find the product of -8 (-12)​

The angles are;

A = 60

B = 38

C = 82

The cosine rule is a mathematical formula used in trigonometry to determine the lengths of sides of a triangle, given the lengths of two sides and the measure of the angle between them. The cosine rule states that the square of the length of a side of a triangle is equal to the sum of the squares of the lengths of the other two sides, minus twice the product of the lengths of those sides and the cosine of the angle between them.

c^2 = a^2 + b^2 - 2abCos C

7^2 = 5^2 + 8^2 - 2(5 *8) Cos C

49 = 25 + 64 - 80 CosC

-40  = -80 CosC

Cos C = 0.5

C = 60°

b^2 = a^2 + c^2 - 2ac Cos B

5^2 = 8^2 + 7^2 - 2(8 *7) Cos B

25 = 64 + 49 - 112Cos B

Cos B = 38

C = 180 - (60 + 38)

A = 82

I hope this helps, if it doesn't then just message me and ill be more than happy to help :)

Answer: X = 20

Steps:

↳ First, I read the question, “Figure A is a scale image of Figure B”.
(Scale image = a smaller image of the original)

  ↳ Then, I divided 12.5 by 10 which was 1.25

       ↳ After that, I multiplied 1.25 by 16 to get 20.

Orleans might have got the answer from subtracting wrong or adding them together.

Hope this helps! :)

Orleans must have chosen C as the correct answer, which is 13/15 hours. This means that Kado spent 13/15 hours longer painting the fence than walking his dog.

To find out how much longer Kado spent painting than walking his dog, we need to calculate the difference between the time he spent painting and the time he spent walking his dog.

Kado spent 1 2/3 hours painting the fence.

He spent 4/5 of an hour walking his dog.

To make the calculation easier, let's convert 1 2/3 hours into an improper fraction:

1 2/3 = (3*1 + 2)/3 = 5/3 hours

Now, the time difference is:

Time spent painting - Time spent walking

= (5/3) - (4/5)

To subtract fractions, we need to find a common denominator, which in this case is 15 (the least common multiple of 3 and 5):

= (5/3)(5/5) - (4/5)(3/3)

= 25/15 - 12/15

Now, we can subtract the fractions:

= (25 - 12)/15

= 13/15 hours

Orleans must have chosen C as the correct answer, which is 13/15 hours. This means that Kado spent 13/15 hours longer painting the fence than walking his dog.

The smallest number is the one closest to zero, or after zero, if it's a negative number, while the largest number is the number with the largest difference from the smallest, or the highest of value (not considering all situations). Usually, you would use the ascending order method for graphing numbers based on their value, which is indeed smallest to largest. According to thefreedictionary.com, "A function or variable continuously approaching zero as a limit." Tip: In ordering numbers based on value, the whole numbers that aren't negative are considerably believed to be the easiest numbers to order.

With that being said, here is the order of the numbers from smallest to largest:

4.38

4.5

4.6

4.9

Answer:

Here are the numbers ordered from closest to zero to farthest from zero:

4.38 (closest to zero)

Answer: 36 inches (in.)

Step-by-step explanation:

The first thing you need to do is form a right triangle from the starting point to the hole to the corner where the ball is at. Right triangles have a hypotenuse (the longest side), and two legs (the shorter sides).

We are told next to the drawing that it’s 39 feet from the staring point to the hole (given a straight line). This is the length of our hypotenuse. We are also given the length of one of the legs, with it being 36 feet.

We need to find the length of the last leg, the length from the ball to the hole. To do this, we can use the Pythagorean Theorem. The Pythagorean Theorem states that the square of each of the legs equals the square of the hypotenuse. The formula for the Pythagorean Theorem is \(a^{2} +b^{2} =c^{2}\), with \(a\) and \(b\) being the legs, and \(c\) representing the hypotenuse.

Input the given values into the formula and you get the following:

\(a^{2} +b^{2} =c^{2}\)
\(36^{2} + x^{2} =39^{2}\)

\(\sqrt{36^{2} } +\sqrt{x^2} =\sqrt{39^2}\)

\(36 +x =39\)

\(x=3\)

Therefore, the length from the ball to the hole is 3 feet (ft.).

BUT WAIT
The question asks us to provide our answer in inches (in.), and 1 foot equals 12 inches.

Therefore, the distance from the ball to the hole is 36 inches (in.).

To estimate the volume using the Midpoint Rule with \(\displaystyle n=5\), we need to divide the interval \(\displaystyle 0\leq x\leq 1\) into \(\displaystyle n\) subintervals of equal width. Since \(\displaystyle n=5\), each subinterval will have a width of \(\displaystyle \Delta x=\frac{1-0}{5}=\frac{1}{5}\).

Now, let's calculate the volume using the Midpoint Rule. The formula for the volume obtained by rotating about the y-axis is:

\(\displaystyle V\approx 2\pi \sum _{i=1}^{n}y_{i}\Delta x\)

where \(\displaystyle y_{i}\) represents the value of the function \(\displaystyle y=\sqrt{1+x^{3}}\) evaluated at the midpoint of each subinterval.

First, let's find the midpoints of the subintervals. Since the width of each subinterval is \(\displaystyle \Delta x=\frac{1}{5}\), the midpoint of the \(\displaystyle i\)-th subinterval is given by:

\(\displaystyle x_{i}=\frac{\Delta x}{2}+\left( i-\frac{1}{2}\right) \Delta x=\frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\)

Substituting \(\displaystyle x_{i}\) into the function \(\displaystyle y=\sqrt{1+x^{3}}\), we obtain:

\(\displaystyle y_{i}=\sqrt{1+\left( \frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\right) ^{3}}\)

Now, we can calculate the approximate volume using the Midpoint Rule:

\(\displaystyle V\approx 2\pi \sum _{i=1}^{5}y_{i}\Delta x\)

Substituting the values of \(\displaystyle y_{i}\) and \(\displaystyle \Delta x\) into the formula, we can evaluate the sum and compute the estimated volume.

Step-by-step explanation:

On the graph the y coordinate 70 intersects  with the x coordinate 1 on the line. So, train B is traveling at 70x, they tell us train A is moving at 74x which is higher up and therefore would have a steeper line. Meaning it would be traveling at a faster rate.

Answer:

The sum of two consecutive number is 55'which is the largest number? So the numbers are 27 and 28.

Step-by-step explanation:

If we say \(x\) is the first number, then the next consecutive number will be \(x+1\).

Using this, we can make an equation.

\(x+(x+1)=55\)

\(2x+1=55\)

\(2x=54\)

\(x=27\)

And so we know that the two consecutive numbers are 27 and 28.

Hope this helps.
