the sum of the first three terms of a sequence Is 42 The fourth term is 24. find u1 and the common difference
[tex]10=2d[/tex]
Given:
The sum of the first three terms of a sequence Is 42.
The fourth term is 24.
To find:
The u₁ and the common difference
Step-by-step explanation:
nth term of a sequence is
[tex]u_n=u_1+(n-1)d[/tex]
where, u₁ is first term and d is common difference.
4th term is 24.
[tex]u_4=u_1+(4-1)d[/tex]
[tex]24=u_1+3d[/tex] ...(i)
Sum of nth term of an AP is
[tex]S_n=\dfrac{n}{2}[2u_1+(n-1)d][/tex]
Sum of first three terms is 42.
[tex]S_3=\dfrac{3}{2}[2u_1+(3-1)d][/tex]
[tex]42=\dfrac{3}{2}[2u_1+2d][/tex]
Divide both sides by 3.
[tex]14=u_1+d[/tex] ...(ii)
On subtract (ii) from (i), we get
[tex]10=2d[/tex]
[tex]5=d[/tex]
Put d=5 in equation (ii).
[tex]14=u_1+5[/tex]
[tex]14-5=u_1[/tex]
[tex]9=u_1[/tex]
Therefore, the first term is [tex]u_1=9[/tex] and common difference is [tex]d=5[/tex] .

Step-by-step explanation:
-x12 + x7 = 0
Factorization:
−x7(x − 1)(x4 + x3 + x2 + x + 1) = 0
Solutions based on Jenkins–Traub algorithm:
x1 = … = x7 = 0
x8 = 1
x9 = −0.809017 − 0.587785i
x10 = −0.809017 + 0.587785i
x11 = 0.309017 − 0.951057i
x12 = 0.309017 + 0.951057i
The length of a rectangular field is twice its breadth. If the perimeter of the field is 150m . Find the dimensions of the rectangle.
Answer:
length=50m
width=25m
Step-by-step explanation:
perimeter is the distance all round,hence
2(l+w)=2(2x+x)=
4x+2x=6x=150
6x=150x
x=25
l=50m
w=25m
Sarah’s parents are concerned that she seems short for her age. Their doctor has the following record of Sarah’s height:
Age: 36,48,51,54,57,60
Height: 82,93,94,98,99,103
Answer:
a) Please find the attached scatter plot
b) Y = 0.85·X + 51.843
c) The intercept = Sarah's height at birth
The slope = Sarah's monthly growth rate
d) Sarah's height in 50 years (600 months) will be 221.198 inches
d) The generality of the population stop growing taller when they reach 216 months old
Step-by-step explanation:
a) Please find attached the scatter plot included here
b) From Microsoft Excel, we have;
N = 6
(ΣX)² = 93636
ΣX = 306
ΣY = 569
ΣXY = 29325
ΣX² = 15966
The equation for the least squares regression line is Y = b·X + a
Where;
[tex]a = \dfrac{\sum Y - b\sum X}{N}[/tex]
[tex]b = \dfrac{N\sum XY - \left (\sum X \right )\left (\sum Y \right )}{N\sum X^{2} - \left (\sum X \right )^{2}}[/tex]
Substituting the values, gives;
[tex]b = \dfrac{6 \times 29325- 306 \times 569}{6 \times 15966 - 93636} = 0.85[/tex]
[tex]a = \dfrac{569 - 0.85 \times 306}{6} = 51.48\bar 3[/tex]
The equation of the least squares regression line is Y = 0.85·X + 51.843
c) The intercept gives the Sarah's height at birth, while the slope gives the increase in Sarah's height every month
d) In 50 years, which is equivalent to 600 months, we will have;
Y = 0.85 × 600 + 51.843 = 561.843 cm
2.54 cm = 1 inches
Therefore;
561.843 cm = 561.843 cm/2.41 × inches/cm ≈ 221.198 inches (18.43317 feet)
Sarah's height in 50 years (600 months) = 221.198 inches
d) The reason for the impossibly large height is that the generality of the population stop growing taller by 18 years of age which is 216 months.

B is the midpoint of AC. AB = 2x + 12 and AC = 10x - 12.
Find the following:
x:
AB:
BC:
AC:
Answer:
Step-by-step explanation:
If B is the midpoint of AC, then AB = BC and AB+BC = AC
AB +AB = AC
2AB = AC
2(2x+12) = 10x-12
4x+24 = 10x-12
collect like terms:
4x-10x = -12-24
-6x = -36
x = -36/-6
x = 6
Get AB:
AB = 2x+12
AB = 2(6)+12
AB = 12+12
AB = 24
Since AB = BC, hence BC = 24
AC = AB+BC
AC = 24+24
AC = 48

Solve: 4x(x - 3)(x + 5)(2x - 7) = 0
Answer: 8x⁴ - 12x³ - 176x² + 420x
Step-by-step explanation:
First multiply 4x by (x - 3) which = 4x² - 12x. Next multiply (4x² - 12x) by (x + 5) which = 4x³ + 8x² - 60x. Multilying our new trinomial with the next binomial: (4x³ + 8x² - 60x)(2x - 7) = 8x⁴ + 16x³ - 120x² - 28x³ - 56x² + 420x. Combining like terms: 8x⁴ - 12x³ - 176x² + 420x. Notice that when you reduce and factor, you will end up with the starting binomials meaning this solution is correct.

Use the figure to find the measures of the numbered angles. Then, explain how you determined each of the numbered angle measures.
Answer:
see below
Step-by-step explanation:
∠1 = 61°
∠2 = 119°
∠3 = 61°
∠4 = 119°
∠5 = 119°
∠6 = 61°
∠7 = 119°
-------------------------------
∠1 = 61° = as given
∠2 = 119° = ( 180 - 61 ) = 119°
∠3 ≅ ∠1 opposite angles are equal (congruent)
∠4 ≅ ∠2 opposite angles are equal (congruent)
∠5 ≅ ∠2 or parallel
∠6 ≅ ∠3 ≅ ∠1
∠7 ≅ ∠5

R
A. 30°
B. 75°
C. 60°
D. 45°
Answer:
D. 45
Step-by-step explanation:
All angles have to = 180°
60 + 75 + <RVE = 180°
135 + RVE = 180°
180 - 135 = 45° RVE
RVE = 45°
Another way to check your answer:
Add all of the angles, and it should equal 180°
60 + 75 + 45 = 180°
Correct!

The caffeine content of 8-ounce cans of a certain cola drink is approximately normally distributed with mean 33 milliogram. A randomly selected 8-ounce can containing 35mg of caffeine is 1.2 standard deviations above the mean. Approximately what percent of 8-ounce cans of the cola have a caffeine content greater than 35mg?
Answer:
12%
Step-by-step explanation:
Step 1
We find the standard deviation
A randomly selected 8-ounce can containing 35mg of caffeine is 1.2 standard deviations above the mean.
Mean = 33mg
35 = Mean - 1.2(standard deviation)
35 = 33 + 1.2(standard deviation)
35 - 33 = 1.2(standard deviation)
2 = 1.2(standard deviation)
Standard deviation = 2/1.2
= 1.6666666667
= 1.67
Therefore, the standard deviation is 1.67
Step 2
Using the z score formula
Z score = x - μ/σ
x = 35mg
μ = mean = 33mg
σ= standard deviation = 1.67
= 35 - 33/1.67
= 1.1976
Probabilty value from Z-Table:
P(x<35) = 0.88446
P(x>35) = 1 - P(x<35)
= 1 - 0.88446
= 0.11554
Converting to percentage = 0.11554 × 100
= 11.554%
≈ 12%
Therefore, the percent of 8-ounce cans of the cola having a caffeine content greater than 35mg is approximately 12%
Using the normal distribution, it is found that 11.5% of 8-ounce cans of the cola have a caffeine content greater than 35mg.
In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.In this problem, a randomly selected 8-ounce can containing 35mg of caffeine is 1.2 standard deviations above the mean, which means that the z-score is Z = 1.2.
The percent of 8-ounce cans of the cola have a caffeine content greater than 35mg is 1 subtracted by the p-value of Z = 1.2, so:
Looking at the z-table, Z = 1.2 has a p-value of 0.885.
1 - 0.885 = 0.115
11.5% of 8-ounce cans of the cola have a caffeine content greater than 35mg.

Roberto Clemente, born in Puerto Rico, became the first Latino baseball player to be inducted in the National Baseball Hall of Fame in 1973. He held many records including reaching 3,000 career hits. During that game, the umpire briefly stopped the game to give the ball to Clemente, who tossed it from second base to the first base coach. If the first base coach was standing 3 feet behind first base and Clemente was standing on second base, which is 90 feet from first base, which expression describes the distance between Clemente and the first base coach?
Answer:
93ftStep-by-step explanation:
Kindly find a simple sketch of a baseball pitch, the circle with a dot inside represents the first base coach(don't mind my drawing please I will improve).
So, from the diagram, we can see that the expression that describes the distance and the first base coach is
y=90+3
y=93
so the distance between Roberto Clemente and the first base coach is 93ft
Suppose g(x) = 3 + 5x.

Step-by-step explanation:
Substitute the given value for g(x) and solve the 2-step equation for x.
g(x) = 3 + 5x
23 = 3 +5x

roger goes shopping and buys an $112 item but has 30% off coupon. if tax is 7%, how much will roger pay altogether?
Step-by-step explanation:
Cost = $112
30% discount coupon on the item he's going to buy
=$112 × 30/100 (or you can write 30%)
=$168/5 ($33.6)
7% tax on the item=$112 × 7/100(or you can write 7%)
= $196/25 ($7.84)
Total amount altogether=$112 - $33.6 - $7.84
=$70.56
