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
P / 9 = 72
Multiply both sidess by 9
P / 9 (9) = 72 (9)
p = 648
Answer:
They are related becasue if you find the area of a parallelogram then divide it by two then you have the area of a triangle
Step-by-step explanation:
<u>Explanation</u><u>:</u>
Consider ABCD is a rhombus
We know that
All sides are equal in rhombus i.e,
⇛AB=BC=CD=DA
and AC and BD are digonals
Given that
Diagonal and the side of the rhombus are equal.
⇛AB = BC = CD = DA = AC
Diagonal AC divides the rhombus into two triangles .
They are ∆ BAC and ∆ DAC
In triangle BAC
BA=BC=AC,(Given)
⇛∠ BAC=∠ABC= ∠ACB =60°→→→Eqn(i)
Similarly in ∆DAC ,
DA=DC=AC
⇛∠DAC=∠ACD=∠ADC=60°→→→Eqn(ii)
From eqn(i) and eqn(ii)
∠A=∠BAC+∠DAC=60°+60°=120°
and
∠B= ∠ABC = 60°.
and
∠C=∠ACB+∠ACD=60°+60°=120°
and
∠D =∠ADC=60°
∴ ∠A = 120° , ∠B = 60° ,∠C = 120° & ∠D = 60°
<u>Answer:</u><u>-</u>The measures of the all angles in the rhombus are 120° , 60° ,120° and 60°.
