Answer:
4(x -4)(2x +1)
Step-by-step explanation:
8x² -16 -28x , rearrange it so the exponents will be going form highest to lowest
8x²-28x -16, factor 4
4(2x² -7x -4),
to get 2x² we need to multiply an x and a 2x
to get -4 we need to multyply 1 and -4 or -1 and 4 or 2 and -2 (can use trial and error method here)
4(x -4)(2x +1)
Check
4(x-4)(2x+1) = (4x -16)(2x+1) = 8x² +4x -32x -16 = 8x²-28x -16
If Betty makes monthly deposits at the end of each month in an account that earns 8% interest compounded monthly,
(a) How much would she have to deposit every month in order to have $40,000 in the account in 9 years? $
(b) Find her total balance in the account at the end of three months. $
(c) Find the total amount of interest that she's earned after the 9 years. $
9514 1404 393
Answer:
(a) $254.08
(b) $767.34
(c) $12,449.36
Step-by-step explanation:
These questions are best answered by a financial calculator or app. Such are available for your phone or tablet. A spreadsheet also has built-in functions for making these calculations.
(a) FV = $40,000, i = 8% per year, n = 9 years (108 months), compounding 12 times per year. The monthly deposit needs to be $254.08.
__
(b) Payment = $254.08, n = 3 months, i = 8%/year, compounding 12 times per year. FV = $767.34.
__
(c) The sum of 108 payments of $254.08 is ...
108 × $254.08 = $27,440.64
The interest earned is enough to bring the account value to $40,000, so is ...
$40,000 -27,440.64 = $12,559.36
_____
Additional comment
The amount $254.08 is rounded down to the nearest cent, so the balance after 9 years will be $39,999.70, which is $0.30 short of $40,000. We used $40,000 as the final account balance, so overestimated the interest by $0.30.
There may be additional small changes in the values if you round interest to the nearest cent each month the way a financial institution would. It is hard to tell in these problems how accurate you're intended to be in your calculations.
pls look at attached picture i have tried asking many and no one can explain it to me
Answer: a = 0.98
Explanation: For this case we have the following table:
x | P(x)
0| 0.1296
1| 0.3456
2| 0.3456
3 | 0.1536
4| 0.0256
We can find the expected value as:
E(X)= 0*0.1296 + 1*0.3456+ 2*0.3456+ 3*0.1536+ 4*0.0256= 1.6
Now we can find the second moment like this:
E(X^2)= 0^2*0.1296 + 1^2*0.3456+ 2^2*0.3456+ 3^2*0.1536+ 4^2*0.0256= 3.52
And the variance is given by:
Var(X)= E(X^2)- [E(X)]^2 = 3.52 -(1.6^2)=0.96
Then the standard deviation is:
Sd(X)= sqrt(0.96)=0.98

Answer:
Length= 6x²-5
P=12x²+4x+20
Step-by-step explanation:
A=L×W
L=A/W
L=(6x² - 7x + 14)/(2x-5)
L=6x²-5
P= 2 (L+W)
P= 2[(2x-5)+(6x²-5)]

Answer:
[tex]\mathsf{\frac{4}{3} \:\times\frac{1}{2}\: =\: \frac{4}{3} \:\div\frac{2}{1}}[/tex]
Step-by-step explanation:
The mathematical operation of division is the opposite of multiplication. When you divide two fractions, you will have to take the reciprocal of the divisor, and multiply it with the dividend.
In the given equation, [tex]\mathsf{\frac{4}{3} \:\times\frac{1}{2}\: =\: \frac{4}{3} \:\div\:?}[/tex], we can rewrite this as: [tex]\mathsf{\frac{4}{3} \:\div\:?\:=\:\frac{4}{3} \:\times\frac{1}{2}}[/tex].
As previously mentioned, division is opposite of multiplication. Since the multiplicand in the multiplication of two fractions is ½, then we can assume that the divisor (or the missing fraction) must be the reciprocal of ½, which is [tex]\mathsf{\frac{2}{1}\:or\:2}[/tex].
Therefore, the missing fraction that completes the given mathematical statement is [tex]\mathsf{\frac{2}{1}\:or\:2}[/tex].
[tex]\mathsf{\frac{4}{3} \:\times\frac{1}{2}\: =\: \frac{4}{3} \:\div\frac{2}{1}}[/tex]

(02.03 MC) The figure shows two triangles on a coordinate grid: A coordinate grid is shown from positive 6 to negative 6 on the x-axis and from positive 6 to negative 6 on the y-axis. A triangle ABC is shown with vertex A on ordered pair negative 4, 1 vertex B on ordered pair negative 3,1, and vertex C on ordered pair negative 4, 4. Another triangle A prime B prime C prime is shown with vertex A prime on ordered pair 4, 4, vertex B prime on ordered pair 3, 4, and vertex C prime on ordered pair 4,1. What set of transformations is performed on triangle ABC to form triangle A′B′C′? (5 points) Group of answer choices A 180-degree counterclockwise rotation about the origin, followed by a translation 5 units down A translation 5 units down followed by a 180-degree counterclockwise rotation about the origin A 270-degree counterclockwise rotation about the origin, followed by a translation 5 units to the right A translation 5 units to the right, followed by a 270-degree counterclockwise rotation about the origin
Answer:
Step-by-step explanation:
A translation 5 units down followed by a 180-degree counterclockwise rotation about the origin
Step-by-step explanation:
The figure is obviously rotated 180°. If the rotation is first, the image would be in the 4th quadrant, where it would stay after translation downward.
If the translation is downward first, it would be in the 3rd quadrant, moving to the first quadrant after rotation by 180°. This is the apparent sequence of transformations:

The perimeter of a rectangle is at least 32 cm. The length of the rectangle is 9 cm. What are the possible widths of the rectangle? Show your work.
Answer:7 on both sides all together 14
Step-by-step explanation:32 is length and width combined so 18 all together for width which leaves 14 cm for width so both sides are 7
Answer:
width ≥ 7 cm
Step-by-step explanation:
The perimeter formula is ...
P = 2(L +W)
We have P ≥ 32 and L = 9. We want to find W. (Dimensions are cm.)
2(9 +W) ≥ 32 . . . . substitute for P and L
2W ≥ 14 . . . . . . . subtract 18 and simplify
W ≥ 7 . . . . . . . . . divide by 2
Possible widths are at least 7 cm.

What is the length of the longest side of the triangle if the left side is 2x+12 and the bottom number is 6x-2 and the right side is 5x-9
Answer:
Depends on the value of x. If x = 3, the triangle has sides 18, 6, 16 which satisfies the triangle inequality, so 2x+12 is longest in this case. If x is very large, the triangle inequality is still satisfied, and 6x-2 is the longest side.
Step-by-step explanation:
jill and her brother jack both walked up a hill. they started at the same time, but jill arrived at the top ten minutes before jack. while resting at the top, jack calculated that if he had walked 50% faster and jill had walked 50% slower, then they would have arrived at the top at the same time. how long did jack actually take to walk up to the top of the hill?
It took Jack 15 minutes to walk up to the top of the hill.
Let v = Jill's speed and v' = Jack's speed. Let t = time it takes Jill to walk up to the top of the hill, since Jill arrives 10 minutes earlier, Jack's time, t' = t + 10.
Since the distance covered by both Jack and Jill is the same, we have that
vt = v't'
vt = v'(t + 10)
Since Jack calculated that if he walked 50 % slower and Jill 50 % faster, they would arrived at the top at the same time, Jack's new speed is V = v' + 0.5v'. (since there is a 50 % increase in speed).
Also, Jill's new speed is V' = v - 0.5v (since there is a 50 % decrease in speed)
Since they both arrive at the top at the same time, T, and the distance covered is equal, we have that VT = V'T
(v' + 0.5v')T = (v - 0.5v)T
1.5v' = 0.5v
v'/v = 1.5/0.5
v'/v = 3
From (1)
vt = v'(t + 10)
(v'/v)t = t + 10
3t = t + 10
3t - t = 10
2t = 10
t = 5 minutes
Since Jack's time t' = t + 10, substituting t = 5 into the equation, we have
t' = t + 10
= 5 + 10
= 15 minutes
So, it took Jack 15 minutes to walk up to the top of the hill.

What should be the first step to solve the equation?
2x + 9(x - 1) = 8(2x + 2) - 5
O Combine like terms on each side of the equation.
O Use the distributive property on each side of the equation.
Use the subtraction property of equality to subtract 5 from each side of the equation.
Use the addition property of equality to add 2x to each side of the equation.
Answer:
Your answer would be to Use the distributive property on each side of the equation.
Step-by-step explanation:
You would first expand the equation by using the distributive property on each side of the equation
[tex]2x + 9(x - 1) = 8(2x + 2) - 5\\2x + 9(x) 9(-1) = 8(2x) 8(2) - 5\\2x + 9x-9 = 16x+16 - 5[/tex]
Then you would combine like terms on both sides
[tex]2x+9x-9=11x-9\\16x+16-5=16x+11[/tex]
Now you solve for x
[tex]11x-9=16x+11[/tex]
You subtract 11x from both sides
[tex]11x-9=16x+11\\-11x=-11x[/tex]
Then you subtract 11 from both sides
[tex]-9=5x+11\\-11=-11[/tex]
Then you divide 5 on both sides
[tex]-20=5x[/tex]
[tex]\frac{-20}{5} =\frac{5x}{5}[/tex]
[tex]x=-4[/tex]

Use the table to determine the total amount paid on a 20 year fixed loan, at 5.5%, of $160,000. A 5-column table with 4 rows titled Monthly Payments per 1000 dollars of mortgage. Column 1 is labeled Interest Rate (percent) with entries 5, 5.5, 6, 6.5. Column 2 is labeled 10 Years with entries 10.61, 10.86, 11.11, 11.36. Column 3 is labeled 20 years with entries 6.60, 6.88, 7.17, 7.46. Column 4 is labeled 30 years with entries 5.37, 5.68, 6.00, 6.33. Column 5 is labeled 40 years with entries 4.83, 5.16, 5.51, 5.86. a. $160,000 c. $264,192 b. $203,254 d. $176,000 Please select the best answer from the choices provided A B C D Mark this and return
Answer:
c. $264,192
Step-by-step explanation:
Column 3, labeled 20 Years, would be the column you want for a 20-year loan.
Row 2, labeled 5.5%, would be the row you want for a 5.5% loan.
The value in the table at row 2 of column 3 appears to be 6.88. The is the amount of the payment per $1000 of loan value. A $160,000 loan will have a monthly payment that is 160 times $6.88 = $1100.80.
The 20-year loan will be paid back with 20×12 = 240 monthly payments. The total amount of those payments will be ...

Step-by-step explanation:
For x=10, the marked angles are ...
(7x-5)° = (70 -5)° = 65°
(10x +15)° = (100 +15)° = 115°
(12x -5)° = (120 -5)° = 115°
(8x -25)° = (80 -25)° = 55°
We notice that the alternate interior angles between lines c and d are congruent, so those lines are parallel. The acute angle at line b is supplementary to the obtuse angle at lines c and d, so line b is parallel to those two lines, as well.
The angle at line e is not related to any of the other angles, so that line is not parallel to any of the others shown.
