Answer: There are only two sides in each coin that Olga flips. If the coin lands on heads or tails then both will have a different result as one of them will be revealed to Olga as the coin stops flipping. For example Jessica flips a coin and it lands on tails and heads will not be revealed.

Find the value of all angles

o-na [289]

Answer:

Step-by-step explanation:

This means that <C and <F are congruent.

So 2x - 15 = x + 15 Add 15 to both sides

2x-15+15=x+15+ 15

2x = x + 30 Subtract x from both sides

2x-x=x-x+30

x = 30

Alex is planning to surround his pool ABCD with a single line of tiles. How many units of tile will he need to surround his pool

charle [14.2K]

Answer:

Hey there!

The answer to this question is the perimeter of the pool.

x^2+4.24^2=7.07^2

x=5.66.

5.66+4.24+5.66+4.24=19.8

Thus, 19.82 is the correct answer!

Let me know if this helps :)

Q7Which statement is incorrect for the graph of thefunction y = -5 cosGcos( 3 (x – 3)) +62The period is 4.The amplitude is 3.The

guajiro [1.7K]

The given function is,

$y=-5\cos (\frac{\pi}{2}(x-3))+6$

The graph can be drawn as,

The period will be distance between two consequetive maximas,

$\text{Period}=1-(-3)=4$

Thus, period is correct.

The amplitude can be determined as,

$\begin{gathered} Amplitude=\frac{\max -\min }{2} \\ =\frac{11-1}{2} \\ =5 \end{gathered}$

Thus, amplitue is incorrect.

The range is,

$y\in\lbrack1,11\rbrack$

Thus, the range is correct.

The midline is,

$\begin{gathered} \text{midline}=\frac{\max +\min }{2} \\ =\frac{1+11}{2} \\ =6 \end{gathered}$

Thus, the midline is correct.

Thus, option (b) is the solution.
