Find the cosine ratio of angle Θ. Clue: Use the slash symbol ( / ) to represent the fraction bar, and enter the fraction with no

spaces. Triangle ABC is shown. AB measures 4. BC measures 5. CA measures 3. The angle formed at point C is marked theta, and angle A is the right angle.

Answer:

Cosθ = 3/5

Step-by-step explanation:

Given:

In ∆ ABC.

AB measures = 4

BC measures = 5

CA measures = 3

The angle formed at point C is marked theta

angle A is the right angle

Find attached the diagram from the given information.

We are to find the cosine ratio. To do this, we would apply SOHCAHTOA in trigonometry

Sine ratio: Sinθ = opposite /hypotenuse

Cosine ratio: Cosθ = adjacent/hypotenuse

Tangent ratio: Tanθ = opposite/adjacent

From the diagram,

adjacent = AC

hypotenuse = BC

Using the above formula,

Cosθ = adjacent/hypotenuse = AC/BC

Cosθ = 3/5

Find the equation of the line in slope-intercept form containing the points (6, -1) and (-3, 2).
egoroff_w [7]
Slope intercepf is y=mx+b wherem=slope and b= y intercept
slope is found by doing
(y1-y2)/(x1-x2)
points are (6,-1) and (-3,2)
(x,y)
x1=6
y1=-1
x2=-3
y2=2
subsitute
(-1-2)/(6-(-2))=-3/(6+2)=-3/8
slope=-3/8
subsitute
y=-3/8x+b
subsitute and solve for b
(-3,2)
x=-3
y=2
2=-3/8(-3)+b
2=9/8+b
2=16/8
subtract 9/8 from both sides
16/8-9/8=b
7/8=b
y=-3/9x+7/8 is the equation

0.000626 L is the same as 6.26 cm3. <br> a. True<br> b. False
Elan Coil [88]
One litre is equivalent to 1000 centimetres cubed.

0.000626 x 1000 = 0.626

Therefore, it is b) or false.

Find the median mode range and any outliers. Then describe the data using them 77777,88,555,6,99,10101010,12
umka2103 [35]

Answer:

The median = 5

The mode  = 7

Range = 5

Outliers= None

Step-by-step explanation:

The median is the  value of the middle term.

The median is that value which divides the data into two equal halves.

7,7,7,7,7,8,8,5,5,5,6,9,9,10,10,10,10,12

There are 18 terms . So the middle term would be 9th term value= 5

The mode is the value which is repeated the most. = 7

Range is the difference between the highest and lowest value.= 12- 7= 5

The interquartile range, IQR= q3 - q1 where q3= 10 and q1= 7

IQR= 10 −7=3

The inner fences can be found out by

q1−(1.5*IQR) and q3+(1.5*IQR)

=7−(1.5*3) and 10+(1.5*3)

Inner fences: 2.5 and 14.5

The outer fences are q1−(3*IQR) and q3+(3*IQR)

=7−(3*3) and 10+(3*3)

Outer fences: -2 and 19

So if there are any outliers in this data set, they will either be less than -2 or greater than 19. But there are no outliers.

Complete the equation of the graphed linear function. Write the slope in decimal form.
erma4kov [3.2K]

Every straight line graph has an equation in the same form:

             y  =  (slope of the line) x  +  (y-intercept) .


-- The slope of the line is

     (how far it goes UP, going left to right between any 2 points)
divided by
     (how far it goes left to right between the same 2 points) .

The line on this graph has a slope of  + 1/2 .


-- The y-intercept is the point where the line crosses the y-axis.
The line on this graph crosses the y-axis at  -1 .

                       y  =  (slope of the line) x  +  (y-intercept) .                     

                       y  =      ( 0.5 ) x                            ( - 1 ) .
