Answer:
[tex]b=20[/tex]
Step-by-step explanation:
So we have the equation:
[tex]b=(\sqrt{4})^2+4^2[/tex]
The square root and the square cancels out for the first term.
And 4 squared is 16.
So:
[tex]b=4+16[/tex]
Add:
[tex]b=20[/tex]
Answer: 20
Solution Steps

sqrt4^2+42
Calculate 4 to the power of 2 and get 16.
sqrt16+4^2≈20
Calculate the square root of 16 and get 4.
4+4^2≈20
Calculate 4 to the power of 2 and get 16.
4+16=20
Add 4 and 16 to get 20.

The term "elevation" is often used to describe the height of a place (such as a city, a mountain, or a valley) compared to sea level. For example, the city of Houston, Texas has an elevation of 105 feet. The surface of the sea has an elevation of 0 feet. Some places are below sea level, so their elevations are negative values. Two towns have different elevations, but when the elevations are used as inputs of , they both produce an output of 25. Why do they produce the same output?
Answer:
obviously they will produce same output because the elevation of object and image will be same
The vertex of this parabola is at 2, -1 When the y-value is 0 the x value is 5 what is the coefficient of the squared term in the parabola equation.
A. -3
B. -4
C. 4
D. 3
Answer:
[tex]\large \boxed{\sf \frac{1}{9}}[/tex]
Step-by-step explanation:
[tex]\sf y=a(x-h)^2+k[/tex]
[tex]\sf Vertex = (h,k)[/tex]
y-value is 0 and the x value is 5
h = 2
k = -1
[tex]\sf 0=a(5-2)^2+-1[/tex]
Solve for [tex]\sf a[/tex] (the coefficient of the squared term).
[tex]\sf 0=a(3)^2+-1[/tex]
[tex]\sf 0=9a-1[/tex]
[tex]\sf 9a=1[/tex]
[tex]\displaystyle \sf a=\frac{1}{9}[/tex]
The coefficient of the squared term in the parabola equation is 1/9.
Answer:
Fot this parabola the coefficient for squared term is 7
Step-by-step explanation:
The formula for vertex equation is:
x = a*(y-h)^{2}+kx=a∗(y−h)
2
+k
if vertex is at (-3,-1) and in the formula the vertex is (k,h), we replace this values
x = a*(y +1)^{2} -3x=a∗(y+1)
2
−3
The other point of this parabola is (4,0), so we replace it in the formula below:
4 = a*(0 + 1)^{2} -34=a∗(0+1)
2
−3
4 = a*(1)-34=a∗(1)−3
4 +3= a*(1)4+3=a∗(1)
a=7a=7
A number is decreased by seven. Then, the new number is multiplied by 3 to get an answer of -9. What is the original number? A. -4 B. -30 C. 4 D. 30
Answer:
The answer is c
Step-by-step explanation:
You have to do everything backwards,
-9 divide it by 3 to get -3, then add seven to that answer
Answer:
C
Step-by-step explanation:
You can work backward to find out the answer!
Start with -9. Instead of multiplying by 3, you can divide.
-9/3 = -3
Now, instead of decreasing -3 by 7, increase by 7.
-3+7 = 4
You get 4, which is C!

Hannah was adding 5 plus -4. When explaining her work she said that the sum is 9 because you add the numbers and take the sign of the larger number. In complete sentences explain what Hannah got wrong. What should the correct answer be?
Answer:
The sum is 1
Step-by-step explanation:
When you add a negative number to a positive number, it is basically just subtracting the negative from the positive. To make it simple, 5 + -4 is just 5 - 4.
Hannah was wrong in saying you take the sign of the larger number because it would not matter if the first number was a million, the signs don't change based on the size of numbers.

what is the doors width in simplest form
Answer:
x + 6
Step-by-step explanation:
From the question given above, the following data were obtained:
Length of rectangle = 3x + 6
Width of rectangle = 4x – 1
Width of door =..?
A careful observation of the diagram shows that the door is located along the length of rectangular room.
In a rectangle, two sides are equal. Therefore,
x + door + x = 3x + 6
Making door subject of the above formula, we have:
x + door + x = 3x + 6
door + x + x = 3x + 6
door + 2x = 3x + 6
Subtract 2x from both side
door + 2x – 2x = 3x + 6 – 2x
door = 3x – 2x + 6
door = x + 6
Therefore, the width of the door is x + 6

We can calculate the depth d of snow, in centimeters, that accumulates in Harper's yard during the first h hours of a snowstorm using the equation d=5hd, equals, 5, h. How many hours does it take for 1 centimeter of snow to accumulate in Harper's yard? How many centimeters of snow accumulate per hour?
Answer:
a) 0.2 h
b) 5 cm
Step-by-step explanation:
The given equation is:
[tex] d = 5h [/tex] (1)
Where:
d: is the depth in centimeters
h: is the time in hours
a) The hours that takes for 1 cm of snow to accumulate in Harper's yard can be found by solving equation (1) for h and by entering d = 1 cm into the equation:
[tex]h = \frac{d}{5} = \frac{1}{5} = 0.2 h[/tex]
Hence, it takes 0.2 hours for 1 centimeter of snow to accumulate in Harper's yard.
b) The depth in centimeters of snow accumulate per hour is:
[tex] d = 5h = 5*1 = 5 cm [/tex]
Therefore, 5 cm of snow accumulates per hour.
I hope it helps you!

Answer:
The sum of a number and 10 is equal to three times that number.
Step-by-step explanation:
Break the parts down and put them together.
The sum of a number and 10: 'g + 10'

if this cylindrical vase were filled with water. approximately how much water would it contain? A. 63in^3 B. 126in^3 C. 251in^3 D. 503in^3
Answer:
126 in³
Step-by-step explanation:
Given a cylindrical vase having a diameter (d) of 4 in, and an height (h) of 10 in, the amount of water it would contain can be calculated using:
Volume of cylinder = πr²h
Where,
r = radius = ½ of d = ½*4 = 2 in
h = height = 10 in
Take π as 3.14
Plug in the values into the formula
Volume = 3.14*2²*10 = 3.14*4*10 = 125.6 ≈ 126 in³

The solution to this is x ≤ 4.
So then we look at the graphs and choose the correct one.
When the sign is ≤ it's like an arrow whatever way it's pointing it goes that way. In this case it'd go the other way even though the sign is ≤, because the solution is stating 4 is greater then or equal to so it can't be less than 4. And the only option of +4 and higher is C.

Please help me asap.
===============================================
Let a,b,c,d be scalars.
In general if v and w are two vectors such that
v = <a, b>
w = <c,d>
then the difference of the two vectors is
v - w = <a-c, b-d>
so we subtract the coordinates
-----------------
Using that idea for the given vectors leads to
v = <9, -1>
w = <-1, -6>
v - w = <9 - (-1), -1-(-6)>
v - w = <9+1, -1+6>
v - w = < 10, 5 >
the number of diagonals that can be drawn in a opolygon of n sides is 1/2n(n-1)-n. If 230 diagonsaals can be drawn how many sides does the polygon have'
Answer:
n = 20
Step-by-step explanation:
The number of diagonal that can be drawn in a polygon of n sides is given by :
[tex]D=\dfrac{n(n-3)}{2}[/tex]
If the number of diagonals are 230, then put D = 230 in above formula. So,
[tex]230=\dfrac{n(n-3)}{2}\\\\460=n^2-3n\\\\n^2-3n-460=0[/tex]
It is a quadratic equation, the value of n is equal to 20.
It means that for 230 diagonal, there are 20 sides of the polygon.

Step-by-step explanation:
2m is term because it is what you are looking for
In the expression 4(2m-n), (2m-n). is a term and In expression 4(2m-n), 2m is also a term. The correct options are B and B for both.
What is a term in an expression?One mathematical expression makes up a term. It could be a single variable (a letter), a single number (positive or negative), or the number of variables multiplied but never added or subtracted.
Variables in certain words have a number in front of them. A term is defined as a single number or single variable or number and variable multiplying with each other in a mathematics expression.
The first expression is 4(2m-n), then in the expression 2m - n will be the term of the expression.
The second expression is 4(2m-n), then in the expression 2m is the term of the expression.
Therefore, the expression 4(2m-n), (2m-n). is a term and In expression 4(2m-n), 2m is also a term.

Subtract 120 from each side
150-120 = ?
30 = ?
Answer:
[tex]\huge\boxed{<SUT = 30\ degrees}[/tex]
Step-by-step explanation:
According to exterior angle theorem:
The measure of the exterior angle is equal to the sum of non-adjacent interior angles.
So,
