Answer:

-9

Step-by-step explanation:

Use the order of operations. Do these operations in this order:

Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction

Note: when either multiplication and division, or addition and subtraction are there, go left to right.

Equation: -1 - 2 · {(-1) + 5}

Solve:

-1 - 2 · {(-1) + 5}
-1 - 2 · {4}
-1 - 8
-9

*Challenge*

Using the same method, see if you can solve this equation:

In ΔABC, the lengths of a, b, and c are 22.5 centimeters, 18 centimeters, and 13.6 centimeters, respectively.

Given the values of the three sides of the triangle, we can apply the Cosine Law to find the angles of the triangle. Recall that for we can express the value of c through the equation below.

$c^{2} = a^{2} + b^{2} - 2abcosC$

Rearranging this equation, we can find the value ∠C as shown below.

$\cos C = \frac{a^{2}+b^{2}-c^{2}}{2ab}$
$C = cos^{-1} (\frac{a^{2}+b^{2}-c^{2}}{2ab})$

We can apply the same reasoning for finding the value of ∠B as shown.

$B = cos^{-1} (\frac{a^{2}+c^{2}-b^{2}}{2ac})$

Plugging in the values of the sides (see image attached) from the given. It will now be straightforward to compute for ∠B and ∠C.

$C = cos^{-1} (\frac{22.5^{2}+18^{2}-13.6^{2}}{2(22.5)(18)})$
$C \approx 37.19$

$B = cos^{-1} (\frac{22.5^{2}+13.6^{2}-18^{2}}{2(22.5)(13.6)})$
$B \approx 53.13$

Answer: ∠C = 37.19° and ∠B = 53.13°

What is the momentum of 200kg portable if it travels 50 meters in 5seconds

kvasek [131]

Momentum = mass * velocity

50 meters in 5 seconds = 50/5 = 10 m / second

Required momentum = 200*10 = 2,000

I cant remember how to write the units for this.

12. The answer is B because the sum of any two sides of a triangle must be greater than the other side.
A. 4 → 4 + 4 is not GREATER than 8
B. 8 → 4 + 8 is greater than 8 and 8 + 8 is greater than 4
C. 12 → 4 + 8 is not GREATER than 12
D. 16 → 4 + 8 is not GREATER than 16

13. The central angle containing the green beans is 360° - (195°+98°) = 67°.
If the diameter of the circle is 12 then the circumference = πd = 12π.
$\frac{67}{360}$ × 12π≈7.013
So the correct answer is A
67/360 represents the portion of the circle which is green beans and you multiply it by the circumference to find the length of that arc.
