The value of b is -16 and the value of ac is 60 after comparing with the standard equation.
What is a quadratic equation?Any equation of the form [tex]\rm ax^2+bx+c=0[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
As we know, the formula for the roots of the quadratic equation is given by:
[tex]\rm x = \dfrac{-b \pm\sqrt{b^2-4ac}}{2a}[/tex]
We have a quadratic function:
= 3x² - 16x + 20
On comparing with standard function:
b = -16
a = 3
c = 20
ac = 3(20) = 60
Thus, the value of b is -16 and the value of ac is 60 after comparing with the standard equation.

What is a Geometric progression?A geometric progression is a sequence in which successive terms differ by a common ratio.
It is a sequence in which the ratio of two consecutive terms is a constant.
Analysis:
first term, a= 1
second term, ar = 2
third term, ar^2= 4
common ratio = ar/a = 2/1 = 2
Sum of the G.P where n = 15
sum of G.p = a([tex]\frac{r^{n} - 1}{r-1}[/tex])
= 1([tex]2^{15}[/tex] - 1)/2 - 1 = 32768 - 1 = 32768 inches
converting the inches to yard, where 1 yard = 36 inches
so 32768/36 = 910 yards
In conclusion, the house would slide 910 yards in 15 days.

What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
We have:
A home appliance store has recently seen an increase in TV sales.
The store manager decides to raise the TV price by 25% in order to increase the store's profits.
Original price of TV = $140
Price after increasing:
= 140 + 25% of 140
= $175
The number of TV bought post-raise for $4,200 = 4200/175

The product of two consecutive positive integers is 194 more than the next integer. What is the largest of the three integers?
Answer:
16
Step-by-step explanation:
let x be a positive integer
mathematically, the statement: “The product of two consecutive positive integers is 194 more than the next integer” means x(x + 1) - 194 = x + 2
………………………………
Solving the equation x(x + 1) - 194 = x + 2 for x :
x(x + 1) - 194 = x + 2
⇔ x² + x - 194 = x + 2
⇔ x² - 194 = 2
⇔ x² = 196
⇔ x = 14 or x = -14
Since -14 < 0 then the solution to our equation is x = 14
Therefore
The largest integer of the three is x + 2 = 14 + 2 = 16
Verification:
14 × 15 − 194 = 210 − 194 = 16
Using a significance level of 5%, the appropriate conclusion for a test with a p-value of 0.0421 would be:
A significance level of 5% (more commonly referred to as 95%) corresponds to a statement that (only) a probability of 5% or less is that a particular randomly generated observation is accepted as significant.
In this example, the p-level (the true probability that the observations are randomly generated) is less than 5% (0.0421 <0.05), so we can draw the conclusion that the observations are significant.
p = 0.0421 means that the probability is only 0421/1000. The choice of significance level to reject the null hypothesis is optional. Traditionally, 5%, 1%, and 0.1% levels have been used. In rare situations, a 10% significance level is also used.

The length of one side of a triangle is 2 feet less than three times the length of its second side. The length of the third side is 3/4
of the sum of the lengths of the first two sides. Find the lengths of all three sides if the perimeter of the triangle is 17.5 feet.
P=17.5 feet
Using a system of equations, it is found that the lengths of the sides of the triangle are given as follows:
0.91 feet, 0.73 feet, 1.23 feet.
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are the lengths, given by x, y and z.
The length of one side of a triangle is 2 feet less than three times the length of its second side, hence:
y = 3x - 2.
The length of the third side is 3/4 of the sum of the lengths of the first two sides, hence:
[tex]z = \frac{3(x + y)}{4} = \frac{3(4x - 2)}{4}[/tex]
The perimeter of the triangle is 17.5 feet, hence:
[tex]x + y + z = 17.5[/tex]
[tex]x + 3x - 2 + \frac{3(4x - 2)}{4} = 17.5[/tex]
[tex]4x + \frac{3(4x - 2)}{4} = 19.5[/tex]
[tex]16x + 12x = 25.5[/tex]
x = 25.5/28
x = 0.91.
Then the other sides are:
y = 3x - 2 = 3(0.91) - 2 = 0.73 feet.[tex]z = \frac{3(4 x 0.91 - 2)}{4} = 1.23 feet[/tex]More can be learned about a system of equations at https://brainly.com/question/24342899

A car rental company offers two plans for renting a car. Plan A: $30 per day and $0.18 per mile Plan B: $50 per day with free unlimited mileage How many miles would you need to drive for plan B to save you money?
Answer:
For plan B to save money car rental need to drive 111.1 miles as [tex]\frac{x}{y}[/tex] expresses the average amounts of miles per day car rental drive and its obtained value is 111.1.
Step-by-step explanation:
In the question it is given that a car rental company offers two plans for renting a car.
Plan A: $30 per day and [tex]$\$ 0 \cdot 18$[/tex] per mile.
Plan B: $50 per day with free unlimited mileage
It is required to find that how many miles would be needed to drive for plan B to save money. be needed to drive for plan B to save money.
Step 1 of 5
In Plan A $30 per day and [tex]$\$ 0 \cdot 18$[/tex] per mile are costed so the cost of Plan A is given by following equation,
[tex]$$A=30 y+0 \cdot 18 x$$[/tex]
In Plan B $50 per day with free unlimited mileage are costed so the cost of Plan B is given by following equation,
[tex]$$B=50 y$$[/tex]
Step 2 of 5
Now comparing the obtained equations [tex]$A=30 y+0 \cdot 18 x$[/tex]
and B=50y.
[tex]$$30 y+0 \cdot 18 x=50 y$$[/tex]
Step 3 of 5
Subtract 30y from both the sides of the obtained equation 30 y+0.18x=50y and simplify using subtraction properties.
[tex]$$30 y+0 \cdot 18 x-30 y=50 y-30 y$$\\ $0 \cdot 18 x=20 y$[/tex]
Step 4 of 5
Divide both the sides of the obtained equation [tex]$0 \cdot 18 x=20 y$[/tex] by [tex]$0 \cdot 18$[/tex] and simplify using division properties.
[tex]$$\begin{aligned}&\frac{0 \cdot 18 x}{0 \cdot 18}=\frac{20 y}{0.18} \\&x=\frac{1000 y}{9}\end{aligned}$$[/tex]

Cassandra already has $224 in a bank account.
She decides to save more by depositing $18 each week.
The amount of his savings M depends on the number of weeks elapsed n .
This relationship is represented using the equation M = 18n + 224.
Graphically, how would the line of this relationship change if Cassandra deposited $14 a week?
Please choose an answer.
The line will undergo a downward vertical translation.
The line will undergo a vertical translation upwards.
The inclination of the line will decrease.
The inclination of the line will increase.
Answer:
the inclination of the line will decrease
Step-by-step explanation:
If Cassandra changes the amount she deposits from 18 to 14, the slope changes to 14. So the new equation is M=14n + 224. The 224 is still the same, because that is the initial amount, and the new situation hasn't said anything about changing that, so it will not have any vertical translations. With that being said, as a result the slope will be less, so you can see it as "less vertical", so the inclination of the line will decrease
A princess has two pet dragons. The dragons can eat 300kg of chocolate in 12 days. How many DAYS will the same 300kg last if got 4 more dragons for her birthday?
The chocolate will last for 1 day, if she gets 4 more dragons
How to determine the number of days?The expression can be represented using the following ratio:
Ratio = Dragons : Days : Chocolate
For the 2 dragons she has, we have:
Ratio = 2 : 12 : 300
When she gets 4 more dragons, we have:
Ratio = 6 : days : 300
Equate both ratios
6 : days = 12 : 2
Express as fraction
days/6 = 2/12
Multiply both sides by 6
days = 6 * 2/12
