Using the following triangle, what is the cosine of angle B?

Nikolay [14]

Answer:

cos(B) = a/c

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you that ...

Cos = Adjacent/Hypotenuse

The leg adjacent to angle B is "a". The hypotenuse is "c", so the desired cosine is ...

cos(B) = adjacent/hypotenuse = a/c

Nter the equation of the line in slope-intercept form. Slope is 6, and (1, 3)

kupik [55]

Answer:

The equation in the slope-intercept form will be:

$y=6x-3$

Step-by-step explanation:

Given

slope = m = 6

point = (1, 3)

As we know that the equation of a line in point-slope form is

$y-y_1=m\left(x-x_1\right)$

substituting the values m = 6 and point = (1, 3)

$y-3=6\left(x-1\right)$

Writing the equation in slope-intercept form

$y=mx+b$

where m is the slope, and b is the y-intercept

so the equation of the line in slope-intercept form becomes

$y-3=6\left(x-1\right)$

add 3 to both sides

$y-3+3=6\left(x-1\right)+3$

$y=6x-3$

Therefore, the equation in the slope-intercept form will be:

$y=6x-3$

C an anyone solve this 3(2b + 3)2 = 36 and if so what is it

Natali [406]

$3(2b + 3)^2 = 36$

Divide by 3 on both sides:
$(2b + 3)^2 = 12$

Square root both sides:
$2b + 3= \pm \sqrt{12}$

Take away 3 from both sides:
$2b= \pm \sqrt{12} - 3$

Divide by 2 on both sides:
$b= \dfrac{ \sqrt{12} -3 }{2} \ or \ b= \dfrac{ -\sqrt{12} -3 }{2}$

Answer:
$b= 0.23 \ or \ -3.23$
