Why is he wrong? What is the correct answer?

the only one i can think of at the moment in pinterest

Step-by-step explanation:

sorry thats all i can think of

Using ratio and proportion, the answer is: 78.3J.

The workdone of the object  with the object's displacement of 56 degree and  force of 140 J is 78.23 J.

Workdone can be explained as the product of the force that is exerted and the distance that is covered.

Given, displacement angle as 56 degree

force of  140 J

Then, work done by a force on a moving object,  the equation can be used in calculation of the workdone

W =( F * d * cos(Ф ))

Then if we input our values we,

W = (140 J) * cos(56°)

W = 78.23 J

Therefore ,  workdone of the object  with the object's displacement of 56 degree and  force of 140 J is 78.23 J.

Answer:

y=5x-10

Step-by-step explanation:

To find the slope

rise/run

10-5=5

4-3=1

The slope is 5

Y-intercept

y=5x+b

Use any coordinate for y and x and solve

10=5(4) +b

10=20+b

-10=b

-10 id the y-intercept

Answer:

[tex]\frac{3}{8}[/tex]

Step-by-step explanation:

[tex]A=6*\frac{1}{4} ^2\\\\A=6*\frac{1}{16} \\\\A=\frac{6}{16} \\\\A=\frac{3}{8}[/tex]

Answer:

[tex]A = \frac{3}{8}ft^2[/tex]

Step-by-step explanation:

Using the given formula, [tex]A=6s^2[/tex], and the given value for the side length of the cube, [tex]\frac{1}{4}[/tex] foot, substitute the given value into the equation and solve.

[tex]A=6(\frac{1}{4})^2[/tex]

Remember, setting any value to the second power is the same as multiplying the base (the value that is being squared) by itself. Apply this information to the given problem,

[tex]A = 6(\frac{1}{4}*\frac{1}{4})\\\\A = 6(\frac{1}{16})\\\\A = \frac{6}{16}\\\\A = \frac{3}{8}[/tex]

Step-by-step explanation:

Given

Coordinates of Old oak tree are (3,7)

Coordinates of granite boulder are (-2,6)

Distance between them is given by distance formula i.e.

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Distance between them is

[tex]\Rightarrow d=\sqrt{(-2-3)^2+(6-7)^2}\\\Rightarrow d=\sqrt{(-5)^2+(-1)^2}\\\Rightarrow d=\sqrt{25+1}=\sqrt{26}\approx 5.09\ \text{units}[/tex]

This is a tricky problem, don't feel bad for not knowing this  :/  I think this is too much in one question even :P  I'll give you the answers and how to get them but really it's going to be a lot to understand in one try.  Pay attention :P

Step-by-step explanation:

first graph the given table .. I use Desmos b/c it's handy

we want y = A[tex]x^{2}[/tex] + bx + c

given   1st      2nd

5          -5          2

0         -3           2

-3        -1           2

-4        1           2

-3        3          2

0         5          2

5          7        

12        

A=2nd / 2  = 2/2 = 1

B=?

C= 5

x=1

y=12

y = a[tex]x^{2}[/tex] + bx +c

12=[tex]1^{2}[/tex] + b(1) +5

12=1+ b +5

6=b   :)

y = [tex]x^{2}[/tex] + 6x +5       ( the answer to a) in the question )  

factor it

(x+5)(x+1)   ( answer to b) in the question

vertex form

y = a(x-h)2 + k

where  h = −b/2a

and k = f( h )

h=6/2(1) = 3

k = [tex]3^{2}[/tex] + 6(3) +5

k=32

y =x-3 + 32  ( answer to c)   in question )

let me know if this worked for you  :)  ( I did this fast late at night :/ )

Step-by-step explanation:

Answer:

10e + 3 < 92

Step-by-step explanation:

Any number times ten plus three is less than 92. Like e = 3, which would be 10(3)+3, or 33. Any number that would make the statement true can be used in the place of e.

Answer:

5.1 years

Step-by-step explanation:

the formula for fixed rate depreciation is

Value after t years = initial value ( 1 - r )^t

where r = depreciation rate = 6.25% = 0.0625

t = length of time in years (we are asked to find this

Value after t years = given as $11,500

initial Value = given as $16,000

Substituting this into equation

11,500 = 16,000 (1 - 0.0625) ^t

11,500 = 16,000 (0.9375) ^t  (divide both sides by 16,000 and rearrange)

0.9375^t = 11,500 / 16000

0.9375^t = 0.71875  (taking log of both sides)

t log 0.9375 = log 0.71875

t =   log 0.71875 / log 0.9375  (use calculator)

t = 5.12

t = 5.1 years (nearest tenth)
