Answer:
all of them, possibly excepting the 4th term
Step-by-step explanation:
The recursive formula is good if you have terms near the one of interest. It might be used for the 4th term, but that would require that you compute the three previous terms:
7, 5, 3, 1 . . . . requires 3 subtractions
It can be about as easy to calculate ...
a4 = 7 -2(3) = 1 . . . . requires two* subtractions and a multiplication
__
However, for the 7th, 11th, and 106th terms, it is impractical to list all previous terms. The explicit formula is a better choice.
A. a4 = 7 -2(3) = 1
B. a7 = -1 +10(6) = 59
C. a106 = 2 +5(105) = 527
D. a11 = -3 +4(10) = 37
_____
* The explicit formula is ...
an = a1 +d(n -1)
The operations identified in this formula (in the order required by the Order of Operations) are subtraction, multiplication, and addition. For a negative common difference, that amounts to two subtractions and a multiplication.
For manual evaluation, the work involved in using the recursive or explicit formulas for the 4th term is about the same, if the arithmetic is easily done mentally (as here).
Draw a diagram to represent each of these situations. Then write an addition expression that represents the final temperature.
The temperature was 80 ℉ in Arizona and then fell 20 ℉ during the night.
The temperature was -13 ℉ in Minneapolis and then rose 9 ℉ in the morning.
The temperature was -5 ℉ in Denver and then fell 8 ℉ by the morning.
Answer:
1) 80+(-20)
2) -13+9
3) -5+(8)
I don't quite know how to explain
Just think about 1) 60 is the new temperature, in order to have an addition problem we're going to have to use negative numbers. Since we had to subtract 20, in order to use addition it would be 80+(-20).

3. Marta can buy a 6-pack of 15-ounce cans of broth for $11.29 or three
32-ounce containers for $10.97. Which is the better buy? (Example 1)
Answer:
the second one
Step-by-step explanation:
if you were to divide the price by ounces the first one would be .1254444444444444 per ounce while the second one would be .1142708333333333 per ounce so the second one is better.
at a basketball game at team made 58 successful shots they were a combination of one and two point shots the team scored 98 points in all right and solve a system of equations to find out the number of each type of shot
Answer:
There were 18 1 point goals and 40 2 point goals
Step-by-step explanation:
Let the number of one point shots be x and the number of two point shots be y
Total number of shot is 58
x + y = 58 ••••(i)
Then;
Total of 1 point is 1 * x = x
Total of 2 points is 2 * y = 2y
x + 2y = 98 ••••••(ii)
x = 98-2y
Put this in 1
98-2y + y = 58
-y = 58-98
y = 40
x = 58-40
x = 18

Use the remainder theorem to verify this statement.
(x+5) is a factor of the function f(x) = x^3 + 3x^2 - 25x - 75
1. Find the (product, quotient, difference, sum) of f(x) and x + 5
2. The (quotient, remainder, sum, discriminant) of this operation is 0
3. Therefore, (x+5) is (not a factor, the opposite, a factor, the simplified form) of function f
4. So f ([-75, 5, -5, 75)] = 0
1. quotient
2.remainder
3. a factor
4. 5
Step-by-step explanation:
i just took the test
The expression (x + 5) is a factor of given function f(x).
So the remainder of the function will be zero.
Remainder theorem:The given function is,
[tex]f(x) = x^3 + 3x^2 - 25x - 75[/tex]
We have to check (x + 5) is a factor of the given function.
Equate (x + 5) is equal to 0.
x + 5 = 0
x = -5
Substitute x = -5 in given equation.
[tex]f(-5)=(-5)^3+3(-5)^2-25(-5)-75\\\\f(-5)=-125+75+125-75\\\\f(-5)=0[/tex]
Since f(-5) = 0. Therefore, (x + 5) is a factor of given function f(x).

I'm writing a short story and I'm stuck on what should happen next. could you give me some ideas?
"M-Mr. Jacks!¨ Kate exclaimed, she turned her head to face him. His back was facing the sun and all she could see was the dark outline of his body. Kate stood up frantically, ¨You made it!¨ she was so excited. She noticed it was only him and wondered how everyone else was. “Did anyone else make it out?¨ she asked. He just stood there, no response. Instead, he walked closer, close enough for kate to actually see him. It wasn't Mr. Jacks. Standing there was a shadowy humanoid figure, it's presence gave her chills. Kate stepped back in fear. The shadow tilted it's head in an unnerving matter then lunged at her. ¨Ack!” Kate exclaimed, barely dodging it's attack. Although it ripped her shirt she was fine. W-what the heck, Kate thought. It lunged at her again, completely missing. Terrified, Kate started running, whatever this thing was she knew that she did not want to be caught up in it's attack. The shadow started chasing after her, it's form shifted, the legs got longer and the fingers were transformed into long dagger-like weapons. Oh no. oh no no no no. She thought and started running even faster Kate was running for a long time and was running out of breath, while the shadow was gaining on her. Well this is it i guess. She thought, breathing heavily. There's nothing i can do. Tears started forming in her eyes, even though this might be her last moments she had a smile on her face. At least this is better than starving to death in that bubble. Then all of a sudden Kate heard a gunshot. She looked behind her and this beautiful african american girl stood there, finger on the trigger. Another shot was fired and the shadow fell to the ground, shiveled up on the floor. The girl had short puffed hair, cold dark eyes, and had scars that covered her body. ¨Are you alright?¨ she called out. Kate fell to her knees and sighed in relief. Oh thank god. The girl walked over to her, ¨whats your name hon?¨ she asked. Kate looked up and replied, ¨My names kate and do you mean if i'm physically or mentally alright?¨ Which made the girl chuckle. ¨you seem fine to me¨ she said. ¨The names Alyiah.¨

Ed's new car has a value of $23,500, but it is expected to depreciate at a rate of 7.5% per year. What is the value of Ed's car after 7 years? Round to the nearest dollar, as needed.
$0
$142,162
$13,616
$14,720
Answer:
$13,616
Step-by-step explanation:
For each year we will have to constantly decrease it by 7.5%
23,500 - 7.5%
= 21,737.5
= 21,737.5 - 7.5%
= 20,107.1875
= 20,107.1875 - 7.5%
= 18599.1484375
= 18599.1484375 - 7.5%
= 17204.2123047
= 17204.2123047 - 7.5%
= 15913.8963818
= 15913.8963818 - 7.5%
= 14720.3541532
= 14720.3541532 - 7.5%
= 13616.3275917
Definitively we will get the answer $13,616

what is y=-4/3x-4 in standard form
Answer:
4x + 3y = - 12
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
Given
y = - [tex]\frac{4}{3}[/tex] x - 4 ( multiply through by 3 to clear the fraction )
3y = - 4x - 12 ( add 4x to both sides )
4x + 3y = - 12 ← in standard form
Carrie and Alex are playing hide and seek Alex stands at the house to count Carrie runs 25 m west and finds nowhere to hide. She Continues 60 m north to the tree
Answer:
65mStep-by-step explanation:
Since we are not asked what to find, we can as well calculate the displacement of Carrie.
Displacement will be gotten using Pythagoras theorem;
Given
direction through west x = -25m
direction through north y = 60m
Required
Displacement d
According to the theorem;
d² = x²+y²
d² = (-25)²+(60)²
d² = 625 + 3600
d² = 4225
d = √4225
d = 65 m
Hence the displacement of Carrie is 65m
A soccer ball on the ground was kicked with an initial velocity of 35 ft/sec at an elevation angle of 40º. Create a set of parametric equations to model the path of the soccer ball. Approximately how far away did the soccer ball hit the ground?
19 feet
26 feet
38 feet
52 feet
Answer:
38 feet.
Step-by-step explanation:
From the question given above, the following data were obtained:
Initial velocity (u) = 35 ft/s
Angle of projection (θ) = 40º
Acceleration due to gravity (g) = 9.8 m/s²
Range (R) =?
Next, we shall convert 9.8 m/s² to ft/s². This can be obtained as follow:
0.3048 m/s² = 1 ft/s²
Therefore,
9.8 m/s² = 9.8 m/s² × 1 ft/s²/ 0.3048 m/s²
9.8 m/s² = 32.15 ft/s²
Thus, 9.8 m/s² is equivalent to 32.15 ft/s².
Finally, we shall determine how far away the soccer ball hit the ground (i.e range) as shown below:
Initial velocity (u) = 35 ft/s
Angle of projection (θ) = 40º
Acceleration due to gravity (g) = 32.15 ft/s²
Range (R) =?
R = u² × Sine 2θ / g
R = 35² × Sine (2×40) / 32.15
R = 1225 × Sine 80/ 32.15
R = 1225 × 0.9848 / 32.15
R = 37.5 ≈ 38 feet.
Thus, the soccer ball hit the ground 38 feet away.
