Answer:
f(x) = (x + 1)(x - 4)
Step-by-step explanation:
let f be the function
FACTORED FORM of f :
f(x) = a(x - p)(x - q)
Where p and q are the roots/zeros of f
and ‘a’ is a real number.
=================================
Find p and q :
The roots of f are the x-coordinates where the graph crosses the x-axis, which can be read from the graph: x = -1 and x = 4 ⇒ p = -1 and q = 4.
then f(x) = a(x + 1)(x - 4)
Find ‘a’ :
f(3) = -4 ⇒ a((3) + 1)((3) - 4) = -4 ⇒ a(4)(-1) = -4 ⇒ -4a = -4 ⇒ a = 1
Therefore, f(x) = (x + 1)(x - 4)

The selling price of an item is $720. It is marked down by 30%, but this sale price is still marked up from the cost of $420. Find the markup from cost to sale price.
Answers
The markup cost is $84 if the selling price of an item is $720. It is marked down by 30%, but this sale price is still marked up from the cost of $420.
What is markup price?Markup pricing is the practice in which the price of products or commodity is determined by taking all the goods together and adds a fraction as a markup.
We have:
The selling price of an item is $720. It is marked down by 30%
[tex]\rm = 720\times \dfrac{30}{100}[/tex]
Markdown = 216
Now subtract it from the selling price:
= 720-216
Sale price = 504
Now,
= 504-420
Markup cost = $84
Thus, the markup cost is $84 if the selling price of an item is $720. It is marked down by 30%, but this sale price is still marked up from the cost of $420.

The diameter of a circle is 26 cm. Find its area to the nearest whole number.
Answers
= pi x 13^2
=pi x 169
= 530.929
= to the nearest whole number 531
Answer:
531
Step-by-step explanation:
The area of a circle can be determined by the equation: A = πr².
The "r-value" represents the radius, which is half of the diameter. Since the diameter is in cm, the area will have the unit cm².
d = diameter r = radius π = 3.14..... A = area
d / 2 = r
26 / 2 = r
13 cm = r
A = πr²
A = π(13)²
A = 169π
A = 530.929.... cm²
A = 531 cm²
As you can see, the radius was determined to be 13 cm. When you plug that value into the area equation, you get 530.9 cm². Rounding to the nearest whole number would bump the 0 to 1, making the final answer 531 cm².
If data is normally distributed and has μ = 90 and o-10, what is the z-score for a data value of 75?
Answers
Answer:
The z-score for this data is -1.5
Step-by-step explanation:
Step 1: For the specified distribution and data point,
μ = 90, σ = 10, and x = 75 (given)
Step 2: We now apply the z-score formula:
z = x − μ / σ
z = 75 - 90 / 10
z = - 15 / 10
z = -1.5
We can take it a step further:
A z-score table shows the percentage of values (usually a decimal figure) to the left of a given z-score on a standard normal distribution
percentage of value = 0.0668

What does 18x12x1000 equal to?
Answers
Because 1000 has 3 zeros, add 3 zeros after 216. Answer is 216,000
First, we calculate 18 x 12
18 x 12 = 216.
To multiply a number by 1000, we add 3 zeros after it.
So, 216 x 1000 = 216000
-> 18 x 12 x 1000 = 216000.
