1. Javier is determining the exact zeros for f(x) = x2 – 14x + 19.
His work is shown.
a. Identify the error Javier made when
determining the zeros.
Answer:
The last line is
[tex]x = 7 + - \sqrt{30} [/tex]
The roots of f(x) are 7+root 30 and 7 -root 30.
We have given that the quadratic equation is
[tex]f(x)=x^2-14x+19[/tex]
We have to find the zeros of the given f(x)
Compaire the given equation with the general form of quadratic equation
What is the general form of quadratic equation?[tex]ax^2+bx+c=0[/tex]
So we get,a=1,b=-14,c=19
We find the roots by using the quadratic formula method
What is the quadratic formula ?[tex]x_{1,2}=\frac{-b\±\sqrt{b^2-4ac} }{2a}[/tex]
Use the value of a,b and c in above formula we get,
[tex]x_{1,2}=\frac{-(-14)\±\sqrt{(-14)^2-4(1)(19)} }{2(1)}[/tex]
[tex]x_{1,\:2}=\frac{-\left(-14\right)\pm \:2\sqrt{30}}{2\cdot \:1}[/tex]
[tex]x_1=\frac{-\left(-14\right)+2\sqrt{30}}{2\cdot \:1}[/tex]
[tex]=\frac{14+2\sqrt{30}}{2}[/tex]
[tex]=\frac{14+2\sqrt{30}}{2}[/tex]
[tex]=\frac{2\left(7+\sqrt{30}\right)}{2}[/tex]
[tex]=7+\sqrt{30}[/tex]
Similarly, we get,
[tex]x_2=\frac{-\left(-14\right)-2\sqrt{30}}{2\cdot \:1}[/tex]
[tex]x_2=7-\sqrt{30}[/tex]
Therefore the roots of f(x) are 7+root 30 and 7 -root 30.

How do I find the height of a pentagonal prism with just an apothem of 11cm and a side length of 9.6cm
Answer:
More details are needed
Step-by-step explanation:
Given
[tex]l = 9.6cm[/tex] --- side length
[tex]a = 11cm[/tex] --- apothem
[tex]n = 5[/tex]
Required
The height of the prism
The apothem of a prism is:
[tex]a = \frac{l}{2\tan(\frac{180}{n})}[/tex]
There are no direct links between the apothem, the height and the side lengths of a prism.
To calculate the height, we will need to the base area and the volume of the prism.
Hence, more details are needed.
1. Find the value of x.
A. 90
B. 80
C. 60
D. 45
Answer:
A 90
Step-by-step explanation:
multiple ways to prove this.
e.g. since the angle between the two lines from the center of the circle to the 2 tangent touching points is 90 degrees (that is the meaning of these 90 degrees here as the angle of the circle segment defined by the 2 tangent touching points and the circle center), the tangents have the same "behavior" as tan and cot = the tangents at the norm circle at 0 and 90 degrees. they hit each other outside of the circle again at 90 degrees.
another way
imagine the two right triangles of the tangents crossing point to the circle center and the tangent/circle touching points.
the Hypotenuse of each triangle is cutting the 90 degree angle of the circle segment exactly in half (due to the symmetry principle). so the angle between radius side and Hypotenuse is 90/2 = 45 degrees.
that means also the angle of such a right triangle at the tangent crossing point is 45 degrees (as the sum of all angles in a triangle must be 180, we have the remainder of 180 - 90 - 45 = 45 degrees).
the angles of both right triangles at that point are the same, and so we can add 45+45 = 90 degrees for the total angle at the tangent crossing point.
Y= 2x/5 -7 slope of this line?
Answer:

Step-by-step explanation:
y = (2/5)x - 7 may be compared to the standard slope-intercept equation
y = mx + b. By comparison, we find that the slope, m, is 2/5 and the y-intercept, b, is -7.

Sam and Dean are brothers. Their ages now add up to the age of their sister. In ten years, Dean's age will be the sum of their ages today. How old are each of them?
Answer:
Sam is yeas old, and Dean is (x - 10) year's old, where 'x' is the age of their sister
Step-by-step explanation:
The relationship between the ages of the brothers are;
Sam's age + Dean's age = Their sister's age
Dean's age + 10 = Dean's age + Sam's age
Therefore, we have;
Sam's age = Dean's age + 10 - Dean's age = 10
Sam's age = 10 years
Let 'x' represent their sisters age, we get;
Sam's age + Dean's age = x
10 + Dean's age = x
Dean's age (in variable form) = x - 10
What’s the equation for X?
Answer:
perimeter of rectangles = 2 ( l + b)
34 = 2 ( x + 2 + 3x - 4 )
34 = 2 ( 4x - 2 )
34 = 8x - 4
38 = 8 x
38/ 8 = x
thus , x = 4.75 inches
Answer:
x=19/4
Step-by-step explanation:
perimeter is the sum of all sides
so
perimeter given is 34 = (x+2)+(x+2)+(3x-4)+(3x-4)
34=8x-4
34=8x
x=34/8 which reduces to 19/4
Tristan records the number of customers who visit the store each hour on a Saturday. His data representing the first seven hours are 15, 23, 12, 28, 20, 18, and 23. How many customers visited the store during the eighth hour if the median number of customers per hour did not change?
16
19
20
23
Answer:
20
Step-by-step explanation:
The number of Customers that visited the store during the eight hour if the median number of customers didn't change is; C: 20
What is the Median?We are given the data representing the first seven hours as; 12, 15, 18, 20, 23, 23, 28. Here; n=7
Thus;
Median = (n + 1)/2 = (7 + 1)/2
Median = 4th term
Thus, the median is 20.
When one data is added, n = 8. Thus;
Median will be the average of the 4th and 5th term. Since the median does not change, it means that the median number of customers per hour is still 20.

Answer:
It should be self-explanatory if you look at the numbers#1
P(green or red) = (5 + 6)/(5 + 7 + 6) = 11/18 or 61.11%#2
P(grape or banana) = (6 + 11)/(6 + 11 + 13) = 17/30 or 56.67%Answer:
1.) P( green or red ) = 11 /18
2.) P ( grapes and bnaa ) = 17 / 30
Step-by-step explanation:
1 .) Probability of boy picking a green or red bior closing his eyes
= sum of red and green biros / Total no. of biros in a packet.= 5 + 6 / 5 + 7 + 6
P( green or red ) = 11 /18
2.) Probability of that the fruit is either a grape and banana , P ( grapes and banana)
= Sum of grapes and banana / total no. of fruits in basket.P ( grapes and banana ) = 6 + 11 /6 +11 +13

Which r-value represents the most moderate correlation?
–0.92
–0.18
0.56
0.83
Answer:
0.56
Step-by-step explanation:
The r-value that represents the most moderate correlation is 0.56
How to determine the moderate correlation value?Correlation is represented with r.
And the range of values of r is:
-1 ≤ r ≤ 1
This means that r can take any value from -1 to 1
-1 and 1 are considered strong correlation
While values closer to 0.5 or - 0.5 are moderate
From the list of options,
0.56 is closer to 0.5 than others
Hence, the r-value that represents the most moderate correlation is 0.56

What does f(10) represent?
The number of dollars it costs for 10 people to rent the house
The number of houses that can be rented for 10 days
The number of days the house can be rented for a cost of $250
The number of dollars it costs to rent the house for 10 days
Answer:
260 of dollars it costs to rent the house for 10 days
The number of dollars it costs to rent the house for 10 days
Step-by-step explanation:
F(x) = 10 + 25x
F(10) = 10 + 25*(10)
F(10) = 10 + 250
F(10) = 260 of dollars it costs to rent the house for 10 days
Here f (10) represent 260 of dollars it costs to rent the house for 10 days
Given that,
The equation is f(x) = 10 + 250x.
Based on the above information, the calculation is as follows:
F(x) = 10 + 25x
= 10 + 25(10)
= 10 + 250
= 260 of dollars it costs to rent the house for 10 days

12. An item was sold at a loss of 20%. Had it been sold for Rs. 50
more then, the profit would have been 5%. What is the cost
price of the item?
Given:
An item was sold at a loss of 20%.
If the item is sol for Rs. 50 more then, the profit would have been 5%.
To find:
The cost price of the item.
Solution:
Let x be the cost price of the item.
The item was sold at a loss of 20%. Then selling selling price is:
[tex]S.P.=x-\dfrac{20}{100}x[/tex]
[tex]S.P.=x-0.2x[/tex]
[tex]S.P.=0.8x[/tex]
If a the item is sold for 5% profit, then the selling price is:
[tex]S.P.=x+\dfrac{5}{100}x[/tex]
[tex]S.P.=x+0.05x[/tex]
[tex]S.P.=1.05x[/tex]
It is given that, if the item is sol for Rs. 50 more then, the profit would have been 5%. So,
[tex]0.8x+50=1.05x[/tex]
[tex]50=1.05x-0.8x[/tex]
[tex]50=0.25x[/tex]
Divide both sides by 0.25.
[tex]\dfrac{50}{0.25}=x[/tex]
[tex]200=x[/tex]
Therefore, the cost price of the item is Rs. 200.
Write the equation of the line that has a slope of -4 and passes through the point (-2,-5).
Answer:
B
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 4 , then
y = - 4x + c ← is the partial equation
To find c substitute (- 2, - 5) into the partial equation
- 5 = 8 + c ⇒ c = - 5 - 8 = - 13
y = - 4x - 13 → B
