Answer:
[tex]f(x)=32(1.3)^x[/tex]
Step-by-step explanation:
Here, the growth factor is 1.3 since 32(1.3)=41.6, 41.6(1.3)=54.08, and so on.
Therefore, the function that represents the table is [tex]f(x)=32(1.3)^x[/tex]

Answers
Answer:
1) X + 234 = 633
2) t = 63
3) x = 12
Step-by-step explanation:
1 is simple subtraction, just subtract the whole by the number that is given. Then that will fill X.
2 is multiplication. If a variable is (for example, x) next to a number that means it is multiplying it by a hidden number. To find that, you multiply the number next to the variable. If the sum matches the solution, there you go.

A bag contains 4 red marbles, 3 blue marbles and 6 green marbles. If two marbles are
drawn out of the bag, what is the probability, to the nearest 1000th, that both
marbles drawn will be red?
Answers
Answer:
~0.143
Step-by-step explanation:
So, in total there are 15 marbles, and only 6 of them are red. So the first draw will have a chance of being red. Since you didn't mention placing it back, the next draw will have a chance of being red. It's , because you just took a red one out of the bag (leaving 5 left) and the total was lessened by one. To get the answer, you'd multiply both numbers together.
6/15 x 5/14 = 1/7 or (roughly) 0.143
which expression is equivalent to 12^-5 times 12^9?
a. 1/12^-45
b. 12^-45
c. 1/12^4
d. 1/12^-4
Answers
Answer:
D. 1/12^-4
Step-by-step explanation:
[tex]12^{-5}*12^{9}[/tex]
Since both exponents have the same base, we can add the exponents to get:
[tex]12^{-5+9}=12^{4}[/tex]
We can cross out A and B since they multiplied the two exponents, therefore both answers are wrong.
Now, let's try C and D.
C is wrong because it has a different base being raised to the same power.
D is correct. When you have a negative exponent, it is equivalent to the reciprocal of the base to the positive exponent.
The reciprocal of 1/12 is 12, and the positive of -4 is 4, therefore the answer is D.
Answer:
12^14
Step-by-step explanation:
It's the correct answer
I’m confused, mostly on 4. How can you prove it, and are they parallel?
Answers
Answer:
It is parallel and yes you can prove it.
Step-by-step explanation:
I would use a tool that you can use to figure out the angle, check all the corners and if the smaller one are the same and the wider corners are the same then then would be parallel. That only works though if there was a line going through like your problems. If you had a graph it would be easier.

What is the equation of this line?
y= 2x - 3
y= -1/2x- 3
y= -2x - 3
y= 1/2x - 3
Answers
Answer:
First option) y= 2x - 3
Step-by-step explanation:
[] The y-intercept, our b, is -3. This does not rule out any of the options as they all have -3.
[] The slope, when we have a graph with clear points, can be found with rise-over-run. We will pick a point and then count up and over to the next point.
-> Starting at the y-intercept, (0, 3), we count up 2 and to the right 1 for a slope of 2/1. This simplifies to 2.
[] Our equation is y = 2x - 3

What is the quadratic equation whose roots are 2 and 6, and whose leading coefficient is 5
Answers
Answer:
5x^2-8x + 12
Step-by-step explanation:
the formula for finding roots of equation is
x^2- (sum of roots)x + products of roots =0
and we already have the roots of the equation
so we add them to give 8
and multiply to give 12
hence the quadratic equation that has those roots with leading coefficient is 5x^2-8x + 12=0

Add or subtract each fraction
2 + 15/8
Answers
Answer:
3 7/8
Step-by-step explanation:
2 + 15/8 = 2/1 + 15/8
Let's add 2/1 + 15/8 like this:
2/1 × 8/8 = 16/8
16/8 + 15/8 = 31/8
Since that is an improper fraction, we will simplify it.
31/8 = 3 7/8
-6= -15r+9s. Solve for s
Answers
Answer:
(5r-2)/3 = s
Step-by-step explanation:
-6= -15r+9s
Add 15r to each side
-6+15r= -15r+15r+9s
15r-6 = 9s
Divide each side by 9
(15r-6)/9 = 9s/9
(5r-2)/3 = s
1. The sum of two numbers is 20.5. Their
difference is 6.5. Find the two numbers.
Answers
Answer:
13.5 and 7
Step-by-step explanation:
x + y = 20.5
× - y = 6.5
Hence,
x =20.5 - y
20.5 - 2y = 6.5
Hence,
2y = 14
and x = 20.5 - 20.5 - 7 = 13.5
Hope that helps :))
Answer:
The two numbers are 7 and 13.5
Step-by-step explanation:
Let the two numbers be x and y
Make 3 equations (for system of equation and substitution method)
Equation 1. x - y = 6.5
Equation 2. x = 6.5 + y
Equation 3. x + y = 20.5
Use the value of x in equation 2 to substitute x in equation 3.
6.5 + y + y = 20.5
Combine like terms
6.5 + 2y = 20.5
- 6.5 on both sides
2y = 14
Divide both sides by 2 to isolate y
y = 7
Substitute y in equation 3 to find x
x + 7 = 20.5
x = 13.5
Hope this helps :)

help find area pls :(
Answers
Answer:
Total area = 26.13 ft²
Step-by-step explanation:
area of a triangle = 1/2 x base x height
From inspection, the base of the triangle = 3 x 2 = 6
and the height of the triangle = 4
⇒ area = 1/2 x 6 x 4 = 12 ft²
area of a semicircle = [tex]\frac{1}{2}\pi r^2[/tex]
⇒ area = [tex]\frac{1}{2} \times 3.14 \times 3^2[/tex]
⇒ area = 14.13 ft²
Total area = 12 + 14.13 = 26.13 ft²

Answer:
78/100 or 39/50 (simplified)
Step-by-step explanation:
First, let's convert 78% into a decimal.
78% = 0.78Now, we know that 0.78 is the same thing as 78/100. We can simplify 78/100 into 39/50, where 2 is the GCF
Thus, the answer is 78/100 or 39/50.
