Answer:
The green box is -3
Step-by-step explanation:
You are reading from a graph, so it is more important perhaps, to pick clear points rather than easy to handle points.
The easiest two points you could use would be
(0,4)
(1, 1)
Slope
m = (y2 - y1)/(x2 - x1)
y2 = 4
y1 = 1
x2 = 0
x1 = 1
m = (4-1)/(0 -1)
m = 3/-1 = - 3
Y intercept
b = 4 from the point 0,4
Line
y = - 3x + 4

A piece of wire 100 cm long is cut into two pieces, each to be bent to make a square. The length of a side of one square is to be 4 cm longer than the length of a side of the other. How should the wire be cut?
Answer:
The two pieces will be 42 and 58 cms long.
Step-by-step explanation:
Let the length of the smallest square be x cm.
Then the length of the other will be x + 4 cm
So, as there are 4 sides in a square, we have the equation:
4x + 4(x + 4) = 100
8x + 16 = 100
8x = 84
x = 10.5 cm.
So we need 4*10.5 = 42 cms for one square and 4 * 14.5 = 58 cms for th other square.

find a unit vector in the same direction as the vector (-4,7)
To find out the unit vector in the same direction of other vector, we can calculate the magnitude of its vector and then divide all coordinates by the magnitude, remember that the definition of a unit vector is that its magnitude is 1.
We can calculate the magnitude of a 2D vector as
[tex]\Large\displaystyle\text{$\begin{gathered}v = \left(x, y\right)\\ \\\|v\| = \sqrt{x^2 + y^2}\end{gathered}$}[/tex]
I'll call the vector (-4, 7) as v, so the magnitude of v is
[tex]\Large\displaystyle\text{$\begin{gathered}v = \left(-4, 7\right)\\ \\\|v\| = \sqrt{\left(-4\right)^2 + \left(7\right)^2}\\ \\\|v\| = \sqrt{65}\\ \\\end{gathered}$}[/tex]
So the unit vector that i'll call as v with an hat is
[tex]\Large\displaystyle\text{$\begin{gathered}\hat{v} = \frac{v}{\|v\|}\end{gathered}$}[/tex]
The vector divided by its magnitude, when we divide a vector by a scalar it's the same as divide all the coordinates, so
[tex]\Large\displaystyle\text{$\begin{gathered}\hat{v} = \frac{v}{\|v\|}\\ \\\hat{v} = \frac{v}{\sqrt{65}}\\ \\\hat{v} = \frac{\left(-4, 7\right)}{\sqrt{65}}\\ \\ \boxed{\hat{v} = \left(-\frac{4}{\sqrt{65}}, \frac{7}{\sqrt{65}}\right)}\end{gathered}$}[/tex]
We can also remove the square root from the denominator, then
[tex]\Large\displaystyle\text{$\begin{gathered}\hat{v} = \left(-\frac{4}{\sqrt{65}}, \frac{7}{\sqrt{65}}\right)\\ \\\hat{v} = \left(-\frac{4}{\sqrt{65}}\frac{\sqrt{65}}{\sqrt{65}}, \frac{7}{\sqrt{65}}\frac{\sqrt{65}}{\sqrt{65}}\right)\\ \\\hat{v} = \left(-\frac{4\sqrt{65}}{65}, \frac{7\sqrt{65}}{65}\right)\\ \\\end{gathered}$}[/tex]

Step-by-step explanation:
In triangle ABC, a = 3, b = 5, and c = 7. Find the approximate value of angle A.
22°
38°
142°
158°
9514 1404 393
Answer:
a) 22°
Step-by-step explanation:
Side 'a' is the shortest side, so angle A will be the smallest angle. Its value must be less than 60°, eliminating the last two answer choices. The actual value can be found from the Law of Cosines.
a² = b² +c² -2bc·cos(A)
cos(A) = (b² +c² -a²)/(2bc) = (5² +7² -3²)/(2(5)(7)) = 65/70
A = arccos(65/70) ≈ 21.7868°
Angle A is about 22°.
the relations {(2,-5),(8,-5),(3,4),(a,0)} is not a function. what are the possible values of a?
Please show answer
Hey there!
A function is like a machine. You put numbers in it and it gives you one number. You can end up with the same output, but you cannot put in the same number multiple times and get different results. It gives you the same number if you do the same one. Functions cannot have multiple outputs for the same input.
We see here that this relation is not a function. So, we can repeat 2, 8, or 3 to get the corresponding y-value and also 0. For example, a could be 2 and it has 2 outputs which would be -5 and 0. This makes it not a function, so our possible values will be 2, 8, and 3.

Mrs. Jones is handing out candy to trick-or-
treaters. She gives out candy bars to kids in
costume and small packages of gummies to kids
without a costume. The candy bars cost $0.80,
and the gummies cost $0.25. At the end of the
night, 100 children visited Mrs. Jones's home,
and she gave out $69.00 in candy. How many
children who visited Mrs. Jones's home were
wearing a costume?
A. 20
B. 50
C. 69
D. 80
E. 92
Hello!
Firs things first, lets write down what we needed to put in the equation.
Candy bars = kids with costumes
Gummies = kids with no costume
$0.80 per candy bar
$0.25 per gummies
100 children visited Mrs. Jones.
She gave out $69 candy
We have two equations to make!
x + y = 100
0.80x + 0.25y = 69
Now lets solve for x!
x + y = 100
0.80x + 0.25y = 69
Let pick a number that adds up to 100,
80 + 20 = 100
now lets plug those numbers into the equation.
0.80(80) + 0.25(20) = 69
64 + 5 = 69
69 = 69
now we know that,
x=80
y=20
but what does x and y represent?
x represents kids in costume
y represents kids in no costumes
What is the question asking?
How many children who visited Mrs. Jones's home were wearing a costume?
x represents kids in costume
so, the answer is 80,
80 kids were wearing a costume.
I hope this helps,
Have a wonderful day!
The distance an object travels is determined by how fast it goes and for how long it moves. If an object's speed
remains constant, the formula is d-ros, where d is the distance, r is the speed, and t is the time.
If you drive at 50 miles per hour for 5 hours, how far will you have traveled?
a .200 miles
b .10 miles
C. 250 miles
d .300 miles
Please select the best answer from the choices provided
Answer:
250 miles
Step-by-step explanation:
Speed = Distance/Time
Speed given = 50 m/hr
Distance = ?
Time = 5 hrs
Distance = Speed × Time
= 50 m/hr × 5 hr
Ans = 250 miles.

Just took the test on Edge it is correct.
Considering the table given, it is found that the value of x for which f(x) = -3 is of x = -7.
What is the table representing the function?The table is a set of points (x, f(x)), hence from it we get that it has these following points:
f(-7) = -3;f(-3) = 5;f(2) = -4;f(4) = -8;Hence, the value of x for which f(x) = -3 is of x = -7.

The dwarf planet Eris has no atmosphere and has been easier to measure than Pluto. At its
largest, the diameter of Eris is 2,338 km. Using 2376.6 km as the diameter of Pluto. As a
percent difference, how much larger is Pluto than Eris?
Answer:
1.6%
Step-by-step explanation:
2376/2338= 1.016
1.016-1 = .016 * 100
1.6%
hope it helps :)
The percent difference is 1.6% Eris larger than Pluto.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
What are Arithmetic operations?Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
+ Addition operation: Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
/ Division operation: Divides left-hand operand by right-hand operand
For example 4/2 = 2
Given that
The diameter of Eris is 2,338 km and
The diameter of Pluto is 2376.6 km
So the ratio of diameter = 2376/2338 = 1.016
The percent difference = (1.016 - 1)×100
The percent difference = 0.016 × 100
The percent difference = 1.6%
Hence, the percent difference is 1.6% Eris larger than Pluto.
