Step-by-step explanation:
If 3.25m is equal to 15kg then what about 1m?
3.25m = 15kg
1m =?
Then by cross multiplication we get 4.615 kg

Actually Welcome to the concept of expo functions.
f(x) = -8(2)^x - 12 ,
for f(0) ,here substitute x = 0
so we get as ,
==> f(0) = -8(2)^0 -12
==> f(0) = -8-12
==> f(0) = -20
hence, f(0) = -20
Answer:
Step-by-step explanation:
If it went from f(x) ⟹ f(0), that means that x=0.
So, you would plug in 0 for x in f(x)=-8(2)^x-12.
After plugging in the value of x, x=0, into the equation, you should have
f(0)=8(2)^0-12
Now, we are solving for f(0) (or f(x)).
You would use PEMDAS to solve this:
P-PARENTHESIS
E-EXPONENT
M-MULTIPLICATION
D-DIVISION
A-ADDITION
S-SUBTRACTION
There are no parenthesis
there are exponents,
(2)^0 and that =1
so we have f(0)=8(1)-12
there is multiplication, 8(1) which =8
so now we have f(0)=8-12
there is no division
there is subtraction
8-12, which equals -4
f(0)=-4
A polynomial has zeros x = 2, x = 0, X = 1, X = 2
What is the polynomial in factored form?
A) f(x) = x(x - 2)(x + 1)(x + 2)
B) f(x) = x(x + 2)(x-1)(x + 2)
C) f(x) = x2(x + 2)(x - 1)(x - 2)
D) f(x) = x(x + 2)(x - 1)(x - 2)
Answer:
f(x)= x(x+2)(x-1)(x-2)
Step-by-step explanation:
before taking the zeros each zeros were in the forrm
x+a=0 where 'a' is any number
then after taking the zeros, the zeros were in the form x=0 x=2 x=1
so we are gonna take then back to the form before taking the zeros
Ned and Jack are each saving money for a new smartphone. Ned initially has $65 and plans to save $5.50 per week. Jack does not have any money saved yet, but he plans to save $8.75 per week. Let x=# weeks and y=amount of money saved.
Answer:
I'm not sure exactly what you're looking but I would set up the equation like this.
y=65+5.5x for Ned's equation
y=8.75x for Jack's equation.
Step-by-step explanation:
This is in y=mx+b format, hopefully it helps!

Which name best describes the polygon with vertices (0, 0), (4, 8), (12, 8), and (16, 0)? A) Triangle C) Trapezoid B) Square D) Pentagon
Answer:
C) Trapezoid
Step-by-step explanation:
Given
[tex]A = (0,0)[/tex]
[tex]B = (4,8)[/tex]
[tex]C = (12,8)[/tex]
[tex]D=(16,0)[/tex]
Required
The possible shape
The above are 4 vertices.
Hence, the shape cannot be
(a) Triangle ---- it has 3 vertices
(b) Pentagon ---- it has 5 vertices
Calculate distance AB using distance formula
[tex]AB = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2[/tex]
Where:
[tex]A = (0,0)[/tex]
[tex]B = (4,8)[/tex]
[tex]AB = \sqrt{(0 - 4)^2 + (0 - 8)^2[/tex]
[tex]AB = \sqrt{( - 4)^2 + ( - 8)^2[/tex]
[tex]AB = \sqrt{16+64[/tex]
[tex]AB = \sqrt{80[/tex]
[tex]AB = 8.94[/tex]
Calculate distance BC using distance formula
[tex]BC = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2[/tex]
Where:
[tex]B = (4,8)[/tex]
[tex]C = (12,8)[/tex]
[tex]BC = \sqrt{(4 - 12)^2 + (8 - 8)^2[/tex]
[tex]BC = \sqrt{(-8)^2 + (0)^2[/tex]
[tex]BC = \sqrt{64 +0[/tex]
[tex]BC = \sqrt{64[/tex]
[tex]BC = 8[/tex]
Since
[tex]AB \ne BC[/tex]
Then, the polygon is not a square

A type of fish for your aquarium costs $8 each. You can spend at most $48. How many of these fish can you buy? Write an inequality to model the problem. Then solve the inequality to find the number of fish.
Answer:
x ≤ 6
Step-by-step explanation:
Cost of fish = $8
You can spend at most $48
How many of these fish can you buy?
Let
x = number of fishes you can buy
The inequality is
8x ≤ 48
Divide both sides by 8
x ≤ 48/8
x ≤ 6

You have 30 minutes to exercise at the gym. The Stairmaster burns 7 calories per minute, while the stationary bike burns 12 calories per minute. You want to burn 290 calories total using both machines. How much time should you spend on each machine?
Answer:
14 min on Stairmaster
16 min on Bike
Step-by-step explanation:
s = time on Stairmaster
b = time on bike
System of Equations:
s + b = 30
7s + 12b = 290
let 's' = 30-b
Substitution Method:
7(30-b) + 12b = 290
210 - 7b + 12b = 290
5b + 210 = 290
5b = 80
b = 16
s + 16 = 30
s = 14

If the length between points on a map is 6 inches, 8 inches, and 9 inches, and the scale is one inch equals 5 miles, find
the distances in miles
12.16 and 18 miles
11, 13 and 14 miles
30,40 and 45 miles
Given:
The length between points on a map is 6 inches, 8 inches, and 9 inches.
The scale is one inch equals 5 miles.
To find:
The distances in miles.
Solution:
The given scale is:
1 inch = 5 miles
Using this scale, we get
6 inches = 6 × 5 miles
= 30 miles
8 inches = 8 × 5 miles
= 40 miles
9 inches = 9 × 5 miles
= 45 miles
The distance is miles are 30, 40, 45 miles.
Therefore, the correct option is C.

Answer:
c = 3
Step-by-step explanation:
Given
[tex]\frac{2}{c-2}[/tex] - [tex]\frac{3}{c+2}[/tex] = [tex]\frac{7}{c^2-4}[/tex] ← factor the difference of squares
[tex]\frac{2}{c-2}[/tex] - [tex]\frac{3}{c+2}[/tex] = [tex]\frac{7}{(c-2)(c+2)}[/tex]
Multiply through by (c - 2)(c + 2) to clear the fractions
2(c + 2) - 3(c - 2) = 7 ← distribute and simplify left side
2c + 4 - 3c + 6 = 7
- c + 10 = 7 ( subtract 10 from both sides )
- c = - 3 ( multiply both sides by - 1 )
c = 3

10. Kate and Sophia are selling raffle tickets for a fundraiser.
Kate has sold 4 less than twice as many as Sophia.
If the two girls have sold a total of 38 tickets,
how many has each girl sold? equation and answer
Answer:
Sophie sold 14
Kate sold 24
Step-by-step explanation:
Kate has sold 4 less than twice as many as Sophia.
2s - 4
---------------------
sold a total of 38 tickets
Sophie + Kate = 38
s + (2s - 4) = 38
Combine like terms
3s - 4 = 38
Add 4 to both sides
3s = 42
Divide both sides by 3
s = 14
2s - 4 = 2*14 - 4 = 24
