Find the value(s) of A so that XYZW is an isosceles trapezoid. All answers should be fully simplified.
Answers
Answer:
a = 4√5Step-by-step explanation:
Given
Trapezoid XYWZAs given, sides XW and YZ are parallel and XY = WZ
Since it is isosceles, angles X and W are of same size
Therefore:
a² + 15 = 2a² - 652a² - a² = 15 + 65a² = 80a = √80a = 4√5Related Questions

In a survey of 500 people, 31% percent said they were afraid of flying what decimal represents the number of people who said they were afraid of flying?
Answers
Answer:
0.31
Step-by-step explanation:
Given that :
Total number surveyed = 500
Percentage who are afraid of flying = 31%
Decimal which represents number of people who are afraid of flying :
Converting 31% into decimal form:
31 / 100
= 0.31
Hence 0.31 of the people surveyed were afraid of flying

The area of the rectangle is 48 cm².
Show that x satisfies the equation x2+ 7x - 78=0
Answers
Answer:
area a=lxb
48=(x+10)x(x-3)
48=x2-3x+10x-30
0=x2+7x-30-48
0=x2+7x-78
hence it is proved
The requried, we have shown that x satisfies the equation x² + 7x - 78 = 0.
What is the equation?The equation is the relationship between variables and represented as y = ax + b is an example of a polynomial equation.
Here,
The area of the rectangle is given by the formula:
Area = length x width
Substituting the given expressions for length and width, we have:
Area = (x + 10)(x - 3)
We are also told that the area of the rectangle is 48 cm², so we can set up the equation:
(x + 10)(x - 3) = 48
Expanding the left side using the FOIL method:
x² - 3x + 10x - 30 = 48
Simplifying:
x² + 7x - 78 = 0
Therefore, we have shown that x satisfies the equation x² + 7x - 78 = 0.

Answer:
The function has a relative maximum at (-2,4) and a relative minimum at (2,-4).
Step-by-step explanation:
The graph's highest point is at (-2,4) which would be considered the relative maximum of the graph. The graph's lowest point is at (2,-4) which is the relative minimum. Therefore the relative maximum is at (-2,4) and the relative minimum is at (2,-4)

Pocahontas opens a savings account with $640 dollars that earns 3.9% interest per year not compounded. How much money to the nearest penny will Pocahontas have in 8 years
Answers
Given:
Principal value = $640
Rate of interest = 3.9% not compounded
Number of years = 8
To find:
The amount after 8 years.
Solution:
It is given that the interest is not compounded. It means, we need to find simple interest.
Formula for simple interest:
[tex]I=P\times r\times t[/tex]
where, P is principal, r is rate of interest and t is time in years.
Put P=640, r=0.039 and t=8.
[tex]I=640\times 0.039\times 8[/tex]
[tex]I=199.68[/tex]
So, the interest is $199.68.
Now, amount after 8 years is
[tex]A=P+I[/tex]
where, P is principal and I is interest.
[tex]A=640+199.68[/tex]
[tex]A=839.68[/tex]
Therefore, the amount after 8 years is $839.68.
hiii, this geometry please help
Answers
Explanation:
If you just look at it like a straight line then you know it equals 180° but since it’s cut into pieces we have to figure out the others first.
So on the triangle on the bottom it’s 50 and 50 so add those and subtract from 180 to find out what the third angle in the triangle is.
50+50=100
180-100= 80°
Now the angle to the right of the 60° is going to be 80 because they’re corresponding.
So, if the one side of the split line is 80 then the other must be 100°.

A proportional equation is in the form:
[tex]\displaystyle y=kx[/tex]
Where y is the dependent variable, x is the independent variable, and k is the constant of proportionality.
An important aspect of a proportional equation is that it passes through the origin. That is, it has no y-intercept (or a constant value).
From our choices, the only choices that don’t have y-intercepts are C and D.
However, D is not a linear function.
Therefore, our answer is C.
And our constant of proportionality is 1/2.

Step-by-step explanation:
The complete lewis structure for NOF covalent compound is rewritten as: O=N-F
What type of bond is in NOF (Nitrosyl fluoride)?In a molecule of NOF, Oxygen is double bonded with Nitrogen. Nitrogen molecule of NOF is single bonded with flourine.
Rest of the valence electrons are not bonded.
Nitrogen's atomic number: 7, valence electron's count = 5Oxygen's atomic number: 8, valence electron's count = 6Florine's atomic number: 9, valence electron's count = 7Thus, with the above said description we will get:
