Answer:
x= -2
Step-by-step explanation:
Step 1. In order to find the zeros of the function, we must factor it.
Step 2. To factor this, we have to find two numbers that multiply to 4 and add to 4 which is 2 ( 2*2=4 and 2+2=4)
step 3. 0=(x+2)(x+2)
Step 4 make (x+2) equal to zero and solve which gives us -2, so -2 =x.
Through the metric system
Answer:
x = 5
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 12² = 13², so
x² + 144 = 169 ( subtract 144 from both sides )
x² = 25 ( take the square root of both sides )
x = = 5

The answer is 1/9 and 1/2
Answer:
Arc length MK = 15.45 units (nearest hundredth)
Arc measure = 58.24°
Step-by-step explanation:
Calculate the measure of the angle KLN (as this equals m∠KLM which is the measure of arc MK)
ΔKNL is a right triangle, so we can use the cos trig ratio to find ∠KLM:
where:
- is the angle
- A is the side adjacent the angle
- H is the hypotenuse (the side opposite the right angle)
Given:
- = ∠KLM
- A = LN = 8
- H = KL = 15.2
Therefore, the measure of arc MK = 58.24° (nearest hundredth)
Given:
- r = 15.2
- ∠KLM = 58.24313614°
