Gala2k [10]3 years ago
7 0

Answer:

False

Step-by-step explanation:

11 times 11 is 121

5 times 5 is 25

13 times 13 is 169

121+25 doesnt equal 169

this means it is not a right angled triangle as it does not follow pythag

leonid [27]

Answer:

The maximum height of the particle is 100 ft

A is correct

Step-by-step explanation:

A particle is moving along a projectile path where the initial height is 96 feet with an initial speed of 16 feet per second.

The standard equation of parabolic projectile.

h(t)=-16t^2+v_0t+h_0

where,

v_0=16\ ft/s

h_0=96\ ft

h(t)=-16t^2+16t+96

So, we get the parabolic equation of path.

The maximum value at vertex.

t=-\dfrac{b}{2a}

t=-\dfrac{16}{-32}=\dfrac{1}{2}

Maximum at t=0.5

h(0.5)=-16(0.5)^2+16(0.5)+96

h(0.5)=100

Hence, The maximum height of the particle is 100 ft

What is the vertex of the parabola? y + 4 = 1/2 (x - 7)^2<br>Please help fast !
Ber [7]
Get into form (x-h)^2=4p(y-k)
vetex is (h,k)

so
1/2(x-7)^2=y+4
times 2 both sides
(x-7)^2=2(y+4)
(x-7)^2=4(1/2)(y-(-4))
vertex is (7,-4)

Please answer thanks you (:
dimulka [17.4K]

Answer:

B

Step-by-step explanation:

I believe it is B because it is the only one that doesnt have x values that repeat and give different answers.

Ex. For a, the x value in the first and third coords gives both 1 and 3 as answers.

Every x has to have a unique y value, so

(2,10) (3,12) is ok, but (2,10) (2,12) is not.

Sorry if this doesnt make sense haha
