Find mFDE, given that EF is a diameter of the circle

Mathematics
1 answer:
muminat3 years ago
8 0
The measure of angle FDE must be 90 degree, if D is a point on the circle. If D is not a point on the circle, we are unable to determine the measure of angle FDE.

When you have angle with the vertex on a circle and the sides go through the ends of the diameter, the angle is always a right angle.

You and a friend play a game where you each toss a balanced coin. If the upper faces on the coins are both tails, you win $1; if
dsp73

Answer:

Step-by-step explanation:

Given that you and a friend play a game where you each toss a balanced coin.

If the upper faces on the coins are both tails, you win $1;

if the faces are both heads, you win $2;

if the coins do not match (one shows a head, the other a tail), you lose $1 (win (−$1)).

Let Y be the amount won

Then Y can take values as 1,2 and -1

P(Y=1) =P(TT) = 0.25\\P(Y=2) = P(HH) = 0.25\\P(Y=-1) = P(HT)+P(TH) = 0.5

The above is the probability distribution for Y.

lukranit [14]
The ratio would be 36 to 18
because 9*4=36
and 18 is 18 lol
so (calculator) 1,080/9=120
120
20*18=180
100*9=900
so

idek man this is hard as hell,I tried tho,try to do the rest of the problem from what I have set up

Find the approximate solution(s) to each of the following equations graphically. Use technology to support your
ser-zykov [4K]

Answer: x" = 5.69

Step-by-step explanation:

The graphic solution is attached.

Verifying the solution:

Existence condition: x > 0

2x - 4 = √x + 5

√x =2x - 4 - 5

√x =2x - 9 (²)

x = (2x - 9)²

x = 4x² - 36x + 81

4x² - 36x - x + 81 = 0

4x² - 37x + 81 = 0

Δ = -37² - 4.4.81 = 1369 - 1296 = 73

x = 37 ±√73/8                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          

x' = 3.55

x" = 5.69

checking:

2*3.55 - 4 = 3.1

√3.55 + 5 = 6.88 Its not the same ∴ 3.55 is not a solution

2*5.69 - 4 = 7.39

√5.69 + 5 = 7.39 ∴ it's the only solution
