Answer:
x= 5 /2 , − 4
Step-by-step explanation:
Factor and set each factor equal to zero.
Answer: x=-4, x=5/2
Step-by-step explanation:
To factor the expression, you want to break up the expression into 2 parts.
2x²+3x-20
(2x²-5x)+(8x-20) [factor each part]
x(2x-5)+4(2x-5) [take out x+4]
(x+4)(2x-5) [set each factor equal to 0]
x=-4
x=5/2
Now, we know that x=-4 and x=5/2.

If f(x) = 4x3 - 2x and g(x) = x3 + 6x2 + 3x - 7, then find f(x)
+ g(x)
Answer:
5x^3+6x^2+x-7
Step-by-step explanation:
f(x) = 4x^3 - 2x and g(x) = x^3 + 6x^2 + 3x - 7,
f(x) + g(x)= 4x^3 - 2x+ x^3 + 6x^2 + 3x - 7
4x^3 + x^3 + 6x^2 + 3x- 2x - 7
Combine like terms
5x^3+6x^2+x-7

Which function has zeros of -8, 1, and 3? A. y = (x − 3)(x + 8)(x − 1) B. y = (x + 1)(x − 8)(x + 3) C. y = x(x + 8)(x − 3) D. y = x(x + 3)(x − 8)
Answer:
A
Step-by-step explanation:
In each binomial, just flip the sign before the constant, and that number is a zero.
So for example if you have (x+1), a zero would be -1, if you have (x-8), a zero would be 8, etc.
The zeros of a function are the values of x, when the function equals 0.
The function that has zeros of -8, 1 and 3 is: (a) [tex]\mathbf{ y = (x - 3)(x + 8)(x - 1)}[/tex]
The zeros are given as:
[tex]\mathbf{Zeros = -8, 1, 3}[/tex]
Rewrite as:
[tex]\mathbf{x = -8, 1, 3}[/tex]
Equate to 0
[tex]\mathbf{x +8 = 0,\ x - 1 = 0,\ x - 3 = 0}[/tex]
Multiply the equations
[tex]\mathbf{(x +8) \times (x - 1) \times (x - 3) = 0\times 0 \times 0}[/tex]
[tex]\mathbf{(x +8) \times (x - 1) \times (x - 3) = 0}[/tex]
Express as a function
[tex]\mathbf{y = n(x +8) \times (x - 1) \times (x - 3) }[/tex]
Where:
[tex]\mathbf{n \ne 0}[/tex]
The above equation represents functions that have zeros of -8, 1, and 3
By comparing the options, we have:
[tex]\mathbf{ y = (x - 3)(x + 8)(x - 1)}[/tex] is [tex]\mathbf{y = n(x +8) \times (x - 1) \times (x - 3) }[/tex], where n = 1
Hence, the function that has zeros of -8, 1 and 3 is:
(a) [tex]\mathbf{ y = (x - 3)(x + 8)(x - 1)}[/tex]

Find the point that lies 1/8 of the way on the line A to B, given that A is at -14 and B is at 10.
Answer:
-11
Step-by-step explanation:
Find the distance from point A to point B.
|-14 - 10| = |-24| = 24
Now find 1/8 of the distance from A to B.
1/8 * 24 = 24/8 = 3
Add 3 to the coordinate of point A.
-14 + 3 = -11
Answer: -11
Answer:
the point that lies at 1/8 from A = -11
Step-by-step explanation:
1/8
v
A --------------------|---------------B
-14 0 10
14 + 10 = 24
1/8 x 24 = 3
distance from point A = 3
therefore,
the point that lies at 1/8 from A = -11

You are a doctor working at Kaiser. You want to test a new drug for cancer patients who are being treated in your hospital. You have a good feeling that this drug will work. You have 100 patients on which to test your new drug.
a. What is your hypothesis?
b. What is the experiment?
c. What is the control group?
d. What is the experimental group?
e. What is the independent variable?
f. What is the dependent variable?
Answer:
A) Hypothesis: IF the new drug are given to cancer patients, THEN they will recover.
B) The experiment is testing the effect of the new drug on the recovery of cancer patients
C) The control group can be the group of patients that does not receive the new drug
D) The experimental group are the patients on which the new drug were tested on.
E) The independent variable is the NEW DRUG
F) The dependent variable is the RECOVERY OF THE CANCER PATIENTS.
Step-by-step explanation:
1) In an experiment, the hypothesis is a testable explanation given to provide a possible answer to an observed problem. In this case, a hypothesis can be: IF the new drug are given to cancer patients, THEN they will recover.
2) The experiment is conducted in order to test if the hypothesis will be ACCEPTED OR REJECTED. In this case, the experiment being conducted is to test the effect of the new drug on the recovery of cancer patients.
3) The control group in an experiment is the group that does not receive the experimental treatment, which is the new drug in this case. Hence, the control group will be the group of patients that does not receive the new drug.
4) In contrast to the control group, the experimental group is the group that receives the experimental treatment (new drug). In this case, the experimental group are the patients on which the new drug were tested on.
5) The independent variable is the variable that the experimenter manipulates or changes in the experiment. In this case, the independent variable is the NEW DRUG.
6) The dependent variable is the variable that the experimenter measures or the variable that responds to the changes made to the independent variable. In this case, the dependent variable is the RECOVERY OF THE CANCER PATIENTS.

The trigonometric expressions equal to - 1/2 is cos(120°).
What is sign of trigonometric functions?For every point P (a, b) on the unit circle, – 1 ≤ a ≤ 1 and – 1 ≤ b ≤ 1, we have – 1 ≤ cos x ≤ 1 and –1 ≤ sin x ≤ 1 for all x. Also, we can define the values of a and b in different quadrants as:
First quadrant: 0 < x < π/2 ⇒ a and b are positive
Second quadrant: π/2 < x < π ⇒ a is negative and b is positive
Third quadrant: π < x < 3π/2 ⇒ a and b are negative
Fourth quadrant: 3π/2 < x < 2π ⇒ a is positive and b is negative.
We know that,
cos(180° - θ) = -cosθ
According to question,
cos(120°)
= cos(180° - 60°)
It comes in 2nd quadrant where cos is negative.
= -cos60°
= - 1/2
Hence the trigonometric expressions equal to - 1/2 is cos(120°).
