Answer:
A) Total distance around the park is 14.6 miles
B) The total distance drove by racer 730 miles
Step-by-step explanation:
Given as :
The length of park = 4.6 miles
The width of park = 2.7 miles
Let the total distance cover around park = Perimeter of park = P miles
So, Perimeter of rectangular park = 2 × Length + 2 × width
or, P = 2 × 4.6 + 2 × 2.7
I.e P = 9.2 + 5.4
Or, perimeter = 14.6 miles
A ) ∴ Total distance around the park = 14.6 miles
B ) The total distance drove by racer = 50 times around the park
So, The total distance drove by car = 50 × Total distance around the park
∴The total distance drove by car = 50 × 14.6 = 730 miles
Hence A) Total distance around the park is 14.6 miles
B) The total distance drove by racer 730 miles answer
Answer:
Step-by-step explanation:
Given that events A1, A2 and A3 form a partiton of the sample space S with probabilities P(A1) = 0.3, P(A2) = 0.5, P(A3) = 0.2.
i.e. A1, A2, and A3 are mutually exclusive and exhaustive
E is an event such that
P(E|A1) = 0.1, P(E|A2) = 0.6, P(E|A3) = 0.8,
(6,1)&(5,4)
(7,-3)&(4,-8)
(-8,0)&(1,5)
Basically, you are to find the line that passes through 2 points.
Equation: y2-y1=m(x2-x1)
• x1: 6, x2: 5, y1: 1, y2: 4
(4-1)/(5-6)=m
m=3/-1
m=-3
Hence, m= -3x10^0
• x1: 7, x2: 4, y1: -3, y2: -8
(-8--3)/(4-7)=m
m=(-8+3)/-3
m=-5/-3
m=5/3
m=1.66666667
Hence, m=1.6667x10^0
• x1: -8, x2: 1, y1: 0, y2: 5
(5-0)/(1--8)=m
m=5/(1+8)
m=5/9
m=0.55555556
Hence, m=5.56x10^-1
Hope this helps!
Arranged in descending order means the terms are arranged in the order of the exponent, from the largest to the smallest. the exponent is the little number up right to y,
3y^4+6y^3+2Y^2-5y
so the third term is 2y^2
His new hourly pay will be 13.6475
13.25 + 3% = 13.25 + 0.3975 = 13.6475
