Answer:

To find the second-shortest side we'll multiply 9 by √3 which is 9√3 and for the hypotenuse we'll do 9 * 2 = 18.

Evaluate the function for an input value of 3. f (x) = -4x^2 – 3x – 5

Lina20 [59]

Answer:

Step-by-step explanation:

Function given:

f(x) = -4x² – 3x – 5

Evaluate the function for an input value of 3

Input value is x = 3, output value is:

f(3) = -4(3²) – 3(3) – 5 = -4(9) - 9 - 5 = -36 - 14 = -50
f(3) = -50

Suppose an isosceles triangle abc has a=pi/4 and b=c=4. What is the length of a^2?

Zanzabum

The law of cosines states that, if $\alpha$ is the angle between sides b and c,

$a^2 = b^2+c^2-2bc\cos(\alpha)$

So, plugging our values, we have

$a^2 = 16+16-2\cdot 4\cdot 4\cdot\cos\left(\dfrac{\pi}{4}\right)$

This is equal to

$a^2 = 32-32\cdot\dfrac{\sqrt{2}}{2} = 32-16\sqrt{2}$

The volume of a room that is 23 feet in W , 10 feet in D, and 8 feet in H is?

Solnce55 [7]

The volume of the room is: 1840 ft^3

Step-by-step explanation:

The volume is the capacity of a given figure.

Given

Width = w = 23 feet

Depth = d = 10 feet

Height = h = 8 feet

The formula for volume is:

$V = W*D*H\\= 23*10*8\\=1840\ ft^3$

The volume of the room is: 1840 ft^3
