Answer:
see explanation
Step-by-step explanation:
The n th term ( explicit formula ) of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given a₁₂ = - 95 and a₃₇ = - 270 , then
a₁ + 11d = - 95 → (1)
a₁ + 36d = - 270 → (2)
Subtract (1) from (2) term by term to eliminate a₁
25d = - 175 ( divide both sides by 25 )
d = - 7
Substitute d = - 7 into (1) and solve for a₁
a₁ + 11(- 7) = - 95
a₁ - 77 = - 95 ( add 77 to both sides )
a₁ = - 18 , thus
[tex]a_{n}[/tex] = - 18 - 7(n - 1) = - 18 - 7n + 7 = - 7n - 11
[tex]a_{n}[/tex] = - 7n - 11 ← explicit formula
--------------------------------------------------------------
The recursive formula allows a term in the sequence to be found by adding the common difference d to the previous term, thus
[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] - 7 with a₁ = - 18 ← recursive formula

Determine where the decimal point belongs in each product. 1.7 × 2.5 = 425 The decimal point belongs after the . 3.62 × 1.7 = 6154 The decimal point belongs after the .
Decimal point in product is the sum of the decimal points in the numbers which we are multiplying.
For ex :
2.6 × 6.7 = 17.42
1 + 1 = 2
For, 1.7 × 2.5 the sum of decimal in each number is 1 and 1 .
So, decimal in product is at 2 i.e 4.25 .
For, 3.62 × 1.7 the sum of decimal in each number is 2 and 1.
Decimal in product is at 2 + 1 = 3 i.e 6.154 .
Therefore, solution is 1.7 × 2.5 = 4.25 and 3.62 × 1.7 = 6.154 .
Hence, this is the required solution.

The punch layout for a piece of 12 gage sheet metal is as shown. What is the area of the cross hatched center "star" shape ? Show all calculations! circle radius 1 foot Not drawn to scale I
Answer:
.86 square feet.
Step-by-step explanation:
Directions
You have to do this by following directions.
1, Go one circle to your right. Make it the top circle.
2, Drop a perpendicular from the circle you've just been directed to.
3. Draw until you hit the center of the circle below the circle you started your line from. You should get a square.
Find the area of the square.
Each side of the square is 2 feet. You get that because the side of the square = 2 radii -- one radii from the two circles in the center.
Area Square = s^2
Area Square = 2 * 2
Area Square = 4
Find the are of the circles
The 4 central circles that are touching (2 to the left and 2 to the right) are each are 1/4 of a full circle. 4 * 1/4 circle Area = 1 full circle.
Area = pi * r^2 = 3.14 * 1^2 = 3.14
Find the area of the star
Area of the star = area of square - area of circle.
Area of the star = 4 - 3.14
Area of the star = .86 sqr feet

40 is what percent of 25. Hint: There are 2 correct answers.
А160%
B 62.5%
C 1600%
D625/1000
E 160/100
F1600/100
Answer:
B and D
Step-by-step explanation:
Hope this helps :3
if it did pls mark brainliest
Answer:
A & E
Step-by-step explanation:
First, multiply 40 by 100, giving you 4000. You then divide 4000 by 25, where you will get a quotient of 160. Now, this can be represented as 160% or 160/100 because a percentage is always out of 100.

On monday a farmer sold 25,196 pounds of potatoes on tuesday he sold 18,023 pounds. On wensday he sold some potatoes in all he sold 62,049 pounds of potatos
Given :
Total pounds of potatoes, T = 62,049.
On Monday a farmer sold 25,196 pounds of potatoes on Tuesday he sold 18,023 pounds.
To Find :
How many pounds he sold in Wednesday to end the stock.
Solution :
Potatoes sold in Wednesday = Total - Potatoes sold in Monday - Potatoes sold in Tuesday
= 62049 - 25196 - 18023 pounds
= 18830 pounds
Hence, this is the required solution.
What would an equation be for a line with a slope of 3 and a y-intercept of 7?
Answer:
y = 3x + 7
Step-by-step explanation:
Using the formula y = mx + b we can create this equation.
m = slope
b = y -intercept
based on the information provided I know that
Slope = 3
and
y-intercept = 7
Substitute:
y = mx + b
y = 3x + 7
y = 3x + 7 is the equation when the slope is 3 and the y intercept is 7.
Let us use the slope-intercept form for this, with m as the slope and b as a constant.
y = mx + b
7 = 3(0) + b [since the y-int is 7, the x value will be zero]
b = 7
y = 3x + 7

Answer:
y - 3 = (1/2)(x - 4)
Step-by-step explanation:
The graph is hard to read, but we can make assumptions about the x- and y-values shown. The y-intercept appears to be (0, 1) and the blue dot appears to be (4, 3). Let's try finding the equation of the line using this assumed data:
The point-slope equation is y - k = m(x - h), where (h, k) is a point on the line and m is the slope of the line.
We need the slope of the line. Recall that m = rise/run. Going from (0, 1) to (4, 3), x (the 'run') increases by 4 and y (the 'rise') increases by 2. Thus, the slope is m = rise/run = 2/4, or 1/2.
Substituting the known values into the point-slope equation y - k = m(x - h), we get:
y - 3 = (1/2)(x - 4)

What is the inverse of the function f(x) = 4x + 8?
O h(x) = 1/4x-2
O h(x) = 1/4x+2
O h(x) = 1/2x-2
O h(x) = 1/2x+2
[tex]f(x)=4x+8\\y=4x+8\\x=4y+8\\\\[/tex]
Proceed the inverse. Swap the x and y.
[tex]x-8=4y\\\frac{x}{4}-\frac{8}{4}=y\\y=h(x)\\h(x)=\frac{x}{4}-2\\h(x)=\frac{1}{4}x-2[/tex]
So the answer is first one.
