Answer:
You may be asked to "determine algebraically" whether a function is even or odd. To do this, you take the function and plug –x in for x, and then simplify. If you end up with the exact same function that you started with (that is, if f (–x) = f (x), so all of the signs are the same), then the function is even.

Two blueberry farms are similar in shape. The ratio of the side lengths of the farms is 4 : 5, and the smaller farm has a perimeter of 280 yards. The cost to dig a trench is $0.75 per yard. What is the cost to dig a trench around the larger blueberry farm?
Answer: $262.50
Step-by-step explanation:
The yards are sized in a ratio of 4:5.
Assuming the perimeter of both farms is x, the formula to calculate it will be;
[tex]\frac{4}{4 + 5} x = 280\\\\x = 280/\frac{4}{9} \\\\x = 630 yards[/tex]
The perimeter of the larger fence will therefore be;
= 630 - 280
= 350 yards
The cost to dig the trench will be;
= 350 * 0.75
= $262.50

Answer:
95° and 85°
Step-by-step explanation:
Same-side interior angles between parallel lines are supplementary:
(9x +14) +(8x +13) = 180
17x = 153
x = 9
9x +14 = 81 +14 = 95
8x +13 = 72 +13 = 85
The two angle measures are 95° and 85°.

Answer: Oliver is correct
Step-by-step explanation:*mine doesn’t have the line and stuff to show u how to explain it*
Use the graph to determine which statement is true about the end behavior of f(x).
As the x-values go to negative infinity, the function’s values go to negative infinity.
As the x-values go to negative infinity, the function’s values go to positive infinity.
As the x-values go to positive infinity, the function’s values go to negative infinity.
As the x-values go to positive infinity, the function’s values go to zero.

Lula is buying meatballs for her beach theme party each package contains six beach balls generate the set of ordered pairs for the ratio relationship between the number of beach balls in the number of packages for a total of one, two, three, and four packages
Answer:
{(1, 6), (2, 12), (3, 18), (4, 24)}
Step-by-step explanation:
We are given that ...
(packages, balls) = (1, 6)
Multiplying by 2, 3, and 4, we find the set of ordered pairs to be ...
{(1, 6), (2, 12), (3, 18), (4, 24)}

Julie, a cafeteria manager, is making a large amount of chicken soup to serve for lunch tomorrow.
For every 2 cups of carrots she uses in the soup, she uses 3 cups of celery. If she uses 18 cups of
celery, how many cups of carrots did she use?
Answer:
12 cups
Step-by-step explanation:
Divide the given amount of celery, 18 cups, by the number of cups in the given ratio, 3 cups.
[tex]18/3=6[/tex]
This number is how many times the ratio Julie used. Use this number to multiply the ratio number of carrots, 2 cups
[tex]2*6=12[/tex]
Julie uses 12 cups of carrots in her chicken soup
[tex]\frac{12}{18}=\frac{2}{3}[/tex]

A bookshelf contains 10 mysteries, 8 biographies, and 6 science fiction books. A book is randomly selected, replaced, then another is selected. Find the probability, P(biography, then science fiction) as a simplified fraction
Answer:
Biography= 8/24= 1/3
Science Fiction= 6/24= 1/4
Step-by-step explanation:
The probability for biography is (biography/total amount of books.)
8/24= 1/3
The probability for science fiction is (science fiction/ total amount of books.)
6/24= 1/4
Calculate the distance travelled by a bus in 2 hours which moves with the velocity of 22 meter per second
Answer:
The distance traveled by the bus is 158,400 meters.
Step-by-step explanation:
Velocity and Distance
The velocity of a body can be calculated with the formula:
[tex]\displaystyle v=\frac{d}{t}[/tex]
Where d is the distance traveled in a time t.
The bus travels by t=2 hours and has a velocity of 22 m/s. We need to solve the above equation for d as follows:
[tex]d=v.t[/tex]
We first need to convert the time to seconds. Recall there are 3,600 seconds in one hour, thus t = 2*3,600 = 7,200 sec.
Now we calculate the distance:
[tex]d=22 m/\not{s}*7,200\not{s}= 158,400\ m[/tex]
The distance traveled by the bus is 158,400 meters.
Determine if 0.71875 is rational or irrational and give a reason for your answer.
Answer:
Rational number
Step-by-step explanation:
Given
[tex]Digit = 0.71875[/tex]
Required
Determine if it is rational or not
[tex]Digit = 0.71875[/tex]
Convert to fraction
[tex]Digit = \frac{71875}{100000}[/tex]
Divide numerator and denominator by 25
[tex]Digit = \frac{2875}{4000}[/tex]
Divide numerator and denominator by 25
[tex]Digit = \frac{115}{160}[/tex]
Divide numerator and denominator by 5
[tex]Digit = \frac{23}{32}[/tex]
The above is a rational number because it can be expressed as a fraction of two integers

Judy is working at a retail store over summer break. A customer buys a $50 shirt that is on sale
for 20% off. Judy computes the discount, adds sales tax of 10%, and tells the customer how
much he owes. The customer insists that Judy first add the sales tax and then apply the discount.
He is convinced that this way he will save more money because the discount amount will be
larger.
Answer:
Same final price, no differenceStep-by-step explanation:
Way 1, final price
Apply discount and then apply tax
(50 - 20%) + 10% =50*0.8*1.1 = $44Way 2, final price
Apply tax and then apply discount
(50 + 10%) - 20% = 50*1.1*0.8 = $44As we see both ways reveal same final price so no difference
Answer:
It does not matter in which order the discount and tax are computed.
Step-by-step explanation:
Judy first takes 20% off which gives a new price of $50(0.8)=$40. She then adds the 10% sales tax for a final price of $40(1.1)=$44. The customer first adds 10% for a new price of $50(1.1)=$55. He then takes 20% off for a final price of $55(0.8)=$44.
The customer is right to say that the discount amount will be larger, it is $11 opposed to $10 with his method. But the additional $1 just gets subtracted from the tax amount that was added in the first step. So the final price is the same in both cases.
