Answer:
267
Step-by-step explanation:
We are given the expression: 6 (d - f) +f
The value of the expression when d= 47 and f = 3 is :
6 (47 - 3) +3 = 6×(44) + 3 = 264 + 3 = 267

The ellipse with the equation 9x2 + 16y2 = 144 ________.
a. is in Position II
b. has no symmetry
c. is in Position I
d. has no foci
Please help me figure out how to determine this!!
The ellipse with the equation stated above is:
Position I (Option C )
An ellipse is a circle that has been extended in one direction such that it is no longer a circle but an oval.
Solution
In order to determine the position of the ellipse with the above equation, we can start by simplifying the equation.
Hence, 9x² + 16y = 144 becomes
x²/16 + y²/9 = 1 (We arrive at this by dividing both sides of the equation by 144);
The x-axis is the major axis because the biggest denominator is under the x² term.
Thus the coordinates of the vertices are as follows:
(± a, 0); (0, ± b)
Hence:
a² = 16 → a = 4
b² = 4 → b = 2
Hence the coordinates are:
(± 4, 0); (0, ± 2)
Given the above, the eccentricity is given as:
e = √(1 - (3/4)^2 = (√7)/4 = 0.6614378
Hence the ellipse is: 0.66

Hakeem buys a two-gallon bottle of juice for $25.60. What is the unit rate of the cost
of the juice per fluid ounce?
1 gallon = 4 quarts
1 quart = 2 pints
1 pint = 2 cups
1 cup=8 fluid ounces
-
Before you try that problem, answer the question below.
How many fluid ounces of juice did Hakeem buy?
try
Answer:
256 fluid ounces
Step-by-step explanation:
2 gallons = 8 quarts
8 quarts = 18 pints
18 pints = 32 cups
32 cups = 256 fluid ounces
1 gallon = 4 quarts x 2 that's 2 gallons = 8 quarts
1 quarts = 2 pints x 8 that's 8 quarts = 16 pints
1 pints = 2 cups x 16 that's 16 pints = 32 cups
1 cup = 8 fluid ounces x 32 that's 32 cups = 256 fluid ounces

Answer:
[tex]\boxed{\sf{d=4}}[/tex]Step-by-step explanation:
In order to solve this equation, you must isolate it on one side of the equation.
Use the distributive property.
Distributive property:
⇒ A(B+C)=AB+AC⇒ -24+12d=2(d-3)+22
Multiply.
⇒ 2(d-3)+22
⇒ 2d-2*3
⇒ 2*3=6
⇒ 2d-6
Rewrite the problem down.
⇒ 2d-6+22
⇒ -6+22=16
⇒ 2d+16
⇒ -24+12d=2d+16
Then, you add by 24 from both sides.
⇒ -24+12d+24=2d+16+24
Solve.
⇒ 12d=2d+40
Subtract by 2d from both sides.
⇒ 12d-2d=2d+40-2d
Solve.
⇒ 12d-2d=10d
⇒ 10d=40
Divide by 10 from both sides.
⇒ 10d/10=40/10
Solve.
Divide the numbers from left to right.
⇒ 40/10=4

Write a rule for the nth term of the geometric sequence for which a1=11 and a4=88
Answer:
[tex]a_{n}[/tex] = 11 [tex](2)^{n-1}[/tex]
Step-by-step explanation:
the nth term of a geometric sequence is
[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]
where a₁ is the first term and r the common ratio
given a₁ = 11 and a₄ = 88 , then
11 r³ = 88 ( divide both sides by 8 )
r³ = 8 ( take cube root of both sides )
r = [tex]\sqrt[3]{8}[/tex] = 2 , then the nth term is
[tex]a_{n}[/tex] = 11 [tex](2)^{n-1}[/tex]

Also let y be the distance from Allison to the bottom of the line.
