Answer:

Options: 1, 4 & 6

Step-by-step explanation:

Yes:

1. $-1(x-1)^{2} +9=-1(x^{2} -2x+1)+9=-x^{2} +2x-1+9=-x^{2} +2x+8$

4. $-x^{2} +2x+8$

6. $(x+2)(4-x)=2x-x^{2} +8=-x^{2} +2x+8$

No:

2. $-(x-9)^{2} +1=-(x^{2} -18x+81)+1=-x^{2} +18x+81+1=-x^{2} +18x+82$

3. $x^{2} +2x-8$

5. $(x+2)(x-4)=x^{2} -2x-8$

Hope this helps

Help!! A cylindrical water tank is being filled with a hose. The depth of the water increases by 1 1/4 ft per hour. How many hou

nordsb [41]

Depth: 7/2 feet
Rate: 5/4 feet per hour

Time = depth / rate of filling
Time = 7/2 / 5/4
Time = 14/5
Time = 2 4/5 hours

What is the distance between points v (3,3) and w (-2,-3) round to the nearest tenth if necessary

Vinil7 [7]

Answer:

7.81 u

Step-by-step explanation:

<u>Given :- </u>

Two points (3,3) and (-2,-3) is given to us.

And we need to find out the distance between the two points . So , here we can use the distance formula to find out the distance. As,

$:\implies$ D = √{(x2-x1)² + (y2-y1)²}

$:\implies$ D =√[ (3+2)² +(-3-3)²]

$:\implies$ D =√[ 5² +6²]

$:\implies$ D =√[ 25 +36]

$:\implies$ D = 61

$:\implies$ D = 7.81

<h3>Hence the distance between the two points is 7.81 units .</h3>

The triangle shown is translated up 5. What are the new coordinates of point C?

ehidna [41]

Answer:

(3,6)

Step-by-step explanation:

The triangle shown in figure is translated up 5

To find how coordinate of C

Original coordinate of C:(2,1),

Translation has two types: verbal and horizontal.

For verbal translation: either shift up or down

1. For up shift: add value in Y-cordinate

2. For down shift: subtract value in y coordinate

• For horizontal translation: either shift left or right

I. For left shift: subtract value in x-cordinate

II. For right shift: add value in x-cordinate

C: (3,1)shift 5 unit up

So, add 5in y-cordinate

(3,1)→(3,1+5)

(3,1)→(3:6)

Hence, the new coordinate of point C is (3,6)
