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
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.

The shape of a lateral face of a pyramid is always an isosceles triangle?
Answer:
No.
Step-by-step explanation:
Because the lateral faces of a regular pyramid are congruent isosceles triangles. The altitude of any of these triangles is the slant height of the regular pyramid.
Find the area of the shaded region
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
Hope that answers your question

Trinity asked a random sample of 50 students at her school if they brought lunch from home today. If 30 answered “yes,” about what percent of students at Trinity’s school brought lunch from home today?
a) 15%
b) 50%
c) 30%
d) 60%
Answer:
D
Step-by-step explanation:
60% of 50 equals 30
30% of 50 equals 15
15% of 50 equals 7.5
7.5% of 50 equals 3.75
3.75% of 50 equals 1.875

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?
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?
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
The general term of a sequence is given by Tn=-5n+6... which term in the sequence will be -269?

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.
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

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).

A set of data is described as:
The data is around 7. If another measurement were taken it would probably be around 7.
Which group of measures would lead to this conclusion? Think backwards to look at the sets of data that would give the results described above.
Range—4, Mode—6, Median—7, Mean—8
Range—5, Mode—9, Median—9, Mean—7
Range—12, Mode—9, Median—9, Mean—9
Range—10, Mode—7, Median—9, Mean—5
Answer:
B. Range - 5
Mode - 6
Median - 7
Mean - 8
step by step explaination:
if it's actually around 7, that's means 7 is equal to the median. And then, specifically, the mode & the mean number will side-to-side number of 7..which means number 6 and number 8.
