Answer:
-cos(x)
Step-by-step explanation:
y¹ = cos(x)
y² = -sin(x)
y³ = -cos(x)
y⁴ = sin(x)
Every 4th derivative is sin(x)
123 = 4(30) + 3
y¹²⁰ = sin(x)
y¹²¹ = cos(x)
y¹²² = -sin(x)
y¹²³ = -cos(x)
Answer:
M+11=L
Step-by-step explanation:
- M= the weight of Marcia's dog.
- L equals the weight of Lisa's dog.
The weight of Marcia's dog plus 11 = the weight of Lisa's dog.
Answer:
3(x - 5)(x + 1).
Step-by-step explanation:
3x^2 - 12x - 15
Dividing through by 3:
= 3(x^2 - 4x - 5)
We need 2 numbers whose sum is -4 and whose product = -5. That is -5 and +1 , so the factors are:
3(x - 5)(x + 1).
The points on the red arc are points A and B
The measure of the red arc is 75 degrees
<h3>How to determine the measure of arc XYZ?</h3>
From the complete question, we have:
Angle DCE = 75 degrees
By vertical angles theorem,
Angle ACB = Angle DCE = 75 degrees
So, we have:
Angle ACB = 75 degrees
The measure of the red arc is the same as the measure of the angle ACB.
So, we have:
Red arc = 75 degrees
Hence, the measure of the red arc is 75 degrees
