Answer:

y=2x+5

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(9-(-1))/(2-(-3))

m=(9+1)/(2+3)

m=10/5

m=2

y-y1=m(x-x1)

y-(-1)=2(x-(-3))

y+1=2(x+3)

y=2x+6-1

y=2x+5

if a cylinder with height 9 inches and radius r is filled with water, it can fill a certain pitcher. how many of these pitchers

dalvyx [7]

Answer:

4 pitchers

Step-by-step explanation:

we know that

The volume of a cylinder is equal to

$V=\pi r^{2}h$

step 1

Find the volume of the cylinder with height 9 inches and radius r

substitute the given values

$V_1=\pi r^{2}(9)$

$V_1=9\pi r^{2}\ in^3$

step 2

Find the volume of the cylinder with height 9 inches and radius 2r

substitute the given values

$V_2=\pi (2r)^{2}(9)$

$V_2=36\pi r^{2}\ in^3$

step 3

we know that

The volume of the cylinder 1 can fill a certain pitcher,

The volume of the pitcher is the same that the volume of cylinder 1

therefore

the number of pitchers that can be filled by the second cylinder is equal to divide the volume of the second cylinder by the volume of the first cylinder

$\frac{36\pi r^{2}}{9\pi r^{2}}=4\ pitchers$

gross income £12000 tax free allowance £6475 what is taxable amount @20%, tax payable,net income and weekly net amount how to wo

olganol [36]

We calculate for the taxable income by subtracting the tax free allowance from the gross income.

Taxable income = Gross income - tax free allowanc
Taxable income = (£12,000 - £6,475)
= £5,525

Hence, the taxable income is equal to £5,525.

Net income:
This would be equal to the gross income minus the amount of taxes to be paid.

Net income = Gross income - amount of tax to be paid
Net income = (£12,000) - (0.20)($5,525)
Net income = $10,895

Therefore,
ANSWER: $10,895
