Talia took the bus from her home to the bank and then walked back to her home along the same route. The bus traveled at an avera

ge speed of 40 km/h and she walked at an average speed of 5 km/h. To determine the time, x, that it took Talia to walk home, she used the equation 40(0.9 – x) = 5x.

Since the equation is already given, as well as the average speed of both the bus and her walk, we can just simply solve for x, which is the time.


40(0.9-x) = 5x


36-40x = 5x


36 = 5x + 40x


36 = 45x < divide both sides by 45 so the result would be:


x = 0.8


Therefore, it took Talia 0.8 hour to walk home or 48 minutes.


Please correct me if I'm wrong!! :)

Can a right triangle be isosceles? Use the Pythagorean Theorem to explain why or why not.
PilotLPTM [1.2K]

Answer:

Yes

Step-by-step explanation:

Isosceles triangles have two equal sides, meaning that there are also two equal internal angles. One of the basic triangles other than the 30-60-90 one is the 45-45-90 triangle, so yes an isosceles right angle is possible.

Find the first 4 terms in the expansion of ( 1 + x 2 ) 8. Use your answer to find the value of ( 1.01 ) 8
anyanavicka [17]

(1+x^2)^8

=(1+8x^2+8*7/(1*2)x^4+8*7*6/(1*2*3)x^6+8*7*6*5/(1*2*3*4)x^8+....)

=1+8x^2+28x^4+56x^6+70x^8+....)

For x<1, higher power terms diminish in value, hence we can approximate powers of numbers.

1.01=(1+0.1^2) => x=0.1 in the above expansion

(1.01)^8

=1+8(0.1^2)+28(0.1^4)+56(0.1^6) [ limited to four terms, as requested]

=1+0.08+0.0028+0.000056 (+0.00000070)

=1.082856 (approximately)
