Answer:
The answer to your question is: y = -1/2 x + 3
Step-by-step explanation:
Data
slope = m = 2
y-intercept = 3
line l is ⊥
Process
1.- Calculate the slope of line l
l = - 1/ m
l = - 1 / 2
(m)(l) = (2)(-1/2)
= -1 As m x l is "-1" the lines are perpendicular
2.- Find the line of line l
Equation y - y1 = m (x - x1)
Point (0, 3)
y - 3 = - 1/2 (x - 0) Substitution
y - 3 = -1/2 x Simplification
y = -1/2 x + 3
Answer:
C: H <u>> </u> 60
Step-by-step explanation:
H is 60 in or taller, underlined indicates that it's also 60 in, not just above it.
It would be: 2/5 /2 = 2/10
so your answer is 2/10
Answer:
7 Hours 12 Minutes
Step-by-step explanation:
So they one of the printer increases at a rate of 1/12 and the other increases at a rate of 1/18. Since you don't know the time it actually takes, you will replace both numerators with and x. (x/12 and x/18). You want to set these up so that they are adding. (x/12 + x/18=1). Since you're adding, you want to change it to the same denominator. The lowest is 36 so you multiply x/12 by 3/3 (so you don't unbalance the equation) and x/18 by 2/2. You'll end up with 3x/36 + 2x/36= 1 which will simplify to 5x/36=1. Multiply each side by 36 to leave the variable by itself. It becomes 5x=36 and when you divide it by 5 you get 7.2. So it's seven and .2 hours, which is equivalent to7 and 1/5 of an hour or 7 hours and 12 minutes.
The value of CD is 10.7 cm , Option C is the right answer.
<h3>What is a Line Segment ?</h3>
A line segment is a line of fixed measure.
From the figure , as Triangle ABC is a right angled triangle
sin 30 degree = (Perpendicular / Hypotenuse)
∠ B = 30° , AB= 10 cm
sin 30 = AC/10
AC = 5 cm.
To determine CD ,
In Triangle ADC ,
tan 25 = Perpendicular / Base
tan 25 = AC / CD
tan 25 = 5 / CD
CD = 5 / 0.4663
CD = 10.7 cm
Therefore the value of CD is 10.7 cm , Option C is the right answer.
