x2-4x=-4 Solve using quadratic formula (find x)

Answer:

yes

Step-by-step explanation:

this is because you both have to get 2 of them on a head or tails

The given game is fair, as both, you and your friend have equal probabilities of winning.

The probability of an event is the fractional value showing how likely an event is to occur. It is determined by the formula,

The probability of an event

= the number of outcomes favorable to the event/total number of outcomes.

All possible outcome when two coins are tossed is {HH, HT, TH, TT}

∴ The total number of outcomes = 4.

For you to win, we need both heads, that is {HH}.

∴ Number of outcomes in your favor = 1

Probability(you win) = 1/4

For a friend to win, we need both tails, that is {TT}.

∴ Number of outcomes in your friend's favor = 1

Probability(friend win) = 1/4

∵ Probability(you win) = Probability(friend win), we can say that the game is fair.

Answer:

C. 113.04 ft²

Step-by-step explanation:

Area of a circle = π×radius²

Since diameter is 12, the radius is 6

π×(6)²  =   π×36   =   113.04

Answer:

30° , 60° , 90°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

sum the 3 angles and equate to 180

x + 2x + 3x = 180 , that is

6x = 180 ( divide both sides by 6 )

x = 30

2x = 2 × 30 = 60

3x = 3 × 30 = 90

the 3 angle measures are 30° , 60° , 90°

Answer:

(g ￮ f)(- 5) = 4

Step-by-step explanation:

evaluate f(- 5) then substitute the value obtained into g(x)

f(- 5) = (- 5)² + 6(- 5) + 3 = 25 - 30 + 3 = - 2 , then

g(- 2) = 2(- 2) + 8 = - 4 + 8 = 4

(g ￮ f)(- 5) = 4

Answer:

the 35th term or a(35) is 69

Step-by-step explanation:

the first thing you must do to solve this equation is to write for the nth term

this is

a(n) = 209 - 4n

i got 209 by adding 4 to 205 to find the 0th term

so to solve the equation for the 35th term oyu just plug it in

a(35) = 209 - 4(35)

a(35) = 209 - 140

a(35) = 69

Answer:

a = 146

Step-by-step explanation:

The line is 180 degrees so one angle is 34 degrees and the other one would have to add up with it to make 180 degrees. This is where the 146 degrees comes in.

146 + 34 = 180 = degrees

Explanation:

I'm assuming the rope is fully taut and connects the top of the flag pole with the tip of the shadow.

Draw a right triangle that has a horizontal leg of 5 feet and a hypotenuse of 13 feet. I'll call these a = 5 and c = 13.

Use the pythagorean theorem to find b

[tex]a^2 + b^2 = c^2\\\\5^2 + b^2 = 13^2\\\\25 + b^2 = 169\\\\b^2 = 169-25\\\\b^2 = 144\\\\b = \sqrt{144}\\\\b = 12[/tex]

The vertical leg of the right triangle is 12 feet, which is the height of the flag pole. We have a 5-12-13 right triangle.

Explanation:

The equator is the middle-most horizontal line. This is the thickest horizontal line of the group.

The prime meridian is the thickest vertical line shown at the center.

Start where those two lines cross. We call this 0 degrees North and 0 degrees East.

Then move 20 degrees west and 20 degrees north to arrive at point A.

Therefore, we can describe the absolute location of point A by saying "20° N, 20° W". Always list the north/south coordinate first (aka the latitude) before listing the east/west coordinate (longitude).

You probably have come across this type of notation before if you have worked with GPS.

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

Point B is located at the absolute position of 40° N, 120° E

The 40 is from moving 2 ticks up from the center. Each tick is 20 degrees, so 2*20 = 40 degrees total north. The 120 is from 6 movements to the east, so 6*20 = 120 degrees east in total.

Like with point A, and the rest of the points as well, we always start at the center.

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

Again start at the intersection of the equator and the prime meridian.

We then move 1 tick down, to move 1*20 = 20 degrees south.

We also move 6 tickmarks west to move 6*20 = 120 degrees west.

Therefore, point C's absolute location is 20° S, 120° W

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

The same idea will play out to locate points D and E.
