A trapezoid has an area of 150 square meters. If the bases are 14 meters and 16 meters, what us the height of the trapezoid?
Answers
[tex]a = \frac{1}{2} (b1 + b2) \times h[/tex]
In this formula a represents the area and b1 and b2 each represent a base of the trapezoid.
So, we have got the following information
[tex]a = 150[/tex]
[tex]b1 = 14[/tex]
[tex]b2 = 16[/tex]
Filling in the formula gives us:
[tex]150 = \frac{{1} }{2} \times (14 + 16) \times h[/tex]
[tex]150 = \frac{1}{2} \times 30 \times h[/tex]
[tex]150 = 15 \times h[/tex]
Finally we have to divide both sides by 15.
[tex]h = 150 \div 15 = 10[/tex]
Therefore, the height of the trapezoid is 10 meters.

Which table represents the probability distribution for the variable X?
Answers

What is the measure of ∠EGF?
What is the measure of ∠CGF?
Answers
= 1/2(130)
= 65
the measure of ∠CGF = 180 - 65
= 115
This is an isosceles triangle, which means its base angles are congruent. Interior angles of triangle add to equal 180 degrees, so you can make an equation to solve for the measure of the base angles. I'll call the base angles x.
180 = 50 + 2x
130 = 2x
65 = x
That gives you m∠EGF and m∠FGE (65°).
To find m∠CGF, you must know that it and ∠EGF are supplementary (they add to equal 180 degrees). Make another equation setting them to equal 180 using m∠EGF (65°):
180 = 65 + x
115 = x
Answer:
m∠EGF = 65°
m∠CGF = 115°

In parallelogram DEFG, DH = x + 3, HF = 3y, GH = 3x – 3, and HE = 5y + 4. Find the values of x and y.
x = 5, y = 12
x = 5, y = 9
x = 4, y = 9
x = 9, y = 4
Answers
DH = HF
x + 3 = 3y
GH = HE
3x - 3 = 5y + 4
We then have the following system of equations:
x-3y = -3
3x-5y = 7
Resolving the system graphically we obtain the following values:
x = 9
y = 4
Note: see attached image.
Answer:
The values of x and y are:
x = 9, y = 4
Final answer:
In parallelogram DEFG, DH = x + 3, HF = 3y, GH = 3x – 3, and HE = 5y + 4. Solving the equations yields x = 9, y = 4.
Explanation:
To find the values of x and y in parallelogram DEFG, we'll use the properties of parallelograms. In a parallelogram, opposite sides are equal in length.
Given that DH = x + 3 and HF = 3y, and that DH is opposite to HF, we have:
x + 3 = 3y ...(1)
Similarly, given GH = 3x - 3 and HE = 5y + 4, and that GH is opposite to HE, we have:
3x - 3 = 5y + 4 ...(2)
Now, we have a system of two equations (1) and (2) to solve for x and y.
From equation (1):
x = 3y - 3 ...(3)
Substitute equation (3) into equation (2):
3(3y - 3) - 3 = 5y + 4
9y - 9 - 3 = 5y + 4
9y - 12 = 5y + 4
4y = 16
y = 4
Now, substitute the value of y into equation (3):
x = 3(4) - 3
x = 12 - 3
x = 9
So, the values of x and y are x = 9 and y = 4. Thus, the correct answer is x = 9, y = 4.

You could also input the x values and see which equation produces the y values in the chart.
On thing to notice is the we have negative output values, there we need to pick either B or D, so the values go beneath the x-axis.
Answer:
option D.
Step-by-step explanation:
Data given in the table is
x 2 3 4
f(x) -3 0 12
Now we will plug in the values of x in the given functions to find the correct exponential function.
For x =2
A). f(x) = 4(4)[tex]^{(x-1)}[/tex] + 4
f(2) = 4(4)[tex]^{2-1}[/tex] + 4 = 4 × 4 + 4 = 20
B). f(x) = 4(4)[tex]^{(2-1)}[/tex] - 4
f(2) = 4(4)[tex]^{2-1}[/tex] - 4 = (4)(4) - 4 = 16 - 4 = 12
C). f(x) = 1/4(4)[tex]^{x-1}[/tex] +4
1/4(4)[tex]^{2-1}[/tex] + 4 = [tex]\frac{1}{4}[/tex] × 4 + 4
= 1 + 4 = 5
D). f(x) = [tex]\frac{1}{4}(4)^{x-1}-4[/tex]
f(2) = [tex]\frac{1}{4} (4)^{2-1}-4=\frac{1}{4}(4)-4[/tex]
= 1 - 4 = -3
We find option D in which f(2) = (-3). so the answer would be option D.

Answers
Equilateral Triangular Prism
Each side of the triangular face has a length of 196cm
The tent is 250cm long
I have attached an image of the tent. Since the height of the tent is also the height of the triangle, I will solve for the height of the triangle using Pythagorean theorem.
I divided the equilateral triangle into 2 right triangle. The height then becomes the long leg of the triangle. The hypotenuse is 196cm and the short leg is 98cm, half of one side of the triangle.
a² + b² = c²
a² = c² - b²
a² = (196cm)² - (98cm)²
a² = 38,416cm² - 9,604cm²
a² = 28,812cm²
a = √28,812cm²
a = 169.74cm
The height of the tent is 169.74 centimeters.

A store owner paid $15 for a book she marked up the price of the the book by 40% to determine its selling price part A what is the selling price of the book? Part B a customer buys a different book that has an original selling price of $38 the book is discounted 25% the costumer must pay 6% sales tax on the discounted price of the book .what is the total amount the customer must pay for the discounted book
Answers
40% = 0.4
15*0.4 = 6
15 + 6 = 21
The marked up price is $21
B:
To find the discounted price:
25% = 0.25
38*0.25 = 9.5
38 - 9.50 = 28.50
To find the tax and price after tax:
6% = 0.06
28.50*0.06 = 1.71
So tax is $1.71
28.50 + 1.71 = 30.21
Price after tax is $30.21

we have been asked to find the Least Common multiple of the given polynomial x² + x – 12 and x² + 2x – 15.
To find the least common multiple. Lets first find the factors.
[tex] x^2+x-12=x^2+4x-3x-12\\
\\
x^2+x-12=x(x+4)-3(x+4)\\
\\
x^2+x-12=(x+4)(x-3)\\ [/tex]
[tex] x^2+2x-15=x^2+5x-3x-15\\
\\
x^2+2x-15=x(x+5)-3(x+5)\\
\\
x^2+2x-15=(x+5)(x-3)\\ [/tex]
Hence the LCM of the given set of Polynomials is (x+4)(x-3)(x+5).
The LCM is (x+4)*(x-3)*(x+5)

If GH = 3 and HJ = 5, then G ___ J.
Choose the relationship symbol that would make a true statement.
Answers
Step-by-step explanation:
The given equation is as follows.
GH = 3 and HJ = 5
Therefore, simplify for H from both the equations as follows.
H = [tex]\frac{3}{G}[/tex] .......... (1)
and, H = [tex]\frac{5}{J}[/tex] .......... (2)
Equating both equation s(1) and (2), we get the following.
[tex]\frac{3}{G}[/tex] = [tex]\frac{5}{J}[/tex]
G = [tex]\frac{3J}{5}[/tex]
or, G = 0.6J
This means that J will be 0.6 times greater than G.
Thus, we can conclude that G < J.

Find the inverse of the following function. f(x) 8√ x for x > 0
Answers
The inverse of the function f(x) = 8√x for x > 0 is g(x) = x^2/64.
To find the inverse of the function f(x) = 8√x for x > 0, we need to interchange the roles of x and y and solve for y.
Let's start by rewriting the function using y instead of f(x):
y = 8√x
Next, we'll swap x and y:
x = 8√y
To isolate y, we can square both sides:
[tex]x^2 = (8\sqrt y)^2\\\\x^2 = 64y[/tex]
Now, divide both sides by 64:
[tex]x^2/64 = y[/tex]
Simplifying further:
[tex]y = x^2/64[/tex]
Therefore, the inverse of the function f(x) = 8√x for x > 0 is given by [tex]g(x) = x^2/64.[/tex]

Instructions:Select the correct answer from each drop-down menu. The sum of the squares of two consecutive positive even numbers is 340. Find the numbers. The consecutive even numbers are
Answers
[tex] x^{2} + (x + 2)^{2} = 340[/tex]
If we expand the second term:
[tex] x^{2} + x^{2} + 4x + 4 = 340[/tex]
Combine like terms:
[tex]2 x^{2} + 4x + 4 = 340[/tex]
You can reduce this by dividing both sides of the equation by two:
[tex] x^{2} + 2x + 2 = 170[/tex]
And we transpose 170 to get a standard quadratic form that the right side will be zero:
[tex] x^{2} + 2x - 168 = 0[/tex]
Then factor the left side:
[tex](x +14)(x-12) = 0[/tex]
Find out the values of x that makes each factor = 0
x + 14 = 0
x = -14
We can eliminate the negative symbol because the problem is asking for positive even integers.
and;
x - 12 = 0
x = 12
Now we can say that the first positive integer is 12 and the second one is 14
the sum of the squares of these 2 numbers are 340
x² + (x+2)² = 340
x² + x² + 4x + 4 = 340
2x² + 4x - 336 = 0
we are left with a quadratic equation
coefficient of x is 2 therefore divide each number by 2
x² + 2x - 168 = 0
to solve the quadratic equation , the 2 factors whose product is 168x² and sum is 2x is -12x and 14x
x² + 14x -12x -168 = 0
x (x + 14) - 12(x + 14)=0
(x+14)(x-12) = 0
we have 2 possible values for x
x + 14 = 0 x-12 = 0
x = -14 x = 12
from the 2 answers the correct answer is x = 12 as it should be a positive integer
one integer is 12 and consecutive even integer is 14
to check the product of the squared numbers
= 14² + 12²
= 196 + 144
= 340
