Answer:

$159$

Step-by-step explanation:

$56(12 - 9) - 6 \div 3 \times 3 - 3 \\ = 56(3) - 6 \div 3 \times 3 - 3 \\ = 56 \times 3 - 2 \times 3 - 3 \\ = 168 - 6 - 3 = 159$

1. Erin hits a golf ball off a tee. The height, yin yards, of the ball off the ground is given by

Sladkaya [172]

Answer:

The maximum height of the ball is 28.2 yards.

Step-by-step explanation:

When we have a quadratic equation in the following format:

$y = ax^{2} + bx + c$

The maximum value happens when

$x = x_{v} = \frac{-b}{2a}$

The maximum value will be $y(x_{v})$

In this problem, we have that:

$y = -0.0018x^{2} + 0.45x + 0.05$

$a = -0.0018, b = 0.45, c = 0.05$

$x = x_{v} = \frac{-b}{2a} = \frac{-0.45}{2*(-0.0018)} = 125$

The maximum height is:

$y(125) = -0.0018*(125)^{2} + 0.45*125 + 0.05 = 28.2$

The maximum height of the ball is 28.2 yards.

SOMEONE GIVE ME THE ANGLE DEGREES!!!! PLEASEEE I GIB FREE BRAINLIEST

tatiyna

The sum of angles of a triangle equals the straight angle (180°), therefore:

3x + 12x + 1 + 16x - 7 = 180

31x-6=180

31x = 180 + 6

31x = 186

x = 186/31

x = 6

Then, the angles are:

3(6) = 18°

16*6 - 7 = 89°

12(6) +1 = 73°
