Answer:

45 miles

Step-by-step explanation:

Let, the friend's village from Lucas' house is x miles away.

Now, It takes Lucas 3 hours to cycle from his home to his friend's village. But if he travels 5 mph slower, it will take him 1.5 hours longer.

So, we can write

$\frac{x}{\frac{x}{3} - 5} = 3 + 1.5 = 4.5$

⇒ x = 1.5x - 22.5

⇒ 0.5x = 22.5

⇒ x = 45 miles (Answer)

In ΔSTU, s = 6.1 cm, t = 3.2 cm and u=7.4 cm. Find the measure of ∠S to the nearest 10th of a degree.

GuDViN [60]

Answer:

m∠S = 54.1°

Step-by-step explanation:

Use the law of cosines

$s^{2} = t^{2} + u^{2} - 2utcos S\\6.1^{2} = 3.2^{2} + 7.4^{2} - 2(3.2)(7.4) cos S$

37.21 = 10.24 + 54.76 - 47.36 cos S

-27.79 = -47.36 cos S

.586782 = cos S

arccos .586782 = S

m∠S = 54.1°

We want to factor the following expression: 25x^2−36y^8 We can factor the expression as (U+V)(U-V) where U and V are either cons

Aneli [31]

Answer:

$U=5\,x$

$V=6\,y^4$

Step-by-step explanation:

Recall that an expression that can be factored as (U+V)(U-V) using distributive property for multiplication of binomials, should render: $U^2-V^2$ (the factorization given above is that of a difference of squares. Then, the idea is to write the original expression :
