Please help!!!!! it's a word problem and I don't understand how to do it at all

andre [41]

7We can see that line NM = JK so NM also equals 10.
We know NL = 23 and NM = 10 therefore, ML = NL -NM ML = 23 -13
ML = 10
The last thing to solve is the length of KL
KL = ML / sine 34
KL = 10 / 0.55919
KL = 17.9

Total fence length required = JK + KL + NL =
13 + 17.9 + 23
= 53.9 yards
Cost of Fencing = $3.50 * 53.9 =
 $188.65

Which number is prime? 36 37 35 38

dybincka [34]

A number is prime if its only divisors are 1 and the number itself.

Out of your numbers, 36 and 38 are even, and thus divisible by 2, so they aren't prime.

Similarly, 35 ends with 5, so it's divisible by 5, and is not prime.

37 is divisible only by 1 and 37, and thus it's prime.

notsponge [240]

Answer:

Step-by-step explanation:

1. Subtract the 4x on both sides = -14 = -2x

2. Divide -2 on both sides to get -14/-2 = x

3. -14/-2 = 7 so 7 = x

What would the equation be for d=0.68t + 1.5

frozen [14]

Answer:

Step-by-step explanation:

d=0.68t + 1.5 if t time is 3 hrs

d=0.68(3) + 1.5

= 2.04 + 1.5

d= 3.54 ft

d=0.68t + 1.5 if d depth is 4 ft solve for t

d - 1.5 = 0.68t

(d - 1.5) / 0.68 = t

(4 - 1.5) / 0.68 = t

t = 2.5/0.68

t = 3.68 ft

Find the roots of the polynomial equation.

True [87]

Answer:

3 ± i5

Step-by-step explanation:

Here we're given four sets of possible roots of the given polynomial. Each set consists of two complex quantities and 1 real quantity.

First, we determine whether +4 is a root, then whether -4 is a root. Let's use synthetic division to do that:

-----------------------

4 / 1 -2 10 136

4 8 72

---------------------------

1 2 18 208 Since the remainder is not zero, 4 is not a root.

Eliminate the first two possible answer choices, and assume that -4 is a root.

Let's check this out to be certain:

-----------------------

-4 / 1 -2 10 136

-4 24 -136

---------------------------

1 -6 34 0

Since the rem. is zero, -4 is a root, and the coefficients of the 2nd-degree quotient are 1, -6 and 34.

In other words, a = 1, b = -6 and c = 34.

Let's apply the quadratic rule to find the roots:

6 ± √(36 - 4[1][34] ) 6 ± √ (-100)

x = ------------------------------ = ----------------------- = 3 ± i5

2 2

So the correct answer is the last one of the four given possible answers:

3 ± i5
