Given expression
[tex]\\ \rm\Rrightarrow T(t)=29-5cos\left(\cfrac{2\pi (t-12)}{365}\right)[/tex]
Now
We know according to property of cosine function
It has range of [-1,1] for all intervals .This property is enough for our calculations
Let's check
As t represents no of days hence it can't be negative
t must be a whole number set memberSo
for positive interval
We shall use the cosine interval [0,π]We know that
cosπ is -1cos0=1Hence it's enough for our range [-1,1]
Now
In the expression
29 is the vertical shiftLet
[tex]\sf cos\left(\cfrac{2\pi(t-12)}{365}\right)=n[/tex]
Substitute n for lowest and highest value of range
When n=-1
[tex]\\ \rm\Rrightarrow T(\pi)=29-5(-1)=29+5=34°C[/tex]
When n=1
[tex]\\ \rm\Rrightarrow T(0)=29-5(1)=29-5=24°C[/tex]
Highest average daily high=34°Clowest average daily high=24°CAnswer:
Highest temperature: 34°C
Lowest temperature: 24°C
Explanation:
In a Normal Trigonometry Function: y = A + B sin(x) or y = A + B cos(x)
Maximum value: A + |B|
Minimum value: A - |B|
In this trigonometric function, A = 29, B = -5
Hence find minimum/maximum:
Maximum value: A + |B| = 29 + |-5| = 34
Minimum value: A - |B| = 29 - |-5| = 24
Hence, the maximum/highest temperature is 34°C and minimum/lowest temperature is 24°C in Karachi, Pakistan.

1) -15+4r=-9
2)5-y/3=-1
3)42=5x-8
That's all, you don't have to show work, but I'd appreciate it:) asap pls
Equation #1:
-15+4r=-9We move all terms to the left:
-15+4r-(-9)=0
We add all the numbers together, and all the variables
4r-6=0
We move all terms containing r to the left, all other terms to the right
4r=6
r=6/4
r=1+1/2
Equation #2:
5-y/3=-1We move all terms to the left:
5-y/3-(-1)=0
We add all the numbers together, and all the variables
-y/3+6=0
We multiply all the terms by the denominator
-y+6*3=0
We add all the numbers together, and all the variables
-1y+18=0
We move all terms containing y to the left, all other terms to the right
-y=-18
y=-18/-1
y=+18
Equation #3:
Simplifying
42 = 5x + -8
Reorder the terms:
42 = -8 + 5x
Solving
42 = -8 + 5x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-5x' to each side of the equation.
42 + -5x = -8 + 5x + -5x
Combine like terms: 5x + -5x = 0
42 + -5x = -8 + 0
42 + -5x = -8
Add '-42' to each side of the equation.
42 + -42 + -5x = -8 + -42
Combine like terms: 42 + -42 = 0
0 + -5x = -8 + -42
-5x = -8 + -42
Combine like terms: -8 + -42 = -50
-5x = -50
Divide each side by '-5'.
x = 10

x = 10

is 9x=63,x=7 true or false
Answer:
True
9 * 7 = 63
Therefore when x=7 9x=63
The equation given is true since 7 is the solution.
What is an Equation?An equation is the statement of two expressions located on two sides connected with an equal to sign.
The two sides of an equation is usually called as left hand side and right hand side.
The given equation is 9x = 63.
There is only one variable here, x.
We have to solve this equation and find whether the solution is 7 or not.
Solution of the equation is the value of x.
9x = 63
Divide both sides of the equation by 9, then, we get,
9x / 9 = 63 / 9
9 gets cancelled in the left hand side and 63/9 = 7.
So we get,
x = 7
So the given statement is true that for 9x = 63, the solution is x = 7.
Hence the given equation is true.

One forth of one third of two fifths of a number is 15. What is the number?
A fourth of a third of two fifths is a thirtieth.
(1 x 1 x 2) / (4 x 3 x 5) = 2 / 60 = 1 / 30
A thirtieth of a number () is fifteen, the number is four hundred and fifty.
= 15 / (1 / 30) = 15 x 30 = 450
forty percent of four hundred and fifty is one hundred and eighty.
(450 / 100) x 40 = 180
Answer:
The number is 450
Step-by-step explanation:
One fourth is 1/4,
One third is 1/3
and two fifths is 2/5
let the number be x.
So,
One fourth of one third of two fifths of x is 15.
that is,
1/4 * 1/3 * 2/5 * x = 15
2/4*3*5* x = 15
2/60 * x = 15
1/30 * x = 15
1 * x = 15*30
x = 450
Therefore the number is 450

Sarah’s company sells bracelets and rings. Her first customer buys 3 bracelets and 10 rings, spending a total of $48. Her second customer buys 7 bracelets and 4 rings, spending a total of $54. How much does Sarah charge for one bracelet?
Please select the best answer from the choices provided
A. $3.00
B. $6.00
C. $12.00
D. not enough information
Sarah charges $6.00 for one bracelet.
We know that a collection of one or more linear equations containing the same variables is known as a system of linear equations in mathematics.
Let Sarah charges $x and $y for one bracelet and one ring respectively.
Since her first customer spends $48 on 3 bracelets and 10 rings, we can write it as
3x + 10y = 48 ...(1)
Since her second customer spends $54 on 7 bracelets and 4 rings, we can write it as
7x + 4y = 54 ...(2)
Now, we have to solve this system of linear equations.
Multiplying (1) by 2, 6x + 20y = 96 ...(3)
Multiplying (2) by 5, 35x + 20y = 270 ...(4)
Subtracting (3) from (4), 35x + 20y - 6x - 20y = 270 - 96
i.e. 29x = 174
i.e. x = 174/29 = 6
Therefore we can conclude that Sarah charges $6 for one bracelet. Option B is correct.

Answer:

Step-by-step explanation:

2x+10=26
2x + 10 - 10 = 26 - 10 [Subtract 10 from both sides]
2x = 1
2x/2 = 16/2 [Divide both sides by 2]
x = 8
