x/24 = 8/18
Cross multiplication → 18x = 24.8 → 18x = 192 and x = 192/18

and x = 32/3 Or 10 ²/³

2) Δ ABC is similar to Δ EDC Since:

∠A = ∠D = 90°

∠C is common

Use the Fundamental Theorem of Calculus to find the "area under curve" of
lozanna [386]

Answer:

\displaystyle A = 300

General Formulas and Concepts:

<u>Calculus</u>

Integrals

  • Definite Integrals
  • Area under the curve
  • Integration Constant C

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

Integration Rule [Fundamental Theorem of Calculus 1]:                                        \displaystyle \int\limits^b_a {f(x)} \, dx = F(b) - F(a)

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

Integration Property [Addition/Subtraction]:                                                           \displaystyle \int {[f(x) \pm g(x)]} \, dx = \int {f(x)} \, dx \pm \int {g(x)} \, dx

Area of a Region Formula:                                                                                       \displaystyle A = \int\limits^b_a {[f(x) - g(x)]} \, dx

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

f(x) = 6x + 19

Interval [12, 15]

<u>Step 2: Find Area</u>

  1. Substitute in variables [Area of a Region Formula]:                                       \displaystyle A = \int\limits^{15}_{12} {(6x + 19)} \, dx
  2. [Integral] Rewrite [Integration Property - Addition/Subtraction]:                   \displaystyle A = \int\limits^{15}_{12} {6x} \, dx + \int\limits^{15}_{12} {19} \, dx
  3. [Integrals] Rewrite [Integration Property - Multiplied Constant]:                   \displaystyle A = 6\int\limits^{15}_{12} {x} \, dx + 19\int\limits^{15}_{12} {} \, dx
  4. [Integrals] Integrate [Integration Rule - Reverse Power Rule]:                      \displaystyle A = 6(\frac{x^2}{2}) \bigg| \limits^{15}_{12} + 19(x) \bigg| \limits^{15}_{12}
  5. Evaluate [Integration Rule - Fundamental Theorem of Calculus 1]:              \displaystyle A = 6(\frac{81}{2}) + 19(3)
  6. Simplify:                                                                                                             \displaystyle A = 300
