Answer:
2[tex]\sqrt{3}[/tex] or ~3.464
Step-by-step explanation:
We see that the triangle ABC has an angle of 90° and 45°, so 90+45 is 135, and 180-135 is 45° which is a special triangle. The hypotenuse is k[tex]\sqrt{2}[/tex] and we know that k is 6 so the other side lengths are 6 since they are just k. Now the triangle CBD hares a side so it is 6 and the angles are 60° and 90° so the last angle is 30° which is another special triangle. Since the side length is 6 and it equals [tex]\frac{\sqrt{3} }{2}[/tex]k. We divide 6 by [tex]\frac{\sqrt{3} }{2}[/tex] and we get 4[tex]\sqrt{3}[/tex] which is the value of k or the hypotenuse. To find x, we multiply k by 1/2 or divide it by 2. Dividing 4[tex]\sqrt{3}[/tex] by 2 gives us 2[tex]\sqrt{3}[/tex] which is x. If the question wants the exact number, then it is 3.464, otherwise, just put 2[tex]\sqrt{3}[/tex]. Hope this helps! (I'm not a bot btw)

Step-by-step explanation:
there are 5 possible events (01234)- there are 3 favorable outcomes (123)
so that's 3 out of 5 or 3/5 or 60%
The estimated probability of a success is 3/5 or 60%.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

Triangle ABC underwent a sequence of transformations to give triangle A′B′C′. Which transformations could not have taken place? A. a reflection across the line y = x followed by a reflection across the line y = -x B. a reflection across the x-axis followed by a reflection across the y-axis C. a rotation 180° clockwise about the origin followed by a reflection across the line y = x D. a reflection across the y-axis followed by a reflection across the x-axis
Answers
Answer:
C. a rotation 180° clockwise about the origin followed by a reflection across the line y = x
Step-by-step explanation:
Let us assume that the coordinate of A in triangle ABC is A(x, y)
A) If there is a reflection across line y = x, the new coordinate is at A'(y, x).
If a reflection across the line y = -x is then followed, the new coordinate is at A"(-x, -y)
B) If there is a reflection across line x axis, the new coordinate is at A'(x, -y).
If a reflection across the line y axis is then done, the new coordinate is at
A"(-x, -y)
C) If there is a rotation 180° clockwise about the origin, the new coordinate is at A'(-x, -y).
If a reflection across the line y = x is then followed, the new coordinate is at A"(-y, -x)
D) B) If there is a reflection across line y axis, the new coordinate is at A'(-x, y).
If a reflection across the line x axis is then done, the new coordinate is at
A"(-x, -y)
Since only option C has a different result from the remaining options, hence option C would not five triangle A'B'C'

A karate school offers a package of 12 group lessons and 2 private lessons for $110. It also offers a package of 10 group lessons and 3 private lessons for $125. Write and solve a system of equations to find the cost of a single group lesson and a single private lesson.
Answers
Answer: The cost of a single group lesson is $5 and a single private lesson is $25
Step-by-step explanation:
Let the cost of a single group lesson be y.
Let the cost of a single private lesson be z.
A karate school offers a package of 12 group lessons and 2 private lessons for $110. This can be written as:
12y + 2z = 110 ..... equation i
It also offers a package of 10 group lessons and 3 private lessons for $125. This can be written as:
10y + 3z = 125 ...... equation ii
Combining equation i and ii
12y + 2z = 110 ..... equation i
10y + 3z = 125 ...... equation ii
12y + 2z = 110 × (3)
10y + 3z = 125 × (2)
36y + 6z = 330 ....... equation iii
20y + 6z = 250 ...... equation iv
Subtract equation iv from iii
16y = 80
y = 80/16
y = 5
From equation ii
10y + 3z = 125
10(5) + 3z = 125
50 + 3z = 125
3z = 125 - 50
3z = 75
z = 75/3
z = 25
The cost of a single group lesson is $5 and a single private lesson is $25
A group lesson costs = $5.
A private lesson costs = $25.
Let a group lesson costs = $x
A private lesson costs = $y.
According to the question:
12x + 2y = 110
10x + 3y = 125
Solving them we get x = 5, y = 25

y = 4x + 10
solution:
so first you have to find the slope, there is an equation for it. it is y2 - y1/ x2 - x1 or just y1 - y2/ x1 - x2 . so input the easiest points. id say f(0) and f(1)
so it will look like
2 - 6/0 - 1
-4/-1
4
so you can now write the equation as
y = 4x + b
now you have to find the y-intercept so input a point. i dont think you should input a point you used to find the slope because you could have made a mistake calculating so lets input f(2)
sooo
18 = 4(2) + b
18 = 8 + b
b = 10
so the function for the second one is y = 4x + 10

what is x
Answers
Answer:
x = 4
Step-by-step explanation:
it's important to keep in mind that you can do anything to an equation as long as you do it to both sides, and it will still be equal.
2x + 5 = 13
subtract 5 from both sides of the equation
2x + 5 -5 = 13 - 5
2x = 13 -5
2x = 8
divide both sides of the equation by 2
2x/2 = 8/2
x = 4
The value of x for the equation 2x + 5 = 13 is x = 4.
Given that:
There is an equation in x which is given as,
2x + 5 = 13
It is required to find the value of x.
That is, solve the equation.
It is required to get the equation in such a way that x is on one side and a constant on the other side.
2x + 5 = 13
Subtract both sides by 5.
2x = 8
Divide both sides by 2.
x = 4
Hence the value of x is 4.

If the height of an object at time t can be represented by
h(t) = -16t2 + 38t + 9, find h(7).
Answers
Answer:
-509
Step-by-step explanation:
h(t) = -16t² + 38t + 9
h(7) = - 16(49) + 38(7) + 9
h(7) = -784 + 266 + 9
h(7) = -509
Solution:
It should be noted:
Given equation: h(t) = -16t² + 38t + 9To find h(7), let's find "t" by comparing h(7) and h(t).
Compare h(7) and h(t):
h(7) = h(t)=> h(7)/h = h(t)/h=> 7 = tNow, find h(7) by substituting the value of t into the equation.
Substitute the value of t into the equation:
h(t) = -16t² + 38t + 9=> h(t) = (-16)(t²) + (38)(t) + 9=> h(7) = (-16)(7²) + (38)(7) + 9=> h(7) = -784 + 266 + 9=> h(7) = -509Thus, h(7) is -509.
