Answer:

$a=5 \sqrt{7}$

Step-by-step explanation:

Pythagoras Theorem explains the relationship between the three sides of a right triangle. The square of the hypotenuse (longest side) is equal to the sum of the squares of the legs of a right triangle:

$a^2+b^2=c^2$

where:

a and b are the legs of the right triangle
c is the hypotenuse (longest side) of the right triangle

Given:

b = 9
c = 16

Substitute the given values into the formula and solve for a:

$\begin{aligned}a^2+b^2 & = c^2 \\\implies a^2+9^2 & =16^2\\a^2+81 & =256\\a^2+81-81 & =256-81\\a^2 & =175\\\sqrt{a^2} & =\sqrt{175}\\a & =\sqrt{25 \cdot 7}\\& = \sqrt{25}\sqrt{7}\\& =5\sqrt{7}\end{aligned}$

Therefore, the measure of the third side of the given right triangle is $5 \sqrt{7}$

All of the numbers in the sequence are being divided by 6. To complete it, we will divide 96 by 6.
96 ÷ 6 = 16
The answer is 16.

In a volleyball game, a player on one team spikes the ball over the net when the ball is 10 feet above the court. The spike driv

Fynjy0 [20]

Answer:

4.75 seconds

Step-by-step explanation:

Initial height of the ball from the ground = 10 feet

Upward initial velocity given = 55 feet per second

Value of g ( acceleration due to gravity) = 32.2 feet per s²

Motion of the ball:

The ball first goes vertically upwards, gravity decelerates the body and it momentarily comes to rest at a point in its upward trajectory, which is the point of maximum height. From this point, to the ground, the ball behaves as a freely dropped body.

Till the ball reaches its maximum height:

u = + 55

v = 0 ( final velocity is zero)

a = - 32.2 (since it is deceleration)

we know that v = u + at

⇒ 0 = 55 - 32.2t

⇒ t = 1.7 s

Also , we have s = ut + (1/2)at²

Here, s is the maximum height from the point where ball is thrown

So, s = 55(1.7) - (0.5)(32.2)(1.7)(1.7)

⇒ s = 140 feet

So at a height of 140 feet + 10 feet (initial height) = 150 feet, the ball acts as a freely dropped body.

Here, u = 0

a = +32.2

s= 150

s = ut + (1/2)at²

⇒ 150 = 0.5 ( 32.2) (t²)

⇒ t² = 300/32.2 = 9.31

⇒ t = 3.05 sec

So total time = 1.7 + 3.05 = 4.75 seconds

According to the graph, what is the factorization of x - 5x + 6? y=x2.5x + 6 5 A. (x - 3)(x-2) B. (x+3)(x - 2) C. (x-3)(x + 2) O

8_murik_8 [283]

Given:

To find the factorization of the graph,

$x^2-5x+6$

By factorization, we get

$\begin{gathered} x^2-2x-3x+6 \\ x(x-2)-3(x-2) \\ (x-3)(x-2) \end{gathered}$

Hence option a) is the correct answer.
