Answer:
307.5$
Step-by-step explanation:
150$. 105% of it added.
Since 105% is 1.05, multiply the percentage by the cost to get the money added.
150*1.05=157.5
Then ADD it to the price/savings.
150+157.5=307.5$
Answer:
A) (2x+15)=65=180°
Step-by-step explanation:
Hey there!
It's a straight line, which means that the sum will be 180°.
So, (2x+15)=65=180°

Hope this helps!
-16t^2+400=0
16t^2=400
take square root on both sides.

4t=20
t=20/4
t=5
D because 1.29 plus 2.75 is 4.04(the money that he used to make the case) and subtract that with $12 and you get $7.96 as the profit.
Answer:
A: f(x)=10cos(2π/5 x)+10
Step-by-step explanation:
The coefficient of x in the cosine argument of the function will be 2π/period. Since the period is 5, the coefficient is 2π/5. This observation eliminates choices B and C.
The description "not a reflection of the parent function over the x-axis" means the multiplier of the cosine function is not negative, eliminating choice D.
The remaining choice A matches the description.
