Jane drew a point A located at (-2,-3) and point C located at (8,-3). What is the x-coordinate of point B that bisects? AC
Answer:
x-coordinates of point B = 3
Step-by-step explanation:
If the extreme ends of a segment are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex], coordinates of the midpoint of the given segment will be = [tex](\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]
Coordinates of the extreme ends of segment AC are A(-2, -3) and C(8, -3).
Since B is a point that bisects the segment AC, coordinates of point B will be,
= [tex](\frac{-2+8}{2},\frac{-3-3}{2})[/tex]
= (3, -3)
Therefore, x-coordinates of the point B will be = 3

6 ( n + 5 ) = 66
Answer:
n=6
Step-by-step explanation:
6 ( n + 5 ) = 66
Divide each side by 6
6/6 ( n + 5 ) = 66/6
n+5 = 11
Subtract 5 from each side
n+5-5 = 11-5
n = 6
Answer:
n=6
Step-by-step explanation:
We are given the equation
6(n+5)=66
We must solve for the variable, n. Therefore, we have to isolate n on one side of the equation.
6 is being multiplied by (n+5). The inverse of multiplication is division. Divide both sides of the equation by 6.
6(n+5)/6=66/6
(n+5) = 66/6
n+5 = 11
5 is being added to n. The inverse of addition is subtraction. Subtract 5 from both sides of the equation.
n+5-5=11-5
n=11-5
n=6
Let's check our solution. Plug 6 in for n and solve.
6(n+5)=66
6(6+5)=66
6(11)=66
66=66
The statement above is true, so we know our solution is correct.
The solution to the equation 6(n+5)=66 is n=6
The back of Dante's property is a creek. Dante would like to enclose a rectangular area, using the creek as one side and fencing for the other three sides, to create a pasture. If there is 720720 feet of fencing available, what is the maximum possible area of the pasture
The correct value is 720 ft of fencing.
Answer:
Max Area = 64800 sq.ft
Step-by-step explanation:
A square will always give us the maximum area.
Thus, one side would be;
720/4 = 180 feet
So, we want a square 180 ft by 180 ft
however, from the question, we are to use the creek as one side. So, we'll take the 180 ft that we don't need because of the creek and then add it to the opposite side to get 180 + 180 = 360 ft.
Thus,we now have a rectangle with dimensions: 180 ft by 360 ft
Area is given by;
area = length × width
Maximum Area = 180 × 360
Max Area = 64800 sq.ft

Let f(x) = x^2 + 4 and g(x) = 7x + 13. Find g(f(3)).
Answer:
104
Step-by-step explanation:
f(x) = x^2 + 4
g(x) = 7x + 13.
Find g(f(3))
Find f(3) = 3^2+4 = 9+4 = 13
Then find g(13) = 7*13 + 13 = 91+13 = 104
Answer:
91x+169
g(f(3))
(7x+13)(3^2+4)
(7x+13)(9+4)
(7x+13)(13)
therefore..91x+169
How many solutions does the system have?
y= -3x + 9
3y = -9x + 9
Choose 1 answer
A. Exactly one solution
B. No solutions
C. Infinitely many solutions
Answer:
B. No solutions
Step-by-step explanation:
y= -3x + 9
3y = -9x + 9
Rewrite the first equation below. Then, divide both sides of the second equation by 3 and write it below the first equation.
y = -3x + 9
y = -3x + 3
Now look at the two equations. They are both written in the slope-intercept form, y = mx + b, where m = slope, and b = y-intercept. They have the same slope (m = -3) and different y-intercepts (9 and 3), so they are equations of two different lines, but since the slopes are the same, the lines are parallel. Since the lines never intersect, there is no solution.
Answer: No solutions

(iii) sin (90° - A) cos (90° - A)=tanA/
1+tan²A
Answer:
See below
Step-by-step explanation:
[tex]A=\theta[/tex]
[tex]$\sin(90\º - \theta) \cos(90\º - \theta) = \frac{ \tan(\theta)}{1+ \tan^2(\theta)}$[/tex]
According to cofunctions identities:
[tex]\boxed{\sin(90\º - \theta)=\cos(\theta)}[/tex]
[tex]\boxed{\cos(90\º - \theta)=\sin(\theta)}[/tex]
[tex]$\cos(\theta) \sin(\theta) = \frac{ \tan(\theta)}{1+ \tan^2(\theta)}$[/tex]
Once
[tex]$\tan(\theta)=\frac{\sin(\theta)}{\cos(\theta)} $[/tex]
[tex]$\cos(\theta) \sin(\theta) = \frac{ \frac{\sin(\theta)}{\cos(\theta)}}{1+ \frac{\sin^2(\theta)}{\cos^2(\theta)}}$[/tex]
Take
[tex]$1+\frac{\sin^2(\theta)}{\cos^2(\theta)}}=\frac{\sin^2(\theta) + \cos^2(\theta)}{\cos^2(\theta)} $[/tex]
[tex]$\cos(\theta) \sin(\theta) = \frac{ \frac{\sin(\theta)}{\cos(\theta)}}{\frac{\sin^2(\theta) + \cos^2(\theta)}{\cos^2(\theta)} }}$[/tex]
[tex]$\cos(\theta) \sin(\theta) = \frac{\sin(\theta)}{\cos(\theta)} \cdot \frac{\cos^2(\theta)}{\sin^2(\theta) + \cos^2(\theta)} }$[/tex]
[tex]$\cos(\theta) \sin(\theta) = \frac{\sin(\theta)}{\cos(\theta)} \cdot \frac{\cos^2(\theta)}{\sin^2(\theta) + \cos^2(\theta)} }$[/tex]
[tex]$\cos(\theta) \sin(\theta) = \frac{\sin(\theta)\cos(\theta)}{\sin^2(\theta) + \cos^2(\theta)} }$[/tex]
Once
[tex]\boxed{\sin^2(\theta) + \cos^2(\theta)=1}[/tex]
[tex]$\cos(\theta) \sin(\theta) = \frac{\sin(\theta)\cos(\theta)}{1 }$[/tex]
[tex]$\cos(\theta) \sin(\theta) = \sin(\theta)\cos(\theta)$[/tex]
[tex]$\therefore \sin(90\º - \theta) \cos(90\º - \theta) = \frac{ \tan(\theta)}{1+ \tan^2(\theta)}$[/tex]

FIND THE SUM OF 20 TERMS OF THE ARITHMETIC SERIES IN WHICH 3rd TERM IS 7 AND 7th TERM IS 2 MORE THAN THREE TIMES ITS 3rd TERM
Answer:
740
Step-by-step explanation:
The n th term of an arithmetic series is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given a₃ = 7 and a₇ = (3 × 7) + 2 = 21 + 2 = 23 , then
a₁ + 2d = 7 → (1)
a₁ + 6d = 23 → (2)
Subtract (1) from (2) term by term
4d = 16 ( divide both sides by 4 )
d = 4
Substitute d = 4 into (1)
a₁ + 2(4) = 7
a₁ + 8 = 7 ( subtract 8 from both sides )
a₁ = - 1
The sum to n terms of an arithmetic series is
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ] , thus
[tex]S_{20}[/tex] = [tex]\frac{20}{2}[/tex] [ (2 × - 1) + (19 × 4) ]

A ball will be drawn from a bag containing 20 balls numbered 1 through 20 . If each ball is equally likely to be drawn, what is the probability that the number on the ball drawn will be even or less than 5 ?
Answer:
7/10
Step-by-step explanation:
20 balls.
10 even, 10 odd.
4 numbers less than 5.
That is 14/20 --> 7/10
Most likely.
Probability that the number on the ball drawn will be even or less than 5
= 3/5
What is probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event. For an experiment having 'n' number of outcomes, the number of favorable outcomes can be denoted by x. The formula to calculate the probability of an event is as follows.
Probability(Event) = Favorable Outcomes/Total Outcomes = x/n
Given,
Total no. of balls = 20
All balls are numbered with numbered 1 through 20.
Balls with even numbers or less than five:
1, 2, 3, 4, 6, 8, 10, 12, 14, 16, 18, 20
No. of balls with even numbers and less than five = 12
Probability that the number on the ball drawn will be even or less than 5 = No. of balls with even numbers or less than five/Total balls
= 12/20
Probability = 3/5
Hence, 3/5 is the probability that the number on the ball drawn will be even or less than 5.

The correct option are;
On a coordinate plane, a cubic function has an x-intercept of (0, 0)
On a coordinate plane, an oval is in quadrant 1
Step-by-step explanation:
Rotational symmetry of a shape is a shape that when it is rotated on its axis to a given angle less than one complete revolution, the shape looks exactly like the pre-image or original appearance of the shape
For a cubic function that has x-intercept = (0, 0) we have;
y = f(x) = a·x³ + b·x² + c·x
Has the shape f a fan blade and therefore, looks the sane when rotated when rotated through 180°
