What is the value of x? x = 2 x = 3 x = 4 x = 6
Answer:
The answer is 3
Step-by-step explanation:
The value of x is 3.
The correct option is B.
Use one of your formulas from the figure we can write
x(x+21) = (x+1)(x+1+14)
Now, solving for x we get
x² + 21x = (x+1)(x+15)
x² + 21x = x² + 15x + x + 15
x² + 21x= x² + 16x+ 15
21x = 16x+ 15
21x - 16x = 15
5x= 15
x= 15/5

A ball is thrown into the air with an upward velocity of 32 ft/s. Its height h in feet after t seconds is given by the function h = −16t2 + 32t + 6. In how many seconds does the ball reach its maximum height? Round to the nearest hundredth if necessary. What is the ball’s maximum height?
The ball's maximum height is [tex]\( \boxed{22} \)[/tex] feet.
To find the time at which the ball reaches its maximum height, we can first determine the vertex of the quadratic function [tex]\( h(t) = -16t^2 + 32t + 6 \),[/tex] where t represents time in seconds and h represents height in feet.
The vertex of a quadratic function [tex]\( ax^2 + bx + c \)[/tex] is given by the formula:
[tex]\[ t_{\text{max}} = \frac{-b}{2a} \][/tex]
For the function [tex]\( h(t) = -16t^2 + 32t + 6 \)[/tex], we have a = -16 and b = 32 . Plugging these values into the formula:
[tex]\[ t_{\text{max}} = \frac{-32}{2(-16)} \]\[ t_{\text{max}} = \frac{-32}{-32} = 1 \][/tex]
So, the ball reaches its maximum height at t = 1 second.
To find the maximum height, we substitute t = 1 into the function h(t) :
[tex]\[ h(1) = -16(1)^2 + 32(1) + 6 \]\[ h(1) = -16 + 32 + 6 \]\[ h(1) = 22 \][/tex]
Therefore, the ball's maximum height is [tex]\( \boxed{22} \)[/tex] feet.

Which of the following would triple the volume of the Egyptian square-based Pyramid below?
A. Multiply only the height by 3.
B. Add 3 to each dimension of the Pyramid.
C. Multiply every dimension of the Pyramid by 3.
D. Add 3 to the slant height.
Final answer:
To triple the volume of a square-based Egyptian pyramid, you must multiply every dimension of the pyramid by 3. This is because volume is proportional to all three dimensions of the shape, and changing just one dimension won't achieve the desired effect.
Explanation:
The question asks which action would triple the volume of a square-based Egyptian pyramid. The volume (V) of a pyramid is calculated using the formula V = (1/3) × base area × height. To triple the volume, you would need to triple the factor of each dimension because volume is a three-dimensional measurement, and changing one dimension alone would not be sufficient.
Option A suggests multiplying only the height by 3, but this would not triple the volume as the base area remains the same. Option B suggests adding 3 to each dimension, but adding a constant to linear dimensions does not maintain a proportional relationship to volume.
Option D suggests adding 3 to the slant height, which does not directly correlate to the volume. Therefore, option C is correct: Multiplying every dimension of the Pyramid by 3 would indeed triple the volume because changing each dimension equally maintains the proportion. This is similar to how if a block's dimensions were doubled (2L × 2L × 2L), the new volume would be 8 times the original (8L³).

an initial deposit of $200 is made into an account that pays 4.2% annual interest. What is a model to represent the balance in the account after x years?
The model to represent the balance in an account from an initial deposit of $200 at an annual interest of 4.2% is given by the formula A = 200(1.042)^x. Here A is the amount accrued after x years.
Explanation:The subject of the given problem is related to exponential growth as it involves the growth of a principal amount in a bank account accruing annual interest. The model to represent the balance in the account after x years can be described by the formula A = P(1 + r/n)^(nt). Where, A represents the amount of money accumulated after n years, including interest. P is the principal amount (the initial amount of money), r is the annual interest rate (in decimal form), n is the number of times that interest is compounded per year, t is the time the money is invested for in years.
In this case, P = $200, r = 4.2/100 = 0.042 (converted percentage to decimal), n = 1 (since it is compounded annually), and t = x (number of years). Substituting these values into the formula, we obtain the model: A = 200 (1 + 0.042) ^ (1*x) simplified to, A = 200(1.042)^x. Which is used to represent the balance in the account after x years.

An equation of a line that is the perpendicular bisector line segment AB is y=-x+10.
What is the equation of a line?The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.
Given that, line segment AB is defined by the endpoints A(4,2) and B(8,6).
Midpoint of line AB is (x, y) =[(x₂+x₁)/2, (y₂+y₁)/2]
= [(8+4)/2, (6+2)/2]
= (6, 4)
Slope of line AB is (y₂-y₁)/(x₂-x₁)
= (6-2)/(8-4)
= 4/4
= 1
The slope of a line perpendicular to given line is m1=-1/m2
So, the slope of a line is -1
Now, substitute m=-1 and (x, y)=(6, 4) in y=mx+c, we get
4=-1(6)+c
c=10
Substitute m=-1 and c=10 in y=mx+c, we get

C. 425 degree+(960n)degree, for any integer n
D. 425 degree+(1,440n)degree, for any integer n
We know that co terminal angles are those angles which have a difference equal to a multiple of 360 degrees. For example co terminal angle of 45 degrees is 76 degrees because their difference is equal to 720 degrees, which is a multiple of 360.
We have been given an angle 425 degrees.
From the given choices, we need to check if angles being added or subtracted to 425 degrees are multiples of 360 or not.
Let us check each of the options one by one.
(A) The angle being subtracted is [tex]1000n[/tex]. Therefore, we have [tex]\frac{1000n}{360}=2.77n[/tex], which is not an integer for all values of n. Therefore, angle given in this option is not a co terminate angle to 425 degrees.
(B)
The angle being subtracted is [tex]840n[/tex]. Therefore, we have [tex]\frac{840n}{360}=2.33n[/tex], which is not an integer for all values of n. Therefore, angle given in this option is not a co terminate angle to 425 degrees.
(C)
The angle being added is [tex]960n[/tex]. Therefore, we have [tex]\frac{960n}{360}=2.67n[/tex], which is not an integer for all values of n. Therefore, angle given in this option is not a co terminate angle to 425 degrees.
(D)
The angle being added is [tex]1440n[/tex]. Therefore, we have [tex]\frac{1440n}{360}=4n[/tex], which is an integer for all values of n. Therefore, angle given in this option is indeed a co terminate angle to 425 degrees.
Hence, correct answer is option (D).

ABCD is an isosceles trapezoid with legs AB and CD, and base BC. If the length of AB = 6y +5, the length of BC= 4y - 6, and the length of CD= 2y +1, what is the value of y?
To find the value of y in the given isosceles trapezoid ABCD, we can set up an equation AB = CD and solve for y.
Explanation:To find the value of y in the given isosceles trapezoid ABCD, we can set up the equation AB = CD and solve for y.
Given that AB = 6y + 5 and CD = 2y + 1, we have the equation 6y + 5 = 2y + 1.
Simplifying this equation, we can subtract 2y from both sides to get 4y + 5 = 1.
Finally, subtracting 5 from both sides gives us 4y = -4.
Dividing both sides of the equation by 4, we find that y = -1.
To find the value of y in an isosceles trapezoid ABCD with given side lengths in terms of y, we set the equations for the congruent legs, AB = 6y + 5 and CD = 2y + 1, equal to each other and solve for y, arriving at y = -1.
Explanation:To find the value of y in an isosceles trapezoid where the lengths of the sides are given in terms of y, we can utilize the properties of an isosceles trapezoid. In an isosceles trapezoid, the legs (non-parallel sides) are congruent. Given that AB = 6y + 5 and CD = 2y + 1, and these lengths must be equal for ABCD to be an isosceles trapezoid, we can set up the following equation:
6y + 5 = 2y + 1
Solving for y, we subtract 2y from both sides to get:
4y + 5 = 1
Now, subtract 5 from both sides:
4y = -4
And finally, divide by 4 to find y:
y = -1
Thus, the value of y is -1.

in the polynomial function F(x)=1/2x^2+8-5x^3-19x what is the leading the coefficient
Answer:
-5
Step-by-step explanation:
The leading term in a polynomial consist on the highest degree term. To get the highest degree term, we need to reorder the polynomial from left to right, starting with the highest degree term.
In this case:
[tex]f(x)=\frac{1}{2} x^{2} +8-5x^{3} -19x[/tex]
reordering
[tex]f(x)=-5x^{3} +\frac{1}{2}x^{2} -19x+8[/tex]
So, the leading coefficient is the one with the leading term:
[tex]-5x^{3}[/tex]
So, it is -5
