Answer:
[tex]\displaystyle S_n=\sum_{k=1}^n{4(-3)^{k-1}}[/tex]
Step-by-step explanation:
The first term of this geometric series is 4. The common ratio is -12/4 = -3, so the general term is ...
an = 4·(-3)^(n-1)
The sum is the sum of terms of this form.
[tex]\displaystyle S_n=\sum_{k=1}^n{4(-3)^{k-1}}[/tex]

Use the graph to answer the question.
On a coordinate plane, a line goes from (negative 5, 7) to (3, 3).
Which parametric equations describe the curve?
x = –t + 1 and y = 0.5t + 4 when –2 ≤ t ≤ 6
x = –t + 1 and y = 0.5t + 4 when –5 ≤ t ≤ 3
x = 0.5t + 4 and y = –t + 1 when –2 ≤ t ≤ 6
x = 0.5t + 4 and y = –t + 1 when –5 ≤ t ≤ 3
The answer for this question is A:
A = x = –t + 1 and y = 0.5t + 4 when –2 ≤ t ≤ 6
The parametric equations of the curve are:
x = –t + 1 and y = 0.5t + 4 when –5 ≤ t ≤ 3
Parametric equation of the line:The parametric equation of the line is, [tex]x=x_0+at,y=y_0+bt[/tex] where [tex](x_0,y_0)[/tex] is the point on the line and [tex]\frac{b}{a}[/tex] is the slope of the line with a, b are real numbers.
Slope of the line:If (a, b) and (c, d) are any two points on the line then, slope of the line is:
m = (d - b)/(c - a)
For given situation,
a line goes from (-5, 7) to (3, 3).
Using the formula of slope, the value of m i.e., slope of the line would be,
⇒ m = (7 - 3)/(-5 - 3)
⇒ m = 4/(-8)
⇒ m = 1/(-2)
⇒ m= 0.5/(-1)
Comparing with m = b/a,
b = 0.5 and a = -1.
From the graph of the line given below,
A point (1, 4) is also on the line.
Let [tex]\bold{(x_0,y_0)=(1,4)}[/tex]
Using the parametric equation of the line,
[tex]x=x_0+at[/tex]
⇒ x = 1 + (-1)t
⇒ x = -t + 1
and [tex]y = y_0+bt[/tex]
⇒ y = 4 + (0.5)t
⇒ y = 0.5t + 4
Therefore, the parametric equations of the curve are:
x = –t + 1 and y = 0.5t + 4 when –5 ≤ t ≤ 3

mum puts the chicken in the oven at 4:25 p.m. she let it bake covered for 10 minutes, then uncovered for 35 minutes more. what time will the chicken come out of the oven?
Answer:
5:10 pm
Step-by-step explanation:
The chicken will come out of the oven at 5:10 p.m. after baking covered for 10 minutes and uncovered for 35 minutes at 4:25 p.m.
Use the concept of addition defined as:
In maths, addition is the process of adding two or more numbers together. The numbers being added are known as addends, while the outcome of the addition process, or the final response, is known as the sum.
Given that,
Mom places the bird in the oven at 4:25 p.m.
Chicken bakes covered for 10 minutes.
Chicken bakes uncovered for 35 minutes.
The objective is to determine the time when the chicken will be taken out of the oven.
If your mom puts the chicken in the oven at 4:25 p.m. and bakes it covered for 10 minutes,
Then add 10 minutes to the initial time,
So, the chicken will be covered until 4:35 p.m.
Now, if she then bakes it uncovered for an additional 35 minutes,
Add another 35 minutes to the previous time,
This means the chicken will be cooked for a total of 45 minutes,
10 minutes covered + 35 minutes uncovered.
By adding 45 minutes to the starting time of 4:25 p.m., we find that the chicken will come out of the oven at 5:10 p.m.
Hence,
The time will be 5:10 p.m.

Answer:
yes
Step-by-step explanation:
A negative exponent in the numerator is the same as a positive exponent in the denominator (and vice versa). So, the first two expressions are equivalent.
An exponent is an indication of repeated multiplication. So, the 2nd and 3rd expressions are equivalent.
Any product can be decomposed to a product of its factors. So, the last two expressions are equivalent.
All of the expressions are equivalent.
