that would be the letter d :)
each value of x has a unique value of y
Answer:
= 4sqrt3
Step-by-step explanation:
-2i sqrt -12
= -2i * i sqrt12 <-- i^2 = -1
= -2i^2sqrt12
= -2(-1)sqrt12
= 2sqrt12
= 2 * 2 sqrt3
= 4sqrt3
Answer:
171
Step-by-step explanation:
First you plug -4 into the g(x) equation
g(-4)= 1-3(-4)
Use pemdas
g(-4)= 1+12
g(-4)= 13
Next you plug 13 into the f(x) equation
f(13)= 13^2 + 2
First you do 13^2=169
Add 2 and you get 171
Answer: A
<u>Step-by-step explanation:</u>
≅ 
⇒ ∠XOY ≅ ∠ZOY
≅ 
since they are both a radius
≅ based on reflexive property
∴ ΔXOY ≅ ΔZOY by SAS
So, 
≅ 
by CPCTC
ZY = 10.2 is given
so, XY = 10.2 by substitution property
Answer:
20%
Step-by-step explanation:
<u><em>Given/To Find:</em></u>
<em>A $52.50 screen door is on</em>
<em>sale for $42. Find the percent</em>
<em>of discount on the door.</em>
<u><em>Solve:</em></u>
<em>Formula: Value 1 - Value 2 ÷ Original Value × 100</em>
<em />
<em>Hence we have:</em>
<em>52.50 - 42 = 10.5</em>
<em>10.5 ÷ 52.50 = 0.20</em>
<em>0.20 × 100</em>
<em>=20%</em>
<em />
<em>Check Answer:</em>
<em>52.50 × 20% = 10.5</em>
<em>52.50 - 10.5 = 42</em>
<em>Hence, the percent of discount on the door is 20%</em>
