Answer:

(f + g) x = 3 ^x + 10 x + 2 x - 4

Step-by-step explanation:

f (x) = 3^x + 10 x and g(x) = 2x - 4,

sum of f (x ) and g ( x ) =

(f + g) x = 3 ^x + 10 x + 2 x - 4

Answer:

3^x + 10x+2x-4

Step-by-step explanation:

f(x) = 3^x + 10x and g(x) = 2x - 4

(f + g)(x)= 3^x + 10x+2x-4

An airline promotion to business travelers is based on the assumption that two-thirds of business travelers use a laptop compute

skad [1K]

Answer:

The null hypothesis is $H_o : p = 0.67$

The alternative hypothesis is $H_a : p \ne 0.67$

The sample proportion is $\^ p = 0.65$

Step-by-step explanation:

From the question we are told that

The sample size is n = 546

The number of people that use a laptop overnight is $k = 355$

The population proportion is $p = \frac{2}{3} = 0.67$

Generally

The null hypothesis is $H_o : p = 0.67$

The alternative hypothesis is $H_a : p \ne 0.67$

Gnerally the sample proportion is mathematically represented as

$\^ p = \frac{ k}{n}$

=> $\^ p = \frac{ 355}{546}$

=> $\^ p = 0.65$

Use the quadratic formula to solve the equation. If necessary, round to the nearest hundredth. x2 + 3 = 9x a 0.35, -8.65 b -0.35

Tema [17]

1. You have the following quadratic equation and to solve it, you must follow the steps below:

x²+3=9x

2. The form of the equation that you need to apply the quadratic formula, is:

ax²+bx+c=0

3. Then:

x²+3=9x
 x²-9x+3=0

4. The quadratic formula is shown below:

x=(-b±√(b^2-4ac))/2a

5. Then, you have:

a=1
b=-9
c=3

6. When you substitute the values into the quadratic formula, you obtain:

x1=0.34
x2=8.65

What is the midpoint (-13,4) and (0,9)

Nadusha1986 [10]

A point serves as the midpoint of a segment if it lies on the segment and it divides the segment into two congruent segments. Other notes to. So the coordinates of B and D are 4 and 10, respectively,. and the. Because AC = 9 and CE = 9 so C divides into two. 10 + 3 = 13, so the coordinate for the other endpoint is 13.

Hope this helped
