Figure ABCD is a parallelogram. What are the lengths of line segments AB and BC?
AB = 4 BC = 16
AB = 4: BC = 8
AB = 10; BC = 20
AB = 10; BC = 28
Answers
Answer:
AB = 10; BC = 28.
Step-by-step explanation:
It is given ABCD is a parallelogram. In a parallelogram opposite sides are equal.
AB=DC and AD=BC.
Substituting the given values in terms of x ad y we have:
3y-2=y+6 and 2x-4=x+12
Solving for x and y ,
3y-y=6+2 and 2x-x=12+4
2y=8 and x=16.
y=4 and x=16.
AB=3y-2 and BC=x+12
AB=3(4)-2 and BC= 16+12=28.
AB=10.
The correct answer is AB = 10; BC = 28.

f (x) =x² - 3x - f
find the value of f(1) and f-(2)
f (1) = ______
and f (-2) = _____
Answers
Answer:
for every x in the domain of f, f -1[f(x)] = x, and
for every x in the domain of f -1, f[f -1(x)] = x
Step-by-step explanation:
f(1) and f(-2) means to replace x in the equation with the number inside the parenthesis and then solve.
f(1) = (1)^2 -3(1) -f = 1 -3 -f = -2-f
f(-2) = (-2)^2 -3(-2) -f = 4 + 6 - f = 10-f

y - 2 = 0
Step-by-step explanation:
find slope first:
(2-2)/(5+1) = 0/6 or 0
now use 'y=mx+b' to find the y-intercept (the 'b'):
2 = 0(5) + b
2 = b

y = 2

An airplane ticket has an area of 119 square centimeters. Its perimeter is 48 centimeters. What are the dimensions of the ticket?
Answers
Answer:
17cm ×7cm
Step-by-step explanation:
Assuming that the airplane ticket is a rectangle,
let the length and the breadth of the ticket be L cm and B cm respectively.
LB= 119 -----(1)
2(L +B)= 48
L +B= 48 ÷2
L +B= 24 -----(2)
From (2):
L= 24 -B -----(3)
Substitute (3) into (1):
B(24 -B)= 119
24B -B²= 119 (expand)
B² -24B +119= 0
(B -17)(B -7)= 0 (factorise)
B -17= 0 or B -7= 0
B= 17 or B= 7
Substitute the values of B into (3):
L= 24 -17 or L= 24 -7
L= 7 or L= 17
∴ The dimensions of the airplane ticket is 17cm ×7cm.

You are saving to buy a speed boat. Starting today, you will put $1,000 into an investment account. Each month thereafter, your contribution will be .1% (.001) higher than the month before, so that your contribution next month will be .1% higher than today, and so forth and so on. The investment account has a periodic monthly interest rate of .4% (.004). Ignore taxes. You will make contributions until 5 years from today.
At the end of five years, when you put in your last contribution, how much will you have saved?
Answers
Answer:
You will have saved $69,612 after five years.
Step-by-step explanation:
This can be calculated using the for formula for calculating the future value of a growing annuity as follows:
FV = C * (((1 + r)^n - (1 + g)^n) / (r - g)) ……………………………………… (1)
Where;
FW = future value or amount you will have saved after five years = ?
C = first deposit = $1,000
r = periodic monthly interest rate of = 0.4%, or 0.004
g = growth rate of contribution = 0.1%, or 0.001
n = number of months = 5 years * 12 = 60
Substituting all the values into equation (1), we have:
FV = $1,000 * (((1 + 0.004)^60 - (1 + 0.001)^60) / (0.004 - 0.001))
FV = $1,000 * 69.612001854052
FV = $69,612.00
Therefore, you will have saved $69,612 after five years.

a Cylindial water tank carries a volume of 150 lwhen it's tell full.The water tank has a base surface with a diameter of 140 cm. what is the height of the water tank.
Answers
Answer:
9.744180189 cm
Step-by-step explanation:
1 liter = 1 dm³ (cube with 10cm side lengths) =
= 10×10×10 cm³ = 1000 cm³
the volume of a cylinder is
base area × height
and the base area is a circle
area = pi×r²
r (radius) is half the diameter.
so, we know
volume = 150000 cm³
r = diameter/2 = 70 cm
so, we have
150000 = pi×r² × height = pi×70² × height =
= pi×4900 × height
1500 = pi×49 × height
height = 1500 / (pi×49) = 9.744180189... cm

The annual interest rate on a credit card is 15.30% cm. If a payment of
$300.00 is made each month, how many months will it take to pay off an
unpaid balance of $2,590.67? (Round to 1 decimal place)
Assume that no new purchases are made with the credit card.
The number of months is _______
Answers
Answer:
It will take 10 months to pay off the unpaid balance.
Step-by-step explanation:
Given that the annual interest rate on a credit card is 15.30%, if a payment of $ 300.00 is made each month, to determine how many months will it take to pay off an unpaid balance of $ 2,590.67, the following calculation must be performed:
(2,590.67 x 1.1530) / 300 = X
2,987.04 / 300 = X
9.95 = X
Therefore, it will take 10 months to pay off the unpaid balance.
Exhibit 11-3 The contents of a sample of 26 cans of apple juice showed a standard deviation of 0.06 ounce. We are interested in testing to determine whether the variance of the population is significantly more than .003. The null hypothesis _____. a. should not be rejected b. should be rejected c. should be revised d. None of these answers are correct.
Answers
Answer:
a. should not be rejected
Step-by-step explanation:
H0 : σ² = 0.003
H1 : σ² > 0.003
We obtain the test statistic :
χ² = [(n - 1) * s²] ÷ σ²
s = sample standard deviation = 0.06
n = sample size = 26
σ² = 0.003
χ² = [(26 - 1) * 0.06²] ÷ 0.003
χ² = (25 * 0.06²) / 0.003
χ² = 30
Using the Pvalue from χ² calculator :
Pvalue = 0.2242
Using α = 0.05
Pvalue > α; we fail to reject the Null
