Can someone help me with geometry! PLEASE!

Answers

Well, the sum of the angles in a triangle equals 180 degrees.
So you do 180 minus the two angles to get the third angle.
180 - 78.4 - 57.2 = 44.4
44.4 degrees

What is the value of n in the equation: 8n + 9 = -n +5

Answers

Answer:

n = -4/9

Step-by-step explanation:

8n + 9 = -n +5

Add n to each side

8n+n + 9 = -n+n +5

9n +9 = 5

Subtract 9 from each side

9n+9 - 9 = 5-9

9n /9 = -4/9

Divide each side by 9

n = -4/9

The value of expression is,

⇒ (2m - 8)² = 4m² - 24m + 64

What is Quadratic equation?

An algebraic equation with the second degree of the variable is called an Quadratic equation.

Given that;

The expression is,

⇒ (2m - 8)²

Now,

We know that,

The formula is,

⇒ (a - b)² = a² - 2ab + b²

Hence, We get;

⇒ (2m - 8)² = (2m)² - 2 × 2m × 8 + (8)²

                  = 4m² - 24m + 64

Thus, The value of expression is,

⇒ (2m - 8)² = 4m² - 24m + 64

The formula for the height of a ball as a function of time is given by the equation h = -16t^2 + vt + h, where h is the height of a ball in feet, v is the initial velocity of the ball in feet per second, h is the initial height of the ball in feet, and t is the time in seconds after the ball was thrown.If a ball is thrown from an initial height of 5 feet at an initial velocity of 20 feet per second, what is its height after 1 second?

Answers

It's really poor form to use 'h' to mean two different things in two different
places in the same formula.  Fortunately, we know what you mean.

H = h + vt - 16t²

You have said that ...
initial height = 5 feet
initial velocity = 20 feet per second, no direction given
time = 1 second


Since you gave us the magnitude of the initial velocity but not its direction,
there are a huge number of possibilities.  I'll focus only on two of them: 
20 feet per second straight down, and 20 feet per second straight up.

Initial velocity is downward:
H = (5) + (-20) (1) - 16 (1)²
H = 5 - 20 - 16 = 5 - 36 = 31 feet underground after 1 second

Initial velocity is upward:
H = (5) + (20) (1) - 16 (1)²
H = 5 + 20 - 16 = 25 - 16 = 9 feet above ground after 1 second
