factor 8x^2+10x-3
plz explain your answer
Answers
Answer:
look I have sent you the answer of your question.
This trinomial can be factored as two binomials.
So setup two sets of parenthses.
8x² can be factored as 8x · x or 4x · 2x
and -3 can be factored as +3 · -1, -1· +3, -3 · +1, or +1 ·-3.
If the middle term in the original trinomial is even,
try pairs of even factors first if you have that option.
In this case, we have a 4x and a 2x so let's try those first.
Let's do this with all the factors of -3.
So our first possible answer could be (4x + 3)(2x - 1).
Since the product of the outer terms, -4x, plus the product of the inner, 6x,
doesn't add to our middle term, this pair doesn't work.
Now let's try (4x - 1)(2x + 3).
The product of the outer terms, 12x, plus the product of the inner, -2x,
equals the middle term in our original trinomial, this pair works.
So our answer is (4x - 1)(2x + 3).

DIMENSIONS:
THE DOUBLE: 42.6 m cubed on both the length, width, and height
THE HALF: 10.6 m cubed on both the length width and height
THE CUBE: 21.3 m cubedon both the lengrh, width, and height
MOST HEIGHT: The Double at 42.6 m cubed
Step-by-step explanation:
We know that we have 64 m cubed. First, we should find out the volume of each cube. 64 times 2 is 128. This means the Double equals 128 in volume and half of 64 is 32. this means the Half is 32 in volume. Since these are all cubes, every side is exactly the same(or else it would be a rectangle) the formula for finding volume is length times width times height, we would divide EACH of the volumes by 3. 128 divided by 3 is 42.6 meaning the doubles dimensions would be 42.6 on each part of the cube (the lenght width and height would all be 42.6) you can check this by multiplying 42.6 by 3 which takes us back to 128. For the cube we would do 64 divided by 3 which is 21.3 pn every side and 32 divided by 3 is 10.6. The one with the most height is the double.

2. Juan Pablo makes an hourly salary of $15 and time-and-a-half for any hours over 40. Last week he worked 45 hours. Explain how you would calculate his weekly gross pay, his Social Security Tax (6.2%), and his Medicare tax (145N). You don't need to actually calculate the values, just explain what mathematical processes you would use and why
Answers
Answer:
Gross = $712.5
Social security = $44.175
Medicare = $10.33125
Step-by-step explanation:
Given that :
Hourly pay = $15
Hours over 40 = 1.5 * $15 = $22.5
Total hours worked last week = 45
Total pay :
(40 * $15) + (45 - 5)*$22.5
$600 + $112.5
= $712.5
Hence, weekly gross pay = $712.5
Social security tax percent =(6.2%)
0.062 * gross = 0.062 * $712.5 = $44.175
Medicare tax percent = (1.45%)
0.0145 * $712.5 = $10.33125

ABCD is a trapezium
AD=10cm
AB=9cm
DC=3cm
Angle ABC=angled BCD=90degrees
Calculate the length of AC
Give your answer correct to 3 significant figures
Answers
Answer:
12.0 cm
Step-by-step explanation:
✔️First, find the height, BC, of the trapezium using Pythagorean Theorem.
BC² = 10² - (9 -3)²
BC² = 10² - 6²
BC² = 64
BC = √64
BC = 8 cm
✔️Find AC using Pythagorean Theorem:
AC² = AB² + BC²
AC² = 9² + 8²
AC² = 145
AC = √145
AC = 12.0415946 ≈ 12.0 (3 significant figures)
g(1)=0
g(n)=g(n-1)+n
g(2)=????
Answers
If g(1) = 0 and g(n) = g(n-1) + n, then g(2) = 2
The given relationship is:
g(1) = 0
g(n) = g(n-1) + n
g(2) = ?
Since g(1) is already known
g(2) = g(1) + 2
Note that g(1) = 0
Substitute g(1) = 0 into g(2) = g(1) + 2
g(2) = 0 + 2
g(2) = 2
Therefore, if g(1) = 0 and g(n) = g(n-1) + n, then g(2) = 2
