I have a circular piece of fabric I am going to make a tablecloth. The radius of the fabric is 2 meters. What is the area of the tablecloth I can make
Essentially, you are attempting to find the area of a circle with a radius of 2 meters.
The formula for an area of a circle is [tex]\pi r^2[/tex], or pi times radius squared.
Plugging in 2 meters as your radius, that gets your answer to be [tex]4\pi[/tex], or 12.57 in decimal.
Find the value of a4 for this geometric series (I’ll add you on discord if you solve my guy and guyetts)
Answer:
The value of a4 is 6
Step-by-step explanation:
* Lets revise the rule of the geometric series
- There is a constant ratio between each two consecutive numbers
- Ex:
# 5 , 10 , 20 , 40 , 80 , ………………………. (×2)
# 5000 , 1000 , 200 , 40 , …………………………(÷5)
* General term (nth term) of a Geometric series:
- a1 = a , a2 = ar , a3 = ar2 , a4 = ar3 , a5 = ar4
- an = ar^n-1, where a is the first term , r is the constant ratio
between each two consecutive terms and n is the position
of the number in the series
* Now lets solve the problem
- The rule of the series is 2/9 (3)^n - 1
∴ a = 2/9 and r = 3
- To find a4 put n = 4
∴ a4 = 2/9 (3)^(4 - 1) = 2/9 (3)³ = 2/9 (27) = 6
∴ The series is 2/9 , 2/3 , 2 , 6 , ........
* The value of a4 is 6

A person invests 9000 dollars in a bank. The bank pays 6% interest compounded monthly. To the nearest tenth of a year, how long must the person leave the money in the bank until it reaches 14000 dollars?
Answer:
[tex]7.4\ years[/tex]
Step-by-step explanation:
we know that
The compound interest formula is equal to
[tex]A=P(1+\frac{r}{n})^{nt}[/tex]
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
n is the number of times interest is compounded per year
in this problem we have
[tex]t=?\ years\\ P=\$9,000\\ r=0.06\\n=12\\ A=\$14,000[/tex]
substitute in the formula above
[tex]14,000=9,000(1+\frac{0.06}{12})^{12t}[/tex]
[tex](14/9)=(1.005)^{12t}[/tex]
Apply log both sides
[tex]log(14/9)=(12t)log(1.005)[/tex]
[tex]t=log(14/9)/[(12)log(1.005)][/tex]
[tex]t=7.4\ years[/tex]
The exponential function, f(x) = 2^x, undergoes two transformations to g(x) = 1/3 x 2^x - 7. how does the graph change? select all that apply. A. It is vertically compressed. B. It is vertically stretched. C. It is shifted right. D. It is shifted down E. It is lipped over the x-axis.
Answer:
A and D
Step-by-step explanation:
Since a (1/3) is less than 1, it is vertically compressed. The -7 is outside of the parenthesis so it is shifting down.
Answer:
options A and D are the correct options.
Step-by-step explanation:
The parent exponential function is f(x) = 2ˣ
Now this function undergoes two transformations to form g(x) = [tex]\frac{1}{3}(2^{x})-7[/tex]
When parent function f(x) = 2ˣ is multiplied by [tex]\frac{1}{3}[/tex], this means f(x) has been compressed vertically because [tex]\frac{1}{3}[/tex] < 1.
Now we subtract 7 from the new function [tex]\frac{1}{3}[/tex] [tex](2^{x})[/tex], that means we are shifting this function 7 units downwards on y-axis.
Therefore, options A and D are the correct options.
What is the solution for the following system of linear equations? Give your answer in the form of an ordered pair.
3x + 2y = 5
4x − 9y = −5
Giving brainliest + 30 points!
Answer:
(1,1)
Step-by-step explanation:
3x + 2y = 5
4x − 9y = −5
Multiply the first equation by 4 and the second equation by -3 so we can eliminate x
4(3x + 2y) = 5 *4
Distribute
12x +8y = 20
-3(4x − 9y) = −5*-3
-12x +27y = 15
Add the two new equations together
12x +8y = 20
-12x +27y = 15
------------------------
35y = 35
Divide by 35
35y/35 = 35/35
y=1
Now we can find x
3x+2y =5
3x+2(1) =5
3x +2 =5
Subtract 2 from each side
3x+2-2=5-2
3x=3
Divide by 3
3x/3 = 3/3
x=1

What is the area of the following trapezoid?

The area of a trapezoid is [tex]\frac{a+b}{2} h[/tex] so substitute the values.
[tex]\frac{14 + 28}{2} 10[/tex] → [tex]\frac{42}{2} 10[/tex] → 21 * 10 → 210mm²
Hope this helps!!
The area of the following trapezoid is 210mm².
How to calculate the area of a trapezoid?The area of a trapezoid can be calculated if the length of its parallel sides and the perpendicular distance (height) between them is given. The formula for the area of a trapezoid is expressed as,
Area = {(a + b) × h} / 2
Where a and b are the parallel sides and h is the height in the figure below.
In the given question we have, a = 14 mm , b = 28 mm and h = 10 mm.
So, by using the formula for finding the area of a trapezoid,
Area = {(14 + 28) × 10} / 2
= {42 × 10 } / 2
= 420 / 2
= 210
The unit of the area is mm².
Therefore, the area of the following trapezoid is 210 mm².

Answer:

The coordinates of the midpoint of the line segment that has endpoints (2,3) and (10,3) are (6,3).
What are the coordinates of the midpoint of the line segment AB?Suppose we've two endpoints of a line segment as A(p,q), and B(m,n), then let the midpoint be M(x,y) on that line segment. Then, its coordinates are x =(p+m)/2 and y = (q+n)/2.
Given the endpoints of the line segment are A(-3,4) and B(-6,-1), then the coordinates of the midpoint will be,
x = (2+10)/2 = 12/2 = 6
y = (3+3)/2 = 6/2 = 3
Hence, the coordinates of the midpoint of the line segment that has endpoints (2,3) and (10,3) are (6,3).

What is the area of the irregular figure below?
36
48
144
288
Answer:
36
Step-by-step explanation:
This figure is a trapeoid.
Turning the figure sideways,
A = 1/2 (b1+b2) *h where b1 and b2 are the top and bottom and h is the height
b1 and b2 are the top and bottom so b1 =6 and b2=12 and h is the height so h = 4
A = 1/2 (6+12)*4
A = 1/2 (18)*4
= 9*4
= 36 in^2
The area of the irregular figure is 36 sq. in.
Given is an irregular figure with dimensions 6 in, 4 in and 12 in, we need to find the area of the irregular figure,
To find the area of the given figure, we will break the figure into two regular figures,
a) Triangle [base = 4 in and height = 12-6 = 6 in]
b) Parallelogram [base = 4 in and height = 6 in]
Area of a triangle = 1/2 × base × height
Area of a parallelogram = base × height
Therefore,
Area of the irregular figure = [1/2 × 4 × 12] + 4 × 6
= 24 + 12
= 36
Hence the area of the given figure is 36 in².

Which has a greater volume; two regular cans of soup, each with a diameter of 8 cm and a height of 10 cm or one family size can of soup, which has a diameter of 10 cm and a heigh if 12 can? Explain and give your calculations.
Answer:
The two regular cans of soup has a greater volume than the family size can of soup
Step-by-step explanation:
step 1
Find the volume of two regular cans of soup, each with a diameter of 8 cm and a height of 10 cm
The volume is equal to
[tex]V=2[\pi r^{2} h][/tex]
we have
[tex]r=8/2=4\ cm[/tex] ----> the radius is half the diameter
[tex]h=10\ cm[/tex]
substitute
[tex]V=2[\pi (4)^{2} (10)][/tex]
[tex]V=320\pi\ cm^{3}[/tex]
step 2
Find the volume of one family can of soup, with a diameter of 10 cm and a height of 12 cm
The volume is equal to
[tex]V=\pi r^{2} h[/tex]
we have
[tex]r=10/2=5\ cm[/tex] ----> the radius is half the diameter
[tex]h=12\ cm[/tex]
substitute
[tex]V=\pi (5)^{2} (12)[/tex]
[tex]V=300\pi\ cm^{3}[/tex]
therefore
Compare the volumes
[tex]320\pi\ cm^{3} > 300\pi\ cm^{3}[/tex]

philip ask julie to pick a number at random from 1 to 100, and then asks shelly to do the same. what is the probability that both will select 49? show your work
Answer:
[tex]\frac{1}{10000}[/tex]
Step-by-step explanation:
In probability, "AND" means Multiplication
"OR" means addition
There are 100 numbers from 1 to 100. Probability of picking 49 is 1/100 (since we want 1 specific number form 100 numbers).
Question is asking Probability that Phillip selects 49 AND ALSO Shelly select 49. since there is "AND", we just multiply both the probabilities of Phillip and Shelly.
[tex]\frac{1}{100}*\frac{1}{100}=\frac{1}{10000}[/tex]

y= x/2 is the same as y= 1/2 * x + 0 (this is now in the form y= mx +b.)
y= x+ 2 is already in (y=mx+b) form, with m being 1.
now what you can do is look at the individual parts of these equations.
the b is the y intercept. So when x is 0, y is b. in the y= 1/2 x + 0 equation, we know when x= 0, y= 0.
for the y=x + 2, we know that when x= 0, y= 2. Since this is not a point on the line shown, we know that it is not correct. Therefore, your answer would be y= 1/2 x, or y= x/2.
You could also find this using slope, but the y- intercept (b) was simpler to explain and find. :)

Find the perimeter.
Find the area.
Find the perimeter and area if x=5.
Answer:
perimeter = 10x + 2
area = 6x^2 + 2x
perimeter = 52
area = 160
Step-by-step explanation:
perimeter = 2 * length + 2 * width
perimeter = 2(3x + 1) + 2(2x)
perimeter = 6x + 2 + 4x
perimeter = 10x + 2
area = length * width
area = (3x + 1)(2x)
area = (2x)(3x + 1)
area = 6x^2 + 2x
For x = 5:
perimeter = 10x + 2 = 10(5) + 2 = 50 + 2 = 52
area = 6x^2 + 2x = 6(5^2) + 2(5) = 6(25) + 10 = 150 + 10 = 160
