A)  average rate=Δy/Δx=(y2-y1)/(x2-x1)=(h2-h1)/(x2-x1)
from x1 = 0 to x2= 1, <span>h(x) = 4^x, h(0)=4^0=1, h(1)=4^1=4
</span>average rate=(h2-h1)/(x2-x1)=(4-1)/(1-0)=3  (section A for interval x=0 to x=1)
from x1 = 2 to x2= 3, h(x) = 4^x, h(0)=4^2=16, h(1)=4^3=64
average rate=(h2-h1)/(x2-x1)=(64-16)/(3-2)=48  (section B for interval x=2 to x=3)
B) av.rate section B/ av. rate section A=48/4=12
this is exponential function, and for Δx=1, Δy change more  for bigger numbers

Which of the following are incorrect expressions for slope?
vfiekz [6]

Answer:

Option B and C are correct.

\frac{x_2-x_1}{y_2-y_1}

\frac{run}{rise} are the expression incorrect for slope

Step-by-step explanation:

Slope is defined as the change in the dependent variable  relative to the change in the dependent variable

or the ratio of the horizontal changes to vertical changes between any two points on the graph of the line.

The vertical changes between any two points is rise

The horizontal changes between any two points is run.

Formula for slope is given by:

For any two points (x_1, y_1) and (x_2, y_2)

then slope is:

\text{Slope} =\frac{rise}{run}= \frac{y_2-y_1}{x_2-x_1}

or we can write this as:

Δy = y_2-y_1

Δx = x_2-x_1

⇒\text{Slope} = \frac{\triangle y}{\triangle x}

Therefore, the expression which are incorrect for slope  are;

\frac{x_2-x_1}{y_2-y_1}

\frac{run}{rise}

When two computers are working together, they can finish updating software in 9 minutes. How long would they take individually t
tensa zangetsu [6.8K]
First computer takes x min. For 1 min it does 1/x part of work.

Second computer takes (x+24) min. For one min it does 1/(x+24) part of work.

Both computers for one min do   (1/x+1/(x+24)) part of work.

At the same time, both computers for one min do 1/9 part of work.

\frac{1}{x} + \frac{1}{x+24} = \frac{1}{9} &#10;\\ \\  \frac{x+24+x}{x(x+24)} =  \frac{1}{9} &#10;\\ \\9(2x+24)=x^{2} +24x&#10;\\ \\ 18x+216=x^{2} +24x&#10;\\ \\ x^{2}+6x-216=0&#10;\\ \\ D=b^{2}-4ac=36+4*216 = 900&#10;\\ \\ x= \frac{-b+/- \sqrt{D} }{2a}  =  \frac{-6+/-30}{2} &#10;\\ \\ x_{1}=-18, x_{2}=12&#10;&#10;We can use only positive number here. So, &#10;&#10;for the first computer x=12 min,&#10;&#10; for second computer x+24=12+24= 36 min&#10;&#10;Answer 12 min and 36 min.

1)The pyramid has a square base that us inscribed in the circular base of the cone. Draw an image of the composite shape of the
DENIUS [597]

Answer:

Diameter of the circle is 8\sqrt{2} units

Step-by-step explanation:

It is given that the vertices of the square fall on the circle.

So, the diagonal of the square is the diameter of the circle.

Also, the diagonal and the two sides of the square form a right angled triangle.

By Pythogoras theorem,

hypotenuse^{2} =side^{2} +side^{2}

= 8^{2} +8^{2}

= 2(8^{2} )

hypotenuse=8\sqrt{2} units

Hence, the diameter of the circle is 8\sqrt{2} units
