suppose the function g(x) doubles the square of the input and then subtracts 13. what is g(3)?
Given:
The function [tex]g(x)[/tex] doubles the square of the input and then subtracts 13.
To find:
The value of [tex]g(3)[/tex].
Solution:
Let [tex]x[/tex] be the input value.
The square of the input is [tex]x^2[/tex].
Doubles the square of the input [tex]2x^2[/tex].
Doubles the square of the input and then subtracts 13, i.e., [tex]2x^2-13[/tex].
So, the function is:
[tex]g(x)=2x^2-13[/tex]
Putting [tex]x=3[/tex] in the above function, we get
[tex]g(3)=2(3)^2-13[/tex]
[tex]g(3)=2(9)-13[/tex]
[tex]g(3)=18-13[/tex]
[tex]g(3)=5[/tex]
Therefore, the value of [tex]g(3)[/tex] is 5.

Tommy types 54 words per minute, with an average of 3 mistakes. How many mistakes would you expect Tommy to make if he typed 300 words?
Answer:
around 17 mistakes
Step-by-step explanation:
We can write a ratio to solve
54 words 300 words
------------------ = -------------------
3 mistakes x mistakes
Using cross products
54x = 3*300
54x = 900
Divide by 54
54x/54 = 900/54
x =50/3
x = 16.66666666(repeating)
around 17 mistakes
X = mistakes in 300 words
54/3 = 300/X
54X = 3 x 300
X = 900/ 54
X = about 17 words, since 16 and 2/3 rounded to the nearest tenth is 17
Find the value of x.

if 5 hockey balls and 3 sticks cost $230.00 and 5 balls and 2 sticks cost $200 how much does one hockey ball cost?
step by step explanation:
Answer:
$28.
Step-by-step explanation:
We have the system of equations
5b + 3s = 230 (b = cost of 1 ball and s = cost of 1 stick).
5b + 2s = 200
Subtract the above from the first equation:
s = 30
So, substituting in equation 1:-
5b + 3(30) = 230
5b = 230 - 3(30) = 140
b = 28.
Checking in equation 2:-
5(28) + 2(30)
= 10 + 60
= 200.
- this checks out OK.
The cost of one hockey ball will be $28.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
The system of equations from the given data are:-
5b + 3s = 230 (b = cost of 1 ball and s = cost of 1 stick).
5b + 2s = 200
Subtract the above from the first equation:
s = 30
So, substituting in equation 1:-
5b + 3(30) = 230
5b = 230 - 3(30) = 140
b = 28.
Therefore, the cost of one hockey ball will be $28.

If a change dispenser contains 32 coins consisting of
only dimes and quarters worth $5.15, how many
dimes are in the dispenser?
=================================================
Work Shown:
d = number of dimes
q = 32-d = number of quarters
$5.15 = 515 cents
10d+25q = 515
10d+25(32-d) = 515
10d+800-25d = 515
-15d+800 = 515
-15d = 515-800
-15d = -285
d = -285/(-15)
d = 19
There are 19 dimes. You can stop here if you want.
q = 32-d = 32-19 = 13
There are 13 quarters
-------------------------------
Check:
1 dime = 10 cents
19 dimes = 19*10 = 190 cents
1 quarter = 25 cents
13 quarters = 13*25 = 325 cents
total value = 190 cents + 325 cents = 515 cents = $5.15
The answer is confirmed.

-72 + (-30) + 10 =
-72-30+10.
-72-30=-102
10-102 is also the same as
-102+10
The final answer is -92
Answer:
-92
Step-by-step explanation:
-72 + (-30) + 10 =
-72+ -30
Since they both have the same sign, add and then take the sign
72+30 = 102 and then take the negative sign
-102
-102+10
They have opposite signs, so we subtract and take the sign of the larger
102 -10 = 92
And 102 was negative so take the negative sign
-92

Solve for the radius using the pythagorean theorem:
a² + b² = c²
We know the lengths of the hypotenuse and one leg, so:
a = 12
b = ?
c = 16
Plug these into the equation:
12² + b² = 16²
Simplify:
144 + b² = 256
Subtract both sides by 144:
b² = 112
Take the square root:
b ≈ 10.6
Thus the radius is about 10.6 cm.
I am a 4 digit number all my digits are different they add up to 20 the hundred's digit is double than the one's digit
Answer:
- 2864
Step-by-step explanation:
Given that,
The number is of 4 digits
All are different
The sum of the 4 digits = 20
Hundred's digit is twice than one's digit
A.T.Q.
Let the unit digit be 4. So, the hundred's digit would be 4 * 2 = 8
Now, we have
_8_4
We know that the sum of four digits is 20. Thus,
_ + 8 + _ + 4 = 20
∵ _ + _ = 20 - 12 = 8
The possible numbers must make a sum of 8. Thus, one possibility can be 2 and 6.
Therefore, the number can be
2864
( 2 + 8 + 6 + 4 = 20)

The circumference of a circle is 6π m. What is the area, in square meters? Express your answer in terms of
π
π.
Answer:
9π meters
Step-by-step explanation:
SInce 6π is the circumference of the circle, 6π would be the diameter.
We need to then convert 6π into the radius which we can do by dividing 6π by 2 to get 3π.
The formula for the area of a circle is πr^2. Plug in the previous result for the radius to get the following:
π3^2
9π
Answer:
Area=9π m²
Step-by-step explanation:
Hi there!
We are given that the circumference of a circle is 6π meters, and we want to find the area of the circle
The formula to find the circumference of a circle is 2πr, where r is the radius
The formula to find the area of a circle is πr², where r is the radius
So we need to find the radius
As 6π and 2πr both equal the circumference of the circle, 6π is equal to 2πr. This is possible by a property known as transitivity (if a=b and b=c, then a=c) .
As an equation, the result is:
6π=2πr
Divide both sides by 2π
3=r
So the radius is 3 meters
Now, substitute 3 as the radius in πr² to find the area
A=πr²
A=π(3)²
Raise 3 to the second power, which is the same as multiplying it by itself
A=π*9
A=9π m²
Hope this helps!
