Answer:
Step-by-step explanation:
1.
hours 1/2 1 1.5 2 2.5 3 3.5 4
charges 3.25 6.50 9.75 13.0 16.25 19.50 22.75 26.00
2. The garage rate of parking is ;
$3.25 = 0.5 hr
?=1----------------------twice the charge for half an hour
=2*3.25=$6.50
$6.50 per hour
3.
$6.50=1 hour
$42.25=?------------------cross multiply
$(42.25*1)÷$ 6.50 = 6 hrs 30 min
Answer:
Step-by-step explanation:
Use cosine:
We have
and the angle 17°.
Substitute:
<em>convert the decimal to the fraction</em>
<em>cross multiply</em>
<em>divide both sides by 9563</em>
We want to know when we brought it back in to the room. at that time
the temperature difference is 80 - 42 = 38 so we have to solve
<span>
38=9<span>e<span>^−.3344t</span></span></span> for t
this time we get
<span><span>38 / 9</span>=<span>e^<span>−.3344t</span></span></span>
<span>t=<span><span>ln(<span>38 / 9</span>)</span><span> / −.3344</span></span></span>
<span>t=−4.3</span>
so 4.3 minutes before 2:10
Slope of f(x)
Slope of g(x)
PART A)
The slopes of f(x) and g(x) are the same.
PART B)
The equation for line f(x)
y = 4x + b
-1 = 4(0) + b
-1 = b
y = 4x - 1
The function G(x) has a bigger y-intercept. The y-intercept of g(x) is 3, while the y-intercept of f(x) is -1.
Answer: 1) 57 degrees
2) 50 degrees
3) a- 58 degrees, b- 32 degrees
Step-by-step explanation:
78, 52, and the number inbetween = 180
if u find the inbetween number it will be vertically opposite to a
