Answer:
PQ ≈ 9.4 cm
Step-by-step explanation:
Calculate the distance d using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = P(- 4, - 2) and (x₂, y₂ ) = Q(4, 3)
PQ =
=
=
=
≈ 9.4 cm ( to 1 dec. place )
Answer:
D
Step-by-step explanation:
Using process of elimination B and C are out because B is addition and C starts from 7. Then after reading A the equation for that would be 5g - g = 4g. That leaves D.
Answer:
30
Step-by-step explanation:
180 degrees = Triangle
Angle 1 = 60
angle 2 = 90 because it's a right triangle
Angle 3 = 180 - (60+90) = 30
60 + 90 = 150
180 - 150 = 30
Replace X with 0 and solve the equation, then replace x with 8 and solve the equation again.
Then find the difference between the 2 answers and divide that by the difference in the 2 X values.:
f(0) = 2(0) + 33(0) -3 = -3
f(8) = 2(8) +33(8) - 3 = 16 + 264 - 3 = 280-3 = 277
Difference: 277 - (-3) = 277+3 = 280
Difference between the X values 8 - 0 = 8
Average rate of change: 280 / 8 = 35
Answer: $713.7
Step-by-step explanation:
First, multiply the original price by the percentage ( In this case, 549 x .30)
Now your sum is $164.7 Add that to the original price and you get your answer.
