Function A and Function B given below are linear functions, which statement is
true?
Answer:
a
Step-by-step explanation:
Answer:
A.
Step-by-step explanation:
Slope Formula: Y2 - Y1/ X2 - X1
Function A: 15 + 25/ 4 + 4 = 5; Slope = 5
Function B: 4 - 2/ 3-2 = 2; Slope = 2
The slope of Function A is greater than the slope of Function B.

A cylinder with radius 6 cm and height h cm has the same volume as a sphere with radius 4.5cm
Find the value of h.
(The volume, V, of a sphere with radius r is V=4/3pie r^3)
Answer:
h = 4.22 cm
Step-by-step explanation:
Mathematically, we have the volume of a cylinder as;
V = pie * r^2 * h
We have it that the radius is 6 cm
V = pie * 6^2 * h
for the sphere, we have it that;
V = 4/3 * pie * r^3
V = 4/3 * pie * 4.5^3
We can proceed to equate both volumes;
pie * 6^2 * h = 5/3 * pie * 4.5^3
pie on both sides cancel out
6^2h = 5/3 * 4.5^3
36h = 151.875
h = 151.875/36
h = 4.22 cm
Parralel lines cut by a transversal coloring activity. Please give explanation. Will give brainiest.
Step-by-step explanation: Do You Want Me To Find All The Values ?
Parallel lines intersected by a common transversal form 8 angles
The required values of y and x are;
5. y = 42°6. y = 29.5°7. y = 9°8. y = 14°9. y = 31°10. x = 20°11. x = 13°12. y = 39°The reasons why the above values are correct are given as follows:
Given the lines are parallel lines cut by a common transversal, we have;
Angles with measure (2·y - 1)° and (9·x - 38)° are same side interior angles
Angles with measure (4·x + 23)° and (2·y - 1)° are alternate interior angles
Which gives;
(2·y - 1)°+ (9·x - 38)° = 180°...(1)
(4·x + 23)° = (2·y - 1)°...(2)
From equation (1), we get;
y = 109.5 - 4.5·x
From equation (2), we get;
y = 2·x + 12
The common solution is given by; 109.5 - 4.5·x = 2·x + 12
From 109.5 - 4.5·x = 2·x + 12, we get;
x = 15,
y = 42°6) (9·x + 42)° and 15·x° are vertical angles, and therefore are equal
(9·x + 42)° = 15·x°
∴ x = 7
(4·y - 13)° and (9·x + 42)° are supplementary, therefore
(4·y - 13)° = (9·x + 42)°, which gives;
(4·y - 13)° = (9×7 + 42)° = 105°
y = 29.5°7) (3x + 11) + (x + 21) = 180
∴ x = 37
(14·y - 4)° = 3x + 11 = 3 × 37 + 11 = 122°
y = 9°8) (13·x - 33) = 10·x
∴ x = 11
10·x + 5·y = 180
10 × 11 + 5·y = 180
[tex]y = \dfrac{70^{\circ}}{5} = 14^{\circ}[/tex]
y = 14°9) (27·x + 4) + (8·x + 1) = 180
∴ x = 5
y + 10 = 8·x + 1 = 8 × 5 + 1 = 41
y = 41 - 10 = 31
y = 31°10) 16·x - 4 = 9·x - 6 + 58 = 9·x + 52
7·x = 56
x = 8
11) (6·x - 58)° + (x + 8)° = 90°
7·x - 50 = 90
7·x = 90 + 50 = 140
[tex]x = \dfrac{140}{7} = 20[/tex]
x = 20°12) 7·x - 7 = 3·x + 45°
4·x = 52
[tex]x = \dfrac{52}{4} = 13[/tex]
x = 13°
(3·x + 45)° + 63° + (y - 6)° = 180°
(3×13 + 45)° + 63° + (y - 6)° = 180°
147 + (y - 6)° = 180°
y = 39°Learn more about the angles formed between parallel lines here:

A random variable X follows a Binomial distribution; i.E. X ~ B(12, p) with a variance of 1.92. Compute the possible values of p
==================================================
Explanation:
Any binomial distribution has two unique components to it: The number of trials n, and the probability of success p.
We're given n = 12, and we need to find p.
The variance of a binomial probability distribution is given by the formula n*p*(1-p). Plug in n = 12 and set this equal to 1.92
So the equation to solve is 12p*(1-p) = 1.92
Solve for p using a graphing calculator or you could apply the quadratic formula. Either way, you should get the two results of p = 0.2 and p = 0.8
Note that if p = 0.2, then 1-p = 1-0.2 = 0.8, and things flip around when p = 0.8.

5. Find dy/dx of
of the following
the following functions
y²= 4ax
Answer:
A general rule for functions of the general form:
y = A*x^n
is:
dy/dx = n*A*x^(n - 1)
Then, for the function:
y^2 = 4*a*x
Then we can rewrite this as:
y = (4*a*x)^(1/2) = √(4*a)*x^(1/2)
Then we have:
A = √(4*a)
n = 1/2
Now we can use the above rule to get
dy/dx = (1/2)*√(4*a)*x^(1/2 - 1)
dy/dx = (1/2)*√(4*a)*x^(-1/2)
dy/dx = (1/2)*√(4*a/x)
dy/dx = √(1/4)*√(4*a/x)
dy/dx = √( (1/4)*4*a/x)
dy/dx = √(a/x)
If one side of a regular pentagon is represented by 3x + 1 , what is the perimeter of the pentagon?
Answer:
5(3x+1) or 15x+5
Step-by-step explanation:
A regular pentagon has 5 sides of equal length. The perimeter is the sum of the lengths of those sides. We can use multiplication to find the sum of 5 of the same value:
P = 5(3x +1)
Perhaps you want it expanded. Using the distributive property, we multiply each term in parentheses by 5:
P = 15x + 5

Step-by-step explanation:
The equation is a parabola, that opens up downwards, and the point from which Sarah throws the ball is 5 feet off the ground. so set the height to zero ( when the ball reaches the ground ) and solve for t
0 = -16[tex]t^{2}[/tex] + 18t + 5
use quadratic equation :)
-b +- sqrt([tex]b^{2}[/tex] - 4ac) / 2a
-18 +- sqrt[ [tex]18^{2}[/tex] - 4 (-16)(5) ] / 2(-16)
-18 +- sqrt[324 +320 ] / -32
-18 +- sqrt[644] / -32
-18 +- 25.377155 / -32
do the positive choice :
-18 + 25.377155 / -32
7.377155 / -32
-0.2305 ( so this answer would be where the ball would hit the ground if the arc extended down to the ground behind where Sarah throws the ball from. so this answer doesn't count in our domain. Because it's before Sarah throws the ball)
do the negative choice:
-18 - 25.377155 / -32
1.355536 ( this answer looks good, about 1.35 seconds for the ball to fly , this was more of a toss than a throw. )
t = 1.4 seconds ( rounded to nearest 10th )

Mathematics Mathematics, 29.12.2020 18:30, lame3245 a grandfather is nine times older than his granddaughter. In 8 years the grandfather will be five times older than his granddaughter how old is each of them now?
Answer:
Granddaughter = 8
Grandfather = 72
Step-by-step explanation:
Let :
Granddaughter's age = x
Grandfather's age = y
y = 9x
Age in 8 years :
Granddaughter's age = x + 8
Grandfather's age :
y + 8 = 5(x + 8)
y = 9x
Then ;
9x + 8 = 5(x + 8)
9x + 8 = 5x + 40
9x - 5x = 40 - 8
4x = 32
x = 32 / 4
x = 8
y = 9x = 9*8 = 72
