Please help! I need to find the slope of this line.

larisa86 [58]

The slope is half, since when the equation is divided by two so that the y value is one, the x coefficient is half, so the slope is half.

Find the perimeter of quadrilateral ABCD. Round to the nearest tenth.

Olegator [25]

Answer:

14.6 units

Step-by-step explanation:

AB = $\sqrt{(1-3)^2+(3-5)^2}$

AB = $\sqrt{8}$

BC = $\sqrt{(3-1)^2+(-1-3)^2}=\sqrt{20}$

CD = $\sqrt{(5-3)^2+(3-(-1))} = \sqrt{20}$

DA = $\sqrt{(5-3)^2+(3-5)^2} = \sqrt{8}$

Primeter = $\sqrt{8} + \sqrt{20} + \sqrt{20} +\sqrt{8} = 14.6$

A ball is thrown off the roof of the school. Its path can be described by the equation: h(t) = -2t^2 + 8t + 10, where h is heigh

zimovet [89]

Answer:

10 meters

Step-by-step explanation:

The given function $h(t)=-2t^2+8t+10$ represents the height, $h$ , in meters, $t$ seconds after the ball is thrown.

Since the ball is thrown off the roof, then ball's height will be equal to the roof's height before being thrown (0 seconds). Therefore, substitute $t=0$ into the given function $h(t)=-2t^2+8t+10$ :

$h(0)=-2(0^2)+8(0)+10,\\h(0)=0+0+10,\\h(0)=\boxed{10\text{ meters}}$

Therefore, the building is 10 meters tall.

tester [92]

Answer:

$\large\boxed{\dfrac{1}{a^{-\frac{5}{6}}}=a^\frac{5}{6}}$

Step-by-step explanation:

$a^{-n}=\dfrac{1}{a^n}\\\\-------------------\\\\\dfrac{1}{a^{-\frac{5}{6}}}=\dfrac{1}{\frac{1}{a^{\frac{5}{6}}}}=a^\frac{5}{6}$
