What is the slope of the line that passes through points (2,-3) and (5,1)

Ivenika [448]

Find the difference in the y-coordinates: -3 - 1 = -4

Find the difference in the x-coordinates in the same order: 2 - 5 = -3

Divide the difference in y by the difference in x: slope = (-4)/(-3)

Reduce the fraction: slope = 4/3

How many 1/5 liter glasses can Lin fill with a 1 1/2 liter bottle of water?

RoseWind [281]

Answer:

The number of 1/5 liter glasses that Lin can fill is $7\frac{1}{2}$

Step-by-step explanation:

we know that

To find out how many 1/5 liter glasses can Lin fill with a 1 1/2 liter bottle of water, divided 1 1/2 by 1/5

$1\frac{1}{2} :\frac{1}{5}$

Convert mixed number to an improper fraction

$1\frac{1}{2}=1+\frac{1}{2}=1\frac{1*2+1}{2}=\frac{3}{2}$

substitute

$\frac{3}{2} :\frac{1}{5}$

Multiply in cross

$\frac{5*3}{2*1}=\frac{15}{2}=7.5$

Convert to mixed number

$7.5=7+\frac{1}{2}=7\frac{1}{2}$

Cos(x)= 40/41 and x lies in Q4. Find sin(x)

notka56 [123]

Step-by-step explanation:

$\sin(x) = \sqrt{1 - {cos}^{2}x }$

$\sin(x ) = \sqrt{1 - { (\frac{40}{41} )}^{2} }$

$\sin(x) = \sqrt{ \frac{1681 - 1600}{1681} } = \sqrt{ \frac{81}{1681} }$

sin(x)=±9/41

As x lies in Quadrant 4 , sin(x) = -9/41
