Pablo and max's follows a flight pattern approximatley modled by the equation h(t)=-8t^2+16t+2 where h(t)is their rocket's heigh

kodGreya [7K]

Answer: 2.11 s

Step-by-step explanation:

Given

Equation of rockets height is given by

$\Rightarrow h(t)=-8t^2+16+2$

Height will be zero once the rocket lands on the ground

So, we can write

$\Rightarrow h(t)=0\ \text{or}\ -8t^2+16t+2=0\\\Rightarrow 8t^2-16t-2=0\\\\\Rightarrow t=\dfrac{16\pm \sqrt{(-16)^2-4(8)(-2)}}{2\times 8}\\\\\Rightarrow t=\dfrac{16\pm \sqrt{320}}{16}\\\\\text{Neglecting negative value of t}\\\\\Rightarrow t=\dfrac{16+17.888}{16}=2.11\ s$

The measure of each interoir angle of a regualr polygon is 144 . how many sides does this polygon have

egoroff_w [7]

Each Interior Angle = 180 - (360 / number of sides)
# of sides = -360 / (Each Interior Angle -180)
# of sides = -360 / (144 -180)
# of sides = -360 / -36
# of sides = 10

Find the hypotenuse for a right triangle with legs 8 and 12. Write your answers in simplest exact form

konstantin123 [22]

Answer:4√(13)

Step-by-step explanation:

Adjacent=12

Opposite=8

Hypotenuse=√((adjacent)^2+(opposite)^2)

hypotenuse=√(12^2+8^2)

Hypotenuse=√(12x12+8x8)

Hypotenuse=√(144+64)

Hypotenuse=√(208)

Hypotenuse=√(16x13)

hypotenuse=√(16) x √(13)

Hypotenuse=4 x √(13)

Hypotenuse=4√(13)

Consider that an = 4n-1 represents a sequence. what is the tenth term?n-1 is a exponent

Katen [24]

Geometric sequence since exponent
$a_n=a_1r^{n-1}$
a1=firs term
r=common ratio
n=which term

no first term given, or is there?
4^(n-1), first term is 1, common ratio is 4

just plug in 10 for n
$a_{10}=(1)4^{10-1}$
$a_{10}=4^{9}$
$a_{10}=4^{9}$
$a_{10}=262144$
tenth term is 262144
