Answer:
A and B
Step-by-step explanation:
Nadeen started with 18 tokens and will lose 3 with every game he/she/they play.
The equation that would represent this is a) 18 - 3x. b, when distributed, is also 18 - 3x.
3(6 - x) ---> multuply 3 with 6 and 3 with x
18 - 3x
Answer: C
Hello,
Step-by-step explanation:
WZ=7-3=4
YW²=XW*WZ=3*4=12 ==> WY=2√3
In the right triangle YWZ, using the Pythagorean's theorem:
YZ²=WY²+WZ²=12+4²=28
YZ=2√7≅5.29150....
Answer C
Question: Assume the complete question as, Two forces of 20 Newton’s and 30 Newton’s² act on a point. The resultant force is 40 Newton’s. Find the angle between the two forces
Answer:
75.5°
Step-by-step explanation:
From the question,
Using cosine rule,
R² = P²+Q²-2PQcosθ................... Equation 1
Where θ angle between the the two forces.
Given; R = 40 Newton, P = 20 Newton, Q = 30 Newton.
Substitute these values into 1
40² = 20²+30²-[2×20×30(cosθ)]
1600 = 400+900-(1200cosθ)
1600 = 1300-1200cosθ
1200cosθ = 1600-1300
1200cosθ = 300
cosθ = 300/1200
cosθ = 0.25
θ = cos⁻¹(0.25)
θ = 75.5°
Hence the angle between the forces is 75.5°
Hello!
The range of a function is all the y values it spans.
In this case, we are presented an equation y = -|x|. We can figure out the range from this information. For now, let's look at the parts individually.
The | | indicates absolute value. Absolute value is the distance a number is from 0. For example, the absolute value of -3, or |-3|, would be 3, as -3 is 3 away from 0. From only absolute value, the range would be y is greater than or equal to 0, as all numbers are a positive number away from 0.
Now, add the negative symbol. This means that the always positive result of the absolute value would become always negative. This, therefore, gives us our final solution - y is less than or equal to 0.
Therefore, your answer is the second choice, or y ≤ 0.
Hope this helps!
