Answer:

4. Cos y= b/6

Step-by-step explanation:

sin = Opp. / Hypo.

cos = Adj. / Hypo

tan = Opp. / Adj.

If y = a/6 and tan y = a/b --> Opp. = a, Hypo. = 6, and Adj. = b

so

cos y = Adj. / Hypo = b/6

Answer:

4. Cos y= b/6

Which expression Is equivalent to x^2+10x+24
garik1379 [7]

Answer:

(x+4)(x+6)

Step-by-step explanation:

First we factorise:

x²+4x+6x+24

x(x+4)+6(x+4)

(x+4)(x+6)

So the last one is equivalent

Answer:

Area of larger circle = \pi *r^2=3.14(11^2)=379.94

Area of smaller circle = \pi *r^2=3.14(3^2)=28.26

Probability that it lands in the shaded area (smaller circle):

28.26 ÷ 379.94 = 0.07438... = 0.07 (nearest hundredth)

Write the equation of the line that passes through (-6,0) and is parallel to the line y=5x-43
AVprozaik [17]

The equation of the line that passes through (-6,0) and is parallel to the line y = 5x - 43 in slope intercept is y = 5x + 30

<em><u>Solution:</u></em>

Given that line that passes through (-6, 0) and is parallel to the line y = 5x - 43

We have to find the equation of line

Let us first find slope of line having equation y = 5x - 43

<em><u>The slope intercept form of line is given as:</u></em>

y = mx + c  ------- eqn 1

Where "m" is the slope of line and "c" is the y - intercept

On comparing equation of line y = 5x - 43 with slope intercept form y = mx + c,

we get m = 5

Thus slope of given line is 5

We know that slopes of parallel lines are equal

Thus the slope of line parallel to given line is also 5

Now let us find equation of line having slope "5" and passes through (-6, 0)

Substitute m = 5 and (x, y) = (-6, 0) in eqn 1

y = mx + c

0 = 5(-6) + c

<h3>c = 30</h3>

<em><u>Thus the required equation is:</u></em>

Substitute c = 30 and m = 5 in eqn 1

y = 5x + 30

Thus the required equation of line is found
