Answer:

- 7

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

$\frac{f(b)-f(a)}{b-a}$

Here [ a, b ] = [ - 5, - 2 ]

f(b) = f(- 2) = (- 2)² - 4 = 4 - 4 = 0

f(a) = f(- 5) = (- 5)² - 4 = 25 - 4 = 21, thus

average rate of change = $\frac{0-21}{-2-(-5)}$ = $\frac{-21}{3}$ = - 7

What’s the volume of 4.3ft 5.2ft cone round to nearest hundredth

Vika [28.1K]

Answer:

Pick the best solution.

Step-by-step explanation:

Volume of a cone is V = ⅓πr²h

If cone diameter is 4.3

V = ⅓π(4.3/2)²(5.2) = 25.17148... ≈ 25.17 ft³

If cone radius is 4.3

V = ⅓π(4.3)²(5.2) = 100.685950... ≈ 100.69 ft³

If cone diameter is 5.2

V = ⅓π(5.2/2)²(4.3) = 30.439938... ≈ 30.44 ft³

If cone radius is 5.2

V = ⅓π(5.2)²(4.3) = 121.75975... ≈ 121.76 ft³

Write the equation in slope intercept form. what are the slope and y intercept?

VMariaS [17]

Option C

<u> Answer: </u>

The equation in slope intercept form is $-\frac{5}{12} x-\frac{11}{12}$

The slope is $-\frac{5}{12}$ and y-intercept is $-\frac{11}{12}$

<u>Solution: </u>

The slope - intercept form equation of line is given as

y = mx + c ---- eqn(1)

Where m is the slope of the line. The coefficient of “x” is the value of slope of the line.

c is the y – intercept which is the value of y at the point where the line crosses the y-axis

From question, given that -5x - 12y = 11 --- eqn (2)

On converting equation (2) in slope – intercept form, that is adding 5x on both sides,

-5x - 12y + 5x = 5x + 11

-12y = 5x + 11

Now on dividing -12 on both sides,

$y=-\frac{5}{12} x-\frac{11}{12}$ ---- eqn (3)

Comparing the given equation (3) with equation (1), we get

$m = -\frac{5}{12}$ and $c = -\frac{11}{12}$

Hence Option C is correct.

Change each phrase into an algebraic expression

maks197457 [2]

Answer:

When translating phrases into algebraic expressions, you need to identify keywords and phrases which specifically refer to a mathematical operation (addition, subtraction, multiplication, and division). Usually, you can write out the algebraic expression of the verbal description in the order that it is said
