Answer:
The change is increasing with a percentage of change of 64%
Step-by-step explanation:
Since we have the present grater than the original, then the change is increasing
Secondly, we want to calculate the percent of change
Mathematically , that will be ;
(present - original)/original * 100%
= (90-55)/55 * 100%
= 35/55 * 100% = 63.63 which is approximately 64%

Answer:
3° and 87°
Step-by-step explanation:
<em>here's</em><em> your</em><em> </em><em>solution</em>
<em> </em><em>=</em><em>></em><em> </em> we know that measure of complementary angle is 90°
=>. one angle is. = x
=> other angle is .= (19x + 30)
=> so, x + 19x + 30° = 90°
=> 20x + 30° = 90°
=> 20x = 60°
=> x = 60/20
=> x = 3°
hence one angle is 3° and other is 87°
hope it helps
F(x)= 4x this is because everything is times 4
The explicit formula for arithmetic sequence is:
an=a+(n-1)d
where:
a=first term
d=common difference
given:
a3=22
a(17)=-20
substituting this in our equation we get:
22=a+(3-1)d
22=a+2d
a=22-2d........i
also:
-20=a+(17-1)d
-20=a+16d.....ii
but substituting i in ii we get:
-20=22-2d+16d
-20-22=14d
-42=14d
d=-3
but:
a=22-2d
a=22-2(-3)
a=28
thus the formula will be:
an=28-3(n-1)
thus the first term will be 28
the 2nd term will be:
a2=28-3(2-1)
a2=25
the 3rd term will be:
a3=28-3(3-1)
a3=28-6
a3=22
a4=28-3(4-1)
a4=28-9
a4=15
a5=28-3(5-1)
a5=28-3(4)
a5=28-12
a5=15
