Answer:
1.863×10^5 miles/second
Step-by-step explanation:
There are 3600 seconds in 1 hour, so the distance traveled in 1 second will be 1/3600 times the distance traveled in 1 hour:
6.706×10^8/(3.6×10^3) ≈ 1.863×10^5 . . . . miles/second
Answer:
54.314 °
Step-by-step explanation:
It is given that in triangle ABC, AB = AC = 6m. So, it is an isosceles triangle
Now, it is also given that BC = 7 cm.
We have to find the value of angle C.
If we draw a perpendicular on BC from point A, then it will bisect BC at D i.e. AD is a perpendicular bisector of BC.
Now, the triangle ADC is a right triangle in which, the base DC =7/2 =3.5 cm and hypotenuse AC = 6m (Given) and angle ADC= 90°.
Therefore, Cos∠C = DC/AC =3.5/6.
⇒ ∠C =Cos⁻¹ (3.5/6) =54.314 ° (Answer)

Answer:=530
Step-by-step explanation:
Answer:
i think its -3
Step-by-step explanation:
Because any number raised to the power of 0 is 1 or -1.
so itll be (-1) + (-1) × 2 =
-1 + (-2) = -1 -2 = -3
