The answer is C. I got this by doing a^2 + b^2= c^2. 50^2 + 16^2=c^2, 2500 + 256 = c^2, 2756 = c^2, then you take the square root of 2756 and that gives you your answer 52.50 yards. Hope this helps :D

I AM BEGGING YALL, PLEASE HELP ME OUT

sweet-ann [11.9K]

Answer:

(2a,2b)

(-4a,b)

Step-by-step explanation:

for the first one

the x value of coordinate L is going to be twice the value of the x coordinate of k (a)

That being said the x value of L = 2a

The y value of L is going to be half the value of the y value of coordinate A ( 4b )

4b/2=2b so the y value of coordinate L is 2b

now we put the values as an ordered pair

The answer would be (2a,2b)

The Length of one side of a parallelogram is 3 more than twice the length of the adjacent side. The perimeter of the parallelogr

katovenus [111]

Answer: 4 cm and 11 cm.

Step-by-step explanation:

1. You can calculate the perimeter of a parallelogram as following:

$P=a+b+c+d$

Where a+b+c+d are the lenghts of the sides.

By definition the parallelogram has two pairs of parallel sides, therefore:

a=c and b=d

Then, you can calculate the perimeter as following:

$P=2(a+b)$

2. Let's call the adjacent side $x$ , then the other side is 2x+3.

3. Substitute values and solve for x:

$30=2(x+2x+3)\\30=2(3x+3)\\30=6x+6\\24=6x\\x=4$

4. Then the lenghts of the sides are:

$x=4cm\\2x+3=2(4cm)+3=11cm$

Answer: (assuming the first three terms are -6, -2, 2)

(a) f(n) = 4n - 10

(b) 30

Step-by-step explanation:

(So, just as a preface, I made this answer assuming the first three terms are -6, -2, and 2 since I couldn't find a provided fourth term as the problem said)

(a) In order to create an equation for an arithmetic sequence, you need to find the common difference(d) and the 0th term. You can find the common difference by finding the difference between two consecutive terms:

2 - (-2) = 4 (or (-2) - (-6) = 4), so d = 4

Now, you need to find the 0th term. To do this, you can just subtract the d from the first term, -6:

-6 - 4 = -10.

At this point, you can write the equation:

f(n) = -10 + 4n (this is the 0th term plus the common difference, 4, times the nth term)

f(n) = 4n - 10 (reorganize by value of exponents)

(b) In order to find the 10th term, you just need to plug it into the previous equation:

where n = 10, and f(n) = 4n - 10,

f(n) = 4(10) - 10 (substitute n into the equation)

f(n) = 40 - 10 (multiply the term in the parenthesis by the constant)

f(n) = 30 (subtract)
