It's A.
All you need to do is plug in the X from the ordered pair, then solve.
y=-5x-4
y=-5(10)-4
y=-50-4
y=-54
Which is NOT -52, so the answer is indeed A
Answer:
3.5 to 20.5 hours
Step-by-step explanation:
The range of the sine function is -1 to 1, so the range of H will be ...
-8.5 +12 = 3.5
to
8.5 +12 = 20.5
The length of the day varies by 17 hours from 3.5 hours to 20.5 hours.
It's annuity problem
To solve your question use the formula of the present value of annuity ordinary which is
Pv=pmt [(1-(1+r)^(-n))÷r]
Pv present value?
PMT yearly payments 18000
R interest rate 0.09
N time 20 years
So
Pv=18,000×((1−(1+0.09)^(−20))÷(0.09))
pv=164,313.82
Answer:
14 units
Step-by-step explanation:
Area=b×h, where b is the unknown base and h=10
140=b×10, b=14 units
Answer:
C {(-4, 2), (-2, 1), (2, 0), (4, 5)}
Step-by-step explanation:
The domain is the set of x-values for which the function is defined.
<h3>Choices</h3>
A) The relation is <em>only defined for x=2</em>. It is not a function, because x=2 maps to an infinite number of y-values.
B) The domain is an infinite number of x-values. The listed values are included in the domain, but they are <em>not the entire domain</em>.
C) The list of first-values in the ordered pairs is the domain of the function it matches the given domain.
D) The list of first-values in the ordered pairs is <em>not the same as the given domain</em>.
