Answer:

The value of c is 5 units.

Step-by-step explanation:

Now by using the pythagorean theorem

Hypotenuse² = Perpendicular² + Base²

As in Δ WYZ.

WZ² = ZY² + WY²

Hypotenuse = WZ = c

Perpendicular = WY = 4 units

Base = ZY = 3 units

Put in the above

c² = 4² + 3²

c² = 16 + 9

c² = 25

$c = \sqrt{25}$

c = 5 units

Therefore the value of c is 5 units.

HALP Can someone explain why this is a math question

erica [24]

Answer:

If the robot has more mass, then it will take a bigger force to lift up another object. If the robot is going to lift something up, it will use its arms, and its arms have mass, and the object has a mass as well. If the robot's arms have a mass of 10kg, and the object has a mass of 12kg, it will use a certain amount of force to lift up the object using it's arms. If the the robots arms were 5kg instead, it would take less force to lift of the same object using its arms.

Assignment: Translating Functions Investigation

Leto [7]

Answer:

Part A)

1) The graph in the attached figure N 1

2) The coordinate rule is (x,y) -----> (x,y+10)

3) The translation of the function up 10 units means that the initial deposit is $60 instead of $50

Part B)

1) The graph in the attached figure N2

2) The coordinate rule is (x,y) -----> (x-10,y)

3) The translation of the function right 10 units means that the initial deposit is equal to $10

Part C)

1) In each translation, the slope is the same (m=5) are parallel lines

2) The vertical translation would be up 40 units

Step-by-step explanation:

we have

$f(x)=5x+50$

where

f(x) --> represents Jeremy's account balance

x ---> the time in years

Part A)

The translation of the function is up 10 units.

The rule of the translation is equal to

(x,y) -----> (x,y+10)

The new function will be

$f(x)=5x+50+10$

$f(x)=5x+60$

The graph in the attached figure N 1

The translation of the function up 10 units means that the initial deposit is $60 instead of $50

Part B)

The translation of the function is right 10 units.

The rule of the translation is equal to

(x,y) -----> (x-10,y)

we have

$f(x)=5x+60$ ----> function Part A

The new function will be

$f(x)=5(x-10)+60$

$f(x)=5x+10$

The graph in the attached figure N 2

The translation of the function right 10 units means that the initial deposit is equal to $10

Part C)

1. Look at the translations, what characteristic of the graph stayed the same in each translation?

In each translation, the slope is the same

The slope m is equal to m=5

Are parallel lines

2. Look at the original graph and the graph of the translation right 10 units. What vertical translation of the graph in Part B would put the graph back to its original position?

we have

$f(x)=5x+10$

The vertical translation would be up 40 units

The rule of the translation is equal to

(x,y) -----> (x,y+40)

The new function will be

$f(x)=5x+10+40$

$f(x)=5x+50$

A 10-foot ladder is leaning against a vertical wall. If the bottom of the ladder is being pulled away from the wall at the rate

Alex777 [14]

Answer:

The area is changing at 15.75 square feet per second.

Step-by-step explanation:

The triangle between the wall, the ground, and the ladder has the following dimensions:

H: is the length of the ladder (hypotenuse) = 10 ft

B: is the distance between the wall and the ladder (base) = 6 ft

L: the length of the wall (height of the triangle) =?

dB/dt = is the variation of the base of the triangle = 9 ft/s

First, we need to find the other side of the triangle:

$H^{2} = B^{2} + L^{2}$

$L = \sqrt{H^{2} - B^{2}} = \sqrt{(10)^{2} - B^{2}} = \sqrt{100 - B^{2}}$

Now, the area (A) of the triangle is:

$A = \frac{BL}{2}$

Hence, the rate of change of the area is given by:

$\frac{dA}{dt} = \frac{1}{2}[L*\frac{dB}{dt} + B\frac{dL}{dt}]$

$\frac{dA}{dt} = \frac{1}{2}[\sqrt{100 - B^{2}}*\frac{dB}{dt} + B\frac{d(\sqrt{100 - B^{2}})}{dt}]$

$\frac{dA}{dt} = \frac{1}{2}[\sqrt{100 - B^{2}}*\frac{dB}{dt} - \frac{B^{2}}{(\sqrt{100 - B^{2}})}*\frac{dB}{dt}]$

$\frac{dA}{dt} = \frac{1}{2}[\sqrt{100 - 6^{2}}*9 - \frac{6^{2}}{\sqrt{100 - 6^{2}}}*9]$

$\frac{dA}{dt} = 15.75 ft^{2}/s$

Therefore, the area is changing at 15.75 square feet per second.

I hope it helps you!

A function assigns the values. The force that will be required to move the rock is 48 lbs.

<h3>What is a Function?</h3>

A function assigns the value of each element of one set to the other specific element of another set.

A.) The inverse of the function f(x)=1/x is,

f(x) = 1/x

y = 1/x

x = 1/y

g(x)=1/x

Hence, The inverse of the function f(x)=1/x is g(x)=1/x.

B.) The force that will be required to move the rock using the momentum,

9ft × 80lbs = 15 ft × F

F = 48 lbs

Hence, The force that will be required to move the rock is 48 lbs.
