Joyce is thinking of a 3 - digit number. Her number has the digits 8,4, and 6. To the nearest hundred, it rounds to 600. What is the number?
Answers
Answer:
684 :)
Step-by-step explanation:
Joyce's number is 648.
To determine Joyce's number, we need to use the information that it has the digits 8, 4, and 6, and it rounds to 600 to the nearest hundred. Here's how we can approach this:
The number must round to 600, so it must be closer to 600 than to 500 or 700. This means it must be in the range 550 to 649.We need to form numbers using the digits 8, 4, and 6: 486, 468, 846, 864, 684, and 648.Comparing these numbers, only 648 falls within the range of 550 to 649.Therefore, Joyce's number is 648.

Step-by-step explanation:
His formula makes the most sense to the sequence.
The recursive formula to describe a sequence is shown below
a1=4
an=an-1+2n
State the first four terms of this sequence.
Answers
Given that the recursive formula for a sequence is [tex]a_n=a_{n-1}+2n[/tex]
The first term of the sequence is [tex]a_1=4[/tex]
We need to determine the first four terms of the sequence.
Second term:
The second term of the sequence can be determined by substituting n = 2 in the recursive formula.
Thus, we have;
[tex]a_2=a_{2-1}+2(2)[/tex]
[tex]a_2=a_{1}+2(2)[/tex]
[tex]a_2=4+4[/tex]
[tex]a_2=8[/tex]
Thus, the second term of the sequence is 8.
Third term:
The third term of the sequence can be determined by substituting n = 3 in the recursive formula.
Thus, we have;
[tex]a_3=a_{3-1}+2(3)[/tex]
[tex]a_3=a_{2}+2(3)[/tex]
[tex]a_3=8+6[/tex]
[tex]a_3=14[/tex]
Thus, the third term of the sequence is 14.
Fourth term:
The fourth term of the sequence can be determined by substituting n = 4 in the recursive formula.
Thus, we have;
[tex]a_4=a_{4-1}+2(4)[/tex]
[tex]a_4=a_{3}+2(4)[/tex]
[tex]a_4=14+8[/tex]
[tex]a_4=22[/tex]
Thus, the fourth term of the sequence is 22.
Hence, the first four terms of the sequence is 4, 8, 14, 22.

Answers
(A) The prism could be a cube with a side length of 10 mm.
(B) It is possible for the length to be 1,000 mm.
(D) It is possible that the length is 2.5 mm.
Explanation:
Volume = l×w×h
where l is the length, w is the width and h is the height
It is possible that the length is 2.5 mm
Then volume = 2.5 × 10 ×40 = 1000 mm³
It is possible for length to be 1000 mm
Then volume = 1000 × 0.1 × 10 = 1000 mm³
The prism could be a cube of length 10 mm
Then volume = 10 × 10 × 10 = 1000 mm³

The major and minor axes of an ellipse are 25 inches and 4 inches in length. What is the area of the ellipse?
Answers
Answer:
Therefore, the area of the ellipse is:
Area = 78.5 inches
Step-by-step explanation:
The formula to find the area of the ellipse is
[tex]\:a\:\times \:b\:\times \:\pi[/tex]
The major axis of an ellipse = 25 inches
The minor axis of an ellipse = 4 inches
The value of a = major axis/2 = 25/2 = 12.5 inchesThe value of b = minor axis/2 = 4/2 = 2 inchesThus
The area of the ellipse:
Area = [tex]\:a\:\times \:b\:\times \:\pi[/tex]
[tex]=\:12.5\:\times\:2\:\times\:\pi[/tex]
[tex]=25\pi[/tex]
[tex]=78.5[/tex] inches ∵ [tex]\pi =3.14[/tex]
Therefore, the area of the ellipse is:
Area = 78.5 inches
The vertices of a polygon are P(0,4), Q(5,4), R(5-3) and S(0,-3). What is the perimeter of the polygon? (Show work please)
Answers
Answer:
The perimeter of the polygon are
PQ = 5
RS = 5
PR = √74 = 8.60
QS = √74 = 8.60
QR = 7
Step-by-step explanation:
To calculate the perimeter of a polygon, polygon is like a coordinate with points, to find the length, we use this formula
d = √(x _2 - x_1)^2 + (y_2 - y_1)^2
Let's start from the first two vertices P ( 0 , 4) and Q(5 , 4)
x_1 = 0
y_1 = 4
x_2 = 5
y_2 = 4
PQ = √ ( 5 - 0)^2 + ( 4 - 4)^2
= √ 5^2 + 0^2
= √ 25
= 5
Between R( 5 , -3) and S ( 0 , -3)
x_1 = 5
y_1 = -3
x_2 = 0
y_2 = -3
RS = √ ( 0 - 5)^2 + ( -3 - (-3))^2
= √( -5)^2 + ( -3 + 3)^2
= √ 25 + 0
= √ 25
= 5
Between P( 0 , 4) and R (5 , -3)
x_1 = 0
y_1 = 4
x_2 = 5
y_2 = -3
PR = √( 5 - 0)^2 + ( -3 - 4)^2
= √ 5^2 + (-7)^2
= √ 25 + 49
= √ 74
= 8.60
Between Q ( 5 , 4) and S(0 ,-3)
x_1 = 5
y_1 = 4
x_2 = 0
y_2 = -3
QS = √ ( 0 - 5)^2 + ( -3 - 4)^2
= √ -5^2 + -7^2
= √ 25 + 49
= √ 74
= 8.60
Between Q( 5,4) and R(5 , -3)
x_1 = 5
y_1 = 4
x_2 = 5
y_2 = -3
QR = √ (5 - 5)^2 + ( -3 - 4)^2
= √ 0^2 + (-7)^2
= √ 0 + 49
= √ 49

Given the functions f(n) = 11 and g(n) = −2(n − 1), combine them to create an arithmetic sequence, an, and solve for the 31st term.
Answers
To create an arithmetic sequence using the given functions, we add the functions together and substitute the desired term. The 31st term of the arithmetic sequence is -49.
Explanation:To combine the functions f(n) = 11 and g(n) = -2(n - 1) into an arithmetic sequence, we need to find the common difference between the terms. The common difference between the terms in an arithmetic sequence is obtained by subtracting one term from the previous term. In this case, the common difference is g(n). So, the arithmetic sequence can be expressed as an = f(n) + g(n).
For the 31st term, we substitute n = 31 into the equation and calculate:
a31 = f(31) + g(31)
a31 = 11 + [-2(31 - 1)]
a31 = 11 + [-2(30)]
a31 = 11 + [-60]
a31 = -49
Therefore, the 31st term of the arithmetic sequence an is -49.

Evaluate each function at each of the four points.
Functions:
f(x) = x2 – 5x – 6
f(x) = 23 – 22 – 12
f(x) = 5.24
Points:
f(0)
f(2)
f(-1)
f(6)
Answers
1) f(0)= -6 , f(2)= -12, f(-1)= 0, f(6)= 0
2) f(0)= -12 , f(2)= -8 , f(-1)= -14 , f(6)= 168
3) f(0)= 5 , f(2)= 20, f(-1)= 2.5 , f(6)= 320
Step-by-step explanation:
1) The given function is f(x) = x² – 5x – 6.
To find the values of f(0) , f(2), f(-1), f(6) :
Substitute x=0 in f(x) = x² – 5x – 6
f(0) = -6
Therefore, f(0) = -6
Substitute x=2 in f(x) = x² – 5x – 6
f(2) = (2)² -5(2)-6
⇒ 4-10-6
⇒ 4-16
⇒ -12
Therefore, f(2) = -12
Substitute x= -1 in f(x) = x² – 5x – 6
f(-1) = (-1)² - 5(-1) -6
⇒ 1+5-6
⇒ 6-6
⇒ 0
Therefore, f(-1) = 0
Substitute x= 6 in f(x) = x² – 5x – 6
f(6) = (6)² - 5(6) -6
⇒ 36 -30 -6
⇒ 36-36
⇒ 0
Therefore, f(6) = 0
2) The given function is f(x) = x³– x²–12.
To find the values of f(0) , f(2), f(-1), f(6) :
Substitute x=0 in f(x) = x³– x²–12
f(0) = -`12
Therefore, f(0) = -12
Substitute x= 2 in f(x) = x³– x²–12
f(2) = (2)³ - (2)² -12
⇒ 8-4-12
⇒ 8-16
⇒ -8
Therefore, f(2) = -8
Substitute x= -1 in f(x) = x³– x²–12
f(-1) = (-1)³ - (-1)² -12
⇒ -1-1-12
⇒ -14
Therefore, f(-1) = -14
Substitute x= 6 in f(x) = x³– x²–12
f(6) = (6)³ - (6)² -12
⇒ 216 -36 -12
⇒ 216-48
⇒ 168
Therefore, f(6) = 168
3) The given function is f(x) = [tex]5.24^{x}[/tex]
To find the values of f(0) , f(2), f(-1), f(6) :
Substitute x=0 in f(x) = [tex]5.2^{x}[/tex]
f(0) = 5 × [tex]2^{0}[/tex]
Any number with power zero is 1.
f(0) = 5
Therefore, f(0) = 5
Substitute x=2 in f(x) = [tex]5.2^{x}[/tex]
f(2) = 5 × 2²
⇒ 5×4
⇒ 20
Therefore, f(2) = 20
Substitute x= -1 in f(x) = [tex]5.2{x}[/tex]
f(-1) = [tex]5\times2^{-1}[/tex]
⇒ 5 × 1/2
⇒ 5 × 0.5
⇒ 2.5
Therefore, f(-1) = 2.5
Substitute x= 6 in f(x) = [tex]5.2^{x}[/tex]
f(6) = [tex]5\times 2^{6}[/tex]
⇒ 5 × 64
⇒ 320
Therefore, f(6) = 320

Therefore, in both the product, the end value is 5 and not 0, 1, and 3.
Therefore, option D is correct.
If we multiply 5 by any of the odd number, we can get the end value of 5. The following examples are the valid reasons why we will get 5.

A circle has a circumference of 6. It has an arc of length 17/3. What is the central angle of the arc, in degrees?
Answers
Answer:
340 degrees
Step-by-step explanation:
So the key thing here is to notice that we are given the circumference which will allow us to find a value for the radius of the circle and hence the angle subtended by the arc (the central angle).
So the circumference of a circle = 2pi(r)
This means:
6 = 2pi(r)
Which means that
r = 6/2pi or r = 3/pi
Now we can use this value of r to find our angle in conjunction with the value of the arc length. So:
Arc length is defined by: length = θr
Where θ is our angle value.
So lets plug in:
[tex]\frac{17}{3} = (angle)\frac{3}{\pi }[/tex]
Multiply by pi to get:
[tex]\frac{17\pi }{3} = 3(angle)[/tex]
Divide by 3 to get that:
θ = 17pi/9
So if we convert that from radians to degrees we get 340 degrees.

Answers
Answer:
Step-by-step explanation:first round the fractions then add decide if it goes to 0,1/2,or 1
The best estimate for the sum of 5/6 and 3/7 by rounding to the nearest 0, 1/2, or 1 is 1.5 or 3/2.
To estimate the sum of 5/6 and 3/7, we round each addend to the nearest of the given values: 0, 1/2 (0.5), or 1. Five-sixths is closer to 1 than it is to 1/2 or 0. So, we round 5/6 to 1.
Three-sevenths is closer to 1/2 than to 1 or 0. So, we round 3/7 to 1/2. After rounding, our new equation for estimation is 1 + 1/2.
The best estimate for the sum thus becomes 1 + 1/2 which equals 1.5 or 3/2. This is a quick way to find a rough estimate of the sum without finding a common denominator or adding the actual fractions.

The sale price of 3 pepper plants after a 20% discount is $12.
Explanation:To figure out the sale price of 3 pepper plants after a 20% discount, we first calculate 20% of the regular price. The regular price of one pepper plant is $5, so 20% of $5 is $1. Therefore, the sale price of one pepper plant is $5 - $1 = $4. As Wes wants to buy 3 plants, we multiply this sale price by 3, so the total price after discount for 3 plants is $4 * 3 = $12.
So, the sale price of 3 pepper plants after a 20% discount is $12.

2/sqrt(10) simplified

Answer:
20qrt/s / as in over
Step-by-step explanation:
To simplify 2/√(10), multiply the numerator and denominator by √(10) to get √(10)/5. This process removes the square root from the denominator.
To simplify the expression 2/√(10), we rationalize the denominator. This involves removing the square root from the denominator by multiplying the numerator and the denominator by the square root of 10.
Multiply the numerator and denominator by √(10):2/√(10) × √(10)/√(10)This gives us:
(2 × √(10)) / (√(10) × √(10)) = 2√(10) / 10Simplify the expression by cancelling common factors:
2√(10) / 10 = √(10) / 5
So, the simplified form of 2/√(10) is √(10)/5.
