Answer:

y = -5x + 6

Step-by-step explanation:

To find the slope of a line you have to use the following formula:

y2 - y1 / x2 - x1

choose any 2 rows for "x" and "y" (it doesn't matter), but "x" and "y" have to come from the same row. (I'll do the third and fourth rows)

x1 = 1

y1 = 1

x2 = 2

y2 = -4

(-4 - 1) / (2 - 1)

-5 / 1

slope (m) = -5

the equation of a line is y = mx + b

m = slope

b = y-intercept

pick any row to plug "x" and "y" into the equation so you can find "b" (I'll choose row three); you already know the slope (m)

1 = -5(1) + b

1 = -5 + b

b = 1 + 5

b = 6

plug everything in to the equation y = mx + b

equation: y = -5x + 6

A vase in the shape of an oblique cylinder has the dimensions shown. What is the volume in the vase in liters?round nearest tent

dlinn [17]

The volume of a vase with a radius of 1 m and height of 7 m is 22000 L

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

Cylinder is solid geometrical figure with straight parallel sides and a circular or oval cross section

Let us assume that the vase has a base with radius of 1 m and height of 7 m, hence:

Volume of vase = π * radius² * height

Volume of vase = π * (1)² * 7 = 22 m³ = 22000 L

The volume of a vase with a radius of 1 m and height of 7 m is 22000 L

Solve the equation 3tan(2x+15°)=4 for 0°is less than equal to x and 180° is greater than equal to x.

Vlada [557]

Answer:

$3tan(2x+15)=4\\or, \frac{tan2x+tan15}{1-tan2x.tan15} =\frac{4}{3}\\or, 3tan2x+3tan15=4-4tan2x.tan15 \\or, 3tan2x+4tan2x.tan15=4-3tan15\\or, tan2x(3+4tan15) = 4-3tan15\\or, tan2x = \frac{4-3tan15}{3+4tan15}\\or, 2x =tan^{-1}(\frac{4-3tan15}{3+4tan15})\\or, x = \frac{tan^{-1}(\frac{4-3tan15}{3+4tan15})}{2} = 19.06505118 (approximate)\\$ $Note: tan30 = \frac{2tan15}{1-tan^{2}15}\\or, \frac{1}{\sqrt{3} } = \frac{2tan15}{1-tan^{2}15}\\or, 1-tan^{2}15 = 2\sqrt{3}tan15\\or, tan^{2}15+2\sqrt{3}tan15-1=0\\Solve~using~the~quadratic~formula~to~get~tan15^o=2-\sqrt{3}.$
