To begin with, we can simplify y using the Pythagorean identity:
y = 2 cos²(x) + 3 sin²(x) + 5
y = 2 (cos²(x) + sin²(x)) + sin²(x) + 5
y = 2 + sin²(x) + 5
y = sin²(x) + 7
Next, we can further rewrite this using the half angle identity for sine:
y = (1 - cos(2x))/2 + 7
y = 15/2 - 1/2 cos(2x)
Now, since cos(x) is bounded between -1 and 1, we have
max(y) = 15/2 - 1/2×(-1) = 15/2 + 1/2 = 8
and
min(y) = 15/2 - 1/2×1 = 15/2 - 1/2 = 7
Then the sum of the maximum and minimum is 8 + 7 = 15.

Rewrite as a simplified fraction.
3.541
41 is repeating
If x = 3.5414141…, then 10x = 35.414141… and 1000x = 3541.414141…. Then
1000x - 10x = 3541.414141… - 35.414141…
990x = 3506
x = 3506/990 = 1753/495

Answer:
7/12
Explanation:
Here are the steps to follow:
Write down the factors for the numerator and the denominator.
Determine the largest factor that is common between the two.
Divide the numerator and denominator by the greatest common factor.
Write down the reduced fraction.
Answer:
7/12
Step-by-step explanation:
[tex] \frac{1}{3} + \frac{1}{2} = \frac{2 + 3}{6} = \frac{5}{6} - \frac{1}{4} = \frac{20 - 6}{24} = \frac{7}{12} [/tex]
Alex had $29 in a bank account. He withdrew $13 for pizza and then $18 for a movie. How much money does Alex have left in his account?
Answer:
-12
Step-by-step explanation:
18 plus 13 is 41 29 subtracted from 41 is -12
Answer:
- $2
Step-by-step explanation:
Alex withdrew money twice, or he subtracted those amounts from the total that he had.
In this case, he withdrew $13 first, and then $18, or:
13 + 18 = 31
$31 dollars in all.
Alex had $29. Subtract the total that he withdrew from the amount he had:
29 - 31 = -2
Alex has - $2, or he owes the bank $2 with interest.

4. In the diagram, ABCD is a straight line. Calculate the values of x and y.
Answer:
x is 108° and y is 144°
Step-by-step explanation:
for x:
[tex] x + 36 \degree + 36 \degree = 180 \degree \\ \{isoceles \: triangle \: angle \: sum \} \\ x + 72 \degree = 180 \degree \\ x = 180 \degree - 72 \degree \\ x = 108 \degree[/tex]
for y:
[tex]y + 36 \degree = 180 \degree \\ \{straight \: line \: angles \} \\ y = 180\degree - 36\degree \\ y = 144\degree[/tex]
Answer:
X+36+36=180
X+72=180
X=180-72
X=108
36+BC^D=180
BC^D=180-36
BC^D=144
BC^D corresponds with y
Therefore y=144
HELP ASAP will give BRAINLIEST
Hey there! I'm happy to help!
The question tells us that m∠JKL is 54. We see from the diagram that this is the combination of the angles m∠JKM and m∠MKL. So, we can combine their values, which are equal to 54 to find x.
13x+1+5x+4=54
We combine like terms
18x+5=54
We subtract 5 from both sides.
18x=49
We divide both sides by 18.
x=2.7222222....
Now, we want to find the measure of m∠MKL. We plug our x value into the value of this angle and evaluate.
5(2.722....)+4=17.61111....... or 17 11/18.

Explain how confounding might be an issue with this study
Answer:
perhaps because math is a subject that builds on itself. so if you miss or dont know one key formula then it is difficult to understand the others.
math is also a subject that has many different ways to solve one thing
I need help mhm yeah need help I can’t stop cussing ( not so much tho ) so my mum got mad at me and she keeps comparing me to my cousin and saying that she’s way better than me *sigh* it just gives me no self-esteem and brings me down, makes me thinking that I’m not worth it and everything else i don’t know what to do anymore any advice? ( sorry if this is not educati)
Answer:
just a random Teenage who's been through the same thing
Step-by-step explanation:
if you really care about what your mom think I'd suggest changing some thing's about you . maybe study more or something . if you don't usually try then go ahead try harder.
but if youre doing everything right but your cousin just seem to be better then you can't do much but try to explain to her that you're trying your best
stay safe and don't do anything you'd regret
Your question is not educational, but I'll be happy to give you some advice.
From a person who has dealt with a parent comparing me to others, I completely understand how you feel. Parents do sometimes get mad at their children for misbehaving but it not acceptable whatsoever to bring them down like that. I hope you understand that no one but YOU is allowed to dictate your worth. If you can, I suggest bringing this matter up with your mother and tell her how her remarks make you feel. If you cannot do that, I suggest speaking with a school counselor, friend, relative, or teacher about this. Sometimes expressing your feelings with others is the best medicine.
Have a great day!
Choose the postulate that is NOT represented in the diagram.
A
If two lines intersect, they intersect in exactly one point.
B
Given a point on a plane, there is one and only one line perpendicular to the plane through that point.
