Multiply (3b​ 2​+ 4​b​ + 8)(-2​b​ 2​+ ​b​ + 10).
emmainna [20.7K]
Answer: -30b^2+76b+80
Explanation:
Multiply the second parenthesis by each term from the first parenthesis:
3b•2(-2•2+b+10)+4b•(-2b•2+b+10)+8(-2b•2+b+10)
Then distribute 3b•2 through the parenthesis
-24b^2+6b^2+60b+4b•(-2b•2+b+10)+8(-2b•2+b+10)
Then collect like terms
-30b^2+60b+40b-32b+8b+80
Collect like terms=
-30b+76b+80

The population of Ashmore was 925 in 2000 and in 1028 in 2001. the linear model for ashmores population is p= 103t+925, where th
Sati [7]
Divide known populations:

1028 / 925 = 1.11135

so exponential formula would be 925*1.11135^t

using 15 years:   925 * 1.11135^15 = 4507

linear model: 103(15) +925 = 2470

4507 - 2470 = 2037 more people using exponential

I’m circle R with m angle QRS=82 and QR=16 units find the of arc length of QS. Round to the nearest hundredth
aliina [53]

Answer:

27.92 units

Step-by-step explanation:

Radius (qr) = r = 16 units

<QŘS = θ = 82°

Length of an arc = (Θ / 360) * 2πr

L = (θ / 360) *2πr

L = (82 / 360) * 2π * 16

L = 0.2777 * 100.53

L = 27.917 units

L = 27.92 unit
