Answer:

394.2 ft

Step-by-step explanation:

7.8(9)=70.2

This is the measurement for the two triangular sides

9(12)(3)=324 This is the measurement for the three triangular sides

70.2 +324 = 394.2 APPROX

Answer:

umm, i think the question is incomplete

Step-by-step explanation:

An equation of a line in point-slope form:  y - y₁ = m(x - x₁)

1.

passes through (1, 9)   ⇒   x₁ = 1,  y₁ = 9

slope: m = 2

The equation:

y - 9 = 2(x - 1)          ←  point-slope form      

y - 9 = 2x - 2           {add 9 to both sides}

y = 2x + 7                ←    slope-intercept form  

2.

passes through (4, -1)   ⇒   x₁ = 4,  y₁ = -1

slope: m = -3

The equation:

y + 1 = -3(x - 4)           ←  point-slope form      

y + 1 = -3x + 12           {subtract 1 from both sides}

y = -3x + 11                ←    slope-intercept form  

Answer:

Vertex is (-4, -18)

Step-by-step explanation:

f(x) = [tex]ax^{2} +bx +c[/tex]

Let (h, k) be the vertex

An easy way to find h is to use the formula h = -b/2a

In your case where f(x) = [tex]x^{2} +8x - 2[/tex]   a = 2 and b = 8

So, h =  -8/2(1) = -8/2 = -4

Substitue -4 in for x to find k

k = ([tex]-4^{2}[/tex]) + 8(-4) - 2

  = (16) - 32 - 2

  = 16 - 32 - 2

  = -18

Vertex is (-4, -18)

Note:  Another way to find the vertex is to complete the square, but this can really be difficult in some cases

Answer:

Option D, (-4,-18)

Answer:

B. false

Answer:

118degrees

Step-by-step explanation:

Assuming we are given the following and m<k and ,<N lies on the same straight line, hence;

m<K = 62 degrees

n<N = ?

Since are on the same straight line, hence;

m<N + m<K = 180

m<N + 62 = 180

m<N = 180 - 62

m<N  = 118

Hence the measure of m<N is 118degrees

Answer:

3x^2 - 17x + 24

Step-by-step explanation:

(x – 3)(3x – 8)

3x^2 + (-8x) + (-9x) + 24

3x^2 - 17x + 24

Answer:

Answer:

0.075 inches per year

Step-by-step explanation:

The average rate of change is measured as

( difference in diameter ) ÷ ( difference in years )

= ( 251 - 248 ) ÷ ( 2005 - 1965 )

= 3 inches ÷ 40 years

= 0.075 inches per year

Answer:

c

Step-by-step explanation:

Answer:

Step-by-step explanation:

Putting values in the equation

A = 1/2(7)(8 + 14)

= 1/2(7)(22)

= 1/2(154)

= 77 ft. sq

Option A is the correct answer

Answer:

144

Step-by-step explanation:

24 books at 6 points each would be 24 x 6 which equals 144

Answer:

They'll have 144 points if they read 24 books.

Step-by-step explanation:

6 x 24 = 144

Answer:

=1,2

He will complete the race in 1.2 hours time.

Hence, option B is correct.

A measurement unit is a standard quality used to express a physical quantity. Also it refers to the comparison between the unknown quantity with the known quantity.

Given that,

The distance completing in 1 hour = 20 miles

So 1 miles of distance is covered in = 1/20 hours

It is also given that,

The distance of rally = 24 miles.

Therefore,

The time taken to cover 24 miles = 24/20

                                                        = 1.2

Thus,

The required time = 1.2 hours

Answer:

[tex] m\angle SXW =113\degree [/tex]

Step-by-step explanation:

In circle with center X, VS is diameter.

So [tex] \widehat {SWV} [/tex] is a semicircular arc.

[tex] \therefore m\widehat{SWV} = 180\degree [/tex]

[tex] \therefore (12x+7)\degree + (21x +8)\degree = 180\degree [/tex]

[tex] \therefore (33x+15)\degree = 180\degree [/tex]

[tex] \therefore 33x+15 = 180 [/tex]

[tex] \therefore 33x = 180-15 [/tex]

[tex] \therefore 33x = 165 [/tex]

[tex] \therefore x =\frac{165}{33} [/tex]

[tex] \therefore x =5 [/tex]

[tex] m\angle SXW =m\widehat{SW} [/tex]

(Measure of central angle is equal to the measure of its corresponding minor arc)

[tex] m\angle SXW =(21x + 8)\degree [/tex]

[tex] m\angle SXW =(21\times 5+ 8)\degree [/tex]

[tex] m\angle SXW =(105+ 8)\degree [/tex]

[tex] m\angle SXW =113\degree [/tex]
