Answer:

ddd

Step-by-step explanation:

Divide 5a2 + 6a - 9 into 25a4 + 19a2 - a - 78.


                               5a^2 -6a +20

                             -------------------------------------------------                    

   5a^2+6a-9        25a^4 + 0a^3 +19a^2 - 1a - 78

                             25a^2 + 30a^3 - 45a^2

                            ------------------------------------------------(subtract)

                                         -30a^3 +64a^2 -1a

                                         -30a^3 -36a^2 +54a

                            -----------------------------------------------(subtract)

                                                     100a^2 -55a  -78

                                                     100a^2 +120a - 180

                              ------------------------------------------------------

                                                                   - 175a +102

Quotient : 5a^2 -6a+20

Remainder : -175+102

Answer is : 5a^2 -6a+20 + \frac{-175a+102}{5a^2+6a-9}

We firstly calculate the angle at the bottom left of the triangle(theta)..,

; Angle theta...

tan theta = 9/11

Angle theta = tan^-1(9/11)

; Angle theta = 39.3°

Then height x...we then use the smaller triangle..,

; tan (39.3°) = x/5.5

; x = 5.5 tan(39.3°)

Hence... x = 4.5

Answer:

373.66 cm².

Step-by-step explanation:

The following data were obtained from the question:

Pi (π) = 3.14

Radius (r) = 7 cm

Slant height (l) = 10 cm

Surface Area (SA) =?

The surface area of the cone can be obtained by using the following formula:

SA = πr² + πrl

SA = (3.14 × 7²) + (3.14 × 7 × 10)

SA = (3.14 × 49) + 219.8

SA = 153.86 + 219.8

SA = 373.66 cm²

Therefore, the surface area of the cone is 373.66 cm².

Given the table of values below, which of the following ordered pairs are found on the graph of the inverse function? A. (-2, -1
Ainat [17]

Given:

The of values of a function.

To find:

The ordered pairs that are found on the graph of the inverse function.

Solution:

If a function is defined as

f(x)=\{(x,y):x\in R,y\in R\}

Then its inverse function is defined as

f^{-1}(x)=\{(y,x):x\in R,y\in R\}

From the given table it is clear that, the ordered pairs of the function f(x) are :

\{(-2,-14),(-1,10),(0,6),(1,2),(2,-2)\}

So, ordered pairs of the inverse function are :

\{(-14,-2),(10,-1),(6,0),(2,1),(-2,2)\}

Therefore, the correct option is B.

dezoksy [38]
<span>Answer: Skewed to right with mean 0 and S.D. 1 Explanation: Let's assume the z-scores as a linear transformation. then z=(x-mean)/S.D. = (x-30)/15 z(mean) = (30-30)/15= 0 z(sigma) = 15/15 = 1 Note: Shape does not change.</span>
