A material has an initial quantity of 20 units. Which equation models the amount of the material, y, growing exponentially at a rate of 17% for time, X?
y = 20(1.17)x
y=20(2.7)x
y=20(0.83)x
y=20(17)x
y = 17(1.2)x
y=20[tex]2.7^{x}[/tex] is the equation models that describes the growth rate of metal whose initial quantity is 20 units.
What is exponential functions?It is inverse of the logarithmic functions.
How to form exponential function?We have been given the initial quantity of metal which is 20 units
and it is growing exponentially at a rate of 17% for time x
So the required equation will be y=20 *e to the power x*17%
value of e is 2.718. so the equation becomes y=20(2.7)to power x

There are 10 2/15 kg of watermelons and coconuts on a truck. The weight of the watermelons is 3 3/5 times that of the coconuts. How heavy are the coconuts on the truck, in kg?
Answer:
2 7/76 kg
Step-by-step explanation:
Let the weight of
Watermelons = x
Coconut = y
There are 10 2/15 kg of watermelons and coconuts on a truck.
x + y = 10 2/15
x = 10 2/15 - y
x = 152/15 - y.... Equation 1
The weight of the watermelons is 3 3/5 times that of the coconuts.
x = 3 3/5 × y
x = 18/5 × y
x = 18y/5
How heavy are the coconuts on the truck, in kg?
Find y
We substitute 18y/5 for x in Equation 1
x = 152/15 - y
18y/5 = 152/15 - y
18y /5 + y = 152/15
Multiply through by 15
18y/5 × 15 + y × 15 = 152/15 × 15
3 × 18y + 15y = 152
54y + 15y = 152
69y = 152
y = 152/69
y = 2 14/152
y = 2 7/76 kg
Therefore, the weight of the coconuts are 2 7/76 kg

Find the area of the triangle below.
Be sure to include the correct unit in your answer.
m
4yd
14 yd
17 yd
To Find :
The area of triangle whose side are 4 yard, 14 yard and 17 yard.
Solution :
We will use Heron's formula to find area of the triangle.
So,
[tex]s = \dfrac{a+b+c}{2}\\\\s = \dfrac{4+14+17}{2}\\\\s = 17.5[/tex]
Now, heron's formula is :
[tex]A = \sqrt{s(s-a)(s-b)(s-c)}[/tex]
Putting all given values in above equation :
[tex]A = \sqrt{17.5\times (17.5-4)\times(17.5-14)\times(17.5-17)}\\\\A = \sqrt{17.5\times 13.5\times 3.5\times 0.5}\\\\A = 20.33\ yard^2[/tex]
Hence, this is the required solution.

The height of the square pyramid is 9.8 in.
Step-by-step explanation:
Given;
area of the square pyramid, A = 96 in²
base length, a = 4 in
height of the pyramid, h = x in
The surface area of the pyramid is calculated as follows;
[tex]SA = a^2 + 2a \sqrt{\frac{a^2}{4} + h^2} \\\\96 = 4^2 + 2(4)\sqrt{\frac{4^2}{4}+ x^2} \\\\96 = 16 + 8\sqrt{4+ x^2} \\\\96-16 = 8\sqrt{4+ x^2}\\\\80 = 8\sqrt{4+ x^2}\\\\\frac{80}{8} = \sqrt{4+ x^2}\\\\10 =\sqrt{4+ x^2}\\\\ (10)^2 = 4+ x^2\\\\100 = 4 + x^2\\\\ x^2 = 100-4\\\\x^2 = 96\\\\x = \sqrt{96} \\\\x = 9.80 \ in[/tex]
Therefore, the height of the square pyramid is 9.8 in.

Find the lateral area and surface area of a cone with a radius of 12 and a height of 21
Answer:
The Lateral Surface Area is 911.32 square unit and
Total Surface Area is 1361.7 square unit.
Step-by-step explanation:
For a given Cone
Radius (r) = 12
Height (h) = 21
For Lateral Surface Area
Formula:A = πr√r² + h²
A = 3.14 × 12 × √(12)² + (21)²
A = 3.14 × 12 × √144 + 441
A = 3.14 × 12 × √585
A = 37.68 × 24.18
A = 911.32 square unit
Now,
For Total Surface Area
Formula:A = πrl + πr²
For Slant height (l)
l² = r² + h²
l² = (12)² + (21)²
l² = 144 + 441
l² = 585
l = 24.18
So,
A = πrl + πr²
A = πr(l + r)
A = 3.14 × 12 × (24.14 + 12)
A = 3.14 × 12 × 36.14
A = 1361.7 square unit
Thus, The Lateral Surface Area is 911.32 square unit and Total Surface Area is 1361.7 square unit.

Can I have the slope and y intercept for 2y - 4x - 10 =0
Answer:
Slope = 2, Y-intercept = (0, 5)
Step-by-step explanation:
First, isolate y by moving all other terms to the other side of the equation.
2y - 4x - 10 = 0 ⇒ 2y = 4x + 10 ⇒ y = 2x + 5
The coefficient next to the x tells you the slope and the constant on the end tells you the y-intercept.
Therefore, the slope is 2 and the y-intercept is (0, 5).
Answer:
slope=2 ,y-intercept=5
Step-by-step explanation:
2y-4x-10=0
2y=4x+10+0
2y=4x+10 . divide both sides by 2
y=2x+5

Answer:
Gross pay when she works 46 hours a week = 532 dollars per week
Step-by-step explanation:
Complete question
Find gross pay when she works 46 hours a week
Solution
For working hours less than or equal to 40 hours, kim earns 10.90 per hour
For working hours higher than the basic 40 hours of working, the per hour rate increases by 1.5 time = 1.5 *10.90 = 16 dollars per hour
Gross pay for 46 working hours = 40 *10.90 + 6*16 = 532 dollars per week

Function g can be thought of as a translated (shifted) version of f(x)=x^2 Write the equation for g(x),
Answer:
g(x) = (x - a)² or
g(x) = (x + a)² or
g(x) = x² + a or
g(x) = (x + b)² + a or
g(x) = (x + b)² - a or
g(x) = (x - b)² + a or
g(x) = (x - b)² - a
Step-by-step explanation:
Given equation:
f(x) = x²
This is the equation of a parabola with turning points at (0,0) facing up.
Now;
g(x) which is a shifted version of f(x) will have one of many forms depending on the nature of translation.
If f(x) = x² is shifted to the right by a units, then;
g(x) = (x - a)²
If f(x) = x² is shifted to the left by a units, then;
g(x) = (x + a)²
If f(x) = x² is shifted upwards by a units, then;
g(x) = x² + a
If f(x) = x² is shifted downwards by a units, then;
g(x) = x² - a
If f(x) = x² is shifted upwards by a units and to the left by b units, then;
g(x) = (x + b)² + a
If f(x) = x² is shifted downwards by a units and to the left by b units, then;
g(x) = (x + b)² - a
If f(x) = x² is shifted upwards by a units and to the right by b units, then;
g(x) = (x - b)² + a
If f(x) = x² is shifted downwards by a units and to the right by b units, then;
g(x) = (x - b)² - a
What is the probability that a group of five friends all have different birthdays? Show all of your work for full credit.
Answer: 0.98630136986
Step-by-step explanation:
There are 365 possible birthdays. The key to assigning the probability is to think in terms of complements: “Two (or more) people share a birthday” is the complement of “All people in the group have different birthdays.” Each probability is 1 minus the other. What is the probability that any two people have different birthdays? The first person could have any birthday (p = 365÷365 = 1), and the second person could then have any of the other 364 birthdays (p = 364÷365). Multiply those two and you have about 0.9973 as the probability that any two people have different birthdays, or 1−0.9973 = 0.0027 as the probability that they have the same birthday. If you have a group of five, it would mean your equation would have to be (p=360÷365)

Answer:
6 cm
Step-by-step explanation:
Well let me explain... It's saying that side AB has a length of 6 cm and side BC has a length of 10 cm. So we can already start labeling the sides with their given length and actually solve for AC.
Well we don't really got much to say about AC but what we do know is that side AB and AC are equivalent. Why? Cause when there's always a triangle that has two equal sides but one side bigger, the triangle is a isosceles.
So we can say that side AB is (Δ) from the top of the triangle all the way to the left corner (6 cm). Then side BC will be from the left corner to the right corner (10 cm) and side AC will be from the top to the right corner (6 cm).

what is the factor of x^2 + 2x - 3
Answer:
(x + 3)(x - 1)
Step-by-step explanation:
Given
x² + 2x - 3
Consider the factors of the constant term (- 3) which sum to give the coefficient of the x- term (+ 2)
The factors are + 3 and - 1 , since
3 × - 1 = - 3 and 3 - 1 = + 2 , then
x² + 2x - 3 = (x + 3)(x - 1) ← in factored form
What is the factor of x² + 2x - 3
Solution:-x² + 2x - 3[tex] \rightarrow [/tex] x² + 3x - x - 3 = 0
[tex] \rightarrow [/tex] x(x + 3) -1(x + 3) = 0
[tex] \rightarrow [/tex] (x + 3) (x - 1) = 0

Which line is perpendicular to 4y+3x=12?
A)3x+4y=8
B)y=-3x+8
C)y+4x=-3
D)8x-6y=18
Answer:
D) 8x - 6y = 18
Step-by-step explanation:
The general equation of a line is;
y = mx + c
m is the slope and c is the y-intercept
so for;
4y + 3x = 12
4y = -3x + 12
divide through by 4
y = -3/4x + 3
the slope here is -3/4
To get the other line, we divide -1 by the slope of the first line
This is because when two lines are perpendicular, the product of their slopes is -1
So the slope of the line we are looking for is -1 divide by -3/4 = 4/3
Let us take a look at option D
8x - 6y = 18
6y = 8x - 18
divide through by 2
3y = 4x - 9
divide through by 3
y = 4/3(x) - 3
So as we can see, we have our slope as 4/3 and this option is our answer

And:
[tex]a_{n+1}=-5a_n-1[/tex]
And we want to find:
