A road is inclined at an angle of 6°. After driving 5,440 feet
Natalija [7]
<h3>Answer:  B)  569 feet</h3>

========================================================

Work Shown:

sin(angle) = opposite/hypotenuse

sin(6) = a/5440

5440*sin(6) = a

a = 5440*sin(6)

a = 568.634840176034

a = 569 feet, which shows why <u>choice B</u> is the answer.

This value is approximate. Make sure your calculator is in degree mode. One way to check is to compute sin(30) and you should get 0.5

side note: 569 feet is roughly equal to 0.1078 miles.

Question 7
prisoha [69]

To solve this problem you must apply the proccedure shown below:

1. You have the following system of equation:

\left \{ {{-4x-2y=-12} \atop {4x+8y=-24}} \right.

2. As you can see, you can cancel out the variable x, because it has equal coefficient with different signs at both equations. Then, if you add both equations, you obtain:

6y=-36\\y=-6

3. Let's substitute the value obtained into the second equation to calculate the other variable:

4x+8(-6)=-24\\4x-48=-24\\x=6

The answer is: (6,-6).

Hi Help me with question 6b) pls
Romashka-Z-Leto [24]

Answer:

k = 9

Step-by-step explanation:

Consider the pattern on the right side , that is

T_{k} = k(k + 2) + 1 = k² + 2k + 1

Equating

k² + 2k + 1 = 100 ( subtract 100 from both sides )

k² + 2k - 99 = 0 ← in standard form

(k + 11)(k - 9) = 0 ← in factored form

Equate each factor to zero and solve for k

k + 11 = 0 ⇒ k = - 11

k - 9 = 0 ⇒ k = 9

But k > 0 , then k = 9
