Answer:
b = 2, c = - 8
Step-by-step explanation:
Given x = a is a root then (x - a) is a factor
Here the roots are x = - 4 and x = 2 , then the corresponding factors are
(x + 4) and (x - 2)
The equation is then the product of the factors , that is
(x + 4)(x - 2) = 0 ← expand factors using FOIL
x² + 2x - 8 = 0
with b = 2 and c = - 8
8 is 4% of the number
Answer:
(8/4)100 = 200
Step-by-step explanation:
Simplify the following:
8/4×100
Hint: | Express 8/4×100 as a single fraction.
8/4×100 = (8×100)/4:
(8×100)/4
Hint: | In (8×100)/4, divide 100 in the numerator by 4 in the denominator.
4 | | 2 | 5
| 1 | 0 | 0
- | | 8 |
| | 2 | 0
| - | 2 | 0
| | | 0:
8×25
Hint: | Multiply 8 and 25 together.
8×25 = 200:
Answer: 200
I believe that the answer is 200

Solve the right triangle. Round your answers to the nearest tenth.
Answer:
A=42 degrees a=13.5 c=20.2
Step-by-step explanation:
Knowing that all the angles in a triangle add up to 180, we simply subtract 90 and 48 from 180 to figure out angle A.
For side a and c we can us trig to figure them out. Sin is equal to opposite over hypotenuse so the sin(48)=15/c, rearranging this equation we can do 15/sin(48)=c to figure out the length of side c
For a we use tan, which is opposite over adjacent. So we can make the formula tan(48)=15/a then rearrange this to 15/tan(48)=a to figure out the length of a

Suppose you know the minimum, lower quartile, median, upper quartile, and maximum values for a set of data. Explain how to create a box plot for the data set.
NO LiNKS OR BE REPORTED
Answer:
For some sets of data, some of the largest value, smallest value
, first quartile, median, and third quartile may be the same. For instance, you might have a data set in which the median and the third quartile are the same. In this case, the diagram would not have a dotted line inside the box displaying the median. The right side of the box would display both the third quartile and the median. For example, if the smallest value and the first quartile were both one, the median and the third quartile were both five, and the largest value was seven, the box plot would look like:
In this case, at least
25
25
% of the values are equal to one. Twenty-five percent of the values are between one and five, inclusive. At least
25
25
% of the values are equal to five. The top
25
25
% of the values fall between five and seven, inclusive.
Answer:
First, create a scale that includes all the numbers- that being, you can plot both the minimum and maximum values on it.
Next, draw a line of a set height (I tend to use 2 squares in my work) where the median is. Next, draw similar lines, at the same height, for the rest of the values- both quartiles and the maximum values. You can obviously do this in whatever order you like, but that's how I do it.
Next, join up the tops and bottoms of the quartiles, with the median in the middle, and connect the middles of the quartiles to their corresponding minimum or maximum values.
Voila, my friend. You have a box plot.

Business owners use percents to calculate markup, discount, and sales tax. A shoe store owner buys a pair of shoes for $20. There is a sale on the item for 20% off.
Answer:
$16
Step-by-step explanation:
Given data
The cost price of the shoe= $20
Discount = 20%
Let us find the amount of the 20% discount
=20/100*20
=0.2*20
=$4
Hence the selling price will be
=20-4
=$16

The percentage increase in wages of from last year to now is 7.5%.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given that, last year janes wages were $80 per week her wages are now $86 per week.
Now, the difference in wage =86-80
= 6
The percentage increase
= 6/80 ×100
= 7.5%
Therefore, the percentage increase in wages of from last year to now is 7.5%.

What is AC? Please help me with this problem fast
Answer:
37
Step-by-step explanation:
Pythagorean theorem
Answer: 37 (side AB)
Step-by-step explanation:
For this question you would have to use Pythagoras' theorem. Pythagoras' theorem states that c²=a²+b².
so when you put the numbers in the formula you get c²=12²+35²
12²=144
35²=1225
c²=144+1225
c²=1369
Then because you want c on it's own you square root 1369.
c=√1369
c=37

A company sells widgets. The amount of profit, y, made by the company, is related to the selling price of each widget, x, by the given equation. Using this equation, find out what price the widgets should be sold for, to the nearest cent, for the company to make the maximum profit.
y=-x^2+73x-520
y=−x
2
+73x−520
Answer:
36.5
Step-by-step explanation:
y= -x²+73x-520
which can be represented as ax²+bx+c
a= -1, b= 73, c = -520
for maximum value of y,
the formula is
c - (b² / 4a)
= -520 - (73² / 4×(-1))
= -520 - (5329 / -4)
= -520 + 1332.25
= 812.25
Solving for x,
812.25 = -x²+73x-520
or, x²-73x+ 1332.25 = 0
Solving,
x= 36.5
