Answer:
x² - y² and x^4 - 36
Step-by-step explanation:
(x + y)(x - y)
(x² + 6)(x² - 6)
Answer: first blank is 4/25.
second blank on the top row is 16:100=4:25.
First blank on the second row is 13/50.
The second blank on the second row is 26:100=13:50.
The first blank on the third row is 33:50.
The first blank on the fourth row is 4/7.
The second blank on the fourth row is 57%.
The third blank is 0.57.
Step-by-step explanation:
16/100 simplified is 4/25. 16÷4=4 100÷4=25
ratios are also fractions.
26/100 simplified is 13/50. 26÷2=13 100÷2=50
66/100 simplfied is 33/50. 66÷2=33 100÷2=50
4÷7(rounded down)=0.57
B.addition property of multiplication
D.inverse property of multiplication
E.commutative property of addition
(A) Find the value of x. Round to the nearest tenth of a degree<span>
Given that the distance of the ground is 9ft.
Length of the plank is 41 ft
In order to get the angle formed between the ground and the foot of the plank,
cos (theta) = ground / plank
cos (theta) = 9 / 41
</span><span>cos (theta) = 0.21951...
</span>theta = cos^-1(<span>0.21951...)
</span><span>theta = 77.3 degrees
</span><span>(b) Find the height above the ground where the plank touches the wall. Round to the nearest tenth of a foot.
</span><span>
Height = square root (plank^2 - ground^2)
Height = square root (41^2 - 8^2)
</span><span>Height = square root (1600)
</span><span>Height = 40
(A) 77.1 Degrees
(B) 40 feet</span>
