Shinji started with angle ∠ABC and constructed ray BE
Answers
Answer:
A and C
Step-by-step explanation:
Statements B) BA ≅ BC and C) AE ≅ DE guarantee that ray BE bisects angle ABC.
Statement B states that BA is congruent to BC. This means that side AB is the same length as side BC. Since the bisector of an angle divides the opposite side into two segments with equal lengths, this guarantees that ray BE bisects angle ABC.
Statement C states that AE is congruent to DE. This means that the segments AE and DE have the same length. Since the bisector of an angle divides the opposite side into two segments with equal lengths, this guarantees that ray BE bisects angle ABC.
The other statements are not sufficient to guarantee that ray BE bisects angle ABC. For example, if BA is congruent to BD, this does not mean that the segments AE and DE have the same length. Similarly, if BD is congruent to DE, this does not mean that side AB is the same length as side BC.
Therefore, the correct answers are B and C.

The points N, O, P and Q all lie on the same line segment, in that order, such
that the ratio of NO: OP: PQ is equal to 5: 2 : 1. If NQ = 24, find NO.
Answers
Answer:
NO= 15
Step-by-step explanation:
let 5x, 2x and x be the ratio.
5x + 2x + x = 24
8x = 24
x= 24/8 = 3
Now,
NO= 5x = 5×3 = 15

Question 15 of 40
For which sample size (n) and sample proportion () can a normal curve be
used to approximate the sampling distribution?
O A. n = 28; = 0.3
O B. n = 28; p = 0.9
O c. n = 32; p = 0.4
O D. n = 32; p = 0.2
Answers
Answer:
Option C: n = 32; p^ = 0.4
Step-by-step explanation:
The normal curve can be used in this case if; np ≥ 10 or n(1 - p) ≥ 10
A) For n = 28 and p = 0.3;
np = 28 × 0.3 = 8.4 < 10
Thus, it can't be used.
B) For n = 28 and p = 0.9;
np = 28 × 0.9 = 25.2 > 10 Ok
n(1 - p) = 28(1 - 0.9) = 2.8 Not Ok
Thus, it can't be used
C) For n = 32 and p = 0.4
np = 32 × 0.4 = 12.8 > 10 Ok
n(1 - p) = 32(1 - 0.4) = 19.2 > 10 Ok
Thus, it can be used
D) For n = 32 and p = 0.2
np = 32 × 0.2 = 6.4 < 10 Not Ok
Thus it can't be used.

The radius of the circle that surround the star is 5 cm. Which measurement is closest to the circumference of the circle?
Answers
Answer:
31.4cm
Step-by-step explanation:
According to the scenario, computation of the given data are s follows,
Radius (r) = 5 cm
So, we can calculate the circumference of circle by using following formula,
Circumference of circle = 2 π r
By putting the value in the formula, we get
Circumference of circle = 2 × π × 5
= 10 ×π
= 10 × 3.14
= 31.4 cm
Hence, circumference of circle is 31.4cm.

Answer:
Y=59 Z=93
Explanation:
To find Z, you have to know the line is equal to 180 degrees. You then subtract 180-87=93 that’s how you get Z. Then with that you know that 34+Y is going to equal 93 because they are across from each other. I forgot what that property is called, but yeah. Then you subtract 93-34=59 there you go hope that helps :)

Write an exponential function in the form y=ab^xy=ab x that goes through points (0,8) and (2,288)
Answers
Answer:
y = 8•6^x
Step-by-step explanation:
Here, we want to write an exponential equation
To fully write this, we need the values of a and b
From the first coordinates given;
8 = a•b^0
a = 8 since b^0 = 1
Furthermore;
288 = 8•b*2
b^2 = 36
b = √36
b = 6
So we have ;
y = 8•6^x

Hi, so in order to graph you need to know what all those numbers mean.
The -1/2x is the slope or the rise/rub
The -3 is the y-intercept
So start by placing the y-intercept (0,-3), then from there place the slope (-1/2), since the slope is negative instead of going up one and two to the left you are going to go down one and two to the right, then place a point and repeat. After repeating 2-3 times you should be able to connect the points in order to make a line. If you have any questions let me know!

Answer:
Variable
Step-by-step explanation:
If you can substitute a unknown variable with another expression that is equal, you can then solve for another variable, and with that equal expression, solve for the first variable.
Using graphing technology:
1) Graph y=x^2, and then experiment with adding different linear terms (for example, x^2 +4x, x^2+20x,x^2- 50x). Record your observations.
2) Graph y=-x^2, and then experiment with adding different linear terms. Record your observations.
Use your observations to help you complete the table without graphing the equations.

x-coordinate of the vertex
y=x^2+6x
y=x^2-10x

y=-x^2-36x
Some quadratic expressions have no linear terms. Find the x-intercepts and the x-coordinate of the vertex of the graph representing each equation. (Note it is possible for the graph to not intersect the x-axis.) If you get stuck, try graphing the equations.

942 mm 3
Step-by-step explanation:
Since 1.2 cm isn't mm we have to convert that, which will be 12. now we do the formula, which is
V=3.14 x r2 x h
and when we plug in the numbers,
V=3.14 x 25 (5x5) x 12
which is 942
