Pls help me with this. i have finals tomorrow and i dont get this

Serhud [2]

Answer:

We're here to help! Let me take this slowly.

44. First, we have the x-coordinate of the vertex to be -b/2a which is 16. Plugging 16 in, we have y-coordinate to be 135.

Notice that it is y=(x-7)(x-1).

So, we can just plug in values for x and y. Once you've got a lot of points, you can connect the dots and see how you can graph it.

The axis of symmetry is the x-coordinate of the vertex, or x=16.

45. Do the same method as mentioned above. I personally think that using transformations are more confusing, but that's just opinion. The axis of symmetry is x=-(-4)/2(-1) = -2, so axis of symmetry is x=-2.

46. We have x=-4 or x = 1/2.

47. We have (y-7)(y-1) = 0 ==> y=7,y=1

48. We have w^2 = 9, so w = +/- 3

49. We have (p-10)(p-3)=0, so p=10, p=3

50. We have (3m+1)(m+3)=0, so m=-1/3, m=-3

Molly is painting a model house and needs to know how much paint she will need. She knows the surface area of the prism is 216 s

mrs_skeptik [129]

Answer:

1. Base of pyramid; 6 in by 6 in

2. Base of prism; Its dimensions are also 6 in by 6 in, located at the bottom of the house and will not be seen, so it does not require painting.

3. twice the area of the square

4. Area = 228 inches squared

Step-by-step explanation:

For question 4, the area Molly needs to paint is found by adding all the surface areas and subtracting the 2 surfaces that will not be painted: base of pyramid and base of prism (outlined in red). According to the picture, these are both squares with 6 by 6 dimensions.

<h3>Step 1. Add all surface areas together</h3>

Prism: 6 surfaces

Surface area = 216 inches sq

Front = 6 x 6 = 36
Back = 6 x 6 = 36
Top = 6 x 6 = 36
Bottom (base) = 6 x 6 = 36
Side = 6 x 6 = 36
Other side = 6 x 6 = 36

Pyramid: 5 surfaces

Surface area = 84 inches sq

Bottom (base) = 6 x 6 = 36
Front triangle = (6 x 4)/2 = 12
Back = (6 x 4)/2 = 12
Side = (6 x 4)/2 = 12
Other side = (6 x 4)/2 = 12

TOTAL surface area: 216 inches + 84 inches = 300 inches sq

<h3>Step 2. Subtract surfaces that are NOT being painted</h3>

300 - base of pyramid - base of prism

300 - 2(36)

300 - 72

<u>228 inches sq</u>

A = {1, 3, 5, 7, 9} B = {2, 4, 6, 8, 10} C = {1, 5, 6, 7, 9} A ∩ (B ∪ C) =

vovikov84 [41]

A = {1, 3, 5, 7, 9}
B = {2, 4, 6, 8, 10}
C = {1, 5, 6, 7, 9}

(B ∪ C) = {1, 2, 4, 5, 6, 7, 8, 9, 10}
so
A ∩ (B ∪ C) = {1, 5, 7 , 9}

What is the population standard deviation of this data set?*

Minchanka [31]

Answer:

C) 2

Step-by-step explanation:

step 1: Find mean of data set

2+4+4+5+7+8 = 30

30/6 = 5

Mean = 5

step 2: subtract each data value from the mean and square it

5-2 = 3; 3² = 9

5-4 = 1; 1² = 1

5-5 = 0; 0² = 0

5-7 = -2; (-2²) = 4

5-8 = -3; (-3²) = 9

Add the squared results:

9+1+1+0+4+9 = 24

Divide 24 by 6 to get the Variance of 4

Take the square root of the Variance to get the Standard Deviation

$\sqrt{4}$ = 2
