You can obtain the graph of the function y=-2sinx-1 from the graph of the function y=sinx making such transformations:
1. <span>the multiplication by -2 increases y value twice and then symmetrically reflects the graph y=2sinx about the x-axis;</span>
2. adding -1 to the <span>y=-2sinx you translate the graph 1 unit down.
</span><span>
</span><span>On the added picture black line is a graph of y=sinx and red line is a graph of y=-2sinx-1.</span>
Check:
1. When x=0, y=-2sin0-1=-1;
2. When

, then

.
Answer:
Step-by-step explanation:
Substituting y = 4x+1 into 2y = -x-1 gives the equation
2(4x+1) = -x-1
Solve the equation:
8x+2 = -x-1
9x = -3
x = -⅓
Answer: Probability = 0.2
Step-by-step explanation:
Given data:
Mean production time = 32.20 seconds
Standard deviation = 1,05seconds
probability that a full production run will take less than 32 seconds on average to produce
= P(Xbar<32)
= P(Z<-0.8518)
= 0.2
