It all depends on how the equation is written.
For this case you can see the problem like a triangle with a right angle (90 degrees), an angle of 45 degrees and a hypotenuse of 100 feet.
Then, the vertical height above the point where the rope is held is
y = 100 * sin (45) = 70.71 ft
The answer is
the kite vertically above the point at which the string is being held is 70.71 ft high
Answer:
- A. A neutrally-charged carbon atom contains 6 positively-charged protons and 6 negatively-charged electrons. CORRECT
- B. The average temperature in Cleveland, Ohio in December is 38∘F. On a particularly cold day last year, the temperature change was −38∘F from the previous day. CORRECT
- C. A model rocket flies 50 meters into the air. It falls 50 meters before it hits the ground. CORRECT
- D. The price of gold is $3.00 per ounce less than it was yesterday. WRONG
Explanation:
The <em>additive inverse property</em> is the property that states that the addtiion of a number with its negative is zero: b + (-b) = 0.
Let's see every choice:
- A. A neutrally-charged carbon atom contains 6 positively-charged protons and 6 negatively-charged electrons. CORRECT
6 positively'charged protons ⇒ charge +6
6 negatively charged electrons ⇒ charge -6
Total charge = +6 + (-6) = 0
The result is that the atom has a zero net charge.
- B. The average temperature in Cleveland, Ohio in December is 38°F. On a particularly cold day last year, the temperature change was −38°F from the previous day. CORRECT
Temperature of a day is 38° F
Change of temperature was - 38° F
Resulting temperature: 38° F + ( -38° F) = 0
- C. A model rocket flies 50 meters into the air. It falls 50 meters before it hits the ground. CORRECT
50 meters upward ⇒ +50 m
50 meters downward ⇒ -50 m
Final altitude = +50 m + (-50 m) = 0
- D. The price of gold is $3.00 per ounce less than it was yesterday. WRONG
Price of yesterday : x
Price of today: x - 3.00
This is not the application of the additive inverse property.
Step-by-step explanation:
Solution,
- principle=4500
- Time=3 years
- Rate of interest=5%
- Simple Interest=?
Simple Interest=
Hence, the simple Interest is 675.
