Answer:
44 square units
Step-by-step explanation:
The area of the 2 upper triangles is:
2 * ((1/2) * b * h) = 2 * ( (1/2) * 4 * 3) = 2 * 6 = 12
The area of the rectangle in the middle of the figure is:
b * h = 8 * 3 = 24
The area of the lower triangle is:
1/2 * b * h = 1/2 * 2 * 8 = 8
The area of the composite figure is:
Area of the 2 upper triangles + area of the rectangle + the area of the lower triangle = 12 + 24 + 8 = 44 square units (area is always given in square units)
Answer:
25 months
Step-by-step explanation:
We can use the amortization formula to solve for t.
That formula tells you the monthly payment as a function of interest rate (r=.14), compounding periods per year (n=12), principal borrowed (P=4200), and number of years (t). Using the given values, we have ...
200 = 4200(r/n)/(1 -(1 +r/n)^(-nt))
1 -(1 +r/n)^(-nt) = 4200(r/n)/200
1 -21r/n = (1 +r/n)^(-nt)
log(1 -21r/n) = -nt·log(1 +r/n)
-log(1 -21r/n)/log(1 +r/n) = nt . . . . . . the number of months we want
-log(1 -21(0.14)/12)/log(1 +0.14/12) = nt = 24.23
It will take Daisy about 25 months to pay of her credit card.
Answer: −50x−66
Step-by-step explanation:
4(10x+6)−10(9x+9)
Distribute:
=(4)(10x)+(4)(6)+(−10)(9x)+(−10)(9)
=40x+24+−90x+−90
Combine Like Terms:
=40x+24+−90x+−90
=(40x+−90x)+(24+−90)
=−50x+−66
Answer:
y=-5/2x-18
Step-by-step explanation:
use the y=mx+b method
plug in -8 for "x" and 2 for "y" and plug in -5/2 for "m"
2=-5/2(-8)+b
multiply -5/2 and -8
2=20+b
subtract 20 on both sides
-18=b (b=ur y-intercept)
ik this dont make any sense but hope this helps
