A triangle is a three-sided polygon. The sum of angles in a triangle is 180 degrees.

Types of triangles

An equilateral triangle : the three sides are equal in length.
An isosceles triangle : two sides are equal in length
A right angled triangle : an angle measures 90 degrees

The perimeter of a triangle is (8t -7 + u) centimeters

The perimeter of a triangle is the sum of the three lengths of the triangle

2t +2 + 6t - 7 + u -2

Combine similar terms

(2t + 6t) + (2 - 7 - 2) + u

Add combined similar terms

8t -7 + u

Solve for t: -4(t+4)=-8t-24

kotykmax [81]

Answer:

$\rm{-2$

Step-by-step explanation:

Hi there!

$\rm{-4(t+4)=-8t-24}$

$\rm{-4t-16=-8t-24$

$\rm{-4t+8t=-24+16$

$\rm{4t=-8$

$\rm{-2$

Thus, $-2$ is our final answer.

Hope it helps! Enjoy your day!

The height of a ball thrown vertically upward from a rooftop is modelled by h(t)= -4.8t^2 + 19.9t +55.3 where h (t) is the balls

nikitadnepr [17]

By applying the quadratic formula and discriminant of the quadratic formula, we find that the maximum height of the ball is equal to 75.926 meters.

<h3>How to determine the maximum height of the ball</h3>

Herein we have a quadratic equation that models the height of a ball in time and the maximum height represents the vertex of the parabola, hence we must use the quadratic formula for the following expression:

- 4.8 · t² + 19.9 · t + (55.3 - h) = 0

The height of the ball is a maximum when the discriminant is equal to zero:

19.9² - 4 · (- 4.8) · (55.3 - h) = 0

396.01 + 19.2 · (55.3 - h) = 0

19.2 · (55.3 - h) = -396.01

55.3 - h = -20.626

h = 55.3 + 20.626

h = 75.926 m

By applying the quadratic formula and discriminant of the quadratic formula, we find that the maximum height of the ball is equal to 75.926 meters.

A student says the prime factors of 17 are 1 and 17

Tju [1.3M]

That is correct as 17 is a prime number and can only be divided by 1 and itself

Hope this helps :)
