Step-by-step explanation:
(√3−(−2√3))^2+(−√2−5√2)^2
Subtracting a negative is like adding
(√3+(2√3))^2+(−√2−5√2)^2
Taking the first term
(√3+(2√3))(√3+(2√3))
sqrt(3)^2 +2 sqrt(3) * sqrt(3) +2 sqrt(3) * sqrt(3) + (2 sqrt(3))^2
3 + 2 *3 + 2*3 + 4*3
3 +6+6+12
27
Second term
(−√2−5√2)(−√2−5√2)
-sqrt(2)*-sqrt(2) -sqrt(2)*-5sqrt(2) -sqrt(2)*-5sqrt(2) -5sqrt(2)*(-5sqrt(2))
2 +5*2 +5(2) +25(2)
2+10+10+50
72
Add the two terms together
27+72

Answer:
d = 6(√3 - 2√2)
Step-by-step explanation:
d = (√3 - (-2 √3) * 2 + (-√2 - 5√2) * 2
d = (√3 + 2√3) * 2 + (-√2 - 5√2) * 2
d = 3√3 * 2 + (-6√2) * 2
d = 6√3 + (-12√2)
d = 6√3 - 12√2
d = 6(√3 - 2√2)
Are the numbers 10 and 10% the same? By what percent is the number smaller than the greater one?
Answer:
The way to consider this problem is to realize that the
% symbol actually is equal to a number just like [tex]\pi[/tex] is
whereas [tex]\pi[/tex] is equal to 3.1415... , % is equal to .1 (as a decimal ) or 1/100 as
a fraction... thus
10% is actually 10 * 1/100 or 10/100 which is not 10...
as for the size the 1/100 essentially a DIVISION thus it ends up being SMALLER
Step-by-step explanation:
We can not compare a number and a percentage. 10% of something means 1/10th of something and it can be anything for instance.
What is the percentage?The word percentage comes from the Latin term per centum, which means "by the hundred." In the 16th century, the Latin phrase made its way into English. Later, it was shortened to percent and ended with a period. Later, the period was eliminated, and the two portions were combined to create the current one-word form of a percent.
The best way to approach this issue is to understand the percentage. The % sign actually corresponds to a number. While equals 3.1415, % is equivalent to.1 (as a decimal) or 1/100 as a portion, hence, 10% is actually 10 * 1/100, which is not the same as 10. Regarding size, since 1/100 is essentially a division, it becomes smaller.
Therefore, A number and a percentage cannot be compared. 10% of something is equal to one-tenth of it, and it can be anything, for example.

could anyone help me with this answer ill give brainly but if its correct
Answer:
Linear, positive, strong
Step-by-step explanation:
Association is described as strong (linear) , weak or none(nonlinear).
If you draw a line straight through the points and most of the points are on or near the line then the association is strong. If very few points are near or on the line then the association is weak. If almost none of the points are on the line then there is no association
If you were to draw a line on this graph straight through the points most of the points would be on or near the line therefore there is a strong linear association.
Because the line would be going up and to the right the association would be positive

[tex](x-5)^2+(y+3)^2=10[/tex]
Step-by-step explanation:
equation of a circle: (x – h)^2 + (y – k)^2 = r^2 where (h,k) is the center
The center of the circle is at (5, -3)
(x-5)^2+(y+3)^2
To find the radius, use distance formula: [tex]\sqrt{(x_{1}-x_{2})^2 + (y_{1}-y_{2})^2}[/tex]

find the next three sequence of 1,3, 9, 27,
Answer: 81, 243, 729
Step-by-step explanation:
STEP ONE: Find a pattern in the sequence
3 ÷ 1 = 3
9 ÷ 3 = 3
27 ÷ 9 = 3
As we can see from the given sequence, each number multiplies 3 to get the next term.
STEP TWO: Find the next three terms
27 × 3 = 81
81 × 3 = 243
243 × 3 = 729

the sum of 5 times a number and 8 is equal to 9
Answer:
The unknown number is [tex]\frac{1}{5}[/tex]
Step-by-step explanation:
Let's make the unknown number x.
The sum of 5 TIMES a number (x) & 8 is 9.
Let's write it mathematically.
5x + 8 =9
We are trying to find the unknown number, so let's remove all the numbers from the left side to find x. Minus 8.
5x=1
5x is basically 5 times x, so to find x, we need to divide and from there we can remove 5.
x= [tex]\frac{1}{5}[/tex]

A shipping container is in the shape of a right rectangular prism with a length of 13 feet, a width of 9 feet, and a height of 4 feet. The container is completely filled with contents that weigh, on average, 0.61 pound per cubic foot. What is the weight of the contents in the container, to the nearest pound?
Answer:
285pound
Step-by-step explanation:
Volume of the container = length * width * height
= 13 * 9 * 4
= 468 cubic feet
Weight of the contents in the container = 468 * 0.61 = 285.48 = 285pound

Would the function ƒ(x) = 4 be considered a step function? Explain your reasoning.
Hey there! I'm happy to help!
A step function is a function that looks like stairs when you graph it. Normally the end of one line will be graphed as an open circle (less or greater than, not equal to) while the other end would be a closed circle. This allows for a new line of the function to start directly above it without it not being a function (an input cannot have two outputs)
The function f(x)=4 is just a horizontal line as it has a slope of 0 (there is no x on the right side of the equation), so this doesn't resemble a step function.

Finding x- and y- intercepts
y = 5х – 6
Answer:
Below!
Step-by-step explanation:
X intercept
y = 5x - 6
0 = 5x - 6
-5x = -6
divide both sides by -5
x = 6/5 or 1.2
(1.2, 0)
Y intercept
y = 5x - 6
y = 5(0) - 6
y = -6
(0, -6)
