Answer: 4(4b - 5)(b + 5)
Step-by-step explanation:
All have a common factor of 4
4(4b^2 + 15b - 25)
--------------------------------------------------------------------------------------------------------------
Now you need to find two numbers that:
a) multiply to -100 (the a term * the c term = 4 * -25)
b) add to 15 (the b term)
After a little thinking, we can determine that the two numbers are:
20 and -5
--------------------------------------------------------------------------------------------------------------
Now we can rewrite the middle term as 20b - 5b (notice how it still equals 15b)
4(4b^2 + 20b - 5b - 25)
--------------------------------------------------------------------------------------------------------------
4((4b^2 + 20b) + (-5b - 25))
Group the terms (associative property)
--------------------------------------------------------------------------------------------------------------
Take out a common factor from each
4(4b(b + 5) - 5 (b + 5))
--------------------------------------------------------------------------------------------------------------
Now we can factor by grouping
4(4b - 5)(b + 5)
--------------------------------------------------------------------------------------------------------------

Answer: 803.84cm3
Step-by-step explanation:
The formula for finding the volume of a cylinder is πr2h.
In other words, the area of the top face's circle times the height.
To find the circle's area, we first find the radius of the circle. Since the diameter is 8cm, we divide by 2 to get the radius, which is 4cm.
4cm squared is 4cm x 4cm, which is 16cm. 16cm times 3.14 is 50.24cm squared.
Now, we have the area of the circle. 50.24cm squared!
The height is 16cm, so to find the cylinder, we times the area of the circle by the height of the cylinder! So,
16cm x 50.24cm squared = 803.84cm cubed.
The volume of the can of soup is 803.84cm cubed.
While reviewing the previous day’s arrest report, a police sergeant notices that five suspects were arrested, all of whom had either one or two previous arrests. Including yesterday’s arrests, there were 12 total arrests among them. How many suspects had less than two prior arrests?
The number of suspects had less than two prior arrests are 3.
Given that, While reviewing the previous day’s arrest report.
Let x be the number of suspects have been arrested once before and y be the number of suspects arrested twice before.
Here, x+y=5 -----(i)
2x+3y=12 -----(ii)
From equation (i), x=5-y in equation (ii), we get
2(5-y)+3y=12
10-2y+3y=12
10+y=12
y=2
Substitute y=2 in equation (i), we get
x+2=5
x=3
Therefore, the number of suspects had less than two prior arrests are 3.

Adelivery truck is transporting boxes of two sizes: large and small. The large boxes weigh 45 pounds each, and the small boxes weigh 30 pounds each. There
are 125 bones in all of the truck is corrying a total of 4800 pounds in boxes, how many of each type of box is it carrying?
Be,
x = number of large boxes
y = number of small boxes
According to the statement there are 125 boxes (large and small) in a truck, so
x + y = 125 (Equation 1)
We are also told that the large boxes weigh 45 pounds, so
45x --> Weight of an "x" number of large boxes
And the small boxes 30 pounds
30y --> Weight of a "y" number of small boxes
According to the statement, the weight of the 125 boxes (large and small) is 4800 pounds, so
45x + 30y = 4800 (Equation 2)
Our system of equations is:x + y = 125
45x + 30y = 4800
To solve this system we will apply the equalization method, which consists of solving for the same variable (x or y) in each equation.
In this case we will isolate x.
From the first equation
x = 125 - y
And from the second equation
45x = 4800 - 30y
\(\mathsf{x = \frac{4800-30y}{45} }\)
We equate both expressions
\(\mathsf{125 - y = \frac{4800-30y}{45} }\\\\\mathsf{45(125-y)=4800 - 30y}\\\\\mathsf{5625 - 45y = 4800 - 30y}\\\\\mathsf{5625 - 4800 = 45y - 30y}\\\\\mathsf{825 = 15y}\\\\\mathsf{\frac{825}{15}=y }\\\\\mathsf{55 = y}\)
There are 55 small boxes in the truck, we need to find the number of large boxes, for this we will use equation 1.
x + y = 125 (Equation 1)
x = 125 - y = 125 - 55
x = 70
VerificationSubstituting both x, y into Equation 2, we have that
45x + 30y = 4800
45(70) + 30(55) = 4800
4800 = 4800
Correct!
The answer to your math homework on 2x2 equations is: The truck has 70 large boxes and 55 small boxes.

Determine the period of the following graph
Answer:
period = 12π
Step-by-step explanation:
the period illustrates how shifting the graph by one period to the left or right results in the same function.
starting from (0, 3 )
one complete cycle to the right from here is (12π, 3 )
then period = 12π - 0 = 12π
Step-by-step explanation:
the period of a function or graph is simply the x-distance from one "top of the hill" to the next "top of the hill", or from one "bottom of the valley" to the next "bottom of the valley".
if the function has that same distance across the whole x-axis (or whatever part is valid), we are calling this a periodic function.
in our case here :
from -9pi to 3pi = 12pi
from 3pi to 15pi = 12pi
from 15pi to 27pi = 12pi
...
so, yes, it is periodic, and the period is 12pi.
A boat leaves the entrance to a harbor and travels 200 miles on a bearing of N51°E. How many miles north and how many miles east from the harbor has the boat traveled?
Thus, the boat travels x = 139.18 miles in North direction and y = 143.62 miles east from the harbor.
Explain about the components of vector:It is possible to break down a "two-dimensional vector" into its horizontal as well as vertical parts. By using the Pythagorean theorem and the vector's magnitude as the hypotenuse of a right triangle, we may determine these components of vector.
As indicated below, we must determine how far east and north the boat has moved relative to the harbour.
In this diagram, the boat is seen leaving the harbour at a bearing of N51E (measured from north to east) and a magnitude of 200 miles. The boat travelled a horizontal distance through the east, which we refer to as "x," and a vertical distance through the north, which we refer to as "y."X miles north:
cos 51 = x/200
x = 200*cos51
x = 139.18 miles
y miles east:
sin 53 = y/200
y = 200*sin 51
y = 143.62 miles
Thus, the boat travels x = 139.18 miles north and y = 143.62 miles east from the harbor.

Suppose sam deposited 1000$ every month in the beginning for his retirement fund for 20 years at 5% compounded monthly. What is value of N
To find the value of N, we need the future value of the retirement fund. If you provide the desired future value, I can calculate the exact value of N.
To find the value of N, we need to calculate the number of monthly deposits Sam made for his retirement fund over 20 years.
Sam deposited $1000 every month for 20 years, which is a total of 20 x 12 = 240 deposits. Each deposit has a compounded interest rate of 5% per year, compounded monthly.
The formula to calculate the future value of a series of monthly deposits is given by:
FV = P * [(1 + r)^n - 1] / r
Where:
FV is the future value of the investment,
P is the monthly deposit amount,
r is the monthly interest rate, and
n is the number of deposits.
In this case, P = $1000, r = 5% / 12 = 0.05 / 12 = 0.00417 (monthly interest rate), and FV is the value of the retirement fund after 20 years.
By rearranging the formula, we can solve for n:
n = log((FV * r) / (P * r + FV)) / log(1 + r)
Plugging in the values, we get:
n = log((FV * 0.00417) / (1000 * 0.00417 + FV)) / log(1 + 0.00417)

(5.19+4m)+(4.18+3.95m) = (4m+_)+(5.19+_)=_
Using common factor method, sum of the given expressions is 17.14m + 9.37
what is common factor ?
In mathematics, a common factor is a factor that two or more numbers have in common. For example, the numbers 12 and 18 have common factors of 1, 2, 3, and 6. The greatest common factor (GCF) is the largest number that divides evenly into two or more numbers.
In algebra, we often use the term "common factor" when referring to expressions. When two or more algebraic expressions have a factor in common, we can use the distributive property to factor out the common factor.
According to the question:
To add the expressions (5.19+4m)+(4.18+3.95m), we can first group the like terms:
(5.19 + 4.18) + (4m + 3.95m)
9.37 + 7.95m
So, the sum of the expressions is:
(5.19+4m)+(4.18+3.95m) = 9.37 + 7.95m
Now, we can use the distributive property to factor out a common factor of m from 7.95m:
9.37 + 7.95m = 4m + (5.19 + 7.95)m
We can factor out a common factor of 1 from (5.19 + 7.95)m:
4m + (5.19 + 7.95)m = (4 + 5.19 + 7.95)m
Adding the coefficients, we get:
4 + 5.19 + 7.95 = 17.14
Therefore, the sum of the expressions is:
(5.19+4m)+(4.18+3.95m) = (4m+5.19)+(3.95m+4.18)= 17.14m + 9.37.
