For the figure shown, find m<1.

sdas [7]

Answer:

Step-by-step explanation:

Sum of angles of a triangle = 180

So, 56 + 58 + x = 180

114 + x = 180

x = 116

Now ∠ 1 + ∠x = 180 [ straight line angles]

∠ 1 + 66 = 180

∠1 = 180 - 66 = 114°

You can use the rule : Exterior angle = sum of 2 interior opposite angles.

56 + 58 = ∠1

114 = ∠1

plz hurry!! A person standing close to the edge on top of a 108-foot building throws a ball vertically upward. The quadratic fun

Archy [21]

Answer:

The maximum height of the ball is 380.25 feet in the air.

Step-by-step explanation:

The quadratic function:

$h(t)=-16t^2+132t+108$

Models the ball's height h(t), in feet, above the ground t seconds after it was thrown.

We want to determine the maximum height of the ball.

Note that this is a quadratic function. Therefore, the maximum or minimum value will always occur at its vertex point.

Since our leading coefficient is leading, we have a maximum point. So to find the maximum height, we will find the vertex. The vertex of a quadratic equation is given by:

$\displaystyle \left(-\frac{b}{2a},f\left(\frac{b}{2a}\right)\right)$

In this case, a = -16, b = 132, and c = 108. Find the t-coordinate of the vertex:

$\displaystyle t=-\frac{132}{2(-16)}=-\frac{132}{-32}=\frac{33}{8}=4.125$

So, the maximum height occurs after 4.125 seconds of the ball being thrown.

To find the maximum height, substitute this value back into the equation. Thus:

$h(4.125)=-16(4.125)^2+132(4.125)+108=380.25\text{ feet}$

The maximum height of the ball is 380.25 feet in the air.

What is the solution of this equation? -1y = -4

tigry1 [53]

Answer:

y = 4

Step-by-step explanation:

-1y = -4

Divide both sides by -1 to get y by itself.

-1/-1 = -4/-1

y = 4

It's positive because there are two negatives, which mean they cancel out.
