The answer is 29
29 is the answer because:
Following PEMDAS
5*6=30
3+30=33
33-4=29
Answer:
Area_lawn = 393.75 π ft^2
Step-by-step explanation:
Maximum radius : 30 feet
Minimum radius: 30 feet - 0.25*(30feet) = 22.5 feet
(25 percent reduction)
To find the area of lawn that can be watered, we just need to calculate the area for the maximum radius and the minimum radius, and then subtract them.
Since the sprinklers have a circular area:
Area = π*radius^2
Max area = π*(30 ft)^2 = 900π ft^2
Min area = π*(22.5 ft)^2 = 506.25π ft^2
Maximum area of lawn that can be watered by the sprinkler:
Area_lawn = Max area - Min area = 900π ft^2 -506.25π ft^2
Area_lawn = 393.75 π ft^2
The roots of x^3 - 7x^2 + 13x - 6 are 0.697, 2 and 4.303
<h3>How to determine the roots?</h3>
The expression is given as:
x^3 - 7x^2 + 13x - 6
Express as a function
f(x) = x^3 - 7x^2 + 13x - 6
Next, we plot the graph of the function f(x) (see attachment)
From the attached graph, we have the zeros to be:
x = 0.697, 2 and 4.303
Hence, the roots of x^3 - 7x^2 + 13x - 6 are 0.697, 2 and 4.303

Answer: First (0-19 home runs) Second (40+ home runs) Thrid (20-39 home runs)
Step-by-step explanation:
Answer:
(x + 2/3)^2 + (y + 3/4)^2 = 5^2 (or 25).
Step-by-step explanation:
Start with the general equation of a circle with center at (h, k) and radius r:
(x - h)^2 + (y - k)^2 = r^2
Substitute -2/3 for h and -3/4 for k, and also 5 for r:
(x - [-2/3])^2 + (y - [-3/4])^2 = 5^2, or
(x + 2/3)^2 + (y + 3/4)^2 = 5^2 (or 25).
