F(x)=x 2 +10f, left parenthesis, x, right parenthesis, equals, x, squared, plus, 10 What is the average rate of change of fff ov

pav-90 [236]

Answer:

Average rate of change=-3

Step-by-step explanation:

The average rate of change is given by the relation between the values of f(x) and x, in two different points as follows:

$Change=\frac{f(x_{2})- f(x_{1})}{x_2-x_1}$

In this case, $x_{1}=-2; x_{2}=-1$

Therefore,

$Change=\frac{((-1)^{2}+10) -((-2)^{2}+10)}{-1-(-2)}=\frac{11-14}{1}=-3$

Write the sum in standard form B) f(x)-h(x)

VLD [36.1K]

Answer:

Step-by-step explanation:

f(x) -h(x) = x³ + 2x² -7x - 8 - [4x² - x - 15 ]

= x³ + 2x² - 7x - 8 - 4x² + x + 15

= x³ + 2x² - 4x² - 7x + x - 8 + 15

= x³ - 2x² - 6x + 7

I need help with the first questions!!

solniwko [45]

Answer:

Step-by-step explanation:

Difference between (x) & (x')

P - P' = (2 - (-6) , 2 - 2) = (-8,0)

Q - Q' = (5 - (-3), 2 - 2) = (-8,0)

etc...

Always get (-8,0) hence -8 in x-direction

The brain volumes (cm cubed) of 20 brains have a mean of 1162.8 cm cubed and a standard deviation of 127.1 cm cubed. Use the g

Free_Kalibri [48]

Answer:

- The limits are 908.6 cm^3 and 1417cm^3

- 1337.0cm^3 is in between the limits

Step-by-step explanation:

To determine the limit by taking into account the range rule of thumb, you use the fact that the limits are given by the mean plus and minus twice the standard deviation, that is:

$\overline{x}\pm 2\sigma$ (1)

$\overline{x}$ : mean of brain volume = 1162.8 cm^3

σ: standard deviation = 127.1 cm^3

You replace the values of the parameters in the equation (1):

$1162.8cm^3+2(127.1cm^3)=1417cm^3\\\\1162.8cm^3-2(127.1cm^3)=908.6cm^3$

Limits = (1417 , 908.6)

The limits are 908.6 cm^3 and 1417cm^3

1337.0cm^3 is in between the limits calculated above.

Is the area of this 36 (2, 8), (2, 2), (–4, 2), and (–4, 8).

almond37 [142]

Answer:

yes

Step-by-step explanation:

side 1

(2,8) to (2,2)

8-2 = 6 (length of this side)

side 2

(2,2) to (-4,2)

2-(-4) = 6

side 3

(-4,2) to (-4,8)

8-2 = 6

side 4

(-4,8) to (2,8)

2- (-4) = 6

* note: it doesn't matter the order of subtraction because length can't be negative (so just make sure your answer is positive) , also don't subtract the side that is constant, you will get 0, a side can not be 0 cm

to find the area of a square multiply length by width

6 x 6 = 36
