How does a airplane fly?

1 answer:

4 0

A plane's engines are designed to move it forward at high speed. That makes air flow rapidly over the wings, which throw the air down toward the ground, generating an upward force called lift that overcomes the plane's weight and holds it in the sky. ... The wings force the air downward and that pushes the plane upward.

Given limit f(x) = 4 as x approaches 0. What is limit 1/4[f(x)]^4 as x approaches 0?

stepladder [879]

Answer:

$\displaystyle 64$

General Formulas and Concepts:

Calculus

Limits

Limit Rule [Variable Direct Substitution]: $\displaystyle \lim_{x \to c} x = c$

Limit Rule [Variable Direct Substitution Exponential]: $\displaystyle \lim_{x \to c} x^n = c^n$

Limit Property [Multiplied Constant]: $\displaystyle \lim_{x \to c} bf(x) = b \lim_{x \to c} f(x)$

Step-by-step explanation:

Step 1: Define

Identify

$\displaystyle \lim_{x \to 0} f(x) = 4$

Step 2: Solve

Rewrite [Limit Property - Multiplied Constant]: $\displaystyle \lim_{x \to 0} \frac{1}{4}[f(x)]^4 = \frac{1}{4} \lim_{x \to 0} [f(x)]^4$
Evaluate limit [Limit Rule - Variable Direct Substitution Exponential]: $\displaystyle \lim_{x \to 0} \frac{1}{4}[f(x)]^4 = \frac{1}{4}(4^4)$
Simplify: $\displaystyle \lim_{x \to 0} \frac{1}{4}[f(x)]^4 = 64$

Please help! THE QUESTION IS IN THE PIC!

Kruka [31]

Answer:

-11 x + 19 thus c.) is your answer

Step-by-step explanation:

Simplify the following:

-5 + 4 (6 - 2 x) - 3 x

4 (6 - 2 x) = 24 - 8 x:

-3 x + 24 - 8 x - 5

Add like terms. 24 - 5 = 19:

-3 x - 8 x + 19

-8 x - 3 x = -11 x:

Answer: -11 x + 19

Please help me find the values of these irraational numbers on a number line!!!

uranmaximum [27]

Here, You have to simplify every number to their simple form and place it on the arrow by approximation:

So, Here is your answers:

Upper Arrows (From Left towards right):
1st = -10√2/3
2nd = -√7
3rd = ∛4
4th = √50

Lower Arrows (From Left towards right):
1st = -√99
2nd = -√17
3rd = ∛9
4th = π

Hope this helps!
