Answer:
a(
+
) = = -13
Step-by-step explanation:
Given that a = -1, b=2 and c= -3
find the value of a(
+
)
Just substitute the values given for each variable
a(
+
) = (-1)(
+
) ; do the exponents first
a(
+
) = (-1)(4+9)=(-1)(13) ; now add inside the parenthesis;
a(
+
) = -13 ; and multiply by -1

Answer:
(c) 52.0
Step-by-step explanation:
The angle whose cosine is 8/13 is found using the inverse cosine function:
y° = arccos(8/13) ≈ 52.0°
y ≈ 52.0
__
The calculator button to compute this value is probably labeled cos⁻¹. You may need to access the function using a <em>Shift</em> or <em>2nd</em> key. The calculator must be set to degrees mode to prevent the answer from appearing in radians or grads. If you use a spreadsheet, your formula may look like ...
=DEGREES(ARCCOS(8/13))
Part A: The coefficients (numbers) are 75 and 25, while the variables (letters) are x and y.
Part B: There are two terms, meaning that this expression is a <em>binomial</em>. The two terms are <em>75x</em> & <em>25y</em>
Part C: The term in the expression that shows the total earned from pizzeria is 75x, which, when simplified, will give you the pizzeria term.
