C.-2/7
D. 7/2
Answer:
-2/7
Step-by-step explanation:
We can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( 1-3)/( 3 - -4)
= (1-3)/( 3+4)

Answer:
Step-by-step explanation:
hello :
y=x²-10x+16 in the form y=(x-h)²+k
y= x²-2(5)(x)+16
y = x²-2(5)(x)+5²-9

middle graph
Step-by-step explanation:
Soluton
The second (middle ) graph is the only one that works.
First of all when you simplicity the right, you get y = x^2 - 1). That means that x does not go through 0,0. If you put x = 0 into x^ - 1 = 0, you get - 1. So on that basis alone both the first and third graphs are incorrect.Second, both xs in the factors are plus, so x^2 is plus, which means the graph opens upward.Find y please help !!!
Answer:
20°
Step-by-step explanation:
take the sum of 3y + 10 and y and equal it to 90° that creates an equation making it easier for you to continue
Answer:
Y = 20°let's assume the opposite angle of Y to be X
angle Y = angle X ( vertically opposite angles)
3y + 10 + X + 90° = 180° ( forming linear pair)
3y + X + 100 = 180°
X + 3y = 80° ----(1)
Y + 3y = 80°
4y = 80°
y = 20°

Solve: 8 + x/3 = 1/6 (x-6) -1
A. x = 60
B. x = -60
C. x = -36
D. There are infinitely many solutions
Answer: B -60
Step-by-step explanation: When you plug in -60 into the equation it all equals out into -12 = -12, which is true. All of the other solutions don't work.
Answer:
B. x = -60
Step-by-step explanation:
8 + x/3 = 1/6 (x-6) - 1
Multiply both sides by 6.
48 + 2x = x - 6 - 6
x = -12 - 48
x = -60
The volume of a cubical box is
54.872 cm3. The length of the side of
the box is
(b) 3.6 cm
(c) 3.8 cm
(a) 3.4 cm
(d) 3.2 cm
The sides length of the cubical box is 3.8 cm if the volume of a cubical box is 54.872 cm³ option second is correct.
What is a cube?It is defined as three-dimensional geometry that has six square faces and eight vertices.
We have a volume of a cubical box is 54.872 cm³
V = 54.872 cm³
As we know the volume of the cube:
V = side³
54.872 = side³
Taking cube root on both sides:
side = 3.8 cm
Thus, the sides length of the cubical box is 3.8 cm if the volume of a cubical box is 54.872 cm³ option second is correct.

Answer:
Approximately $594.38
Step-by-step explanation:

a is the initial amount
r is the percent of interest in decimal form
t is the time in years
y is the money after t years

Tim earns 96pounds for 16 hours. Tim earns 'time and a half' for overtime. he works 4 hours of overtime in addition to his normal 16 hours. how much does he earn altogether
find hourly rate:
96 / 16 = 6 pounds per hour
6 x 1.5 = 9 pounds per hour for overtime.
9 x 4 = 36 pounds
96 + 36 = 132 pounds total
two sides and an angle are given below. determine whether the given information results in one triangle, two triangles, or no triangle at all. solve any resulting triangle(s). b = 8, c= 7, b = 170°
Answer:
A. single triangle. C = 8.74°, A = 1.26°, a = 1.01
Step-by-step explanation:
When two sides and an angle are given, the possibility of two (or zero) triangles exists only when the given angle is opposite the shorter of the two given sides. That is not the case here, so the given measures define one unique triangle.
Law of SinesThe law of sines tells us the sides and angles have the relation ...
sin(A)/a = sin(B)/b = sin(C)/c
We can use this first to find angle C:
sin(C) = c/b·sin(B)
C = arcsin(c/b·sin(B)) = arcsin(7/8·sin(170°)) ≈ 8.7394°
∠C ≈ 8.74°
Remaining measuresNow that we know two angles, we can find the third:
A = 180° -B -C = 180° -170° -8.74° = 1.26°
∠A = 1.26°
Using the law of sines again, we can find the measure of side 'a'.
a = b·sin(A)/sin(B) = 8·sin(1.26°)/sin(170°) ≈ 1.01346
The measure of segment 'a' is about 1.01 units.
__
Additional comment
If 'a', 'b', and angle A are given, there will be zero triangles if b/a·sin(A) > 1. If b/a·sin(A) < 1 and b > a, there will be two (2) triangles. Otherwise, as here, there will be one unique triangle.
If P(n) and Q(n) are polynomials of degree j and k, respectively, then the series
Infinite
Σ P(n)/Q(n)

converges if j < k − 1 and diverges if j ≥ k – 1.
Use the polynomial test given above to determine whether the series converges or diverges.
Infinite
Σ 1/(n)^8 +7
n=1
O converges
Odiverges
Answer:
converges
Step-by-step explanation:
well the two polynomials in the series are 1 and n^8 (I'm assuming the +7 is not in the decimal but it seems to not matter). The degree of the polynomial 1 is 0 which can be represented by 1x^0. The second polynomial in the denominator has a degree of 8. So j = 0 and k = 8. Since 0 < (8-1)
0 < 7 the series converges

Michael designed an activity plan for the next week he determined that they could run at 6 miles per hour and walk at 3 mph if Michael dedicates 12 hours in the week to travel a total distance of 48 miles how many hours does Michael plan on running and walking
Answer:
Run 4 hours, Walk 8 hours.
Step-by-step explanation:
Let R be the running time
Let W be the walking time
Distance = Speed x Time
48 = 6R + 3W (equation 1)
12 = R + W (equation 2)
We will use elimination method to solve for these simulteanous equations.
Multiply Equation 2 by 3.
12x3 = 3(R+W)
36 = 3R + 3W (equation 3)
now subtract equation 3 from equation 1.
48-36 = 6R - 3R + 3W - 3W
12 = 3R
R = 12/3
= 4hours
now Substitute R into equation 2.
12 = 4 + W
W = 12 - 4
= 8
Therefore Michael plan to run for 4 hours and walk for 8 hours.
Determine the distance between two points. (9,-9) and (-6,-7)

The mean absolute deviation of the number of books is 1.84
How to determine the mean absolute deviation?The dot plot of the number of books is in the attached figure.
From the figure, we have:
x f
1 1
2 2
3 2
4 3
5 1
6 2
7 3
8 1
Start by calculating the mean using:
[tex]\bar x= \frac{\sum fx}{\sum f}[/tex]
So, we have:
[tex]\bar x= \frac{1 * 1 + 2 * 2 + 2 * 3 + 3 * 4 + 1 * 5 + 2 * 6 + 3 *7 + 1 * 8}{1 +2+2+3+1+2+3+1}[/tex]
Evaluate the sum and products
[tex]\bar x= \frac{69}{15}[/tex]
Divide
[tex]\bar x= 4.6[/tex]
The mean absolute deviation is then calculated as:
[tex]|\bar x| = \frac{\sum f|x - \bar x|}{\sum f}[/tex]
So, we have:
[tex]|\bar x|= \frac{1 * |1 -4.6|+ 2 * |2 -4.6| + 2 * |3 -4.6|+ 3 * |4 -4.6|+ 1 *| 5 -4.6|+ 2 * |6 -4.6|+ 3 *|7 -4.6|+ 1 * |8-4.6|}{1 +2+2+3+1+2+3+1}[/tex]
Evaluate the absolute difference
[tex]|\bar x|= \frac{1 * 3.6+ 2 * 2.6 + 2 * 1.6+ 3 * 0.6+ 1 *0.4+ 2 * 1.4+ 3 *2.4+ 1 * 3.4}{15}[/tex]
Evaluate the sum of products
[tex]|\bar x|= \frac{27.6}{15}[/tex]
Divide
[tex]|\bar x|= 1.84[/tex]
Hence, the mean absolute deviation of the number of books is 1.84
