Answer:

11^3/5

Step-by-step explanation:

Fractional exponents work like so:

x^{\frac{a}{b}} = \sqrt[b]{x^a}

Essentially, the numerator (a) of the fraction is the power and the denominator  (b) of the fraction is the root.

x^\frac{power}{root}

We are given:

\sqrt[5]{11^3}

The power is 3 and the root is 5. Let's substitute the values in.

x^\frac{power}{root}

power=3\\root=5

x^\frac{3}{5}

x is the base. In this case, the base is 11.

11^\frac{3}{5}

Therefore, 11^3/5 is the correct answer.

y-axis = altitude in feet

x-axis = minutes

slope = y/x = feet/minute


According to above data, we know that 1800 feet is y-intercept and slope is -300 feet per minute (why slope is negative? because its approaching ground at a constant speed)

a. slope = -300

  y-intercept = 1800


b. y = -300 x + 1800


c. Here we are given x = 2 minutes

y = -300(2) + 1800

y = -600 + 1800

y = 1200

The balloon will be 1200 feet high above the ground in 2 minutes.


d. Here we are given 300 feet which is y, and find x minutes.

y = -300 x + 1800

300 = -300x + 1800

300 - 1800 = - 300x

-1500 = -300x

1500 = 300 x

x = 1500 / 300

x = 5

The balloon will reach 300 feet above the ground in 5 minutes.


e. It asking when the balloon will reach the ground, if the balloon reaches the ground than the height will be 0, therefore x-intercept (y=0).

y = -300 x + 1800

0 = -300 x + 1800

-1800 = -300x

1800 / 300 = x

x = 6

The balloon will reach the ground in 6 minutes.

Step-by-step explanation:

15% of 840 is 126

30% of 840 is 252

 252

<u>+  126 </u>

<em> 378</em>

<em></em>

840 - 378 = <em>462</em>

or

Answer:

First we find the value of x,

x ≥ -4

Step-by-step explanation:

3x+7 ≥ -5

3x ≥ -5 -7

3x ≥ -12

x ≥ -4

Now to graph this inequality, consider number line.

numbers greater than and equal to -4 are -3,-2,-1,0 and so on.

Note that in solution -4 is included so in graphing we use dot (filled circle).
