Answer:
6 pounds of fertilizers are needed for garden area of 180 square foot.
Step-by-step explanation:
Let 'x' pounds of fertilizers be needed for 180 square foot garden.
Given:
4 pounds of fertilizer needed for an area of 120 square foot.
The area of the garden given is 180 square foot.
Now, as per question:
4 pounds of fertilizer is equivalent to an area of 120 square foot.
Therefore, 'x' pounds of fertilizer is equivalent to an area of 180 square foot.
Applying proportion and cross multiplying method, we get:
x 4
_ = _
180 120
120x=4 x 180
120x= 720
x = 720
_
120
x=6 LBS
Therefore, 6 pounds of fertilizers are needed for garden area of 180 square foot.
Step-by-step explanation:
number 1 is wrong instead of 15 its 25, number 2 is correct.
Answer: The answer is A. It is located at -25 and is to the right of point A on the number line.
Step-by-step explanation:
On a number line, the number ZERO is in the middle. The positive numbers increase to the right meanwhile the negative numbers increase to the left.
For this case we have the following function:
When evaluating x = 2 in the given function we have:
Rewriting we have:
Therefore, the pair ordered for this point is given by:
The ordered pair of the table for x = 2 is:
Therefore, the table is incorrect for x = 2
Answer:
The row in the table is incorrect for:
x=2
Answer:
B. a(t) = -3π²cos(πt)
Step-by-step explanation:
Acceleration is the second derivative of the position. Here, the second derivative of the cosine function is ...
d²(cos(πt))/dt²= -π²cos(πt)
Of course, the second derivative of the constant is zero. When we consider the multiplier of 3, we have ...
a(t) = x''(t) = -3π²cos(πt) . . . . . . . matches choice B
