The seventh term of an arithmetic progression is equal to twice the fifth term. The sum
of the first seven terms is 84. Find the first term.
Answer:
a₁ = - 24
Step-by-step explanation:
The n th term of an AP is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given a₇ = 2a₅ , then
a₁ + 6d = 2(a₁ + 4d) = 2a₁ + 8d ( subtract 2a₁ + 8d from both sides )
- a₁ - 2d = 0 → (1)
The sum to n terms of an AP is
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]
Given [tex]S_{7}[/tex] = 84 , then
[tex]\frac{7}{2}[/tex] (2a₁ + 6d) = 84
3.5(2a₁ + 6d) = 84 ( divide both sides by 3.5 )
2a₁ + 6d = 24 → (2)
Thus we have 2 equations
- a₁ - 2d = 0 → (1)
2a₁ + 6d = 24 → (2)
Multiplying (1) by 3 and adding to (2) will eliminate d
- 3a₁ - 6d = 0 → (3)
Add (2) and (3) term by term to eliminate d
- a₁ = 24 ( multiply both sides by - 1 )
a₁ = - 24
In City A, the temperature rises 7 degrees F from 8AM to 9AM. Then the temperature drops 6 degrees F from 9AM to 10AM. In City B, the temperature drops 2 degrees F from 8AM to 9AM. Then the temperature drop 4 degrees F from 9AM to 10AM. Write an expression that represents the change in temperature from 8AM to 10AM for each city. Simplify and interpret each sum.

Answer:
Step-by-step explanation:
The question is incomplete. Here is the complete question.
the batting wang xiu ying uses to fill quilts has a thermal conductivity rate of 0.03 watts (W) per meter(m) per degree celsius. what is the batting thermal conductivity when w/cm•c
Given
K = 0.03W/m°C
Required
Convert K to W/cm°C
Since 1m = 100cm,
K = 0.03w/1×100cm°C
K = 3×10^-2w/10² cm°C
K = 3 × 10^-2w/10² cm°C
K = 3w× 10^{-2-2}cm°C
K = 3w×10^-4cm°C
K = 0.0003w/cm°C
Answer:
0.0003
Step-by-step explanation:
DID IT ON KHAN
and Since 1m = 100cm,
K = 0.03w/1×100cm°C
K = 3×10^-2w/10² cm°C
K = 3 × 10^-2w/10² cm°C
K = 3w× 10^{-2-2}cm°C
K = 3w×10^-4cm°C
K = 0.0003w/cm°C

Write an equation in slope-intercept form for the line that passes through the given point and is perpendicular to the graph of the given equation.
Equation: y-intercept of 1, 3x – y = 5
Answer:
The equation is [tex]y=-\frac{1}{3}x+1[/tex]
Step-by-step explanation:
You have the y-int, so you just need to find the slope, which is the negative reciprocal of A/B since it is perpendicular. Plugging in the numbers gets you the above equation.

Four brothers each bought two hot dogs and a bag of chips at the football concession stand. If the bag of chips was $1.25, and the total was $18.20, what was the price of one hot dog
Your answer is 1.65.
(may have a hard time explaining it)
SO, there are 8 hotdogs and 4 bags of chips, 4 times 1.25 is 5, and 18.20 minus 5 is 13.20, so the chips are out of the equation. Now all we must do is divide what's left (13.20) by 8:
13.20/8=1.65

What is the slope of the line whose equation is y-4=5/2(x-2)
Answer:
m=5/2
Step-by-step explanation:
To find the slope, use the formula y=mx+b. m is the slope. The line with the equation y-4=5/2(x-2) gives us a slope of m=5/2. Hope it helps!

Find the value of x in the triangle shown below.
Answer:
55
Step-by-step explanation:
I believe it's 55 because the triangle has to equal 180
so I subtracted 70 from 180 and x can't be 70 because they don't have the same lengths
subtracting 70 from 180 gave me 110 then I divided by 2 since both the top angle and x would have the same angle in degrees xD
Can someone please help me
Answer:i think 8
Step-by-step explanation:
Two Angles are Supplementary when they add up to 180 degrees. They don't have to be next to each other, just so long as the total is 180 degrees.
Find the points of the equation 3x – 7y= 21 which intersects the x - axis and y-axis.❤THANKS YOU
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
To find the x-intercept ;
Just need to put 0((zero)) instead of y in the equation.
Let's do it....
3x - 7y = 21
3x - 7(0) = 21
3x - 0 = 21
3x = 21
Divided sides by 3
3 / 3 × x = 21 / 3
x = 7
Thus the x-intercept is 7 .
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
To find the y-intercept ;
Just need to put 0((zero)) instead of x in the equation.
Let's do it....
3x - 7y = 21
3(0) - 7y = 21
0 - 7y = 21
-7y = 21
Divided sides by -7
-7 / -7 × y = 21 / -7
y = - 3
Thus the y-intercept is -3.

given
week pay period.
George: 9.5h+35s−2(12)
Mary: 13.5h+11.25d−2(37)
their combined earning is the sum of the individual earning
9.5h+35s−24

23h+35s+11.25d-98
The expression is 23h+35s+11.25d-98
