Answer:

31

Step-by-step explanation:

first find f(-3)

f(-3) = (-3)^2 +5

       = 9+5 = 14

The find g(f(-3) = g(14)

                         = 3*14-11

                           = 42-11

                             =31

Find the modulus of the complex number 6-2i
Papessa [141]

Answer:

The modulus of the complex number 6-2i is:

|z|\:=2\sqrt{10}

Step-by-step explanation:

Given the number

6-2i

We know that

z = x + iy

where x and y are real and \sqrt{-1}=i

The modulus or absolute value of z is:

|z|\:=\sqrt{x^2+y^2}

Therefore, the modulus of 6-2i  will be:

z=6-2i

z=6+(-2)i

|z|\:=\sqrt{x^2+y^2}

|z|\:=\sqrt{6^2+\left(-2\right)^2}

    =\sqrt{6^2+2^2}

    =\sqrt{36+4}

    =\sqrt{40}

    =\sqrt{2^2}\sqrt{2\cdot \:5}

    =2\sqrt{2\cdot \:5}

   =2\sqrt{10}

Therefore, the modulus of the complex number 6-2i is:

|z|\:=2\sqrt{10}

Greg goes fishing every day for a week. On the first day he catches seven fish and each
Oliga [24]

so first day and so on

7, 10, 13,....

as you can see it's an arithmetic progression

so sum for nth term= n/2 { 2a + (n-1) d}

it's the sum of the 7th term

so

7/2 { 7 ×2 + ( 7-1) 3}

7/2 × 32

7× 16

112 fishes

Multiple choice question please answer it for me
timofeeve [1]
The answer is the second choice, or B; 240 ft^2.

You have to find the area of all four triangles and just add those all together. 

Two of the triangles have an area of 
5*16=80
Multiply that by two
80*2=160

The other two smaller triangles have an area of 
8*5=40
Multiply that by 2 also
40*2=80

Add 160+80 and the answer is 240.

What is the answer to <br>2x+3=4x+6-(2x+3)
Grace [21]

I am still learning, and am most likely incorrect.

I believe you remove the 3's since their not needed, and do this:

2x = 4x + 6 - (2x)

so then just ignore "x" and do this:

2 = 4 + 6 - 2

2 = 10 - 2

2 = 8


x = 8
