Graph the function f(x)= square root over x. Which table of values contains points that lie on the graph of the function?
Answer:
see attached
Step-by-step explanation:
The square root of a negative number is undefined, so the applicable table is the one shown below.
Answer:
Table 3 represents the correct points that lie on the graph of the function.
Step-by-step explanation:
We are given the function:
[tex]f(x) = \sqrt{x}[/tex]
We have to plot the given function.
The attached image shows the graph for the given function.
Putting values for x in the function we get:
[tex]f(x) = \sqrt{x}\\f(-1) = \sqrt{-1}[/tex]
which is undefined.
[tex]f(0) = \sqrt{0} = 0\\f(1) = \sqrt{1} = 1[/tex]
Table 3 represents the correct points that lie on the graph of the function.

Which of these is equal to sin 21°?
A) cos 21°
B) cos 69°
C) sin 69°
D) tan 69°
Answer:
B. Cos 69°
Step-by-step explanation:
Given : sin 21°
Solution : To show how Cos 69 ° = Sin 21 °
we will use sine and cosine trigonometric identity
i.e. Cos (90 °-x) = Sin x ---(A)
We are given Sin 21 °
So, putting x =21 ° in (A)
We are getting : Cos(90 °-21 °) = Sin 21 °
⇒Cos 69 ° = Sin 21 °
Hence it is shown that Cos 69 ° = Sin 21 °
Determine if the graph of r = 4cos 5θ is symmetric about the x-axis, the y-axis, or the origin.
Answer:
y-axisStep-by-step explanation:
The function graph is symmetric about
- the y-axis when it is an even function
- the origin when it is an odd function.
A symmetrical graph about the x-axis is not a function graph.
f(x) is an even if and only if f(-x) = f(x).
f(x) is an odd if and only if f(-x) = -f(x).
We have the function r(θ) = 4cos(5θ)
(olny symmetry about the y-axis or about the origin)
Check r(-θ):
r(-θ) = 4cos(5(-θ)) = 4cos(-5θ) = 4cos(5θ)
used cos(-x) = cos x
We have r(-θ) = r(θ). Therefore the graph of r(θ) is symmetric about the y-axis.
Answer:
x-axis
Step-by-step explanation:
if r%28theta%29+=+r%28-theta%29.
Since 4cos%285%2Atheta%29+=+4cos%28-5%2Atheta%29, the graph is symmetric wrt the x-axis.
The graph is symmetric wrt the y-axis if r%28theta%29+=+r%28pi-theta%29.
Since 4cos%285%2Atheta%29+%3C%3E+4cos%285%2A%28pi+-+theta%29%29+=+-4cos%285%2Atheta%29+, the graph is not symmetric wrt the y-axis.
The graph is symmetric wrt the y-axis if r%28theta%29+=+r%28pi%2Btheta%29.
Since 4cos%285%2Atheta%29+%3C%3E+4cos%285%2A%28pi+%2B+theta%29%29+=+-4cos%285%2Atheta%29+, the graph is not symmetric wrt the origin.

(3c2 + 2d)(–5c2 + d) Select all of the partial products for the multiplication problem above.
Answer:
2d^2
-15c^4
-10c^2 d
3c^2d
Step-by-step explanation:
Just had the question, good luck lovelies! :)
The partial products for the expression (3c² + 2d)(-5c² + d) are -15c⁴, 3c²d, -10c²d, and 2d².
The multiplication of the expression (3c² + 2d)(-5c² + d) step by step,
(3c² + 2d)(-5c² + d)
To find the partial products, we'll use the distributive property, which states that for any numbers a, b, and c:
a(b + c) = ab + ac
Now, applying this to your expression:
3c² × -5c²:
Multiply 3c² by -5c².
Result: -15c⁴
3c² × d:
Multiply 3c² by d.
Result: 3c²d
2d × -5c²:
Multiply 2d by -5c².
Result: -10c²d
2d × d:
Multiply 2d by d.
Result: 2d²
Therefore, these are the partial products obtained when multiplying the given expressions.
-15c⁴
3c²d
-10c²d

In the xy-plane, if (-1, 0) is a solution to the system of inequalities y < x + c and y < -x - d, which of the following must be true about c and d? (10 POINTS + BRAINLIEST ANSWER!!)
A. c = d
B. c = -d
C. c < d
D. d < c
Final answer:
By substituting the point (-1, 0) into the inequalities, we find that c must be greater than 1, and d must be less than 1, which means the correct answer is D. d < c.
Explanation:
We are given a point (-1, 0) which is a solution to both inequalities y < x + c and y < -x - d. To find the relationship between c and d, let's plug in the x and y values of the point into each inequality.
For y < x + c, with x = -1 and y = 0, we get:
0 < -1 + c
c > 1. (1)
For y < -x - d, with x = -1 and y = 0, we get:
0 < 1 - d
d < 1. (2)
Comparing (1) and (2), we see that c must be greater than 1 and d must be less than 1. Thus, the correct answer is D. d < c.

What is a solution set to an inequality or an equation?If the equation or inequality contains variable terms, then there might be some values of those variables for which that equation or inequality might be true. Such values are called solution to that equation or inequality. Set of such values is called solution set to the considered equation or inequality.
We need to replace the values of x and y of the point into the inequality, and if all conditions are respected, they are solutions.
Given inequality is
y > 2x -4
The points that are solutions given as follow:
1. (–2, –5)
y > 2x -4

8.42 x 10^3, Between which of the following pairs of numbers does the above number lie? A. .0083 and .0084 B. .0084 and .0085 C. 8300 and 8400 D. 8400 and 8500
The number 8.42 x 10³ lies in between pairs of numbers 8400 and 8500.
Option D is correct.
What is PEDMAS?The abbreviation PEMDAS is used to indicate the sequence of steps to be taken when resolving expressions with multiple operations.
PEMDAS stands for P- Parentheses, E- Exponents, M- Multiplication, D- Division, A- Addition, and S- Subtraction.
We have the number 8.42 x 10³.
Now, expanding the exponents we get
= 8.42 x 10³
= 8.42 x 1000
= 84.2 x 100
= 842 x 10
= 8420
Thus, the values lie between 8400 and 8500.

In circle K, what is the value of x?
x = 30°
x = 25°
x = 20°
x = 15º
Answer:
The correct option is 4.
Step-by-step explanation:
Given information: K is the center of the circle. AB is the diameter of the circle.
Angle subtended by a diameter is always a right angle. It the means the measure of that angel is 90 degree.
[tex]\angle C=90^{\circ}[/tex]
According to the angle sum property, the sum of interior angles of a triangle is 180 degree.
Using angle sum property in triangle ABC, we get
[tex]\angle A+\angle B+\angle C=180^{\circ}[/tex]
[tex]75^{\circ}+x+90^{\circ}=180^{\circ}[/tex]
[tex]x=15^{\circ}[/tex]
Therefore the measure of x is 15 degree. Option 4 is correct.

The sum of two consecutive even integers is at most 400. Find the pair of integers with the greatest sum
The largest pair of consecutive integers are 198 and 200.
Explanation: hope it helpsIf the sum of two equal even numbers is 400, the numbers will be 200+200.
Therefore the largest possible consecutive even numbers which have a sum of 400 or less are 198 and 200 which have a sum of 398.
Any pair of consecutive numbers less than these will have a sum of less than 400.
