Answer:
r = 94
Step-by-step explanation:
Solve the equation by isolate the variable, r. Note the equal sign, what you do to one side, you do to the other. Add 26 to both sides:
r - 26 (+26) = 68 (+26)
r = 68 + 26
Add:
r = 94
r = 94 is your answer.

Answer:
1/2 + 5/2 i
Step-by-step explanation:
(-5+i) i
---------* --------
2i i
cannot have i in the denominator so we multiply by i
(-5+i) i -5i + i^2
---------* -------- = ----------------
2i i +2i^2
remember i^2 = -1
-5i + -1 -1 -5i
= ---------------- = ------------------
+2(-1) -2
get rid of the negative in the denominator by multiplying the top and bottom by -1
(-1 -5i) * -1
= ------------------
-2*(-1)
(1 +5i)
= ------------------ = 1/2 + 5/2 i

Answer: the vertex is (12,−144)
Step-by-step explanation:
Use compatible numbers to find two estimates that the quotient is between. For example:
1,624 divided by 3
<span> 1500 / 3 = 500 </span>
<span>1800 / 3 = 600</span>
<span>an</span><span> = </span>a<span>n–1</span><span> + 21 the answer is c
</span>
