Jin has 34 feet of garden fence. He wants the shape of his garden to be a rectangle 5 feet wide.
Which should be the length of Jin's garden?
O A 42 feet
OB 24 feet
O c. 12 feet
D. 6 feet

Answers

C) 12 feet
Form equation 34=2x+10 (2 unknown lengths which are x and two 5 feet widths. They add up to his 34 feet of fence total).
Subtract 10 from both sides to whet 24=2x.
Divide both sides by 2 to isolate x and get the length is 12 feet.

E varies directly with G. When G is 6, E is 10. Find the value of G when E is 18.

Answers

Answer:

  10.8

Step-by-step explanation:

E has increased by a factor of 18/10 = 1.8, so G will increase by that factor. The corresponding value of G is ...

  6 × 1.8 = 10.8 = G

__

If you like, you can write an equation relating G to E:

  E = kG

  10 = k(6)

  k = 10/6 = 5/3

Now for E = 18, we have ...

  18 = (5/3)G

  18(3/5) = G = 10.8

Solve the equation 3(m + 5) = 3 + 3(2m + 2) for m.

Answers

Answer:

m=2

Step-by-step explanation:

Answer:

[tex]m=2[/tex]

Step-by-step explanation:

[tex]3\left(m+5\right)=3+3\left(2m+2\right)[/tex]

Expand:

[tex]3m+3\times5=3+3\times2m+3\times2[/tex]

[tex]3m+15=3+6m+6[/tex]

[tex]3m+15=6m+9[/tex]

Subtract 15 from both sides:

[tex]3m+15-15=6m+9-15[/tex]

[tex]3m=6m-6[/tex]

Subtract 6m from both sides:

[tex]3m-6m=6m-6-6m[/tex]

[tex]-3m=-6[/tex]

Divide both sides by -3:

[tex]\frac{-3m}{-3}=\frac{-6}{-3}[/tex]

[tex]m=2[/tex]

Over which interval is the graph of y= cos(x) strictly increasing?

A. 0 B. 0 C.pi/2D. Pi< x <2pi

Answers

Answer:

D. [tex]\pi<x<2\pi[/tex]

Step-by-step explanation:

Given the function

[tex]y=cosx[/tex]

Kindly refer to the graph attached in the answer area.

Referring to the intervals [0, [tex]2\pi[/tex]].

It decreases from the interval [0, [tex]\pi[/tex]] and then starts increasing in the interval

[tex][\pi,2\pi][/tex].

Proving by taking derivative:

Taking derivative of the function, [tex]y=cosx[/tex]

[tex]\dfrac{dy}{dx}=-sinx[/tex]

In the interval [tex][\pi,2\pi][/tex], [tex]sinx[/tex] is negative i.e. [tex]sinx<0[/tex].

Therefore [tex]-sinx>0[/tex]

When, the derivative of a function is positive, then the function is strictly increasing.

So, the answer is:

D. [tex]\pi<x<2\pi[/tex]
