Let d to be the distance:

7. A(2,3), B(6,3), C(2,7)

dᵃᵇ= √((2-6)²+(3-3)²)

dᵃᵇ= 4

dᵃc=√((2-2)²+(7-3)²)= 4

dᵇc=√((2-6)²+(7-3)²)=0

a²+b²=c²

4²+4²=32

so it is a right triangle.

9.

A(1,9), B(4,8), C(2,5)

d AB= √((8-4)²+(4-9)²)=√41

d BC=√((2-4)²+(5-8)²)=√13

d AC= √((2-1)²+(5-9)²)=√17

(√17)²+(√13)²=(√41)²

17+13=41

30≠41

so it is not a right triangle.

15.

Add the interior opposite angles together to get the exterior angle:

∠2 = 75+64= 139

17.


24+2x+8=3x+6

2x+32=3x+6

x+6=26

x=20


so the exterior angle is (3*20+6)=66

Exponent Practice:<br> x^2/3=64
docker41 [41]
X^2/3 = 64
x^{2} =64^{3}
x = 64^{3/2}

it is easier to first find square root of 64 and than power it to 3
square root of 64 is 8 which means our equation now looks like:
x = 8^3
now the answer is after powering 8 to 3:
x = 512

:(((( i can't get this one! Please help...
ValentinkaMS [17]

Answer:

  4877 fish

Step-by-step explanation:

Each year, the fish population is multiplied by 1-6% = 0.94, so after 8 years it has been multiplied by 0.94^8 ≈ 0.609569.

At that time, the population is ...

  8000×0.609569 ≈ 4877 . . . fish

Kate, Alexia, and Trina just completed the 400-meter dash at the track meet. Kate finished the race 6 seconds faster than Alexia
Digiron [165]

Answer:

Kate = 52 seconds, Alexia = 58 seconds, Trina = 49 seconds

Step-by-step explanation:

A = K + 6

T = K - 3

K + A + T = 2 min 39 sec or 159 sec

K + (K + 6) + (K - 3) = 159sec

3K + 3 = 159sec

3K = 156sec

K = 52 sec

A = 52 + 6 = 58 sec

T = 52 - 3 = 49 sec
