Find the length of side x in simplest radical form with a rational denominator
Answer:
The answer is "[tex]\frac{7\sqrt{3}}{2}[/tex]"
Step-by-step explanation:
[tex]\to \sin 60^{\circ} = \frac{x}{7} \\\\\to x=\sin 60^{\circ} \times 7 \\\\\therefore \sin 60^{\circ} = \frac{\sqrt{3}}{2} \\\\\to x= \frac{\sqrt{3}}{2}\times 7 \\\\\to x= \frac{7\sqrt{3}}{2}[/tex]
What is the correct ratio?
D)32/40
Hope it helps you
Answer:
[tex]\frac{24}{40}[/tex]
Step-by-step explanation:
Sin = [tex]\frac{opposite}{hypotenuse}[/tex] (relative to the angle asked for)
The opposite of Angle Z is 24
The hypotenuse no matter what would always be 40; therefore,
Sin(Z) = [tex]\frac{24}{40}[/tex]

What linear equation is represented by the table?
Please hurry!
Best answer gets Brainliest!!!!
A) Y= 2x
B) y= 4x
C) y= 4x -2
D) y= 2x - 2
Answer:
y = 4x - 2
Step-by-step explanation:
linear equation - y = mx + b
where m = slope and b = y intercept
The y intercept is the y value of the coordinate where x = 0
Looking at the table, we notice that when x = 0, y = -2
Which means that the y intercept ( b ) = -2
Slope = change in y over change in x
As y goes up 4 x goes up 1
Thus, slope ( m ) = 4
Now we plug in the identified slope and y intercept into " y = mx + b "
we get that the equation is y = 4x - 2

What is 6 1/3 yards in feet with explication
Answer:
6 1/3 yards = 19 feet
Step-by-step explanation:
1 yard = 3 feet
So we'll take the number of yards and multiply that by 3
6 yards x 3 feet/yard = 18 feet
for the 1/3 of a yard, you can either ask, "what's 1/3 of 3?" (= 1) or you can multiply 1/3 yard x 3 feet/yard = 1 foot.
Add up the parts, 18 + 1 = 19 feet

Answer:
a) 1/2
b) 1/2
Step-by-step explanation:
a) The average rate of change is the slope of the segment whose end points are the ends of the interval. On the interval [2, 8] the average rate of change is ...
m = (f(8) -f(2))/(8 -2) = (4 -1)/6 = 3/6 = 1/2
The average rate of change on the interval [2, 8] is 1/2.
__
b) In this context, "slope" and "average rate of change" mean the same thing. A line with the same slope will have a slope of 1/2.
Angle PKL and angle MKN are complementary angles. The measure of angle PKL is twice the measure of angle MKN.
a. Write one equation to find x,
b. What is the measure of angle MKN
c. Solve for x.
Answer:

The graph of the function f(x) = cos(x) is shown.
What is the range of the function?
A. [-3,3]
B. (-00, 00)
C. [-1, 1]
D. (0, 2m)
Answer:
C
Step-by-step explanation:
bottom to top
it goes from -1 to 1
The required range of the function y= cosx is [-1, 1]. Option C is correct.
From the graph range of the function y = cosx is to be determined.
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is independent while Y is the dependent variable.
What is range?The range is defined as the difference between higher and lower values of y = f(x).
In a graph the value of y = f(x) = cosx is defined for every x of its domain (-∞, ∞) it varies from minimum -1 to maximum +1 on the y axis, so the range of the function is [ -1, 1].
Thus, the required range of the function y= cosx is [-1, 1]. Option C is correct.

Find the radius of a sphere with a surface area of $4\pi$ square feet.
Answer:
r = 1 feet
Step-by-step explanation:
Given that,
The surface area of the sphere, A = 4π feet²
We need to find the radius of the sphere.
The formula for the surface area of the sphere is given by :
[tex]A=4\pi r^2[/tex]
Where
r is the radius of the sphere
Put all the values,
[tex]4\pi = 4\pi \times r^2\\\\r=1[/tex]
So, the radius of the sphere is equal to 1 feet.

Answer:
B
Step-by-step explanation:
So, this is a inequality.
The inequality is 2x+2 >= 10
Lets completly ignore the graphs for the moment, and just solve this inequawlity as we would like a normal equation.
So first, subtract 2 from both sides:
2x+2>=10
=
2x>=8
Now, divide by 2 to get x alone:
2x>=8
=
x>=4
So, we now know that x is greater than or equal to 4.
In a normal inequality, we would have to remember the following:
When it is greater than/less than or equal to the dot that marks the inequalities value is filled in.
When it is greater than/less than the dot that marks the inequalities value is open, kind of like a "o".
Also, recall that the dark black line that goes either left or right of the dot also varies:
If x is less than the dot that marks the inequalities value, then the dark black line with go left.
If x is greater than the dot that marks the inequalities value, then the dark black lne will go right.
So for our x>=4, since there is a equals sign, its a filled in dot.
So four our x>=4, since there is a greater than sign, the dakr black lines goes to the right.
Now, lets look at the graphs
There is only one that has the filled in dot on 4, and a black line that goes to the right. Thats B
So B is your answer!
Hope this helps! :)
Answer:
B
Step-by-step explanation:
In order to graph we must first isolate the variable.
We can do this by using inverse operations
2x + 2 ≥ 10
To get rid of the + 2 we subtract 2 because the expression is adding 2 and the inverse of addition is subtraction. But remember whatever we do to one side we have to do to the other so we subtract 2 from each side
2 - 2 cancels out
10 - 2 = 8
we now have 2x ≥ 8
Now we want to get rid of the 2 on "2x". 2x is the same as 2 times x and the inverse of multiplication is division, so we divide each side by 2
2x / 2 = x
8 / 2 = 4
we're left with x ≥ 4
To graph we place a point on "4" and fill in the point ( when the inequality sign is ≤ or ≥ we fill in the point )
When the inequality sign is facing the variable ( x ) the line will be going in the direction of right.
Hence, the answer is B

Find the probability that x<-3
This is the probability that corresponds to x = -5, which is less than x = -3, and it's the only x value of the list smaller than -3. There's not much else to say about this.
If we wanted to find something like P(X < -2), then we would add up the probabilities for x = -5 and x = -3 to get 0.17+0.13 = 0.30
Which Which value of x makes this equation true? -3x+10=5x-8
value of x makes this equation true? -3x+10=5x-8
Answer:
9/4
Step-by-step explanation:
-3x+10=5x-8
or, -3x-5x = -8-10
or, -8x=-18
or, 8x=18 (i.e. - is cancelled)
or, x=18/8
i.e. x=9/4
Hence, the value of x is 9/4
Answer:
The value of x is 9/4
Step-by-step explanation:
-3x+ 10 = 5x - 8
Add 3x both side
-3x + 3x + 10 = 5x + 3x - 8
10 = 8x - 8
Now, Add 8 both side
10 + 8 = 8x - 8 + 8
18 = 8x
8x = 18
Now, Divide by 8 from both side
8x/8 = 18/8
x = 9/4
Thus, The value of x is 9/4
FOR VERIFICATION ONLY:-3x + 10 = 5x - 8
-3(9/4) + 10 = 5(9/4) - 8
-27/4 + 10 = 45/4 - 8
-27 + 4 × 10/4 = 45 - 8 × 4/4
-27 + 40/4 = 45 - 32/4
13/4 = 13/4
Hence, L.HS = R.H.S

Answer:
A. The volumes are equivalent.
Step-by-step explanation:
The volume of a pyramid can be found using the formula ...
V = 1/3Bh
where B is the base area, and h is the height.
Both of these pyramids have the same height, so we can compare volumes by looking at the base area.
Prism X has a rectangular base with an area of A = LW = (6 cm)(5 cm) = 30 cm². Prism Y has a triangular base with an area of A = 1/2bh = 1/2(7.5 cm)(8 cm) = 30 cm².
The two base areas are the same, so the volumes are the same.

Answer:
144 - 36pi
Step-by-step explanation:
1) Since the side lengths of the square are 12 units, the midpoints divide each side into two 6 unit lengths.
2) Those 6 unit lengths are radii of a quarter of a circle.
3) We can use the equation pi × r^2 to calculate the area of the four quarter circles.
4) pi × 6^2
5) 36pi
6) The area of the original square is 12 × 12, which is 144.
7) 144 - 36pi is your answer.
