Answer:
You need to have both the opposite and adjacent side of the right angled triangle. Tan = Opp/Adj
Step-by-step explanation:
Tangents are pretty much everywhere. A good example is maybe a slide at the playground. You’d need the tangent to figure out the angle of the slide and how it is.
The radius from the center of a circle to the point of tangency point shows that it would be perpendicular to the tangent line considering that anything with a radius is circular and the tangent line is… a line, making it impossible to be parallel.
is it possible to write vector (-5,6) as a linear combination of vectors (1,2) and (3,4)
Answer:
Step-by-step explanation:
-5i+6j=x(1i+2j)+y(3i+4j)
-5=x+3y(multiply by 2)
6=2x+4y
-10=2x+6y
subtract
16=-2y
y=-8
-5=x+3(-8)
x=-5+24=19
-5i+6j=19(i+2j)-8(3i+4j)
so we can write (-5,6) as a linear combination of (1,2) and (3,4)

Divide and simplify the answer to lowest terms. Write the answer as a fraction or a whole number.
17/10 ÷ 11/4
17/10 ÷ 11/4=______?
When you divide by a fraction, flip the second fraction over and change divide to multiply:
17/10 / 11/4 = 17/10 x 4/11
Now multiply straight across:
(17 x 4) / (10 x 11) = 68/110
Simplify:
68/110 = 34/55
Answer: 34/55

why does a week have seven days
Hi!the week has seven days because the Babylonians, who lived in modern-day Iraq, were astute observers and interpreters of the heavens, and it is largely thanks to them that our weeks are seven days long. The reason they adopted the number seven was that they observed seven celestial bodies — the Sun, the Moon, Mercury, Venus, Mars, Jupiter and Saturn.
the main reason is :
Avid astronomers and astrologers, the developed a kind of horoscope around 500 where each day of the week was assigned to one of the classical planets – the seven celestial bodies visible to the eye. These are the Sun, the Moon, Mars, Mercury, Jupiter, Venus, and saturn
susan has a piggy bank with 32 coins in it, all dimes and quarters. She has been collecting state quarters and so far has no repeats. If the piggy bank has $6.20, how many more quarters does Susan need before she has a quarter from each of the 50 states?
Answer:
26
Step-by-step explanation:
First, you need to find how many quarters there are. You can easily try to see the max amount of quarters you can fit. So, 24 quarters.

What is the volume of a cube with an edge length of 7.3 cm?
Enter your answer in the box
Answer:
389.017 cm³
Step-by-step explanation:
Given:
Side length of cube = 7.3 cmThe volume of a cube is the cube of the side length.
V = (side length)³Substitute the side length of the cube to determine the volume of the cube.
⇒ V = (s)³
⇒ V = (7.3)³
⇒ V = (7.3)(7.3)(7.3) = 389.017 cm³
Answer: 389.017

Test help picture below problem 17 18
Step-by-step explanation:
17. 21⁰ + 31⁰ + ?⁰ = 180⁰
= ?⁰ = 128⁰
18. ?² = 12² + 5²
? = √169
? = 13 TYPO
Answer:
17: 128
18: 13
Step-by-step explanation:
17: 21 + 31 = 52, 180 - 52 = 128.
18: a² + b² = c².
5² = 25
12² = 144
25 + 144 = 169
169 square rooted = 13
