There are 5 slides, i've provided image for them all i need help with it. if your going to answer write it in order from slide 1-5 so it's easier to understand.
Answer:
mark as brainleast and fo-ll-ow me
Slide 1.
Part A.
1. Band A: y = 600
2. Band B: y = 1.25x + 350
Part B.
200 students.
Slide 2.
Part A.
Fixed cost = $150
Rate per student served = $6
Part B.
To figure the cost/person, look at the change in cost divided by the change in attendance.
For 100 students, cost = $750.
For 150 students, cost = $1050.
Change in cost = $300
Change in students = 50
Cost per additional student = 300/50 = $6
Assuming the costs are linear, then the price charged for 100 students reflects the cost per student + a 'fixed cost' that applies to the order as a whole.
100 * 6 = $600, so the fixed cost is 750-600 = 150.
We can check this notion by substituting in the other equation.
Does 150*6 + 150 = 1050? Yes.
150*6=900
900+150 = 1050.
Slide 3.
Part A.
She can choose either band, with $9.75 per ticket, if 200 students attend
Part B.
Check the cost using band A and 200 people, including food
600 + 150 + (6*200) =
600 + 150 + 1200 = $1950
Cost per ticket: = 1950/200 = $9.75
Cost using band B, 200 people, including food:
350 + 1.25(200) + 150 + (6*200) =
350 + 250 + 150 + 1200 = $1950
Cost per ticket: 1950/200 = $9.75
This means that Paula can choose either band, and the ticket cost will be the same.
Slide 4.
Part A.
Cost per ticket: $8.50 (of Band A, since it is the cheaper one)
Part B.
Check the cost using band A and 300 people, including food
600 + 150 + (6*300) =
600 + 150 + 1800 = $2250
Cost per ticket: = 2250/300 = $8.50
Cost using band B, 200 people, including food:
350 + 1.25(300) + 150 + (6*300) =
350 + 375 + 150 + 1800 = $2675
Cost per ticket: 2675/300 ≈$8.92
Which means that in this scenario is Band A is less expensive.

Answer:
C.
Step-by-step explanation:
Hi there!
We know that [tex]x^0[/tex] is equal to 1 because any number raised to the zero is always going to be 1.
With that out of the way, we are left with [tex]x^-^3/1[/tex], which is equivalent to [tex]x^-^3[/tex]
Using negative exponent rules,
The expression is flipped and the -3 becomes a positive 3.
It will look like this
[tex]\frac{1}{x^3}[/tex]
Your answer is C.

solve the equation below. please include the steps.
x^2+8x+15=0
Answer:
[tex]x_{1} =-5\\and \\x_{2} =-3[/tex]
Step-by-step explanation:
Solve by using factoring ------->
rewrite the expresion
x^2+8x+15=0
x^2+5x+3x+15=0
factor out x from the expression
x^2+5x+3x+15=0
xx(x+5)+3x+15=0
xx(x+5)+3(x+5)=0
factor out x+5 from expression
(x+5)x(x+3)=0
when the product of factors equals 0, at least one factor is 0
x+5=0
x+3=0
solve the equation for x
x = -5
x = -3
the equation has 2 solutions
[tex]x_{1} =-5, x_{2} =-3[/tex]
Step-by-step Explanation:Quadratic formula
[tex]x=\frac{-8+\sqrt{8^{2} -4x1x15} }{2x1}[/tex]

multiply the numbers
[tex]x=\frac{-8+\sqrt{64-60} }{2}[/tex]
subtract the numbers

Solve forx: 10 (2x - 4) + 5 = 2r - 8 1 ОА. x =- 19 10 O B. x= =- 1 С O c. x = 1 O D. x = =
Answer:
Option D
Step-by-step explanation:
Given expression is,
10(2x - 4) + 5 = 2x - 8
By using distributive rule,
20x - 40 + 5 = 2x - 8
20x - 35 = 2x - 8
Now we subtract 2x from both the sides of the equation
20x - 35 - 2x = 2x - 8 - 2x
18x - 35 = -8
By adding 35 on both the sides of the equation
18x - 35 + 35 = - 8 + 35
18x = 27
By diving with 18 from both the sides of the equation
[tex]\frac{18x}{18}=\frac{27}{18}[/tex]
x = [tex]\frac{3}{2}[/tex]
Therefore, Option D will be the correct option.

Atiya rolls a 7.0 kg bowling ball down the
alley for the championship. One pin is still
standing, and Atiya hits it head-on with a
velocity of 9.0 m/s. The 2.0 kg pin moved
forward with a velocity of 14.0 m/s. What is
the new velocity of the bowling ball?
Answer:
5 m/s
Step-by-step explanation:
According to law of conservation of momentum :
m1u1 + m2u2 = m1v1 + m2v1
m1 = 7kg ; u1 = 9m/s ; m2 = 2kg ; u2 = 0 ; v2 = 14 m/s
m = masses ; u = initial velocities ; v = final velocities
m1u1 + m2u2 = m1v1 + m2v1
7*9 + 2*0 = 7*v + 2*14
63 + 0 = 7v1 + 28
63 = 7v1 + 28
63 - 28 = 7v1
35 = 7v1
v1 = 35 / 7
v1 = 5 m/s

Gertrude started an experiment with 15 gummy bears. After 6 days, there were 1,523 gummy bears. Write an exponential function that could be used to model the number of gummy bears after x days if the number of gummy bears changes at the same rate. Round to the 4th decimal place (ten thousandth)
y=a*b^x
a=
b=
9514 1404 393
Answer:
y = 15·2.1599^x
Step-by-step explanation:
We know that the number changed by the ratio 1523/15 = 101.5333... in 6 days, so the daily multiplier is the 6th root of this:
b = 101.5333...^(1/6) = 2.1599 . . . rounded to 4 dp
Of course, the coefficient 'a' in the equation is the initial number, 15.
Your exponential equation is ...
y = 15·2.1599^x
a = 15
b = 2.1599
A limnologist takes samples from a creek on several days
and counts the numbers of flatworms in each sample,
The limnologist wants to look at the relationship between
the temperature of the creek and the number of
flatworms in the sample. The data show a linear pattern
with the summary statistics shown below:
mean
standard
deviation
= 10.2
Sx = 2.8
x = creek temperature
(C)
j = 37.6
$y = 30.8
y = number of
flatworms
• = -0.98
Find the equation of the least-squares regression line
for predicting the number of flatworms from the
creek temperature.
Round your entries to the nearest hundredth.
Answer:
y = 147.56 - 10.78x
Step-by-step explanation:
Given :
x = 10.2 ; y = 37.6 ; Sx = 2.8 ; Sy = 30.8 ; r = - 0.98
The regression equation :
y = mx + c
Where ;
m = slope ; c = intercept
Slope = r * (Sy/Sx)
Slope = - 0.98 * (30.8 / 2.8)
Slope = - 0.98 * 11 = - 10.78
To obtain c :
y = mx + c
y - mx = c
37.6 - (-10.78)(10.2) = c
37.6 + 109.956 = c
147.556 = c
Hence, equation becomes :
y = 147.556 - 10.78x
y = 147.56 - 10.78x
Answer:
y = 147.56 + -10.78x
