The function f(t) = −5t 2 + 20t + 60 models the approximate height of an object

1 answer:

3 0

Plug in f(t) = 0. We do this because f(t) represents the height and a height of 0 means you're at the ground.

f(t) =-5t^2 + 20t + 60

0 = -5t^2 + 20t + 60

-5t^2 + 20t + 60 = 0

Now solve for t using the quadratic formula

I) Consider the following figure,

qwelly [4]

Step-by-step explanation:

If PQRS is a quadrilateral inscribed in a circle, then the opposite angles of the quadrilateral are supplementary.

y + 68° = 180° { being opposite angles of cyclic quadrilateral }

y = 180° - 68°

y = 112°

x + 82° = 180° { being opposite angles of cyclic quadrilateral }

x = 180° - 82°

x = 98°

Hope it will help :)❤

State the domain and range of the following function:

mojhsa [17]

Answer:

$Domain = \{-3,0,2,1,6,3\}$

$Range = \{4,6,-2,-3,-7,2\}$

Step-by-step explanation:

Given

$\{(- 3,4), (0,6), (2, - 2), (1, - 3), (6, - 7), (3, 2)\}$

Required

The domain and range

A function is represented as:

$Function = \{(x_1,y_1),(x_2,y_2),....(x_n,y_n)\}$

Where

$x \to$ domain

$y \to$ range

So, we have:

$Domain = \{-3,0,2,1,6,3\}$

$Range = \{4,6,-2,-3,-7,2\}$
