Answer:

Step-by-step explanation:

f(x)=-4x+2

g(x)=x²+1

(gof)(x)=g(f(x))=g(-4x+2)=(-4x+2)²+2=16x²-16x+4+2=16x²-16x+6

(gof)(3)=16(3)²-16(3)+6=144-48+6=150-48=102

What is the average rate of change of the function on the interval from x = 0 to x = 5?

crimeas [40]

Answer:

Average rate of change $=\frac{1}{8}$

Step-by-step explanation:

Given interval are from $x=0\ to\ x=5$

Also, $=\frac{1}{2^3}x=\frac{1}{8}x$

Average rate of change $=\frac{f(b)-f(a)}{b-a}\ for\ given\ interval\ [a,b]$

Here given intervals are $a=0\ and\ b=5$

Plugging these value in formula, we get.

Average rate of change $=\frac{\frac{1}{8}(5)-\frac{1}{8}(0)}{5-0}\\\\=\frac{\frac{1}{8}(5)-0}{5-0}\\ \\=\frac{\frac{1}{8}(5)}{5}\\\\=\frac{1}{8}$

Help pls

babymother [125]

Answer:

1). x = 10 m

2). x = 15 cm

3). x = 5 yd

4). AB = 10 units

Step-by-step explanation:

1). By Pythagoras theorem in the given triangle,

a² + b² = c²

Where 'c' = Hypotenuse

a and b = Legs of the right triangle

By substituting measures of the sides in the formula,

x² = 8² + 6²

x = $\sqrt{100}$

x = 10 m

2). By using Pythagoras theorem in this triangle,

x² = 9² + (12)²

x² = 81 + 144

x = $\sqrt{225}$

x = 15 cm

3). By Pythagoras theorem,

(13)² = x² + (12)²

169 = x² + 144

169 - 144 = x²

25 = x²

x = 5 yd

4). If BD is a perpendicular bisector of AC,

AD = CD = 6 cm

By Pythagoras theorem in ΔABD,

AB² = BD² + AD²

AB² = 8² + 6²

AB = $\sqrt{100}$

AB = 10 units
