Lots of points. Will mark Brainliest. Answer ASAP! A 4-digit number ends in 3. If you put the number 3 in the first position, the number will decrease by 738. Find the original 4-digit number.
Answer:
Number: 4153
Step-by-step explanation:
4153 - 738 = 3415
as we know the resulting number starts with 3 and is a 4 digit number so we fix 4 in the thousands position of original number. Subsequently we fix 4 in the hundredth position of the number after subtraction from 738
4_ _ 3 - 738 = 34_ _
now we have a 2 empty spaces and 9 number to choose from, start from the lowest .
4 1 0 3 - 738 = 3365 , 4 has to be in the hundredth position
we increment the middle numbers by four and then by 1 until we get our answer
4 1 4 3 - 738 = 3 4 0 5
4 1 5 3 - 738 = 3 4 1 5 --------- Answer

Step-by-step explanation:
A skier is trying to decide whether or not to buy a season ski pass. a daily pass cost $78. a season ski pass cost $300 the skier would have to rent skis with either pass for $25 per day.how many days will the skier have to go skiing in order to make the season pass less expensive than the day pass?
Answer:
The skier would have to to go 4 times for the season pass to be cheaper than the day stump.
Step-by-step explanation:
This is because the day pass is $103, including ski rentals. $103 times 4 is 412. Then I have to find out what the cost is for 4 ski rentals, which is 25 times 4. That means that 4 ski rentals are $100. Then I add that to the $300, and that is $400. So therefore, the season pass is cheaper after 4 times of going skiing.
What is the positive solution of x^2-36 = 5x
x^2-5x-36 =0
=》(×+4)(x-9) =0
=》 x = 9 or -4
positive solution for x is 9
For this case we must find the positive solution of the following quadratic equation:
[tex]x ^ 2-5x-36 = 0[/tex]
To find the solutions we factor, that is, we look for two numbers that when multiplied give as result -36 and when summed give as result -5.
These are:
-9 and +4
[tex]-9 * 4 = -36\\-9 + 4 = -5[/tex]

C) (25, -16), r = 10
Step-by-step explanation:
The equation of a circle: (x - w)² + (y - h)² = r², where (w, h) is the coordinate of the center, and r is the radius of the circle.
w = 25, h = -16, r = √100 = 10
So, the coordinate is (25, -16), and the radius is 10 units.
Answer:
C

What is the remainder when 2 is synthetically divided into the polynomial -3x2 + 7x - 9?
Answer:
-7
Step-by-step explanation:
When you divide a polynomial f(x) by (x-c), the remainder r will be f(c).
hence you will get the remainder by putting the 2 as value of x:
f(x) = -3x² + 7x - 9
f(2) = -3(2)² +7(2) - 9
= -3(4) + 14 - 9
= -12 + 5
remainder = -7
Final answer:
When substituting x with 2 in the polynomial -3x² + 7x - 9, you simply evaluate it directly. The calculation gives -3(2²) + 7(2) - 9, resulting in a remainder of -7.
Explanation:
To find the remainder when a polynomial is divided by a monomial like x - 2, you can use synthetic division. However, you have asked about the division of -3x² + 7x - 9 by 2, which is actually a simple polynomial evaluation, not a division problem. We will substitute x with 2 in the polynomial and find the remainder.
The polynomial is -3x² + 7x - 9. To find the remainder when we substitute x = 2, we evaluate the polynomial:
-3(2)2 + 7(2) - 9 = -3(4) + 14 - 9 = -12 + 14 - 9 = 2 - 9 = -7.
Therefore, the remainder when 2 is substituted into the polynomial -3x² + 7x - 9 is -7.

Answer:
AB = 16
Step-by-step explanation:
The perimeter is the sum of all 5 sides of the pentagon
Sum the 5 sides, equate to 69 and solve for x
12 + 3x + 10 + x + 3 + 2x + 2 = 69
6x + 27 = 69 ( subtract 27 from both sides )

Which points are on the plane curve described by the following set of parametric equations? Select TWO
X = 4t + 3 and Y = 5t^2
Answer Choices:
(-1 , -5)
(-1 , 5)
(1 , 7)
(2 , 11)
(7 , 5)
ANSWER
(-1,5)
(7,5)
EXPLANATION
The given set of parametric equations is:
[tex]x = 4t + 3[/tex]
and
[tex]y = 5 {t}^{2} [/tex]
We make t the subject in the first equation to get:
[tex]t = \frac{x - 3}{4} [/tex]
We put this into the second equation to get;
[tex]y =5( \frac{x - 3}{4} )^{2} [/tex]
When x=-1,
[tex]y =5( \frac{ - 1- 3}{4} )^{2} = 5[/tex]
Therefore (-1,5) lies on this line.
When x=7,
[tex]y =5( \frac{7 - 3}{4} )^{2} = 5[/tex]
Therefore (7,5) also lie on this line.
Which line is represented by the function f(x)=3x+5?
Answer:
Line x is represented by the function f(x)=3x + 5
Step-by-step explanation:
f(x)=3x+5; y -intercept = 5
When x = 0, y = 3(0) + 5 = 5
When x = - 2, y = 3(-2) + 5 = -1
So the coordinate points (0,5) and (-2, 1)
Look at the second line (x), it has the y-intercept at 5 and matching those 2 coordinate points above.
So answer is the second line (x)
Hello there! It is the second line, line X.
The equation asks which line is represented by the given equation, f(x)=3x+5. Well, since the equation is in y-intercept form, y = mx + b, we know m is the slope, so the slope is 3, and b is the y intercept, so they intercept is 5.
If any of the lines on the graph intersect at (0,5), or through the y axis at 5, they have a y intercept of 5 and could potentially be the correct answer. There is only one lune that does this, line x, making this the answer.

Answer:
c = 4/3
Step-by-step explanation:
3(c + 8) = 28
Since we have paranthesis, first use the dsitributive property [multiply 3 by c and 8]
3(c + 8) = 28
3c + 24 = 28
To find the value of c, you must have c alone on one side, so subtract 24 from both sides
3c + 24 = 28
3c = 4
Now, divide by 3 to both sides to get your answer
3c = 4
c = 4/3
Therefore, the answer is 4/3!
I hope this helps! :)
3 (c + 8) = 28
3 x c = 3c
3 x 8 = 24
3c + 24 = 28
3c + 24 - 24 = 28 - 24
3c = 4
3c/3 = 4/3

show how the following sequences is an arithmetic or not
please help me
Answer:
not arithmetic
Step-by-step explanation:
An arithmetic sequence has a common difference d between consecutive terms.
Given
[tex]T_{n}[/tex] = 2n² - 1
Substitute in n = 1, 2, 3, 4 to generate the first 4 terms of the sequence
[tex]T_{1}[/tex] = 2(1)² - 1 = 2 - 1 = 1
[tex]T_{2}[/tex] = 2(2)² - 1 = 8 - 1 = 7
[tex]T_{3}[/tex] = 2(3)² - 1 = 18 - 1 = 17
[tex]T_{4}[/tex] = 2(4)² - 1 = 32 - 1 = 31
check the difference between consecutive terms
7 - 1 = 6
17 - 7 = 10
31 - 17 = 14
The differences are not common hence not an arithmetic sequence

Chuck can afford a $490-per-month car payment, and he's interested in either
a convertible, which costs $28,700, or a sports car, which costs $29,200. If he
is being offered a 6-year car loan with an APR of 6%, compounded monthly
which car can Chuck afford?
A. Chuck can afford the sports car but not the convertible
B. Chuck can afford neither the convertible nor the sports car
C. Chuck can afford the convertible but not the sports car
D. Chuck can afford both the convertible and the sports car
Answer:
Option D is correct.
Step-by-step explanation:
EMI formula is :
[tex]\frac{p*r*(1+r)^{n} }{(1+r)^{n}-1 }[/tex]
Calculation for convertible car:
p = $28700
r = 6/12/100=0.005
n = [tex]6\times12=72[/tex] months
Putting the values in formula we get
[tex]\frac{28700*0.005(1.005)^{72} }{(1.005)^{72}-1 }[/tex]
= $475.67
Calculation for sports car:
p = 29200
r = 6/12/100=0.005
n = [tex]6\times12=72[/tex] months
Putting the values in formula we get
[tex]\frac{29200*0.005(1.005)^{72} }{(1.005)^{72}-1 }[/tex]
= $483.96
We can see that in both cases the EMI is below $490.
As Chuck can afford a $490-per-month car payment. So, he can afford both cars. (one car out of both)
Therefore, option D is correct. Chuck can afford both the convertible and the sports car.

A rectangle has a width of 20 m and an area of 60 m. What is the length of the rectangle? A rectangle has an area of 36mm2. All of the sides are the same length. What is the length of a single side?
Answer: 1: 3mm
Answer:2: A rectangle with 4 congruent sides is a square.
A = s^2
s^2 = A
s^2 = 36 mm^2
s = sqrt(36 mm^2)
s = 6 mm
Step-by-step explanation:
Part A. The length of the rectangle is 3 m.
Part B. The length of the single side of the rectangle or square is 6 mm.
Area of RectangleThe area of a rectangle is defined as the total surface area obtained by multiplying its length and width.
Part A
Given that the area of a rectangle is 60 square meters and the width of the rectangle is 20 m. The length of the rectangle will be given below.
[tex]a = l\times w[/tex]
Where a is the area of the rectangle, l is the length and w is the width of the rectangle.
[tex]60 = l\times 20[/tex]
[tex]l = \dfrac {60}{20}[/tex]
[tex]l = 3\;\rm m[/tex]
Thus the length of the rectangle is 3 m.
Part B.
A rectangle has equal sides and area of 36 square mm. Thus the rectangle will be a sqaure. The area of the square is the product of 2 sides.
[tex]a = s^2[/tex]
Where a is the area of the square and s is the side of the square.
[tex]36 = s^2[/tex]
[tex]s = \sqrt{36}[/tex]
[tex]s = 6 \;\rm mm[/tex]
Hence the length of the single side of the rectangle or square is 6 mm.

If the graph f(x)= 9x^2+37x+41/3x+5 has an oblique asymptote at y=3x+k what is the value of k
The value of k in the equation f(x) = (9x^2 + 37x + 41) / (3x + 5) with an oblique asymptote at y = 3x + k is k = 41.
To find the value of k in the equation f(x) = (9x^2 + 37x + 41) / (3x + 5), where f(x) has an oblique asymptote at y = 3x + k, we need to determine the relationship between the numerator and denominator as x approaches infinity.
To do this, we can perform polynomial division. Divide the numerator (9x^2 + 37x + 41) by the denominator (3x + 5). The result should give us the oblique asymptote equation y = 3x + k.
Performing polynomial division:
3x + 5 ) 9x^2 + 37x + 41
- (9x^2 + 15x)
----------------------
22x + 41
The result of the division is 22x + 41.
Therefore, the oblique asymptote equation y = 3x + k becomes y = 22x + 41.
Comparing this equation to y = 3x + k, we can see that the value of k is 41.
So, the value of k in the equation f(x) = (9x^2 + 37x + 41) / (3x + 5) with an oblique asymptote at y = 3x + k is k = 41.

find the number of moles in 15 grams if silver
Answer:0.139 moles
Step-by-step explanation:
moles =[tex]\frac{mass}{Mr}[/tex]
NOTE: molecular mass of silver is 107.8682
n= [tex]\frac{15}{107.8682}[/tex]
this will give you the final answer of
n= 0.139 moles OR 0.14 moles
Final answer:
To find the number of moles in 15 grams of silver, divide the mass by the molar mass of silver (107.87 g/mol). The result is approximately 0.139 moles of silver.
Explanation:
To find the number of moles in 15 grams of silver, we can use the molar mass of silver. First, the molar mass of silver (Ag) is 107.87 grams per mole, which is the mass of one mole of silver.
We can calculate the number of moles of silver using the formula:
Number of moles = Mass of the substance (in grams) / Molar mass of the substance (in grams per mole)
So, for silver:
Number of moles = 15 grams / 107.87 grams/mole
When we perform this calculation:
Number of moles = 0.139 moles (rounded to three decimal places)
Therefore, there are approximately 0.139 moles of silver in 15 grams of the metal.
