You can read the slope of the line directly from the graph:

m = rise/run = 1/1 = 1.  Also easily visible is the y-intercept, b = 1.

Thus, this linear function has the equation f(x) = x + 1.

Simplify: 4^ sqrt 400/ 4^ sqrt 5 <br> SHOW WORK
USPshnik [31]

Given  

The equation is in the form

=\frac{4^{\sqrt{400}}}{4^{\sqrt{5}}}

Simplify the above equation

To proof

As given in the question the equation is written in the form

=\frac{4^{\sqrt{400}}}{4^{\sqrt{5}}}

By using the exponent property

when you divide powers with the same base you just have to subtract the exponents. i.e

\frac{y^{a}}{y^{b}} = y^{a-b}

y is not equal to zero.

Now apply this property to the above equation

=4^{\sqrt{400}- \sqrt{5}}

As

\sqrt{400} = 20

now put this in the above equation

we get

=4^{20- \sqrt{5}}

Hence proved

A line passes through the points (2,21) and (8,27). Write a linear function rule in terms of x and y for
tatiyna
We have two points so we can find the gradient using y1-y2/x1-x2
gradient = 21-27/2-8
= 1
we know the form for any linear equation is y = mx + c
we have m and a point so we can substitute in point (2,21) to find c
21 = 1 x 2 + c
c = 19
therefore, the equation is y = x + 19

Help me with this please
bekas [8.4K]

Answer:

f(-5) = 4(-5) + 1 = -20 + 1 = -19

f(-1) = 4(-1) + 1 = -4 + 1 = -3

f(2) = 4(2) + 1 = 8 + 1 = 9

f(3) = 4(3) + 1 = 12 + 1 = 13

f(5) = 4(5) + 1 = 20 + 1 = 21

If 3/4 of an inch of rain fell in 1/2 hour, explain how to get the unit rate
bearhunter [10]

Answer:

Search to find the detailed rainfall collections if you want more detailed rainfall intensity data. If all available is monthly average in mm, take the monthly average and divide by number of hours in that month. So if you had 300 mm in April, take 360 mm/(30 days * 24 hours) = 0.5 mm/hour average monthly intensity. so that's it
