Answer:

1. y = 10(1/3)^x

2. 24.8 bacteria per minute

Step-by-step explanation:

1.

When you raise a number between 0 and 1 to a positive exponent, the result is less than 1, so it indicates exponential decay.

The only such function in the choices is

Answer: y = 10(1/3)^x

2.

b(t) = 4(2)^t

b(0) = 4(2)^0 = 4

b(5) = 4(2)^5 = 128

average rate of change = (128 - 4)/(5 - 0) = 124/5 = 24.8

Answer: 24.8 bacteria per minute

Answer:

Step-by-step explanation:

the area of the hemisphere is  1/2 \(\pi\)\(r^{2}\)

the radius is 1/2 the diameter,

the diameter is also the hypotenuse of the isosceles triangle

\(d^{2}\) = \(4^{2}\)+\(4^{2}\)

\(d^{2}\) = 32

d =\(\sqrt{32}\)

r = 1/2\(\sqrt{32}\)

1/2\(\pi\)(1/2\(\sqrt{32}\))^2

1/2\(\pi\)(1/4*32)

(32/8 )*\(\pi\)

4\(\pi\) ( the entire upper hemisphere )

area of the triangle is  1/2* 4 *4 = 8

then the exact area of the parts of the circle would be

4\(\pi\) - 8

Answer:

after working for at least 10 1/4 years

Step-by-step explanation:

After working for at least  10 1/4 years  a project manager would be eligible for a $20,000 monthly salary.

A quadratic equation, \(ax^{2} +bx+c=0\) is solved by

\(x=\frac{-b \pm \sqrt{b^2-4ac} }{2}\)

Given function \(f(x)=x^4-10x^2+10000\)

Function that has monthly salary $20,000 will be \(x^4-10x^2+10000=20000\)

\(x^4-10x^2+10000-20000=0\)

\(x^4-10x^2-10000=0\)

Now using the formula \(x=\frac{-b \pm \sqrt{b^2-4ac} }{2}\)

\(x^2=\frac{10 \pm \sqrt{10^2+40000} }{2}\)

\(x^2=\frac{10 \pm \sqrt{40100} }{2}\)

\(x^2=\frac{10 \pm 200.2}{2}\)

\(x^2=5 \pm 100.1\)

\(x^2=105.1\)

\(x=\sqrt{105.1}\)

\(x=10.25\)

Hence, after working for at least  10 1/4 years  a project manager would be eligible for a $20,000 monthly salary.

Answer:

analysis (i got to put a bunch of random stuff here cs the limit)

       A mathematical statement indicating an order relationship between two numbers or algebraic expressions, such as greater than, greater than or equal to, less than, or less than or equal to.

|x+1/3| < 3/2.

Consider the center of the group of numbers that fulfill 2|x+1/3|3 to be x = -1/3.

The maximum value of this set is obtained by adding 3/2 to this -1/3:

-1/3 + 3/2, or -2/6 + 9/6, or 7/6.

The bottom limit of this solution set is obtained by subtracting 3/2 from this and then -1/3:

-1/3 - 3/2, or -2/6 - 9/6, or - 11/6.

Answer:

Step-by-step explanation:

If Ben has 7 hours of lessons with Off Track Biking, we can find the total cost (C) using the formula:

C = 40h + 100

where h is the number of hours of lessons. Substituting h = 7, we get:

C = 40(7) + 100

C = 280 + 100

C = 380

Therefore, Ben pays $380 in total for his 7 hours of lessons with Off Track Biking.

The the speed of a car that travels the given distance in 5 seconds from the information is 65.6 mph.

Speed and time are two fundamental concepts in physics and mathematics that are often used together to describe the motion of objects.

Speed refers to how fast an object is moving, and is typically measured in units of distance per unit of time, such as meters per second (m/s) or miles per hour (mph). Speed can be either constant, meaning the object is moving at the same speed throughout its motion, or variable, meaning the object's speed changes over time.

Given that the speed R varies inversely with the time T

R = 41 mph T =  8 seconds

The distance can be calculated as( speed * time)

Distance = ( speed * time)

= 41 * 8 = 328miles

The total distance travel  can now bw seen as 328miles, the speed  of a car that travels the given distance in 5 seconds can now be calculated as

Speed =Distance / time.

= 328miles/ 5 seconds

= 65.6 mph.

Answer:

(-6, 8)

Step-by-step explanation:

a) The general solution is y = t^4/4 + t^2/2 + A, b) The general solution is y = t^5/20 + t^3/6 + At + B, c) the general solution is x = t^6/120 + t^4/24 + At^2/2 + Bt + C   d) The general solution is y = 3t^2/4 + t + A/2

(a) To find the general solution of y′=4t^3+t, we need to integrate both sides of the equation with respect to t. This gives us:
y = ∫(4t^3+t)dt = t^4/4 + t^2/2 + A
So the general solution is y = t^4/4 + t^2/2 + A, where A is the first constant of integration.

(b) To find the general solution of y′′=4t^3+t, we need to integrate both sides of the equation twice with respect to t. This gives us:

y′ = ∫(4t^3+t)dt = t^4/4 + t^2/2 + A
y = ∫(t^4/4 + t^2/2 + A)dt = t^5/20 + t^3/6 + At + B

So the general solution is y = t^5/20 + t^3/6 + At + B, where A is the first constant of integration and B is the second constant of integration.

(c) To find the general solution of d^3x/dt^3=4t^3+t, we need to integrate both sides of the equation three times with respect to t. This gives us:
d^2x/dt^2 = ∫(4t^3+t)dt = t^4/4 + t^2/2 + A
dx/dt = ∫(t^4/4 + t^2/2 + A)dt = t^5/20 + t^3/6 + At + B
x = ∫(t^5/20 + t^3/6 + At + B)dt = t^6/120 + t^4/24 + At^2/2 + Bt + C

So the general solution is x = t^6/120 + t^4/24 + At^2/2 + Bt + C, where A is the first constant of integration, B is the second constant of integration, and C is the third constant of integration.

(d) To find the general solution of 2y′=3t+2, we need to integrate both sides of the equation with respect to t. This gives us:

2y = ∫(3t+2)dt = 3t^2/2 + 2t + A
y = (3t^2/2 + 2t + A)/2 = 3t^2/4 + t + A/2

So the general solution is y = 3t^2/4 + t + A/2, where A is the first constant of integration.

Because the two angles are complementary, the value of x must be 11.5

In the image we can see that the two given angles are complementary, which means that their measures add up to 90°, then we can write:

(7x - 5)° + (x + 3)° = 90°

Now we can solve that linear equation to find the value of x, we iwll get:

7x + x - 5 + 3 = 90

8x - 2 = 90

8x = 92

x = 92/8

x = 11.5

Answer:

16π

Step-by-step explanation:

Given:

\(\text{Radius of circle}: 4 \ \text{m}\)

Formula:

\(\text{Area of circle} = \pi r^{2}\)

Replace the radius in the formula:

\(\implies \text{Area of circle} = \pi (4)^{2}\)

Evaluate the area:

\(\implies \text{Area of circle} = \pi (4)(4)\)

\(\implies \text{Area of circle} = 16\pi\)

Since the question says to determine the area in terms of π, the final answer is 16π.

We need to find the correct answer that makes the first fraction equivalent to that.

I am going to use process of elimination for this.

a) 6/1≠4/20 so this one is wrong (6/1 is 6 which ≠ 0.2)

b) 6/13≠4/20 so this one is wrong (6/1 is 0.46 which ≠ 0.2)

c)6/22≈4/20 so this one is almost right (6/22 is 0.27 which ≈ 0.2)

d) 6/30=4/20 this one is RIGHT!!! (0.2=0.2)

Based on the Triangle Inequality Theorem, any side of a triangle must be shorter than the sum of the other two sides.

Let a = first side, b = second side, and c = third side.

Applying the Triangle Inequality Theorem, we can say that:

Therefore, the measure of the third side must fall between 35 ft and 155 ft.

In the given arithmetic expression the value of x will be 3⁻⁸.

The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.

Given an Expression,

3² * x *3⁷ = 3

Simplifying the given arithmetic expression

3² * x *3⁷ = 3

In multiple, if the base is the same power will add up

x * 3²⁺⁷ = 3

x * 3⁹ = 3

Divided by 3⁹ into both sides

x = 3/3⁹
