Find the distance between the points (2,8) and (-1,9)
Use the distance formula: D=sqrt((x2-x1)^2+(y2-y1)^2)
Plug in:
D=sqrt((9-8)^2+(-1-2)^2)
D=sqrt(1^2+(-3)^2)
D=sqrt(1+9)
D=sqrt(10)
So the distance is about 3.16 units

Step-by-step explanation:
if 4x + 2 equals 4 what is the value of 2x + 1
To find the value of 2x + 1, we first solved for x in the equation 4x + 2 = 4, which yielded x = 1/2. Substituting this value into 2x + 1, the final answer is 2.
Explanation:The question seeks a solution for the value of 2x + 1 given that 4x + 2 = 4. We start by solving for x in the initial equation. Subtract 2 from both sides to get 4x = 4 - 2, which simplifies to 4x = 2. Dividing both sides by 4 yields x = 2 / 4, which simplifies to x = 1/2. Now that we have the value of x, we substitute it into the expression 2x + 1. So, 2(1/2) + 1 equals 1 + 1, which equals 2.
To find the value of 2x + 1, we need to determine the value of x first. Given that 4x + 2 = 4, we can start by subtracting 2 from both sides to isolate the 4x term. This gives us 4x = 2. Next, we divide both sides by 4 to solve for x. So x = 2/4 = 1/2.
Now that we know the value of x, we can substitute it into the expression 2x + 1. Plugging in x = 1/2, we get 2(1/2) + 1 = 1 + 1 = 2.
Therefore, the value of 2x + 1 is 2.
- The lengths (in feet) of the sides of a pentagon can be represented by these
expressions: 6a, a, 4, 8, and 2a. Write a simplified expression for the perimeter
of the pentagon in feet.
Answer:
9a+12
Step-by-step explanation:
The perimeter is the sum of the side lengths, so is ...
6a + a + 4 + 8 + 2a
= a(6 +1 +2) + (4 +8)
= 9a +12
Sarai is mixing a solution. She pours all the liquid from a full small beaker into a larger beaker. The liquid fills the large beaker to 15% of its capacity. If the small beaker holds 300 mL, how much does the large beaker hold?
Answer:
2000 ml
Step-by-step explanation:
Given: Sarai pours all the liquid from a full small beaker into a larger beaker.
The liquid fills the large beaker to 15% of its capacity.
The small beaker holds 300 ml.
Lets assume capacity of large beaker to hold be "x".
As given, Sarai pours all the liquid from a full small beaker into a larger beaker
∴ [tex]15\% \times x= 300\ ml[/tex]
⇒ [tex]0.15x= 300[/tex]
Dividing both side by 0.15
⇒[tex]x= \frac{300}{0.15}[/tex]
∴ [tex]x= 2000\ ml[/tex]
Hence, the large beaker can hold 2000 ml of liquid.

1 > 5 (b - 14) + 16 help me please
Answer:
b < 11
Step-by-step explanation:
Given
1 > 5(b - 14) + 16 ← distribute and simplify right side
1 > 5b - 70 + 16
1 > 5b - 54 ( add 54 to both sides )
55 > 5b ( divide both sides by 5 )
11 > b, thus
b < 11
Given f(x) = x − 7 and g(x) = x2 Find f(g(4)). f(g(4)) =
Step-by-step explanation:
Given f(x) = x − 7 and g(x) = x2 .
Find g(f(4)).
f(x) = x-7
g(x) = x^2
f(4) = 4-7 = -3
g(f(4)) = (-3)^2
(-3)^2 = 9
g(f(4)) is 9
Find f(g(4)).
f(g(4)) = f(g(4)) = 9
Find g(f(−1)).
g(f(−1)) = 64
Find f(g(−1)).
f(g(−1)) = -6

What two numbers multiply to -27 and add to 1
Answer:
3 x 9, 1 x 27, 9 x 3
Step-by-step explanation:
you have to multiple 3 x 9 to get to 27. you have to multiple 1 x 27 to get 27. you have to multiple 9 x 3 to get 27.The two numbers that multiply to -27 and add to 1 are 9 and -3.
To find two numbers that multiply to -27 and add to 1, we can use the method of factoring and algebraic manipulation.
Let the two numbers be x and y.
Step 1: Set up the equations based on the given conditions:
xy = -27 (the two numbers multiply to -27)
x + y = 1 (the two numbers add to 1)
Step 2: Solve one of the equations for one variable in terms of the other.
From the second equation, we can express y in terms of x:
y = 1 - x
Step 3: Substitute the value of y into the first equation:
x(1 - x) = -27
Step 4: Expand and rearrange the equation:
x - x^2 = -27
Step 5: Rewrite the equation in standard quadratic form:
x^2 - x - 27 = 0
Step 6: Factor the quadratic equation:
(x - 9)(x + 3) = 0
Step 7: Set each factor equal to zero and solve for x:
x - 9 = 0 --> x = 9
x + 3 = 0 --> x = -3
So, the two numbers are 9 and -3, as 9 * -3 = -27, and 9 + (-3) = 1.
In conclusion, the two numbers that multiply to -27 and add to 1 are 9 and -3. By setting up and solving the system of equations and factoring the quadratic equation, we obtained these two values that satisfy the given conditions.

A regular pentagon is dilated by a scale factor of 73 to create a new pentagon. How does the perimeter of the new pentagon compare with the original perimeter?
Question:
A regular pentagon is dilated by a scale factor of 7/3 to create a new pentagon. How does the perimeter of the new pentagon compare with the original perimeter?
Answer:
The perimeter of the new pentagon is equal to [tex]\frac{7}{3}[/tex] times the perimeter of the original pentagon
Solution:
If two figures are similar, then the ratio of its perimeters is equal to the scale factor
Let ,
z is the scale factor
x is the perimeter of the new pentagon
y is the perimeter of the original pentagon
Then,
Scale factor = ratio of perimeters
[tex]z=\frac{x}{y}[/tex]
In this problem we have
[tex]z=\frac{7}{3}[/tex]
Substituting we get,
[tex]\frac{7}{3} = \frac{x}{y}\\\\x = \frac{7}{3}y[/tex]
Which means,
[tex]perimeter\ of\ the\ new\ pentagon = \frac{7}{3} \times \text{ perimeter of the original pentagon}[/tex]
Therefore , the perimeter of the new pentagon is equal to [tex]\frac{7}{3}[/tex] times the perimeter of the original pentagon

A diamond with a side length of 5.8. An arrow points to a smaller diamond with a side length of 1.45
Answer:
The scale factor is 0.25.
Step-by-step explanation:
We have two side lengths.
First figure: A diamond with a side length of 5.8
This is the object length.
Second figure: Then a smaller diamond with a side length of 1.45
This is the image length.
The scale factor is
[tex]k = \frac{image \: length}{object \: length} [/tex]
[tex]k = \frac{1.45}{5.8} [/tex]
[tex]k = 0.25[/tex]

−3(x+5)=−9
To solve this, you need to isolate/get the variable "x" by itself in the equation:
-3(x + 5) = -9 Distribute/multiply -3 into (x + 5)
(-3)x + (-3)5 = -9
-3x - 15 = -9 Add 15 on both sides
-3x - 15 + 15 = -9 + 15
-3x = 6 Divide -3 on both sides to get "x" by itself
[tex]\frac{-3x}{-3} =\frac{6}{-3}[/tex]
x = -2
I just realized I took unnecessary steps....you could've just divided -3 then subtracted 5
-3(x + 5) = -9 Divide -3 on both sides [two negative signs cancel each other out and become positive]
x + 5 = 3 Subtract 5
x = -2

Both circle A and circle B have a central angle measuring 50°. The area of circle A's sector is 36π cm2, and the area of circle B's sector is 64π cm2. Which is the ratio of the radius of circle A to the radius of circle B?
A) 3/4
B) 3/7
C) 4/3
D) 5/7
Answer:
A) 3/4
Step-by-step explanation:
Given: Both circle A and circle B have a central angle measuring 50°.
The area of circle A's sector is 36π cm2.
The area of circle B's sector is 64π cm2.
We know, area of the circle= [tex]\pi r^{2}[/tex]
lets assume the radius of circle A be "[tex]r_1[/tex]" and radius of circle B be "[tex]r_2[/tex]"
As given, Area of circle A and B´s sector is 36π and 64π repectively.
Now, writing ratio of area of circle A and B, to find the ratio of radius.
⇒[tex]\frac{\pi r_1^{2} }{\pi r_2^{2} } = \frac{36\pi }{64\pi }[/tex]
Cancelling out the common factor
⇒ [tex]\frac{r_1^{2} }{r_2^{2} } = \frac{36 }{64}[/tex]
⇒ [tex](\frac{r_1 }{r_2} )^{2} = \frac{36 }{64}[/tex]
Taking square on both side.
Remember; √a²= a
⇒ [tex](\frac{r_1 }{r_2} ) =\sqrt{ \frac{36 }{64}}[/tex]
⇒ [tex](\frac{r_1 }{r_2} ) = \frac{6}{8}[/tex]
⇒[tex]\frac{r_1 }{r_2} = \frac{3}{4}[/tex]
Hence, ratio of the radius of circle A to the radius of circle B is 3:4 or 3/4.
