A balloon has a radius of 7.25 cm. What is the approximate area of the circle, rounded to the nearest whole number?
Answer:
165 square cm
Step-by-step explanation:
Area of a circle is [tex]\pi r^2[/tex], where r = radius. We're given the radius as 7.25.
[tex]3.14 * 7.25^2[/tex] [tex]3.14 * 52.5625[/tex] [tex]165.04625[/tex] 165.04625 ≈ 165 square cmTherefore, the answer is 165 square cm.

Given the functions f(x)=7-2x and g(x)=5x-3 find g(f(-4)) find f(g(x))
Answer:
g(f(-4)) = -8
f(g(x)) = 13-10x
Step-by-step explanation:
g(f(-4)):
Plug in the equation f(x) into the variable x of g(x), we have:
[tex](gof)= 5(7-2x)-3[/tex]
Plug in x = -4 and the answer is -8
f(g(x)):
Plug in the equation g(x) into the variable x of f(x), we have:
[tex]7-2(5x-3) = 7-10x+6 = 13-10x[/tex]
How do you factorise 6x-9
Answer:
6 x a number - 9 = factored
In this case, since the number is not declared as a specific number, this is the key to us factoring.
Like the number could be 6. ↓
Factoring:
[tex]6*6-9=27\\6*3-9=9\\6*9-9=45[/tex]
bonus even factor:
[tex]6*2-9=3[/tex]
These are factors and Least common multiples of 6 and 9.
Because 9 and 3 show up during half of the problem, and these are related to 6 and 9, the parents, we could measure this on a mathematical scale that this proves the factors correct.
There are other ways to factor this. See comments.
The length of a rectangle is 11 m less than three times the width, and the area of the rectangle is 42 m^2 . Find the dimensions of the rectangle.
Given -
↠ the length of a rectangle is 11 m less than three times the width (let the width be x then length = 3x - 11)
↠the area of the rectangle is 42 m².
To find -
the dimensions of the rectangle.
Solution -
As we know,
area of rectangle = length × width
➟ 42 = (3x - 11) x
➟ 42 = 3x² - 11x
➟ 3x² - 11x - 42 = 0
now splitting the middle term to find the value of x,
➟ 3x² - (18 - 7)x - 42 = 0
➟ 3x² - 18x +7x - 42 = 0
➟ 3x (x- 6) +7(x - 6) = 0
➟ (3x + 7)(x - 6) = 0
➟ x = -7/3, 6
➟ x = 6
We will take the value of x as 6 because the value of dimensions can never be in negative.
Hence, length = 3 × 6 - 11 = 7 cm and width = 6 cm
arvin has a bake shop he sold 85 cakes today that is 16 cakes fewer than yesterday how many cakes did he sell yesterday
NEED SOLUTION EXPLAIN PLEASE
cake sold today :- 85
cake sold yesterday :- X
relationship between caked sold :-
Today cake sold = cake sold yesterday- 16 (ATQ)
85 = x -16
85+16= x = 101 cakes
so Arvin sold 101 cakes yesterday
Answer:
Its 101
Hope this will help you

Cake he sold today-85
Let the cake he sold yesterday be x,
x = 85+16
Therefore, x= 101
Therefore, He sold 101 cakes yesterday

-3x+3y=4 -x+y=3 substitution
Answer: No solution
Step-by-step explanation:
-3x+3y=4
-x+y=3
We will rewrite the first equation and then substitute it into the second equation since we are solving by substitution.
Rewriting
-3x + 3y = 4
3y = 4 + 3x
y = [tex]\frac{4}{3}[/tex] + x
Substituting
-x + y = 3
-x + ([tex]\frac{4}{3}[/tex] + x) = 3
-x + [tex]\frac{4}{3}[/tex] + x = 3
[tex]\frac{4}{3}[/tex] = 3

Find the exact value of y.
Answer:
[tex]y = 2\sqrt{10}[/tex]
Step-by-step explanation:
In left small right triangle: we have the square of left side = 5^2 + y^2 = 25 + y^2
In right small right triangle: we have the square of right side = 8^2 + y^2 = 64 + y^2
In the large right triangle, we have (25 + y^2) + (64 + y^2) = (5 + 8)^2
89 + 2y^2 = 13^2 = 169
2y^2 = 169 - 89 = 80
y = 80/2 = 40
so
[tex]y=\sqrt{40} = 2\sqrt{10}[/tex]

the slope goes by several names
• average rate of change
• rate of change
• deltaY over deltaX
• Δy over Δx
• rise over run
• gradient
• constant of proportionality
however, is the same cat wearing different costumes.
to get the slope of a straight line we only need two points off of it, hmmm let's use from the table (-1 , 13) and (2 , 1)
[tex](\stackrel{x_1}{-1}~,~\stackrel{y_1}{13})\qquad (\stackrel{x_2}{2}~,~\stackrel{y_2}{1}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{1}-\stackrel{y1}{13}}}{\underset{run} {\underset{x_2}{2}-\underset{x_1}{(-1)}}}\implies \cfrac{-12}{2+1}\implies \cfrac{-12}{3}\implies -4[/tex]
The required rate of change in the slope-intercept form is -4. Option A is correct.
What is the slope of the line?The slope of the line is the tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.
Here,
Two coordinates from the table,
(-2, 17) and (-1, 13)
Now,
Rate of change = slope of the function = (13 - 17) / (-1 - (-2))
= -4 / 1
= -4
Thus, the required rate of change in the slope-intercept form is -4. Option A is correct.

How to solve graph 5+h>7
Answer:
h > 2
Step-by-step explanation:
It may look hard, but it is not really.
1. Solve
Here we have the equation 5+h>7.
All we have to do to find h is to subtract 5 from both sides.
5+h>7
-5 -5
When you subtract 5 from both sides, you get
5 - 5 = 0
7 - 5 = 2
All is left is 0+h>2, or h > 2.
2. Substitute
To make sure, (I do this but you can if you want to) I will substitute.
The values of h have to be greater than 2. So, Let's substitute 3.
5 + h > 7 --> 5 + 3 > 7
It's simple math.
5+3=8
8>7
Now, also to confirm, let's try a value less than 2, 1.
5 + h > 7
5 + 1 > 7
6 > 7 is not true, so it is confirmed that anything less than 2 is not true and anything greater is true.
Hence, h > 2
Hope this helps :)

What is the slope of the line
-4+7= 2y - 3
Answer: 0
Step-by-step explanation:
Rewrite as y = mx + b form, where m is slope and b is the y-intercept.
2y - 3 = -4 + 7
2y = 3
y = 3/2
There is only the y- intercept, 3/2, therefore the slope is 0.

The value of x is 10.
What is Mean ?
Mean is the average value of the data, It depicts the central tendency of the data.
The numbers are 4 ,3,3,x
The Mean of the data is 5
The Mean = ( Sum of Data) / ( Number of Data)
Mean = (4+3+3+x ) / 4
5 = (10+x)/4
20 = 10+x
x = 10
Therefore, the value of x is 10.

1. The polynomial of degree 5, P(x) has leading coefficient 1, has roots of multiplicity 2 at x=1 and x=0 and a root of multiplicity 1 at x= -5 Find a possible formula for P(x)
The degree of the polynomial P(x) is the highest power of the polynomial P(X)
A possible formula for P(x) is [tex]P(x) =(x + 5)x^2(x - 1)^2 \\[/tex]
How to determine the polynomialThe given parameters are:
Roots of multiplicity 2 at x=1 and x=0
Root of multiplicity 1 at x= -5
Write out the roots
x=1 and x=0 ------- Multiplicity 2
x = -5 ------- Multiplicity 1
Equate the roots to 0
x - 1 = 0 and x = 0 ------- Multiplicity 2
x + 5= 0 ------- Multiplicity 1
Place the multiplicities as the exponents of the roots
(x - 1)^2 = 0 and x^2 = 0
(x + 5)^1 = 0
Multiply the expressions
[tex](x - 1)^2 * x^2 * (x + 5)^1 = 0 * 0 * 0[/tex]
This gives
[tex](x - 1)^2 * x^2 * (x + 5) = 0[/tex]
Rewrite as:
[tex](x + 5)x^2(x - 1)^2 = 0[/tex]
Replace 0 with P(x)
[tex]P(x) =(x + 5)x^2(x - 1)^2[/tex]
Hence, a possible formula for P(x) is [tex]P(x) =(x + 5)x^2(x - 1)^2 \\[/tex]
