Answer:

4 5/8 the answer you have is correct :)

Step-by-step explanation:

First, you want to make the mixed fraction into an improper fraction.

7 x 4 + 3 = 31 (31/4)

3 x 8 + 1 = 25 (25/8)

Now you want them both to have a common denominator.

31/4 x 2/2 = 62/8

Now you are ready to subtract!

62/8 - 25/8 = 37/8

Finally, convert 37/8 to a proper fraction.

37/8 = 4 5/8

The lengths of the sides of a triangle are consecutive integers, and the largest angle is twice the smallest angle. What is the

hjlf

Answer: $cosA = \frac{a+2}{2a}$

Step-by-step explanation:

Given that the lengths of the sides of a triangle are consecutive integers

Since side cannot be negative we can assume that the sides are

a, a+1 and a+2 where a>0

The largest angle is opposite side a+2 and smallest is angle opposite a

Using sine formula and the given information that the largest angle is twice the smallest angle

we get

$\frac{a}{sin A} =\frac{a+2}{sin 2A}$

Cross multiply to get

$\frac{sin 2A}{sin A } =\frac{a+2}{a}$

Since sin 2A = 2sin A cos A

we get

$2cosA = \frac{a+2}{a} \\cosA = \frac{a+2}{2a}$

f(1)=−8 f(n)=f(n−1)−3 Find an explicit formula for f(n)

Nat2105 [25]

Answer:

f(n) = -8 -3(n -1)

Step-by-step explanation:

The given recursive formula tells you that the difference between two sequential terms is -3, and that the first term is -8. This is a formula for an arithmetic sequence, so we can use the explicit formula ...

f(n) = a1 +d(n -1)

for a1 = -8 and d = -3.

f(n) = -8 -3(n -1)
