[tex]\large\boxed{X=\sqrt{12}\ in=2\sqrt3\ in}[/tex]
Step-by-step explanation:
ΔADC and ΔCBD are similar. Therefore the corresponding sides are in proportion:
[tex]\dfrac{AD}{CD}=\dfrac{CD}{DB}[/tex]
We have
AD = 2, CD = X, DB = 6.
Substitute:
[tex]\dfrac{2}{X}=\dfrac{X}{6}[/tex] cross multiply
[tex]X^2=(2)(6)\\\\X^2=12\to X+\sqrt{12}[/tex]

What is the sum of the arithmetic series below 2+5+8+...+56
Answer:
551
Step-by-step explanation:
The sum to n terms of an arithmetic sequence is
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex]( first + last)
The number of terms is
[tex]a_{n}[/tex] = a + (n - 1)d ← d is the common difference, a is the first term
d = 5 - 2 = 8 - 5 = 3, hence
2 + 3(n - 1) = 56
2 + 3n - 3 = 56
3n - 1 = 56 ⇒ 3n = 57 ⇒ n = 19
[tex]S_{19}[/tex] = [tex]\frac{19}{2}[/tex] ( 2 + 56 ) = 19 × 29 = 551
If a = 5i - 6j and b = -2i + 4j , find -3a + 2b
Answer:
-19i + 26j
Step-by-step explanation:
-3 (5i - 6j) + 2 (-2i + 4j)
Distribute/multiply the -3 to everything in the parentheses
-15i + 18j + 2 (-2i + 4j)
Distribute/multiply the 2 to everything in the parentheses
-15i + 18j -4i + 8j
Combine like terms
-19i +26j
Consider the equation 5 + x = n. What must be true about any value of x if n is a negative number?
If n is negative, we have
[tex] 5+x = n<0[/tex]
So, in particular, we have
[tex]5+x<0 \iff x<-5[/tex]
So, x must be smaller than -5
The true statement about the equation [tex]5+x=n[/tex] is that [tex]5+x=n < 0[/tex] and [tex]5+x=x < -5[/tex].
What is inequality?The relation between two expressions that are not equal, employing a sign such as ≠ ‘not equal to’, > ‘greater than’,
If n is negative, we have
[tex]5+x=n < 0[/tex]
So, in particular, we have
[tex]5+x=x < -5[/tex]
So, x must be smaller than -5

the louvre pyramid is a metal and glass structure that serves the main entrance to the louvre Museum in Paris,France. The pyramid has a volume of 8820 cubic meters The base is a square woth sides that are 35 meters long
Answer:
h = 21.6 m
Step-by-step explanation:
*I'm assuming that you need the height. If not, let me know and I'll edit my answer...
The formula for volume of a pyramid is
V = (1/3)Bh where B is the area of the base, and h is the height
We are given V = 8820, and the base is a square with area of 35² = 1225, plug those in and find the height...
8820 = (1/3)(1225)h
26460 = 1225h (multiply both sides by 3 to get rid of the fraction)
26460/1225 = h (divide both sides by 1225 to isolate h)
21.6 = h
Answer:
1946m ²

The perimeter of a square is equal to four times the length of a side. Write the direct v variation equation that represents the situation. Y be the dependent variable and let X the independent variable
Answer: [tex]y=4x[/tex]
Step-by-step explanation:
A direct variation equation has the form:
[tex]y=kx[/tex]
Where k is a constant.
By definition, we know that the perimeter of the square is the sum of the lengths of its sides or, as all the sides are equal, you can multiply the lenght of any side by 4.
Then, knowing that y is the dependent value and x the independent value and the constant k=4, you can write the following direct variation equation that represents the situation.
[tex]y=4x[/tex]
Final answer:
The direct variation equation that represents the perimeter (Y) of a square in relation to its side length (X) is Y = 4X, where the constant of variation is 4.
Explanation:
The question asks us to write a direct variation equation where perimeter of a square is the dependent variable (Y) and the side length is the independent variable (X). For a square, the perimeter (P) is equal to four times the side length (s), hence we can write the direct variation equation as Y = 4X. This equation indicates that the perimeter of a square directly varies with its side length, with the constant of variation being 4.

-1/3(n+15)=-2. what is n? please show work on paper and send it to me asap.
Step-by-step explanation:
Use the distributive formula to solve for n:
-a(b + c) = -ab - ac
So, to solve this you would have to use the distributive property:
-1/3n - 5 = -2
Add 5 to both sides
-1/3n - 5 + 5 = -2 + 5
-1/3n = 3
Now, multiply -3 from both sides
-1/3 * -3 n = 3 * -3
Simplify
n = -9
Hope that helped!!
~A̷l̷i̷s̷h̷e̷a̷♡
Answer:
n= -9
Step-by-step explanation:
-1/3(n+15) = -1/3 * n and -1/3* 15
-1/3*n= -1/3n
-1/3*15= -5
-1/3n -5= -2
Add 5 to both sides
-1/3n = 3
Now divide 3 by -1/3
3/ (-1/3) = -9
n= -9

In this figure, ABC is circumscribed about OQ. find the perimeter of ABC.
Answer options: 66, 58, 54, 62
Answer:
the answer is 66
Step-by-step explanation:
Theorem :If from one external point, two tangents are drawn to a circle then they have equal tangent segments.
Two tangents DB and BE are drawn to a circle from one point i.e.B
So, Using theorem
DB=BE =10 cm
So, Using theorem
CF = CE = 15 cm
So, using theorem
AD =FA = 8 cm
Now AC = FA+CF = 8+15=23 cm
CB =BE+EC = 10+15=25 cm
AB = AD+DB=8+10=18 cm
Perimeter of triangle = Sum of all sides
=AB +CB+AC
= 18 + 25 +23
= 56 cm
Hence the perimeter of ΔACB is 56 cm
On Wednesday, Dia ran 1 1/2 hours at an average speed of 4 miles per hour. How far did she run? (Please show the work ty.)
Final answer:
Dia ran for 1 1/2 hours at a speed of 4 mph. To find the distance, multiply the time (1.5 hours) by the speed (4 mph) to get a total distance of 6 miles.
Explanation:
On Wednesday, Dia ran for 1 1/2 hours at an average speed of 4 miles per hour. To calculate how far Dia ran, we can use the formula for distance, which is d = v × t, where d stands for distance, v stands for velocity (speed in this case), and t stands for time.
To start, we convert the 1 1/2 hours into a decimal to make the multiplication easier. Since 1/2 hour is equivalent to 0.5 hours, Dia ran for a total of 1.5 hours.
Now we calculate the distance using the formula:
Given: t = 1.5 hours, v = 4 mphDistance (d) = v × t = 4 mph × 1.5 hoursDistance (d) = 6 milesTherefore, Dia ran a total distance of 6 miles.
What is the answer to this quation
Answer:
Step-by-step explanation:
g(t)=t^2 - t
f(x) = (1 + x)
g(f(x)) = f(x)^2 - f(x)
g(f(x)) = (x + 1)^2 - x - 1
g(f(0)) = (0 +1)^2 - x - 1
g(f(0)) = 1 - 1 - 1 = -1
================================
f(x) = 1 + x
f(g(t)) = 1 + g(t)
f(g(t)) = 1 + t^2 - t
f(g(0)) = 1 + 0 - 0
f(g(0)) = 1
The answer I'm getting is 0.
Answer:
Step-by-step explanation:g(t)=t^2 - t
f(x) = (1 + x)
g(f(x)) = f(x)^2 - f(x)
g(f(x)) = (x + 1)^2 - x - 1
g(f(0)) = (0 +1)^2 - x - 1
g(f(0)) = 1 - 1 - 1 = -1

ill mark brainliest!What is the total surface area of this rectangular pyramid?
(square ft)
Answer:
S.A. = 225 ft²Step-by-step explanation:
We have a rectangle with dimensions 12 ft × 6 ft in the base of the pyramid and two pairs of triangles with a base of 12 ft and 6 ft and heights of 8 ft and 9.5 ft.
The area of a base:
[tex]A_B=(12)(6)=72\ ft^2[/tex]
The areas of the triangles:
[tex]A_1=\dfrac{(12)(8)}{2}=(6)(8)=48\ ft^2\\\\A_2=\dfrac{(6)(9.5)}{2}=(3)(9.5)=28.5\ ft^2[/tex]
The Surface Area:
[tex]S.A.=A_B+2A_1+2A_2[/tex]
Substitute:
[tex]S.A.=72+2(48)+2(28.5)=72+96+57=225\ ft^2[/tex]
Find the value of X to the nearest tenth.
Answer options: 10.5, 9.9, 10.1, 8.9.
Answer:
9.9
Step-by-step explanation:
Given the right angle triangle, we simply apply Pythagoras theorem to determine the length of the remaining side x;
x^2 = 18^2 - 15^2
x^2 = 99
x = sqrt(99) = 9.9
Answer:
9.9
Step-by-step explanation:
To find the value of x, we use the Pythagorean Theorem.
[tex]a^{2}+b^{2}=c^{2}[/tex]
a = x
b = 15
c = 18
[tex]x^{2}+15^{2}=18^{2}[/tex]
[tex]x^{2} + 225 = 324[/tex]
[tex]x^{2}=342-225[/tex]
[tex]x^{2}=99[/tex]
[tex]\sqrt{x^{2} }=\sqrt{99}[/tex]
[tex]x=9.95[/tex]

if sin(x)=1/2, what is cos(x) and tan(x)? explain your steps in complete sentences
sin(x) = 1/2 when x is 30°, 150°, 210°, or 330° (unit circle).
With those angles, the cos(x) is ±√3/2 and the tan(x) is ±√3/3.
Answer:
[tex]cos(x)=\pm \frac{\sqrt3}{2}[/tex]
[tex]\tan(x)= \pm \frac{1}{\sqrt3}[/tex]
Step-by-step explanation:
We are given the following information in the question:
[tex]\sin(x) = \displaystyle\frac{1}{2}[/tex]
We use the trigonometry identity:
[tex]\sin^2(x) + cos^2(x) =1[/tex]
Putting the value, we get,
[tex]\bigg(\displaystyle\frac{1}{2}\bigg)^2 + \cos^2(x) = 1\\\\\cos^2(x) = \frac{3}{4}\\\\\cos(x)=\pm \frac{\sqrt3}{2}[/tex]
Formula:
[tex]\tan(x) = \displaystyle\frac{sin(x)}{cox(x)}\\\\tan(x) = \frac{\pm \frac{1}{2}}{\frac{\sqrt3}{2}} = \pm \frac{1}{\sqrt3}[/tex]

Find the area of the circle. Leave your answer in terms of pi.
Answer options:
16pi yd2
2pi yd2
4pi yd2
8pi yd2
Answer:
The correct answer is 4pi yd²
Step-by-step explanation:
The area of a circle is calculated using the formula A=πr², where A is area and r is radius of the circle. We obtain the radius of the circle by dividing the length of the diameter by 2, thus, the radius of the circle in the question is 4yd/2=2yd
substituting for the values we get, A= π×(2yd)²
A=4π yd²
ANSWER
[tex]A=4\pi {yd}^{2} [/tex]
EXPLANATION
The area of a circle is calculated using the formula,
[tex]A=\pi \: {r}^{2} [/tex]
The given circle has diameter which is 4 yards.
We divide the diameter into 2, to get the radius.
[tex]r = \frac{4}{2} = 2yd[/tex]
We substitute the radius to obtain,
[tex]A=\pi( {2}^{2} )[/tex]
This gives us,
[tex]A=4\pi {yd}^{2} [/tex]

Answer:
[tex]6x^4[/tex]
Step-by-step explanation:
the expression we have is:
[tex](\sqrt{2x^3})( \sqrt{18x^5} )[/tex]
Because it is a product of two square roots, we can put it together in one:
[tex]\sqrt{(2x^3)(18x^5)}[/tex]
and we carry out the multiplication inside the square root
(to multiply the variable x we sum the exponents 3+5=8)
[tex]\sqrt{2*18x^{3+5}}\\\\=\sqrt{36x^8} \\[/tex]
and now we can take the square root of 36 which is 6.
and to take the square root if [tex]x^8[/tex] we divide the exponent by 2:
[tex]=6x^{8/2}\\=6x^4[/tex]
the simplified product is: [tex]6x^4[/tex]
