Answer:
1st is 26.376 2nd is n
Step-by-step explanation:
2pie X r so. 2 X3.14X4.2
Answer:
26.376 cm
4 is the constant
Step-by-step explanation:
C = [tex]2\pi r[/tex]
To find the circumference, we first need to find the radius. The radius of a circle is half the diameter, so divide 84 by 2:
84/2 = 42
The radius is 42. Now we can solve for the circumference:
C = 2[tex]\pi[/tex](42)
C = 84[tex]\pi[/tex]
C = 263.89
The circumference is approximately 263.89 mm. Now we need to convert the millimeters to centimeters. There are 10 millimeters in 1 centimeter, so divide the circumference by 10:
263.89/10 = 26.389
The circumference is approximately 26.389 cm. The answer choice that our answer is closest to is the first answer choice.
4 + 2n
The constant in an expression is the value that doesn't change. After 2 and n are multiplied, that value will be different, so their values aren't constant. So, in this expression, 2 is the coefficient, n is the variable, and 4 is the constant.

Jelly beans cost $15.98 for a 2 kg bag. At this rate, how much would 7 kg cost
Answer:
lets see every 2kg bag its 15.98 so every 4kg its 31.96 and for every 6kg its 47.94 so if every 1kg its 7.99 so add 47.94 + 7.99 you get 55.93

Find the coordinates of point P along the directed line segment AB so that AP to PB is the given ratio. A(10, 8), B(18, 12); 1 to 3
Answer:
The coordinates of P are (12,9)
Step-by-step explanation:
Equations
We are given the endpoints of the segment AB: A(10,8) B(18,12).
It's required to find the coordinates of point P(x,y) along the segment AB such that:
[tex]\displaystyle \frac{AP}{PB}=\frac{1}{3}[/tex]
The ratio of the distances is the same as the ratio of their respective coordinates:
[tex]\displaystyle \frac{x_{AP}}{x_{PB}}=\frac{1}{3}[/tex]
[tex]\displaystyle \frac{y_{AP}}{y_{PB}}=\frac{1}{3}[/tex]
Since
[tex]x_{AP}=x_P-x_A=x-10[/tex]
[tex]x_{PB}=x_B-x_P=18-x[/tex]
Then:
[tex]\displaystyle \frac{x-10}{18-x}=\frac{1}{3}[/tex]
Multiplying by 3 (18-x):
3( x - 10 )= 18 - x
3x - 30 = 18 - x
Adding x and 30:
4x = 48
x = 12
Similarly:
[tex]\displaystyle \frac{y-8}{12-y}=\frac{1}{3}[/tex]
Multiplying by 3 (12-y):
3( y - 8 ) = 12 - y
3y - 24 = 12 - y
Adding y and 24:
4y = 36
y = 9
The coordinates of P are (12,9)
Find the ordered triple of these equations.
X + y + z = 12
y = 1
X - Y - Z = 0
Answer:
the ordered triple of these equations will be:
(x, y, z) = (6, 1, 5)
Step-by-step explanation:
Given the equations
[tex]x + y + z = 12[/tex]
[tex]y=1[/tex]
[tex]x - y - z = 0[/tex]
As
[tex]y=1[/tex]
We can get the value of x by adding the first and third equation
so
[tex]x + y + z = 12[/tex]
[tex]x-y-z=0[/tex]
so the equations become
[tex]x+x+y-y+z-z=12+0[/tex]
[tex]2x = 12[/tex]
[tex]x = 6[/tex]
Putting x = 6 and y=1 in the first equation [tex]x+y+z=12[/tex]
[tex]6 + 1+ z = 12[/tex]
[tex]7 + z = 12\\z = 12 -7[/tex]
[tex]z = 5[/tex]
Therefore, the ordered triple of these equations will be:
(x, y, z) = (6, 1, 5)

What are the slope and the y-intercept of the graph of the linear function shown on the grid?
(-6, 0) (2,-2)
Answer:
hi! the slope formula is y2-y1 / x2-x1 ! so (-6,0) (2,-2)
your x1 is -6 and y1 is 0 and x2 is 2 and y2 is -2!
using the formula, -2-0/2--6 is 4
so your slope is 4!
the y intercept is solved by
the slope intercept formula y= mx+b
I hope you've memorized both formulas!
b is your y intercept so let's set the equation up!
pick a point it can be either point we'll do (-6,0)!
now y=mx + b
m is your slope and y is the y coordinate of the point (-6,0) that we chose!
b is what we will solve
so! 0=4(-6)+b
0= -24 + b
now it's basic algebra!
24= b
I hope this helps!
In conclusion, slope is 4 and y intercept is 24
memorize slope formula and slope intercept formula and you can do this!
Help me plz guys and girls plz
Answer:
The first one
Step-by-step explanation:
since you're subtracting 12, it will be -8
the -8/4 = -2
Answer:
It is the first answer choice b<4 or b>-2
Step-by-step explanation:
Solve the first inequality like so
6b<24
divide by 6 on both sides
b<4
Now for the second inequality solve like so
4b+12>4
Subtract 12 on both sides
4b>-8
Divide on both sides by 4
b>-2
This leaves us with only one answer choice which is A -
b<4 or b>-2

What is the measure of <C ? O 38° O 76° O 90° O 152°
Answer:
Your answer is 38 degrees.
Step-by-step explanation:
The question was solved through the properties of a circle. The angle subtended at the center is double the angle subtended at the circumference.
Hope I helped, happy schooling!!
The measure of <C is 38°. The answer is the first option 38°
Circle theoremsFrom the question, we are to determine the measure of <C.
In the diagram, <C is an angle on a part of the circumference.
From the given information, the angle subtended by arc AB at the center of the circle is 76°
From one of the circle theorems we have that
The angle subtended by an arc of a circle at its center is twice the angle it subtends anywhere on the circle's circumference
Therefore,
2 × <C = 78°
<C = 76° ÷ 2
<C = 38°
Hence, the measure of <C is 38°. The answer is the first option 38°

Solve for x in the equation x2 - 8x+41 - 0
X=-41 371
x= -4 + 5i 0 X-4+ 371
x = 4 + 5/
Answer:
x= 4+5i
Step-by-step explanation:
The values of x in the given quadratic equation, x²-8x+41 = 0 are x = 4+5i or x = 4-5i
What is quadratic equation?A quadratic equation is any equation that can be rearranged in standard form as where x represents an unknown value, and a, b, and c represent known numbers, where a ≠ 0.
Given is a quadratic equation, x²-8x+41 = 0, we need to find the values of x,
Since, 41 is a prime number, which can not be factorized so, we will use quadratic formula,
x = [-b ± √(b²-4ac)] / 2a
Here, a = 1, b = -8, c = 41
Therefore,
x = [8 ± √(8²-4(41))] / 2
= [8 ± √(64-164)] / 2
= [8 ± √(-100)] / 2
= [8 ± 10i] / 2
= [4 ± 5i]
Therefore, x = 4+5i or x = 4-5i
Hence, the values of x in the given quadratic equation, x²-8x+41 = 0 are x = 4+5i or x = 4-5i

Answer:
The equation for this line in slope-intercept form (y = mx + b) is y = [tex]\frac{5}{4}[/tex]x + 2, because the rise (5) over the run (4) is the slope aka 'm', and the line touches the y-axis at the point (0,2) In this ordered pair the y-value is 2, so the y-intercept, or 'b', is equal to 2.
