What is the perimeter of the triangle. Please look at photo. I need you help. Thank you in advance♡​
bulgar [2K]
Answer : 12.9 units

explanation :

Sides: a = 7.616   b = 7.211   c = 13.038

Area: T = 23
Perimeter: p = 27.865
Semiperimeter: s = 13.933

Angle ∠ A = α = 29.291° = 29°17'29″ = 0.511 rad
Angle ∠ B = β = 27.597° = 27°35'50″ = 0.482 rad
Angle ∠ C = γ = 123.111° = 123°6'41″ = 2.149 rad

Height: ha = 6.04
Height: hb = 6.379
Height: hc = 3.528

Median: ma = 9.823
Median: mb = 10.05
Median: mc = 3.536

Inradius: r = 1.651
Circumradius: R = 7.783

Vertex coordinates: A[3; -1] B[16; -2] C[9; -5]
Centroid: CG[9.333; -2.667]
Coordinates of the circumscribed circle: U[0; 0]
Coordinates of the inscribed circle: I[3.158; 1.651]

Exterior (or external, outer) angles of the triangle:
∠ A' = α' = 150.709° = 150°42'31″ = 0.511 rad
∠ B' = β' = 152.403° = 152°24'10″ = 0.482 rad
∠ C' = γ' = 56.889° = 56°53'19″ = 2.149 rad

State the coordinate of the image of the given point B (-10,-6) under a dilation with center at the origin
Tpy6a [65]
I belive you just multiply each point by1/2. So -10/2=-5 and -6/2=-3
So point b will be(-5,-3)

The equation h(t)=−16t2+120t+65 gives the height of a firework, in feet, t seconds after it is launched from a platform.
kakasveta [241]

Answer:

The height of the platform is 65 ft

Step-by-step explanation:

Let

t -----> the time in seconds after the launch of the fireworks from a platform

h(t) ----> the height of a firework in feet

we have

h(t)=-16t^{2}+120t+65

we know that

The height of the platform is when the value of t is equal to zero (y-intercept)

For t=0

h(0)=-16(0)^{2}+120(0)t+65

h(0)=65\ ft

therefore

The height of the platform is 65 ft
