(1 point) Find the equation of the line that contains the point (8,6) and is perpendicular to the line 3x + 2y = 2. Write
the equation in the form y = mx + b and identify m and b.
Answers
Step-by-step explanation:
Equation of given line:
3x+2y=2
2y=-3x+2
y=-3/2 x +2
slope =m1=-3/2
As lines are perpendicular:
m1×m2=-1
-3/2×m2=-1
required slope=m2=2/3
By using point slope form:
y-6=2/3(x-8)
3y-18=2x-16
3y=2x-16+18
3y=2x+2
y=2/3 x+2
m=2/3 ,b=2

determine is true Given a right triangle with side lengths of 4, 5, and 3, if we increase the length of the hypotenuse by 2 units but decrease the length of each leg by 1 unit, then the resulting triangle is still a right triangle.
Answers
9514 1404 393
Answer:
False
Step-by-step explanation:
The new side lengths are 3-1 = 2 and 4-1 = 3. The new longest side is 5+2 = 7.
The side lengths 2, 3, 7 do not form any sort of triangle, much less a right triangle.
The statement is false.

Qu. In a triangle ABC, side AB has length 10cm, side AC has length 5cm, and angle BAC = θ
where θ is measured in degrees. The area of triangle ABC is 15cm^2
(a) Find the two possible values of cos θ
Given that BC is the longest side of the triangle,
(b) find the exact length of BC.
Answers
Answer:
To find cosθ, use the formula for the area of a triangle i.e. AREA=1/2 x a x b x sinC.=> For this case: 15= 1/2 x 10 x 5 x sinC to find sinC.=> SinC = 3/5 thus, Arcsin(3/5)=+- 4/5 or +-0.8
To find the exact length of BC, use the cosine rule.=> c(sq)=a(sq)+b(sq)-2abCosC=> c(sq)=10(sq)+5(sq)-2(10)(5)(+-4/5)=> c(sq)= Square root of 205

The sum of the present ages of a son and his father is 60 years. Six years ago, father's
age was five times the age of the son. After 6 years, what will be son's age?
Answers
Answer:
15 years old
Step-by-step explanation:
The equation for their present ages is s+f=60. Six years ago would make it 54 and since the father's age six years ago was 5 times his son's the equation would be s+5s=54 (add the common terms) 6s=54. 54/6 is 9. So the son's age is 9, currently. In six years, the kid will be 15.
