Answer 1

Answer:

a = 4[tex]\sqrt{5}[/tex]

Step-by-step explanation:

pythagorean theorem:

a² + 8² = 12²

a² + 64 = 144

a² = 80

a = [tex]\sqrt{80}[/tex]

a = [tex]\sqrt{4}[/tex]·[tex]\sqrt{4}[/tex]·[tex]\sqrt{5}[/tex] which simplifies to be 4[tex]\sqrt{5}[/tex]

An investment made in the stock market decreased at a rate of 12% per year for 25 years . What is the current value of the 100,000 investment? Include your calculations in your final answer

Answers

Answer:$73947.52

Step-by-step explanation:

The investment decreases in value, so the common ratio r is (1.000-0.012), or 0.988. Thus, A = $100,000* (0.988) ^25 = $73947.52 is the current value, after 25 years.

Find the area of the shaded region

Answers

Answer:

Ok so what you should is first find the area for both of the circle

[tex]Area = \pi r^2\\[/tex]

Big circle

you are given the radius which 14mm

[tex]3,14(14)^2 = 615.44 mm^2[/tex]

Small circle

you are given the diameter of the small circle which 14mm

radius = diameter/2

14/2=7mm

[tex]3.14(7)^2 = 153,86mm^2[/tex]

Shaded area means the difference between the 2 areas, in my opinion

so you do 615.44 - 153.86 = 461.58 mm^2

a) 15%

b) 50%

c) 30%

d) 60%

Jeevan buys a bike for Rs 200000. At the end of 1 year, the value of the bike has depreciated by 15 percent.How much is the bike now worth?​

Answers

Answer:

Rs.170000

Step-by-step explanation:

Given data

Cost price of bike= Rs 200000

Time= 1 year

Rate of depreciation= 15%

Let us apply the formula for depreciation

A=P(1-r)^t

A= 200000(1-0.15)^1

A= 200000(0.85)^1

A= 200000*(0.85)^1

A= 200000*(0.85)

A=Rs.170000

Hence the value of the bike will be Rs.170000

Kelly had 13 cups of strawerries. She wants to divide the strawberries into small daily servings. How many 1/3 cup servings are in the 13 cups of strawberries?

Answers

Answer:

Number of servings in 13 cups strawberries = 39

Step-by-step explanation:

Total amount of strawberries Kelly has = 13 cups

Amount of strawberries Kelly used in one serving = [tex]\frac{1}{3}[/tex] cups

Number of servings in 13 cups of strawberries = [tex]\frac{\text{Total amount of strawberries with Kelly}}{\text{Strawberries required in one serving}}[/tex]

= [tex]\frac{13}{\frac{1}{3}}[/tex]

= [tex]13\times \frac{13}{1}[/tex]

= 39

Therefore, number of servings in 13 cups strawberries = 39

If function f is the parent exponential function , what is the equation of transformed function g in terms of function f?

Replace the value of a to complete the equation.

Answers

Answer:

This problem is acually really simple.

Step-by-step explanation:

all you have to do is replace the a with a 3. SO It would look like this:

g(x)=3f(x)

hope this helps :)

The equation of the function g(x) is g(x) = 3f(x) or g(x) = 3e^x

How to determine the equation of g(x)?

The function f(x) is given as:

f(x)= e^x

The function is stretched by a factor of 3 to get the function g(x)

This means that:

g(x) = 3 * f(x)

Evaluate the product

g(x) = 3f(x)

Hence, the equation of the function g(x) is g(x) = 3f(x) or g(x) = 3e^x

Please explain this question in some simple language.

Answers

Answer:

Below.

Step-by-step explanation:

I can't see the words on your image very well but I can give you an explanation of the remainder theorem.

The theorem allows you to find the remainder of a division without doing the division itself.

You can find the remainder when  a polynomial is divided by a linear expression like 3x - 2, for example,  using this theorem.

An example will explain the method:

What is the remainder when x^3 - x^2 - 2x - 5 is divided by 2x - 1?

Put 2x - 1 = 0, this gives x = 0.5.

Now we plug x = 0.5 into the polynomial:

This = (0.5)^3 - (0.5)^2 -2(0.5) - 5 = -6.125

So the remainder is -6.125.

The formal definition is

The remainder when P(x) is divided by x - a is f(a).
