Step-by-step explanation:
(5)(-x)
= -5x
multiply both and put the minus /(-) there
Answer:
1. Cosine
2. x = 49°
3. Sine
4. y = 41°
Step-by-step explanation:
1. The trig function that will be used to solve for x is cosine.
2. Determination of angle x
x° =..?
Adjacent = 13
Hypothenus = 20
Cos x = Adjacent /Hypothenus
Cos x = 13/20
Take the inverse of Cos
x = Cos¯¹ (13/20)
x = 49°
3. The trig function that will be used to solve for y is sine.
4. Determination of angle y.
y° =..?
Opposite = 13
Hypothenus = 20
Sine y = Opposite /Hypothenus
Sine y = 13/20
Take the inverse of Sine
y = Sine¯¹ (13/20)
y = 41°
Based on the calculation below, the total price of the items before the discount is $58.32.
<h3>How do we calculate the total price of the items?</h3>
Note: The complete question is provided before answering the question as follows:
Iliana signed up for a store credit card with no annual fee to get a discount of 12.5 percent off her entire first purchase. If she saved $7.29 on her first purchase by using this credit card, what was the total price of the items before the discount?
The question is now answered as follows:
Total price of the items = Amount saved / Discount rate
Total price of the items = $7.29 / 12.5%
Total price of the items = $58.32

Answer:
5 = log₂ 32
Step-by-step explanation:
we can identify that the base = 2 and the exponent is 5
using the attached reference, we can express this in the following logarithmic form:
5 = log₂ 32
For 30 hours Julio is paid 30r dollars.
For the extra 5 hours he worked he earns 5*1.4r = 7r dollars
So the equation is
30r + 7r = 436.60
37r = 436.60
r = 436.60 / 37 = 11.80
His normal hourly rate is $11.80 answer
