3. The length of the hypotenuse of a right triangle is 12 yards. Theother two sides are equal in length. Find the length of each side to the
nearest tenth of a yard.

Answers

Answer: The other two sides measure 8.5 yards each

Step-by-step explanation: The triangle is a right angled triangle with the other two sides of equal measurement. What this means is that, one angle measures 90 degrees and the other two angles would be of equal measurement. The reason being that we have an isosceles triangle and one property of an isosceles triangle is that two sides are equal and two angles are equal. If one angle measures 90, then the other two would be measured as

(180 - 90)/2 and this equals

90/2 and that equals 45 degrees each. To calculate the length of the equal sides, we use the trigonometric ratio of sine.

(Let one of the unknown sides be A)

Sin 45 = opposite/hypotenuse

Sin 45 = A/12

By cross multiplication we now have

Sin 45 x 12 = A

0.7071 x 12 =A

8.4852 = A

To the nearest tenth

A = 8.5 yards

This means the other equal side would measure 8.5 yards as well.

Given the functions below, what is f(x)−g(x) ?f(x)=7x3−10x2−5g(x)=2x3+7x2−9
A
5x3−17x2+4

B
5x3−3x2−14

C
9x3−3x2−14

D
5x3−17x2−14

Answers

Answer:

f(x)-g(x)=5x^3-17x^2+4 which appears as option A

Step-by-step explanation:

Simply subtract the function's expressions as shown below, and combine like terms to express the final result:

$f(x)=7x^3-10x^2-5\ng(x)=2x^3+7x^2-9\nf(x)-g(x)=7x^3-10x^2-5-[2x^3+7x^2-9]\nf(x)-g(x)=7x^3-10x^2-5-2x^3-7x^2+9\nf(x)-g(x)=7x^3-2x^3-10x^2-7x^2-5+9\nf(x)-g(x)=5x^3-17x^2+4$

Chad buys peanuts in 2 pounds bags. He repackages them into bags that hold 5/6 pound of peanuts. How many 2 pound bags of peanuts should Chad buy so that he can fill the 5/6 pound bags without having any peanuts left over?

Answers

think about it this way, that for every 5/6 pound bag you are losing 1/6 and 1/6*12=2 therefore the answer is 12
