Mathematics
1 answer:
olga_2 [115]3 years ago

Answer:

Step-by-step explanation:

The area of a triangle is

A=\frac{1}{2}bh and we have the base (12m) and we need to find the height. Using Pythagorean's Theorem:

6^2=4^2+h^2\\36=16+h^2\\20=h^2\\h=2\sqrt{5}

That's the height that we will sub into the area formula:

A=\frac{1}{2}(12)(2\sqrt{5})\\A=12\sqrt{5}\\A=26.8

How to rearrange this equation to get v by itself
s344n2d4d5 [400]
V^2/(1-v^2/c^2)=R
v^2=R(1-v^2/c^2)
v^2=R-Rv^2/c^2
v^2-Rv^2/c^2=R
v^2(1-R/c^2)=R
v=sqrt(R/(1-R/c^2))
where R was original right side, dont forget plus minus

What is the solution to the system of equations y = -x - 5 and y = 2x + 4
Delvig [45]

Answer:

(-3,-2)

Step-by-step explanation:

y = -x - 5

y = 2x + 4

plug in one of the y equations

(2x+4)= -x - 5

2x+4=-x-5

3x=-9

x= -3

plug in x to one of the y equations

y= -(-3) -5

y=3-5

y= -2

x= -3, y= -2
