We have f(1) = -1.5;
f(2) = -2f(1), because we put n=1 in formula f(n+1)=-2f(n);
Answer:
A. -50 feet
Step-by-step explanation:
To find the number closest to sea level, take the absolute value of each number and see which is closest to zero.
A. -50 feet abs (-50) = 50
B. -68 feet abs (-68) = 68
C. -77 feet abs (-77) = 77
D. -86 feet abs ( -86) = 86
E. -97 feet abs (-97) = 97
The smallest number is 50. -50 ft is closest to sea level
The only equation that can produce a loop at the bottom is the one that has opposite sign non-zero values for r at π/2 and 3π/2. The last selection meets that requirement.
r = 1 + 3 sin(θ)
Dimensions of the room------------------- >16*13
1 in---------------- >0.0833333 foot
3 in----------------- >x
x=3*.0833333=0.25 ft
Let
<span>C-------------- > dimensions of the piece of carpet that Charlotte must purchase
C-------------- > (16+2*0.25)*(13+2*0.25)---------- > (16.50)*(13.50)=222.75 ft</span>²
<span>
The answer a the question 1) is 16.50 feet X 13.50 feet</span>
The answer a the question 2) is 222.75 ft²
<span>3. How many hours should it take for the four-person crew to lay the flooring in Charlotte's bedroom?
if </span><span>two-person carpet crew can lay 50 square feet of carpet---------- > 1 hour</span><span>
four person </span>carpet crew can lay 100 square feet of carpet---------- > 1 hour
therefore
if 100 ft² carpet----------------------- > 1 hour
222.75 ft² carpet--------------------- > x
x=222.75/100=2.2275 hours=2.23 hours
The answer is 2.23 hours
Answer:
r = 10q/(p + 30)
so put p+30 in the blank
Step-by-step explanation:
p=10(q - 3r)/r
p = (10q - 30r)/r
pr = 10q - 30r
pr + 30r = 10q
r(p + 30) = 10q
r = 10q/(p + 30)
