Using the Pythagorean identity, sin^2C + cos^2C = 1, solve for sinC.
Answer:
[tex]\sin(C)=\pm\sqrt{1-\cos^2(C)}[/tex]
Step-by-step explanation:
Given the Pythagorean Identity:
[tex]\sin^2(C)+\cos^2(C)=1\\[/tex]
We want to solve for sin(C).
First, we will subtract cos²(C) from both sides:
[tex]\sin^2(C)=1-\cos^2(C)[/tex]
Next, we will take the square root of both sides. Since we are taking an even-root, we will need to add plus/minus. Hence:
[tex]\sin(C)=\pm\sqrt{1-\cos^2(C)}[/tex]
Y=x+1, xy+2x=0
Help please
Answer:
x = 0,-3
y = 1,-2
Step-by-step explanation:
We can substitute x+1 for x in the second equation
x(x+1) + 2x = 0
x^2 + 3x = 0
x(x+3) = 0
x = 0,-3
y = 1,-2

the line has a rise of 20 and a run of -4 and goes through the points (-2,25) (0,15) (3,0) and (5,10) write the equation in slope-intercept form
Answer:
y = -5x + 15
Step-by-step explanation:
the y intercept was given (0,15)
to find the slope do rise/run
20 / -4 = -5
so the slope is -5
4.5÷6=
estimate the quotient
Answer:
0.75 - 0.8
Step-by-step explanation:
4.5/6 = 0.75
The closest number to round 0.75 to is 0.8
We are given the expression:
4.5 / 6
Simplifying the given expression:
We can rewrite 4.5 as 4/10:
[tex]\frac{45}{10}*\frac{1}{6}[/tex]
Since 45 and 6 have a common factor: 3
[tex]\frac{3*15}{10}*\frac{1}{3*2}[/tex]
The 3 in the numerator and the denominator will cancel out:
[tex]\frac{15}{10}* \frac{1}{2}[/tex]
We know that 15/2 is 7.5
[tex]\frac{7.5}{10}[/tex]
0.75
Hence, the quotient of the expression: 4.5/6 is 0.75

Q.The rectangular front windshield of the bus has the length of 1.5√3 m and the width of 1.5 m . The wipers are attached to the bottom corners. If the length of each wiper is equal to the width of the windshield, find the percentage of the windshield that wipers can reach.
(Solve this task without using Trigonometry)
Answer:
Area covered by wiper=area of arc(A0D)+area of traingleAOB+area of arc(BOC)
We know AO and OB are wipers,whose lengths are 1.5
In ∆ABC
AB^2+BC^2=AC^2
(1.5√3)^2+(1.5)^2=(AC)^2
2.25×3+2.25=(AC)^2
2.25×4=AC^2
AC=3
Also AO=1.5
similarly using Pythagoras theorem in ∆OBC
we get
OC=1.5
this shows that point O is the bisector of diagonal AC
so,AO=OC
also from property of rectangle we know that, diagonal bisects each other equally
so,O will also be the bisector of diagonal BD
hence OB=OD=1.5
AC=BD (property of triangle)
AC/2=BD/2
OB=OC,hence OB=OC=OD=OA=1.5=AD=BC
Hence OAD will be an equilateral triangle
so
angle OAD=60
similarly angleOBC=60
area of sector=angle of that sector ×area of circle/360
area of arc(AOD)+arc(BOC)=60/360 ×3.14 ×1.5×1.5 +60/360 ×3.14×1.5×1.5
=2×(60/360)×1.5×1.5
area of triangleAOB=area of rectangle/4 (diagonal divides the rectangle in 4 equal parts)
area of triangle=1.5×1.5√3/4
=>1.5×2.6/4=3.90/4
=0.975 or 0.98(approx)
Area covered by wiper=.98+2×60/360 ×3.14×1.5×1.5
=.98+0.75×3.14=2.35+0.97
=2.35+.98
Percentage of area of windshield covered by wiper=3.3×100/3.9=84.61
hence percentage of area of windshield covered by wiper is 85percent(approx)

You go to a bakery and see that two cookies
and a glass of milk cost $3.75. One cookie with a
glass of milk cost $2.45. How much will a glass of
milk cost alone? Start by writing a system of
equations, then solve the system.
Answer:
$1.15
Step-by-step explanation:
You take 3.75 - 2.45 = 1.3 because the 2.45 is taking off the price of one cookie and than when you minus them you get the price of how much the cookie alone costed. then take 2.45 - 1.3 to get how much the milk costs.
For an acute angle θ, the equation sin(θ)=cos(6) is true. What is the value of θ? Show or explain your answer
Answer:
[tex]\theta= 84[/tex]
Step-by-step explanation:
Given
[tex]\sin(\theta) = \cos(6)[/tex]
Required
Find [tex]\theta[/tex]
In trigonometry,
If [tex]\sin(\theta) = \cos(\alpha)[/tex], then
[tex]\theta + \alpha = 90[/tex]
So, in this case:
[tex]\theta + 6= 90[/tex]
Subtract 6 from both sides
[tex]\theta + 6-6= 90-6[/tex]
[tex]\theta= 90-6[/tex]
[tex]\theta= 84[/tex]
Hence, the value of [tex]\theta[/tex] is 84 degrees
