the distance between the point 0,0 and 5, 12
Answer:
13
Step-by-step explanation:
the formula for distance is √(X2-X1)^2 + (y2-y1)^2
=√(5-0)^2 + (12-0)^2
=√5^2 + 12^2
=√25+144
=√169

When using a regression equation, the difference between the formulas used to calculate the confidence interval estimate and prediction interval estimate is ______.
Answer:
the addition of "1" to the quantity under the radical sign.
Step-by-step explanation:
Using a regression equation :
The confidence interval is obtained using the relation :
yhat ± t(α/2) * s√(1/n + (Xp - xbar)²/SSx)
yhat = Predicted value
s = estimated standard deviation of yhat
x = Xp
The prediction interval is obtained using the relation :
yhat ± t(α/2) * s√(1 + 1/n + (Xp - xbar)²/SSx)
Hence, from the formula stated abibeb, we can see that, the only difference is the 1 added to the prediction interval formula.

Answer:
maximum: 16minimum: -24Step-by-step explanation:
The attache graph shows the solution region is bounded by lines through the points (-2, 4), (6, 0), and (3, -6).
The solution (x, y) = (-2, 4) gives the maximum value of z: 16.
The solution (x, y) = (3, -6) gives the minimum value of z: -24.

Answer:
Polynomials are expressions with one or more terms with a non-zero coefficient. A polynomial can have more than one term. In the polynomial, each expression in it is called a term.
Solution given:
1:x²-5x+6
let
f(x)=x²-5x+6
It is polynomial in one variable x
According to definition of variable
f(x)=0
substituting value of f(x)
x²-5x+6=0
Doing middle term factorisation
6=3*2*1
remember that in front of constant term is positive sigh
so we need to add factor of 6 to get 5
I.e. 3+2=5
substituting (3+2) in place of 5
x²-(3+2)x+6=0
x²-3x-2x+6=0
taking common from each two term
x(x-3)-2(x-3)=0
again taking common
(x-3)(x-2)=0
either
x-3=0
x=3or
x-2=0
x=22:
4x³-3x²+2
let
f(x)=4x³-3x²+2
It is polynomial in one variable x.
According to definition of variable
f(x)=0
we cannot solve it by factoring so solving by graph

I cannot solve the equation.
√(7d+1)-4=11
Answer:
I believe the answer is d = 32
Step-by-step explanation:
You should isolate the radical, then raise each side of the equation to the power of its index.
9514 1404 393
Answer:
d = 32
Step-by-step explanation:
Add 4, then square, and solve the resulting linear equation.
√(7d +1) = 15
7d +1 = 225 . . . . . . square both sides
7d = 224 . . . . . . . . subtract 1
d = 32 . . . . . . . . . . divide by 7

Which of the following expressions are equivalent to -3x- 6/10
Choose all that apply:
A=3/6x1/10
b=- 3/10x-6
c= none of the above
Answer:
c= none of the above
Step-by-step explanation:

This has two separate terms, a term with a variable
-3x and a term with a constant -6/10
A=3/6x1/10 This has only one term
b=- 3/10x-6 This has a different x term -3/10 which is not -3

A box of tangerines that weighs 5 pounds costs $4.25.
What is the cost per pound?
Answer:
$0.85
Step-by-step explanation:
$4.25 divided by 5 pounds equals $0.85 per pound.
Answer:
$0.85
Step-by-step explanation:
Find the unit rate.
4.25/5=x/1
Solve for x. X= 4.25/5=0.85
So 1 lb of tangerines costs $0.85.

Find a polar equation for the curve represented by the given Cartesian equation. (Use t in lieu of θ in your answer.) x2+y2=8cx
Answer:
The polar equation of the curve is:
[tex]r=8c*cos(\theta)[/tex]
Step-by-step explanation:
In polar form x and y could be written as:
[tex]x=rcos(\theta)[/tex]
[tex]y=rsin(\theta)[/tex]
Taking the square of each value we have:
Let's recall that [tex]cos^{2}(\theta)+sin^{2}(\theta)=1[/tex]
[tex]x^{2}+y^{2}=r^{2}(cos^{2}(\theta)+sin^{2}(\theta))[/tex]
[tex]x^{2}+y^{2}=r^{2}[/tex]
Then, the cartesian equation is rewritten as:
[tex]x^{2}+y^{2}=8cx[/tex]
[tex]r^{2}=8c*rcos(\theta)[/tex]
Therefore, the polar equation of the curve is:
[tex]r=8c*cos(\theta)[/tex]
I hope it helps you!

Boat A leaves a dock headed due east at 2:00PM traveling at a speed of 9 mi/hr. At the same time, Boat B leaves the same dock traveling due south at a speed of 15 mi/hr. Find an equation that represents the distance d in miles between the boats and any time t in hours.
Answer: [tex]17.5t[/tex]
Step-by-step explanation:
Given
Speed of boat A is [tex]v_a=9\ mi/hr[/tex]
Speed of boat B is [tex]v_b=15\ mi/hr[/tex]
Both are moving perpendicular to each other
Distance traveled by Boat A [tex]x_a=9t[/tex]
Distance traveled by Boat B [tex]x_b=15t[/tex]
Distance between them is given by Pythagoras theorem
[tex]\Rightarrow d^2=(x_a)^2+(x_b)^2\\\\\Rightarrow d^2=(9t)^2+(15t)^2\\\\\Rightarrow d=\sqrt{(9t)^2+(15t)^2}\\\\\Rightarrow d=\sqrt{81t^2+225t^2}\\\\\Rightarrow d=\sqrt{306t^2}\\\\\Rightarrow d=17.49t\approx 17.5t\ \text{miles}[/tex]
Distance between them is [tex]17.5t[/tex]

Answer:
$1487.50
Step-by-step explanation:
9514 1404 393
Answer:
$1487.50
Step-by-step explanation:
The amount of interest due is ...
I = Prt
where P is the loan amount, r is the annual rate, and t is the number of years. Here, t = 6 months = 1/2 year, so the interest due is ...
I = $1400×0.125×1/2 = $87.50
The total amount due is the sum of the loan amount and the interest:
due = $1400 +87.50 = $1487.50
The total amount due after 60 months is $1487.50.
Write an equation for a function y=square root of x then shifted up 8 units

x square rooted is x^2 and shifted up 8 unit probably means that it wants the y-intercept to be 8.
twelve people enter a contest. prizes will be given for first second and third place. how many ways can the prizes be given
Answer:
1320 ways
Step-by-step explanation:
Number of contestants = 12
Positions that are n be awarded = First, Second, Third
Number of contestants who could be first = 12 (all 12 contestants)
Number of contestants who could be second = 11 (all 12 contestants - first)
Number of contestants who could be third = 10 (all 12 contestants - first and second )
The number of ways prices can be given :
(1st * 2nd * 3rd) = 12 * 11 * 10 = 1320 ways

Find the sum of the arithmetic series given a1=9, d=3, and n=14.
A. 797
B. 399
C. 1594
D. 798
Answer:
B) 399
Step-by-step explanation:
We want to find the sum of the arithmetic series given that:
[tex]a_1=9, \, d = 3, \text{ and } n = 14[/tex]
In other words, we want to find the sum of the first 14 terms of the series when the first term is 9 and the common difference is 3.
Recall that the sum of an arithmetic series is given by:
[tex]\displaystyle S = \frac{n}{2}\left(a + x_n\right)[/tex]
Where n is the amount of terms, a is the first term, and xₙ is the nth or last term.
We will need to find the last term. We can write a direct formula. The general form of a direct formula is given by:
[tex]x_n=a+d(n-1)[/tex]
Since the initial term is 9 and the common difference is 3:
[tex]x_n=9+3(n-1)[/tex]
Then the 14th or last term is:
[tex]\displaystyle x_{14}=9+3((14)-1)=9+39=48[/tex]
Then the sum of the first 14 terms is:
[tex]\displaystyle \begin{aligned} S_{14} &= \frac{14}{2}\left(9+48\right) \\ \\ &= 7(57) \\ \\ &= 399\end{aligned}[/tex]
Our answer is B.
Can you add 5 xy + 4 yx
Answer: Yes, we can add them as they are like terms
The answer we get after adding is 9xy
Step-by-step explanation:
Even though 'xy' and 'yx' seem to be different, we must remember that multiplication is commutative and hence 'xy' and 'yx' are the same
The answer we get after adding is 9xy
Answer:
Yes, and you get 9xy
Step-by-step explanation:
4yx = 4xy
Yes, you can add them.
5xy + 4xy = 9xy
