In the figure, TU is tangent to the circle at point U. Use the figure to answer the questions.
(a) Describe the relationship among the lengths of the segments formed by the secant, RT, and the tangent segment, TU. You may use words and/or an equation.
(b) Suppose RT = 9 in. and ST = 4 in. Is it possible to find the length of TU? If so, show how to find the length. If not, explain why not.
Answers
or RT*ST=TU^2
(b) 9*4= TU2
36=TU^2
[tex] \sqrt{36}[/tex]
6=TU^2
Both the parts of this question require the use of the "Intersecting Secant-Tangent Theorem".
Part A
The definition of the Intersecting Secant-Tangent Theorem is:
"If a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment."
This, when applied to our case becomes, "The length of the secant RT, times its external segment, ST, equals the square of the tangent segment TU".
Mathematically, it can be written as:
[tex] RT\times ST=(TU)^2 [/tex]
Part B
It is given that RT = 9 in. and ST = 4 in. Thus, it is definitely possible to find the value of the length TU and it can be found using the Intersecting Secant-Tangent Theorem as:
[tex] RT\times ST=(TU)^2 [/tex]
Thus, [tex] (TU)^2=9\times 4=36 [/tex]
[tex] \therefore TU=\sqrt{36}=6 [/tex]
Thus the length of TU=6 inches
A rectangular deck
is 12 ft by 14 ft. When the length and width are increased by the same amount very becomes 280 squares ft. By how much were the dimensions increased ?
Answers
The other response seems more complex so probably ignore mine. I probably misinterpreted the question.
Original width: 12 ft. New width x + 12.
New area:
[tex] A = LW [/tex] or [tex] LW = A [/tex]
[tex] (x + 14)(x + 12) = 280 [/tex]
[tex] x^2 + 14x + 12x + 168 = 280 [/tex]
[tex] x^2 + 26x - 112 = 0 [/tex]
[tex] x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a} [/tex]
[tex] x = \dfrac{-26 \pm \sqrt{26^2 - 4(1)(-112)}}{2(1)} [/tex]
[tex] x = \dfrac{-26 \pm \sqrt{676 + 448}}{2} [/tex]
[tex] x = \dfrac{-26 \pm \sqrt{1124}}{2} [/tex]
[tex] x = \dfrac{-26 \pm 2\sqrt{281}}{2} [/tex]
[tex] x = -13 \pm \sqrt{281} [/tex]
[tex] x \approx -29.76 [/tex] or [tex] x \approx 3.76 [/tex]
We discard the negative answer.
Answer:

You need to have a password with 4 letters followed by 2 even digits between 0 and 9, inclusive. if the characters and digits cannot be used more than once, how many choices do you have for your password?
Answers
The total number of possible passwords, considering the conditions that no letters or digits can be reused, and only even digits 0-9 can be used, would be 7,893,600.
Explanation:This is a question of combinations and permutations. Firstly, consider the four letters. There are 26 letters in the English alphabet. Since you have four letters and none of them can be the same, the number of possibilities is 26 * 25 * 24 * 23. Next, consider the two numbers. Since we can only choose even numbers between 0 and 9 (which gives us 5 possible selections), and they cannot be the same, the number of possibilities is 5 * 4. Therefore, to find the total number of possible passwords, you multiply the possibilities for letters and numbers together. So, the number of
possible passwords would be 26 * 25 * 24 * 23 * 5 * 4, which equals to 7,893,600.

Answers
Answer:
B.[tex]F(x)=-\mid{x-1}\mid[/tex]
Step-by-step explanation:
We are given that a function
[tex]f(x)=\mid x\mid[/tex]
We have to find absolute value of function when parent function reflected over the x- axis and translated 1 unit to the right.
The transformation rule when the point (x,y) is reflected over x- axis is given by
[tex](x,y)\rightarrow (x,-y)[/tex]
Apply the reflection on function over x- axis then, we get
[tex]g(x)=-\mid x\mid[/tex]
Transformation rule when the point (x,y) is shifted a units towards right is given by
[tex](x,y)\rightarrow (x-a,y)[/tex]
When the graph is translated 1 units towards right then , obtained function is given by

20 POINTS! What is the distance between the points (2, 3) and (5, -4)?
Answers
The distance, d, between points [tex] (x_1, y_1) [/tex]
and [tex] (x_2, y_2) [/tex] is given by the distance formula below.
[tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
Now we can apply the formula to your points.
Let Point 1 be (2, 3) and Point 2 be (5, -4).
Then you have
[tex] x_1 = 2~~~~y_1 = 3~~~~x_2 = 5~~~~y_2 = -4 [/tex]
[tex] d = \sqrt{(5 - 2)^2 + (-4 - 3)^2} [/tex]
[tex] d = \sqrt{(3)^2 + (-7)^2} [/tex]
[tex] d = \sqrt{9 + 49} [/tex]

A street promotion worker gets paid $0.10 for each flyer he hands out. His goal is to make $15 an hour. How many flyers must he hand out each hour?
A. 45
B. 1500
C. 150
D. 15
Answers
The street promotion worker must hand out 150 flyers each hour to make $15.
Explanation:To determine how many flyers the street promotion worker must hand out each hour to make $15, we need to use the equation:
Number of flyers × Payment per flyer = Total payment
Since the worker wants to make $15 an hour, the equation becomes:
Number of flyers × $0.10 = $15
To solve for the number of flyers, we divide both sides of the equation by $0.10:
Number of flyers = $15 ÷ $0.10
Number of flyers = 150
Therefore, the street promotion worker must hand out 150 flyers each hour to make $15.

Jade buys a blouse and a skirt for 34 of their original price. Jade pays a total of $31.50 for the two items. If the original price of the blouse is $18, what is the original price of the skirt? Enter your answer in the box.
Answers
This can be found by first calculating what the total cost of the items was originally. Since you spent $31.50 on items at 34% of their original price, the total cost can be found by dividing the new total by the percentage.
$31.50/.34 = $92.65.
Now we need to find the original price of the blouse. We repeat the same action with the $18 and the percentage.
$18/.34 = $52.94.
Now we can subtract the original cost of the blouse from the original cost of both items.
$92.65-$52.94 = $31.71.
Answer:
The original price of the skirt is $24
Step-by-step explanation:
The question must be 3/4 of their original price. So, I will solve this using 3/4 as 34 is unclear and does not suit the question.
Lets assume that the price of the blouse be = x
Lets say the price of the skirt is = y
Now, given is that 3/4 of the price together for both items is $31.5 0
This means,
[tex]\frac{3}{4}(x+y)=31.50[/tex] ..... (1)
The original price of the blouse is $18 so, x= 18 .............(2)
Putting x=18 in equation (1)
[tex]\frac{3}{4}(18+y)=31.50[/tex]
[tex]3(18+y)=31.50*4[/tex]
[tex]3y+54=126[/tex]
[tex]3y=72[/tex]
y=24
Hence, the original price of the skirt is = $24.
Check:
Original price of both items = [tex]18+24=42[/tex]
And 3/4 of 42 is [tex]\frac{3}{4}*42= 31.50[/tex]
So, the correct answer is $24.
