Using linear function concepts, the correct option is given by:
The slope is −0.3. Starting at 3.6, the GPA will decrease by 0.3 for every text sent in class.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.For this problem, the function is:
y = 3.6 - 0.3x.
The function has a initial GPA of 3.6(student who sends 0 texts), then for each text the student sends, the GPA falls by 0.3(slope of -0.3), hence the correct option is:
The slope is −0.3. Starting at 3.6, the GPA will decrease by 0.3 for every text sent in class.

Find the circumference
and the area of a circle with radius 9 m.
Use the value 3.14 for and do not round your answers. Be sure to include the correct units in your answers.
Answer:
56.52m is the circumference. The area is 254.34[tex]m^{2}[/tex]
Step-by-step explanation:
The equation for the circumference of a circle is c=2πr with r being the radius. So 2(3.14)(9)=56.52m. The area equation for a circle is A=π[tex]r^{2}[/tex] so it would be (3.14)(9)^2 or (3.14)(81) which equals 254.34[tex]m^{2}[/tex]

Which exponential function bests models the graph below?
A.
B.
C.
D.
D.
Option A. [tex]Y = 3(2)^{X}[/tex]
Here, looking at the graph we can see that when x = 0, the value of y will be 3. Thus, (0, 3) is a solution to the given function.
Putting x = 0 in the given options, we see that
A. y = 3(1) = 3 (as anything raised to the power is 1)
B. y = 2(1) = 2
C. y = 4(1) = 4
D. y = 3(1) = 3
Thus, we can eliminate option B and C as (0, 3) does not satisfy these equations.
Now, if we take x = 1, from the graph we can see that the value of y will be 6.
Substituting x = 1 in the remaining two options, we get
A. y = 3(2) = 6
D. y = 3(4) = 12
Thus, D is also eliminated.
Option A, y = 3(2)^x is the correct answer.

find y
Please help, I’m not sure what I’m doing.
Step-by-step explanation:
Fact 1: Alternate angles are equal.
Angles, (5x-11)° and (3x+17)° are ALTERNATE angles and so,
(5x-11)° = (3x+17)°
5x - 3x = 17 + 11
2x = 28
x = 28 ÷ 2
x = 14
NB: x does NOT have the degree sign because it's NOT an angle on its own, but rather within the bracket/part of the calculation to get the angle degree.
Fact 2: Opposite angles are equal.
Y° and (3x+17)° are OPPOSITE angles
y = (3x+17)°
y = (3x14) + 17
y= 42 + 17
y = 59°

Two hundred liters of a punch that contains 35% fruit juice is mixed with300 liters of another punch. the resulting fruit punch is 20% fruit juice. find the percent of fruit juice in the 300liters of punch
If two hundred liters of a punch that contains 35% fruit juice is mixed with 300 liters of another punch and the resulting fruit punch is 20% fruit juice, then the percent of fruit juice in 300 liters of punch is calculated to be 10%.
The percentage of fruit juice in 300 liters of punch can be calculated by forming a linear equation.
A linear equation also termed a first-degree equation is an equation with one or more variables that have the highest power of one.
A linear equation for this problem can be given as:
the volume of the first punch × percentage of fruit juice in the first punch + the volume of the second punch × percentage of fruit juice in the second punch = total volume × total percentage of fruit juice
Consider x = percentage of unknown fruit juice
Now add the given values in the equation:
200 × 35 + 300(x) = 500 × 20
7000 + 300(x) = 10000
300(x) = 10000 - 7000
300(x) = 3000
x = 3000 / 300
x = 10%
Hence, the percentage of fruit juice in 300 liters of punch is calculated to be 10%.

Amount of one tin of paint is $14 and the total amount Mr. Chong have is $172.
Let amount of one tin of paint = x
Let the total amount Mr. Chong having = y
On buying 18 tins of paint, he will need another $80. This can we mathematically represented as,
18x = y + 80
On rearranging this equation can be written as,
18x - y = 80 equation 1
On buying 10 tins of paint, he will will have $32 left. This can we mathematically represented as,
10x = y - 32
On rearranging this equation can be written as,
-10x + y = 32 equation 2
On adding equation 1 and equation 2, we get
18x - y -10x + y = 80 + 32
8x = 112
x = (112/8) = 14
On substituting x = 14 in equation 2 , we get
-140 + y = 32
y = 172
So, amount of one tin of paint is $14 and the total amount Mr. Chong have is $172.

Equation: 2x + x + 72 = 180m∠1 = 72°m∠2 = 108°Step-by-step explanation:
The angles lie on a straight line summing to total 180 degrees.
Form an equation:
m∠1 + m∠2 = 180
2x + x + 72 = 180
and solve:
3x + 72 = 180
3x = 180 - 72
3x = 108
x = 36
Find m∠1: 2(x) = 2(36) = 72°Find m∠2: x + 72 = 36 + 72 = 108°Answer:
see below
Step-by-step explanation:
We are here given a straight line which is splitted into two parts by a line , such that it makes two angles.
Also we know that the angle measure of a straight line is 180° . Therefore; here the sum of angles 1 and 2 will be 180° .
So that,
==> angle 1 + angle 2 = 180°
==> 2x + x + 72° = 180°
==> 3x = 180° - 72°
==> 3x = 108°
==> x = 108°/3
==> x = 36° .
The equation which we used to solve the problem is ,
==> Equation = 2x + x + 72° = 180°
For finding the individual angels substitute the value of x into their expressions , as ;
==> angle 1 = 2x = 2(36°) = 72°
==> angle 3 = x + 72° = 36° + 72° = 108° .

If a quadratic function has the rule f(x)=(x-h)^2+k, what will cause a vertical translation?
Option 1: Changing the value of h
Option 2: Changing the value of k
Please help me as soon as possible, thanks.
to apply a vertical translation we changed the value of k, which is the y-value of the vertex of the quadratic equation.
Then the correct option is the second one.
What will cause a vertical translation?
First, remember that for a general function f(x) we define a vertical translation of N units as:
g(x) = f(x) + N
If N > 0, the translation is upwards.If N < 0, the translation is downwards.In this case, we have the function:
f(x) = (x - h)^2 + k
If we apply a vertical translation of N units, then we get the new function:
f'(x) = (x - h)^2 + k + N
Now we have two constants, we can define:
k ' = k + N
Then the new quadratic function is:
f'(x) = (x - h)^2 + k'
So, as you can see, to apply a vertical translation we changed the value of k, which is the y-value of the vertex of the quadratic equation.
Then the correct option is the second one.

The table shows the distance traveled by 4 cycleists. Sort the speeds of the riders, in miles per hour, from slowest to fastest.
The speed from slowest to the fastest is Julio; Elana; Kevin; Lorena.
Given that a table shows the distance traveled by 4 cyclists as shown in attached images.
Speed is defined as . The rate at which an object changes position in any direction. Speed is measured as the ratio between distance and time traveled.
Firstly, we will calculate the speed of Elena.
The given distance is 20(1/2) mi or it can be written as 41/2mi and the time is 2(1/4) hr or 9/4hr.
Now, substitute the values in speed formula that is
Speed=Distance/Time
Speed=(41/2)/(9/4)
Speed=(41/2)×(4/9)
Speed=82/9 mi/hr.
Now, we will calculate its speed of Julio.
The given distance is 12(1/4) mi or it can be written as 49/4mi and the time is 1(1/2) hr or 3/2hr.
Now, substitute the values in speed formula that is
Speed=Distance/Time
Speed=(49/4)/(3/2)
Speed=(49/4)×(2/3)
Speed=49/6 mi/hr.
Further, we will calculate the speed of Kevin.
The given distance is 20(2/3) mi or it can be written as 62/3mi and the time is 1(2/3) hr or 5/3hr.
Now, substitute the values in speed formula that is
Speed=Distance/Time
Speed=(62/3)/(5/3)
Speed=(62/3)×(3/5)
Speed=62/5 mi/hr.
Furthermore, we will calculate the speed of Lorena.
The given distance is 33(1/4) mi or it can be written as 133/4mi and the time is 2(1/3) hr or 7/3hr.
Now, substitute the values in speed formula that is
Speed=Distance/Time
Speed=(133/4)/(7/3)
Speed=(133/4)×(3/7)
Speed=57/4 mi/hr.
Hence, the speeds from slowest to fastest from the given table is Julio; Elana; Kevin; Lorena.

Write an equation for each situation, in terms of t,t, and determine which high school is projected to have more students in 11 years.
Answer:

Then and .
After 6 years the number of students in both high schools would be the same.
Step-by-step explanation:
For High School A, let denote the number of students after years. Define analogously.
Since we start out at 850 students at High School A and it is growing by 35 students every year, we must have that .
Since we start out at 700 students at High School B and it is growing by 60 students every year, we must have that .
Setting the two equations equal to each other, we see that
