Answer:
y=4/3x+19/3
Step-by-step explanation:
perpendicular = slope is the negative reciprical.
plug in the point (-4,1) for (x,y)
1(y)=4/3(-4)+b
1=-16/3+b
b=19/3

A field hockey field is rectangular. Its width is 54.88 meters, and its perimeter is 289.76 meters. Find the length of the field.
Answer:
90 PLEASE MARK ME BRAINLLIEST
Step-by-step explanation:
289.76-54.88-54.88=180/2=90
Perimeter is the sum of the length of the sides used to make the given figure. The length of the field is 90 meters.
What is the perimeter?Perimeter is the sum of the length of the sides used to make the given figure.
Given that the width of the field is 54.88 meters and the perimeter of the field is 289.76 meters. Therefore, we can write the perimeter as,
Perimeter = 2(Length + Width)
289.76 meters = 2(Length + 54.88 meters)
289.76meters / 2 = Length + 54.88 meters
144.88metes = Length + 54.88 meters
Length = 144.88 meters - 54.88 meters
Length = 90 meters
Hence, the length of the field is 90 meters.

Ann has two coupons for a chair.
Coupon A:
Coupon B:
35% off of a $55 chair
$22 rebate on a $55 chair
Choose the coupon that gives the lower price.
Then fill in the blank with the correct value.
Answer:Coupon B gives the lower price. The price of coupon B is $4.4 less than the price of coupon A.
Step-by-step explanation:
The coupon B gives the lower price. That means by using coupon B, Ann will get a chair at $33.
The price with coupon B is $2.75 less than the price with coupon A.
What is coupon?A coupon is a ticket or document that can be redeemed for a financial discount or rebate when purchasing a product.
What is percentage?A percentage is a proportion that shows a number as parts per hundred
How to convert percentage into a number?To convert a percent into a number divide the given percentage by hundred and remove the percentage sign.
According to the given question.
Ann has two coupon for a Chair.
Coupon A is giving 35 percent off on a chair of $55.
And, coupon B is giving $22 0ff on chair 0f $55
If Ann uses coupon A then the amount she have to pay for chair is given by
Amount = [tex]55-\frac{35}{100} ($55)[/tex]
Amount = [tex]55-0.35(55)[/tex]
Amount = [tex]55-19.25[/tex]
Amount = $35.75
If Ann uses coupon B then the amount she have to pay for chair is given by
Amount = $55 - $22
Amount = $33
Hence, the coupon B gives the lower price. That means by using coupon B, she will get a chair at $33.
Since, through coupon A the amount she have to pay is $35.75 and through B she have to pay the amount of $33.
Now, $35.75 - $33 = $2.75
Thus, the price with coupon B is $2.75 less than the price with coupon A.

A scooter travels 30 feet in 2 seconds at a constant speed.
The distance the scooter travels in 1 second is
feet. The distance the scooter travels in 3 seconds is
feet. The distance the scooter travels in 4 second is
feet. The distance the scooter travels in 5 second is
feet.
Answer:
The scooter travels 15 feet in 1 second
The scooter travels 45 feet in 3 seconds
The scooter travels 60 feet in 4 seconds
The scooter travels 75 feet in 5 seconds
Step-by-step explanation:
First, let's find the number of feet the scooter travels in 1 second
(30 : 2) ÷ 2 = 15 : 1
Now that we have the unit rate, we can easily find the answers to the other questions.
(15 : 1) x 3 = 45 : 3
(15 : 1) x 4 = 60 : 4
(15 : 1) x 5 = 75 : 5

Which is one of the transformations applied to the graph of f(x)=x2 to change it into the graph of g(x) = -x2 + 16x – 44?
The graph of f(x) = x2 is widened.
The graph of f(x) = x2 is shifted left 8 units. O
The graph of f(x) = x2 is shifted down 44 units.
The graph of f(x) = x2 is reflected over the x-axis.
Answer:
Only option D is one of the transformations needed.
Step-by-step explanation:
The graph of f(x)=x^2 is a positive parabola with x=0 as the zero in ordinates and also 0 as a zero x. This is, the graph passes in (0,0) and this is the only point it crosses both axis, then for every x value we will gave a positive f(x).
Here I attach a graph that shows both, f(x)=x^2 and g(x)=-x^2+16x-44.
As you can see, for transforming f(x) in g(x) we need to reflect it over the x axis, as g is open downwards. Then, as the quadratic term is still being x^2 we do not wide it (as you see in the graph both curves are equally widened).
Then, we can also see that the graph is shifted right, so we do not shift it left 8 units (notice that we shift it right 8 units).
So, after reflecting over the x axis and shifting right we need to shift it UP, as we can see the graph is over the x axis.
So, the three transformations needed are:
1. reflect over the x axis
2. shift right 8 units
3. shift up 20 units.
So, from the options you proposed we chose only d, to which we MUST add the transformations noted above.
Sorry for the mistake!
Answer:

Step-by-step explanation:
The size of one interior angle of a regular n-gon is ...
interior angle = 180° - 360°/n
For n=12, this measure is ...

interior angle = 150°

If A is the area of a circle with radiusr and the circle expands as time passes, find dA/dt in terms of dr/dt.
So I have, A= π r2
dA/dt = 2π r (dr/dt)
Answer:
[tex]\frac{dA}{dt} = 2\pi r(\frac{dr}{dt})[/tex]
Step-by-step explanation:
Your solution is correct (See explanation):
Area (A) of a circle is
[tex]A = \pi r^2[/tex]
Where
[tex]r = radius[/tex]
Differentiate both sides with respect to t
[tex]\frac{dA}{dt} = 2\pi r(\frac{dr}{dt})[/tex]
This is so because, we have to differentiate A on the left hand side and r on the right hand side because [tex]2\pi[/tex] is a constant
Hence, your solution is correct and and
[tex]\frac{dA}{dt} = 2\pi r(\frac{dr}{dt})[/tex]

Answer:
Yes, this is a function.
No, this is not a linear function.
Step-by-step explanation:
A function is a process or a relation that associates each element x of a set X, the domain of the function, to a single element y of another set Y
Linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx. A linear function has one independent variable and one dependent variable.

Solving Absolute Value Inequalities. As we know, the absolute value of a quantity is a positive number or zero.

) How many degrees of freedom are available for hypothesis tests and confidence intervals for single regression coefficient
Answer:
We use students' t distribution therefore degrees of freedom is v= n-2
Step-by-step explanation:
Confidence Interval Estimate of Population Regression Co efficient β.
To construct the confidence interval for β, the population regression co efficient , we use b, the sample estimate of β. The sampling distribution of b is normally distributed with mean β and a standard deviation σ.y.x / √(x-x`)². That is the variable z = b - β/σ.y.x / √(x-x`)² is a standard normal variable. But σ.y.x is not known so we use S.y.x and also student's t distribution rather than normal distribution.
t= b - β/S.y.x / √(x-x`)² = b - β/Sb [Sb = S.y.x / √(x-x`)²]
with v= n-2 degrees of freedom.
Consequently
P [ - t α/2< b - β/Sb < t α/2] = 1- α
or
P [ b- t α/2 Sb< β < b+ t α/2 Sb] = 1- α
Hence a 100( 1-α) percent confidence for β the population regression coefficient for a particular sample size n <30 is given by
b± t α/2 Sb
Using the same statistic a confidence interval for α can be constructed in the same way for β replacing a with b and Sa with Sb.
a± t α/2 Sa
Using the t statistic we may construct the confidence interval for U.y.x for the given value X0 in the same manner
Y~0 ± t α/2(n-2) SY~
Y~0= a+b X0
