100 POINTS!!!!!!!!!!!!!!!!!!!!!!!!!!! PLEASE SHOW STEPS TO ALL PARTS
Use the function f(x) to answer the questions:
f(x) = 4x2 − 7x − 15
Part A: What are the x-intercepts of the graph of f(x)? Show your work. (2 points)
Part B: Is the vertex of the graph of f(x) going to be a maximum or a minimum? What are the coordinates of the vertex? Justify your answers and show your work. (3 points)
Part C: What are the steps you would use to graph f(x)? Justify that you can use the answers obtained in Part A and Part B to draw the graph. (5 points)
Answer:
Part A & B
Step-by-step explanatPart A:
f(x) = 4x ^ 2 - 7x - 15
0 = 4x ^ 2 - 7x - 15
a = 4, b = -7, c = -15
a x c = -60
-12 x 5 = -60
-12 + 5 = -7
(4x + 5)(4x - 12)
4x ^ 2 - 12x I + 5x - 15
4x(x - 3) + 5(x - 3)
(x - 3)(4x + 5)
x = 3 x = -1.25 or -5/4
Part B:
Minimum point
(x1 + x2)/2
(3 -1.25)/2 = 0.875
f(x) = 4x ^ 2 - 7x - 15
f(0.875) = 4(0.875) ^ 2 - 7(0.875) - 15
f(0.875) = 3.06 - 6.125 - 15
f(0.875) = -18.065ion:

A. (3,-5)
B. (-5,3)
C. (3,5)
D. (-5, -3)
Your answer is A!
Step-by-step explanation:
Your answer is A!
The coordinate point from the given graph is (3, -5). Therefore, option A is the correct answer.
What is coordinate plane?A coordinate plane is a two-dimensional surface formed by two number lines. It is formed when a horizontal line (the X-axis) and a vertical line (the Y-axis) intersect at a point called the origin. The numbers on a coordinate grid are used to locate points.
From the given coordinate plane, the coordinate point lies in fourth quadrant.
Where, x-coordinate is positive and y-coordinate is is negative.
The coordinate point correspond to x-axis is 3 and coordinate point correspond to y-axis is 5.
So, the coordinate point is (3, -5)
Therefore, option A is the correct answer.

A right angled triangular prism has length 3m, breadth 2m and height 2.5m. If the mass of the prism is 3.4kg, find its density
Answer:
The density of the prism is 0.453 kilograms per cubic meter.
Step-by-step explanation:
Let suppose that mass in the prism is uniformly distributed. Then, the definition of density ([tex]\rho[/tex]), in kilograms per cubic meter, is defined by the equation below:
[tex]\rho = \frac{m}{V}[/tex] (1)
Where:
[tex]m[/tex] - Mass, in kilograms.
[tex]V[/tex] - Volume of the right angle triangle prism, in cubic meters.
Besides, the volume of the right angle triangle prism is:
[tex]V = \frac{1}{2}\cdot b\cdot h\cdot l[/tex] (2)
Where:
[tex]b[/tex] - Breadth of the base, in meters.
[tex]h[/tex] - Height of the base, in meters.
[tex]l[/tex] - Length of the base, in meters.
If we know that [tex]b = 2\,m[/tex], [tex]h = 2.5\,m[/tex], [tex]l = 3\,m[/tex] and [tex]m = 3.4\,kg[/tex], then the density of the prism is:
[tex]V = 7.5\,m^{3}[/tex]
[tex]\rho = 0.453\,\frac{kg}{m^{3}}[/tex]
The density of the prism is 0.453 kilograms per cubic meter.

Mei runs 60.36 miles in 4 weeks. If she runs 3 days each week, what is the average distance she runs each day?
Answer:
15.09
Step-by-step explanation:
She ran only 12 times every 4 weeks, so we divide 60.36 by 4 which then becomes the result of running 3 days a week which means the answer is 15.09 because 15.09 multiplied by 4 is 60.36.
Answer:
The answer is 15.09.

If AC = 30 and AE = 3x + 3, then x = ________.
If DC = 6x + 1, BC = 2y + 2, AB = 25, and AD = 14, then x = _______ and y = _______.
Answer and Step-by-step explanation:
Part 1:
AE is equal to EC
3x + 3 + 3x + 3 = 30
6x = 24
x = 4
DC is equal to AB
6x + 1 = 25
6x = 24
x = 4
BC is equal to AD
2y + 2 = 14
2y = 12
y = 6

What is the approximate area of a circle with the diameter of 20cm in square centimeters (use 3.14 for pie(
Answer:
314cm
Step-by-step explanation:
the area formular for a circle is a=pi(r)^2. Using this information we can plug in the numbers...
3.14(10)^2. Next square 10 to get 3.14*100. Then you get 314 which is the answer. The reason I used 10 is because the diameter is half of the radius so half of 20 would be 10.
A roll of tape has a circumference of 14.8 centimeters. The circumference decreases 2.4 centimeters after you use some of the tape. What is the diameter of the roll after you use the tape? ROUND to the nearest HUNDREDTH. I need answers quick
Answer:
7.900 cm
Step-by-step explanation:
The computation of the diameter after using the tape is given below:
Since the circumference is 14.8 cm
And it would be decrease by 2.4 cm
So, the new circumference is
= 14.8 - 2.4
= 12.4 cm
Now the radius is
= 12.4 ÷ π
= 3.95
And, the diameter is
= 3.95 × 2
= 7.900 cm

A new business borrows $320,000 at a yearly simple interest rate of 7%. The total amount the
company repays for the loan and interest is $678,400. How long did it take to pay off the loan?
Answer:
16 years
Step-by-step explanation:
Annual interest payment is 7% * 320k = 22,400
Total interest is 678400-320000=358400
358400/22400=16
The number of years that it takes to pay off the loan will be 16 years.
What is simple interest?Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on.
The formula for interest is written as,
I = (PRT)/100
Where P is the principal, R is the rate of interest, and T is the time.
A new business borrows $320,000 at a yearly simple interest rate of 7%. The total amount the company repays for the loan and interest is $678,400. Then the equation is given as,
P + I = A
$320,000 + ($320,000 x 7 x T) / 100 = $678,400
$22,400 T = $358,400
T = 16 years
The number of years that it takes to pay off the loan will be 16 years.
