A four-digit perfect square number is created by placing two positive two-digit perfect square numbers next to each other. What is the four-digit square number?
Answer:
1681
Step-by-step explanation:
In a four digit perfect square, the first two digits and last two digits taken seperately are also perfect squares.
Therefore, the answer is 1681 because 1681=41*41 and
16=4*4 and 81=9*9
Number 7 thanks ASAP ASAP
Answer:
Price is $1088 (agrees with answer B)
Step-by-step explanation:
Notice that the linear equation that represents this relationship can be estimated via finding the slope and y-intercept using a couple of the given points on the plane (for example (5, 140), and (10, 200), which results in;
Price = 12 x + 80
where "x" is the number of computers shipped.
Then, to ship 84 computers, we have the following price:
Price = 12 (84) + 80 = 1088
Then the price is $1088.
what is ─7 ─ 4b = ─5b sovled for the variable
Answer:
b = 7
Step-by-step explanation:
Add 4b to both sides
You then get -b = -7
You want to multiply both sides by -1 because you can't have a negative variable
Answer:
b = 7

Standard form of a line that has a slope of -1 and passes through (-5,-1)
Step-by-step explanation:
y + 1 = -(x+5)
y + 1 = -x - 5
y = -x - 6
x + y = -6

Jason wants to solve the following system using the elimination method:
x + 3y = 10
2x + y = 5
What number should the equation 2x + y = 5 be multiplied by to eliminate y?
a. 2
b. -3
c. -2
d. 3
Answer:
No single Correct answer. Both b and d will work
Step-by-step explanation:
You want to get rid of y.
The first equation has a 3 in front of the y
Therefore you would have to multiply the second equation by 3 or - 3
If you use -3 you would add the two equations
If you use 3 you would subtract the two equations.
It is either b or d. Both will give you the same answer.
- Three
x + 3y = 10
-6x - 3y = - 15 Add
-5x = - 5 Divide by - 5
x = -5/-5
x = 1
+ Three
x + 3y = 10
6x + 3y = 15 Subtract
-5x = - 5
x = -5/-5
x = 1 Same thing.

Answer:1+3=4 4+2=6 5+6=11
Step-by-step explanation:
Answer:
1+3=4, 2+4=6, 5+6=11
Step-by-step explanation:
when made into a cube, (assuming 2 is on the top,) 1 is on the left side and 3 is on the right. 2 is on the top and 4 is on the bottom. 5 is on the north side (the front I guess, but north is the way I can explain it best) and 6 is on the south (the back).
Find the regression equation, letting the first variable be the predictor (x) variable. Find the best predicted Nobel Laureate rate for a country that has 78.8 Internet users per 100 people. How does it compare to the country's actual Nobel Laureate rate of 2 per 10 million people
The table is missing, so i have attached it.
Answer:
Regression equation is;
y = 0.2028x - 8.443
The predicted value is not at all close to the actual novel rate
Step-by-step explanation:
The internet users will be the x-values while the novel laureates will be the y-values.
Thus, sum of x values is;
Σx = 79.5 + 79.6 + 56.8 + 67.6 + 77.9 + 38.3 = 399.7
Sum of y values is;
Σy = 5.5 + 9 + 3.3 + 1.7 + 10.8 + 0.1
Σy = 30.4
Σx² = 79.5² + 79.6² + 56.8² + 67.6² + 77.9² + 38.3²
Σx² = 27987.71
Σy² = 5.5² + 9² + 3.3² + 1.7² + 10.8² + 0.1²
Σy² = 241.68
Σxy = (79.5 × 5.5) + (79.6 × 9) + (56.8 × 3.3) + (67.6 × 1.7) + (77.9 × 10.8) + (38.3 × 0.1)
Σxy = 2301.16
The regression line will be;
y = b1(x) + b0
b1 is expressed as;
b1 = [nΣxy - (Σx • Σy)]/[nΣx² - (Σx)²]
Where n is number of given data which is n = 6.
Thus;
b1 = [(6 × 2301.16) - (399.7 × 30.4)]/[(6 × 27987.71) - (399.7)²]
b1 = 1656.08/8166.17
b1 = 0.2028
b0 is expressed as;
b0 = [(Σy • Σx²) - (Σx • Σxy)]/[nΣx² - (Σx)²]
b0 = [(30.4 × 27987.71) - (399.7 × 2301.16)]/[(6 × 27987.71) - (399.7)²]
b0 = -68947.268/8166.17
b0 = -8.443
Thus, regression equation is;
y = 0.2028x + (-8.443)
y = 0.2028x - 8.443
Best predicted value is given as;
y¯ = (Σy)/n
y¯ = 30.4/6
y¯ = 5.067 per 10 million people.
The predicted value is far greater than the actual value of 2 per 10 million people.
Thus, we can say that the predicted value is nowhere close to the actual value

What is the domain of the square root function graphed below?
Answer:
The domain of the graph must be [tex]x\ge \:-4[/tex].
Therefore,
[tex]x\ge \:-4\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\ge \:-4\:\\ \:\mathrm{Interval\:Notation:}&\:[-4,\:\infty \:)\end{bmatrix}[/tex]
Hence, option a is true.
Step-by-step explanation:
From the graph, it is clear that the graph is heading towards positive infinity from x=-4.
The point x=-4 is included in the graph as the starting point of the graph i.e. x=4 is showing a closed circle on x=4, and heading towards positive infinity onward.
i.e. [-4, ∞)
Hence, the domain of the graph must be [tex]x\ge \:-4[/tex].
Therefore,
[tex]x\ge \:-4\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\ge \:-4\:\\ \:\mathrm{Interval\:Notation:}&\:[-4,\:\infty \:)\end{bmatrix}[/tex]
Hence, option a is true.

Answer:
x = 18
y = 54
Step-by-step explanation:
90 - 72 = 18
18 + 2x = 3x
18 = x
2(18) = 36
3(18) = 54
72 + y + 54 = 180
126 + y = 180
y = 54

Which is the height of the lighthouse?
Answer:
Step-by-step explanation:
tan 26° = [tex]\frac{x}{90}[/tex] ⇒ x = 90tan26° ≈ 43.9 ft. (This answer for the picture)
sin 26° = [tex]\frac{h}{100}[/tex] ⇒ h = 100sin26° ≈ 43.9 ft (This answer for the text)
h = √(100² - 90²) ≈ 43.589 ft. (Pythagorean theorem)
2x+7y=1
y=4x−8
Is (4,8)(4,8)left parenthesis, 4, comma, 8, right parenthesis a solution of the system?
hello :
2x+7y=1 ...(*)
y=4x−8...(**)
(4;8) means x= 4 and y= 8
put this values in (*) and(**) :
2(4)+7(8) =1 62=1 false
8=4(4)-8 8=8 true
so :(4;8) is not solution for this system.
