<span>The answer would be: an = 10( one half )n − 1; average rate of change is </span><span>negative fifteen halves.
</span><span>This question is about exponent function/series. You are given 3 points from the function, point A (1,10), point B( 2, 5) and point C(4,1.25).
If you insert point A to the function, </span><span>an = 10( one half )^n − 1 </span>will give a result of 10 for n=1.
For n=0, the result would be:
an = 10( one half )^n − 1
an= 10(1/2)^0-1
an= 10(1/2)^-1= 10* 2= 20
Then the average rate of change from n=0 to n=2 would be:
Rate of change= (y2-y1)/ (x2-x1)
Rate of change= (5-20)/ (2-0)= -15/2= <span>negative fifteen halves</span>
Answer:1875cm^3
Step-by-step explanation:
Volume = mass/density
15,000/8=1875
#1
= 9
Let's solve your equation step-by-step.
8.88=4.44(x−7)
Step 1: Simplify both sides of the equation.
8.88=4.44(x−7)
8.88=(4.44)(x)+(4.44)(−7)(Distribute)
8.88=4.44x+−31.08
8.88=4.44x−31.08
Step 2: Flip the equation.
4.44x−31.08=8.88
Step 3: Add 31.08 to both sides.
4.44x−31.08+31.08=8.88+31.08
4.44x=39.96
Step 4: Divide both sides by 4.44.
#2
= y = -3
Step 1: Simplify both sides of the equation.
Step 2: Subtract 2 from both sides.
Step 3: Divide both sides by 5.
Answer:
x=7
Step-by-step explanation:
Solve.
7x-5x-3=x+4
Calculate like terms.
7x-5x=2x
Rearrange.
2x-3=x+4
Apply inverse addition.
2x-3+3=x+4+3
2x=x+7
Isolate 2x by subtraction.
2x-x=x-x+7
x=7
