the 1st, 5th and 10th terms of a linear sequence are GP. if the sum of the 2nd and 8th term of the linear sequence is 30 find the first term
Answer:
12 or 15Step-by-step explanation:
Let the first term is a and common difference is d.
Given:
a, a₅ and a₁₀ form a GP ⇒ a₅/a = a₁₀/a₅a₂ + a₈ = 30a = ?Use the equation of nth term:
a₅ = a + 4da₁₀ = a + 9da₂ = a + da₈ = a + 7dAccording to the given we have:
(a + 4d)² = a(a + 9d) a² + 8ad + 16d² = a² + 9ad16d² = add(16d - a) = 01. d = 0or
2. a = 16dNow, use the equation of sum:
a + d + a + 7d = 302a + 8d = 30a + 4d = 15a = 15 - 4dCompare the value of a and find d:
1. d = 0
a = 15 - 4*0 = 15, in this case all the terms are same2. a = 16d
15 - 4d = 16d20d = 15d = 15/20d = 0.75Find a:
a = 16*0.75a = 12please help!!!!

What is the slope of the line passing through the points (2, 4) and (5, 6)?
Answer:
C. 2/3
Step-by-step explanation:
To find the slope of a line from two points, use this formula.
[tex]m=\frac{y^2-y^1}{x^2-x^1}[/tex]
The variable 'm' means slope in algebra.
y² means the second y-coordinate and y^1 means the first y-coordinate.
Based on the previous definition, it should be easy to figure out what x² and x^1 mean.
[tex](2,4),(5,6)[/tex]
[tex]m=\frac{6-4}{5-2} =\frac{2}{3}[/tex]
Therefore, the slope of the line passing through the points (2,4) and (5,6) is 2/3.
Let me know if you have any questions.
48 POINTS PLEASE HELPPPPPPP....The formula for the area of a traingle is 1/2 bh, where b is the length of base of the traingle and h is the vertical height. Use the formula to find the height of a traingle with a base length of 8 inches and an area of 39 square inches.
Answer:
h=39/4
Step-by-step explanation:
area of a triangle = 1/2(b*h)
base = 8 inches
area =39 square inches
input the values given:
39=1/2(8*h)
multiply the right side by 1/2
39=(1/2)8h
find half of 8
39=1/2*8 (h)
hence,
39=4h
divide both sides by 4
hence,
39/4=h
Im so confused please help with 5 and 6
Answer:
5)102,78
6)56,56
See THE IMAGE FOR SOLUTION
Answer:
78° and 65°
Step-by-step explanation:
(5)
The 2 angles lie on a straight line and sum to 180° , that is
x + 84 + x + 108 = 180
2x + 192 = 180 ( subtract 192 from both sides )
2x = - 12 ( divide both sides by 2 )
x = - 6
Then
x + 84 = - 6 + 84 = 78°
(6)
the angle opposite 8x is 9x - 7 ( corresponding to the 9x - 7 )
So 8x and 9x - 7are vertical angles and congruent
9x - 7 = 8x ( subtract 8x from both sides )
x - 7 = 0 ( add 7 to both sides )
x = 7
Then
9x - 7 = 9(7) - 7 = 63 - 7 = 56°

Find the value of k such that the line through (k+3,7) and (-5,3 – k) has a
slope of 5/3.
Answer:
k= -14
Step-by-step explanation:
[tex]\boxed{slope = \frac{y1 - y2}{x1 - x2} }[/tex]
[tex] \frac{5}{3} = \frac{7 - (3 - k)}{k + 3 - ( - 5)} [/tex]
[tex] \frac{5}{3} = \frac{7 - 3 + k}{k + 3 + 5} [/tex]
[tex] \frac{5}{3} = \frac{4 + k}{k + 8} [/tex]
Cross multiply:
3(4 +k)= 5(k +8)
Expand:
12 +3k= 5k +40
Bring k terms to one side, constant to the other:
5k -3k= 12 -40
Simplify:
2k= -28
Divide both sides by 2:
k= -14
Jeremy has $1200 in spending money for the fall semester of college. He needs to purchase car insurance at $120 for 4 months, $25 a week to buy his lunch in the cafeteria every day, and $20 bi weekly for entertainment. If the semester is 16 weeks long, will Jeremy have $200 to spend on Christmas presents for his family? Explain
Answer:
Jeremy Will have more than just $200 to spend on Christmas presents.
Explanation :
He has a total of $1200.
He spends a $120 for car insurance. (1)
He needs to spend $25 a week for lunch. He has to do this for 16 weeks so 25*16 = $400. (2)
He needs to spend $20 a week for entertainment. For 16 weeks that'll be 20*16 = $320 (3)
adding (1) (2) and (3)
We get Jeremy's total spending will be $840. Jeremy has $1200.
1200-840 = $360
So Jeremy will have $360 to spend on Christmas present.
Order the number from least to greatest 7,2, square root 8/2
Step-by-step explanation:
The √(8/2) is equal to 2 if you meant that then the order is 2, 2, 7.
If not then the square root of 8 is approximately 2.82842712475 so divide that by 2 and you get

D
In this situation, As we rise to higher attires, the temperature lowers therefore, only Option B [42. 1º. 40.5º. 39. 70. 34.49. 30.00] follows that requirement.
Now show why there are other possibilities wrong
Option A increases with the altitude, which violets the particular condition.Option C again increases at this temperature as the altitude increases and abruptly falls to 20, which is not our condition.option D up to 51.8 sounds excellent, however, this is achievable as is our given situation but the temperature goes to 59.3, therefore, this option is also refused.Learn more:

Ray SP bisects mZRST.
If m RSP = 3X – 2 and m PST = 9x -26
Answer: Find : mZRST
Answer:
RST = 20
Step-by-step explanation:
a ray that divides an angle into two equal angles is called an angle bisector.
So RSP = PST
3 x -2 = 9x - 26
6x = 24
x = 4
RST = 3x -2 + 9x -26 = 20

Given AB with A(3,-1) and B(8, 14), if p lies on AB such that the ratio of AP to PB is 2:3, find the coordinates of P.
The coordinate point P is at (6, 8) given AB with A(3,-1) and B(8, 14), if p lies on AB such that the ratio of AP to PB is 2:3 is (6, 8)
Midpoint is the point that divides a line into two equal parts.
The formula for calculating the midpoint of a line divided within the ratio a:b is expressed as:
[tex]M(X, Y)=(\frac{ax_1+bx_2}{a+b}, \frac{ay_1+by_2}{a+b} )[/tex]
Given the coordinate point A(3,-1) and B(8, 14) and the ratio 2:3
Get the X coordinate of point P
[tex]X = \frac{2(3)+3(8)}{2+3}\\X=\frac{6+24}{5} \\X = \frac{30}{5}\\X=6[/tex]
Get the Y coordinate of point P
[tex]Y = \frac{2(-1)+3(14)}{2+3}\\Y=\frac{-2+42}{5} \\Y = \frac{40}{5}\\Y=8[/tex]
hence the coordinate point P is at (6, 8)

Point K is between points J and L. If JK=x2−4x, KL=3x−2, and JL=28, find JK and KL.
Answer:
Step-by-step explanation:
JK + KL = JL
x² - 4x +3x - 2 = 28
x² - x - 2 = 28
x² - x -2 - 28 = 0
x² - x - 30 = 0
Sum = -1
Product = -30
Factors = -6 , 5 {-6 + 5 = -1 and (-6)*5 = -30}
x² + 5x - 6x - 30 = 0 {Rewrite the middle term}
x(x + 5) - 6(x + 5) = 0
(x + 5)(x - 6)= 0
x -6 = 0 {X +5 = 0 is ignored as measurement will not be negative}
x = 6
JK = x² - 4x
= 6² - 4*6
= 36 - 24
JK = 12
KL = 3x -2
= 3*6 - 2
= 18 - 2
KL = 16

Select the choice that translates the following verbal phrase correctly to algebra:
the difference of m and 7 increased by 15
Options:
m − (7 + 15)
7m + 15
(m − 7) + 15
m − 7 ÷ 15
Answer:
(m - 7) + 15
Step-by-step explanation:
A difference is the result of a subtraction, so the difference of m and 7 is
m - 7
An increase is obtained by addition, so to increase the difference by 15, add 15 to the difference.
(m - 7) + 15
