It takes exactly 26 paper clips laid end to end to make 17 7/8 inches. How long is each paper clip? (I really need the explanation)
Answer:
11/16 inch or 0.6875 inch
Step-by-step explanation:
26 * x = 17 7/8
17 7/8 = 143/8
143/8 ÷ 26 = 143/8 x 1/26 = 143/208 = 0.6875
0.6875 in = 11/16 in

In Parallelogram WXYZ, diagonals WY and XZ intersect at A. WA=x2−24 and AY=2x.
What is WY?
Enter your answer in the box.
WY=
units
Answer:
[tex] \displaystyle WY = 24[/tex]
Step-by-step explanation:
refer the attachment
remember that,
the diagonals of Parallelogram bisect each other so WA=AY
thus our equation is
[tex] \displaystyle {x}^{2} - 24 = 2x[/tex]
move left hand side expression to right hand side and change its sign:
[tex] \displaystyle {x}^{2} - 2x - 24 =0[/tex]
rewrite 2x and 4x-6x:
[tex] \displaystyle {x}^{2} + 4x -6x - 24 =0[/tex]
factor out x:
[tex] \displaystyle x ({x}^{} + 4) -6x - 24 =0[/tex]
factor out -6:
[tex] \displaystyle x ({x}^{} + 4) -6(x + 4) =0[/tex]
group:
[tex] \displaystyle ({x}^{} + 4) (x - 6) =0[/tex]
recall that,
When the product of factors equals 0 then at least one factor is 0 so
[tex] \displaystyle \begin{cases} {x}^{} + 4 = 0 \\ x - 6 =0 \end{cases}[/tex]
[tex] \displaystyle \begin{cases} {x}^{} = - 4\\ x =6 \end{cases}[/tex]
since the length cannot be negative negative x isn't available
therefore
[tex] \displaystyle \therefore x = 6[/tex]
since WA and AY are the part of WY we acquire:
[tex] \displaystyle WY = {x}^{2} - 24 + 2x[/tex]
substitute the got value of x:
[tex] \displaystyle WY = {6}^{2} - 24 + 2.6[/tex]
simplify square:
[tex] \displaystyle WY = 36 - 24 + 2.6[/tex]
simplify multiplication:
[tex] \displaystyle WY = 36 - 24 + 12[/tex]
simplify addition:
[tex] \displaystyle WY = 48- 24[/tex]
simplify substraction:
[tex] \displaystyle WY = 24[/tex]
hence,
[tex] \displaystyle WY = 24[/tex]
Diagonals bisect each other
WA=AYx²-24=2xx²-2x=24x²-2x-24=0x²-6x+4x-24=0x(x-6)+4(x-6)=0(x+4)(x-6)=0Take it positive
x=6Now
AY=2(6)=12WY=12(2)=24A highway makes an angle of 6 degrees with the horizontal. This angle is maintained for a horizontal distance of 8 miles
Complete Question
A highway makes an angle of 6 degrees with the horizontal. This angle is maintained for a horizontal distance of 8 miles
To the nearest hundredth of a mile, how high does the highway rise in this
*mile section?
Answer:
[tex]h=0.84miles[/tex]
Step-by-step explanation:
From the question we are told that:
Angle [tex]\theta = 6 \textdegree[/tex]
Horizontal distance traveled [tex]d=8miles[/tex]
Generally the Trigonometric equation for Height is mathematically given by
[tex]Tan \theta=\frac{h}{5}[/tex]

What is the inverse of f(x)=1.5^x+4
Answer:
Step-by-step explanation:
The inverse function of [tex]f(x) = 1.5^x + 4[/tex] is [tex]f^{-1}(x) = \log1.5(x - 4)[/tex]
In other words, the required answer is [tex]f^{-1}(x) = \log1.5(x - 4)[/tex]
To find the inverse of the function[tex]f(x) = 1.5^x + 4[/tex], we need to swap the roles of x and y and solve for y.
Start with the original function:
[tex]y = 1.5^x + 4[/tex]
Swap x and y:
[tex]x = 1.5^y + 4[/tex]
Solve for y:
Subtract 4 from both sides:
[tex]x - 4 = 1.5^y[/tex]
Take the logarithm (base 1.5) of both sides:
[tex]\log1.5(x - 4) = y[/tex]
Rewrite the equation with y as the subject:
y = log1.5(x - 4)
Therefore, the inverse function of [tex]f(x) = 1.5^x + 4[/tex] is [tex]f^{-1}(x) = \log1.5(x - 4)[/tex]
In other words, the required answer is [tex]f^{-1}(x) = \log1.5(x - 4)[/tex]

Step-by-step explanation:
Bob has a coin cup with four $1 tokens and two $5 tokens in it. He also has two $10 tokens and one $25 token in his pocket.
He randomly draws a token froin the cup, and then randomly draws a token from his pocket. What is the probability that he
will draw $30 in tokens?
OB.
. В
We want to find the probability that Bob will randomly draw $30 in tokens. We will find that the probability is P = 1/6 = 0.167
Finding the probability.
The only case where he draws $30 randomly is when:
He takes one $5 token from the coin cupHe takes the $25 token from his pocket.Then we need to find the probabilities for these two events.
For the first one, the probability will be equal to the quotient between the number of $5 tokens and the total number of tokens in the cup. There are 6 tokens in the cup and 2 of these are $5 tokens, then the probability is:
p = 2/6 = 1/3
For the second event the probability is computed in the same way, he has two tokens in his pocket and one of them is a $25 token, then the probability is:
q = 1/2
The joint probability, the probability that both of these events happen at the same time, is given by the product of the individual probabilities, so we get:
P = p*q = (1/3)*(1/2) = 1/6 = 0.167
So the probability that he draws $30 in tokens is P = 1/6 = 0.167.

A tree that is 12 feet tall casts a shadow that is 9 feet long. At the same time a nearby stop sign casts a shadow that is 6 feet long. What is the height, h , of the stop sign?
A. 4.5 ft
B. 7.3 ft
C. 8 ft
D. 9 ft
Answer:
height / shadow = height / shadow until sun moves or earth tilts
12/9 = h / 6
h = 6*12 /9 = (3*2*3*4 ) / (3*3) = 2 * 4 = 8
So C. 8ft

Which of these values for p and a will cause the function f(x)=Pax to be an exponential growth function
The option are missing in the question. The options are :
A. P = 2, a = 1
B. [tex]$P=\frac{1}{2} ; a =\frac{1}{3}$[/tex]
C. [tex]$P=\frac{1}{2} ; a =1$[/tex]
D. P = 2, a = 3
Solution :
The given function is [tex]$f(x)= Pa^x$[/tex]
So for the function to be an exponential growth, a should be a positive number and should be larger than 1. If it less than 1 or a fraction, then it is a decay. If the value of a is negative, then it would be between positive and negative alternately.
When the four option being substituted in the function, we get
A). It is a constant function since [tex]$2(1^x)=2$[/tex]
B). Here, the value of a is a fraction which is less than 1, so it is a decay function. [tex]$f(x)=\frac{1}{2}\left(\frac{1}{3}\right)^x$[/tex]
C). It is a constant function since the value of a is 1.
D). Here a = 3. So substituting, as the value of x increases by 1, the value of the function, f(x) increases by 3 times.
[tex]$f(x)=2(3)^x$[/tex]
Therefore, option (D). represents an exponential function.

b) 8
c) 6
Step-by-step explanation:
a) Each line contains one large square, at least. The smallest additional area is on the Cat line. Apparently, the fewest people preferred cats.
__
b) The smaller symbols appear to represent 1/4, 1/2, and 3/4 of the larger square. On that basis, we can add all of the symbols to discover there are a total of 10 of them:
1 1/4 +1 3/4 +2 1/2 +1 1/2 + 3 = 8 + (1/4 +3/4) +(1/2 +1/2) = 8 +1 +1 = 10
Since 10 symbols represent 80 people, each large square symbol must represent 8 people.
__
c) The number preferring dogs is (1 3/4)(8) = 14. The number preferring giraffes is (2 1/2)(8) = 20. Then 20 -14 = 6 more people preferred giraffes.
