Answer:

Option B

Step-by-step explanation:

Given equation is

$y=\frac{-1}{5(x+5)^{2} } +2$

The original graph would be

$y=-\frac{1}{x^{2} }$

From this transformations done are

a) horizontal shift of 5 units to the left

b) shrink vertical by scale factor 1/5

c) vertical shift of 2 units up

Hence option A is not right

Option B is right.

Similarly C and D are not right.

What is the measure of arc AC?

If Im not mistaken, the answer should be d because if you add all the degrees up, then you would get 222. And if you subtract 360 from 222 you get 138. I hope this helps. :)

Two number cubes are rolled.

hichkok12 [17]

Answer:

When two number cubes are rolled,

Sample space= Total Possible outcome {11,22,33,44,55,66,12,21,13,31,14,41,15,51,16,61,23,32,24,42,25,52,26,62,34,43,35,53,36,63,45,54,46,64,56,65}=36

Probability of an event = \frac{\text{Total favorable outcome}}{\text{Total possible outcome}}

Sum of 4 is obtained when ={13,31,22}=3

Probability of getting 4 when 2 number cubes are rolled= \frac{3}{36}=\frac{1}{12}

Sum of the numbers is greater than 9= 10, 11,12={55,64,46,56,65,66}=6

Probability of getting(Sum of the numbers is greater than 9)=\frac{6}{36}=\frac{1}{6}

Find the 11th term of the geometric sequence 1, 4, 16, ...

drek231 [11]

Answer:

a(11) = 4^10 = 1048576

Step-by-step explanation:

The first term of this geometric sequence, a(1), is 1, and the common ratio, r, is 4. Each new term is 4 times the previous term. Thus,

a(n) = 1*4^(n - 1), and

a(11) = 4^10 = 1048576

(16+3)-10÷5×3^2? with explanation step by step

NemiM [27]

$(16+3)-10\div5\times3^2\text{ = 1}$

Here, we want to simplify the given expression

We shall use the order of simplification for this

The order is PEDMAS

We shall start with the terms in parentheses before we move to the exponents

We have;

$\begin{gathered} (16+3)-10\div5\times3^2 \\ =\text{ 19-10}\div5\times3^2 \end{gathered}$

Next is the exponent

$=\text{ 19-10}\div5\times9$

The next thing to do is to divide

$=\text{ 19-}2\times9$

The next thing to do is to multiply

$=\text{ 19-18}$

We then proceed to subtract;

$=\text{ 19-18 = 1}$
