Area of rectangle with diagonal of 5 in but length not given

1 answer:

3 0

Draw a rectangle with diagonal 5 in. Inside this rect. are 2 acute triangles of hypotenuse 5. Note that 3^2 + 4^2 = 5^2; thus the width of the rect. is 3 and the length is 4, with the result that the hypo. is sqrt(3^2+4^2), as expected.

Answer:

-157.87

Step-by-step explanation:

1) the rules are:

$log_a(bc)=log_ab+log_ac;$

and

$log_ab^c=c*log_ab.$

2) according to the rules above:

$log_7(yz^8)=log_7y+8log_7z=-6.19-8*18.96=-157.87.$

Answer:

$-6x+2y=\frac{3}{2}$

Step-by-step explanation:

The equation Thomas wrote is:

$y=3x+\frac{3}{4}$ ...equation 1

Let us subtract 3x from both sides to get:

$-3x+y=\frac{3}{4}$

We now multiply through by 2 to get:

$-6x+2y=\frac{3}{2}$ ....equation 2

We can see that equation one and two are equivalent and hence have the same solution.

Therefore Sandra's equation is $-6x+2y=\frac{3}{2}$

Write an equation of the line that passes through (−1,3) and is parallel to the line y=2x+2

Komok [63]

Start off by writing the equation y = mx - b. Then plug in what you do know

3 = 2(-1) - b (m is the slope and parallel lines have the same slope). Then solve

3 = -2 - b

5 = b

So y = 2x + 5
