Answer:
∠Y = 104°
Step-by-step explanation:
vertical angles are equal ⇒ ∠DAN = ∠SAY = 48°
Sum of interior angles of a triangle = 180°
⇒ ∠SYA + 56 + 48 = 180
⇒ ∠SYA = 76°
Angles on a straight line add up to 180°
⇒ ∠Y + ∠SYA = 180°
⇒ ∠Y + 76 = 180
⇒ ∠Y = 104°
The large rectangle in front is 351.86 square in. and the other shape is 645.88 square in. Added together, the total area is C) 997.74
Answer:
D. for the first one, A. for the second (not certain)
Step-by-step explanation:
1. 36/2 (two books every visit) = 18, multiplied by 3 because that's how many often he does to the library (every 3 weeks)
2. 13/2 = w/5 because for every 13 cups of water, there is two cups of cleaner, so for w (unknown amount of water) there would be 5 cups of concontrated cleaner.
Answer:
Statement 1 and 2
Step-by-step explanation:
If you take t^2 - 16t + 55 and find some of its graphical values, you will get:
Turning point: (8,-9)
Roots: (5,0) and (11,0)
When this graph is plotted and you imagine the x axis to be time (as stated in the question), each of the roots (x - intercept) must be when the swimmer goes under and when they come back up.
This means that the swimmer dived under the water at 5 seconds and came back up at 9, making the first 2 statements correct.
Now the fourth statement is ruled out.
The fifth statement is not plausible as the graph would have to have more than 2 roots for the swimmer to enter the water twice.
That leaves the third statement. If you imagine the depth of the swimmer to be the y axis of our imaginary graph, and we know that the y axis of the turning point is -9, that means that the swimmer's deepest dive was 9 feet under the water, ruling out the third statement too.
Hope this helps :D
Answer:
Step-by-step explanation:
This function I believe has one x intercept which is (-2/13,0)
