y = A(Bx - C)ⁿ + D
A is a vertical stretch (or shrink if |A| < 1
B is a horizontal shrink by factor of (or stretch if |B| < 1)
C is a shift to the right (or left if C is negative)
D is a shift up (or down if D is negative)
*************************************************
y = x² - 5 ⇒ D = -5
Answer: shift down 5 units
Answer:
$1.50 is 105 Naira
Step-by-step explanation:
If the exchange rate is 1:70, that means that in order to get the amount of Naira equal to some amount of US dollars, you would multiply the number of US dollars by 70. And so we get...
1.5 x 70 = 105 (Naira)
Answer:
Standard deviation = 11.30 m/h
Mean = 57.74 m/h
Step-by-step explanation:
Assume that the travel speed is normally distributed.
The corresponding z-score to the 5th and 90th percentile of normal distribution are, respectively, -1.645 and 1.282.
For any given speed X, the z-score is:
If z = -1.645 for X = 39.15 and z= 1.282 for X=72.23, the following system can be solved for the mean and standard deviation of vehicle speed:
The standard deviation is 11.30 m/h and the mean is 57.74 m/h.
I can't see pictures, but I'm going to solve the inequality and hope it helps.
2x+3>-9
-3 -3
2x>-12
/2 /2
x>-6
To graph this, you need to convert this to slope form.
x>-6/1
-6 is the rise, and 1 is the run. That means that when you start at the origin, (0,0), you go down 6 units, because of the negative, and go right 1 unit. Repeat until you have maybe about 3 points, or until you can make a line. Then because the inequality has >, you shade to the right.
