Answer:
hey I believe standard form would look like this: f(x) = a(x - h)^2 + k
this is regular form f(x)=ax^2+bx+c or something like x^2+4x+4.
I think H and K are the vertex
hope this is close to what your looking for.
Step-by-step explanation:
I think it's x^2+6x-18

1.) What is the surface area of the figure below?
Answer:
Step-by-step explanation:
length (l) = 3 ft
Width (w) = 3 ft
Height (w) = 6 ft
Surface area = 2*( lw + wh + hl)
= 2* (3*3 + 3*6 + 6*3)
= 2*(9 + 18 + 18)
= 2 * 45
= 90 square ft

Please help sorry I’m dumb
There is a point $A$ with positive coordinates such that the sum of the coordinates of $A$ is $14$. If the $x$-coordinate of $A$ is $a$, then point $P$ is at $(3a, a^2+13a-11)$. If the slope of a line passing through $A$ and $P$ is $7$, find $a$.
Answer:
The x-coordinate of A is:
a = 6.1
Step-by-step explanation:
For point A:
x-coordinate = a
x-coordinate + y-coordinate = 14
y-coordinate = 14 - x-coordinate
y-coordinate = 14 - a
So point A can be written as (a, 14-a)
Let (a,14) be (x₁,y₁)
Point P can be written as (3a, a²+13a-11)
Let P be (x₂,y₂)
Slope of a line passing through 2 point is given as:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
where m=7
Substitute all values
[tex]7=\frac{(a^2+13a-11)-(14-a)}{3a-a}\\7=\frac{a^2+13a-a-11-14}{3a-a}\\7=\frac{a^2+12a-25}{2a}\\14a=a^2+12a-25\\a^2-2a-25=0\\a=6.1,a=-4.1[/tex]
As A has only positive coordinates
a = 6.1

Answer:
x=-4
Step-by-step explanation:
Ohhh you wrote 4 on the other post, not 4x.
Okay.
6(x+3)-4x=10
6x+18-4x=10
2x=-8
x=-4
Answer:
The value of [tex]x[/tex]:
[tex]x = -4[/tex]
Step-by-step explanation:
Solve for [tex]x[/tex]:
[tex]6(x+3) - 4x = 10[/tex]
Use Distributive Property:
[tex]6(x+3) - 4x = 10[/tex]
[tex]6x + 18 - 4x = 10[/tex]
Combine [tex]6x[/tex] and [tex]-4x[/tex] together:
[tex]6x + 18 - 4x = 10[/tex]
[tex]2x + 18 = 10[/tex]
Subtract both sides by [tex]18[/tex]:
[tex]2x + 18 - 18 = 10 -18[/tex]
[tex]2x = -8[/tex]
Divide both sides by [tex]2[/tex]:
[tex]\frac{2x}{2} = \frac{-8}{2}[/tex]
[tex]x = -4[/tex]
So, therefore, the final answer is [tex]x = -4[/tex] .
Consider triangle DEF. The legs have a length of 36 units
What is the length of the hypotenuse of the triangle
18 units
1872 units
36 units
36/7 units
Answer:
[tex]\large \boxed{36\sqrt{2}\text{ units}}[/tex]
Step-by-step explanation:
Assume ∆DEF looks like the one below.
We can use Pythagoras' Theorem to find the hypotenuse f.
[tex]\begin{array}{rcl}d^{2} + e^{2} & = & f^{2}\\36^{2} + 36^{2} & = & f^{2}\\f^{2} & = & 2 \times 36^{2}\\f & = & \sqrt{2 \times 36^{2}}\\& = & 36\sqrt{2}\\\end{array}\\\text{The length of the hypotenuse is $\large \boxed{\mathbf{36\sqrt{2}}\textbf{ units}}$}[/tex]

How does the graph of y= Vx+2 compare to the graph of the parent square root function?
The graph is a horizontal shift of the parent function 2 units right.
The graph is a horizontal shift of the parent function 2 units left.
The graph is a vertical shift of the parent function 2 units up.
The graph is a vertical shift of the parent function 2 units down.
Answer:
a) The graph is a horizontal shift of the parent function 2 units right.
Step-by-step explanation:
Explanation:-
Type of transformation Change to co-ordinate point
Vertical translation up 'd' units (x,y) →(x ,y+d)
Vertical translation down 'd' units (x,y) →(x ,y- d)
Horizontal translation left 'c' units (x,y) →(x-c ,y)
Horizontal translation right 'c' units (x,y) →(x+c ,y)
Reflection over X-axis (x,y) →(x ,-y)
Reflection over y-axis (x,y) →(-x ,y)
Given graph f(x) = √x
The graph is a Horizontal shift of the parent function '2' units right
Therefore the transformation of the graph [tex]y = \sqrt{x+2}[/tex]

could you use the formula for the surface area of a rectangular prism to find the surface area of a cube explain please help me.
Answer:
You can use our formula for the surface area of a rectangular prism for a cube as well. A cube is a rectangular prism where all its sides are the same. The formula to find the surface area of a rectangular prism is A = 2wl + 2lh + 2hw, where w is the width, the l is the length, and the h is the height.
Find the value of x in the triangle
Answer:
x =3.

3x = 9
x = 3.
Answer:
49 and 2/3
Step-by-step explanation:
3x+2+18+11=180

3.
Nime

1
4.
2
Answer:
The value of x is -2.
Step-by-step explanation:
First, you have to eliminate the brackets by expanding :
[tex]2(x - 4) = 4(2x + 1)[/tex]
[tex]2x - 8 = 8x + 4[/tex]
Next, you have to move all the like-terms to one side :
[tex]2x - 8 - 8x = 4[/tex]
[tex] - 6x = 4 + 8[/tex]
[tex] - 6x = 12[/tex]
[tex]x = 12 \div ( - 6)[/tex]
[tex]x = - 2[/tex]
Answer:
[tex]x = - 2[/tex]
Step-by-step explanation:
[tex]2(x - 4) = 4(2x + 1) \\ 2x - 8 = 8x + 4 \\ 2x - 8x = 8 + 4 \\ - 6x = 12 \\ \frac{ - 6x}{ - 6} = \frac{12}{ - 6} \\ x = - 2[/tex]

Please Help Me. Work must be shown for this problem. Solve for x. Round answers to the nearest hundredth (2 decimal places).
Answer:
About 188.71 feet
Step-by-step explanation:
The cosine of an angle is equivalent to the adjacent side divided by the length of the hypotenuse. Therefore:
[tex]\cos 58=\dfrac{100}{x} \\\\x=\dfrac{100}{\cos 58}\approx 188.71[/tex]
Hope this helps!
Answer:
x = 188.71
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos theta = adjacent/ hypotenuse
cos 58 = 100/x
Multiply by x
x cos 58 = 100
Divide by cos 58
x = 100/cos 58
x =188.7079915
To the nearest hundredth
x = 188.71
