Answer: 26.93 square inches
Step-by-step explanation:
first let us find the area of the rectangle shape
rectangle area = length times width
rectangle area = 2 times 11
rectangle area = 22 inches
now let us do the half circle area
half circle area = 1/2(πr^2)
half circle area ~ 1/2 times 3.14(1)^2
half circle area ~ 1/2 times 3.14^2
half circle area ~ 1/2 times 9.8596
half circle area ~ 4.9298
now let’s add the half circle area and the rectangle area to get our total area
total area ~ 4.9298 + 22
total area ~ 26.9298
total area ~ 26.93
26.93 square inches is the total area rounded to the nearest hundredth.
The top of a rectangular table has an area of 11 square feet. It has a length that is 3.5 feet more than the width. Find the dimensions of the table top.
The length of the table is ____ feet and the width of the table is ____ feet.
Step-by-step explanation:
If we let the width be w, then the length is w+3.5.
This means that w(w+3.5)=11
w^2 + 3.5w - 11 = 0
2w^2 + 7w - 22 = 0 (multiply both sides by 2)
(2w+11)(w-2)=0
w = -11/2 or w = 2 (disregard w = -11/2 as distance is positive)
This means that w=2, and thus the length is 2+3.5=5.5

what is 4 over 10 plus 88 over 100
Answer:
1.28
Step-by-step explanation:
4/10 + 88/100
so this is unlike denominators so
4 times 10 and 10 times 10 equal to 40/100
so 40/100 + 88/100 equal to 128/100 so we simplify 128÷2 and 100÷2 equal to 64/50 and 64÷2 and 50÷2 equals 32/25 we do long division then it is equal to 1.28

The value of a company’s stock is represented by the expression x2 – 2y and the company’s purchases are modeled by 2x + 5y. The company’s goal is to maintain a stock value of at least $6,000, while keeping the purchases below $2,000. Which system of inequalities represents this scenario?
A.) x2 – 2y ≥ 6000
2x + 5y < 2000
b.) x2 – 2y > 6000
2x + 5y < 2000
C.) x2 – 2y > 6000
2x + 5y ≤ 2000
D.) x2 – 2y ≤ 6000
2x + 5y ≤ 2000
Answer:
the answer is A
Step-by-step explanation:
Given x2-2y= stock value
and
2x+5y= purchases
stock value must stay at or more than 6000
while purchases must stay under 2000

A -4

no
-- 9
Answer:
x = - 43.5
Step-by-step explanation:
Step 1 : Simplify the given equation.
(8x - 20) - 16 = 10x + 51
8x - 20 - 16 = 10x + 51
8x - 36 = 10x + 51
Step 2 : Add/Subtract the alphabetical terms and numerical terms separately.
8x - 36 = 10x + 51
Step 3 : Add 36 on both sides.
8x = 10x + 51 + 36
8x = 10x + 87
Step 4 : Subtract 10x on both sides.
8x - 10x = 87
- 2x = 87
Step 5 : Divide - 2 on both sides.
x = 87/-2
x = - 87/2 (answer in terms of fraction)
x = - 43.5 (answer in terms of decimal)
Hence,
The value of x is - 43.5

Part B Write an expression to find how many rolls of wallpaper Jackie needs to buy. Show the steps you used to evaluate the expression.
A. The rolls of groovy wallpaper is needed to cover the apartment bedroom. 9 rolls
B.The cost to re-wallpaper the apartment room $143.10
What is the cost?Based on the question, we have to assume there are no windows and no doors in that bedroom... to calculate how much less wallpaper we really need, and we cover completely from the floor to the ceiling.
A. If one rolls covers 50 sq ft, how many rolls do we need?
First, let's calculate the perimeter of that room, which is 16'x10'.
P = 16 + 10 + 16 + 10 = 52 feet of perimeter.
Now, the walls are 8 feet high... so, let's see just how big is the area to cover.
A = 52 feet * 8 feet = 416 sq feet to cover all walls.
Since we know each roll covers 50 sq ft, we will need:
416 / 50 = 8.32 rolls.
When talking about quantity you need to buy or to fill something, you always have to round up to the next unit. Because you usually can't buy a portion of a unit and if you round it down, you'll miss material to cover your walls.
So, we will need 9 rolls.
B. Total cost, based on $15.90 per roll.
We already know we need 9 rolls... so how much will it cost us?
C = 9 * $15.90 = $143.10

The diagram shows the "-3" in the input oval pointing to "2" in the output oval.
Through similar steps, we have the input -2 map to the output 3. Also, the input 0 points to the output 5.
The input -5 should map to 0, but 0 isn't in the output list. So we ignore -5 in the input oval.

Consider the series 4 + 12 + 36 ... Find the sum of the first 9 terms.
Answer:
39364
Step-by-step explanation:
You can simplify the equation to make 4(1+3+9...) The nth term is therefore [tex]3^{n-1}[/tex] so u can substitute that into the equation so 4([tex]3^{n-1}+ 3^{n} + 3^{n+1}[/tex]..). This would simplify to 4([tex]3^0 +3+3^2[/tex]+[tex]3^3+3^4+3^5+3^6+3^7+3^8[/tex]). By simplifying this, you can make it so 4([tex]2^2+6^2+18^2+42^2+81^2[/tex]) = 4(4+36+324+2916+6561) =39364
Two functions are shown below.
f(x) = 1/2*2x
g(x) = 5x+2
What is the largest value of x for which f(x) = g(x)?
Answer:
x = 6
Step-by-step explanation:
As the function f(x) is an exponencial function, it will grow faster than g(x), that is a linear function.
For small values of x, we have that f(x) < g(x). For example:
f(1) = 1/2 * 2 = 1
g(1) = 5*1 + 2 = 7
f(2) = 1/2 * 4 = 2
g(2) = 5*2 + 4 = 14
So we just need to check some integer values and see when f(x) will be bigger than g(x). It will not be a big value, as the exponencial function grows very fast.
For x = 5, we have:
f(5) = 1/2 * 32 = 16
g(5) = 5*5 + 4 = 29
For x = 6, we have:
f(6) = 1/2 * 64 = 32
g(6) = 5*6 + 4 = 34
For x = 7, we have:
f(7) = 1/2 * 128 = 64
g(7) = 5*7 + 4 = 39
So the largest integer value of x for f(x) ≤ g(x) is x = 6.
Another way to solve this is by plotting both equations, and then checking where they cross, that is, where f(x) = g(x).
Answer:
x = 6
Step-by-step explanation:
We assume your functions are ...
f(x) = (1/2)(2^x)g(x) = 5x+2In general, mixed polynomial and exponential functions have no algebraic solution. That means we need to solve f(x) = g(x) using a table of values, or by graphing.
__
Attached is a graphical solution. It shows the largest value of x for which f(x) = g(x) is x=6.
Check: f(6) = 1/2(2^6) = 32 = g(6) = 5(6) +2
__
Additional comment
We can start with f(x) = g(x) and subtract g(x) from both sides of the equation. This gives ...
f(x) -g(x) = 0
Many graphing calculators readily identify the zeros of a function or expression. We have used that fact to find the two values of x where these functions are equal: ≈0.32 and 6.
For x>6, the exponential function increases without bound, so the graphs never cross again. Likewise, for x < -0.32, the linear function decreases without bound, so the graphs never cross again.
The lower value of x where the graphs cross is an irrational number near −0.319886722135.

Which of the following is the maximum value of the equation y = −x2 − x + 6?
Step-by-step explanation:
f(x) = y= -x²-x+6
When y is max, f'(x) = 0
f'(x) = -2x-1
Equating to 0,
-2x-1= 0
x= -1/2
Put the value of x in f(x)
y = -(-1/2)² -(-1/2) +6
= -1/4+1/2+6
= 6+1/2
y= 13/2
