Answer:
2([tex]x^{2}[/tex]+8x+17)
Step-by-step explanation:
Factor out 2 of the equation.
Answer:
For real numbers: no solution
For complex numbers: [tex] x = -4 \pm 4i [/tex]
Step-by-step explanation:
2x^2 + 16x + 34 = 0
Divide both sides by 2.
x^2 + 8x + 17 = 0
There are no two numbers whose product is 17 and whose sum is 8, so this polynomial is not factorable.
We can use the quadratic formula.
[tex] x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a} [/tex]
We have a = 1; b = 8; c = 17
[tex] x = \dfrac{-8 \pm \sqrt{8^2 - 4(1)(17)}}{2(1)} [/tex]
[tex] x = \dfrac{-8 \pm \sqrt{64 - 68}}{2} [/tex]
[tex] x = \dfrac{-8 \pm \sqrt{-64}}{2} [/tex]
If you have not learned imaginary or complex numbers, stop here. Since the discriminant is negative, there is no real solution.
If you have learned complex numbers, then we continue.
[tex] x = \dfrac{-8 \pm 8i}{2} [/tex]
[tex] x = -4 \pm 4i [/tex]
For the function f(x) = – 3x + 8, determine f(-5)
Answer:
23
Step-by-step explanation:
f(x) = – 3x + 8
Let x = -5
f(-5) = – 3*-5 + 8,
= 15 +8
= 23
Answer:
f(-5) = 23
Step-by-step explanation:
plug in -5 for x
f(-5) = -3(-5) + 8
-3 x -5 = 15.
15 + 8 = 23
f(-5) = 23
J is between H and K. If HJ = 4t - 15, JK = 5t - 6, and KH = 15, find JK
Answer:
JK = 14
Step-by-step explanation:
Since, J is between H and K.
Therefore,
HJ + JK = KH
4t - 15 + 5t - 6 = 15
4t + 5t - 15 - 6 = 15
9t - 21 = 15
9t = 15 + 21
9t = 36
t = 36/9
t = 4
JK = 5t - 6 = 5*4 - 6 = 20 - 6 = 14
A surveyor is surveying a street. The surveyor is standing at point C looking down the street at no parking sign at point D and a stop sign at point R. Given CD = 6x-8 meters, DR = 4 meters, and point D is between C and R, what is x in meters?
Answer:
2Step-by-step explanation:
If point D is between C and R, then the vector CD = DR is true. Given the following parameter CD = 6x-8 meters, DR = 4 meters, to get the value of X we will equate both vector functions as shown;
6x-8 = 4
add 8 to both sides
6x-8+8 = 4+8
6x = 12
divide both sides by 6
6x/6 = 12/6
x = 2
Hence the value of x in metres is 2 metres.

What is the 3rd term of the linear sequence below? 22 18, 14, 10, 6
Answer:
As we can see, what we are doing is substracting 4 from one term to the next:
22 - 4 = 18
18 - 4 = 14
14 - 4 = 10
10 - 4 = 6
Knowing this and that we start on 22, we can say that for n term we have:
[tex]22-4(n-1)[/tex]
So, if we're searching the thirs term, we replace n by 3 (we can also see it in the question):
[tex]22-4(n-1)[/tex] = [tex]22-4(3-1) = 22-4*2 = 22 - 8 = 14[/tex]
So the third term is 14.

Solve for P if E = 2.50 and r = 2.00 given that E = P4πr2
Answer:
P = 0.05
Step-by-step explanation:
E = P4πr²
2.50 = P4π(2)²
2.50 = P4π4
2.50 = P(50.265)
P = 0.05

A circle has a circumference of 100 yd. Find its area.
Answer:
Area = 794.23 yd²Step-by-step explanation:
In order to find the area of the circle we must first find it's radius using the circumference
Circumference of a circle = 2πr
where
r is the radius
From the question
Circumference = 100 yd
So we have
100 = 2πr
Divide both sides by 2π
We have
[tex]r = \frac{100}{2\pi} \\ = \frac{50}{\pi} \\ = 15.91549[/tex]
We have
radius = 15.9 yd
Since we've found the radius we can use it to find the area
Area of circle = πr²
Area = (15.9)²π
Area = 252.81
= 794.226
We have the final answer as
Area = 794.23 yd² to 2 decimal places

What is the point-slope form of a line that has a slope of 3 and passes through point (1, 4)? O y-4=3(x-1) 0 1-y=3(x-4) O Y,- 4= 3(1-x) o 1-y=3(4-X)
Answer:
y - 4 = 3(x-1)
Step-by-step explanation:
The point slope form of a line is
y-y1 = m(x-x1)
where (x1,y1) is a point on the line and m is the slope
y - 4 = 3(x-1)
FA is a line, line segment, and a ray. tru or false
Answer:
The answer is "false".
Step-by-step explanation:
The following are the description of the line, line segment, and ray.
Line: The line is a single-dimensional figure, which has a length but no width. It has the direct path of points, which runs to the next without stopping in both directions. Line Segment: It is the portion of a line is called a segment. It has two end-points, which includes the endpoints for all the positions between these. The length of this section, can't be determined. Ray: The ray would be a straight path for one destination and moves one way.what is 10 +10×2÷8+5

The distance between numbers is the difference between them.
5/2 and 4 7/8
Using these pints the distance will be
5/2 - [tex]4\frac{7}{8}[/tex] is the same as -5/2 - 4 7/8
and is also not the same as 5/2 - (-4 7/8)
Answer:
C) None of the above
Step-by-step explanation:
The distance between 5/2 and 4 7/8 is 4 7/8-5/2= 39/8-20/8=19/8=2 3/8
A) |-5/2-4 7/8|=|-20/8-39/8|=|-59/8|=59/8= 7 3/8 SO NO
B) |5/2-(-4 7/8)|=|20/8+39/8|=|59/8|=59/8= 7 3/8 SO NO
C) None of the above = YES
While your answering dis question.... pls tell me why u r so good at math.... And don't just say because I am. Brainiest to the top answer
Step-by-step explanation:
f (x)=5x+1
Hence, In order to find f (-3), we must find the value of 5×-3 +1
Hence, Substituting x=-3,
p (-3)=5×-3 +1
= -15+1
= -14
If BD= 14 and CD= 4, then BC= ?
Remember that a segment that connects two points A and B is written as:
AB
Now, assuming that in this case the points B, D, and C are collinear, we can see that C is between B and D.
With this, we can find that BC = 10
Then we can write:
BD = BC + CD
And we know that:
BD = 14
CD = 4
we can replace thest two in the above equation to get:
14 = BC + 4
14 - 4 = BC
10 = BC
We just found that the value of the segment BC is 10.
