Answer:
distance = sqrt( 65 ) ~= 8.06
Step-by-step explanation:
To find the distance between two points, we can use the distance formula.
distance = sqrt( [x2 - x1]^2 + [y2 - y1]^2)
distance = sqrt( [-5 - 2]^2 + [3 - -1]^2)
distance = sqrt( [-7]^2 + [4]^2)
distance = sqrt( 49 + 16 )
distance = sqrt( 65 ) ~= 8.06
Cheers.
Answer: d=8.06
Step-by-step explanation:
To this the distance between two points, you would need the distance formula.
Distance Formula: [tex]d=\sqrt{(x_{2}-x_{1} )^2+(y_{2} -y_{1} )^2}[/tex]
Since we have two given points, all we have to do is plug them in.
[tex]d=\sqrt{(2-(-5) )^2+(-1 -3 )^2}[/tex] [parentheses]
[tex]d=\sqrt{(7)^2+(-4 )^2}[/tex] [exponent]
[tex]d=\sqrt{49+16}[/tex] [add]
[tex]d=\sqrt{65}[/tex] [square root]
[tex]d=8.06[/tex]
Now we know that the distance is d=8.06.

2c+3=2c+3
Answer:
All real numbers are solutions.
Step-by-step explanation:
Step 1: Subtract 2c from both sides.
2c + 3 − 2c = 2c + 3 − 2c
3 = 3
Step 2: Subtract 3 from both sides.
3 − 3 = 3 − 3
0 = 0
All real numbers are solutions.
All real numbers are solutions.
Step-by-step explanation:
Step 1: Subtract 2c from both sides.
2c + 3 − 2c = 2c + 3 − 2c
3 = 3
Step 2: Subtract 3 from both sides.
3 − 3 = 3 − 3
0 = 0
All real numbers are solutions.
F(x)=-2x^2 -5x+1
H(x)=3(x+3)^2-11
H(f(-1))=?
A.132
B. 136
C.140
D.144
Answer:
B
Step-by-step explanation:
So we have the two functions:
[tex]f(x)=-2x^2-5x+1\text{ and } h(x)=3(x+3)^2-11[/tex]
And we want to find:
[tex]h(f(-1))[/tex]
So, find f(-1) first. Substitute -1 into f(x):
[tex]f(-1)=-2(-1)^2-5(-1)+1[/tex]
Square:
[tex]f(-1)=-2(1)-5(-1)+1[/tex]
Multiply:
[tex]f(-1)=-2+5+1[/tex]
Add:
[tex]f(-1)=4[/tex]
Now, substitute this into h(f(-1)):
[tex]h(f(-1))=h(4)[/tex]
So, substitute 4 into h(x):
[tex]h(4)=3(4+3)^2-11[/tex]
Add:
[tex]h(4)=3(7)^2-11[/tex]
Square:
[tex]h(4)=3(49)-11[/tex]
Multiply:
[tex]h(4)=147-11[/tex]
Subtract:
[tex]h(4)=136[/tex]
So, our answer is B.
And we're done!

A coin bank can hold 710 coins. There are 100 coins in the bank. A student puts in 50 coins per week. How many weeks until the bank is full?
Answer: The first answer
A coin bank can hold 710 coins. There are 50 coins in the bank. A student puts in 100 coins per week. How many weeks until the bank is full?
Step-by-step explanation:
We want to see which problem can be represented with the equation:
100*x + 50 = 710.
The correct option is:
"A coin bank can hold 710 coins. There are 50 coins in the bank. A student puts in 100 coins per week. How many weeks until the bank is full?"
So, let's briefly analyze the equation.
We have the linear equation:
100*x + 50 = 710.
On the left side, we have 100 times the variable plus a constant of 50, and that must be equal to 710.
So, we start with 50, and if x counts the number of weeks, we add 100 per week.
And because that is equal to 710, we are counting the number of weeks that we need to add 100 to get to that number.
So the problem that meets these conditions is:
"A coin bank can hold 710 coins. There are 50 coins in the bank. A student puts in 100 coins per week. How many weeks until the bank is full?"

determine which of the following pairs of triangles are similar.
Triangles given in Options (b) and (c) are similar.
Theorems of similar triangles: If two angles of a pair of triangles are equal in measure, then the triangles will be similar by A-A property. If corresponding sides of two triangles are proportional, both the triangles will be similar.
From the picture attached,
a). In triangle ABC,
∠A + ∠B + ∠C = 180° [By triangle sum theorem]
60° + ∠B + 40° = 180°
∠B = 80°
Similarly, in ΔDEF,
∠D + ∠E + ∠F = 180°
60° + 85° + ∠F = 180°
∠F = 35°
Since, measure of angles of both the triangles are different in measures, triangles will not be similar.
b). In ΔABC,
∠A + ∠B + ∠C = 180°
45° + 50° + ∠B = 180°
∠B = 85°
In ΔDEF,
∠D + ∠E + ∠F = 180°
50° + 85° + ∠F = 180°
∠F = 45°
Hence, ∠C ≅ ∠D, ∠A≅ ∠F and ∠B ≅ ∠E
Since, measure of corresponding angles are equal, both the
triangles (ΔABC ~ ΔFED) will be similar.
c). Here, corresponding sides of both the triangles are proportional,
[tex]\frac{AB}{DE}= \frac{CA}{FD}= \frac{BC}{EF}[/tex]
[tex]\frac{14}{7}= \frac{12}{6}= \frac{16}{8}[/tex]
[tex]\frac{2}{1}= \frac{2}{1}= \frac{2}{1}[/tex]
Both the triangles ΔABC and ΔDEF will be similar.
Therefore, Option B and Option C are the correct options.
