The solution is Option C.
The section on the graph which represents the equation at which Calvin spends his time at friend's house is section S
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
On a graph, a linear equation forms a straight line. On a graph, a nonlinear equation produces an S-curve, a bell curve, or another nonlinear shape.
Let the total time spend by Calvin at school = 7 hours
Let the total time spend by Calvin at friend's house = 1 hour
Let the total time spend by Calvin at a store = 30 minutes
From the graph , we can see that
The section Q represents the line from x = 1 to x = 8 which means a total time of 7 hours is spend by Calvin at school
And , section S represents the line from x = 9 to x = 10 which means a total time of 1 hour is spend by Calvin at friend's house
And , section U represents the line from x = 10.5 to x = 11 which means a total time of 30 minutes is spend by Calvin at a store
Hence , the solution is section S of on the graph

g is a trigonometric function of the form g(x)=a sin (bx+c)+d.
The function intersects its midline at (-1 , 6) and has a minimum point at (-3.5 , 3)
Find a formula for g (x). Give an exact expression.
Answer:
Formula for g(x) is [tex]g(x) = 3 sin(\frac{\pi }{5}x + \frac{\pi }{5} ) + 6[/tex]
Step-by-step explanation:
Given - g is a trigonometric function of the form g(x)=a sin (bx+c)+d. The function intersects its midline at (-1 , 6) and has a minimum point at (-3.5 , 3)
To find - Find a formula for g (x). Give an exact expression.
Proof -
Given that,
g(x)=a sin (bx+c)+d
We know that, Midline is present in between maximum and minimum
Here given that, minimum is present is 3 and midline is present at 6
So, Maximum occurs at 9.
Now,
We know that,
Standard form of sine function is - g(x) = Asin(B(x-C)) + D
Where
A = Amplitude
and Amplitude = (Maximum - minimum) / 2
= (9 - 3)/ 2
= 6/2 = 3
⇒A = 3
Now,
Period = [tex]\frac{2\pi }{B}[/tex]
⇒B = (2π) / Period
= (2π) / 10
= π/5
⇒B = π/5
Now,
Phase Shift : C = -1 ( i.e. 1 to the left)
Vertical Shift : D = 6
So,
We get
g(x) = Asin(B(x-C)) + D
= [tex]3 sin(\frac{\pi }{5}(x -(- 1))) + 6[/tex]
⇒[tex]g(x) = 3 sin(\frac{\pi }{5}x + \frac{\pi }{5} ) + 6[/tex]
∴ we get
Formula for g(x) is [tex]g(x) = 3 sin(\frac{\pi }{5}x + \frac{\pi }{5} ) + 6[/tex]

Answer:
m∠ZWX = 105°
Step-by-step explanation:
Properties of a kite,
1). One diagonal of a kite bisects at least one pair of opposite angles.
2). Diagonals of a kite kite are perpendicular to each other.
In ΔWTZ,
m∠WZT = [tex]\frac{1}{2}(m\angle WZY)[/tex]
= [tex]\frac{1}{2}(100)[/tex]
= 50°
m∠WTZ = 90° [By second property]
m∠WZT + m∠WTZ + m∠ZWT = 180°
50° + 90° + m∠ZWT = 180°
m∠ZWT = 180° - 140°
= 40°
Similarly, in ΔWTX,
[tex]m(\angle WXT)=\frac{1}{2}(m\angle WXY)[/tex]
m(∠WXT) = [tex]\frac{1}{2}(50)[/tex]
= 25°
m(∠WTX) = 90°
m∠WTX + m∠WXT + m∠TWX = 180°
90° + 25° + m∠TWX = 180°
m∠TWX = 180° - 115°
= 65°
Since, m∠ZWX = m∠ZWT + m∠TWX
Therefore, m∠ZWX = 40° + 65°
= 105°

An advertising company charges $40 per half-page advertisement and $75 per full-page advertisement
Michael has a budget of $800 to purchase 13 advertisements.
(a) Define a variable for each unknown
Write a system of equations to represent the situation and solve the system
(b) How many half-page advertisements does Michael purchase?
Show your work.
(c) How many full-page advertisements does Michael purchase?
Answer:
F=full page H=half page
40H+75F=800
H+F=13 so H= 13-F substitute 13-F for H in the first equation.
40(13-F)+75F=800
520-40F +75F=800
35F= 280 so F=280/35=8
8 fullpage and 5 halfpage ads

Given:
The equation is:
[tex]\dfrac{y}{p-q}=\dfrac{y}{p+q}[/tex]
To find:
The value of y.
Solution:
We have,
[tex]\dfrac{y}{p-q}=\dfrac{y}{p+q}[/tex]
On cross multiplication, we get
[tex]y(p+q)=y(p-q)[/tex]
[tex]yp+yq=yp-yq[/tex]
[tex]yp+yq-yp+yq=0[/tex]
[tex]2yq=0[/tex]
Dividing both sides by 2q, we get
[tex]\dfrac{2yq}{2q}=\dfrac{0}{2q}[/tex]
[tex]y=0[/tex]
Therefore, the correct option is A.

If y varies directly as x and y = 64 when x = 16, what is the value of y when x = 12 ?
Answer: Y=48
Y is 4 times more than x. If x=12, y=48. Notice in the first part of the question, if you divide 64 by 4, you get 16. This means in order to get your answer, you must mulitiply x by 4 to get y. 12x4=48.

Solve n - 24 = 28. Be sure to show all work.
Answer:
n= 52
Step-by-step explanation:
n= 28+24
n= 52
Hello
Answer:
n=52
Step-by-step explanation:
n-24=28
n=24+28
n=52
You solve n by adding 24 to both sides to get n by itself which is n= 24+28. After you add 24 and 28 together you get 52. So n=52.

What is the solution to the following system of equations
5x + 4y = 40 6x + 4y =44
Answer:
X=4, y=5
Step-by-step explanation:
5x + 4y =40 equation 1
6x + 4y =44 equation 2
-1(5x + 4y)=-1(40) multiply equation 1 by -1 so equation will eliminate y
-5x - 4y=-40 modif equation 1
6x + 4y= 44 equation 2
x=4. Add above 2 equations
solve for y:
5x + 4y =40
5(4)+4y=40
20+4y =40
4y=20
y=5
check solution ;
6x+4y=44
6(4) + 4(5)=44
24 + 20=44
44=44
