In plane geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. Angles formed by two rays lie in a plane, but this plane does not have to be a Euclidean plane.

fomenos

Answer: It will take 4 seconds for the rock to hit the water.

Step-by-step explanation:

Given : Benjamin threw a rock straight up from a cliff that was 48 ft above the water.

If the height of the rock h, in feet, after t seconds is given by the equation

$h = -16 t^2+ 52 t + 48$

To find : Time taken for the rock to hit the water.

When rock hit the water height becomes zero , i.e. put h = 0 , we get

$-16 t^2+ 52 t + 48 =0$

Divide equation by 2 , we get

$-8t^2+26t+24=0$

The Laue of x for ax²+bx+c =0 is $x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}$

So , $t=\frac{-26\pm\sqrt{(26^{2}-4(-8)(24))}}{2(-8)}$

$t=\dfrac{-26\pm 38}{-16}\\\\ t=-\dfrac{-26+38}{-16}=-0.75\ \ t=\dfrac{-26-38}{-16}=4$

Since t cannot be negative , so t= 4

Hence, it will take 4 seconds for the rock to hit the water.

I need help with the first one

muminat

Answer and step-by-step explanation:

Becasue Manuel rode 8 miles in 40 minutes so he rode 1 mile in:

40 / 8 = 5 minutes

Because Eliza rode 5 miles in 30 minutes so she rode 1 mile in:

30/5 = 6 minutes

So manuel rode faster than eliza becasue:

- Manuel rode 1 mile in 5 mins

- Eliza rode 1 mile in 6 mins

So manuel rode faster than eliza

Hope this help you :3

Please help<br><br> Find the inverse function.<br> 8x – 4y = 24

Tom [10]

Answer:

Simplifying
8x + -4y = 24

Solving
8x + -4y = 24

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '4y' to each side of the equation.
8x + -4y + 4y = 24 + 4y

Combine like terms: -4y + 4y = 0
8x + 0 = 24 + 4y
8x = 24 + 4y

Divide each side by '8'.
x = 3 + 0.5y

Simplifying
x = 3 + 0.5y

God bless you and have a beautiful rest of your day!

Can someone help me please?

Viefleur [7K]

So, you start by separating the equation into two inequalities and you get
4x+1 > -7 and 4x +1 < 5

Solve these inequalities and you get your final answer:
x > -2 and x < 1

(The equalities symbols are supposed to have the "or equal" line beneath them, I was just too lazy to put them.)
