What is the solution to the inequality -2.1x + 2.9 > 15.5?
Answers
Answer:
x<−6
Step-by-step explanation:
Let's solve your inequality step-by-step.
−2.1x+2.9>15.5
Step 1: Subtract 2.9 from both sides.
−2.1x+2.9−2.9>15.5−2.9
−2.1x>12.6
Step 2: Divide both sides by -2.1.
−2.1x−2.1>12.6−2.1
x<−6

necessary, round your answer to the nearest
hundredth.
A 0.28
© 0.5
B 0.18
D 0.09
Answers
Answer:
0.18
Step-by-step explanation:
9/50 is the same as 18/100, we know this because if we multiply both 9 and 50 by 2, it gives us 18/100. 18/100 can be turned into the decimal, 0.18, so your answer is 0.18

Which expression is equivalent
to cos(4x)?
Answers
Answer: A 2(2cos^2(x) - 1)^2 - 1
Step-by-step explanation: E 2020
The expression equivalent to cos(4x) is 2cos²(2x) - 1.
Out of the options provided, the correct choice is 2cos²(2x) - 1.
The expression equivalent to cos(4x) can be found using trigonometric identities and formulas. One such identity is the double angle identity for cosine:
cos(2θ) = 2cos²(θ) - 1.
We can apply this identity to the expression cos(4x) by considering it as cos(2(2x)).
Using the double angle identity, we have:
cos(4x) = cos(2(2x)) = 2cos²(2x) - 1.
Therefore, the expression equivalent to cos(4x) is 2cos²(2x) - 1.
Out of the options provided, the correct choice is:
O 2cos²(2x) - 1.
By substituting 2x for θ in the double angle identity, we obtain the equivalent expression for cos(4x).

Answers
Answer:
Part A: 15.55
Part B: 0.45
Step-by-step explanation:
Part A:
The giraffe is already 14.29 so when you add the length of its tongue (equation 14.29 + 1.26) then that would equal 15.55
Part B:
The giraffe is trying to eat some leaves that are 16 feet above the ground so you would subtract 16 - 15.55 to see how much farther it needs to reach, so the answer is 0.45.
(This is what I got, I apologize if I get this wrong. If I messed up on something, someone please correct me, thank you and have a nice day!)
Answer:
Part A: It can reach 15.55 feet.
Part B: Need to reach 0.45 feet farther to get to the leaves of a 16 feet tree.
Step-by-step explanation:
giraffe + tongue = reach
14.29 + 1.26 = 15.55
tree height - giraffe reach = extra distance
16 - 15.55 = 0.45 feet

Answers
===============================================
Explanation:
Subtract the second equation from the first one
[tex]\ \ \ \ 3x+3y-5z = 4 \ \ ... \text{ eq 1}\\-(4x-4y+z = -1) \ \ ... \text{ eq 2}\\---------\\\ \ -x+7y-6z = 5[/tex]
Let's call that result equation 4.
Now focus on equation 3 and equation 4
equation 3 is -x+7y-6z = 2
equation 4 is -x+7y-6z = 5
Note how the left hand sides are identical, but the right hand sides are different. This means that we have an inconsistent system with no solutions. No matter what numbers we pick for x,y,z, there is no way to make all three given original equations to be true.
