If g(x) = x² + 1, what is the value of g(-3)?
Answer:
g(-3)=10
Step-by-step explanation:
We want to find what g(x), or y is, when x is equal to -3.
g(x)== x² + 1
x= -3
Substitute -3 in for x.
g(-3)=(-3)²+1
Evaluate the exponent first. -3² is equivalent to -3*-3, which is equal to 9.
g(-3)=9+1
Add 9 and 1
g(-3)=10
Answer:
Step-by-step explanation:
g(x)=x^2+1
at g(-3) = (-3)^2+1
=9+1=10

Jessi sold half her comic books. Then, she bought 9 more. She now has 11 total. How many did she begin with?
Answer: she begin with 6.
Step-by-step explanation:
At the beggining she had A books.
She sold half of that, so now she has A/2 books.
She bought 9, so now she has A/2 + 9 books,
And we know that A/2 + 9 = 11 books
So A/2 = 11 - 9 = 3
A = 2*3 = 6
So she started with 6 books
Answer:
She began with 4 books
Step-by-step explanation:
Let the original number of Jessi Comic books be x
When She sold half of the comic books, she has ( x - x/2) = x/2 left
When she bought 9 more, she has 11 in total. That is, x/2 + 9 = 11
x/2 = 11 - 9
x/2 = 2
x = 2 * 2
x = 4
She began with 4 books
A hemisphere fake stone made of clay has a diameter of 16 inches. The density of clay is 0.0035 pounds per cubic inch. The clay is sold by one pound increments only and costs $4.59 per pound. How much would it cost to buy enough clay to make 8 complete hemisphere stones?
Answer:
$137.82
Step-by-step explanation:
The volume of a hemisphere stone is given by the volume of a half-sphere:
Volume = (2/3) * pi * radius^3
If the diameter is 16 inches, the radius is 16/2 = 8 inches, so the volume is:
Volume = (2/3) * pi * 8^3 = 1072.33 in3
We need a total of 8 stones, so the total volume is:
Total Volume = 8 * 1072.33 = 8578.64 in3
The density of clay is 0.0035 pounds per cubic inch, so the total weight of the 8 stones is:
Weight = Total Volume * density = 8578.63 * 0.0035 = 30.0252 pounds
Finally, if the price of each pound of clay if $4,59, the final price is:
Price = 30.0252 * 4.59 = $137.82

Answer:
540°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
A pentagon has n = 5, thus
sum = 180° × 3 = 540°

Answer:
[tex] 30\: m^2 [/tex]
Step-by-step explanation:
For triangle:
Base = (4 + 3 +1) m = 8 m
Height = 9 m
For rectangle:
Length = 3 m
width = 2 m
Area of shaded region = Area of triangle - Area of rectangle
[tex]= \frac{1}{2}\times base\times height-length \times width \\\\= \frac{1}{2} \times (4 + 3 + 1) \times 9 - 3 \times 2 \\ \\ = \frac{1}{2} \times 8 \times 9 - 6 \\ \\ = 4 \times 9 - 6 \\ = 36 - 6 \\ = 30 \: {m}^{2} [/tex]

Answer:
[tex]\frac{a}{1 +bc} = x[/tex]
Step-by-step explanation:
In this question, it appears that you need to solve this equation in terms of x.
Beginning with the equation a = x(1 + bc), we must isolate the 'x' variable and make an equation equivalent to 'x'. This can be done by:
a = x(1 + bc)
Divide (1 + bc) from both sides, giving you:
[tex]\frac{a}{1 +bc} = x[/tex]
What is -2/3 divided by 2 1/4=?
Answer:
-8/27
Step-by-step explanation:
Convert 2 1/4 into a improper fraction: 9/4
Rewrite the equation: -2/3 divided by 9/4
To divide fraction, multiply by the reciprocal of that fraction
Reciprocal of 9/4: 9/4
Multiply the fractions: -2/3 times 4/9
=-8/27
Answer:
-8/27
Step-by-step explanation:
-(2/3) ÷ (2 1/4 ) (convert 2 1/4 into improper fraction)
= -(2/3) ÷ (9/4) (convert ÷ to x by taking the reciprocal of 9/4)
= -(2/3) x (4/9)
= -(2 x 4) / (3 x 9)
= -8/27

What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
The equation is given below.
x + 40 + 55 = 180
Simplify the equation, then the value of 'x' is given as,
x + 40 + 55 = 180
x + 95 = 180
x = 180 - 95
x = 85
The value of the variable 'x' will be 85. Then the correct option is A.

The International Business Club starts the school year with $250.50 in their account. They spend $35 each month on activities. The Future Agricultural Leaders Club starts with $300 and spends $45.25 each month.
Answer:
250.5 - 35m = 300 - 45.25m
Complete question:
Which equation can be used to find m, the number of months it will take for both accounts to have the same amount of money?
250.5 + 35m = 300 + 45.25m
250.5 – 35m = 300 – 45.25m
250.5m – 35 = 300m – 45.25
250.5m + 35 = 300m + 45.25
Step-by-step explanation:
For The International Business Club: y = 250.50 - 35m,
For The Future Agricultural Leaders Club: y = 300 - 45.25m.
So the answer is 250.5 - 35m = 300 - 45.25m
250.5 – 35m = 300 – 45.25m
Explanation:
It's this one because the initial for international Business Club is $250.50 and their monthly spending is $35, and for Future Agricultural Leaders Club their initial is $300 and their monthly spending is $45.25
So, the equation would be 250.5 – 35m = 300 – 45.25m
