<span>Area of circular metal=πr^2
=3.14 x 3.5 x 3.5 m^2
now,
total cost=area x rate
=3.14 x 3.5 x 3.5 x 3.25 $
=125.01 $</span>
Answer:
the measure of the exterior angle is 87 degrees.
Primero que bada ubicas las coordenadas de los puntos extremos para despues asi aplicando la siguiente formula encuentres su pendiente al igual que su angulo de inclinacion las formuas son m=X2-X1÷Y2-Y1 y angulo teta = Inv.Tan.teta la segunda formula es de la pendiente y la otra del angulo de inclinacion o teta
To get a proper result we have to take into consideration order of operation.
2{3[9+4(7-5)-4]}=2{3[9+4*2-4]}=2{3[9+8-4]}=2{3*13}=2*39=78 - its the answer
Step-by-step explanation:
if the 2 matrices are inverse, then their product must be the identity matrix
1 0
0 1
so,
m×3 + 2×-7 = 1
7×3 + 3×-7 = 0
m×-2 + 2×m = 0
7×-2 + 3×m = 1
that means we have to solve only
3m - 14 = 1
3m = 15
m = 5
