Geometry: Find the value of x.
X = [?]°
Answer:
x = 25°
Step-by-step explanation:
The secant- secant angle DGB is half the difference of the intercepted arcs, that is
[tex]\frac{1}{2}[/tex] ( BD - FE) = 55
[tex]\frac{1}{2}[/tex](135 - x) = 55 ( multiply both sides by 2 )
135 - x = 110 ( subtract 135 from both sides )
- x = -25 ( multiply both sides by - 1 )
x = 25°

) A basketball court is 94 feet by 50 feet. Eight fans can
fit next to each other in a 3 ft. by 3 ft. area. How
many kids would you estimate can fit side by side
over the entire floor?
Answer:
4178kidsStep-by-step explanation:
Area of the basket ball court = Length * Breadth (since it is rectangular in nature)
Area of the basket ball court = 94 feet * 50 feet
Area of the basket ball court = 4700ft²
Area of the space covered by 8 kids = 3ft * 3ft = 9ft²
To know the number of kids that would fit the entire floor, we will use the expression;
Number of kids in the floor = 8*Area of the basket ball court /Area of the space covered by 8 kids = 8*4700/9
= 8*4700/9
= 8*522.22
≈ 4,178 kids
Hence approximately 4,178 kids can fit side by side over the entire floor

Johanna rode her bike 7 miles to a lake . She rode 3/4 of distance to the lake before lunch. How many miles did johanna ride before lunch?
Answer:
5.25 miles
Step-by-step explanation:
Total distance = 7 miles
Distance she rode before lunch = 3/4 of the total distance
=> 3/4 of 7
=> 21/4
=> 5.25 miles
So, she drove 5.25 miles before lunch.
In a multiplicative model, if the seasonal factor is 1.15 for a particular season, then we expect that the time series in that season would be (other things being equal
Answer:
15% above the trend.
Step-by-step explanation:
A time series represented by Y comprises of dataset observed over a particular period of time. Time series is handy in determining the future of a particular business.
In a multiplicative model, if the seasonal factor is 1.15 for a particular season, then we expect that the time series in that season would be
Y = T × C × S × 1
where;
Seasonal S = 1.15
As such Y would increase by 15% above the trend if all other things are being equal.
Y=4x-3; A(5,17) Use substitution to determine whether the point is on the line.
Answer:
the point is on the line
Step-by-step explanation:
The ordered pair gives the values of (x, y). Put those values in the equation and see if it is true:
y = 4x -3
17 = 4(5) -3 = 20 -3 . . . . . . for (x, y) = (5, 17)
17 = 17 . . . . true, the point is on the line

what is the probability that the card drawn from a stack of 52 cards is a face card or a black card?
Answer: 8/13
Step-by-step explanation:
There are 52 cards in a deck.
26 cards are black --> P(Black) = 26/52
Face cards are J, Q, K. There are 12 face cards --> P(Face) = 12/52
6 Face cards are black --> P(both) = 6/52
Face card or Black card - both Face card & Black
[tex]\dfrac{26}{52}[/tex] + [tex]\dfrac{12}{52}[/tex] - [tex]\dfrac{6}{52}[/tex] [tex]=\dfrac{32}{52}[/tex]
[tex]\dfrac{32}{52}\div \dfrac{4}{4}=\dfrac{8}{13}[/tex]
Which of the following is an odd function?
f(x) = x3 + 5x2 + x
f (x) = StartRoot x EndRoot
f(x) = x2 + x
f(x) = –x
Answer: [tex]f(x)=-x[/tex]
Step-by-step explanation:
When f(-x)= -f(x), then it is known as an odd function.
i) [tex]f(x) = x^3 + 5x^2 + x[/tex]
Then, [tex]f(-x)=(-x)^3+5(-x)^2+(-x)=-x^3+5x^2-x\neq -x^3-5x^2-x[/tex]
i.e. [tex]f(-x)\neq-f(x)[/tex]
ii) [tex]f(x)=\sqrt{x}[/tex]
[tex]f(-x)=\sqrt{-x}\neq-\sqrt{x}[/tex]
i.e. [tex]f(-x)\neq-f(x)[/tex]
iii) [tex]f(x)=x^2+x[/tex]
[tex]f(-x)=(-x)^2+(-x)=x^2-x\neq-x^2-x[/tex]
i.e. [tex]f(-x)\neq-f(x)[/tex]
iv) [tex]f(x)=-x[/tex]
[tex]f(-x)=-(-x)=x[/tex]
[tex]-f(x)=-(-x)=x[/tex]
i.e. [tex]f(-x)=-f(x)[/tex]
Hence, f(x) is an odd function.

Perform the calculations and determine the absolute and percent relative uncertainty. Express each answer with the correct number of significant figures. To avoid rounding errors, do not round your answers until the very end of your calculations. [8.47(±0.06)]1/3=[8.47(±0.06)]1/3= absolute uncertainty: ±± percent relative uncertainty: ±± %% log[6.56(±0.05)]=log[6.56(±0.05)]= absolute uncertainty: ±± percent relative uncertainty ±± %%
Answer: (a). 0.2% (b). 0.4%
Step-by-step explanation:
This is quite straightforward, so let us follow this carefully.
(a) let us consider the expression that was given in the question;
(8.47 + 0.06)1/3 from the binomial expression,
⇒ (x + ∆x)n = xn + nxn-1∆x
So using the stated formula above
(8.47 + 0.06)1/3 = (8.47)1/3+ 1/3(8.47)1-(1/3) (0.06) = 2.038 + 1/3(8.47)(2/3) (0.06)
= 2.038 + 0.005
This gives us the algebric value as x = 2.038
Also, the uncertainity is ∆x = 0.005
Let us calculate the percentage of relative uncertainity;
Relative uncertainity percent is given thus;
⇒ (∆x / x) * 100
= (0.005 / 2.038) * 100 = 0.2%
We have that the relative uncertainity percent is 0.2%
(b). Also we will consider the expression;
log(6.56 + 0.05)
Let us apply the binomial expression to this;
log(6.56 + 0.05) = log(6.56) + ((0.05)2 / 6.56) = 0.817 + 0.003
This makes the algebric value of x = 0.817
and the uncertainity is ∆x = 0.003
Therefore the Relative uncertainity percent is = (∆x / x) * 100
= (0.003 / 0.817) * 100 = 0.4%
We have the relative uncertainity percent as 0.4%
cheers I hope this helped !!

If a=8 and b=5 and x=4 and y=6m -2 what is the value of m ?
Answer:
m = 2
Step-by-step explanation:
Given:
x = 4
y = 6m - 2
a = 8
b = 5
Required:
Value of m
SOLUTION:
x and y are segments of a chord divided when it intersects another chord that also has segments a and b.
According to the Intersecting chords theorem, [tex] a*b = x*y [/tex]
Thus:
[tex] 8*5 = 4*(6m - 2) [/tex]
Solve for m
[tex] 40 = 24m - 8 [/tex]
[tex] 40 + 8 = 24m - 8 + 8 [/tex]
[tex] 48 = 24m [/tex]
[tex] \frac{48}{24} = \frac{24m}{24} [/tex]
[tex] 2 = m [/tex]
The value of m = 2
