Help me please!! Asap thanks so much
Answer:
5 and 5
Step-by-step explanation:
[tex]AB = BC =\sqrt{(4-0)^2+(3-0)^2}=5[/tex]
Answer:
AB = 5
BC = 5
Step-by-step explanation:
The formula to find the distance between two points is: [tex]\sqrt{(x_2-x_1)^2 +(y_2-y_1)^2}[/tex]
AB: 5
The two points are A(-4,0) and B(0,3).
In the formula, it will be expressed as:
[tex]\sqrt{(0-(-4))^2+(3-0)^2}[/tex]
--> [tex]\sqrt{4^2+3^2}[/tex] .
--> [tex]\sqrt{16+9}[/tex]
--> [tex]\sqrt{25}[/tex]
--> 5
BC: 5
The two points are: B(0,3) and C(4,0)
In the formula, it will be expressed as:
[tex]\sqrt{(4-0)^2+(0-3)^2}[/tex]
--> [tex]\sqrt{(4)^2 + (-3)^2}[/tex]
--> [tex]\sqrt{16 + 9}[/tex]
--> [tex]\sqrt{25}[/tex]
--> 5
So both AB and BC is 5.

Therefore, the correct answer is option d. 17.1.
How to find Trevor's total employee benefits?If you would like to know Trevor's total employee advantages, you can estimate this utilizing the subsequent steps:
To find the percentage of the total employee benefits x% of $28,600 exists $33,500.
To estimate the value of x, bring the variable to the left side and bring all the remaining variables to the right side. Simplify the values to estimate the result.
x/100 [tex]*[/tex] 28,600 = 33,500
x = 33,500 [tex]*[/tex] 100 / 28,600
x = 117.13% = 117%
117% - 100% = 17%
x = 17%
The correct result would be 17%.
Trevor's total employee benefits exists 17.1% of his gross pay.
Therefore, the correct answer is option d. 17.1.

Step-by-step explanation:
Which of the x values are solutions to the inequality 4(2 – x) > –2x – 3(4x 1)? check all that apply.
The solution for the inequality given exists x > -11/10. The inequality contains an infinite number of solutions as long as it is greater than -11/10.
How to determine the value of x?
Given: 4(2 – x) > –2x – 3(4x + 1)
The inequality can be simplified to
8 - 4x > -14x - 3
subtract 8 from both sides of the equation, and we get
8 - 4x - 8 > -14x - 3 - 8
- 4x > -14x - 11
Add 14x from both sides
- 4x + 14x > -14x - 11 + 14x
10x > - 11
x > - 11/10
The solution for the inequality given exists x > -11/10. This means that any number greater than -11/10 exists as a solution to the inequality given. The inequality contains an infinite number of solutions as long as it is greater than -11/10.

Here is one way .... I showed you how to use Law of cosines in another Q
use this to find CB
CB^2 = 13^2 + 21^2 - 2(13)(21) cos 91 <==== solve for CB
THEN use law of SINES to find angle B
sin B / 21 = sin 91 / CB (CB you found using law of cosines above)
Answer:
m∠B = 57.5°
Explanation:
Use cosine rule:
a² = b² + c² - 2bc cos(A)
inserting values
a² = 21² + 13² - 2(21)(13) cos(91)
a² = 619.529
a = √619.529
a = CB = 24.89 km
Then use sine rule:
sin(A)/a = sin(B)/b
sin(91)/24.89 = sin(B)/21
sin(B) = 21sin(91)/24.89
sin(B) = 0.843583...
B = sin⁻¹(0.843583) = 57.52° ≈ 57.5°
A pyramid has the same volume as a cube of side 10.0 cm
The height of the pyramid is the same as the side of the square base
Calculate the height of the pyramid
Textbook says the answer is 14.4 cm but i don't understand how
Please explain with step by step explanation
The height of the pyramid is 14.4 cm.
How to find the height of the pyramid?volume of a pyramid = 1 / 3 Bh
where
B = base areah = height of the pyramidTherefore,
volume of the cube = L³
where
L = side length of the cubeHence,
volume of the cube = 10³
volume of the cube = 1000 cm³
The volume of the pyramid is the same with the volume of the cube.
Hence,
1000 = 1 / 3 Bh
The height of the pyramid is the same as the square base.
Therefore,
1000 = 1 / 3 (h²)h
1000 = 1 / 3 h³
cross multiply
3000 = h³
h = ∛3000
h = 14.4224957031
Hence, the height of the pyramid is 14.4 cm.

What is the value of x?
w
t
105°
80°
Answer:
x = 75°Step-by-step explanation:
Opposite angles in a cyclic quadrilateral are supplementary.
Applicationx° = 180° -105°
x° = 75°
__
The value of the other angle is similarly found:
w° = 180° -80°
w° = 100°
__
Additional comment
This result comes from the inscribed angle theorem. That theorem tells you the measure of the inscribed angle is half the measure of the intercepted arc.
The opposite angles of a cyclic quadrilateral intercept the circle at the same two points, dividing the total 360° circle into two parts. Each angle has a measure equal to half its corresponding arc, so the total of the two angles is half the total of the two arcs: 360°/2 = 180°. The angles are supplementary.

How long does it take the wave to travel 6.0 m in the x-direction? 0.13 seconds 0.67 seconds 2.0 seconds 8.0 seconds
It takes the time for the wave to travel 6.0 m in the x-direction of 8s.
What is the wavelength?A wave's wavelength is measured in meters since it is the separation between its two peaks (or troughs). Since waves can be any size or shape, the prefix for meters can vary significantly, from km for radio waves to micrometers for visible light (although it is sometimes stated in nanometers) to picometers for gamma rays..
According to the information:the wavelength is 1.5 m.
λ/2 = 1 s
1.5/2 =1 s
0.75 m in 1 s is travelled by the wave.
To travel 6m , the time required is

The coordinates of F is (8.5, 7)
How to determine the coordinates of F?The coordinates of the points are given as:
D = (-2, -5)
F = (5, 3)
DF : FE = 4 : 2
Rewrite the ratio as
m = 4 : 2
The coordinate of the partition is calculated as:
F = 1/(m + n) * (mx2 + nx1, my2 + ny1)
This gives
(5, 3) = 1/(4 + 2) * (4 * x + 2 * -2, 4 * y + 2 * -5)
Evaluate the sum and the product
(5, 3) = 1/6 * (4x - 4, 4y - 10)
Multiply both sides by 6
(30, 18) = (4x - 4, 4y - 10)
By comparison, we have:
4x - 4 = 30
4y - 10 = 18
Solve the equations
x = 8.5
y = 7
So, we have:
F = (8.5, 7)

The end behavior of the given polynomial is that as x → -∞ or x → ∞, then, f(x) → 5
What is the end behavior of the Polynomial?
We are given the polynomial;
f(x) = 5x/(x - 25)
Now, we want to find the limits as x → ±∞. Let us rearrange the given polynomial to get;
f(x) = 5/(1 - (25/x))
Thus, applying limits we have;'
lim x → ±∞ [5/(1 - (25/x))]
From algebraic limit laws we know that;
If f(x) = k, then;
lim x → +∞ [f(x)] = k
Also, lim x → -∞ [f(x)] = k
Thus, applying limits at infinity to our polynomial gives;
lim x → ±∞ [5/(1 - (25/x))] = 5/(1 - 0) = 5
This is because lim x → ∞ for 1/x is 0.
Thus, f(x) has horizontal asymptotes at y = 5
Thus, we conclude that the end behavior is that as x → -∞ or x → ∞, then, f(x) → 5

Find the área of the screen
Answer:
width: 37.6 inheight: 28.2 inarea: 1060.32 in²Step-by-step explanation:
The measurement used to describe a television is the length of its diagonal. The relation between the width, height, and diagonal is described by the Pythagorean theorem.
Diagonal unitsThe Pythagorean theorem tells us the relation between the sides of a right triangle and its hypotenuse. The diagonal of a rectangle is the hypotenuse of a right triangle whose sides are the width and height of the rectangle. If 'c' is the number of "ratio units" in the diagonal, we have ...
4² +3² = c²
c = √(16 +9) = 5
The diagonal of the screen is 5 ratio units, so the width is 4/5 of the length of the diagonal, and the height is 3/5 the length of the diagonal.
Screen dimensionsThe width is ...
(4/5)(47 in) = 37.6 in . . . width
The height is ...
(3/5)(47 in) = 28.2 in . . . height
AreaThe area is the product of the width and height:
A = WH = (37.6 in)(28.2 in) = 1060.32 in²
The area of the screen is 1060.32 square inches.

Based on this information, of the next 2000 pizzas he sells, how many should he expect to be stuffed crust or pan style? Round your answer to the nearest whole number. Do not round any intermediate calculations.
Answer:
797
Step-by-step explanation:
First, we need to find the number of pizzas sold last week by finding the sum of the pizzas sold:
307 + 224 + 161 + 191 = 883
Next, we need to find the proportion of stuffed crust and pan style pizzas sold last week by adding the number of both sold and dividing by the total number of pizzas sold:
(191+161) / 883 = 352 / 883
Now we need to multiply this proportion by 2000 to find the expected number of stuffed crust or pan style pizzas:
(352 / 883) * 2000 = 797.28 = 797

The greatest force acting on the ball to slow it down is Gravitational force.
Which forces will act on the ball?When ball is thrown upwards then there will be two forces on the ball opposite to the motion of ball
1. Gravitational force (mg)
2. Air friction or air drag
Both forces are opposite to the motion of the ball and it will cause the decrease in the speed of the ball.
Now here due to less value of drag coefficient on the ball we will say that ball will decrease its speed more due to gravitational force compare to friction force of air.
