Using the graph below, calculate the average rate of change for f(x) from
Annette [7]

Answer:

4

Step-by-step explanation:

Average rate of change = \frac{f(b) - f(a)}{b - a}

Where,

a = 0,

f(a) = f(0) = -2 (from the graph given)

b = 2,

f(b) = f(2) = 5 (from the graph)

Plug in the values

Average rate of change = \frac{5 - (-2)}{2 - 0}

= \frac{7}{2}

= 3.5 ≈ 4 (approximated)

Hey ok i need help on this question ive been stuck on it for a couple minutes haha
Len [333]

Answer:

The side s has a length of 4 and side q has a length of 4\sqrt{3} ⇒ F

Step-by-step explanation:

In the 30°-60°-90° triangle, there is a ratio between its sides

side opp (30°) : side opp (60°) : hypotenuse

       1               :         \sqrt{3}            :        2

In the given triangle

∵ The side opposite to 30° is s

∵ The side opposite to 60° is q

∵ The hypotenuse is 8

→ Use the ratio above to find the lengths of s and q

side opp (30°) : side opp (60°) : hypotenuse

       1               :         \sqrt{3}            :        2

       s               :          q             :        8

→ By using cross multiplication

∵ s × 2 = 1 × 8

∴ 2s = 8

→ Divide both sides by 2

∴ s = 4

∴ The length of s is 4

∵ q × 2 = \sqrt{3} × 8

∴ 2q = 8\sqrt{3}

→ Divide both sides by 2

∴ q = 4\sqrt{3}

∴ The length of q is 4\sqrt{3}

Suppose 6 is a factor of ab, where a and b are natural numbers. Make a valid argument to explain why each assertion is true or p
Afina-wow [57]
Example
if ab=6
and a=3
b=2

a. 6 must be factor of 3 or 2 FALSE
b. 3 must be a factor of 3 OR 2 TRUE
c. 3 must be a factor of 3 AND 2 FALSE



B is true

How do i solve this equation: 4/5a + 3 = 1/3a - 8
DENIUS [597]
You have to subtract by \frac{1}{3}a on EACH of  the sides you're working with!

\frac{4}{5}a + 3 - \frac{1}{3}a - 8 - \frac{1}{3}a

Which gives us: \frac{7}{15}a + 3 = -8

Now, that we got these steps out of the way, let's subtract 3 from the sides you're working with! 

\frac{7}{15}a  + 3 - 3 \\ = -8 -3

 \frac{7}{15}(a) = -11

We have gotten these  steps out of the way now lets multiply by \frac{15}{7} on your sides because, it is the reciprocal of \frac{7}{15}

So,  \frac{15}{7}( \frac{7}{15}a ) =  \frac{15}{7}  (-11)

Cancel out: \frac{15}{7}( \frac{7}{15} ) because, it equals to:1

\frac{15}{7}(-11) =   \frac{-165}{7}

Therefore, your answer is:  \frac{-165}{7} aka 23\frac{4}{7} 

Good luck on your assignment and enjoy your day
