What are the values of d, e, and f?
Answers
Answer:
B
Step-by-step explanation:
The given equation y = 2x^2 -12x - 32 can be factored as follows:
y = 2(x^2 - 6x - 16) = 2(x - 8)(x + 2). Then its roots are x = -2 and x = 8.
Since d > e and 8 > -2, we conclude that d = 8 and e = -2.
We need to find the minimum of y = 2x^2 -12x - 32.
We can do this by finding the vertex: b
The equation of the axis of symmetry is x = - ----------
2a
-12
which here is x = - --------- = 3

so f = 3.

which equation in slope intercept form contains the point (4, -1) and has a slope of 3
Answers
Answer:
Final answer is [tex]y=3x-13[/tex].
Step-by-step explanation:
Given that slope of the line is m=3
Plug the given point (4,-1) and the slope m=3 into point sloep formula:
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-(-1)=3\left(x-4\right)[/tex]
[tex]y+1=3\left(x-4\right)[/tex]
[tex]y+1=3x-12[/tex]
[tex]y=3x-12-1[/tex]
[tex]y=3x-13[/tex]
Which looks like slope intercept form of line y=mx+b
Hence final answer is [tex]y=3x-13[/tex].
The answer is:
The equation in slope-intercept form is:
[tex]y=3x-13[/tex]
Why?To solve the problem and find equation in slope-intercept form of the line, we need to use the following formula:
[tex]y=mx+b[/tex]
We are given the slope of the line, so, rewriting we have:
[tex]y=3x+b[/tex]
Then, to find "b" we need to substitute the given point into the equation, so, substituting we have:
[tex]y=mx+b[/tex]
[tex]-1=3*(4)+b[/tex]
[tex]-1=12+b[/tex]
[tex]b=-1-12=-13[/tex]
Therefore, writing the equation of the line, we have:
[tex]y=3x-13[/tex]

Answers
Answer: y=31
Step-by-step explanation
If x=5 and y=6x+1, you plug in 5 for x in the equation y=6x+1.
This would cause it to be y=6(5)+1.
Then you multiply 6*5, which equals 30. thatll turn into y=30+1
30+1=31, so y=31
Answer:
Y = 31
Step-by-step explanation:
Replace x with 5
Y = (6*5) + 1
Use PEMDAS
Parentheses
Exponent
Multiplication
Division
Subtraction
Addition
6 * 5 = 30
Y = 30 + 1
30 + 1 = 31
Y = 31

What are Trigonometric ratios?Trigonometric ratios are the ratios of the length of sides of a triangle.
In trigonometry, there are six trigonometric ratios, namely, sine, cosine, tangent, secant, cosecant, and cotangent.
We know that,
According to the trigonometric table the value of cos 90° is 0.
i.e., cos 90°.
This is because there is no horizontal component of the angle: The horizontal component of the angle is 0, so, the cosine of 90° is 0.
In other words,
the cosine of an angle tells the size of the adjacent side of a right triangle compared to the hypotenuse. Look at the unit circle to see why the adjacent side (the x axis) has a width of 0 when the angle between the initial arm and the terminal arm is a right angle.
Thus, value of cos 90 is 0.

Where mBD =70° and mCA = 170°
Answers
Answer:
m∠BPD = 120
mBC + mAD = 120°
Step-by-step explanation:
according to intersecting chord theorem: The measure of the angle formed by two chords that intersect inside the circle is [tex]\frac{1}{2}[/tex] the sum of the chords' intercepted arcs.
m∠BPD = [tex]\frac{1}{2}[/tex] (M∠BD + M∠CA)
= [tex]\frac{1}{2}[/tex] (70 + 170)
= [tex]\frac{1}{2}[/tex] (240)
m∠BPD = 120
We know that a circle has a total of 360° around the center of circle. To find the measure of the remaining measure of angle of arcs, subtract them from the whole that is 360°
mBC + mAD = 360 - ( 70 + 170 )
= 360 - 240
mBC + mAD = 120°

A basketball is thrown upwards. The height f(t), in feet, of the basketball at time t, in seconds, is given by the following function:
f(t) = −16t2 + 16t + 32
Which of the following is a reasonable domain of the graph of the function when the basketball falls from its maximum height to the ground?
0.5 < t < 1
0.5 < t < 2
1 < t < 2
1 < t < 1.5
Answers
Answer:
0.5 < t < 2
Step-by-step explanation:
The function reaches its maximum height at ...
t = -b/(2a) = -16/(2(-16)) = 1/2 . . . . . . where a=-16, b=16, c=32 are the coefficients of f(t)
The function can be factored to find the zeros.
f(t) = -16(t^2 -1 -2) = -16(t -2)(t +1)
The factors are zero for ...
x = -1 and x = +2
The ball is falling from its maximum height during the period (0.5, 2), so that is a reasonable domain if you're only interested in the period when the ball is falling.
What is the vertex of the quadratic function f(x) = (x – 6)(x + 2)?
Answers
Answer:
The vertex is (2,-16)
Step-by-step explanation:
The given function is [tex]f(x)=(x-6)(x+2)[/tex]
We expand to obtain;
[tex]f(x)=x^2+2x-6x-12[/tex]
[tex]f(x)=x^2-4x-12[/tex]
We complete the squares to obtain;
[tex]f(x)=x^2-4x+(-2)^2-12-(-2)^2[/tex]
[tex]f(x)=x^2-4x+(-2)^2-12-4[/tex]
[tex]f(x)=(x-2)^2-16[/tex]
The vertex form is [tex]f(x)=(x-2)^2-16[/tex]
Comparing this to
[tex]f(x)=a(x-k)^2+k[/tex]
The vertex is (h,k)= (2,-16)
Final answer:
The vertex of the quadratic function f(x) = (x - 6)(x + 2) is found by expressing the function in vertex form. After completing the square, the vertex of the function is determined to be at the point (2, -16).
Explanation:
To find the vertex of the quadratic function f(x) = (x
– 6)(x + 2), we first need to express the function in vertex form, which is y = a(x - h)² + k, where (h, k) is the vertex of the parabola. Multiplying out the factors gives us f(x) = x² - 4x - 12. Completing the square allows us to transform this equation into vertex form.
First, Factor out the leading coefficient (which is 1 in this case, so this step is not needed), and then rewrite the function isolating the terms with x:
f(x) = x² - 4x + ____ - 12 + ____.
We complete the square by finding the value that makes x² - 4x + ____ a perfect square trinomial. This value is (-4/2)² = 4, so we add and subtract 4 inside the function:
f(x) = x² - 4x + 4 - 12 - 4.
Now we have f(x) = (x - 2)² - 16. Thus, the vertex form of the function is y = (x - 2)² - 16, and the vertex of the parabola is at the point (2, -16).

The graph shows which inequality? The vertex is (-1,3)
Answers
Answer: Last Option
[tex]y> | x + 1 | +3[/tex]
Step-by-step explanation:
First we must identify the function shown in the graph.
It is a function of absolute value whose vertex is in the point (-1, 3)
The absolute value parent function is:
[tex]h(x) = | x |[/tex]. And it has its vertex in (0, 0)
The function shown in the graph is the function h(x) displaced 1 unit to the left and 3 units to the top.
Therefore the function shown in the graph [tex]f(x) = h (x + 1) +3[/tex]
[tex]f (x) = | x + 1 | +3[/tex].
Then, the region shaded in the graph are all the values of y that are above the graph of [tex]f (x) = | x + 1 | +3[/tex]
That is, the region is formed by all values where y is greater than [tex]f (x) = | x + 1 | +3[/tex]
Then the inequality is:
[tex]y> | x + 1 | +3[/tex]

Shawna can paint a fence in 8 hours. Kevin can paint the same fence in 4 hours. How long will it take them working together? Show all work.
Answers
Answer: 2.66 hours
Step-by-step explanation:
Shawana can paint a fence in 8hours which means in one hour she can paint 1/8 of a fence.
Kevin can paint the same fence in 4 hours, so in one hour he can paint 1/4 of the fence.
Together in 1 hour they can paint 1/8 + 1/4 = 3/8
Total hours for painting is 3/8 or 2.66 hours
The answer is:
The will paint the same fence at the same time in 2.67 hours.
Why?From the statement we know that Shawna can paint a fence in 8 hours while Kevin can paint the same in 4 hours, and we are asked to calculate how long will it take them to paint the fence working together, so, calculating we have:
For Shawna, we have:
[tex]ShawnaRate=\frac{FencePainted}{TimeToPaint}\\\\ShawnaRate=\frac{1fence}{8hours}[/tex]
For Kevin, we have:
[tex]KevinRate=\frac{FencePainted}{TimeToPaint}\\\\KevinRate=\frac{1fence}{4hours}[/tex]
So, the combined work for both Shawna and Kevin will be:
[tex]CombinedWorkRate=\frac{1fence}{8hours} +\frac{1fence}{4hours}\\\\CombinedWorkRate=\frac{4fence.hours+8fence.hours}{32hours^{2}}\\ \\CombinedWorkRate=\frac{12fence.hours}{32hours^{2}}\\\\CombinedWorkRate=\frac{12fence.hours}{32hours^{2}}=\frac{3fence}{8hours}[/tex]
Now, if the want to paint the same fence at the same time, we can calculate it by the following way:
[tex]\frac{3fence}{8hours}=\frac{1fence}{x(hours)}\\\\x=1fence*\frac{8hours}{3fence}=2.67hours[/tex]
Hence, the will paint the same fence at the same time in 2.67 hours.
