Parallel lines j and k are cut by transvesal t . Which statement is true about ∠2 and ∠6
Answer:
They both equal
Step-by-step explanation:
The statement is true about ∠2 and ∠6 is corresponding angles.
What is line?A line is a straight one-dimensional figure having no thickness and extending infinitely in both directions. A line is made of a set of points which is extended in opposite directions infinitely. It is determined by two points in a two-dimensional plane. The two points which lie on the same line are said to be collinear points.
Given:
Parallel lines j and k are cut by transversal t .
We have to find statement is true about ∠2 and ∠6.
According to given question we have
Parallel lines j and k are cut by transversal t .
So,
∠2 = ∠6 ( corresponding angles)
∠1 = ∠5 ( corresponding angles)
Therefore, the statement is true about ∠2 and ∠6 is corresponding angles.

A cylinder has a diameter of 7 and height of 10.4 . What is its total surface area to two decimal places
Answer:
305.68
Step-by-step explanation:
π = 3.14(aka pi)
d=diameter
h=height
^=exponent
The formula for doing this types of problem is 2π d/2h + 2π(d/2)^2. So all you do is fill in the diameter and height of the variable.
2π 7/2(10.4) + 2π(7/2)^2=305.68

Expand and simplify
(x - 1)(2x + 3)
Answer:
2x^2+x-3
Step-by-step explanation:
Answer:
2x² + x - 3
Step-by-step explanation:
You need to foil the equation.
Foil = (a + b)(c + d) = ac + ad + bc + bd
(x - 1)(2x + 3)
x · 2x = 2x²
x · 3 = 3x
-1 · 2x = -2x
-1 · 3 = -3
Putting them together gets us:
2x² + 3x - 2x - 3
Add like terms to simplify it.
2x² + x - 3

Complete the square x² + 16.0
Answer:
x^2 + 16x + 32
Step-by-step explanation:
I am going to guess this is from factoring.
In which you need to x's multiplied together to get x^2. So you have:
(x+?) (x+?)
to get 16x you need two 8x's in your factoring square. so it would be
(x+8) (x+8)
Now you found out what you were mulitpling together, then you solve. The final part is multiplying 8 by 8, which is 32.

1. x = -7
2. x = -6
3. x = -1
4. y = 4
Step-by-step explanation:
1. Simply subtract equal and opposite values from positive values and do the same on both sides. Divide the final x value by its coefficient to get 1x = -7
2. Do the same as above AFTER distributing the 4(5 - x)
3. Once again, distribute all values then combine like terms like #1
4. This one uses a fraction to distribute, but it is just like dividing the number by 3 instead of multiplying (6/3 instead of 6 * 3)

write an exponential function in the form y=ab^x 0,6 2,96
Answer: y = 20*4^x
Step-by-step explanation:to find the value of the constants a and b, we just need to use the points given in the equation and solve the system of equations:
point (0,20): x = 0 and y = 20:
20 = a*b^0 = a*1 = a
a = 20
point (2,320): x = 2 and y = 320
320 = 20 * b^2
b^2 = 16
|b| = 4
b = 4 or b = -4
So we have two exponencial equations that pass through these points:
y = 20*4^x and y = 20*(-4)^x
As the questions asks for just one equation, we can answer y = 20*4^xIf you have two points, (x1, y1) and (x2, y2), you can define the exponential ... these points by substituting them in the equation y = abx and solving for a and b. ... In this form, the math looks a little complicated, but it looks less so after you ... Taking 1910 as the starting point, this gives the pair of points (0, 1.75) and (100, 6.87). which well turn out to be y=6(4)^x

Answer:
10cm^2
Step-by-step explanation:
The parallel sides of a parallelogram is 2cm apart
Their sum is 10cm
Therefore the area can be calculated as follows
= 2 ×10/2
= 20/2
= 10 cm^2
Hence the area is 10cm^2

HELP Members of a soccer team suspect the coin used for the coin toss at the beginning of their games is unfair. They believe it turns up tails less often than it should if it were fair. The coach of the team decides to flip the coin 100 times and count the number of tails. His trial results in 35 tails. He decides to carry out a significance test. What is the p-value he obtains and the general conclusion that can be made at a 99% significance level?
The p-value is 0.0013. He should reject the null in favor of the alternative.
The p-value is 0.0013. He should fail to reject the null.
The p-value is 0.9987. He should reject the null in favor of the alternative.
The p-value is 0.9987. He should fail to reject the null.
There is not enough information provided to calculate the p-value and make a conclusion.

answer for points what is the last problem answer
Answer:
8. 95
Step-by-step explanation:
The last equation 37 + 58 can be best solved by solving it vertically. Put 37 and 58 side to side vertically to add easier on a piece of paper. The first digit answer is 15, carry the 1 to the second digit and add it with 3 and 5. Your final answer should be 95.
The property that you should use is the Associative Property where you can switch the numbers to put the larger number on top and the smaller number on the bottom. No matter how it is changed, you should get the right answer.

Step-by-step explanation:
last week:
d = 18
d = 18h = 6
this week:
d = 2.5h
i. if she walked for 6 hours this week, h = 6
d = 2.5h
d = 2.5 × 6
d = 15
* this means she walked at slower pace this week as she can only cover 15 miles in 6 hours whereas she can cover 18 miles in 6 hours last week
ii. if she walked for 18 miles this week, d = 18
d = 2.5h
18 = 2.5h
h = 18/ 2.5
h = 7.2
* this means she walked at a slower pace this week as she needs 7.2 hours to cover 18 miles whereas she only need 6 hours last week

Answer:
a) [tex]\mathbf{ f(g(x))=x+2\sqrt{x} +1}[/tex]
b) [tex]\mathbf{f(g(9))=16}[/tex]
Step-by-step explanation:
We are given:
[tex]f(x)=(x-2)^2\\g(x)=\sqrt{x} +3[/tex]
We need to find [tex]a) f(g(x))\\b) f(g(9))[/tex]
a) First finding: [tex]f(g(x))[/tex]
It can be found by putting the value of g(x) into f(x)
We are given:
[tex]f(x)=(x-2)^2\\Put\:x=g(x)\:i.e. \: x= \sqrt{x} +3\\f(g(x))=(\sqrt{x} +3-2)^2\\Now\: solving:\\f(g(x))=(\sqrt{x} +1)^2\\Using\:formula\:\mathbf{(a+b)^2=a^2+2ab+b^2}\\f(g(x))=(\sqrt{x})^2+2(\sqrt{x} )(1)+(1)^2\\ f(g(x))=x+2\sqrt{x} +1[/tex]
SO, we get: [tex]\mathbf{ f(g(x))=x+2\sqrt{x} +1}[/tex]
b) Now finding: [tex]f(g(9))[/tex]
It can be found by putting x=9 in f(g(x))
We have:
[tex]f(g(x))=x+2\sqrt{x} +1\\Put\:x=9\\f(g(9))=9+2\sqrt{9}+1\\We\:know\: \sqrt{9}=3\\ f(g(9))=9+2(3)+1\\f(g(9))=9+6+1\\f(g(9))=16[/tex]
So, we get: [tex]\mathbf{f(g(9))=16}[/tex]

Answer:
a, b, and d
Step-by-step explanation:
you can have the same output, but not the same input
Answer: a, b, d
Step-by-step explanation:
the x values (input values) CANNOT be the same in a set of coordinates; if they do have the same x values, then the are not a function.
both c and e have some of the same x values so they can't pass the vertical line test and therefore are not functions.
