I don’t get this problem at all-
Answer:
2nd option
Step-by-step explanation:
If AB is a tangent to the circle then ∠ B is right angle
Using the converse of Pythagoras' identity.
If the square of the longest side is equal to the sum of the squares on the other 2 sides, then the triangle is right
longest side = 52 and 52² = 2704
48² + (10 + 10)² = 48² + 20² = 2304 + 400 = 2704
Then AB is a tangent to the circle since ∠ B is a right angle

At 7am there was 4 inches of snow on the ground. After that, the snow fell at a rate of 1.5 inches per hour. Equation:
Answer:
y(t) = 4 + 1.5t
.
Step-by-step explanation:
Initial amount of snow = 4 inches
Fall rate of snow = 1.5 inch per hour
Equation to model the scenario goes thus :
Initial amount of snow + (fall rate of snow * number of hours)
Let the number of hours = h
4 inches + (1.5 inch per hour * h)
Equation, y(t) becomes ;
y(t) = 4 + 1.5t
i need step by step answers
Convert the equation to Standard Form.
y=2(x+1)^(2) −4
Answer:
(-8x2-16x-8)
Step-by-step explanation:
y= (2x + 2)^2 (2 - 4)
y= (2x + 2)(2x + 2)(2 - 4)
y= −82−16−8
A biologist is studying a group of alligators in a swamp and tagged 4 hatchlings, 5 juveniles, and 6 adults. The biologist estimates that this tagged sample is a reliable reflection of the ratios of hatchlings, juveniles, and adults in the general alligator population for the area. The biologist estimates that the total number of alligators in the area is 120. The most likely number of adults in the total population is ______?
A. 32
B. 48
C. 72
D. 120
AND PLZ NO LINKSSSS
Answer:
48
Step-by-step explanation: Take the 6 adults and divide it by one of the multiple choice answers to get a ratio. The ratio of 48 / 6 = 8. You can then see if that ratio helps you add up all the alligators to 120.
4 x 8 + 5 x 8 + 6 x 8 = 120
