For the function f(x)=ax^3+bx^2-5x+9, determine the values of a and b so that f(-1)=12 and f'(-1)=3

Alecsey [184]

f(x) = ax ³ + bx ² - 5x + 9

then

f '(x) = 3ax ² + 2bx - 5

Given that f (-1) = 12 and f '(-1) = 3, we get the system of equations

-a + b + 5 + 9 = 12

3a - 2b - 5 = 3

-a + b = -2

3a - 2b = 8

Multiply through the first equation by 2 and add it to the second one to eliminate b and solve for a :

2(-a + b) + (3a - 2b) = 2(-2) + 8

-2a + 2b + 3a - 2b = -4 + 8

a = 4

Substitute this into the first equation above to solve for b :

-4 + b = -2

b = 2

A rectangular prism with a length of 7 centimeters, width of 5 centimeters, and height of 8 centimeters. A rectangular prism wit

Genrish500 [490]

Answer: The volume of the composite figure is $420\text{ cm}^3$ .

Step-by-step explanation:

We know that the volume of a rectanbgular prism is given by :-

Volume = length x width x height

Given, for prism 1 , we have

length of 7 centimeters, width of 5 centimeters, and height of 8 centimeters

Volume of prism 1= $(7)(5)(8)=280\text{ cm}^3$

Given, for prism 2 , we have

length of 10 centimeters, width of 7 centimeters, and height of 4 centimeters.

Volume of prism 2= $(10)(7)(4)=280\text{ cm}^3$

Now , the volume of the composite figure = Volume of prism 1+ Volume of prism 2

$=210\text{ cm}^3+210\text{ cm}^3=420\text{ cm}^3$

Hence, the volume of the composite figure is $420\text{ cm}^3$ .

Round your answer to the tenths place!!

zysi [14]

For this case we apply the Pythagorean theorem, clearing the height we have:

$h = \sqrt {d ^ 2-w ^ 2}$

According to the data we have:

$d = 13.3 \ in\\w = 11.3 \ in$

Substituting:

$h = \sqrt {(13.3) ^ 2- (11.3) ^ 2}\\h = \sqrt {176.89-127.69}\\h = \sqrt {49.2}\\h = 7.014$

We round and we have the height is $7.0 \ in$
