Answer:
(x - 1) and (x + 4)
Step-by-step explanation:
Given the zeros of a polynomial, say x = a, x = b then the factors are
(x - a), (x - b) and the polynomial is the product of the factors, that is
f(x) = (x - a)(x - b)
Here the zeros are x = 1 and x = - 4, thus the factors are
(x - 1) and (x - (- 4)), that is (x - 1) and (x + 4)
Blake drew a circle with a circumference of 37.68 cm. What is the diameter of that circle?
Given Information:
Circumference of circle = C = 37.68 cm
Required Information:
Diameter of circle = D = ?
Answer:
Diameter of circle = [tex]D = 11.99[/tex] [tex]cm[/tex]
Step-by-step explanation:
We know that circumference of a circle is given by
[tex]C=2\pi r[/tex]
Where r is the radius of circle.
The relation between radius and diameter is given by
[tex]r = \frac{D}{2}[/tex]
Substitute r into above equation of circumference.
[tex]C=2\pi (\frac{D}{2} )[/tex]
[tex]C=\pi D[/tex]
[tex]D = \frac{C}{\pi}[/tex]
[tex]D = \frac{37.68}{\pi}[/tex]
[tex]D = 11.99[/tex] [tex]cm[/tex]

Answer:
79/9 * pi
Step-by-step explanation:
First find the circumference of the entire circle
C = 2 pi r
C = 2* pi* 5
C = 10 pi
The degree of MPN is 360 - 44 = 316
The fraction of the circle is 316/360 =79/90
Multiply that by the total circumference
79/90 * 10 pi
79/9 * pi
Answer:
s = 11π/9 units
Step-by-step explanation:
The arc length formula is s = rФ, where Ф is the central angle in radians.
Here the central angle is given as 44° and must be converted to radians:
44° π
------ * ----- = 11π/45 radians
1 180°
The length of arc MAN (not MPN) is s = (5 units)(11π/45 radians), or
s = 11π/9 units
An employee has a starting salary of $20,000 and can choose from two salary options:
Option 1: A salary increase by 5% each year.
Option 2: A guaranteed increase of $1,000 each year.
i. Which option is initially more beneficial?
ii. Which option is more beneficial after 10 years of employment?
iii. Explain your reasoning
Initially, both salary options provide the same increase, but after two years Option 1 becomes more beneficial due to compounding. After 10 years, the 5% annual increase of Option 1 provides a higher salary than the flat rate increase of Option 2.
Explanation:The salary options present themselves differently over time. Initially, Option 2, the guaranteed increase of $1,000 each year, is more beneficial. In the first year, a 5% increase on a $20,000 salary (Option 1) is only $1,000 - the same as Option 2. However, in the second year, the 5% increase is applied to the new salary of $21,000 (in Option 1), which gives an increase of $1,050 - thus, it surpasses Option 2.
After 10 years, Option 1 will be more beneficial. The reason lies in the principles of compounding; each year, the 5% increase is applied to the increased salary. Thus, in 10 years' time, the amount gained annually in Option 1 significantly surpasses the static $1,000 per year increase of Option 2.

At a Noodles & Company restaurant, the probability that a customer will order a nonalcoholic beverage is .51.
Find the probability that in a sample of 10 customers, at least 7 will order a nonalcoholic beverage.
Answer:
[tex]P(x\geq 7)=0.1886[/tex]
Step-by-step explanation:
The variable x, that said the number of customer that will order a nonalcoholic beverage in a sample of n customers follows a binomial distribution. Because we have n identical and independent events with a probability p of success and (1-p) of fail.
So, the probability that x customers will order a nonalcoholic beverage is:
[tex]P(x)=\frac{n!}{x!(n-x)!}*p^{x}*(1-p)^{n-x}[/tex]
Where n is the size of the sample and p is the probability that a customer order a nonalcoholic beverage, so replacing the values, we get:
[tex]P(x)=\frac{10!}{x!(10-x)!}*0.51^{x}*(1-0.51)^{10-x}[/tex]
Now, the probability that at least 7 will order a nonalcoholic beverage is equal to:
[tex]P(x\geq 7)=P(7)+P(8)+P(9)+P(10)[/tex]
Where:
[tex]P(7)=\frac{10!}{7!(10-7)!}*0.51^{7}*(1-0.51)^{10-7}=0.1267\\P(8)=\frac{10!}{8!(10-8)!}*0.51^{8}*(1-0.51)^{10-8}=0.0494\\P(9)=\frac{10!}{9!(10-9)!}*0.51^{9}*(1-0.51)^{10-9}=0.0114\\P(10)=\frac{10!}{10!(10-10)!}*0.51^{10}*(1-0.51)^{10-10}=0.0011[/tex]
So, [tex]P(x\geq 7)[/tex] is equal to:
[tex]P(x\geq 7)=0.1267+0.0494+0.0114+0.0011\\P(x\geq 7)=0.1886[/tex]
Finally, the probability that in a sample of 10 customers, at least 7 will order a nonalcoholic beverage is equal to 0.1886
El perímetro del cuadrado ABCD es 24cm. Halla la medida de
forma simple:
Answer:
Sides: 6 cms
Diagonal: 8.49 cms
Step-by-step explanation:
In a square the possible measurements to calculate are its sides and its diagonal, therefore we calculate both:
The perimeter of a square is calculated as the sum of its four sides. This is defined as a figure that has four equal sides, then:
4/24 = 6
Therefore each side measures 6 cm.
For the diagonal, we use pythagoras since it corresponds to the hypotenuse of a right triangle that is formed by drawing the diagonal:
c ^ 2 = a ^ 2 + b ^ 2
c ^ 2 = 6 ^ 2 + 6 ^ 2
c ^ 2 = 36 + 36 = 72
c = 72 ^ (1/2)
c = 8.49
What the diagonal means is 8.49 cm.
Divide.

The area of the polygon is 48 mi2. What is the length of side a? miles
To find the Length of Polygon Sides ('a') of a square polygon with an area of 48 mi², we apply the formula a = √Area. This gives a = √48 miles. This formula applies specifically to squares.
Given the area of the polygon is 48 square miles, to find the length of a side, we would first need to know the type of polygon.
For instance, if it's a square, the area is calculated by squaring one of its sides (Area = side²).
Here, to find the side length ('a'), we take the square root of the area. So, a = √Area.
Applying this to the given area, a = √48 miles.
However, please note that this formula is for a square.
Other polygons have different formulas for calculating such dimensions.

What is the value of u? (Geometry problem)
Answer:
U = 71 degrees
Step-by-step explanation:
First you should set up an equation:
180 = b + (b - 19) + (180 - (b + 45))
Since there are 180 degrees in a triangle, set the sum of the angles equal to 180. And, since (u) and (b + 45) are supplementary angles that add up to 180, you can substitute (180 - (b + 45)) for (u).
Then, solve for (b):
180 = b + b - 19 + 180 - b - 45
180 = b + 116
64 = b
Find (b + 45):
64 + 45 = 109
Solve for (u):
180 - 109 = 71
u = 71

PHP (If needed, round answer to 2 decimal places.)
Answer:
k = 35.57624,903.20 PHPStep-by-step explanation:
We want k such that ...
PHP = k·USD
Then the value of k is ...
PHP/USD = k = 12,451.60/350
k = 35.576
__
700 USD will convert to twice as much as 350 USD, so ...
700 USD = 700·35.576 PHP = 24,903.20 PHP
The constant of proportionality is 35.58. When you have 700 USD to convert, you will receive 24906.00 PHP.
Explanation:To find the constant of proportionality, we can use the formula:
k = y / x, where k is the constant of proportionality, y is the dependent variable (number of Philippine Pesos received), and x is the independent variable (number of US Dollars).
In this case, we have:
k = 12451.60 / 350 = 35.58 (rounded to 3 decimal places)
Now, to find the amount of PHP given 700 USD to convert, we can use the same formula:
