I have no idea how to do this, it is due in two days. Hopefully someone sees this before then.

Hello,

$m\ \widehat{ABC}=x\\m\ \widehat{BAC}=2*x\\\\So:\\ x+2x=90^o\\x=30^o\\$

$cos(30^o)=\dfrac{\sqrt{3} }{2} \\$

In the triangle ABC,

$cos(30^o)=\frac{BC}{BA} \\\\BA=\dfrac{cos(30^o)}{BC} \\\\BA=\frac{\dfrac{\sqrt{3} }{2} }{24} =16*\sqrt{3} \\\\$

$sin(30^o)=\dfrac{1 }{2} =\dfrac{AC}{AB} \\\\AC=\dfrac{1}{2} *16\sqrt{3} =8\sqrt{3}$

In the triangle ACB,

$cos(30^o)=\dfrac{AC}{AL} \\\\AL=\dfrac{8\sqrt{3} *2}{\sqrt{3} } =16\\$

A cone has a radius of 3 and a height given by the expression 2a. Which expression represents the volume of the cone?

DiKsa [7]

V=(1/3)hπr^2 where h=height and r=radius
given
radius=3
height=2a

r=3
h=2a

v=(1/3)hπr^2
v=(1/3)(2a)π(3)^2
v=(1/3)2aπ9
v=6aπ

so the expression would be some variaant of v=6aπ

Write an equation of a line that is parallel to y=-3x+5 that passes through the point (0,-4)

elena55 [62]

Answer:

${ \rm{y = - 3x + 5}}$

Gradient = -3

• Parallel lines have the same gradient, therefore gradient, m is -3

${ \rm{y = mx + c}}$

• At point (0, -4)

${ \rm{ - 4 = ( - 3 \times 0) + c}} \\ \\ { \rm{c = - 4}}$

y intercept is -4

${ \boxed{ \boxed{ \mathfrak{answer : }}{ \rm{\: \: y = - 3x - 4}}}}$

Fill in the blank 8(? +3) =48+24

Triss [41]

Answer:

Step-by-step explanation:

treat the ? as an x. you need to get it by itself. but first you should distribute the 8.

8x + 24 = 48 +24

8x+24 = 72

take the 24 and subtract it from 72

8x= 48

now divide both sides by 8

x= 6
