<h2>
10) What is the base of the triangle?</h2>
From this triangle we know:
<u>THE AREA:</u>
<u>THE HEIGHT:</u>
We know that the area, height, and base of a triangle are related according to the following formula:
Solving B by quadratic formula:
Since we can’t have a negative value of the base, the correct option is:
<h2>11) How long will it take the water balloon to hit the ground?</h2>
We must use the formula:
Since James drops the balloon from a height of 45m, then this is the initial height, so . Moreover, at the very instant he drops the balloon the initial velocity is zero, so . When the ballon hit the ground . Therefore:
Solving this equation:
Rounding to the nearest tenth:
Finally, the water balloon will hit the ground after 2.9 seconds.
<h2>12) Height and initial velocity</h2><h2 />
We have the equation:
But we know that this equation follows the form:
According to this:
The height of the platform is
The initial velocity of the ball is
Answer:
y = 1/2x - 7.5
Step-by-step explanation:
The image below shows proof that the equation y = 1/2x - 7.5 is the line that contains the point (3,-6) and has the slope of 1/2.
Hope this helps! :)
According to the weather station, the temperature was –4 degrees Celsius last night. And today, it is now –10 degrees Celsius.
What was the change in temperature over night?
Answer: 6 degrees Celsius
Solution:
= -4 – (-10)
= -4 + 10
= 6 degrees Celsius
Answer:
The value of the cosine function at 37º is 0.80. A. 0.80
Step-by-step explanation:
The correct statement is: "If the secant of 37º is 1.25, the cosine value to the hundredths degree is:"
Secant and cosine functions are related by the following trigonometric identity:
The value of the cosine function at 37º is 0.80. The right answer is A.
